SCIENTIFIC REPORT 2013
2013 | scientific rEport | PAGE 2
FOREWORD
The year 2013 has passed very quickly, measured in our own ICPE-CA’s time. It is somehow in
contradiction with overall expectation, but this accelerated transition of ICPE-CA’s time was determined by
the effervescence of our internal life. It was the year in which the ICPE-CA team excellence developed in
the previous years gave the first results: we are now aware of the value of our business vector to market
and economy value. This orientation could best describe us if we follow the new topics of our National Core
Programme and the commitment of our project responsibles, together with established groups, are aimed to
achieve the objectives. There are projects with high scientific potential and medium-term encouraging economic
prospects, but also topics whose accomplishment will be the basis of market successes. Thus, we believe that
our National Core Programme is certainly a starting point for bold researches and the beginning of competitive
products on the market. Of course, all these topics belong to the main areas of our excellence: advanced materials,
micro- and nanotechnologies, energy efficiency in conversion and consumption. This last area was strengthened
by the contribution of our new colleagues, transferred temporarily from IPCUP Ploieşti, which by their skills in
complementary fields, have provided the synergy much desired in our multidisciplinary researches.
2013 is the year of the vision of our future development in full agreement with the medium and long term
strategy of ICPE-CA. Our project having the acronym “PROMIT” within SOP-IEC Programme, completed in
2012, was prepared for a future edition, also successfully, so this year we can enjoy of other project having the
acronym “PROMETEU” within SOP-IEC Programme, which develops rapidly new laboratories and upgrading
the laboratories already existing. The center of gravity of the flame is now on laboratories working in the field
of energy. Completion of the project will generate new capabilities of our institute.
If we look from the perspective of this year to 2013, we could admire the work of colleagues in promoting
new projects, from NPRDI II (National Programme for R&D&I) or other national and international
Programmes, of which we must mention: STAR (Space Technology and Advanced Research) Programme, Clean
Sky (Aeronautical Research) Programme, ESA (European Space Agency) Programme, SEE (South East Europe
Transnational Cooperation Programme), EEA (European Economic Area) Research Programme, CEA - RO
(Atomic Energy Commission) and others.
An important achievement of the last year, announced by us in 2012, is signing the contract with FAIR
GmbH, Darmstadt, Germany, for the execution of some proficient electromagnets and particular current sources.
From the end of 2013 the contract is ongoing, providing us income of about 4 ME. There is not only one effect:
we expect at involvement in international well-known consortia leading to similar achievements.
In 2013 contracts with trade companies increased in value; our colleagues from Laboratory for
Electromagnetic Compatibility have brought a great contribution by a technical work for electromagnetic
isolation of five laboratories from Institute of Atomic Physics (IFA).
Awarding in 2013 by AGIR (General Association of the Engineers in Romania) President with the prize
in the “Materials” field for industrial assimilation of a product, respectively the technology for biocompatible
ceramics, used at bone corrections, rewarded our efforts in transfer of knowledge in industry.
We have entered in 2014 with optimism, the year in which we would like to put in practical applications
some scientific results from the past and to prepare whose to come.
Dear colleagues, employees or colleagues transfer temporarily, thank you for what you have created in
2013. Together we must express our gratitude to all our partners who helped us in our research achievements.
In 2013 we were pleased to welcome the prestigious guests from home and abroad.
I thank to those who prepared this report; I also thank the members of the Administrative Council Board,
with whom I drafted and approved our strategy, have promoted it and have monitored it; I also thank to the
ICPE-CA Scientific Council. Not finally, I thank to the members of the Directory Board, with whom I assured
the daily coordination of the ICPE-CA efforts.

2.1. History
Upon registration in the Trade Register in 2001 until the reorganization in 2004 when he became a national
institute, ICPE-CA has acted as a Joint Stock Company. The initial share capital subscribed of 3,811,075 lei –
contribution in kind – was entirely owned by Romanian state as sole shareholder and was fully paid from the
establishment of the company.
Since August 2004, by the Romanian Government Decision (no. 1282, from August 24, 2004), company
ICPE-CA was reorganized as National Institute for Research and Development in Electrical Engineering ICPE-CA
Bucharest. Its patrimony, consisting of private state property which passed in institute management and own
property, is on December 31, 2013 of 64,040,614 lei.

Also, INCDIE ICPE-CA provides technical support, supplying of scientific and technological services for
companies or any interested customers, by testing laboratories:
Laboratory for Testing and Characterization of Electrotechnical Materials and Products;
Laboratory for Electromagnetic Compatibility;
Laboratory for Evaluation of Thermal Behaviour of Products and Materials;
Laboratory for MEMS and NEMS Testing.
The Technology transfer from research to the business as the main method of stimulating the economic
growth, applied in the world, is performed by INCDIE ICPE‑CA by establishing/development of spin-offs: SC
ROMNEOMAG SRL, SC SPINGREENBOATS SRL.
Also in this respect, in 2013 was established „ICPE-CA” MEGEOL SRL in order to bring the research results
closer to economic environment through prototyping (electric engines and wind generators), as well as by
making them for industrial applications.
Another important channel of technology transfer is the Enterprise Europe Network in which INCDIE ICPE‑CA
is partner (within the BisNET Transylsania‑1 project).
The development of partnership with scientific and technology parks is another goal that our institute has
developed. Thus, by the Order of Delegated Minister for Higher Education, Scientific Research and Technological
Development no. 4901MD from August 27, 2013, was approved to operate the Romanian-Chinese Scientific and
Technology Park International Green Innovation Park – IGIP; the founding members are INCDIE ICPE‑CA, Avrig
City Hall and Chinese partner, Beijing Chengtong Reorient Investment Consultancy Co.Ltd.
IGIP Park headquarters is INCDIE ICPE‑CA, 313 Splaiul Unirii, sector 3, Bucharest, Romania.
2.5. Strategic changes in organizing and functioning of
INCDIE ICPE‑CA3:
As a necessity to support the expansion of ICPE‑CA research and development area, was established working
office CORBU ICPE-CA, becoming an important strength in the protection and conservation of the environment
and renewable energy.
The desire to achieve goals of National RDI Plan and to achieve the energy projects, INCDIE ICPE‑CA has
increased the research area including conventional energy such as oil and gas. In this regard, ICPE‑CA transfers
temporarily a part of employees IPCUP Ploieşti for a period of 6 months (June 10 – December 31, 2013).
In July 2013, following the loss of building from Josef Attila Street no. 4, Sf. Gheorghe city, Covasna County,
and after a judicial decision, ICPE‑CA was forced to restructure their technology transfer activities carried out
by the Business and Technology Incubator ICPE‑CA (ITA ECOMAT ICPE-CA). Thus, this activity was redirected to
the working office of the town Avrig – Mârşa, Sibiu County, in order to maintain and strengthen the competitive
advantage on the market and ensure the viability of business.

With a special opening to applied research in electrical engineering, over the
years the institute has approached those projects to develop the scientific, economic
and social environment.
From the beginning until now, the institute has continued its programme of
cooperation and partnership with entities from its field. Thus, we can mention a
large number of scientific articles published in ISI journals (39 ISI papers and 15
papers published in ISI conference proceedings/publications in 2013), scientific /
technical papers published in other journals non-quoted ISI (25 non-ISI papers),
scientific papers presented at international conferences (107 papers), products (40),
technologies (2), procedures (122) and services resulting from research, important
technological transfers (2) made by institute, all these meaning continuous scientific,
technological, economic and social progress.
As technical and technological success, must be highlighted and attending in
various national and international trade fairs and exhibitions with most successful
achievements of the institute for economy and industry (International Exhibition of
Inventions – Geneva – Switzerland, International Salon Brussels – EUREKA – Belgium,
Romanian Research Exhibition 2013 – Bucharest - Romania, Nanotechnologies
Exhibition IRANNANO 2013 – Teheran – Iran, ATEE 2013 (Advanced Topics in
Electrical Engineering) – Bucharest, Romania), as well as organizing of 3 scientific
events which increased the scientific visibility of our institute.
The Institute is well represented in the field of intellectual property through 22
patents granted by OSIM (Romanian State Office for Inventions and Trademarks), 9
General information
patents submitted in 2013 at OSIM and continuous attending at main international
Inventions shows, being awarded with many national and international medals and
awards (10 awards obtained in 2013).
Also in this respect, in 2013 was established „ICPE-CA” MEGEOL SRL in order
to bring the research results closer to economic environment through prototyping
(electric engines and wind generators), as well as by making them for industrial
applications.
The development of partnership with scientific and technology parks is another
goal that our institute has developed. Thus, by the Order of Delegated Minister for
Higher Education, Scientific Research and Technological Development no. 4901MD
from August 27, 2013, was approved to operate the Romanian-Chinese Scientific and
Technology Park International Green Innovation Park – IGIP; the founding members
are INCDIE ICPE‑CA, Avrig City Hall and Chinese partner, Beijing Chengtong Reorient
Investment Consultancy Co.Ltd.
IGIP Park headquarters is INCDIE ICPE‑CA, 313 Splaiul Unirii, sector 3, Bucharest,
Romania.
Certainly, these achievements have led to reach the strategic objectives required
by the institute mission, namely, research and development in the field of electrical
engineering, supporting the progress based on knowledge, for the benefit of the
whole society.

Thermo-insulating coatings with “microspheres” ceramic-TMC
ABSTRACT
The project has the aim to achieve a coating material
environmentally friendly, anticorrosive with properties
thermal and electrical insulation, made from a waterbased polyvinyl paint and addition of microspheres
ceramic type α Al2O3.
The alumina microspheres hollow were obtained by
sol-gel technique and ion extraction.
Was achievement the experimental models insulating
coating material with ceramic microspheres.
It was determined specific characteristics of
the coating material experimental models: thermal
conductivity, dielectric permittivity and corrosion
resistance.
INTRODUCTION
At the moment, there is a global concern in the
development and use of „hollow ceramic microspheres”
as fillers in coatings [1]. Coatings are used in various
industries; many companies use such materials in order
to achieve economic benefits.
Coating materials with “hollow ceramic microspheres”,
creates a thermal barrier in the material and thermal
energy saving occurs. Internationally there are companies
specializing in the manufacture and marketing of such
materials: 3MTM, Microsphere NASA, HY-TECH Thermal
Solutions and U.S. Schenna [2, 3]. Microspheres are
spherical particles with cavity; they have micron and
submicron dimensions, the wall cavity to 10% of particle
diameter. The microspheres cavity is closed, achieving
a cavity of “thermos” type, which will create a thermal
barrier and acoustic the structure of covering material
[4-9]. There are many techniques of obtaining hollow
ceramic microspheres, discussed by different authors
such as Wilcox and M. Berg and Chatterjee [7-11].
In this context, the general objectives of the
project are:
- the experimentation of the composition of
ceramic microspheres using environmentally friendly
precursors;
- the characterization of the ceramic microspheres;
- achievement experimental model anticorrosive
thermo-insulating coating material with ceramic

EXPERIMENTAL
In the previous stages of the project was obtained
αAl2O3 the ceramic microspheres using the sol-gel
technique combined with the technique of extraction
ions of the emulsion.
It was used as raw materials: alumina precursor
salt and a range of solvents and toxic gelling agents
(amines “carcinogens” 12th Report on Carcinogens,
ROC, June 10, 2011).
The technology steps of ceramic microspheres are
the following:
I. Preparation of the alumina
II. Preparation of water-oil type emulsion (W/O)
III. Preparation oxide gel microspheres.
From the experiments performed were selected two
models of ceramic microspheres namely MAE7 and
MAE9.
The gel microspheres were claimed at 1200oC and
characterized by specific analysis to determine the
morphology (X-ray diffraction, electron microscopy).
It was achieved:
- experimental models of type α Al2O3 ceramic
microspheres (MAE5-MAE10) obtained by sol-gel
technique and ion extraction, of these two models
were selected that presented the best morphology
MAE7, MAE9;
- were synthesized the hollow ceramic microspheres,
with average diameter of 24.5μm to 34μm and up to
the minimum of 9.7μm and wall thickness 10% of the
diameter of the microspheres (fig. 1, 2). The results
are comparable with those in the scientific literature.

There have been designs of coating materials
with a water-based paint, vinyl type, with ceramic
microspheres αAl2O3 type, as follows:
- two model thermo-insulating coatings with
microspheres type αAl2O3 (8% MFA 7) - VME 2 Sample 3;
- the stability and durability of the coating was
determined by electrochemical techniques. Shown in
Figure 2 is the electric potential variation depending on
current electrical intensity, as follows:
- the control sample analyzed in the absence paint
layer introduced 1%NaCl solution has corrosion
current of approx. 0.10 mA/cm2;
- sample 2 painted ca. 150μm polyvinyl type paint
based on water without the addition of microspheres
has mixed current I0 = 0.05 mA/cm2;
- sample 3 with added 8% microspheres has mixed
current I0 = 0.021 mA/cm2.
Fig. 4.Variation of permittivity imaginary
component with frequency of the electric field
for P1 and P3 sample
Addition of 8% αAl2O3 microspheres leads to lower
dielectric loss in the frequency of 50 Hz to 3.17 for
sample P3 with 8% to 7.79 that show P1 control
sample. This can be explained by the fact that at low
frequencies, the interfacial polarization occurs from
interfaces created by paint and Al2O3. Thus, the air
gaps stored in αAl2O3 empty microspheres are a cause
of reduction relative permittivity. Thermal conductivity
measurement results show that it is modified depending
on the composition of the coating (Fig.5).
Fig.3. The electric potential variation depending on
current electrical intensity
From the data analysis it is observed that, one control
sample without the addition of ceramic microspheres
have higher thermal conductivity values than sample 2
with 5% addition of ceramic microspheres 8% added
ceramic microspheres. It is observed that, addition
of double microspheres corrosion resistance of the
coating to increase corrosion resistance is due to the
presence αAl2O3 ceramic microspheres.
Dielectric

measurement
results
performed on samples: P1 control (without addition of
microspheres) and P3 with 8% addition of microspheres
are shown in the graphs below:
For all samples measured are found a decreasing
of the permittivity normal component with increasing
frequency.
Fig. 5. Variation of thermal conductivity with
temperature
The average value of thermal conductivity for the
coating material model with microspheres has values
around 0.3-0.6 W/mK. The decrease in thermal
conductivity is explained by the presence of ceramic
microspheres who also carrying a thermal barrier in
coating material.
CONCLUSIONS
The main conclusions drawn from the experiments
carried out are:
1. The gel microspheres were calcined and
characterized by XRD and SEM. The results confirm

the formation of the αAl2O3 with rhombohedral
structure and hexagonal axis. The electron
microscopy confirmed the spherical morphology
with hollow of a gel particles calcined in models of
selected ceramic microspheres (MAE 7 MAE 9):
In the synthesis process of microspheres, the
technological parameter have a significant role, a
variation of a parameter or failure to comply may
lead to various forms of ceramic particles (non spherical, without cavity);
The use of ceramic microspheres as filler additions
in coating materials have printed a decrease
in thermal conductivity obtaining value of the
thermal conductivity of 0.3 W/mK at a content of
5% microspheres;
The corrosion resistance of insulating coating
material increases with increasing of the
concentration of ceramic microspheres added to
the material;
The presence of 8% concentration of αAl2O3
microspheres in a coating materials lead to a
reduction of dielectric loss.

EXPERIMENTAL
The following types of results were obtained in order
to accomplish the objectives proposed in 2013:
Objective 1: Development of nonoxide ceramic
materials
l The following experimental work was carried out to
achieve the functional model of a thin layer of ceramic
material based on aluminium nitride thin layers were
made of material A2.2 (95% AlN 3% Y2O3 +2%
CaF2) on a copper and aluminium. Both the ceramic
material (as samples) and thin layers produced from it
were characterized in terms of structural, mechanical,
dielectric (stiffness and dielectric permittivity) and
heat (thermal conductivity).
l Experimental
works were also effectuated
for certification of ceramic material based on AlN with
electro-insulating and thermal conductive properties
Objective 2: Carbon fibers
l Were characterized experimental models of carbon
fiber made in earlier stages (FC 1500, FC 1800, FC
2000). Samples of experimental models of carbon
fiber were subjected to extreme electrochemical
applications, including:
- Loop in the -1.6 to 2.6 VESC, the potential scanning
speed of 200 mV/s for 3 hours;
- Excessive anodizing +2.6 VESC for 3 hours;
l In diverse environments: 1% NaCl solution, KOH
solution pH=13, HNO3 solution, pH=0.4.
l Polarization curves were drawn before and after
electrochemical pre-specified requests [14].
l Experimental models of carbon fiber studied were
characterized from physico-chemical and morphostructural by: X-ray diffraction, FTIR-ATR, scanning
electron microscopy (SEM, FIB), qualitative elemental
analysis by dispersive energy spectral technique
(EDS) and were determined: electrical resistivity,
tensile strength and elasticity modulus, coefficient of
partially heat transfer, and the thermal conductivity
of the carbon fiber for both the reference sample
(not subject electrochemical applications), as well as
electrochemical applications.
l In the second stage were performed of experimental
models of graphite fiber. Experimental models developed
were characterized in terms of morphological structure
by XRD, SEM, TEM, AFM / STM microscopy.
Objective 3: Research on CNT achievement
Attaining the proposed objectives in 2013, were
performed the following:

(Si or SiO2-coated Si) using magnetron sputtering;
l characterization samples deposited catalytic on nickel
substrates by XRD, SEM, AFM;
l obtaining experimental models of multi-walled
CNT by the CVD method using catalyst substrates
achieved, the physical and structural characterization

and SEM microscopy;
l Preliminary testing of micro electro-spinning of
PVA solution, namely PVA/CNT, morphological
characterization by SEM microscopy.
Objective 4: Magnetic materials
l There were obtain and characterized structurally
and magnetically 28 models. In order to obtain
nanocomposites based on Nd2Fe14B / α-Fe were
developed and molded in induction furnace, vacuum/
controlled atmosphere (argon) three types of
composition: Nd11Fe83B6 (corresponding Nd2Fe14B
+ 5% Fe), Nd10.5Fe84B5.5 (corresponding Nd2Fe14B
+ 10% Fe), Nd10Fe85B5, (corresponding Nd2Fe14B
+ 15% Fe). From structural determinations made
by X-ray diffraction (XRD) and scanning electron
microscopy (SEM) revealed that: both phases can be
observed, Nd2Fe14B and, respectively, crystallized Fe.
Diffraction spectra of powders obtained by grinding
ribbons, presents both phases in the crystalline state.
l From magnetic determinations made using Brockhaus
Messtechnik hysterisgraph, resulted the following:
hysteresis cycles obtained from characterization
showed the influence of the addition of iron in
composition; has been observed promising values of
the magnetic properties, for the compaction powders
obtained from ribbons, the two methods for obtaining
the ribbons showed the influence of parameters in
obtaining powders and revealed the need of nucleation
of the two magnetic phases.
l It was found that for the extra iron compositions
obtained by sintering in plasma, magnetic properties
are determined largely by the request conditions
required for processing.
Objective 5: Composite material with mechanical
strength and ability to absorb electromagnetic waves
high
l There
were structurally, mechanically, and
electromagnetically characterized control specimens
of cooper, brass, and bismuth as well as two composite
materials: one based on ferrite and another based on
carbon fibbers in wax matrix.
For
the
functional
characterization,
three
measurement methods were employed: vector network
analyzer with waveguide method, vector network
analyzer with antennas, and the measurement method
with antennas in the anechoic chamber, in the 1 – 10
GHz frequency range.
l Regarding the shielding materials (SM) for reducing
RCS, the electromagnetic characteristics of some
structures that simulate metamaterials were
investigated. According to the equivalent circuits,
micro-solenoids were designed and built so that to
exhibit resonances around 1 GHz. These resonance
frequencies were theoretically calculated based on
the estimated values of the intrinsic inductivity and
the capacitance between turns.
l Preliminary tests aimed to determine the reflectivity
(S11) and the transmission (S21) of some metamaterials
with such structure, in three different configurations,
using the three types of measurements.
l Experimental SM were designed and achieved for
impedance matching layers, resonant layers for
improving the electromagnetic absorption capability
of the multilayer materials (radar range). They were
achieved by respecting the principles of obtaining the
Salisbury and Dallenbach shields.

pressure of 5-10 MPa, sintering temperature of 900°C,
dwell time of 5 minutes, temperature increase rate of
100oC/min and cooling rate of 50oC/min. The junctions
were characterized in terms of morphological structure
by electron microscopy and of mechanical properties
such as resistance to bending/shear determined
by three-point method, with the carbon material

From the polarization curves for carbon fibers
electrochemically applied in 1% NaCl solution results
that on the anodic branch, there are two distinct
processes with different Taffel slopes: first, in +600÷1200mVESC, corresponding oxygen evolution and the
second, over 1200mVESC corresponding emission of
chlorine (Figure 5-7), the maximum sample currents

Following the request electrochemical stress, no
significant changes were observed in the behaviour of
the samples studied [14], indicating maximum stability
of carbon fiber samples obtained at 2000°C.

Regarding the behaviour of carbon fiber samples
strongly acidic and oxidizing environment, it was found
that the anodic process is still in the discharge of oxygen
but only the most positive potential 1200mVESC. The
samples studied had limited stability, observing, first,
the weakening of carbonaceous material.

Regarding the thermal behaviour of the samples
studied, it was found that the heat transfer of the partial
coefficient values (α) of carbon fibers studied, has not
changed significantly as a result of electrochemical
applications, which are determined primarily by the

determined in part by the heat transfer coefficient (α)
of the order of 75000 W/m2K for FC 1500, 85000 W/
m2K for FC 1800, respectively 90000 W/m2K for FC

characterized the “control” and reference specimens
(cooper, brass, bismuth), as well as the samples of
experimental composite materials developed in this
project (fig.24).

From the measurements depending on the wave
impedance it has been demonstrated that the
maximum reflection loss is attained around 50 ohms –
the characteristic impedance of the TEM cell.
In order to achieve the metamaterials, first were
made micro-solenoids (fig. 2) using two types of
conductors: ISAZIN – CuNi23Mn1.5 (enamel insulation)
and ISOTAN – CuNi44Mn1 (cotton insulation).
In the tests with ordered, anisotropic, arrangement,
the aim was to emphasize the electromagnetic
characteristics of the micro-solenoids, given that the
magnetic field lines of the wave are parallel with the
coil’s axis. These tests were made both in the coaxial
cell of the vector analyzer and in the TEM cell, the coils
being, in this case, concentrically arranged on some
discs of insulating material (Fig.26).
By using the vector analyzer, electromagnetic
shields of type Salisbury and Dallenbach were tested
in order to:

Given the results obtained in two stages in 2013,
it is found that the carbon material elaborated by
carbonizing PAN fiber has a stable electrochemical
behaviour in alkaline and neutral and limited stability
in strongly acidic oxidizing environments. These
findings correlated with adequate mechanical strength
indicates that these materials can be used as flexible
anode material for various applications in neutral and
strongly alkaline medium.

Development of new materials and devices for controlled drug
delivery with applications in biomedical engineering
ABSTRACT
The main purpose of the project is to study,
development and testing of medical devicesbioresorbable ceramic biomaterials based on calcium
phosphates (carriers of therapeutic substances), and
granular products for applications in maxillofacial
surgery and dental treatment, implantology and general
surgery of bone addition (skull bone defects repair).
To meet the needs of medical devices has aligned
with international requirements and performance, at
this stage of the project were carried out and tested β-TCP medical devices for applications in maxillofacial
surgery (granular product PG β-TCP, 125-500μm ) and
neurosurgery (cranial bone substitute- experimental
model).
INTRODUCTION
Bone loss due to trauma, infection or removal of
a large tumour laid serious problems both the doctor
as well as the patient. Nowadays, one of the biggest
challenges in materials science and technology is
developing a new generation of biomaterials for “repair”
the various parts of the body [1, 2]. Biomaterials and
in particular bioceramics are a special category of
materials essential to modern health care [3]. Of great
interest is bioresorbable ceramics mainly of tricalcium
phosphate (β‑TCP), embedded in the bone tissue will
undergo gradually degradation (resorption), along
with the implant substitution of a new bone tissue.
The most important calcium phosphate bioceramics
are based on hydroxyapatite (HAP/FAP) or tricalcium
phosphate (β‑TCP) and combinations thereof [3, 4]. It
is estimated that worldwide investments were made
by ~5mld. Euro, of which 2mld. Euro came from the
private sector (according to sources of the European
Commission/2004). Till the year 2015 is estimated a
value of ~ $ 1,000 billion. Annually, the marketing of
these materials means a business of tens of billions of
dollars [5].
The project aims to develop medical devices
for modern health care; main objectives consisted
in elaborating of the documentation for certifying
(expansion) the product PG β‑TCP, 125-500μm, and
the development of bone substitute (synthetic bone –
experimental models (EM) for cranioplasty.
Three stages were finalized within 2 sub‑themes,
as follows:
-
Sub-theme 1: “β‑TCP products for medical
devices”;
-
Sub-theme 2: “Synthetic bone for repairs in
neurosurgery”.

