Abstract:
Ternary melt-castable explosive compositions designed for elaboration by pouring, containing 2,4dinitroanisole (DNAN) as a castable binder, were prepared and tested. High energetic components were:
hexogene (RDX) and 3-nitro-1,2,4-triazol-5-one (NTO) or 1,1-diamino-2,2-dinitroethen (FOX-7), with
different crystal sizes. Compositions which at the beginning seemed to have an optimal pourability were
chosen to following research. The impact sensitivity of those compositions was measured. Then, for the least
sensitive compositions, the dependence of their dynamic viscosity on temperature was determined. It was
found that the impact sensitivity of compositions containing FOX-7 is considerably higher than the
sensitivity of those with an addition of NTO, and is comparable with the impact sensitivity of some
secondary explosives that are known as too sensitive to be used individually. No close dependence of the
impact sensitivity on the content of crystalline fractions of NTO or FOX-7 was observed. It was noticed that
2,4-dinitroanisole is a quite good solvent of hexogene.

NANOCRYSTALLINE FERRIC CATALYST VERSUS NICKEL-BASED CATALYST IN
CRACKING OF METHANE REACTION

Abstract:
Hydrogen is regarded as one of the most promising sources of energy in the future. Furthermore, it is
widely used in industry as a substrate for chemical synthesis. Currently, the most common method of
hydrogen production is steam reforming. Unfortunately, the presence of carbon monoxide in the obtained gas
stream causes that hydrogen is not suitable for direct use, which means that complicated separation methods
must be used. Consequently, it seems natural to pay attention to a direct way of methane decomposition:
CH4 ↔ C(s) + 2H2 ∆H = 75,6 kJ/mol
(1)
The direct products are gaseous hydrogen and carbon in the solid phase. Therefore, the selection of
a proper catalyst is an important issue. According to the literature iron group metals (Ni, Co, Fe) show the
highest activity in the cracking reaction of hydrocarbons. Ni-based catalysts showed the highest activity, as
well as cobalt. Ferric catalysts show
significant resistance to high temperatures and are relatively
inexpensive. Unfortunately, they have the lowest activity of the above mentioned metals. The carrier
catalysts did not turn out successful; therefore, it was decided to use a nanocrystalline ferric catalyst
promoted by oxides of aluminum, calcium, potassium and cobalt. The results of the research were compared
with the nickel-based catalysts, commonly used in the cracking of methane reaction.
Activity tests were carried out in a quartz reactor. The concentration of outlet hydrogen was determined
by gas chromatography with a thermal conductivity detector. The nanocrystalline ferric catalyst showed high
activity and significant resistance to carbon deposition. The reaction yield in the direction of hydrogen
acquisition was 87% and maintained for several hours. 64% is the highest concentration of hydrogen for
a nickel-based catalyst that was achieved.
The ferric catalyst has higher activity and longer reaction time than nickel-based catalysts. It can be an
alternative route of hydrogen production by cracking of methane reaction.

NUMERICAL AND EXPERIMENTAL ANALYSIS OF BULLETPROOF THE TEXTILE
BALLISTIC PACKAGE MADE OF PARA-ARAMID FIBERS

Abstract:
The aim of body armor is to ensure effective protection of human against various types of bullets.
Stopping a bullet is not possible through the use of single layers of ballistic materials. Therefore, it is
important to create a multi-layer systems which are defined as "soft ballistic".
The simulation research of the impact bullet 9x19mm Parabellum in the ballistic package that has
parameters Twaronu CT709 was carried out. The results of numerical research was verified with
experimental results conducted in the Ballistic Research Laboratory at the Lodz University of Technology. In
the first stage of the numerical research the deformities of bullet were analyzed. The geometric model and
material model of bullet 9x19 mm Parabellum were developed. In the beginning bullet was modeled as
a single structure which takes account only lead core bullet. Currently, the geometric model except for the
core, also takes into account bullet jacket made of ballistic brass. After the adoption of material models were
analyzed by using finite element method, the deformation of bullet during impact in non-deformable plate.
The verifications model was performed based on experimental research published in the literature.
In the next stage of work, verification of the simulation results was carried out with experimental
research of the bullet impact in the ballistic package. The geometrical models 30x30cm layer were prepared,
which allowed for the development of packages: 6 layers, 8 layers, 10 layers, 12 layers, 16 layers and 24
layers. For each of these packages were researched at a predetermined velocity of bullet 366.9 m/s (as in the
experiment) residual velocity, energy dissipation, and the maximum height of the cone.