Stage 1 / Sub-theme 1: Preparing documentation
for expansion of certification of β‑TCP product, for
medical devices
The main objective of the stage consisted in achieving
the documentation for certification (extension) of
β‑TCP product, for medical device (PG β‑TCP, 125500μm). Technical dossier of the product covered

expansion of β‑TCP product certification, for medical
devices
The main results are:
-
Compiling the technical dossier of the product
PG β‑TCP, 125 - 500μm;
-
Compiling documents for product certification
(PG β‑TCP, 125-500μm).

CONCLUSIONS
From the results of the characterization carried out on
experimental models have been found:
1. experimental models contain as the majority phase
hydroxyapatite compound, without any decomposition
secondary compounds (unwanted), suggesting a good
stability of hydroxyapatite ceramic compound, including at high sintering temperature (1300˚C);
2. it was obtained experimental microporous models
with controlled values of total porosity (PT = 15-30%),
by controlling the shaping process and changes of heat
treatment diagram, when it can be achieved a balance
between the values of the open and closed porosity
(appearance);
3. mechanical characteristics such as flexural strength
and compression resistance shows values increasing
in proportion to the degree of densification; for
experimental model OS-D were obtained maximum
values of 70.45 MPa and 63.50 MPa respectively,
comparable to values communicated in the literature
for the microporous products obtained by similar
shaping processes.

Rationally designed coordination polymers as precursors for oxide nanomaterials
ABSTRACT
The project aims to develop rational synthetic
strategies leading to novel metallosupramolecular
architectures with pre-established structures by linking
homonuclear alkoxo-bridged Zn(II) nodes into lattices
with various polytopic organic ligands. ZnO particles
will be obtained by the calcinations of the synthesized
Zn(II) coordination polymers.
INTRODUCTION
Coordination polymers consisting of alkoxo-bridged
Zn(II) cores and anionic polycarboxylate spacers have
not been reported so far. Even alkoxo-bridged Zn(II)
systems are still scarce.1,2 Therefore, in this project
we intend to develop a novel class of Zn(II)-based
coordination polymers, that will be further used to
generate nanostructured ZnO materials.

by thermogravimetric analysis (Fig. 4). The continuous
mass loss up to 2000C may be assigned to the
removal of lattice solvents (MeOH/H2O). At higher
temperatures, the compounds exhibit a series of weight
losses, attributed to the elimination of aminoalcohol
and polycarboxylic ligands. The decomposition is
completed at 8000C, with the formation of ZnO.

Cables for medium tension based on radiation processed
polyamide materials
ABSTRACT
The safety operation of electrical cables requires
the investigation of material stability. The effects of
various parameters like composition, environmental
stressors or working conditions can be revealed by the
study of material stability.
INTRODUCTION
Polymer materials used in material engineering
industry as dielectric insulators must show proper
properties related to the long term stability. Because
they are subjected to the permanent action of
oxidative degradation caused by various environmental
(heat or freezing, humidity, ultraviolet exposure) or
functionality (electrical field, mechanical field) factors,
the efficiency in the energy transport is directly related
to the degradation state of insulators, materials must
be inspected to the resistance against degradation.
One specific problem in the cases of polyamide –
based dielectrics is the identification of compatibilization
procedures through which PA6 can be intimate and
stable blended with elastomers. This kind of insulators
is possible to be produced by gamma irradiation and
the final materials are resistant ones.

2. Swelling tests
For the determination of swelling degrees, polymer
samples were immersed in water and toluene according
to standard SR EN ISO175. 1 g specimens of PA, PA/5E,
PA/10E, PA/20E, PA/5L, PA/10L and PA/20L were
weighted and put in the ampoules for processing.
Similar tests were performed on conditioned
materials under environmental parameters:
• Water absorption 24 h/23oC;
• Dry heating 48 h/130oC;
• Freezing 2 h/ - 30oC.
The vials containing toluene were deposited at room
temperature for 3 h.
Studied materials were subjected to swelling at
different temperatures over the range of 20-80oC, after
1 h of conditioning.
For the calculation of swelling degree the following
equation was used:
Q=
X 2 − X1
∗ 100
X1
where: Q - swelling) degree; X2 – weight of
swollen material; X1 – in itial weight of sample.
The nonisothermal chemiluminescence spectra
(fig. 1) prove the influence of elastomer content on
the thermal stability of compounded polyamide 6.
The increase in the ethylene-propylene elastomer
decreases the stability of samples, because the
melting point is lower and the rate of oxygen diffusion
becomes higher.
EXPERIMENTAL
The investigations on stability behaviour were
accomplished on the following composition based on
polyamide PA6: PA control, PA + 10% EPDM, PA +
20% EPDM, PA + 30% EPDM, PA + 5% Lotharder,
PA + 10% Lotharder, PA + 20% Lotharder, PA + 5%
Exxelor, PA + 5% Exxelor, PA + 20% Exxelor.
1. Oxidation tests
The tests on oxidation were carried out as the
thermal resistance experiments bz nonisothermal
chemiluminescence. The device was LUMIPOL 3
(Slovakia).

The results concerning the swelling degree tests
performed at room temperature in water are presented
in figs. 2, 3 and 4. The penetration degree on a
solvent into polymeric materials is in direct relation
with the degree of macromolecule ordering, which
demonstrates the amount of free volume existing in
studied material.
Fig.4. Swelling degree measured in water at
different temperatures
In fig. 5 several nonisothermal chemiluminescence
spectra are presented. They were recorded on sample
subjected to the degradation under environmental
conditions and can be drawn the following
conclusions:
-
The increase in the concentration of elastomer
decreases the oxidation resistance, because the rate of
oxygen diffusion is significant higher,
Fig. 2. Swelling degree measured in water
National projects
Fig. 5. Nonisothermal chemiluminescencemspectra
recorden on pamles aged by water absorption
-
the preservation of these blends at negative
low temperatures does not promote major modifications
in comparison with the other applied environmental
stressors,
-
the most aggressive factor which causes
material degradation is the penetrated water. The
oxidation is advanced by treeing process and the
electrical properties are decreased correspondingly.
Other aspect that must be taken into account is the
synergy between the action of water overlapped on
the influence of electrical field,
-
water absorption produces similar effects
on thermal stability of PA 6 blends with Exxelor and
Lothader, while the other factors like dry heating and
cooling induce different degradation degrees. The
resistance of PA6/Exxelor is rather higher than the
availability of PA6/ Lothader;
-
the concentration of 20 % is not favourable
for the preparation of cable insulation, because of the
lowest thermal stability.
Fig. 6. Nonisothermal CL spectra recorded on the
polymer samples aged by dry humidity
Fig. 7. Nonisothermal CL spectra recorded on the
polymer samples aged by cooling
The real service conditions for electrical cables
influence the heat resistance of polymeric insulations
because, because the intermolecular distances are
different in respect with the action of environmental
factors (different temperatures, water penetration).
From fig. 5-7 it can be considered that the polyamide
blends are not affected by heat, if temperature does
not exceeds 150oC.
National projects
CONCLUSION
The oxidation resistance, which is the main factor
for the selection of electrical insulators is determined
by the composition of polymer sheet and by the
environmental factors that act durinf operation. In this
sense, the compatibilization of PA6 blends represents a
technological criterion for the definition of application
in various economical fields.

Intelligent system for the analysis and diagnosis of collagen-based artefacts (COLLAGE)
ABSTRACT
There were elaborated three general procedures
for thermal characterization of the solid materials and
products by thermal analysis methods (simultaneous
thermogravimetry (TG) + differential thermal analysis
(DTA) or differential scanning calorimetry (DSC);
differential scanning calorimetry (DSC) and dynamic
mechanical analysis (DMA)). The specific conditions in
which these procedures could be used for quantitative
and qualitative of the collagen based materials (pure
collagen, parchments, and tanned leathers) were
specified in four analytical protocols.
INTRODUCTION
The present project takes place from a series
of research projects, scientific papers published in
ISI journals and communications at National and
International Symposia and Conferences [1 – 27]. In
the last 15 years, the specific thermal analysis methods
were elaborated and applied for characterization of
collagen-based materials (pure collagen, parchments,
and leathers). The obtained results were correlated
with those obtained by other techniques (spectroscopic
methods, optical methods etc) and the effects of
environmental factors (heat, humidity, visible and UV
radiations, chemical pollutants) on the parchments and
leathers were put in evidence.
The objectives of the present phase of the project
were:
- dissemination of the results included in the
“Software Platform for analysis and diagnosis” that
was performed in the previous phase of the project;
- elaboration of some general procedures for analysis
by TG, DTA, DSC and DMA methods;
- elaboration of some analytical protocols for
quantitative and qualitative evaluation of collagen
based materials by TG, DTA, DSC and DMA methods.

Power generation system which uses a double - effect wind
turbine in order to ensure the energy autonomy in specific
applications
ABSTRACT
This project intends to develop a system for power
autonomy based on a double-effect wind turbine. Thus,
the project proposes the development up to prototype
stage, of a new type of wind turbine with a rated
power in the range of 10 - 20 kW, based on innovative
aspects: two wind rotors co-axially positioned onto
the same direction drive simultaneously an electrical
generator, achieved especially for this purpose. Based
on this turbine, it is developed a system for electric
energy generation which offers an increased safety
in the electric power supplying of a unit specialized in
the food industry production activities and which will
take over the prototype. INTRODUCTION
The study of double effect wind turbines (counterrotating or not) has begun in the last decade. At
international level, the research is focused on prototypes
in the power range of 0.5÷50 kW. Thus, during 2003
in California, Appa Technology Initiatives tested for 3
months [1] a prototype of 6 kW counter-rotating wind
turbine. The optimum operating conditions of turbines
are investigated also by numerical simulations, using
CFD (Computational Fluid Dynamics) software. Thus,
in [2], a counter-rotating system composed by two
500 kW turbines was studied. Simulations showed
that when operating the turbine at a speed of 10 m/s,
the annual energy production increases with 43.5%
comparing to the case of a single turbine operation.
Electrical generators suited for energy conversion
systems using counter rotating turbines can have a
specific design (both armatures mobile and horizontal
or vertical shaft) or can be developed as classic
generators (in this case requiring a complex system for
power transmission).
The use of permanent magnets significantly simplifies
the design of the electrical machine. The aim of this project for the year of 2013 is to
develop an experimental model of double effect wind
turbine.
The objectives of this project for the year of 2013
consist in:
- Development of an experimental model version;
- Development of the electric generator for the double
effect wind turbine;
- Testing of the electric generator on a specialized
stand;
- Development of the wind blades for the first rotor;
- Development of a system designed for operating
and monitoring the nacelle positioning (with electrical
equipment). Research staff of the project

Design and sizing of a kinetic energy storage system working on flywheel principle
System modelling - optimization of the component elements
ABSTRACT
In order to size a kinetic energy storage system
working on the flywheel principle, it was carried
out a comparative study of the systems used
nowadays for energy storage, allowing thus to
emphasize the advantages and disadvantages of
the flywheel systems use. There are shown the
structure, working principle and main parameters
of a flywheel system, the designing and sizing
procedure of the main components and there
are presented details of the modelling and
optimization of these components: the flywheel,
the electrical machine and the bearing system.
INTRODUCTION
Nowadays there are used following energy storage
systems [1]:
• storage systems with electrochemical batteries:
supercapacitors, Ni-Cd, Li-Ion, Pb-acid, NaS,
metal-air and external electrolyte batteries;
• hydraulic and pneumatic storage systems, on the
principle of water pumping and compressed air;
• mechanical storage systems, with flywheel;
• electromagnetic systems, with storage in
superconducting coils;
• hydrogen storage systems (fuel cells);
• thermal energy storage systems.
The comparative analysis of these systems revealed
the field of use for each system and the advantages
and disadvantages of them.
From the structural point of view, in figure 1 it is shown
a section thru a flywheel energy storage system with
a classical configuration [2]:
Fig. 1. Flywheel system structure
The diagram of the energy transfer it is shown in the
next figure:
Fig. 2. Energy transfer diagram
The main parameters that describe a flywheel system
are [3]:
• energetic storage capacity;
• power and energy density;
• lifetime and no. of charge / discharge cycles;
• flywheel parameters;
• type and parameters of the electrical machine;
• type of the bearing system;
• supplied voltage.
For the design and sizing of the flywheel system it is
necessary to establish the main performances that the
system should meet:
• the system use;
• supplied voltage;
• the output power;

From the point of view of materials, for the flywheel
manufacturing it can be use wood, medium tensile
strength steel, aluminium alloys, titanium alloys,
high tensile strength steel (maraging steel), newest
developments using non isotropic materials, like
glass fiber, carbon fiber and Kevlar. These composite
materials leads to manufacturing costs much lower
than high tensile strength steel and titanium alloys and
also allow achieving high energy density [4].
The kinetic energy accumulated by a flywheel it is
given by the expression [5]:
National projects
From this expression it can be considered that the
main method to increase the energy accumulated by
the flywheel it is to increase the rotation speed. But
this solution has limitations given by the flywheel
material, thru the admissible tensile strength which
has to be higher than the strain which arise do to the
flywheel rotation.
For the calculation of the flywheel moment of
inertia on have to calculate the energy necessary to be
released when the system has to pass in UPS mode, to
ensure a proper operation of equipment that the system
supply. The expression for the moment of inertia is:
With the value of the moment of inertia and choosing
the flywheel material, it can be calculate the volume
of material that leads to the calculated moment of
inertia, allowing determining the size of the flywheel.
For a faster and accurate modelling of the flywheel it
can be used 3D modelling software (e.g. SolidWorks),
which allow to adopt optimal flywheel shape, calculate
the moment of inertia and allow the simulation of the
flywheel behaviour to the high strain which arise during
the high speed rotation.
The electrical machine can be realized in reversed
configuration and has to be foreseen with cooling circuit.
This is required because the flywheel containment has
to be with vacuum, to eliminate the energy loss do to
the friction with air.
Also, it is necessary to use magnetic bearings,
because the high rotational speed that the flywheel
reach.
Using 3D modelling software SolidWorks there have
been created three flywheels, one from steel, one from
titanium and one from carbon fiber. For the flywheel
made from carbon fiber on a titanium alloy part, shown
in figure 3, there have been checked the flywheel
behaviour, from the point of view of strain that arise
during the high speed rotation.
Fig. 3. Flywheel made from carbon fiber
The simulation, made also with SolidWorks software,
emphasized the total tensile strength (according to von
Mises), which arise in the titanium alloy part and in
the carbon fiber part, the distribution of these tensile
strength being shown in the figure 4.
Fig. 4. Tensile strength distribution in the flywheel
made from carbon fiber
CONCLUSIONS
The comparative analysis of the energy storage
systems used nowadays shown that the flywheel
storage systems have significant advantages as:
specific energy relatively small, high lifetime with very
low maintenance, very good efficiency in respect with
the lifetime, low costs in respect to the efficiency and
to the lifetime, very low impact on the environment.
The materials used for the flywheel manufacturing
can be various, from usual and cheap (wood, common
steel), to high quality isotropic materials (special steel,
aluminum alloys, titanium alloys) and to anisotropic
new materials (composite materials with glass fiber,
carbon fiber and Kevlar. Material selection it is made
taking into account the rotational speed at the outer
diameter of the flywheel, which can be as bigger as
the ratio between the tensile strength of the material
and his density it is bigger.
The moment of inertia of the flywheel depends on
the power that the supplied equipment needs, on the
maximum speed of the flywheel and the coefficient of
speed fluctuation.
The disruptive effect which affect the dynamic
behavior of the flywheel and the shaft on which the
flywheel it is installed, request a very good balancing
of the system, both static and dynamic.
The electrical machine which it can be considered as
optimal to drive a flywheel system it’s a synchronous
permanent magnets machine, because it can be operate
very easily as reversible machine and because it can be
made to operate at very high speed, without special
measures to ensure the integrity of the components.
Special measures has to be adopted for the cooling
of the machine, taking into account that, to decrease
the friction loss, the containment of the flywheel has to
be with vacuum, the thermal transfer being difficult.
Magnetic bearings are the best choice that can be
used nowadays for flywheel storage systems, because
National projects
these bearings allows, at reasonable price, to reach
very high rotational speed and very low friction losses,
which means very low power losses.
The modelling performed shown that the composite
materials with carbon fiber allow to manufacture
flywheels with smaller overall dimensions and which
can accumulate higher kinetic energy than the
flywheels made from other materials (steel or titanium
alloys), but have the disadvantage of a more difficult
technology for flywheel manufacturing.

Growing of the efficiency of technological equipments and

Designing of the FA100 ultralight water well drilling rig, fabrication
and experimentation of the prototype of the FA100 ultralight
water well drilling rig
Abstract
F100 ultralight water well drilling rig was made
within this project. F100 ultralight water well drilling
rig is functioning based on the hydraulic rotary drilling
with direct circulation of the drilling fluid principle, it is a
low power driven drilling rig, having mechanical driving
from a small gasoline engine with vertical shaft.
FA100 drilling rig is the most efficient, lightest, end
cheapest drilling rig on the Romanian market today
having the lowest fabrication and exploitation cost but
having very high quality of the drillings and it can solve
the water resources crisis, especially for the small
households from the rural and suburban communities
(where is the worst aspect of the water crisis in our
country), through hydrogeological drillings at the best
price/quality ratio on the market today. Also, FA100 rig can realize installation of the Heat
Pumps in drilled wells having the best price/quality
ratio, allowing the efficient implementation of the Heat
Pumps in our country, which was prohibited till now
just due the very high costs of the drilled wells using
high power heavy drilling rigs.
There were obtained till now the following results
within the stages of the project: 1.The designing of
the FA100 drilling rig; 2.Fabrication of the drilling head
of the FA100 drilling rig.
INTRODUCTION
The actual situation of the researching for the well
drillings for water alimentation and for inhalation of the
Heat Pumps is as follows:
1. There is a differential market with high extremes
for the water drillings in Romania today: a. At the lower
end, there is a market for the water drillings made with
a primitive Middle Ages tool named “CRIVAC”, which
has not more been used in civilized Europe from 19th
century, which can primitive, manually and dry drill only shallow water wells (till H=25m depth), in nitrite
and microorganisms polluted aquifer strata, having
dirty water containing silt and sand without chance
of removing the sand and completing the well using
MAMMOTH pump, having a very low quality of the
water. The wells for installing the Heat Pumps can not
be drilled with this “CRIVAC”.
National projects
b. At the other high end, there is a market for
the water drillings made with heavy high powered
industrial drilling rigs, truck or trailer mounted, having
high driving power (P=100÷200 HP), which are non
ecological drilling, destroying the land-property of the client, rigs which are fitted especially for the industrial
water drillings for the great cities monopolized water
networks and for great water consumers companies
such as COCA-COLA or brewer factories, having huge
costs for drilled and cased meter (more than 100
euro/m), drilling costs that are inaccessible for the small
households from the rural and suburban communities,
just where the water crisis is worst manifesting in our
country today, and costs being inaccessible for Heat
Pump mounting.
2. From abroad, especially in U.S.A. (see DEEP
ROCK Company [1]) there are light and ultralight water
well drilling rigs mechanical driven from small gasoline
engines which can drill at the best price/quality
ratio wells for potable, washing and irrigation water
alimenting and for Heat Pumps mounting.
For these reasons it was occurring the necessity for
making the FA100 drilling rig which can drill wells in
depth, clean and non polluted strata (H=40÷100m)
having a good and stable water flow, with the chance
of removing the sand and completing the well using
MAMMOTH pump, wells for water alimenting and for
Heat Pumps mounting, wells having a far better quality
water than these manually, primitive and dry drilled
with that “CRIVAC”, but wells having an accessible
drilling costs (30÷40 euro/m), far lower than the costs
of drilling using heavy high powered industrial drilling
rigs, truck mounted.
One of the scopes of the PN09350201 NUCLEU
project was the making the FA100 ultralight water
well drilling rig, and the objectives of the project were
researching, designing, fabrication till prototype stage
and experimentation of the FA100 ultralight water well
drilling rig.
The FA100 drilling rig can drill water wells having
Hmax=100m depth and Dmax=250mm maximum
diameter used for:
1. Potable, washing and irrigation water alimentation,
especially for small households from rural and suburban
communities, just where the water crisis is worst
manifesting in our country today;
2. Installation for Heat Pumps (WATER-WATER
and
SOIL-WATER);
3.Construction
foundations
reinforcement; 4. Geological soil sampling;
5. Mounting of electrical grounding systems.
The casing of the wells is made where is necessary
with PVC VALROM D=140x5.4mm blue casings,
especially made for water wells.
The necessity of making of the FA100 drilling
rig within this NUCLEU program has occurred due
the general objective of the project, which is the
researching for the efficiency of the technological
equipments and processes for using of regenerative
and non conventional energy sources, program which
offers also at the best hand and alternative solutions for
heating using fossil combustibles, through researching
for some regenerative, ecological, non conventional
systems of heating using Heat Pumps, having high energy efficiency, which can not be efficient
implemented only by drilling wells for installation of
the Heat Pumps using drilling rigs like FA100 rig, which
is light weight, efficient, having low fabrication and
exploitation costs but which can drill Hmax=100m
depth water wells with maximum quality of drilling.
One of the main obstacle till now for the
implementation of the heating systems using Heat
Pumps in Romania has been just the lack on the
Romanian market for a light drilling rig which can drill
H=100m wells for installing Heat Pumps at the best
price/quality ratio, as FA100 drilling rig can.

Experiencing the functional model of thermochemical energy
storage facility
Determination of the capacity and yield storage for at least three
systems of material
ABSTRACT
The thermochemical energy storage method is
based on storing/using of thermal effect resulting from
reversible reactions that can occur in various material
systems at specific temperatures / pressures. Basically,
the method allows the use of seasonal heat stored in
a material under specific conditions of temperature /
pressure and its release by exothermic decomposition
reaction or dehydration; the resulted thermal effect
can be used for heating of residential spaces. These
reversible processes can be exploited virtually, using
specially designed equipment. In this project it has
been designed and built a functional facility with a
volume of 15.32 cm3 which has been used to determine
the specific capacity and the yield storage for three
material systems.
INTRODUCTION
The solar energy is an inexhaustible resource that can
be used in thermochemical energy storage applications
as the primary source of energy in the reactions of
dehydration / decomposition of salts.
In the case of residences equipped with solar panels,
solar energy available in summer exceeds domestic
demand for water heating for current needs. However, in
winter, heating demands is higher than those provided
by solar energy. This extra energy required in winter
can be ensured by collecting the solar energy surplus
National projects
generated during the summer through seasonal heat
storage systems. The thermochemical energy storage
is part from this system. There are two constructive
solutions of such equipment, as are shown in the
Figure 1. [1]
Fig. 1. Constructive solutions of thermochemical
energy storage installations
The first solution refers to installation with separated
reactors for the two reactions (Figure 1. a) and the
second solution refers to a single reactor in which
the two reactions take place at specific temperatures,
determined by the ambient temperature (Fig. 1 b).