BINDING OF 3,5-DIIODOSALICYLIC ACID BY BOVINE SERUM ALBUMIN (BSA) USING
MICROSCALE THERMOPHORESIS AND X-RAY CRYSTALLOGRAPHY

Abstract:
Serum albumin is the most abundant protein in the mammalian blood. It is synthesized in the liver and
exported to the circulatory system as a non-glycosylated protein. Albumins bind various endogenous and
exogenous ligands and are used as model proteins for many biochemical, biophysical and physicochemical
studies. The albumin - ligand interaction plays an important role in pharmacokinetics and pharmacodynamics
of the drugs.
X-ray crystallography is a powerful method allowing to visualize the three dimensional structure of
proteins at the atomic level using strong and bright synchrotron radiation. This technique provides
information about the binding sites, the number of bound molecules in the protein - ligand complexes.
Microscale Thermophoresis (MST) is a recently developed technology, which enables measuring a wide
range of biomolecular interactions under close to the native conditions. Factors that make MST more
preferred in comparison to other popular techniques, such as surface plasmon resonance (SPR) and
isothermal titration calorimetry (ITC) are low sample consumption and fast measurements. Both techniques,
crystallography and MST complement each other and thus make the results more accurate.
The study involves the analysis of interaction between bovine serum albumin (BSA) and 3,5diiodosalicylic acid (DIS) in complex using MST. Crystallographically, there are four DIS molecules present
in the BSA-DIS complex (PDB ID: 4JK4) [1]. Interestingly, MST measurements have shown for DIS
molecule three binding sites. The experiment was aimed for a qualitative evaluation of the BSA-DIS
interaction.

Abstract:
Emulsions are the heterophasic systems of liquid-liquid type, wherein each of the two immiscible liquids
is different from the point of view of chemical composition and physical properties. Emulsions are specific
mixtures, in which one phase is dispersed in the other, in the form of small droplets. The most common
example of immiscible liquids are water and oil. For this reason, in the literature, the suitable phase of
emulsion systems, called with the term "water" or "oil", regardless of the actual chemical composition.
There are two types of emulsion: oil-in-water (O / W), in which water constitutes the continuous phase
and the organic liquid droplets of the dispersed phase and the water-in-oil emulsions (W / O), wherein the
continuous phase is a organic liquid (oil) and the disperse phase is water.
To form an emulsions it is also necessary substance called emulsifier, which ensures their stability.
Delamination processes of the emulsion are complicated. A measure of the stability of the emulsion is the
resistance to the following phenomena: cream, flocculation, coalescence.
In this work have been presented a investigation of creaming process of the three types of emulsion: oil /
water with gelatin as an emulsifier, diesel / water with gelatin as an emulsifier and mixtures of diesel-oil /
water with gelatin as an emulsifier. Attempt was made to verify the suitability of the capillary model of the
granular layer to describe the rate of this process. Capillary model assumes that the granular layer may be
considered as a system of interconnected tubules of complex shape, by which followed fluid flow.

Abstract:
Crosslinking is a fundamental and indispensable process in polymer technology. Most commonly used
method
is
thermal
crosslinking,
in
which
energy
of
activation
is
transferred
in a form of heat. An interesting alternative for the thermal method is radiation crosslinking, which uses
high-energy radiation to generate radicals in the polymer matrix. Due to the fact, that ionizing radiation
affects all components of the material, proportionally to their electron participation, the additives
incorporated into polymer matrix can have significant influence on radiation crosslinking. The processes
induced in matter by ionizing radiation are very complicated and their mechanisms have not been entirely
elucidated.
Influence of dicumyl peroxide (DCP) on the radiation crosslinking process of elastomer composites was
investigated. The object of study was acrylonitrile-butadiene rubber (NBR) filled with fumed silica and
carbon black, and with additive of DCP in amount of 1,5 phr. As reference, corresponding composites
without DCP in composition were used. No influence of DCP on crosslink density was observed. Possibility
to additionally thermally crosslink the rubber composites, after their prior exposure to ionizing radiation was
proved, what indicated on retention of DCP crosslinking activity after the process of composites irradiation.
Mechanical properties, determined in static strength tests, are reported.

Abstract:
4-Methylidenepyrazolidin-3-ones 1 constitute a subgroup of a larger, biologically important class of
compounds - α-alkylidenelactones and lactams 2 displaying broad spectrum of activities, from cytotoxic,
anti-inflammatory and cardiovascular to antibacterial and antifungal [1]. In our laboratory for some time we
have been focused on the synthesis of α-alkylidenelactones and lactams 2 as cytotoxic agents. Many
compounds obtained in our laboratory, such as 4-methylideneisoxazolidinones 3 containing additional
nitrogen atom in the lactone ring, turned out to be highly potent against several cancer cell lines [2].

Abstract:
Many biologically important small molecules, hormones, drugs, etc. contain in their structures halogen
atoms: chlorine, fluorine, bromine and iodine. These atoms, due to the relatively large van der Waals radii
and unique charge distribution, arise as important factors, which actively participate in recognition of the
specific binding sites in polypeptide chains. Therefore, they can be situated not only in the hydrophobic
compartments of the protein where are stabilized by van der Walls forces, but they can also act as a donor in
halogen bonds or acceptor in the formation of hydrogen bonds with polar residues of protein.
The serum albumin, main transport protein of human plasma is one of the target protein taken under
consideration during drug design process. In this heart-shaped helical protein many binding pockets can be
found. These cavities are very complexed and are able to bind diverse groups of compounds which can be
crystallographically proved.
In Protein Data Bank there are 20 crystal structures of the serum albumin complexes with 13 different
halogenated aromatic compounds: drugs, drug-like molecules and one hormone - thyroxine. Six of them
contain fluorine atoms, two poses chlorine and five are iodinated. None of the ligands are substituted with
bromine.
This research will highlight the character of the interactions between halogen atoms and serum albumin.

Abstract:
Sulfur modified nucleosides are important, natural components of tRNA molecules, vital for their
biological functions in the cell.1 Most of them are 2-thiouridines (S2U, 1), often carrying an additional side
chain at the C5 carbon of the heterobase. Recently, some evidence has been reported that tRNA molecules are
involved in the cellular response to various oxidative stress conditions2. Susceptible to oxidation 2-thiouridine
units in tRNA may be a primary target of oxidative attack of reactive oxygen species.
Herein, we present the results of desulfuration of 2-thiouridines (1 a-d) under model in vitro oxidative
stress conditions.

The reactions of 2-thionucleosides (1 a-d) with hydrogen peroxide (H2O2) were used as the model
conditions of oxidative stress in the cell. The reactions were carried out either in water or in buffered
solutions (pH 6-8)3. The reaction progress was monitored by 1H NMR. The obtained results, showed that the
proportion of the products, a product of oxidative desulfurisation (2 a-d) to the oxidation product (3 a-d)
depends significantly on the pH of the reaction solution and on the influence of 5-substituent to electron
density in the heterocyclic base.