Using the storage facility shown in Fig. 2 and on the
basis of the scheme presented in Figure 3 hydration /

systems presented in tab. 1, in the following test
conditions:
Reactor heating rate: 0.5°C/min
Pressure: atmospheric pressure
Temperature range: under specific temperatures of
the reversible processes. (Table 1)

Experimental conditions did not ensure full reactions in
the system for all materials tested, one of the reasons
being the quality of active materials available, proven
by DSC thermal analysis performed on the active
materials. For example, in Fig. 4 is shown the DSC
thermal analysis performed on MgSO4.7H2O.
Fig.4. DSC thermal analysis – MgSO4 7H2O
Cumulative reaction enthalpy of the two endothermic
effects observed on the DSC curve is ≈ 515J/g, a
value much lower than that reported in the literature
(1.67kJ/g).
CONCLUSIONS
According to the data from the table 3 is found
that recovery yields achieved on the experimental
model of thermochemical energy storage facility
are systematically lower than the reference models
presented in the literature, which is due on the one
hand to the low ratio of thermal mass of active material
/ overall thermal mass of the installation and to the
quality of the active materials (grain size, degree of
packing texture) at our disposal.

Energy optimization of lightning systems
ABSTRACT
The idea of energy optimization has started from the
fact that artificial lighting represents one of the main
components of human activity, helping to improve
work efficiency. Under the present sub theme, there
were developed several sets of measurements, for
energy optimization, determining the values for: active
power, reactive power, apparent power, effective
values of electric voltage and current, the cosine of
the phase shift angle between the voltage and current
fundamentals, the power factor as well as the lighting
level.
INTRODUCTION
The purpose of this paper consists in the energy
optimization of some lightning systems: incandescent
lamps, high pressure mercury vapours discharge
lamps, high pressure sodium vapours discharge lamps,
fluorescent compact lamps and LED lamps.
The objectives of the execution phase are considering
the determination of the active and reactive power in
accordance with the output luminous flux for various
lightning systems: incandescent lamps, high pressure
mercury vapours discharge lamps, high pressure
sodium vapours discharge lamps, fluorescent compact
lamps and LED lamps, as well as the determination
of luminous flux/power ratio and the lighting systems
energy classification respectively.
The electric lighting represents one of the largest
electricity users, both by its weight in the balance of
power and as an essential element in the development
of the contemporary society.
The primary endpoint of a modern and efficient
lighting system is to provide a luminous comfortable
environment, with a minimum of necessary power and
with minimum investments [1].
The parameters which are appropriate for electric
lighting quality assessment are:
- the lighting level;
- the non-uniformity of illumination;
- the luminance level;
- the light colour;
- the light channelling;
- three-dimensional highlighting;
- level of the stroboscopic effect;
- level of the lighting system’s acoustic noise;
- disturbances on the supplying power grid [1].
Increasing the efficiency of electric lighting reduces
the electricity bill, reduces the energy demand and
thus, reduces the level of environmental pollution by
the used energy.

In order to determine the lighting level, there was
used the PHYSICS Line CA 811 light meter, ARNAUX
CHAUVIN brand.
In order to determine the energy characteristics,
there was used a FLUKE 434 power analyzer, which
meets the conditions established for monitoring the
voltage and electrical current changes, as well as and
the levels of active, reactive and apparent power along
with the power factor and phase angle between the
voltage phasor U and the electric current phasor I .
The measurements have been achieved by multiplying
10 times the electrical conductor clamp of Fluke 434
power analyzer in order to increase its sensitivity, and
accuracy of measurements.
There were achieved several sets of measurements,
determining the values for: active power, reactive
power, apparent power, effective values of electric
voltage and current, the cosine of the phase shift angle
between the voltage and current fundamentals, the
power factor as well as the lighting level.
Under the present sub theme, there was achieved
the energy optimization of some lightning systems:
incandescent lamps, high pressure mercury vapours
discharge lamps, high pressure sodium vapours
discharge lamps, fluorescent compact lamps and LED
lamps.
Table 1. Experimental determination of the electric
parameters for the first tested set of lighting lamps
taking into account the luminous flux - power ratio,
it resulted that the LED lamps have been the most
efficient.
In terms of the harmonics spectrum, the absorbed
electric current has displayed the most distorted
shape of the curve, in the case of compact fluorescent
lamps.
Currently, there have been developed and is indicated
the use of models with improved power factor (named
“lamps with power factor corrector”) with reduced
harmonics problems, but a sensible increased price.
CONCLUSIONS
In order to evaluate the energy efficiency and the
impact on the power supply grid of different types
of lighting lamps, there were determined the values
of: active power, reactive power, apparent power,
effective values of electric voltage and current, the
cosine of the phase shift angle between the voltage
and current fundamentals, the power factor, and well
as their lighting level.
Following the experimental measurements there has
resulted that the maximum energy efficiency has been
obtained in the case of luminescent diodes lamps (over
17 lux/W) and the minimum energy efficiency for the
fluorescent tubular lamps (about 1.3 lux/W). It was
also noticed that, except for the incandescent lamps,
all the other investigated ones generate harmonics, the
harmonic proportion being particularly high (of approx.
90% for the 3rd order) for the lamps with embedded
power supply circuits.

As a result of the experimental measurements, it
appears that the maximum relative level of illumination
is obtained in the case of LED lamps. Thus, for an
absorbed active power equal to 3,22W, the level of
illumination was equal to 44lux. In the case of another
studied configuration, for an active power equal to
5,87W, there was obtained a lighting level equal to 105
lux. Comparing to the other lamps that were tested,

Electrical machines with increased efficiency, by using advanced
technical solutions based on the predetermination of the magnetic
properties of sheets
ABSTRACT
The magnetic properties of electrical steels are
determined by the composition and structure. During
processing, depending on the processing technology,
the composition and structure of electrical steels
may change, leading thus to change their magnetic
properties. Such global magnetic measurements were
made.
It were characterized globally according to IEC
60404-2-1996, Magnetic materials - Methods of
measurement of magnetic properties of electrical steel
sheets, sheet packet type M400-65A.
To analyze the influence of punching on process
energy losses increased length was chosen perimeter
punching by applying successive cuts along the length
of the sample at different widths.
EXPERIMENTAL
Measuring global magnetic properties was carried
out using a closed magnetic circuit. Construction of the
entire device and the magnetizing coils are compliant
with IEC 60404-2-1996, Magnetic materials - Methods
of measurement of magnetic properties of electrical
sheets using the Epstein Brockhaus Messtechnik.
Samples subjected to global magnetic measurements
were cut in the sample sheets with width 30mm, length
300mm, and were arranged in package of 16 pieces
according to IEC 60404-2-1996, Magnetic materials
- Methods of measurement of magnetic properties of
electrical sheet.
Measurements on sheets cut by punching process
INTRODUCTION
Investigation process of magnetization of a
ferromagnetic material can possibly be done on two
levels of description. First, it can be postulated on
the basis of direct observations, a specific domain
structure and predict its behaviour according to the
minimum energy principle. This approach is still able to
actually provide anti hysteresis magnetization curve of
the material [1]. Secondly, the energy can be focused
on the component, the variation due to the interaction
of which with the centres of the fixing Bloch walls by
appropriate statistical description of the domain wall
movement, for tailoring the material coercivity [2, 3].
The aim of this work was to develop a model of
the behaviour of magnetic properties as a result of
processing the sheets type M400, to perform global
magnetic measurements and specimens on samples to
perform papers and to participate in conferences with
members of the consortium.

The test sample consisted of a single piece of size 300
× 30 × 0.65 mm3 (width of the sheet lt = 30 mm).
The test of electrical sheet consisted in the variation of
the magnetic polarization J {1380, 1500, 1800} mT,
measured at the frequency f {10, 20, 30, 40, 50, 60,
70, 80, 90, 100, 200 , 300, 400, 500, 600} Hz.
Variation of energy losses in excess if the 15 mm
width sheet for different magnetic polarization
It can be seen that with increasing magnetic
polarization influence on the length of the perimeter of
punching power losses increase. This is mainly due to
increased hysteresis losses.
National projects
In order to analyze the influence of punching process
of the loss of energy has been chosen to increase
the length of the perimeter of the punching by the
application of successive cuts along the length of the
sample at different widths.
With increasing magnetic polarization influence on
the length of the perimeter of punching power losses
increase. This is mainly due to increased hysteresis
losses.
It is found that with increasing magnetic polarization
peak value and the frequency of measurement appear
larger differences between the losses measured on the
sample 15 mm width, compared with the sample 30
mm width.
Variation of energy losses through hysteresis
determined for samples of different widths for
magnetic polarization Jp = 1800mT
Measurements on sheets cut through the electricerosion process
The test sample consisted of a single piece of size
300 × 30 × 0.65 mm3 (width of the sheet lt = 30
mm). The test of electrical sheet consisted in the
variation of the magnetic polarization J {1600, 1800}
mT, measured at the frequency f {10, 20, 30, 40, 50,
60, 70, 80, 90, 100, 200 , 300, 400, 500, 600} Hz.

CONCLUSION
Have been fully performed all activities and objectives
set out in the phase II (2013) Contract PCCA - CTR.
32/2012.
After modelling the magnetic behaviour of magnetic
sheets processing depending on the way it was found
that stress affected zone length is comparable to the
thickness of the sheet. This has been confirmed by
experimental measurements.
In the study the effect of mechanical processing on
the structure, composition and extent of the sheets
areas affected by the processes done, it was found
that:
1.
Mechanical processing can adversely affect
the losses in electrical steels.
2.
With
increasing
magnetic
polarization
influence on the length of the perimeter of punching
power losses increase. This is mainly due to increased
hysteresis losses.
3.
It is found that with increasing magnetic
polarization peak value and the frequency of
measurement appear larger differences between the
losses measured on the sample 15 mm width compared
with sample 30 mm width.

Literature review regarding energy issues in osmotic processes
Chemical modification of semipermeable membranes type thin film composite and
exchange cation/anion membranes-experimental trials
Experimental trials of 3D nanopatterning on in house polymeric membrane/
conductive substrates by SEM-FEB/AFM methods
ABSTRACT
One of this project objectives is to explore membrane
mechanisms involved in osmotic processes and to
prospect the possibilities to model / execute osmotic
nanodevices by SEM/FIB techniques and chemical
modification of existing FO membranes.
INTRODUCTION
As in an RO process, great demands will be placed
on membrane in most industrial FO processes. A
review of the literature shows that there are some
approaches to membranes for large scale osmotic
(non-RO) concentration processes. One of the them is
to design and fabricate new membranes specifically
for the FO process.
Two of the project objectives is to explore new
possibilities to design and fabricate new membranes for
FO. In this regard during 2013 activities, the experimental
work deal with testing chemical modification of different
types of membranes (Nafion 117, Celgard, PVDF) and
trials on nanolitography techniques. Focussed ion beam
(FIB) patterning is nowadays used on rather large scale
in the microelectronics industry to pattern structures
with lateral sizes down to several tens of nanometers.
Therefore, inorganic membranes with nanopores have
been fabricated using nanolithography techniques.
These processes can precisely control nanopore size
and easily integrate with microdevices. Nanopores
were drilled using techniques of focused ion beam (FIB)
and electron beam lithography (EBL) on substrates,
including silicon1 silicon nitride2, and graphene3.

EXPERIMENTAL
During 2013 activities, have been performed:
1. Testing of several chemical modification methods
on 3 types of membranes:
- Proton exchange membrane: NAFION 117;
- Cation exchange membrane: PVDF (polyvinilpirolidone);
- Anion exchange membrane: CELGARD.
Chemical modification has been achieved by wet
chemistry and sol-gel methods with:
- Conductive polymers: pyrole in case of NAFION
and aniline in case of CELGARD;
- SiO2- case of PVDF;
- CNT (carbon nanotubes) case of NAFION.
2. Trials of nanopatterning on: Si and chemical
modified obtained membranes by focussed ion beam
(FIB) and nanolithography based on atomic force
microscopy.
The above mentioned test membranes (NAFION,
CELGARD, and PVDF) have been successfully chemical
modified.
Celgard microfiltration membrane was functionalized
to enhance anti-poisoning properties through optimising
hydrophilic character by:
- covalent bonding with a macroinitiator based on
peroxide polyelectrolyte (obtained from polypropyleneanhydride (altmaleic) and t-butyl hydroperoxide;
- in situ polyaniline polimerization (chemical
modification was put in evidence by FTIR and AFM
measurements).
NAFION 117 has been modified with:
- Carbon nanotubes addition; CNT quantity in
polymeric matrix influence the performance of
composite membrane used in osmotic processes, in
order to ensure a high penetration flux and excellent
selectivity; used carbon nanotubes has been modified
with polyvinyl alcohol;
- In situ polymerisation of pyrole-to enhance
sensitivity and proton conductivity and CH3OH/H2O
permeability (possible by perm selective polymeric
coatings);
PVDF has been modified by SiO2 nanoparticles; from
literature report appear that increasing silica quantity
in diluted PVDF solution lead to membranes with high
permeation flux and low retention.- comparing with
concentrated PVDF solution where addition of silica
has no influence on membrane performance.
All resulted chemical modified membrane samples
were qualitative analysed in this step – by electron
microscopy and FTIR measurements in order to
partially validate the potential method of chemical

modification ( of selected semipermeable membranes)
from the inside of quick and low cost methods.
The nanopatterning trials had in view testing the
processing availability of chemical modified membranes,
of carbon membranes (based expanded graphite)
and SiO2- by focussed ion beam and atomic force
microscopy nanolithography. In this attempt have been
track the influence of time exposure, beam current and
type of processed material.

From obtained data, were noticed that FIB
patterning results has been optimum (related to
geometric accuracy) at 10 pA and drilling tine of 166s
for carbon membranes and for 10pA and drilling tine
of 417sfor SiO2 samples. Depth penetration has been
kept the same for all samples. Increasing the current
(e.g. 200pA) leads to material co-deposition and stress
of the target material. Decreasing the current (smaller
than 5pA) leads to undefined patterns.
For in house obtained conductive membranes, by
AFM were put in evidence topographies differences
in range of nanometers. Based on critical condition
imposed for AFM patterning substrates has been
abandoned the idea to pattern the obtained conductive
membranes through AFM; due to surface quality or
spatial limitation and processing condition this type of
patterning (AFM nanolithography) become an instable
process and could lead to non-reproducible scale up
methods.
CONCLUSIONS
Chemical modified membranes could be designed
for particular application with special features given
by certain functional-active chemical group grafted on.
Chemical modification on semipermeables membranes
could be applied to improve separation performances
(affinity/selectivity). In this step, the grafting method
National projects
on selected semipermeable membranes has been
successfully achieved.
The nanopatterning trials proved the processing
availability of in house prepared membranes. Various
materials
can be selectively etched in reactive gas
atmospheres achieving aspect ratios up to 30 with a
minimum feature size below 25 nm. Having the unique
nanopatterning ability to add or remove features with
a resolution of 20 nm or better, the FIB method is
currently used to modify integrated circuits and masks,
or to fabricate cross section transmission electron
microscopy specimens. The major drawback of the
method is associated
with the high damage that occurs during milling
and imaging, in particular, if a dual-beam FIB machine
(where imaging is performed by a primary electron
beam) is not available. While most of the structural
defects can be healed by a high-temperature thermal
annealing after milling, a gallium doping is basically
unavoidable and in special cases might be relatively
harmful to the final properties of material.

Concept and design of a biogas reactor 10 m3 volume and flow 350 l/day
ABSTRACT
In the analysis performed on the current national
and European development of biogas technologies to
harness waste to biogas production was elaborated
the design theme for 10m3 biogas reactor to allow
accurate technical conditions to be considered in the
draft implementing 10m3 biogas reactor followed by
3D models of components and finally the assembly
in macro-template based on these 3D models being
developed the execution documentation for 10m3
biogas reactor.
INTRODUCTION
In Romania, biogas production is still a common
practice due to market barriers such as lack of technical
knowledge and experience of farmers, of the designing
companies, general lack of information for decision
makers on economic and environmental benefits of
these technologies, and insufficient access to finance.
In Europe, countries such as Austria, Denmark,
Germany and Sweden are among the most experienced
in terms of biogas technology, they managed to
establish national markets competitive in the field. The
biogas plants by Member leaders in the field are to
treat such waste products from agriculture, and other
fermentable materials (waste from the meat industry,
dairy, spirits), and sludge from wastewater treatment
plants, being designed and built with the aim of waste
by generating energy.
Classification of biogas installations can be done by
many criteria, such as the power mode of the biomass
in the fermenter, fermenting the geometrical shape of
the reactor, the number of reactors used, location on
the ground, working schedule etc.
We can make a classification of the biogas
technology:
•
Anaerobic technologies with continuous flow;
•
Anaerobic technologies with batch operation;
•
Anaerobic technologies lagoon;
•
Vertical anaerobic technologies reactors;
•
Horizontal anaerobic technologies reactors;
•
Single-phase anaerobic technology;
•
Anaerobic technologies biphasic;
•
Anaerobic technologies without mixing;
•
Anaerobic technology with constant stirring;
•
Anaerobic technologies for households.

The design theme was developed and reviewed by
members of the research project and submitted for
approval to the management department in which was
running the project.
Therefore after the analysis of biogas technology
and respecting the data required in the design theme
was designed the biogas reactor shown in Figure 1.

The essential element of a biogas plant is the
digester, a sealed reactor tank air ingress, in which the
raw material is subjected to anaerobic fermentation
process, taking place, thus, biogas production.
It was performed a series of calculations for sizing the
digester wall thickness and for strength of the digester
under pressure, based on these calculations for sizing and
strength was achieved the virtual 3D model of a 10 m3
digester the suitable diameter for application is d= 2000
mm and a length of L = 3500 mm, made from glass
fiber and pipes for supply / discharge are made from PVC
with diameter of 200 mm, having a gas outlet at the top
of tank with diameter of 1200 mm.
The content of the fermentation reactor must be
stirred several times a day, for further mixing fresh raw
material added to existing substrate in the fermenter,
to prevent the formation of crusts on the surface of
the sedimentation layer and, the bringing into contact
of microorganisms with new feedstock particles,
facilitating lifting gas bubbles and the homogenization
of heat and nutrients.
Thus it was designed the 3D virtual model of a
vertical shaft mixer consists of a vertical gear motor
with power P = 0.18 kW (covering) and output speed
n = 35rot/min FF127 R77 DR63 type M4 (SEW
Eurodrive GmbH the manufacturing company) a flexible
coupling for transmitting motion and retrieving game
type KXL - 13.5 - A - A (JAKOB Antriebstechnik GmbH
the manufacturing company) and a sub-assembly
consisting of a mixing propeller with a diameter of ϕ
600 mm and a shaft, vertically arranged, mounted on
the fermentation digester.
For storing biogas fermentation process using buffer
tanks called gasometers. These are necessary in order
to ensure a constant flow of gas to the user. In the
case of this biogas reactor from the project, with a
small amount of gas produced, shall be chosen the
gasometer with constant pressure and variable volume,
the solution with water tank and hydraulic closing.
For feeding / discharge frequently, are used two
types of pumps: centrifugal pumps and displacement
pumps. Centrifugal pumps (rotary) are, most often,
submerged, however they can be placed next to
the digester in a dry well. For special applications
are available fragmentation pumps that are used for
materials containing long fibers (straw, fodder, grass
cuttings).
Knowing the volume of 10 m3 biogas plant and
product gas flow 350l/day according to the daily
production of biogas ensure 350l/day was chosen
and selected according to these criteria a pump for
transporting the organic matter to ensure that the
power plant discharge flow required a daily batch type
Sewatec F 150-315 (manufacturer KSB) P = 1.5 kW.
In order for biogas production process to achieve
the optimum parameters imposed, and that the gas
will not be removed accidentally, forced through pumps
and increased safety were chosen according to DN
150 nominal output / input of the pump and the pump
pressure has chosen type valves DN150 PN16 BOA
(manufacturer KSB).
Based on calculations and analyzes three-dimensional
modelling was done for biogas reactor components and
its assembly, finally resulting the virtual model of the
assembly of 10m3 biogas plant shown in figure 2.

Environment
Device for CO2 detection and retention
ABSTRACT
The environment aspects has a major relevance
taking into account the sustainable development and
the long term assurance of appropriate life and work
conditions.
The following aspects have been analysed in this
project:
- wastes generated by the oil industry as well as
their impact on the economy and environment;
- the environmental legislation;
- an analysis of environmental factors: water, air,
soil, presenting the main quality indicators and the allowed limits, specific pollutants and the regulations
regarding the evaluation/ measurement methods.
INTRODUCTION
In the current economic context marked by globalization
and highly recognition of the interdependence
between environment and development, we assist at
the increasing of environmental protection demands
materialized in more severe regulations.
The overall objective of the project „Device for
CO2 detection and retention” is an analysis of the
environmental factors, industrial pollutants and
innovative technical solutions to retain and treat
anthropogenic emissions and wastes.
Two objectives were approached during the stage
no.1/2013 named Methods and mechanisms to reduce
pollution and to remedy oil contaminated areas in oil
and gas industry. Creating a mobile entity to monitor
environmental factors (water, air, soil):
- O1 Identification of wastes resulted from the oilfield
industry;
- O2 An analysis of legislation and specific
requirements regarding the environmental
factors evaluation.
The Romanian environmental legislation is wide and
subjected to a process of continuous renewal, updating,
to correlate with the international requirements,
regulations and standards, particularly with those of
the E.U.
The
E.U.
policy
regarding
the
waste
management
is
specified
in
the
European Community Strategy for Waste Management,
based on three main principles:
- waste prevention;
- recycling and reusing;
- safely final disposal.

Eng. Aurelian Filip, CS
The first objective of the project has as result an
analysis of the wastes generated in oilfield industry
and their impact on the economy and environment,
as well as their regulation – European and national
legislation.
The paper presents the following:
- the National Strategy for Waste Management –
2014-2020 [1], establishing the Romanian policy and
strategic objectives regarding waste management;
- a summary of the current legislation regarding
industrial wastes, both European and national;
- the amounts of hazardous and non-hazardous
wastes generated by the main economic activities
during 2006–2010 [2];
- oilfield industry specific wastes divided into
categories of activities: drilling, extraction and
refining.
Waste legislation strategic elaborated by the
European Directives is transposed in Romania by
laws, Government Decisions and Ministerial Orders
presented in this paper associated with relevant
European legislation.
This paper presents the requirements regarding
wastes producers and holders, as follows:
- wastes records, hazardous wastes included;
- wastes treatment prior to complete elimination;
- controlled storage of wastes so as to not affect
the environment;
- measures to prevent and reduce the quantities of
wastes.
Besides of the main products, a number of residues
(wastes) results as a result of the activities in oilfield
industry, from drilling, extraction, but especially in the
refining and petrochemical.
The most significant residues both quantitatively and
qualitatively, which results from wells drilling strongly
influencing the soil, subsoil, surface and subsurface
waters pollution, are the following:
a) drilling fluid;
b) detritus;
c) gases in drilling fluid;
d) waste water;
e) technological wastes;
National projects
f) chemical products from mud preparation and
wells stimulation.
The most significant residues resulting from oil
extraction are the following:
a) residues from oil separation and storage tanks;
b) slurries;
c) waste water;
d) contaminated soil;
e) decommissioning / construction / demolition
debris.
Oil refinery wastes [3] normally covers three
categories of materials:
a) sludge, both oily (e.g. tanks bottoms) and nonoily (e.g. from waste water treatment facilities);
b) other refinery wastes, including miscellaneous
liquid, semi-liquid or solid wastes (e.g. contaminated
soil, spent catalysts from conversion processes, oily
wastes, incinerator ash, spent caustic, spent clay,
spent chemicals, acid tar) and;
c) non-refining wastes, e.g. domestic, demolition
and construction.
Fig. 1. Oil refinery waste classification [3]
The paper presents the most important characteristics
of these industrial wastes, how they are generated as
well as the risks induced by their mismanagement. From the foregoing results the great diversity
of oilfield industry wastes mostly classified as
hazardous and that needed to be managed (recovered
/ neutralized)
The following aspects were studied within the
second objective:
- interpretation of the terms as ˝environment˝ and
˝pollution˝, resulting that the environment protection
can be defined as an aware and scientifically grounded human activity aiming the pollution prevention, life
conditions maintaining and improving;
- a pollution classification according to several
criteria: provenience, nature and physical condition of
the pollutants;
- the characteristics of each environment element
(water, air, soil), specific pollutants particularly of the
oilfield industry as well as aspects generated by the
noise pollution;
- environmental legislation containing the framework
legislation, environment elements legislation (water, air,
soil, noise level) and a summarization of the European
Directives transposed/implemented by Romanian
laws;
- environment elements (water, air, soil, noise level),
presenting the main pollutants and pollution sources,
the quality indicators and their allowed limits as well
as the regulation regarding evaluation / measurement
methods.
The second objective also includes a summarization
of current environmental legislation and of the
environment elements quality requirements for all
those interested.
CONCLUSIONS
Analysing the petroleum industry technological
processes generating wastes, it can be concluded that
the waste generation can not be stopped. However, the
wastes producers have the legal obligation to properly
manage these wastes under strictly supervised
conditions in terms of the environment quality and
protection and of the human safety and health.
Multiple benefits are obtained from petroleum
wastes recovery by using them in different industries
as substitutes of traditional fuels and raw materials,
saving non-renewable resources and solving waste
management problems in this industry. This paper
could be continued by identification of wastes
treatment methods in order to reduce the content of
organic compounds and the mobility of the potentially
pollutant inorganic compounds, supporting all the
petroleum wastes producers. This paper shows that the environmental Romanian
legislation is wide, containing many Government
Decisions, laws and orders issued by different
authorities. This paper summarized them, supporting
all those interested in current environmental legislation
and quality requirements of the environment
elements. It shows that Romania has fulfilled its
obligations assumed by signing the Accession Treaty
to the EU, harmonizing its legislation, particularly the
environmental legislation, with EU legislation.