Abstract:
Opioids, including morphine and related synthetic compounds, are the most effective analgesic currently
used. However, they cause side-effects for example they interfere with the motility of the gastrointestinal
tract or cause respiratory depression. Furthermore, after using them for several weeks as painkillers,
tolerance may be developed, needing to use more to obtain the same pain relief. In addition, patients may
develop some degree of physical dependence. These drawbacks have prompted researchers to look for new
compounds that are sufficiently potent but do not cause tolerance, addiction or the side-effects.
With the discoveries of opiate receptors and the endogenous opioid peptides Met i Leu-enkephalins in
the mid-1970s, a new era in neurobiology began. Numerous chemical modyfications have been carried out
on endogenous opioid peptides in order to determine the structure-activity relationships of these opioid
ligands and develop more potent, more selective, but nonaddictive analgesics. One of the most promising
ways of developing new opioid analogs is the synthesis of compounds containing two active elements in one
molecule.
Among the bivalent ligands, biphalin was found to be a very effective compound, with strong analgesic
activity. Biphalin is an octapeptide with a dimeric structure based on two identical pharmacophores, derived
from enkephalins, joined “tail to tail” by a hydrazide bridge. Also molecules containing 4-anilidopiperidine
moiety such as fentanyl (N-phenyl-N-piperidin-4-yl-propionamide) posses antinoception properties. Fentanyl
analogs in combination with a fragment of enkephalins have a good penetration through the blood-brain
barrier and their action last longer.
The synthesis of new biphalin and fentanyl-enkephalin analogues modified with non-coded amino acids,
the synthetic strategy as well as opioid activity will be presented.

Abstract:
Nanocellulose is a polymer composed of cellulose nanofibers whose functional properties are determined
by the structure of nanofibrils. Natural fibers, for which at least one of dimensions is up to 100 nm, display
properties of both macroscopic substances and specific features of nanomaterials. The higher surface area of
nanocellulose compared to its native form results in stronger interactions with other substances, e.g. it binds
various nanomolecules. Furthermore, nanocellulose matrices contain nanopores while nanocellulose
suspensions or the polymer contained in nanocomposites is transparent [1,2].
Presented study aims at the development of a method of nanocellulose fabrication from plant biomass.
This nanocellulose will be used to produce biodegradable plastics and components used in textiles
fabrication.
The cellulose nanostructures will be obtained from plant biomass by a top-down method based on
physical, chemical and enzymatic (cellulases, pectinases, xylanases and ligninases) refining methods.
Currently conducted experiments have been focused on selection of suitable conditions of mechanical
biomass pretreatment and enzymatic degradation of lignincellulose. Fiber dimensions are controlled using
optical microscope (Olympus BX-51) and CellSens software. Released nanocellulose particles content is
estimated based on reducing substances determination.

Abstract:
Biomass utilization as a renewable carbon source has potential to replace petroleum for production of
chemicals and fuels. γ-Valerolactone (GVL) is one of the platform molecules derived from biomass, which
can be used for high-value chemicals and biofuels synthesis [1]. GVL can be obtained by hydrolytic
hydrogenation of lignocellulosic biomass. A variety of catalytic systems have been developed for the
production of GVL. Ru-based catalysts were confirmed as most active [2]. These catalysts are easily
deactivated, therefore their properties were modified through the use of various supports. The most
promising support, due to its stability and high resistance to decoking, is zirconium oxide (IV) [2,3].
The aim of this work was development of Ru catalyst supported on various ZrO2- more stable and active
in hydrolytic hydrogenation of biomass for γ–valerolactone. Reaction was carried out in two stages. In the
first step through biomass hydrolysis levulinic acid (LA) was obtained, after that LA was hydrogenated to
GVL.
The hydrogenation of LA to GVL was conducted in the presence of Ru catalysts supported on different
zirconium oxides (IV). The preparation procedure had a significant impact on the physicochemical properties
of the catalyst: the highest yield of GVL (26%) was obtained for catalyst with large surface area (152 m2/g),
and small crystallite size of Ru (5.9 nm ), with tetragonal phase of ZrO2.