Modelling and procedures for the preparation of the manufacturing,
assembling and testing processes of the magnets for FAIR project
ABSTRACT
In order to create the 3D model of the magnets
that are subject to the in-kind contribution to the
FAIR project and in order to elaborate the assembling
procedures of these magnets, there have been created
the 3D models of all the components, subassemblies
and overall assemblies for the sextupole, horizontal
steerer and vertical steerer magnets, there have been
elaborated the procedures for the assembling of
these three magnets and there have been identified
and analyzed the errors specific for the harmonic coil
measurement method of the field inside the aperture
of the magnets.
INTRODUCTION
The FAIR - Facility for Antiproton and Ion Research
it’s an international project which will set up in
Darmstadt, Germany, a system of particle accelerators
which will provide to scientists the possibility to
conduct cutting-edge research in the nuclear physic
field. The participation of our country to this project
started in 2010, when the FAIR GmbH was created,
Romania being a signatory part to the FAIR Convention
and Shareholder to FAIR GmbH. The major part of the
Romanian in-kind contribution to the FAIR project,
meaning almost 4 millions €, consists of equipments
which will be integrated in a FAIR sub-project, will be
provided by ICPE-CA.
To set up this very important contribution, ICPE-CA
initiated, since 2007, preparatory activities for the
participation in the FAIR project, activities which
leads to the integration of our institute in the HESR
consortium, created to develop the HESR - High Energy
Storage Ring, important part of the FAIR project.
A team of researchers have been created in ICPE-CA
to work together with the foreign specialists for the
preparation of the fulfilment of the HESR project
objectives. This team include specialists from various
fields, like CAD, electromagnetic design and simulation,
mechanical, electrical and magnetic measurements,
materials, machining, and technology. Until now there
were developed the prototypes of two magnets, one
sextupole magnet and one steerer magnet.
For a proper preparation of the fabrication of the
magnets that are subject of the in-kind contribution
to the FAIR project there have been created the 3D
models of the sextupole, horizontal steerer and vertical
steerer, models that will be used to elaborate the 2D
manufacturing documentation.

The necessity of designing and modelling a new solution
for the steerer magnet, which has to be compliant to
the available manufacturing technology, has to ensure
the adjustment of the coils to the new position of
the connecting systems and has to comply with the
imposed parameters, have required to redesign the
steerer mechanical structure and the coils terminals,
in order to adjust them to the new site of the electrical
and hydraulic connecting systems.
The 3D models of the vertical steerer magnet are
shown in figure 1 and the 3D models of the horizontal
steerer magnet are shown in figure 2.
Fig. 1. Vertical steerer coils
Fig. 2. Horizontal steerer coils
National projects
Then it was preceded to the creation of the sextupole
magnet 3D model. For this purpose there have been
created the 3D models of all the components of the
magnet, which have been virtual assembled, in order
to create the sub-assemblies and the final assembly,
shown in the figure 3.
Fig. 3. Sextupole magnet
In a similar way, there have been created the 3D
models for the horizontal steerer magnet and for the
vertical steerer magnet. Their 3D models are shown in
figure 4 and figure 5.
Fig. 4. Horizontal steerer magnet
Fig. 5. Vertical steerer magnet
On the basis of the manufacturing documentation
for the sextupole magnet and in conformity with the
magnet specifications there have been elaborated
the procedures for the assembling of the sextupole,
horizontal steerer and vertical steerer magnets [2].
To prepare the testing activity which will be carried
on in order to check the compliance of the magnets
with the specifications, there have been made an
analysis of the effect of the errors of the harmonic coil
measurement method in the process of determination
of the magnetic field inside the aperture of the magnets,
method which have been developed previously.
The errors specific to the harmonic coil measurement
method are errors due to the harmonic coil manufacturing
process, errors due to the positioning and displacement
of the coils inside the magnets aperture and errors due
to the measurement environment and equipment [3].
It is established that these errors are not systematic
and can be eliminated only partial thru repeated
calibrations.
CONCLUSIONS
The main conclusions of the performed activities
are:
-
the solution adopted for the steerer magnet
coils comply with the request for having access to the
connexion between the coils parts, avoiding difficulties
that arise if cooling water leaks occurs in the connexion
region;
-
the 3D models created for the steerer magnet
coils allowed to check the solution for the assembly,
from the point of view of coils adjustment to the
electric and hydraulic connexion systems;
-
the solutions adopted for the parts, subassemblies and overall assemblies of the sextupole,
horizontal steerer and vertical steerer magnets comply
thoroughly the requests imposed for the dimensions,
tolerances, materials, aspect etc.;
-
the 3D models creation followed with
high accuracy the technology for manufacturing
and assembling, so it can be use to elaborate the
manufacturing and assembling procedures;
-
the created models include detailed information
regarding the materials used for magnet’s components
manufacturing, so it allows to get very fast and easy
useful information for the manufacturing process
preparation: weight of the parts, moments of inertia,
centre of mass, volumes, aspect, colours for painting
and others;
-
the assembling procedures elaborated include
all the information necessary for a proper mounting of
the magnets;
-
for the sextupole magnet, the field from his
aperture can be calculated with a tolerable accuracy
taking into account only the third harmonic, the most
important one;
-
for the horizontal steerer magnet, the field
from his aperture can be calculated with a tolerable
accuracy taking into account only the first harmonic,
the most important one;
National projects
-
for the vertical steerer magnet, the field from
his aperture can be calculated with a tolerable accuracy
taking into account only the first harmonic, the most
important one;
-
the values of the field, calculated with the
analytical method, have a relative sensitivity less than
one in respect to the boundary conditions.

A new low voltage contactor with vacuum commutation, of compact type
ABSTRACT
The overall objective of the project is to design and
produce a series of low-voltage contactors with vacuum
commutation with rated current of 200A, 315A,
400A and 630A, with small size which can be fitted
in place of the classical electromagnetic contactors
(with commutation in air) of 200A. The achievement
of the general objective is possible through synergistic
collaboration between four (4) partners (ICPE SA,
INOE 2000, INCDIE ICPE‑CA, MEDAPTECH SRL)
with experience in the field, under the coordination of
UPB‑CCSA (CO).
The role of INCDIE ICPE‑CA is to conduct research
in the field of the obtaining of vacuum contact parts
with superior functional characteristics, coupled with
the miniaturization of the commutation devices, in
compliance with the environmental protection.
INTRODUCTION
In general, the requirements for the contact parts of
the commutation devices used in vacuum (switches,
contactors), such as erosion resistance, low tendency
to welding, high electrical and thermal conductivity
and high hardness, are dependent on the method of
manufacture (infiltration, sintering) and can only be
achieved if the contact material has a fine-grained and
homogeneous microstructure [1-4].
In the research work from Stage I/2012, experimental
models of vacuum contact parts were realized by
infiltration method, based on W-Cu composite materials,
with and without addition of Ni or Ag, having relative
density: 95.25 ... 96.83%, porosity: 3.17 ... 4.75%,
electrical resistivity: 3.12 ... 6.15 µΩ·cm, Vickers
microhardness HV0,3/15: 212.7 ... 260.9 and average
values of chopped currents: 2.84 ... 3.66 A [5].
Unlike the process of sintering, by using the infiltration
process is difficult to obtain fixed compositions,
these varying within certain limits, which leads to the
obtaining of different characteristics.
A modern method for manufacture of the vacuum
contact pieces with superior functional performance is
spark plasma sintering technique (SPS), which allows
the obtaining of any composition, densities closer to
the theoretical density and microstructures that retain
the original properties of the components [6 -10].
The researches purpose in the Stage II/2013,
consisted of making a mould and vacuum contact parts
from W-Cu-(Ni) and W/WC-Ag systems by using this
mould, with SPS technique, and the characterization
of the obtained contact parts, in terms of physical
properties, structural, electrical, mechanical and
functional.

For reaching these proposed objectives in 2013, the
following experiments were performed:
• It was conceived, designed and developed a
functional model (MF) of a mould to obtain the vacuum
contact parts of 20 mm in diameter and 4 ... 5 mm in
height, by SPS technique;
• There were performed 18 MF of vacuum contact
parts by SPS technique, from W-Cu-(Ni) and W/WC-Ag
systems;
• There were characterized the MF vacuum
contact parts in terms of physical properties (density,
residual porosity, degree of compactness, Vickers
microhardness), electrical (conductivity and electrical
resistivity), microstructural, mechanical (modulus of
elasticity) and functional (chopped current).
REZULTS AND DISCUSSIONS
•
It was conceived, designed and manufactured
a special graphite mould from IBIDEN material of T-10
class (Fig. 1), specific for hot pressing applications, in
order to obtain contact parts of 20 mm in diameter and
4 ... 5 mm in height, at the SPS installation of HP SPS
D 25 type (FCT System GmbH, Germany).

•
There were characterized MF from the
systems of W-Cu-Ni, W-Cu, W-Ag, WC- Ag, in regard
to the microstructure characteristics. Generally,
depending on the chemical composition and SPS
processing parameters, there were found homogeneous
microstructures without structural failure, with a certain
degree of dispersion of the particles of W/WC in the
matrix and a certain degree of porosity. For instance,
from the structural characterization of MF from WCAg, the most homogeneous microstructure with a fine
distribution of WC particles (≤ 2μm) and low porosity
were obtained for the WC-30%Ag and WC 40% Ag
(Fig. 3), sintered at 940oC/5 min, and 930oC/5min
respectively.
•
There were characterized the elemental
powders and the contact materials elaborated from
homogeneous mixtures of W-Cu-(Ni) and W/WCAg powders composites, in terms of morphological

•
There were analyzed the physical, mechanical,
electrical and functional characteristics of the obtained
MF, ascertaining the following:
- for the W-Cu-Ni (85-14-1 and 85-12-3) contact
parts, the highest degree of compactness (97.97%)
and thus, the lowest porosity (2.03%) and also, the
higher Vickers hardness (446.24 HV) and Young’s
modulus (GPa 214.50) values were obtained for the
W-Cu-Ni (85-12-3) parts sintered at 1200oC, that
showed homogeneous microstructures and a high
degree of grain finishing; low electrical resistivity
values (8-11μΩxcm) could be due to the existence of
intermetallic compounds formed during MA; both
Cu-Ni-W contact materials, processed by the SPS at
1100°C and 1200°C, exhibited very good results at
functional testing, yielding to a mean value of the
chopped current of 2.29 A; with Cu content decreasing
and Ni content increasing, the mean chopped current
increased from 0.99-1.73 A to 1.77-2.29 A; the lowest
value (0.99 A) resulted for the W-Cu-Ni part with the
finest granulation;
- for the W-Cu (70-30 and 60-40) contact parts,
at the highest sintering temperature (1050oC), it
was obtained the greatest degree of compactness
(96.41% and 97.05% respectively) for both studied
compositions, due to increase of Cu diffusion into
matrix near the melting point (1083oC); increasing of Cu
content from 30% to 40% resulted in the increase of
the electrical conductivity and therefore, in decreasing
of the electrical resistivity, the lowest values being
recorded for the MF with maximum compactness; the
lowest values of the chopped current were obtained
for the MF from W-Cu sintered by SPS at an average
temperature (1000oC) with a maintaining time of 5
min., having the most homogeneous structures; for
these MF, it was also obtained the highest values of
the Vickers hardness and Young’s modulus because of
the uniform and fine distribution of the W particles
into matrix. From the W-Cu system, the best results in
terms of physical, mechanical, electrical and functional
characteristics, has been achieved for the MF from
W-Cu (70-30), vacuum sintered by SPS at 1000oC,
with a maintaining time of 5 minutes.
- for the W-Ag (70-30 and 60-40) contact parts, the
best densification (91.67% and 96.11% respectively)
was obtained for the MF with homogeneous structures,
sintered at the highest temperature (930°C-940°C),
in the vicinity of the melting point of Ag (960oC);
increasing of Ag content from 30 to 40% led to increase
of electrical resistivity values from 3.92 µΩxcm to
2.70 µΩxcm; the highest values of Vickers hardness
(136.25 HV) and of the elasticity module (141.32 GPa)
were obtained for the MF with the highest Ag content
(40%), which had homogeneous structures and a high
degree of compactness.
- among WC-Ag (70-30, 60-40) contact parts, the
WC-40%Ag parts sintered by SPS at 930oC/5min
showed the greatest degree of compactness (95.23%)
and therefore, the lowest porosity (4.77%), the highest
values of Vickers hardness (223.10 HV), the highest
values of Young’s modulus (185.06 GPa) and the
lowest values of electrical resistivity (4.65 µΩxcm); at
the functional testing of WC‑Ag (60-40) pair, after 31
measurements performed at a injected current of 25 A,
there were obtained the lowest values for minimum and
maximum chopped currents and standard deviation:
Imedium = 0.59 A; Imax = 1.03 A, standard deviation:
0.19.

ABSTRACT
In the frame of the research project, were performed
measurements for time attenuation of electrical charge
on the textiles samples using a testing stand projected
and realized in MNE Department in accord with standard
profile SR EN 1149-3: 2004, part 3. The measured and

electric charge and protection coefficient.
INTRODUCTION
Conductive textiles materials and the textiles based
composites were used as antistatic garments with
applications in electronic industry, in medium with
potential explosive and defence, because in particular
of their electrostatic properties. [1]. Many synthetic
fibers used in manufacturing of textiles were the
insulation materials with resistivities in order 1015Ω.cm;
this value is much too large for this textiles to be used
like antistatic materials, such as, for this application the
textiles must have the resistivities values in the range of
109‑1013Ω.cm [1, 2]. For conductive fabrics realization,
on proceed to the special treatment of fibers, for
example, the textiles fibers coating or filling the textile
fibers with metal salts [1]. The aim of research stage
consists in conducting trials of discharge of electric
charge on the conductive fabrics, the analysis and
interpretation of experimental obtained data. Research staff of the project

Flammable and toxic gas detector based on MOS sensor array on silicon carbide (SIC GAS)
ABSTRACT
There is a great need for flammable and toxic gas
micro-sensors for environmental control in many areas
of industry. Some applications require sensors that can
operate at high temperatures even in reactive chemical
environments.
In the frame of the project, MOS capacitive
sensor of (SiC) silicon carbide that can detect toxic
and flammable gases from the environment will be
researched and developed.
In phase 2 of the project has been researched
and made different experiments of nanometer oxide
layers, sensing element of the structure metal / oxide
/ SiC and different experiments multilayer structures
M / O for the experimental model M / O /SiC. INTRODUCTION
Working at high temperatures in industrial installations
and eliminating some gases with temperatures above
2000C, lead to increasing researches in the last
decade for gas sensors with the possibility of leakage
detection at temperatures above 2000C. The MOS
capacitive sensors on SiC appeared in literature in
1993 [1]. This type of the sensors showed a high
National projects
sensitivity on hydrogen and hydrocarbons detection up
to temperatures of 10000C [2]. Baranzahi has studied
the sensitivity to hydrogen of Pt/TaSix/SiO2/6H-SiC
capacitors at temperatures higher than 6500C, while
Tobias has investigated the same domain with Pt/TaSix/
SiO2/4H-SiC structure [3,4]. On the other hand, Ghosh
analyzed Pt/SiO2/SiC capacitors at the temperature
of 5270C in environments with oxygen or hydrogen
[5]. Saman has studied MOS capacitors on Pt/AlN/
SiC. The results showed that the highest sensitivity of
these devices was obtained for hydrogen [6].
CI Harris has detected CxHy gases using MOS
capacitors with SiC semiconductor and Pt metallic
electrode [7]. MOS structure on Pt/ZnO/SiC detected
H2 and O2 at temperatures up to 3300C [8]. The
project’s objective is to realize a MOS capacitive sensor
of silicon carbide (SiC) for the detection of toxic and
flammable gases from the environment. This type of
sensor is well suited for such applications because it
has selectivity and sensitivity, a fast response, and the
recovery time is short with low power consumption.
The usage of silicon carbide is a key element that
enables the sensor to operate at high temperatures.

EXPERIMENTAL
The insulator oxide in the MOS structure from Phase
2 is silica and/or titanium oxide. In order to attain the
MOS structures sensitive to small amounts of toxic
gases, low thicknesses (not more than 50 nm) are
used for oxides.
Thus, the main problem of this phase is to obtain
different thicknesses of the oxides in a controlled and
reproducible manner.
Researches have been made both on silicon (Si)
wafers, where there is know-how regarding the
oxidation processes, and on silicon carbide (SiC), the
latter being a material for which the partner institutes
have no prior experience.
In the case of SiC wafers the growth process of the
oxide is much slower than in the case of Si wafers due
to the strong links between Si and C.
Therefore, the breakage of these bonds was carried
out through treatment in dry oxygen at 1100°C for 6
hours.
The oxidation was followed by a thermal treatment
in an inert nitrogen atmosphere. A thickness of 30 nm
was achieved for SiO2 on SiC wafers.
To obtain titanium oxide (TiO2), Si wafers were
used on which were deposited thin films of titanium
(Ti) with a thickness of 25 nm by vacuum evaporation
(E-BEAM).
The wafers were oxidized at 6000C for 3 hours and
the obtained titanium oxide has a thickness of approx.
40 nm.
The metal in the structure of MOS sensor is a
catalytic metal; in this stage, experiments were carried
out in order to obtain thin films of nickel and palladium.
At the metal-oxide interface the adsorbed gas molecules
are polarized creating a bipolar layer.
This bipolar layer decreases the work function of the
metal, which reduces the flat band voltage of the MOS
capacitor. The change of the flat band voltage causes
a shift of the CV characteristic of the capacitor.
For experiments, thin films of Ni and Pd and multilayer
metal/oxide: Si/TiO2/Ni, Si/TiO2/Pd; Si/SiO2/TiO2/Pd
was attained using the “High vacuum equipment ATC
2200 INTERNATIONAL AJA” with the DC sputtering
method.
In order to electrically characterize the MOS
structures, all metal depositions were made through a
metallic mask made of brass having a thickness of 0,5
mm and Φ=50 mm, in which were made holes with
diameters of 0,7 mm 0,9 mm and 1,6 mm using the
KERN Micro equipment.
The depositions of Ni or Pd were performed on the
previously deposited TiO2 and SiO2/TiO2 layers.

and the capacities measured on the devices.

CONCLUSIONS
• Experiments were made in order to achieve thin
layers of SiO2 and TiO2 and SiO2/TiO2 bi-layers forming
the dielectric layer in the capacitive MOS sensor using
three methods:
- SiO2 layers were made by oxidation of the Si wafers
at 10000C for 10-20 min.; SiC wafers were oxidized at
11000C/6 hours.
- TiO2 layers were made by RF sputtering;
- The SiO2/TiO2 bi-layers were achieved by oxidation
of the Si wafers at 10000C for 10-20 min. followed
by the E-Beam deposition of Ti and oxidation of Ti at
6000C for 3 hours.
• Thin metallic films of Ni and Pd and Si/TiO2/
Ni, Si/TiO2/Pd, Si/SiO2/TiO2/Pd multilayer metal/oxide
structures were made for the MOS sensor in the form
of dots with Φ=0.7…0.9 and 1.6 mm.
• The measured C-V curves are characteristic for a
MOS capacitor.

EXPERIMENTAL
During experiments for manufacturing SiC Schottky
diodes, thin layers of Ni and Ni/SiO2 on SiC were
deposited by DC Sputtering.
In advance a silicon oxide layer, with a thickness of
650 nm, was thermally grown and on this structure
was deposited a thin layer of nickel. The deposited Ni
structures were processed at different temperatures, in
an argon atmosphere of 99,999%, in situ and ex-situ.

After the investigation of the materials and the
technologies for mounting a diode in the capsule
followed high-temperature experiments for achieving
the conductive adhesive of type nano-sized silver
paste.
Nano silver paste was made of nano-sized silver
powder synthesized at this stage by using polymer
binder and other organics (dispersant, solvent) [7-10].
The microphysical information obtained from the
study of Ni/SiO2 metal -oxide bilayers are important in
determining the technology for the temperature sensor
on the silicon carbide Schottky diode (SiC); it has been
found that the deposition on the substrate heated to
200°C and 400° C is not causing changes in the Ni/
SiO2 structure (Fig.1, Fig.2, Fig. 3). Ni is crystalline
(face centred cubic) (2θ= 44.7° and 52.2°). After
treatment, the nickel crystallite size increases and
the intensity peaks are much larger which shows the
crystal structure.

After heat treatment at 800°C, most of the nickel

with sizes 40-67.8 nm and nickel oxide crystalline
(monoclinic) with sizes of 32-33 nm, which is not

Magnetic nanofluids and magnetisable fluids as nano- microcomposites with high magnetisation: Applications in rotating
sealing at high pressures and hard working conditions and in control
magnetorheologic devices
ABSTRACT
In this step of project the testing of some new
prepared magnetic liquids. Gamma irradiation was
applied for the induction of oxidation under accelerated
conditions. These magnetic systems are foreseen to be
applied for the sealing in pressure circuits of nuclear
power stations.
INTRODUCTION
Magnetic liquids are the sealing systems, which
ensure the good functionality of pressure circuits
in nuclear power stations. For this purpose, the
radiochemical testing is required. These colloidal
products were gamma irradiated, because the
penetration of these rays causes oxidative degradation
of organic layers. The worsening of oxidation state leads
to the modification of particle distribution in magnetic
liquids and the sealing efficiency is affected.

EXPERIMENTAL
The study on thermal and radiation stability of nonpolar magnetic nanofluids (stabilised mono-layer by
chemosorption) or polar magnetic nanofluids (stabilised
double-layer by chemosorption) was accomplished. It
revealed the structural modifications in the organic
phase. The chemical stability of FMR components was
investigated by non-isothermal chemiluminescence
(CL – LUMIPOL 3 – Slovakia) and by differential
scanning calorimetry (Setaram DSC 131 Evo, Setaram
Instrumentation, France). The irradiation was performed
in the machine Gammator provided with gamma source
(137Cs) at a dose rate of 0.4 kGy.h-1.
The investigations by the application of nonisothermal
chemiluminescence have revealed the susceptibility of
magnetic liquid samples to oxidation. The dependences
of CL intensities on temperature are presented in fig.
1. These samples contain also iron nanopowder.
For the analysis of CL spectra the main aspect is
related to the chemical nature of colloidal environment,
which is affected by the action of radiation. Other
main aspect is related to the number of layers which
were chemisorbed on magnetite particles. The
relative distribution of curves is influenced by the
preparation procedure of samples, which determined
the rate of oxidation in the outer layer. The nature of
radicals appeared by the scission on the molecules of
surfactants and their concentrations influence the rate
of ageing that is a self-chain process.
The samples which were prepared by covering
magnetite nanoparticles with double chemisorbed
layers, the problem of stability of polyisobuthylene
succinic aldehyde (PIBSA) is solved by the application
of this layer on the first leaf. This procedure gives the
protection of PIBSA, which is degraded very easy under
gamma radiation. In fig. 1 the CL spectra of various
magnetic liquid samples are presented.
Fig. 1. Nonisothermal CL spectra recorded on
irradiated magnetic liquid samples (series 130214)
The magnetic liquid samples belonging to FMC series
illustrated in fig. 2 have incorporated iron nanopowder.
From these spectra several essential features can be
remarked:
1. sample P5 is affected by irradiation even at 10
kGy, and the evolution for the other irradiation doses
proceeds normally;
2. sample P4 shows the CL curves with the lowest
National projects
difference between themselves. This fact is an
argument for the selection to the industrial production
destined to nuclear applications,
3. the most proper magnetic liquids for foreseen
applications are P2, P3 and P4 because the variation
in CL intensities are the lowest ones,
4. the thermal stability of studied magnetic fluids
can be characterized by the start of oxidation, which
values of time are listed in Table 1.
The values for the start of oxidation represent the
main criterion for the selection of magnetic liquids
destined to seal the power circuits of nuclear power
stations. Their behaviour is influenced by the ratio of
magnetite and iron powder, whose values determine
the initiation of degradation. The particles of iron are
the centres of initiation for oxidation, because they are
the transient species.

Due to the protection offered by outer layers, the
particle covering are much resistant in the radiation
field. This oxidation prevention is based on the
interaction between various hydrocarbon radicals,
which is detrimental for oxidation.

CONCLUSION
Radio-oxidative degradation of magnetic liquids, which
were prepared by the project co-coordinator, pointed
out the relevant influence of chemisorbed surfactants
and the sequence of layers. Even though the start
of oxidation for polyisobuthylene succinic aldehyde
(PIBSA) was recorded at 120oC, this difficulty is
overcome by the fact that PIBSA is an inner layer and
it is protected by outer layer radicals.

Advanced composite structures for aerospace applications
Abstract
The general objective of the project involves
the development and testing of the mechanical
structure of the box that houses the electronics in a
microsatellite, made of composite materials, durable,
lighter, integrating control systems for resistance to
thermal cycles during the operation. At this stage it
was intended to establish the general requirements and
the design of operating conditions in space of the box
that houses the electronics in microsatellites having as
reference the aluminium box currently used.
INTRODUCTION
The development of composite materials in the last
century has become the basis for many technical and
economic considerations, among which: the need for
materials with special properties (less weight, strength
and stiffness, unattainable with traditional materials),
the need to increase safety and operational reliability,
the need to reduce consumption of scarce or precious
materials, the opportunity to reduce labour consumption
and reduce manufacturing technology durations. In the
space industry are numerous stringent requirements
imposed by the design of spacecraft structures. Satellites
must be light and stiff enough to maintain precision
alignment of the measuring / control instruments in
severe space conditions. As a result of cost reduction
trends recorded in aerospace engineering, the use of
uncertified electronics for use in space became a common
practice [1, 2, 3]. The ionizing particles characteristic
for space and severe environmental conditions could
damage electronic devices unprotected to radiation and
may affect the main functions of the satellites [4]. A
structure to house the electronic components should
attenuate the incident radiation and equipping devices
operating in space with such a structure should provide
them a satisfactory protection.
Traditionally, these structures housing the electronics
devices are made of aluminium. In the context of the these
premises, at this stage, the project aimed to establish
general requirements of the box that houses electronics
in a microsatellite based on existing standards for such
spatial structure, based on data existent in the literature
and based on own expertise and propose constructive
alternatives for this by establishing a CAD model.

Low-altitude LEO orbit (LEO - Low Earth Orbit) is
of interest for this study. LEO is defined for altitudes
between 150 and 2000 km above the earth’s surface.
Orbit LEO is characterized by: very low pressure (high
vacuum), extreme temperatures (depending on the
orientation of the material from the sun, heat cycles),
electromagnetic radiation, exposure to various atomic
species and loaded particles (at various concentrations
depending on the altitude and solar activity), the
impact with micrometeorites and fragments of space
(space debris).
The characteristics of the LEO space environment can
be simulated experimentally as follows:
• Ultra-advanced vacuum (~10-6 Torr);
• UV radiations (<200 nm);
• Thermal cycles (-70 ÷ +100 ° C);
• Exposure to oxygen (AO - flux = 4.5x10-16
atoms/cm2s).
Table 1 shows the set of requirements for the box that
houses the electronics in microsatellite reported to the
aluminium reference.

CONCLUSIONS
Generating an optimal design methodology for
composite structure (space housing type) and its
application to optimize weight are important. Design
methodology proposed in the project will includes
constraints on radiation attenuation, natural frequency
of vibration, structural integrity, electrical resistivity
and limiting distortions of form generated by thermal
loads (thermal cycles).

Complex characterization of collagen-based materials, using the
methods of thermal analysis and other advanced techniques
ABSTRACT
In this stage of the project the first TG/DTG/DSC/
FTIR measurements of some parchments and leathers
were performed, both in inert and oxidative atmosphere,
which put in evidence the molecular species that evolve
on thermal decomposition. The effects of temperature
and humidity on the denaturation behaviour of
parchments and leathers both in water and in dry
state were investigated, by performing accelerated
ageing tests. The influence of some factors such as
acids, bases, inorganic salts of alkaline and transitional
metals, pressure etc., on the denaturation behaviour of
these collagen-based materials in water or in dry state
was studied.
INTRODUCTION
Collagen and collagen-based materials were
characterized through numerous thermal analysis
techniques [1-5]. Evolution of gaseous products
resulted from thermal decomposition/pyroliysis of some
collagen-based materials was studied mainly by mass
spectrometry [6-9]. However no similar TG–FTIR study
has yet been reported for parchments or leathers.
Concerning the influence of temperature and
relative humidity on these materials, Badea et al. [10]
reported an extensive micro DSC study on a large
number of parchments, concerning the effects on
hydrothermal stability of these materials. Changes in
collagen thermal stability, increase of heterogeneity
and structural disorder and the loss of fibrillar structure
were observed under the accelerated ageing conditions
used.
So far, to our knowledge, no similar systematic
DMA studies that investigate the effects of artificial
ageing on denaturation behaviour of parchments and
vegetable-tanned leathers while immersed and heated
in water are reported.
Also, there appears to be no studies regarding
the influence of some factors such as acids, bases,
inorganic salts of alkaline and transitional metals,
pressure, etc., on the denaturation behaviour in water
or in dry state.

EXPERIMENTAL
Sorts of un-aged parchments from goat kid and
calf skin and sorts of un-aged leathers from goat kid
and sheep skins vegetable tanned with quebracho or
mimosa, all manufactured at The Leather and Footwear
Institute (Bucharest, Romania). Pure gelatine from
Merck was used as received.
The parchment and leather samples were subjected
to accelerated ageing test performed in a climatic
chamber (Memmert HCP 108, Germany) at 85°C and
60% RH for progressively increasing time lengths (1,
2, 4, 8, 16 and 32 days). The samples were hung
in the chamber and precaution was taken that the
samples should not touch each other or the inner walls.
Also, on each opening of the chamber for extracting
the corresponding samples, the remaining ones were
repositioned in order to provide as uniform as possible
ageing conditions.
The TG/DTG/DSC+FTIR measurements were
performed on a Netzsch STA 409 PC thermal analyzer
coupled to a Bruker Tensor 27 FTIR spectrometer
equipped with a TG-IR gas cell, in nitrogen, synthetic
air and oxygen atmospheres at 10 K/min heating rate.
The denaturation and melting studies were
performed by recording of DSC curves in nitrogen
flow and deionised water, using DSC 204 F1 Phoenix
instrument produced by Netzsch, Germany.
The dynamic mechanical analysis (DMA) was
performed on samples in water, using a submersion
clamp mounted on DMA Q800 instrument (TA
Instruments, USA) at a heating rate of 1 K/min, or in
air at a heating rate of 3 K/min using a tensile clamp.
The treatment of samples consisted in soaking of
samples in acids, bases, inorganic salts of alkaline and
transitional metals, typically 1 M, for at least 24 h,
which was necessary for the penetration of solutions
within the collagen fibers and fibrils, followed by
washing with distilled water and filtration, and then
drying and rehydratation in air at room temperature.
The influence of pressure was monitored by applying
of a 10-tons pressure for 10 minutes on leathers
samples, both initial and extracted with acetone, by
means of a manual hydraulic press.
The TG/DTG/DSC/+FTIR analysis data of parchments
and leathers are similar to those obtained for pure
collagen in the previous stage of the project. While the
2D and 3D FTIR spectra of decomposition products
of parchments are almost identical to that of collagen
(due to the fact that parchments are composed up to
90% of collagen), some differences appear in FTIR
spectra of leathers. This is due to other non-collagenic

constituents of that are present in a larger proportion (up
to 30 %) in leathers, and which include tannins, lipids,
other proteins, etc. Thus, among bands corresponding
to decomposition products of collagen (noted in figure
1), a clear band appear at about 1350 cm-1 (encircled
with red in figure 1), starting with 2000C. This band
is characteristic for SO2 gas, which can evolve from
sulphated tannin extracts. Also, a supplementary
band is observed at 2060 cm-1 (encircled with blue in
figure 1) over 2500C and which is attributable to the
molecular specie COS. This volatile product is also of
non-collagenic origin and most probably derives from
keratin from hair residues [11]. On sampling from
different parts of leather, different intensities of these
2 bands are observed, suggesting the fact that the
vegetable-tanned leather is not uniform with regard
to the tannin composition, namely the tannins are
concentrated at the edges of the leather.

The influence of accelerated ageing is observed
in figure 2. Thus, for parchments it is clearly seen
that the incipient ageing already induces a large
decrease of shrinkage temperature (figure 4b), as also
observed in [10]. Particularly, the first day of ageing
has the maximum effect on hydrothermal stability. The
variations are very close indicating similar degradation
rates/ dynamics, most probably due to similar structure
of these materials. On further ageing the slope of lines
becomes less abrupt and the lines diverge from each
other suggesting different degradation rates.
For leathers a slightly different picture is observed.
Thus, the initial ageing induces a lower decrease of
shrinkage temperature as compared to parchments: for
example, after the first day of ageing the shrinkage
temperature is reduced by about 70C for parchments
and by ~40C for leathers. This is explained by the fact
that the ageing conditions used in this study (850C +
60% RH) are harsher for parchment than for leathers,
as the former denaturate at lower temperature. Also,
the lines diverge strongly for the four studied leathers,
indicating that these materials follow different
The salts of transitional metals did not affect the
denaturation (shrinkage) temperature in water of
parchments but had a major effect on leathers. Thus,
for example, in the case of a goat kid leather tanned
with quebracho extract an increase of denaturation
temperature of 13°C is observed on impregnating with
a copper (II) salt and with 24°C with a zinc (II) salt
(figure 3).

and zinc(II) salt(––).
The influence of solvents on the denaturation
temperature was monitored by immersion of samples
in mixed solutions of solvent-water for 24 h. The sotreated samples were let to dry and rehydrate in air at
room temperature. The aim of treatment of leathers

Storage Modulus (MPa)
with mixtures of solvents was the extraction of free
and weak-bonded tannins from the collagenic matrix
of these materials. The effect of this extraction was
monitored by DSC and DMA measurements in water.
Thus, if the treatment with a 1:1 acetone-water
mixture the denaturation endotherm of one new
leather shifts from 82°C to 77°C, then by using a
more polar solvent, dimethylformamide, (in a 1:1
mixture with water) leads to the decrease of DSC
peak to 68°C. Similar results were obtained also by
performing DMA measurements in water. It is known
that tannin molecules form hydrogen bonds with
the functional groups of collagen and contribute to
stabilization. By their removing following the extraction
with solvents the leather structure becomes similar to
that of pure collagen and thus the denaturation takes
place at a temperature which is characteristic for pure
collagen (65 – 700C). The decrease of denaturation
temperature is stronger with the solvation strength of
the solvent. However, even when extracting with DMF
a part of tannins remains bonded to leather, which can
be visually noticed (the leathers retain their brownish
colour). One can suppose that these tannin molecules
are bonded directly to collagen molecules, but form no
more significant interactions between them and suchtreated leathers denaturate at the same temperature
as pure collagen.
The use of solutions of bases and acids on
parchments has led to their gelatinisation or even
solubilisation. The leathers were also very sensitive to
basic medium but have shown a remarkable resistance
to acid treatment. Thus, for example, o new leather
treated with 1M ammonia solution suffered a decrease
of about 200C of the shrinkage temperature but
apparently no change in the position and enthalpy of
the denaturation endotherm following immersion in a
1M HCl solution for 3 days.
The influence of pressure was studied by applying
of a 10-tons pressure for 10 minutes on leathers
samples, both initial and extracted with acetone, by
means of a manual hydraulic press. The so-treated
samples were characterized by DMA in dry state. It
can be observed (figure 4) that the storage modulus
of new untreated leather shows a typical variation
as a function of temperature [12]. The application of
pressure leads to the increase in modulus value on all
temperature domain, as a consequence of the increase
in cohesion between the collagen fibrils. The treatment
of the same initial leather with acetone, followed by
the application of pressure leads to a stronger increase
of modulus and to a typical curve for pure collagen and
parchments. This is due to the removing of particles
of free tannins from within the collagen fibrils and to
stronger compaction of this structure when pressure
is applied, until a structure typical for collagen and
parchments is obtained.

CONCLUSIONS
The first TG/DTG/DSC/FTIR measurements of some
parchments and leathers were performed, both in inert
and oxidative atmosphere, which put in evidence the
molecular species that evolve on thermal decomposition.
The effects of temperature and humidity on the
denaturation behaviour of parchments and leathers
both in water and in dry state were investigated, by
performing accelerated ageing tests. The influence
of some factors such as acids, bases, inorganic salts
of alkaline and transitional metals, pressure etc., on
the denaturation behaviour of these collagen-based
materials in water or in dry state was studied.

Scientific and Technology Park „International Green Innovation
Park” – a new organizational model to incubation and support of
innovative companies
On October 9, 2013, took place the first meeting
of the founding members of Scientific and Technology
Park „International Green Innovation Park - IGIP”. The
meeting took place in Bucharest, under the patronage
of the General Association of the Engineers in Romania
(AGIR). The meeting was chaired by Their Excellencies,
Mr. President, Prof. Mihai Mihăiţă and Mr. Vice
President of the Academy of Technical Sciences of
Romania, Prof. Florin Teodor Tănăsescu.

Scientific and Technology Park IGIP is a RomanianChinese initiative to develop a framework for bilateral
cooperation as viable mechanism for development and
economic advancement, which can lead to progress
and social welfare in the short and medium term,
while providing a large number of jobs. IGIP Park was
established to promote the use of research results, the
application of advanced technologies in the economy
and to increase the participation of institutions of higher
education and research in the social and economic
development through science and technology.
This initiative was approved by the Order no.
4901MD of 27/08/2013, of the Minister Delegate for
Higher Education, Scientific Research and Technological
Development, at the request of the founding members:
National Institute for R&D in Electrical Engineering
ICPE-CA, City Hall Avrig and Chinese partner Beijing
Chengtong Reorient Investment Consultancy Co. Ltd.
The purpose of the meeting was to establish
future directions for specific action, while considering
the available of resources required infrastructure
construction and possible financial mechanisms to
be involved. IGIP will focus on development and
presentation of sustainable high-tech solutions, but
also aims to achieve a nationally exclusive mandate
for developing, testing and demonstrating the latest
technologies in the field. During the meeting it was
considered in the following areas:
- joint identification and development of projects
in the fields of: research and innovation, environmental
protection, wastewater treatment technologies, energy
efficient buildings, waste management, smart grids,
smart cities, clean transport, new energy technologies
and new materials;
- providing a platform for the Romanian and
Chinese companies, for project development, testing
and experiments.
Can say that the AGIR working meeting had a
special significance in the bilateral relations, with
significant economic influences; the Chinese founder
presented as intention an investment of 1 million Euros
in the first 2 years of Park development, while planning
attract of investment funds up to 50 million Euro in the
next five years, from various companies in China.
IGIP Park aims to implement a new organizational
model for incubating and supporting the development
of innovative companies. The traditional model requires
sustained support from the state and preferential
policies, so in the first stage to make large-scale
investments in the development of fixed assets and
their management. So, the Park development is based
on the investment in fixed assets.
The IGIP model has as priority the project development
in collaboration with incubated companies. The new
Park is not based on public investment and also does
not require in the first stage the major investments in
the development of fixed assets. Depending on the
characteristics and needs of projects, there are used
local and private resources. The goal is to develop
a model of opened Park in Romania, which can be
expanded nationwide. This experimental and innovative
model is adapted to the concrete need for economic
development in Romania.
The new model of Park, first of all, corresponds to
the situation in Romania and the needs of sustainable
development; secondly, based on the project, identify
local partners, stimulating economic development and
creating jobs in the different areas of the country.
Besides of support services in the fields of science
and technology, the IGIP park aims to provide
institutionalized services for state and private companies,
using a variety of financial instruments including direct
lending to projects, consultancy in investment, advice
on corporate restructuring, management services for
asset and stock exchange listing.
IGIP Park is administered by “IGIP Park Management
Company” Ltd. („Societatea de Administrare a Parcului
IGIP” SRL), established in Romania, Bucharest, District
3, 313 Splaiul Unirii, inside of INCDIE ICPE‑CA,

important
level of support among respondents for: thermal solar
(hot water), photovoltaic solar (electricity), geothermal
energy, wind energy, hydro energy, biomass energy,
tidal energy and waste incineration. There is a large
opposition regarding nuclear energy. The only options
that have no opposition are wind energy, thermal
solar energy (hot water), photovoltaic solar energy
(electricity), geothermal and cogeneration of electricity
and heat. Subjects reported a relatively high level of
‘No opinions’ on the tidal energy, cogeneration system
of electricity and thermal production combined with
heat and heating system. This may indicate that there
is little understanding of these systems and how they
work in practice.
3. Do you have sufficient information on renewable

Responses to this question show a large number of
respondents who do not have a system EE.
3. You are aware of the barriers that prevent the
installation of the above options on your property?
The responses show that the biggest obstacle is the
cost reported among respondents. Most respondents
considered that regulations on spatial planning are
an obstacle for the installation of renewable energy
sources.
4. The purchase a house / building for business
would be more likely to buy a home with facilities for
renewable energy?
To this question it shows that most respondents would
be more likely to buy a home with renewable energy
installations.
5. What type of fuel do you use for the following
domestic and how often?

RENERGY?
Responses to this question demonstrate that a
large number of respondents request information
and consultation, but there are a similar number
of respondents who would RENERGY information
on the project.
CONCLUSIONS
• Respondents had a high level of awareness of the
issues and recognition of its importance;
• Respondents had a high level of interest in RE and
EE;
• Respondents reported a relatively high level of EE to
take action, but recognize that energy efficiency levels
could be further improved;

1.3. Electronic waste in Romania
New strategy for waste management in Romania
proposes measures to ensure the transition from the
current model of development based on production and
consumption, to the model based on waste prevention
and use of materials recovery industry, thus ensuring
the preservation of national natural resources. In this
context, special attention should be paid to the waste
arising from electrical and electronic equipment. [1].
According to EU requirements, Romania has
committed that, since 2008, to collect annually 4 kg
per inhabitant of waste from electrical and electronic
equipment, which represents an amount of approx.
84,000 t annually (for a population of 21,698,000
inhabitants) but also costs of around 175€ per tonne
of waste recycled and processed (a considerable
amount for the Romanian economy).
1.3.1. Large household appliances
In this category are included: refrigerators and the
like, washing machines and dishwashers, cookers,
stoves and hotplates, heaters and other household
appliances
1.3.2. IT and telecommunications Equipment
In this category are included:
a. data processing equipment (CPU, minicomputers,
printers)
b. Personal computer (desktop, notebook, office
electronics, photocopiers etc.)
c. terminals and users systems (fax, telex, phones
and other products of transmitting sound, images and
information).
1.3.3. Consumer equipment
This group includes: television, radio, video, audio
and other equipment for recording or reproducing
sound and images, etc.

1.4. Electronic waste component. The impact of nonmetallic component
1.4.1 Electronic waste component
Electronic waste includes complex and special
components, which involves the compliance with
specific requirements (as is shown in the Figure 2
below):
.
Fig.3. WEEE classification
1.4.3. Impact of non-metallic component (Fig. 4)
Plastics represent the major component of nonmetallic electrical and electronic waste and are, in
terms of quantity, the second constituent existing in
WEEE (about 21%).
In electrical and electronic equipments, are used
very often plastics like: styrene (ABS, ASA, SAN, PS,
HIPS) and polypropylene (PP) which represent about
70% on total used plastics.
In these conditions, those polymers must be
considered like a priority within the efforts for plastic
recycling from WEEE.
Fig.2. Metallic component of CI
1.1.2. Electronic waste classification
Department of Trade and Industry (DCI) in the UK
have played a major role in the development and
implementation of the WEEE Directive. DCI’s web site
includes a non-statutory guidance document for WEEE.
The following decision tree is taken from the notes of
guidance and it is useful to determine if your product
is covered by WEEE (Figure 3 below):
Glass: represents 5.4% form the total weight of
WEEE, about 90% of glass 90% coming from cathode
ray tubes (TV’s and monitors).
Barriers to WEEE recycling glass from:
• variations in the composition of the glass;
• limited request.
Potential uses of glass:
• CRT Recycling;
• glass recycling; separation of lead from glass and reusing of glass;
• decorative, glazes for ceramics, glass bricks, glass
X-ray protection shields.