Abstract:
The aim of this paper was to determine the relationship between thermal properties of aluminised basalt
and glass fabrics. Research on the thermal insulation was necessary to verify a thesis about the possibility to
replace glass fabrics by basalt fabrics. Replacement of glass fabrics by basalt fabrics may reduce a cost of
production of clothing protecting against the heat radiation. Not only the price is in favor of fabrics made
from basalt fibers, but mostly the high resistance to exposure on the high temperature. Materials destined for
the protective clothing were tested on the device Alambeta Sensor Company (Czech Republic). The device
enables to assess the heat flux transport through textiles in the defined conditions. Tests carried out on
aluminised glass fabrics allowed determining the boundary values of the thermal insulation. These values
were used as a basis for determining the possibility of replacing the aluminised glass fabrics by aluminized
basalt ones.

Abstract:
In the biotechnology, there are three types of cultivations process due to their continuity. In Batch
Cultures, all necessary medium components and the inoculum are added only at the beginning of the process
and their concentrations are not controlled but are allowed to differ as the microorganisms take them up.
Both types of products, intracellular and extracellular, are harvested only at the end of the process.
Continuous Cultures are known as an operations in which, one or more feed streams containing the
necessary nutrients are fed continuously, whilst the effluents are continuously removed. The culture volume
is kept constant. This type of cultivation is the most popular in the chemical industries, however, this
method, has one major flaw. The cultures were carried out by this method are more susceptible to infection.
The third type of fermentation, which combines features of the two previous ones is Fed-Batch Cultures
(FBC). A FBC is a semi-batch operation in which the nutrients needed for microorganism growth and
product formation are fed either intermittently or continuously via one or more feed streams during the
fermentation [1].
Many kinds of cellulolytic enzymes are produced by submerged cultivation (SmF) or by solid state
cultivation using moistened cereals and agricultural wastes. As the microorganisms in solid state
fermentation (SSF) grow under conditions closer to their natural habitats, they may be more capable of
producing certain enzymes and metabolites which usually will not be produced or will be produced only with
low yield in a submerged culture [2].
Based on the above properties, a method to transfer the positive properties of FBC to SSF, was
investigated. The presentation will present the result of the studies on selection of the most appropriate
multienzyme preparation containing cellulases applicable to releasing of nanofibers from lignocellulosic
biomass. This study is supported by project 01.01.02-10-123/09 co-financed from funds of European
Fund of Regional Development within Operation Program Innovative Economy 2007-2013.

Abstract:
Base-modified nucleosides with azide group are of great interest because of their applicability in the
synthesis of new nucleoside analogues using “click chemistry” methodology. 2-Azidouridine (2-azidoU),
with azide group in place of the carbonyl function of canonical uridine, belongs to this group of nucleosides
with interesting chemical properties.
The main goal of my studies was to perform conformational analysis in crystal and in solution for 2azidoU by means of X-ray or high-resolution NMR methods, respectively. It was especially important to
determine the structure of modified heterobase moiety (possibility of azide-tetrazole tautomerism), which
may affect the reactivity of nucleoside.
The rentgenostructural investigation of 2-azidoU crystals proved that this nucleoside crystallizes in
monoclinic system and exists in tetrazole tautomeric form. Nucleoside molecule adopts C3’-endo
conformation of sugar moiety, anti conformation around N-glycosidic bond and trans orientation of 4’hydroxylmethylene group.
Conformational analysis of 2-azidoU in aqueous solution (1H NMR, 13C NMR, HSQC, HMBC) revealed
that the major conformation of nucleoside is C3’-endo, anti, gauche (+). Spectral characteristic of 2-azidoU
(NMR, IR) confirmed that also in solution this compound occurs in tetrazole form.
Presented study are important for better understanding the correlation between
the nucleobase
modification and overall conformation of nucleoside unit.

Abstract:
Corrugated board is a common product used for packaging and transport. Different kinds of corrugated
board enable customizing its properties for many applications. Composed of facing and fluting paper plies,
this packaging material provides a protective barrier.
Many different factors determine the quality of corrugated board. Since the most popular single wall
corrugated board exhibits the lowest mechanical properties, multi-layer corrugated board has been
developed. The aim of author’s research is to find the compromise between strength, basis weight and plies
position of multi-layer corrugated board. Application of research such as ECT (Edge Crash Test), tensile,
compression test and Young modulus determination in the paper plane of each of the plies of corrugated
board is to determine the properties of four-ply, six-ply and other multiple-ply corrugated board. The
different combination of fluting plies position and elimination of intermediate plane ply is one of the
solutions to improve mechanical properties and also is part of the research.

Abstract:
Emulsions are stable systems consisting of at least two phases of which one of them, usually called the
internal phase, is dispersed as droplets in the other phase, called the external phase. Unlike as in suspensions
(solid colloid particles) emulsions have a few standing out properties which results from a smaller difference
of densities between the two phases. Such substances are present in the industry and in the natural
environment and are divided into two types of emulsions: O/W (oil in water) and W/O (water in oil).
Maximum stability of emulsions in something that is usually being sought. But in such domains as
environmental engineering or the petrochemical industry the most important issue could be the assurance of
the fastest and most accurate phase separation that is possible in regard to sewage or water purification, or
dehydration of extracted petroleum. Flotation and creaming are the most basic processes concomitant in
phase separation.
Creaming is a process in which droplets of the dispersed phase float up to the surface of the emulsion
leaving a aqueous phase behind. The behavior of a creaming emulsion may have different forms depending
on the concentration, dispersibility of the droplets and intermolecular interactions. Flotation is a process used
to separate the phases, especially to separate the solid phase from the liquid phase or liquid phase from the
other liquid phase. Substances lighter than water – like fat – have the tendency to form a coat on the surface
of the water, where it can be easily removed.
In this work there are described attempts to analyze the course of the creaming and flotation processes
using a computer software Ansys Fluent 14.0. Tests were conducted for a bi-phase and a tri-phase system.
The first simulation was conducted for a bi-phase system with two liquids: water and petroleum, in which the
solution concentration was 10%. The second simulation was conducted for a tri-phase system. The emulsion
consisted of water, in which petroleum and air (3rd phase) were dispersed. The content of phases in the water
solution were 10% of petroleum and 10% of air.
Obtained results allowed to estimate the time needed for bi-phase and tri-phase system separation.
Conducted simulations showed the phase distribution of the particular ingredients of the mixture.

Abstract:
Sphingolipids belong to the most important constituents of the membranes of eukaryotic cells. Family of
this compounds play a crucial role in many essential biological process such as cell recognition, cell growth,
differentiation and apoptosis. Moreover, recent studies reported that sphingolipid participation in many of the
most common human diseases including diabetes, cancers, heart diseases or Alzheimer’s disease [1].
The basic structure of sphingolipids are ceramides which consist of long-chain sphingoid base backbone
linked to fatty acid via an amide bond.Differences in acyl chain length of fatty acids or sphingoid backbone
of ceramides can deeply modify their biological properties. Similar changes follow also from
the
substitution of sphingosine backbone in 4-position. This is a result of the close vincity of substituent into
almost all functional groups of sphingosine moiety which form biologically active center of molecule.
In recent years it has been interest in the synthesis biological active ceramides derivative 4-substituted
sphingosines.
Nikolova and Haufe studied the effect
of a fluorine substituent in the 4-position of sphingosine
backbone [2]. Surface/pressure isotherms and hysteresis curves ceramide and its 4-fluoro derivative showed
that the presence of fluorine leads to stronger intramolecular interactions between the hydrophobic chains of
neighbouring molecules. Moreover, 4-fluoroceramide exhibit to increasing stability of the monolayer at the
air/water interface.
It’s also known that methyl group in ceramide molecule can deeply modify its biological properties.
It has been found that 4- Z- and E- sphingosines to bring morphological changes in neuronal cells and
behave as a enzymatic inhibitors.