2. Technical requirements for recycling of nonmetallic component from WEEE
WEEE Directive is based on art. 175 of the Treaty.
The European Member States may adopt stricter
measures for environmental protection, as long as
these measures are in accordance with Community
legislation (such as the free movement of goods
laid down in art. 28-30 of the Treaty). Annex IA of
the WEEE Directive contains a list of categories of
products covered, and Annex IB a list of products in
these categories. Since this list is not exhaustive, if
they so decide, Member States may include also in
national legislation other products implementing the
WEEE Directive. Purpose of the Directive is primarily
to prevent WEEE, and in addition, to promote the
reuse, recycling and other forms of recovery in order
to reduce the disposal of waste. The Directive also
aims to improve the environmental performance of all
operators involved in the life cycle of electrical and
electronic equipment, e.g. producers, distributors and
consumers and in particular those operators directly
involved in the treatment of WEEE.
The RoHS Directive is based on Art. 95 of the
Treaty. The aim of this Directive is to harmonize the
legislation of the Member States in order to limit the
using of dangerous substances in EEE and to protect
the health and recovery / disposal of waste electrical
and electronic equipment.
3. Technological possibilities for separation of WEEE
non metallic component by two raw materials selected
feeds (corresponding of two kinds of high market value
raw materials)
3.1. Electronic waste non-metallic component
separation technologies
3.2. Improving the processing technologies
4. CONCLUSIONS
Preventive action is one of the principles underlying
the Emergency Ordinance no.195/2005 regarding
the environmental protection, Directive 2008/98/EC
on waste (transposed into national law by the Law
no.211/2011 regarding the waste hierarchy and showing
which “applies as order of priority legislation and policy
on waste prevention and waste management, such
as: prevention, preparation for re-use, recycling, other
recovery, e.g. energy recovery and disposal”).
In this respect, new strategy on waste management
in Romania proposes the measures to ensure the
transition from the current model of development
based on production and consumption to the model
based on waste prevention and use of raw materials
issued from recovery industry. According to Annex of
HG 448/2005, electrical and electronic equipment are
classified in 10 categories. Of these, in the present
study, were selected for analysis three categories
considered as representative (in terms of importance
and share in number and weight): large households,
telecommunications equipment and consumer goods.
4.1. The results of the analysis regarding population
endowment with electrical and electronic equipment
(which provides implicit information on results of EEE
waste) indicated the following:
- Evolution of the electrical and electronic equipment
endowment of Romania population had varying trends
in the last decade, with periods of growth until 2010
and drops due to economic crisis.
- Regardless of the analyzed period, the endowment
continues to be well below the average of other
European countries or the U.S., due both to the fact
that EEE’s are used much more than the average
duration of use declared by the manufacturer and the
inability to achieve a collection rate close to 100% of
waste from EEE in households. Under these conditions,
the potential collection of WEEE is less than 3.75 kg
/ capita and year (amount calculated for a maximum
potential of approx. 30 Kg EEE per capita according to
national statistics).
4.2. Electronic waste contain a rate of approx. 50
% ferrous metals , iron and steel (with high potential
for recovery and recycling) and approx. 13 % ferrous
metals (Cu, Al, Pb) and precious metals (Ag, Au, Pt,
Pd). An important component is also represented by
printed circuits which are the most complex parts of
EEE. Although only handle approx. 3% of the total
weight of WEEE, this component creates problems
regarding waste management and possibilities of
recycling.
4.3. Plastics represent the major non-metallic
component of electronic waste and is, in terms of
quantity, the second constituent existing in WEEE
(about 21%). The next place in the non-metallic
component is represented by glass (about 5.4 of
the total weight of WEEE). These components raise
questions about recycling due to mixtures of different
materials, contamination and low price (if plastic)
or due to compositional variations (if glass) and low
demand in the market.
4.4. EEE which can be recycled is contained in
specific legislation. Thus, according to HG 448/2005,
the categories of electrical and electronic equipment
that can be recycled are: large and small household,
IT and telecommunications equipment, lighting
equipment, consumer equipment, electrical and
electronic tools (with except large-scale stationary
industrial tools), toys, leisure and sports equipment,
medical devices (with the exception of all implanted
and infected products), monitoring and control
instruments, automatic dispensers.
National projects
4.5. Non-metallic components of WEEE can be
recycled under the WEEE Directive, RoHS Directive
and International Treaties (allowing harmonization
of legislation of Member States to limit the use of
hazardous substances in EEE and contributing to the
health and recovery and disposal of electrical and
electronic waste).
4.6. Collection of WEEE should take into account
their origin (from private households - individuals
or from other sources than private households businesses). For each source, there are specific
methods of collection which include among others:
selective collection by the local government, the
return of WEEE by final holders directly to authorized
entity for collecting and treating these types of waste,
dismantling equipment by employees of the point of
collection right on the spot; return of WEEE by the
economic final owner directly at the point of collection,
replacement by distributor of WEEE with new products
at the premises of the economic agent and the return
of arising WEEE at the point of collection.
4.7. There are various specific methods for
recycling non-metallic component from EEE, methods
applied in specialized units for these operations. In the
paper are presented in detail two such technologies,
namely: “technology to recover metals and plastics
from waste of IT and telecommunications equipment”
and “materials recovery technology from the
monitors”. These technologies involve steps such as:
decontamination, dismantling, sorting, separation and
processing, followed by the election of machinery for
recovery of components.
The costs of this activity (collection and treatment
of waste from electrical and electronic equipment)
usually consist of: collection costs (transport+ handling
costs); treatment costs; costs of sorting, dismantling
costs, disposal costs through storage, communication
costs etc.

EXPERIMEMNTS
1. Density
1.1. Density of powder
The measurement was realized according to SR ISO
3923-1 and SR ISO 3923-2 standards. In the Figure 1
below, is presented the procedure for determining the
powder density, while in Figure 2 are presented the
results.
Fig. 2. Comparative values of the density for the
analyzed samples
1.2. Density after pressing
In this case, the density was measured after pressing
at room temperature, at 3.5 tf, only for the Sample
no.1.
The pressed sample has the following dimensions:
d=1.2cm, r=0.6 cm, h=2.2x10-1cm and the weight is
0.51g. The calculated volume is V=πr2h=0.2486cm3,
so the calculated density is ρ=2.05 g/cm3. The
obtained value indicates an increase in density with
1.39 units after pressing, compared with powder
density (0.66 g/ cm3).
2. Thermal analysis
2.1. Thermal conductivity
The measurement was performed only for Sample
no.1, after pressing. The obtained results at room temperature indicate
the value of thermal diffusivity α= 0.178 [mm2/s],
thermal conductivity λ=0,355 [W/mK] and specific
heat Cp=0.376 J/g/C.
2.2. Thermogravimetric and dynamic diferential
calorimetric analysis (TG-DSC)
Analysis were been realized on TG-DSC Analyzer
type STA 449 F3 Jupiter, NETZSCH, Germany,
according to ASTM E831-2006.
In the Figures 3, 4 and 5 below are presented the
TG-DSC curves for all samples:

374.3°C with mass loss of 2.49%. Over 600oC, the
powder mixture is pre sintered, undergoing very slight
compaction.
In the case of Sample 2:
TG curve (continuous green line) indicates five mass
loss of: 10.88% (25–400oC), 9.91% (400-480oC),
7.80% (480-720oC), 6.89% (720-790oC) and 2.47%
(790-900oC). The total mass loss is 37.89% across
the entered studied temperature interval (25-900oC).
In association with the variation of DTG curve (dashed
green line), on DSC curve (continuous blue line)
can be observed more endothermic decomposition
phenomena of the polymeric material revealed at
certain temperatures, depending on the considered
heterogeneous material. The most striking processes
of decomposition of oxides, were recorded at 358.3°,
454.9° and 774.5° for which values were higher
enthalpies: 37.23 /g, 86.93J/g and 103.9J/g.
Were recorded also more endothermic decomposition
phenomena of the oxides across the entered studied
temperature interval (25-900oC), on TG curve been
identified the related mass loss. Can be observe
equally, two decomposition processes of the polymeric
material at maximum temperatures of 457.7°C and
760oC respectively, with values of enthalpies of 40.41
J/g and 11.04 J/g.

TG curve (continuous green line) indicates three
mass loss of: 11.07% (25–350oC), 2.49% (350460oC) and 5.09% (460-800oC). The total mass loss
is 18.55% across the entired studied temperature
interval (25-800oC).
On DSC curve (continuous blue line) can be
observed a small phase transformation (at 84.8oC),
followed by a polymer melting endotherm process
(at 182.1oC), a strong reactive oxidation in two steps
(exothermic process), possibly arising due to the
existence of oxygen in the material, with a maximum

INTRODUCTION
The most recent directions in supercapacitors field
focus on developing supercapacitors based on CNT and
their composites. Thus, possibilities of supercapacitors
stability and capacity growth by using CNT composites
type CNT/oxides CNT/polymer are studied worldwide.
Structural, electrical and mechanical characteristics
of carbon nanotubes [1-3] determined the enhanced
interest for using them as electrode materials
[4-7]. Development of new composite materials
by incorporating CNT in active phases with
pseudocapacitive properties (oxides, polymers) led to
new generations of supercapacitors [8-11]. Supercapacitors
based
on
polymer/CNT
composites
Conductive polymers exhibit the following
advantages as supercapacitos materials:
- high specific capacitance because the loading
process involves the entire mass;
- high conductivity in loaded state.
The main disadvantage of using polymers in
supercapacitors is the cycling stability due to
contraction and appearance of crevices and cracks
during further cycles. This disadvantage can be
prevented by introducing CNT inside polymer, such
composite electrode materials having the advantage
that the mesoporous network achieved by attaching
the CNT into the polymer can adapt to volume
changes [12]. This forbids the appearance of crevices leading to increased stability of cycling capacity. In this
context, the purpose of this paper consists in obtaining
conductive polymeric coatings of 3D CNT structures
obtained by CVD for achieving conductive electrodes
used
in
mini-supercapacitors,
micromechanical
characterization of the achieved electrodes in terms of
morphology, architecture and covering conditions and
their electrochemical activity test. Project research team

EXPERIMENTS
The achievement of hybrid polymer-carbon
structures was aimed by carrying out electroactive
polymeric coatings of 3D CNT/CNF carbonic structures
electrochemically, by electropolymerization, using
CNT networks obtained by CVD method previously
presented. As an alternative to 3D carbonic structures
obtained by CVD growth, experiments for achieving
conductive polymeric coatings were carried out from
monomers solutions containing carbon nanotubes.
3D CNT networks were obtained by CVD growth on
silicon substate (100) type n, with catalyst layer based
on iron or nickel, carried out by e-beam method. During
the experimental process of CNT growth by CVD
method, C2H4 was used as carbon gaseous source. The conductive polymeric coatings achievement
experiments were carried out by using a Voltalab 40
potentiostat/galvanostat. The technique used was
cyclic voltammetry. Pyrrol electropolymerization was
carried out by potentiostat cycling (50 succesive
cycles) between 0.2- 0.85V/SCE, at a scanning speed
of 20mV/s.

All experiments were carried out in stationary
conditions. Pyrrol solutions were prepared before the
beginning of each electrochemical polymerization
and kept in darkness to avoid its air oxidation and
polymerization. To encourage pyrrol dissolution, 3-5
ml of ethanol were added. As a results of the carried
out experiments the samples presented in table 1 were
obtained.
Polypyrrole polymeric coatings were characterized
morpho-structurally by scanning electron microscopy,
using FESEM/FIB/EDS Auriga equipments produced by
Carl Zeiss Germany, with minimal resolution of 1 nm at
15 kV and 1,9 nm at 1 kV, the acceleration voltage of
1-5 kV, the used detector being SESI type (Combined
Secondary Electron Secondary Ion).

Scanning Interferometry) and PSI (Phase Shift
Interferometry). The measurement conditions were:
temperature 24 °C, humidity 76% and the measuring
errors introduced by microscope calibration were of
0,01% for VSI mode and -0,1% for PSI mode. Before
carrying out the determinations, calibration was
achieved.

Thickness determination of the conductive layer was
carried out by measuring the difference level between
deposition surface and substrate surface in resulted
channel after scratch resistance determination. Various
profilograms were made by appropriate selection of
heights matrix lines of the surface and the thickness
of the total deposited layer was measured by individual
heights mediation in the deposition area and in the
channel. For a better estimation of deposited layer
height, a histogram of the measured heights was
made and peaks correspondent to height points of the
deposed layer and of the channel, respectively, were
selected.
Electrochemical activity test of electrodes obtained
by CNT networks covering with conductive polymers
was carried out by using a VoltaLab 40 potentiostat/
galvanostat equipment.

Electrodes test was carried out by the following
methods:
• Open circuit potential (I = 0A);
• Cyclic voltammetry (E = 200 ÷ 850 mV/SCE
with a potential scanning rate of 20mV/s);
• Electrochemical impedance spectroscopy (f =
100kHz ÷ 10mHz, at 10mV amplitude);
• Time variation capacity at constant frequency.

A standard cell with 3 electrodes was used, a platinum
auxiliary electrode, a calomel saturated electrode SCE
and a working electrode, respectively, which was the
tested sample. The electrolytes in which measurements
were carried out were 0,2M H2SO4 and 0,2M oxalic
acid.

be observed the appearance of a duplex (2 Debye
semicircles, well outlined), corresponding to the answer
given by the appearance of two distinct interfaces.
By circular regression the electrochemical parameters
corrsponding to each Debye semicircle were carried
out and are presented in Table 2. Fig. 5. presents the
capacity variation curves dependent on potential, at
stable frequencies, for sample 6 (PPy+CNT)/D in
0,2M H2SO4 (at constant frequency of 48Hz) and
0,2M oxalic acid (at constant frequency of 100Hz)
solutions. It can be observed that in the case of 0,2M
oxalic acid solution, capacity values are with 1 order
of magnitude lower than in the case of 0,2M H2SO4
solution. Maximum capacity values are registered at
550mV/SCE in the case of 0,2M H2SO4 solution and
850mV/SCE, respectively, in the case of 0,2M oxalic
acid solution.
CONCLUSIONS
The following achievements were carried out:
A. Development of polymeric coatings for 3D CNT/
CNF structures;
B. Micro-mechanically characterization (scratch
resistance, roughness and thickness of the polymeric
layer);
C. Test of electrochemical activity related with
different electrolytes by voltammetry, potentiometry
and (EIS) electrochemical impedance spectroscopy.
3D CNT networks were obtained by CVD growth on
silicon sublayer (100) type n, with catalyst layer based
on iron or nickel, carried out by e-beam method.
Experiments for achieving conductive polymer
coatings with polypyrrole for 3D CNT networks grown
by CVD method were carried out. As an alternative,
the achievement of hybrid polymer/CNT networks was
attempted by pyrrol electropolymerization with CNT
from the electrolyte solution. From the experimental
data, for polypyrrole deposition by cyclic voltammetry,
the optimal conditions determined were:
-
potential range 0,2 – 0,85 V/ESC;
- scanning speed 20 mV/s;
- solution: 0,1M pyrrol in 0,2M H2SO4 and 0,3M
pyrrol in 0,2M oxalic acid;
- minimal number of cycles 50.
In order to investigate the quality of the obtained
deposition, were characterized from morpho-structural
point of view by SEM. From the morphological analysis
of electrodes achieved resulted as optimal structure,
CNT individual covering, respectively, resulted in the
case of PPy/CNT_A sample. From the electrochemical
characterization (EIS, voltammetry, potentiometry)
resulted:
- the specific capacity maximum value (F/cm2) is
achieved in the case of PPy/CNT_B hybrid electrolyte
when tested in 0.2 M oxalic acid (C=17.55 * 10-3 F/
cm2);
- the minimal dielectric loss at 50 Hz is achieved in
the case of PPy/CNT_C hybrid electrolyte when tested
in 0.2 M oxalic acid (tg δ=0.14).

Research and development of new functionalities for sports and health garments
ABSTRACT
Developing e-textile architecture to serve as
a software/hardware architecture for a class of
applications will require the establishment of a set
of precepts. The precepts will help the user make
decisions governing the application being created.
These precepts will be based on past experience and
developing concepts
Future research and advances in the area of electronic
textiles will enable a plethora of applications ranging
from accomplishing the simplest of everyday chores
to mapping a fi re fighter’s location in a smoke filled
building. Embedded system technologies alongside
smart materials can be integrated and interfaced to
create new possibilities. Advanced e-textile systems
will require simultaneous hardware and software
design operations.
In this project INCDIE ICPE‑CA proposed and develop
an experimental model of a human perspiration sensor
along with a device applied for biologic motilities
monitoring (experimental trials).
INTRODUCTION
Intelligent textile is considered as interactive when
incorporated wearable technology (a cardiac monitor
or an MP3 Player) or the fabric itself is reactive at
external stimuli. Based on the reported research
findings remarkable advances are registered mainly
in the field of surface modified fibres (able to react
at temperature changes, moisture level or any other
external factor).
An interactive textile must accomplish following
requirements:
a. to collect and send information;
b. protection: to protect the wearer by accidental
interferences with embedded electronically devices;
c. resistance – mechanical stress resistant -enough
to sustain the integrity of electronic component;
d. comfort - ensuring the monitoring features.
From literature survey are depicted two types of
sensorial monitoring:
1. Chemical monitoring: is referring to those
materials, sensors and devices able to react/ detect
changes in body fluids: (ex: perspiration monitoring –
detecting compositional changes)
2. Physical monitoring: detection of those parameters
such as: temperature, various biological motilities
(muscle motilities, tissues, limbs - motilities, changes
in body temperature etc).
Wearable textile-based sensors that can provide
real-time information regarding sweat activity: A pH
sensitive dye incorporated into a fabric fluidic system
is used to determine sweat pH. To detect the onset
of sweat activity a sweat rate sensor could also be
incorporated into a textile substrate. The sensors are
integrated into a waistband and controlled by a central
unit with wireless connectivity. The use of such sensors
for sweat analysis may provide valuable physiological
information for applications in sports performance and
also in healthcare
Conductive elastomers are a novel strain sensing
technology which can be unobtrusively embedded into
a garment’s fabric, allowing a new type of sensitized
cloths for motion analysis. A possible application for
this technology is the remote monitoring and control
of motor rehabilitation exercises.
The first trials have been based on piezoelectric
elements adapted to an textile substrate. Thus,
several piezoelectric plates have been placed into an
flexible string which has been placed directly on a
human subject. First in the thorax area and next in the
abdominal area. Has been recorded a variable voltage
time dependent and proportional with variation of
pressure developed on piezolectric elements surface
(the pressure exerted on piezoelectric elements).
Experiments lead to quantitative evaluation of
monitored physiological parameters, sizing of sensors
and checking the admisibility barrier.
In regard with potential of developing a human
perspiration sensor has been approached 3 experimental
paths:
1. design/developing
sensors
based
on
conductive yarns;
2. design/developing sensors by chemical
modification of a textile substrate;
3. design/developing sensors grid type with cosensitive deposition layers.
All the resulted sensors have been tested by
measuring those answer in tension or/and capacity as
a result of trace sensing of perspiration solution (when
come into contact with artificial solution).

EXPERIMENTAL
The three dimensional structures present interesting
possibilities in applications requiring conductive
characteristics. Such applications are extremely vast
and diverse, including domains such as protective
clothing, buildings/architecture, medicine, security
systems/army, etc. The conductive polymers present
interesting possibilities for the development of
intelligent textiles, especially e-textiles.
Adding the required circuitry, power sources,
electronic devices, and sensors to standard fabric
garments makes the simplest of these so called “smart
clothing” items. More sophisticated prototypes for
smart clothing items use conductive threads to weave
switches, circuits, and sensors into the fabric itself.
These can be achieved through multifunctional fabrics,
commonly referred to as electronic textiles (e-textiles)
or smart textiles, capable of making daily life healthier,
safer, and more comfortable.
In this project the sensors experimental variants
has been evaluated from point of view of compatibility
with textile (fabric).
By compatibility with the fabric (textile) mean:
washing resilience (n washing cycles).
Textile sensor made by chemical modification
of fabric with conductive polymer, proved to be the
most efficient variant in terms of response time (2-5s)
and accuracy and selectivity (sensor characteristics
are dependent by the type of fabric- hydrophilic
characteristics). This type of experimental sensor has
been subjected to a number of washing cycles as in
the next scheme:
Experimental condition:
• Test samples: fabrics of (40mmx20mm);
• Temperature: room temperature 200C; 400C;
600C;
• Washing time: 10 min; 30 min; 45 min; 60 min;
1:30min; 2 h;
• Fabric types: V1; Glat; PES;
• Washing water:
• Tap water;
• Water with 1% detergent.
Fabric samples have been chemical modified by
vapour impregnation with conductive polymer. Test
fabrics have been subjected to repeated washings as
was stated before.
For the „Final prototype - technical documentation
for prototype product / developing fabric components
– stage of the project, INCDIE ICPE-CA both with
MAGNUM SX SRL has been realized:
1. models of socks made form multifunctional yarns
and testing trails in real conditions (technical reportevaluation, annex 1-Magnum SX). Internal evaluation
committee of MAGNUM SX selected a final prototype
code V2 for:
1. pulse monitorizing - conductive yarns were knitted
in the area of superior cuff;
2. for perspiration monitoring: conductive yarns
were knitted in the lower area of the cuff.
The results in this respect were no satisfactory
according to the project objective. The industrial
partner proposed that technical solution of a fabric
with conductive yarns to be applied for developing
orthosis/medical bandages and monitoring in this way
the pulse.
2. rassiere designed for perspiration monitoring
In this case the option was in favour of the
experimental sensor obtained by chemical modification
of a fabric (textile substrate).
The experimental model has been subjected to the
final evaluation from the view point of compatibility
with the textile substrate.
Based on the results obtained during the trails
could be stated that this variant is feasible from the
economical point of view (the sensor could be used
also in disposable variant). Thus, this research could
be continued on textile sensor- chemical modified
weave-developing variant for:
1. design and developing the complete sensorial
system: sensor-transducer next to the wireless system
for data (information) capture;
2. thoroughness study of selectivity perspiration sensor.
CONCLUZIONS
In this stage, has been realized:
1. socks experimental models from multifunctional
yarns which were tested for gradual compression and
pulse/perspiration monitoring (V2 variant) (fig. 1).
Fig. 1. Technical report
For pulse monitoring - conductive yarn are knitted in
the superior cuff area;
For perspiration monitoring: the yarns are knitted in
the lower area of the cuff.
Results regarding perspiration sensor: time of
reaction: excellent (1-5s depended by the type of
fabric); high selectivity in regard with urea, ammonia
and lactic acid concentration (accuracy of response).
2 Brassiere designed for perspiration monitoring
MAGNUM SX SRL re-designed the brassiere model
resulting two new variants considered as prototypes:
- variant 1 (fig. 2);
- variant 2 (fig. 3).

When brassiere was re-designed were created special
patch pockets where has been fixed a rigid/solid sensor
developed by INCDIE ICPE-CA, as it follows:
variant 1: inserting sensor for perspiration
monitoring

monitoring (sensors grid type with co-sensitive
deposition layers)

In order to highlight innovation support services and
identify new services in this class, the Italian partner
of the consortium has achieved a questionnaire. ICPECA sent this questionnaire to organizations from the
country involved in funding and supporting innovation
and also to start-ups. The survey results will provide the
basis of a training material to develop the competence
of organizations involved in the early-stage funding of
innovative ideas.
ICPE-CA also developed, based on a methodology
and structure developed by the Hungarian partner,
a National Study on the financing of innovation.
In the first part, the study comprises of a series of
macroeconomic data on research and innovation
funding: the share of GDP spent on R & D in 20072011, investment in research and development of
economic agents, evolution and structure of R&D
personnel. It is also do a review national system of R&D
and intellectual property legislation. It also presented
business environment: its dynamics, patterns of
innovative companies. The chapter on financing
innovation in this field includes government policies
and private funding categories available in Romania to
finance innovative businesses in the early stages. The
last chapter describes organizations policies aimed at
developing entrepreneurial culture in order to increase
access to private equity funds (business angels, equity

ABSTRACT
The project aims to improve the accessibility in
Calarasi-Silistra cross-border area by promoting joint
clean and energy-efficient road and river transport
systems and to improve cross-border policy coordination
among local public administrations. By these means
better transport services for the citizens from crossborder area will be created, and accessibility and
mobility of people and goods will be improved. Due to
the implementation of innovative technologies within
the joint transport system the project objectives will be
achieved with minimum effects on the environment.
INTRODUCTION
In order to design the joint clean and energy-efficient
road and river transport system several technical and
economical studies regarding the renewable sources
potential (solar, wind, hydro, biomass) in the crossborder area, the existing methods for design and
manufacture of river boats powered by renewable
energy sources, the electric vehicles and energy storage
stations etc. have been accomplished. Also, the Danube
flow speeds have been evaluated and two series of wind
measurements have been performed in Calarasi city
area.
The project proposes to develop common planning
documents for designing clean transport services in
the Romanian-Bulgarian cross-border area, to elaborate
a guide for clean and energy-efficient road and river
transport systems and to develop two ecological boats
powered by renewable energy sources, for Danube
crossing between Calarasi and Silistra and also for
tourism in protected areas. Research staff of the project

Bilateral Programme Romania – Russia Investigation of the NiAl, Ni3Al and NiTi materials structure using neutron diffraction techniques
ABSTRACT
Bilateral cooperation between ICPE-CA, Romania
and JINR, Dubna, Russia has as main objective the
investigation of alloyed intermetallic compounds using
neutron diffraction techniques. The Romanian part was
involved in the manufacture of the materials and the
Russian part was in material investigating using the
neutron diffraction technique. During this phase were
made and characterized Ni30Ti50Cu20 type materials,
using four fabrication technologies.
INTRODUCTION
In order to obtain inexpensive products, researchers
have applied nearly every known synthesis method
in efforts to enhance the production methods and to
obtain materials with improved properties. The powder metallurgy techniques offer the
potential of near-net-shape processing without or with
low microstructural segregation and the possibility to
exploit the evolved energy during reactive synthesis of
the NiTi intermetallic compound [1, 2]. Reactive synthesis offers the advantage of both time
and energy saving in comparison with conventional
melting and classical powder metallurgy approaches.

EXPERIMENTAL
In this phase were made and characterized
Ni30Ti50Cu20 type materials using four manufacturing
technologies type:
1 - Mixtures of 200 grams were weighed according
to the chemical composition followed by hand
homogenization of the mixture by successive passes on
a sieve with a mesh size of 300 micrometres, followed
by pressing into a cylindrical die having a diameter of
12 mm at 4 tf/cm2 pressure and sintering at 870°C
for 2 hours in an argon atmosphere of 99.9% purity.
Cooling of the samples was performed in furnace and
in argon atmosphere.
2 - According to the same protocol to obtain powder
mixture set to 1, cylindrical samples with a diameter
of 40 mm were obtained by plasma sintering at 870°C
using Spark Plasma Sintering equipment.
3 – The mixture dosed according to paragraph 1
from protocol 1, was placed in a planetary mill and
mechanically alloyed for 20 hours at a balls / powder
3/1 ratio of load, and a rotation speed of 250 rot/ min,
in an wet grinding environment of petroleum ether and
possibilities for change the rotation direction of the
mill bowls The mixture thus obtained was subjected to
synthesis operations according to the protocol no. 1.
4 – The mechanically alloyed mixture according
to protocol 3 was subjected to synthesis operations
according to protocol 2. We have analyzed the
changes in the phase of the Ti50Ni30Cu20 shape memory
alloy type, using X-ray diffraction carried out at room
temperature. The temperatures of the martensite
transformation were studied by differential scanning
calorimetry. The martensite transformation evidenced
by thermal scanning was discussed in correlation with
the relative content of phases in the material.
Table 1 shows the density values obtained after
material synthesis according with the four protocols
used, at which density value for material synthesized
using powder mixtures mechanically alloyed for 10
hours under the same conditions was added. Tab. 1. The density values of the synthesized

Note that plasma processing technique by SPS, leads
to a densification greater than 95% of the synthesized
materials. In the case of mechanical alloying fabrication
protocol, it was observed that mechanical alloying
leads to lower density materials in the case of samples
processed by SPS and a slight increased of density
when materials were classical processed.

in the material - calculated by Rietveld method,

All materials are of multiphase type containing a
majority orthorhombic martensite phase B19 type and
two secondary phases, one responsible for the shape
memory effect, monoclinic martensite phase B19’ and

At room temperature, the shape memory materials
are of martensite type, at least two types of martensite
being present in the materials. The proportion of
phases is different depending on the synthesis protocol
followed. A large amount of phase which is responsible
for shape memory effect was obtained in materials
processed by SPS, the mechanical alloying greater
than 10 hours leading to the increase in the proportion
of the phase who is not responsible with the shape
memory effect.

The shape memory effect was present in the all
synthesized materials. The highest thermal effect was
obtained for the material obtained from mechanically
alloyed powder mixtures for 10 hours processed
according to Protocol 3. Table 4 shows the range of
martensite transformation (Af-Mf) and the thermal
hysteresis of the transformation (Af-Ms).
Although the martensite transformation is rather
broad (>30°C), like in the cubic to monoclinic
transformation (B2 - B19’), the thermal hysteresis
is greater than 12°C, except material synthesized
according to the protocol two. Narrow thermal
hysteresis is characteristic of NiTi alloys alloyed by Ni
substitution with Cu.
CONCLUSIONS
- The mechanical milling technique is a promising
alternative procedure to obtain SMA alloys with
improved properties. - Mechanical milling technique assures an improved
homogeneity of the mixtures and an appropriate
distribution of the elements in the obtained
mechanocomposite powders which is a guarantee for
better material synthesis. Therefore, materials with
good shape memory properties can be obtained.
- The SPS process lead to a better densification of
the synthesized materials.
- In the case of manufacturing process with
mechanical alloying, it was observed that the mechanical
alloying lead to the decreasing of the materials density
when these materials are processed by SPS technique,
and a slight increase of density in the case of materials
processed by classical route.
- The all synthesized materials are of multiphase
type, consisting of a majority orthorhombic martensite
type, and 2 secondary phases, one of them responsible
also with shape memory effect- monoclinic B19’
martensite phase, and another one which is a hardening
cubic phase, NiTi2 which is not responsible with the
shape memory effect.
- At room temperature the materials are of martensite
type, at least 2 martensite variants being present in the
materials.
- Largest amount of phase which is not responsible
with the shape memory effect was obtained in the
materials processed by SPS, mechanical alloying
leading to the increasing of the proportion of phase
which is not responsible with shape memory effect
greater than 10 hours leading to the increase in the
proportion of stage who is responsible for the shape
memory effect.
- The highest value of thermal effect was recorded
in the mechanically alloyed materials for 10 hours
processed according to the third protocol.
- The Ni-Ti-Cu synthesized alloys, show a narrow
thermal hysteresis that recommend them for MEMS
applications.

Research for the design of a plant for investigating the magnetic
properties of matter in the range of 3-300K by using a neutron
flux in the presence of intense magnetic fields
ABSTRACT
Within the research project was approached
the conception and the design of an experimental
model of intense (4T) and uniform magnetic field
superconducting generator. The generator is designed
in a Helmholtz system embodiment with HTS
superconducting coils made of YBCO tape type.
Cryogenic cooling is achieved by Gifford-McMahon,
two-stage crycoolers. The project provides also a
horizontal channel passing through the coil system, at
temperature of 300K, for access of the neutron flux in
the area of intense field. The project goal is to develop
a spectrometer for neutrons from the reactor IBR-2
(JINR-Dubna).
INTRODUCTION
So far, other types of spectrometers for fast neutrons
have been made with conventional electromagnets
(copper), which attained fields of maximum of 2T and
at the expense of large sizes (3-4 times larger) and
the need to be cooled with pressurized water. Another
type of electro-magnets, which allows obtaining
intense magnetic fields (4T) can be with LTS type
superconductors such as NbTi or Nb3Sn, but requires
very low temperatures (4.2 K) [1,2]. Another major
obstacle is the presence of liquid He in the system,
which is not recommended for use in the neutron flux
due to possible induced and unwanted nuclear reactions.
Thus, a suitable solution in the current circumstances
is the use of superconducting electromagnets of HTS
type (High Temperature Superconductors), which can
be made with YBCO type superconducting tapes, socalled thin-layer conductors.
The purpose of this research project is to design a
plant for generating intense and uniform magnetic field
(4T), for the making of a spectrometer for the analysis
of the materials exposed to the neutron flux in the
presence of intense electromagnetic fields. The project
objectives consist in the elaboration of a conceptual
model of the plant and the realization of an execution
project.
Thus, there was elaborated the conceptual model of
the plant, which contains:
- HTS superconducting coils cryostat, with complex
geometry (provided with warm channel for the access
of the neutrons and the access of the sample in the
high magnetic field area);
- Sample cryostat subjected to determinations (in
neutron flux), with its temperature control in the range
of 3-300K;
- The crycoolers (two) necessary for the HTS coils and
sample cooling with the characteristics: two cooling
stages, of 35W@50K and respectively 1,5W@4,2K;
- Superconducting coils system (two HTS coils – in
Helmholtz assembly);
- DC power supply at 0 - 500A of the superconducting
coils;
- Electronic protection system for superconducting
coils;
- Conductors (superconductors - HTS) of power supply
of the superconducting coils.

INTRODUCTION
The NiTi alloys with equivalent atomic composition
present a high technological interest, due to the potential
applications in various domains like biomedicine, naval
industry, aerospace, nuclear, automotive, robotics etc.
Shape memory alloys are used in coupling and
sealing apparatus because they combine big recoverable
deformations with considerable resistance. NiTi based
systems are the most successful shape memory alloys
because they have the best combination between
mechanical and functional properties and, in addition
to this, a good resistance to corrosion. The most important shape memory phenomena
are:
1. pseudo elasticity (PSE);
2. simple shape memory effect (SME);
3. double shape memory effect (DSME);
4. vibration dumping effect.
In addition to these effects, that have found practical
applications and are directly or indirectly related to
the martensitic transformation, there are some premartensitic effects that include R phase transformation
[1-10].
NiTi shape memory materials:
For the achievement of the objectives proposed
for 2013, it has been carried out the following
experimentations:
There was obtained and characterized two samples
of NiTi shape memory material by: mixing powders,
mechanical milling, pressing and sintering by spark
plasma at different temperatures and compositions
(Table 1), both processes taking place in vacuum
(controlled) atmosphere.

- Samples 2 NiTi: 51.5%Ni48.5%Ti.
All samples were pressed at 50 MPa and sintered by
Spark Plasma Sintering (Table 1).
♦ Samples 1 NiTi (mechanical alloyed) – after the
diffraction analyze it was noticed that all five NiTi
samples obtained for different alloying times present
the Ni4Ti3 precipitate and the NiTi stable phase
corresponding to the Bcc_B2 ordered structure after
the sintering treatment. Another aspect revealed by
the diffraction diffractograms was the identification of
the Ni3Ti and NiTi2 phases. The best result obtained
after the diffraction spectra analysis is the sample 1-5
NiTi, for T = 10500C.

The samples show some variations of NiTi
microhardness values according to the chemical
composition of the material, the degree of homogeneity
of the powder mixture and the distribution and quantity
of the added element, the compaction pressure, the
sintering temperature and the heat treatment.
Values for the Young’s modulus are located around
78GPa, which correspond to a Young’s modulus typical
to the austenite phase. We can also notice that the
Vickers hardness of NiTi materials obtained by powder
metallurgy and SPS has values within the normal limits
for this type of materials.
Some scientific results of the researches conducted
within this project were presented at the conference
“The 11th Conference on Colloid and Surface Chemistry
CCST, 2013, 9-11 May, Iasi, Romania” by the paper

CONCLUSIONS
In the present stage were used two technologies
for obtaining Ni-Ti shape memory materials: powder
metallurgy techniques and plasma sintering of powder
mixtures.
Mechanical milling was used only for obtaining
50.8%Ni49.2%Ti materials with good shape memory
properties. These powder mixtures were previously
alloyed mechanically at 6 hours and 8 hours in order
to avoid segregation of material and increase chemical
and microstructural homogeneity.
The samples were obtained by SPS for different
temperatures and compositions, the best results being
obtained for sample 1-5 mechanical alloyed for 8 h, at a
temperature of 10500C and for sample 2-2 synthesized
at 9000C.
The overall analysis of the data presented in this
study allows drawing some general conclusions on
the possibility of inducing superelasticity / pseudo
elasticity in NiTi alloys produced by powder metallurgy
and spark plasma sintering.

Study of transparent conductive films of zinc oxide doped with aluminium
INTRODUCTION
The increasing importance and potential opportunities
for TCO materials, increased the scientific work
carried out in recent years. The research resulted in
the synthesis of new materials but also increase the
volume of knowledge and evaluation of behaviour of
these new materials. Research carried out on the TCO
material has led to the understanding of the behaviour
thereof in a proportion of 90%. Therefore studies
are needed to lead to a full understanding of the
relationships between technology of targets, the film
deposition processes and properties of obtained thin
films. Transparent conductive oxides, based ZnO, have
emerged from the research which aimed to replace
indium oxide doped with tin (ITO) in optoelectronic
devices because of its high cost [1-3]. Research of
ZnO materials have attracted attention because of
low cost, chemical stability, and because it is nontoxic. Also, it has been taken into consideration the
optical and electrical properties of these oxide
semiconductors. Even if these materials are studied
for some time, there are still significant challenges to
overcome its properties, including: the development of
new deposition techniques allowing deposition at low
temperature (~ 25oC), processing of large area flexible
substrates, and control the morphology of these
films [1]. Therefore research is necessary to improve
the technology of targets, determine the optimum
parameters for the submission and processing of thin
texture of AZO.

During this stage, it was studied the process
of obtaining AZO targets, not sintered ceramic
ZnO:Al2O3 (98:2%) using a method that is less used,
Spark Plasma Sintering SPS - FCT System GmbH at
500oC and 600oC. For this purpose there was used
powders with high purity: ZnO (purity 99.9%) and
Al2O3 (purity 99.9%). ZnO and Al2O3 powders were
thermally treated at 600oC for 2 hours for removal of
any impurities. After the heat treatment the powders
are used in a mixing process which comprises several
stages: sieving through sieves with 200μm mesh
(used for granulometric separation and to mix the two
powders); 4 hours mixing at 60 rpm, the milling with
the planetary mill ball, with polyamide grinding chamber
and agate hard ball and homogenization through a new
sieving using 200μm sieve. Following this process was
obtained homogeneous powder (≤ 200μm).
Powder and target was characterized with X-ray
diffract meter Bruker - AXS D8 ADVANCE type and
scanning electron microscopy Crossbeam Workstation
(SEM-FIB) - Zeiss Auriga.
After the homogenization step, the powder was
subjected to X-ray diffraction using Bruker - type AXS
D8 Advance equipment. The measurement parameters:
X-ray copper anode tube, 40kV/40mA, kβ Ni filter, 0.04o
step, 2s point measurement, measuring range 20-80o.
In the fig. 1 shows the AZO powder diffraction, all
peaks correspond to ZnO as 01-071-6424 belonging
database International Centre for Diffraction Data. The
peaks corresponding to the aluminium does not occur,
this can be explained by the limited its incorporation
in the structure of ZnO, which is consistent with the
literature.

Utilization of the spark sintering plasma method
for obtaining targets, it is necessary a carbon mould,
having a diameter of 50.08 mm and a height of 3mm.
The samples were heated to 500°C and that at 600°C,
applying a pressure of 125 MPa and maintaining these
parameters for 3 minutes and 30 seconds. After
pressing the mould together with the target were
cooled.
Further targets were characterized with X-ray
diffractometer Bruker - AXS D8 ADVANCE type.
The measurement parameters: X-ray copper anode
tube, 40kV/40mA, kβ Ni filter, 0.04o step, 2s point
measurement, measuring range 20-80o. In the fig. 2
shows the results obtained from this analysis. As can
be seen, all peaks belonging to ZnO which confirm that
a target was treated at a temperature lower than the
sintering. From the obtained diffraction patterns can
also be seen that the intensity of the peaks increase
with increasing temperature, so that the target treated
at 600°C have the highest degree of crystallinity.

Scanning electron microscopy analysis was performed

and the images obtained were performed to a
magnification of 100,000x, fig. 3. SEM images of the
target compressed at 500°C (fig. 3 a) shows that its
microstructure is characterized by a high porosity and
an inhomogeneity.
Also, there may be notice irregular polygonal particles.
When pressed at 600oC target can be observed also
irregular polygonal particles. Grains can be observed
which are composed of many particles, they retain their
polygonal shape. However pressed at 600°C AZO target
microstructure is characterized by an inhomogeneity and a high porosity (more than 500°C when pressed
target), these characteristics are in accordance with
the principles of recrystallization and growth theories
particles present in the first stage sintering.
CONCLUSIONS
Were obtained ZnO:Al2O3 targets pressed with spark
plasma sintering method at different temperatures
(500oC and 600oC). Following the study conducted
was revealed the following:
-
Oxide powders used must to be well homogenized
in a process which includes several steps (by sieving,
mixing in mill ball and then again sieving);
-
Pressing must be carried out at a pressure
minimum 120 MPa;
-
In order to obtain not sintered target, should be
carried out at a maximum temperature of 500°C, at
a highest temperature appear properties of the first
sintering step.
Considering the above, it is established that
experimental studies performed to obtain not sintered
AZO targets using spark plasma sintering method,
supplemented by a comprehensive characterization
(structural and morphological) are able to provide
important information.

Conductive multifunctional nanocomposites PMMA / graphite,
graphite oxide, graphene investigated by SANS method
ABSTRACT
The purpose of the research project in collaboration
with the JIRN Dubna, Russian is to investigate the
structure of graphene-polymer composites and their
derivatives by neutron scattering techniques at small
angles - SANS.
The general objective of the project is to design
and produce a series of multifunctional conductive
nanocomposite PMMA / nanographite, graphite
oxide, graphene used in electromagnetic interference,
consisting of three stages that take place over 3
years.
INTRODUCTION
Graphite, graphene and materials derived from them
has a huge scientific interest in recent years due to
the exceptional electrical properties, mechanical, high
specific surface and so on [1-4]. The applications of
the carbon composite materials was in reinventing
by the utilization of nano size derivates of graphite
us graphene, reduced graphene oxide, graphite oxide
and graphene oxide. An important role are played in
the polymeric composites because of the nanosise
derivates of graphite have the ability to change
drastically the mechanical, electrical and optical
properties of composites even at low amount [6-9].
The price of nanosize derivates of graphite present a
low cost comparative with nanotubes, unfortunately in
the both case the industrial processing is expansive.
The nanomaterials with structure related to the
graphite as nanographite, expanded nanographite,
graphene single and multilayer, and graphene with
oxygenate functional groups (graphite oxide and
graphene oxide) exhibit unique electrical, magnetic,
mechanical properties.
The project proposes is to design and produce a
series of multifunctional conductive composite PMMA
/graphite, nanographite, graphite oxide, graphene used
in electromagnetic interference application, classified
according to the nature and size of the additive that is
used on three classes of polymeric nanocomposites:
composite with graphite us etalon, composite with
graphite oxide, and composite with graphene.

EXPERIMENTAL
Multifunctional graphite/ PMMA composites with
graphite mass amount raging between 1-70% were
synthesized by hot pressing method. The samples
with graphite filler / PMMA matrix, were characterized
in terms of electromagnetic properties (electrical
conductivity versus frequency electric field strength
versus frequency transmitter and efficiency versus
frequency electromagnetic wave attenuation versus
frequency) at high frequencies between 0.6 -3 THz.
In order to fulfil the mechanical properties required
of a structural material for electromagnetic shielding,
mechanical testing was performed.
In order to determine the mechanical properties
mechanical test were performed using microhardness
type XMO 195 FM 700 series, CSM nanoindenter
with Berkovich diamond type 93, rod 0,2micron. From
nanoindentation tests using nanoindentation force
10 mN were calculated by Oliver & Pharr method the
Vickers hardness, Young’s modulus and stiffness.
The electromagnetic behaviour of the graphite /
PMMA composites in the electromagnetic field with
the frequency range from 0.6 to 3 THz is strongly
influenced by the content of carbon (Fig. 1) as
follows:
– Samples with high amount of carbon (20-70 %)
present high electromagnetic attenuation (> 175 dB),
–Samples with low content of carbon (1%) present
moderate electromagnetic attenuation (> 75 dB).
The results recommend these materials to be used
as structural materials for filters and electromagnetic
shielding in function of the filler concentration versus
frequency.

Figure 1. Graphical representation of shielding
efficient at THz frequency
Mechanical properties of graphite/ PMMA composites
were influenced by filler content, the synthesizing
method and working parameters (temperature and
pressure). of the studied composites present Vickers
hardness with values comprised of 20-40 HV, while the
Vickers hardness of the polymer matrix present values
comprise of 50-53 HV, the hardness decreasing with
working temperature. The indentation hardness ranges
from 0.5 to 0.3 GPa, being inversely proportional to
the amount of filler. The rigidity is approximately equal
for all composites, ranging between 0.02 to 0.03 mN
/ mm, without no visible correlation. The Young’s
modulus is very closely for all composites, with
values range between 3.9 to 4 GPa, decreasing with
increasing graphite content. Depth of penetration (for
a 10 mN indentation force) is directly proportional to
the amount of filler introduced, showing values ranging
between 1000 and 1500 nm. Mechanical properties of
the investigated composites are comparable to those
of a multi layer wooden board.

curves under constant loading –unloading as a
function of time for graphite / PMMA composites

graphite/ PMMA composites (33% graphite)
CONCLUSIONS
From the point of view of electromagnetic attenuation
the composites PMMA with high content of carbon
(20-70%) present high electromagnetic attenuation (>
175 dB), and those with low content of carbon (1%)
present moderate electromagnetic attenuation (> 75
dB). Relating to the concentration versus frequency,
they can be used as structural materials for filters and
electromagnetic shields.
The Vickers hardness, respectively Young’s modulus
of the graphite / PMMA composites range between
20-40 HV, respectively from 3.9 to 4 GPa, being
inversely proportional to the amount of filler. Depth
of penetration (for 10 mN indentation force used) is
directly proportional to the amount of filler introduced,
showing values between 1000 and 1500 nm.
Mechanical properties of graphite /PMMA composites
were influenced by filler content, the method of
obtaining and working parameters (temperature and
pressure), being comparable to that of a multi layer
wooden board.

Investigation of crystalline and magnetic properties in micro- and
nanostructured systems based granular alloys
INTRODUCTION
The granular magnetic materials have become
very attractive for groups of researchers around the
world, especially in the current context of search for
new magnetic materials for the permanent magnets,
without rare earths, based on cheaper and nondeficitary raw materials. In these composites, magnetic
fine particles, of the order of a few nanometers, are
embedded by specific processing techniques, in a
metallic or insulating matrix. Due their microstructure
and of the possibility to configurate the properties and
the geometrical parameters, these materials possess
different properties, and sometimes more performing
when compared with their bulk counterparts. The
research efforts focus on identifying new Fe-based
alloys, with soft or hard magnetic properties. Another
area of study, as important as that mentioned above,
dealt with the giant magnetoresistance (GMR)
observed in granular nanostructures, many studies
being devoted to the investigation of GMR dependence
on materials microstructure [1 - 5]. The Fe-Cu and CoCu binary systems seem to be promising candidates
for the synthesis of granular alloys, with special
magnetic properties. The project aims (i) to prepare
glass-coated microwires and ribbons based micro- and
nanostructured alloys from the Cu-Co, Cu-Co-Ni, Fe-Cu
systems and (ii) to study their physical and structural
properties.

microwires has been investigated by scanning electron
microscopy, at 50000x magnitude. It was emphasized
the presence of alotriomorph echiaxes grains, of the
oversaturated solution (see figure 5).

The magnetic granular systems are generated by
a subsequent annealing of the oversaturated solution
at high temperatures. In order to create granular
structures, with the desired magnetic properties, in the
second stage of the project will be done annealing of
the studied alloys, leading to the segregation of two
phases, with fcc crystalline structure.
CONCLUSIONS
It has been prepared trough Taylor‑Ulitovski method
metallic glass-coated microwires, from Cu-Co and CuCo-Ni alloys. The investigations by scanning electronic
microscopy carried out a microstructure characterised
by the presence of alotriomorph echiaxes grains,
specific for the oversaturated solution. The subsequent
annealing will lead to the segregation of two phases,
with crystalline structure fcc type, being generated
in this way the granular structure in the synthesized
materials.

Prospective studies for assessing the opportunity to develop a bioreactor for energy generation based on organic waste and wastewaters
ABSTRACT
This project aims to develop contacts between two
research teams of ICPE CA, Romania and BIOMA,
China, for the implementation of biogas technologies
and recovery of the residual biomass local potential.
There has been achieved an assessment of the biomass
potential in the towns Avrig, Romania and Guangyuan,
China, by collecting and analyzing specific data locally.
Romanian specialists have visited Sichuan region of
China in scope of experience exchange for research
activities on biogas production. Visiting the Institute
BIOMA and selecting optimal location to build a
bioreactor in Guangyuan city, China, have also met an
important goal of this project first stage.
INTRODUCTION
The project has as a main scope to complete and
continue of some on-going researches carried out under
national research programs by creating connections
and communication tools at international level with
other research institutes having similar research goals.
China is well known for its national program to promote
and use of biogas.
In China, there have been installed more than 35
million household biogas plants up to now, ensuring
an annual production of ca. 12 million m3 biogas. The
goal proposed by the Chinese government for the year
2020 in developing of biogas sector is to have achieved
ca. 80 million biogas plants [1].
Cooperation between the Romanian partner ICPE-CA
and the Chinese partner BIOMA is important and
beneficial to both parties. The Romanian partner has
ongoing a national project Nucleu entitled “Increasing
the efficiency of equipments and technological
processes for the conversion of energy from renewable
resources”, in which research on the optimization of
the anaerobic bioreactors is conducted. The need to
exchange experiences in the application of the research
results, with real benefits for both sides, is an important
goal of this project.

In the first project stage 2013 information regarding
the responsible entities for implementing the project
has been collected.
There have been presented the current status
and future concerns concerning the developing of
renewable energy based projects in the communities
of Avrig, Sibiu, Romania and Guangyuan, Sichuan
Region, China. Furthermore, there have been shown
the economic sectors like agriculture and zootechnics
which generates organic waste to be recovered to feed
a bioreactor. The arable land and pastures areas have
been assessed and specific crops have been mentioned
in this stage report.
Moreover, the registered local farms, data on
population dynamics and labour force, information
about climate and relief, the current situation of water
supply, the sewerage system, the potential for organic
sludge generated in waste water treatment plants
as well as aspects related to domestic and industrial
waste management have been reported [2].
The concerns of local officials to implement clean
energy technologies in Avrig and Guangyuan have
been highlighted. There have also been presented local
programs for renewable energy sector [1], [3].
Likewise, the opportunity and need for developing
of some more local programs based on renewable
sources by implementing a bioreactor for biogas
production from organic waste and wastewater has
been presented [4], [5].
The data collected on-site have shown that it is
appropriate to implement a bioreactor to generate
energy from alternative sources in the related towns
Avrig and Guangyuan.
The bioreactor proposed to be developed based
on the current prospective studies is a hybrid system
that combines different techniques and methods for
generating energy (biomass, photovoltaic, pneumatic,
wind) starting from anaerobic digestion of biomass
such as biodegradable waste (food waste, catering
residuals, municipal organic waste, agro-zootechnical
waste, etc.), but also energy crops. [6].
The two municipalities have set out in their local
development plan designing and implementation of
a high capacity bioreactor, in scope of solving the
problem of waste and sludge generated in sewage
treatment plants while providing biogas, electricity and
heat, as well as ecological fertilizers. [1], [5].
Within this project stage, work visits of Romanian
specialists in China have been done where the partner
institute BIOMA and its ongoing projects on biogas
technology have been presented. The guests visited
the laboratories of the institute and attended some
experimental research activities for biomass recovery
to biogas.
There have been visited several biogas plants
developed and implemented by BIOMA Institute in
Sichuan Province in the following cities: Guangyuan
district Yuanba - biogas plant from Weifeng Agriculture
Co. Ltd, Yongwang District Wangcang - biogas reactor
Wangcang County, Sichuan Province, Yixing district
Xichong - biogas plant of Nonsheng Company, Xichong
County and biogas in progress to Nonsheng Company,
Xichong County.
In the figures below there are shown some
representative images from the activities of experience
exchange at BIOMA Institute, China, as well as during
work visits made in Sichuan region.

CONCLUSIONS
By achieving the activities of this project stage
entitled “Prospective studies on the local potential of
organic waste and wastewater; Analysis of current
status on treatment and recovery of waste and
wastewater. Work visits”, the project goals to establish
contacts between two research teams having common
objectives in implementation of new technologies for
the production of energy from renewable sources, in
recovery of the local potential of residual biomass and
reduce dependence on fossil fuels, have been met in
its entirety.
Assessing the potential of organic waste and
wastewater in the towns Avrig, Romania and
Guangyuan, China, which have envisaged in their local
development plan to implement a bioreactor for the
production of energy, has been proved an essential
step to justify the necessity and feasibility of the
investment.
Through the implementation of this project, there
will be possible to provide the community biogas,
electricity, heat, materials extracted from algae as well
as organic fertilizers. In addition, by the implementation
of this bioreactor, a solution for waste and waste water
recovery will be provided. This solution will bring direct
benefits to the local agricultural development, will
lead to the creation of new jobs in rural areas and will
reduce the phenomenon of inhabitants’ migration from
rural to urban areas [6].

Advanced techniques and interdisciplinary studies for improved
assessment of historical parchment documents
ABSTRACT
The differential scanning calorimetry (DSC) was
used for assessment of the deterioration degree of
parchments extracted from Italian and Romanian
documents. In this purpose, for each sample of
parchment, the DSC analyses in water excess and in
nitrogen flow were performed for putting in evidence
the degradation on amorphous and crystalline zones.
The obtained results will ground the conservation
treatments and the restoration procedures of the
investigated documents.

characterization of parchments from patrimonial objects
that is based on the thermal analysis techniques.
b. Investigation of the degradation of some Romanian

Materials
It was investigated samples of parchments extracted
from the Italian and Romanian documents supplied
by:
- National Military Museum King Ferdinand I,
Bucharest;
- National Museum of Moldavia, Iasi;
- City Museum of Bucharest;
- V. A. Urechia Library, Galati;
- Archivio Storico dell’Università degli Studi di Torino;
- Archivio Storico della Città di Torino.
It was also analyzed some sorts of recent parchments
manufactured by INCDTP‑ICPI Bucharest.
Methods
The used method was the differential scanning
calorimetry (DSC) with the apparatus DSC 204 F1
Phoenix – produced by NETZSCH GERATEBAU GMBH
– Germany. The analyses were performed in the
following two conditions: DSC analysis of the samples
immersed in water and DSC analyses of the direct
extracted samples, in high purity nitrogen flow.
Figure 1 shows the DSC curve obtained for a
sample of parchment manufactured from goat skin,
immersed in water for 24 h; similar DSC curves were
also obtained for all investigated parchments [1, 2].
The extrapolated onset temperature of denaturation
in water is equal with the shrinkage temperature (Ts) and
is a measure of the degradation degree of the analyzed
material. For a recent manufactured parchment, this
temperature is about 600C (±1.50C), while for de
degraded parchment this is lower than 560C. The
degradation degree increases with the decrease of
shrinkage temperature.
Figure 2 shows the DSC curve obtained in nitrogen
flow for an old parchment sample; similar DSC curves
were also obtained for all investigated parchments. At
the progressive heating of sample of parchment, in the
temperature range of 250C...2550C, two successive
endothermic processes occur, namely dehydration and
the melting of the crystalline zone of material. The
crystalline zone of material stability is characterized by
the value of melting temperature, which corresponds
to the minimum of the second endothermic peak.

The results analysis shows that close values of Ts
were determined by DSC and MHT methods. The low
differences are due to the material heterogeneity and
to differences between the heating rates at which the
determinations were performed (10 K.min-1 for DSC
and 2 K.min-1 for MHT).
Figures 4-6 show the dependencies of the shrinkage
temperature on the duration of accelerated ageing,
for different parchments and conditions of ageing.
For humid ageing at 800C and 80%RH, the values of
Ts increase when the ageing duration increase (see
Fig. 4). For UV irradiation, the shape of the curve Ts
vs. t is complex. It results that at UV irradiation, the
parchments exhibit a complex process of deterioration,
which could consist by breaking of cross-linking
bonds, followed by partial remake of these bonds. In
order to clear up this complex mechanism, the results
obtained by DSC analyses must be correlated with
those obtained by other physical-chemical methods.

Advanced research for obtaining carbo-graphite heat resistant
materials, exposed to irradiation, with high life time, for seal rings
ABSTRACT
The main goal of the project consists in obtaining of
some carbo-graphite heat resistant materials, exposed
to irradiation, with high life time for seal rings.
The importance of the materials used for nuclear
plant’s equipments is done both by the special
functional conditions and required reliability.
The seal rings obtained during the project, are
designed for use in nuclear power plants where are
required specific operational conditions (temperature
and radiation)

EXPERIMENTAL
1. Have been identified and documented methods
for evaluating the behaviour of carbo-graphitic material
at temperature and radiation respectively, developing
a rapid method for estimating the material behaviour
under irradiation combined with heat stress.
2. Were been performed, using the technological
facilities located solely in equipping of SC ROSEAL
SA Odorheiu Secuiesc, three experimental models of
resistant Carbon materials subjected to irradiation with
long lifetime , for seal rings: MCTIF – experimental
model of carbo-graphitic material with phenolic
impregnation material based on resin RESITAL B type;
MCTIP - experimental model of carbo-graphitic material
with polyester impregnation material and MCIT Ez
665 - experimental model of carbo-graphitic material
with impregnation material based on ecological LISA
1 type.
For each of the three experimental models have
been established both technological parameters on
each stage of the workflow execution and control
parameters intermediate/ final functional tests required
to verify the quality of their products and ensure
reproducibility of the manufacturing process. Complete
tests have been performed on the technological flow.
3. The three experimental models have undergone a
full program of tests and analysis in accordance with
the assessment methods identified, namely:
- Determination of thermal behaviour of solid
materials and products by means of simultaneous
thermal analysis (STA) thermo gravimetric analysis and
differential scanning calorimetry (DSC + TG );
- Determination of material thermo-oxidation stability
using the chemo-luminescence method;
- Quick Estimation of temperature and radiation
behaviour by determining the changes in mechanical
properties (compression strength, flexural strength and
hardness Rockwell) under heat stress combined with
irradiation.
The tests were conducted on the technological
equipment and devices fitted to SC ROSEAL SA,
while tests, analyzes and measurements to assess
experimental models (in accordance with the methods
for evaluating behaviour of carbo-graphitic material
under temperature and radiation) were conducted
exclusively on equipment fitted to ICPE – CA.
Based on the results obtained in the previous phases
of the project “CARBOTIR” on technology and
facilities available to SC ROSEAL, was established
the technology to obtain some carbo-graphite heat
resistant materials, exposed to irradiation, with high
life time for seal rings. This technology has been used
to obtain the experimental models with the three
different impregnation materials and therefore the
processing conditions.
Regarding the ultimate control of experimental models,
based on the investigations, have been established as
crucial to the project specific application the following
measurements:
•
Determination of density;
•
Analysis of macroscopic appearance achieved by
optical microscopy technique;
•
Determination
of
mechanical
properties
(compression strength, flexural strength and
Rockwell hardness);
•
Leakage - functional test.
During the characterization program, have highlighted
the following:
Thermal behaviour [1]:
• All experimental subjected to analysis does not
show significant degradation at 2000C (high maximum
temperature expected to be reached by accident is
150°C). Moreover, were observed some periods with
improved behaviour after exposure to temperature in
combination with irradiation;
• MCTIF - up to 2000C, the total mass loss (indicator
of thermal degradation) stood at 1.76 %, reaching a
maximum of 2.13% after exposure to temperature
combined with irradiation. The maximum degradation
speed is reached at about 5360C;
• MCTIP - up to 2000C, the total mass loss stood
at 3.34 %, with decrease to 1.18 % after exposure to
temperature combined with irradiation. The maximum
degradation speed is reached at about 5770C;
• MCIT - up to 2000C, the total mass loss stood
at 0.83 %, which is also found after exposure to
temperature combined with irradiation. The maximum
degradation speed is reached at about 5720C.
Thermo-oxidation stability using the chemoluminescence method [2]:
• In all cases, the actual temperature of the start of
the degradation process (oxidation) is greater than the
expected operating temperature of the sealing rings
(150oC);
Fig. 1. CL curve for MCTIF model
Fig. 2. CL curve for MCTIP model
Fig. 3. CL curve for MCTIE model
MCTIP respectively MCITE - onset temperature of
degradation (oxidation) is 180°C, very close to the
maximum temperature expected to be reached during
operation inadvertently sealing rings (150oC);
• Under normal conditions, all materials have the
same willingness to oxidize, which does not distinguish
them, especially to a temperature of 150°C;
• After exposure for 10 days at 1800C, the materials
are however different oxidation rates: the lowest speed
(slowest oxidation) is associated to model MCTIP;
• Prolonged exposure to maximum temperature
and irradiation to the maximum dose expected to be
absorbed by accident during operation (10MRad) does
not affect the stability of the materials, which are
designated to be suitable for the specific application
project. Under these test conditions, however, the
stable model is MCIT.
Fast Estimation of temperature and radiation behavior
by determining the change in mechanical properties of
heat stress combined with irradiation [3]:
• mechanical characteristics do not suffer major
changes in heat stress and / or irradiation for all three
experimental models tested. Thus:
• for MCTIF -by applying radiation in combination
with heat stress, there is a variation in the compression
strength of approx. 10%, in bending strength of approx.
8%, while the practical values of Rockwell hardness
falls in the machine error (0.2%);
• for MCTIP- by applying thermal stress in combination
with radiation there is a variation in the compression
strength of approx. 11%, in bending strength of approx.
6%, while Rockwell hardness values practically do not
change.
• for MCIT - by applying thermal stress in combination
with radiation there is a variation in the compression
strength of approx. 18%, but with improved values after
exposure for 10 days at 1800C (due to the completion
of the curing process of impregnating material), in
bending strength of approx. 4%, while the practical
values of Rockwell hardness does not change.
CONCLUSIONS
- It was drafted the assessment methods manual for
carbo-graphitic material behaviour at high temperature
and radiation;
-There were performed three experimental models
of carbo-graphite heat resistant material, exposed to
irradiation, with high life time for seal rings;
-The three experimental models were been
characterized according to the methods for evaluating
of the carbo-graphitic material behaviour at temperature
and radiation.
Setpoints required values for the corresponding
mechanical characteristics specific application project
- seal-rings are:
- compression strength: min. 100 MPa;
- bending strength: min. 50 MPa, both normal and
heat stress conditions combined with irradiation;
- relative to the corresponding mechanical
characteristics required for the specific application
project - ring seal material - the MCITE model does not
fall within the requirements;
- MCTIF model presents the appropriate values for the
test under normal conditions (102.14MPa compression
strength value and 53.73MPa bending strength value)
and decreases slightly below the required values under
combined heat stress and radiation (91.58MPa for
compression strength value), but remains within limits
for the bending strength (50.03MPa);
- MCTIP model presents the best values of mechanical
resistance even under heat stress combined with
irradiation (average values for compression strength of
117MPa and flexural strength of 54MPa).
In all cases, mean Rockwell hardness was within
the limits of 123-128 units.
- The methods for evaluating the behaviour of
carbo-graphitic material under temperature and
radiation conditions, shows that experimental models
type MCTIF and MCTIP fall in the range of technical
features values required for specific application of the
“CARBOTIR” project, with an addition to maintaining
the mechanical characteristics for MCTIP type model.
- For all tests were been used the supplied equipment
and analytical techniques established in accordance
with project objectives.

dezvoltarea comunei Radovanu
rigole către drumul judeţean (DJ)
Radovanu-Şoldanu, ca toată apa să
se ducă pe DJ, lăsând în urmă pământ, pe un drum pietruit, dovedind astfel, că există o iresponsabilitate, atât ca cetăţean cât şi în
calitate de consilier local. Nu poţi
deversa toată apa pe un drum judeţean, dacă îţi pasă de comunitatea în care trăieşti, mai ales că e un
drum folosit de toată lumea şi întreţinut de primărie. În ultimii ani,
am profilat şi compactat acest
drum, prin sponsorii şi relaţiile
profesionale pe care le am, ca primar, cu firmele care au lucrat în
Radovanu, fără să dăm bani de la
buget pentru lucrare. Sigur nu se
teme nici de oprobriul public, nici
de amenzi, pentru faptele sale,
pentru că, inclusiv, amenda dată de
ITM, în valoare de 1 miliard de lei
vechi, pentru munca la negru, a
fost radiată de instanţă. Nu se teme
de amenzi şi nici nu îşi doreşte să
intre în legalitate.”, spune primarul
comunei.
Renovarea bisericii, în
atenţia Primăriei
„Chiar dacă întâmpinăm greutăţi la proiectele care trebuie votate
cu 2/3-imi, deoarece pentru 1 singur vot, nu trec proiecte importante, reuşim să promovăm investiţii,
care au nevoie de votul a jumătate
plus unu, dintre consilieri.
Astfel, prin hotărâre de Consiliu
Local, s-au alocat 60.000 de lei
pentru renovarea exterioară a bisericii Sf Gheorghe. Lucrările sunt în
curs de execuţie, s-a efectuat o parte din lucrare şi, în cel mult, 30 de
zile vrem să terminăm investiţiile.
Este mult de lucru la această biserică şi sper, ca anul viitor, să pot să
obţin fonduri pentru pictura din interiorul bisericii”, afirmă primarul.
Ca nemulţumire...
Structura Consiliului Local mă
nemulţumeşte cel mai tare, deoarece acţiunile consilierilor USL nu au
la baza lucruri obiective, motive
reale. Nu poţi spune că ai motiv real
să refuzi venirea unui medic stomatolog la Radovanu, sau că au fost
motive reale când au refuzat, în
mandatul anterior, ca Radovanu să
primească subvenţie de la APIA de
1,4 mld de lei vechi; că există motive reale să nu vrei apă şi canalizare
la tine în comună ori să concesionezi serviciul public de salubrizare,
când Garda de Mediu te amendează
pentru lipsa acestuia? Sunt motive
înguste, subiective, care ţin chiar şi
de frustrări personale, aşa cum se
întâmplă în cazul consilierului Partidului Conservator, Iulian David,
care a candidat de 2 ori la funcţia de
primar şi nu a câştigat niciodată!
o echipă de pompieri cu trei motopompe, care a lucrat, neîntrerupt, 48
de ore. A fost evacuată apa din mai
multe gospodării: Stefanache Nicolae, Chirnogeanu Gheorghe, Bogatu
Marin, Guresoae Maria. Datorită situaţiei care s-a creat, în urma precipitaţiilor abundente, am hotărât să renunţ la banii alocaţi întreţinerii drumurilor din interiorul comunei şi voi
propune Consiliului Local aprobarea
transferului acestor bani de la drumuri, la lucrări de decolmatare şi săpare a unor canale, care să preia tot
excesul de apă din comună şi să-l de-
verseze în râul Argeş. Aceste canale
nu au fost decolmatate de peste 25 de
ani. Nu este un lucru uşor, dar este
absolut necesar, declară primarul comunei Radovanu.
Ce v-a bucurat și ce v-a
nemulţumit, în acest prim
an, după alegerile din
iunie 2012?
După ce am câştigat al doilea
mandat, mi-am propus să punem
în aplicare alimentarea cu apă şi
canalizare şi suntem în faza de a
desemna câştigătorul care va lucra
cei 21 de km, pe fondurile Ministerului Dezvoltării Regionale.
Marele merit, în obţinerea finanţării pentru acest proiect, îi revine
domnului senator PNL, Iulian Dumitrescu care ne-a ajutat foarte mult
în această problemă şi nu numai.
Sunt extrem de mulţumită de colaborarea cu dl senator Dumitrescu şi
am convingerea că, împreună, vom
continua modernizarea comunei
Radovanu. Profit de ocazie, să îi
mulţumesc şi pe această cale!
Ce le transmiteţi
locuitorilor?
„În mesajul meu de la alegerile
de anul trecut, am spus: Nu votaţi
pe cartofi şi ceapă, votaţi un om
care a dovedit că poate şi care a
realizat, în comună Radovanu,
timp de 4 ani, mai multe proiecte
decât şi-a propus. Oamenii au înţeles, dovadă că sunt, în continuare, primarul lor. Le transmit să aibă
încredere aşa cum au avut şi până
acum!”, spune primarul comunei
Radovanu, Vasilica Dobrescu.
Ploile torenţiale căzute, de
curând, au inundat multe
gospodării
Fenomenele naturale au creat
probleme, în urmă cu două săptămâni, în localitate. Cantitatea de precipitaţii, care a căzut între 30 iunie şi
1 iulie, a fost de 186 de litri pe metrul pătrat, în 24 de ore, o cantitate
mult prea mare pentru a putea fi absorbită de sol, şi, astfel, mai multe
gospodării, din comuna Radovanu,
au fost inundate. Acţiunea pornită a
fost una contra-cronometru.
„Am cerut ajutorul pompierilor
de la Olteniţa, zona de care aparţinem, dar aceştia nu au putut interveni, în prima parte a intervalului,
pentru că au avut o situaţie extremă,
în municipiul Olteniţa. Înainte de
venirea pompierilor, duminică noaptea, cu trei motopompe, una a primăriei şi două ale consilierului local,
Marius Dan Alecu, căruia îi mulţumesc, pe aceast cale, am acţionat în
zonele grav afectate.
După două zile, cu sprijinul inspectorului-şef al ISU Călăraşi, Daniel Popa, căruia în mulţumesc foarte
mult pe această cale, ne-a fost trimisă

EXCELLENCE CENTRE
FOR INITIATION OF YOUNG
OLYMPICS TO SCIENTIFIC
RESEARCH
I have no extraordinary talent for something. I’m just extremely curious.
The most beautiful and profound human experience is my mysterios.
(Nu am nici un talent anume. Sunt doar extraordinar de curios.
Cea mai frumoasă și profundă trăire omenească este misterul.)
Albert Einstein
Excellence Centre for Initiation of Young Olympics to Scientific Research
If it were to identify a story of ideas to initiate
scientific research center for young Olympians, then
this is the success story of Stefan (Iov) and Alexandru
(Glonţaru), with whom I lived one of the strangest and
fabulous adventures in 2013, adventure which I think
is perhaps the most important of my life...
In the fall of 2012 I was asked by a good friend
Professor Ioan Ardelean of the Institute of Biology of
the Romanian Academy to assist in a research project
on spiders, a team of students (Stefan and Alex), both
of them Olympic, one in chemistry and the other in
physics.
We have organized the first meeting in October
2012, and then until 2013 at INESPO Olympics, the
Netherlands, we held a training seminar of the project,
every Thursday at 9, with a consistency which is
not very mature researchers found. The result was
the obtaining of Silver Medal at the competition of
INESPO in June 2012 and then winning the Olympics
on research projects in Romania, which has led in
qualification to INTELL 2014 from USA.
Last but not least, to remember in this story, the
essential role of company STAR STORAGE that made
possible the participation in the Olympics in the
Netherlands, with the feeling that the Ministry of
National Education had no idea of this event and the
performance ...
For me and for many researchers, research should be
seen as a game (see Fr. Bacon, Newton, Fermi, Ortega Y
Gasset, Robert Feynman ...) and not as entertainment;
I recognize, the mentality less appreciated by the
Romania in a constant state of transition, in which
we learn today that education and research should be
conducted more by the political administrators (see the
opinion and decision of the politicians today, when the
tradition, in all countries, is that the people of science
have a very good reputation, and not the people who
have no idea of it).
Many times I hear it beating his fist on the table, “…
we don’t play, we made products …” (as the scientific
research purposes would have no material purpose in
the end).
Yes, I have found the two young Olympics a fresh
joy of the game and a generous power for swimming in
rough waters of knowledge, actually the first important
key to science. Schiller said “… the most serious are
the children when they play …”, and so you wonder
why new enlightened adults have the right to be bored
in dealing with the children and become “a sister’s
boss” too fast (see Flight Over the Cuckoo’s Nest, the
American film and also the play staged at the National
Theatre of Bucharest).
Therefore, the consequence of this success story,
which showed that it is possible, of course, that children
who projects are deserving and especially competitive
(yes, and that I appreciated that Stefan and Alex
look forward and joyfully accepted the competition,
attention, a specificity which we Romanians get
harder!) is initiating this Centre for Initiation of Young
Olympics to Scientific Research in our institute.
I add and other motivations:
- Scientific research is an area that requires a
special training, at least in the methodology.
- A different mentality than that in which we float
randomly most of the time.
- It is for the elite to strengthen their (longer
recognize the current critical mass consisting of
mediocre and below-mediocre man supports hardly the
elite, but this was not always in Romania; between
the world wars we had the elite who practiced even
patriotism without outbid!).
- The unconditional obligation to offer all possible
good. And therefore sustaining today these kids, they
will reach competitive professional results and that
means that the community makes its duty.
- To make it possible to continue the effort of
these special children (for which a baccalaureate is the
main project) to curiosity and competition.