Abstract:
For many years, increasing attention is paid to the presence of bioactive compounds in the diet favorably
affecting the human body. Biologically active substances contained in the food considerably reduce the risk
of lifestyle diseases (diabetes, arteriosclerosis, cataracts, Alzheimer’s disease, Parkinson’s disease). These
beneficial biological effects are also attributed to flavonoid analogues and their metal complexes.
Flavonoids belong to a large group of polyphenolic phytochemicals possessing antioxidant properties,
significantly as a result of direct free radical scavenging. Their antioxidant behaviour is probably related to
their metal ion chelating ability using transition metals, mainly Fe(II), Fe(III) and Cu(II) which participate in
reactions generating free radicals. It is believed that metal-flavonoid chelates are more effective free radical
scavengers than free flavonoid ligands and successfully protect from oxidative stress.
The aim of this study was to compare the antioxidant properties of naringenin, its derivatives, and
complexes with copper(II) ions. According to obtained results, metal complexes with naringenin are
supposed to be better radical scavengers than parent flavonoid. Likewise, copper complex with naringenin
analogue with thiosemicarbazide has proved stronger antioxidant activity than free analogue.
Flavonoids present various benefits to human health, attributable to their metal-binding and antioxidant
activities to certain extents. Total antioxidant power is often more purposeful to estimate health favorable
effects due to the cooperative action of antioxidants.

Abstract:
Deltorphin I and dermorphin are opioid heptapeptides that have been isolated from the south American
frog belonging to the genus Phyllomedusa (Fig. 1). Deltorphins contain a uniquely high selectivity to δ
opioid receptors whether dermorphin shows remarkably high µ selectivity [1,2].

When injected into the brain of mice or rats deltorphins I produce analgesia, locomotor stimulation, and
motivational rewarding without the development of physical dependence or respiratory depression. With
a high affinity and intrinsic activity for µ opioid receptors, dermorphin shows a strong and prolonged
antinociceptive effect with various injection routes.
The use of peptides as drugs are limited because of their rapid biodegradation under action of proteolytic
enzymes and low selectivity connected with high conformational freedom. These disadvantageous properties

prolonged action. A convenient methods of conformational freedom restriction is incorporation
α,α-disubstituted amino acids. In our group we develop efficient method for the synthesis of multifunctional
α,α-disubstituted glycines from easily accessible α-alkylserines. Cyclization of N-protected α-alkylserines to
corresponding β-lactones and then ring opening with various nucleophiles (-N3,- -N
) produced
N-protected α-alkyl-β-azido(sec-amino)alanines, the building blocks suitable for direct incorporation into
peptides [3].

Abstract:
Cardamom is commonly known as the “queen of spices” and the third most expensive spice, after saffron
and vanilla. Cardamom comes from south India and Sri Lanka, but this plant is also cultivated in Guatemala,
Costa Rica, and Morocco. Today, Guatemala is one of the most important producers of this spice which is
completely grown for export.
Cardamom occurs in dried form, which can be the main reason for their microbiological contamination.
Nevertheless, many spices, including cardamom, are grown and harvested in poor sanitary conditions and in
warm and humid regions. Therefore, the main purpose of the food industry is to find an innovative
decontamination technology which meets the consumers’ demand of fresh and safe products. The promising
perspectives gives ozone as a decontaminating agent.
The obtained results, preceded by a triple ozone decontamination at 24-hour intervals under conditions as
follows: ozone concentration 160-165.0 g/m3; flow rate 0.1 L/min; time 30 min, indicate changes in the total
polyphenol content, antioxidant activity, and ferric reducing antioxidant power. Next to antioxidant assays,
microbiological profile was determined. The study confirmed that ozone is very effective in reducing the
fungal count as well as total mesophilic count.
The study showed that ozone decontamination allows to obtain a microbiologically pure product with
a similar composition of essential oils, but simultaneously with losses of polyphenolic compounds.

DYES DERIVATIVES OF 1-AMINOANTHRAQUINONE AS PHOTOINITIATORS FOR
RADICAL POLYMERIZATION

Abstract:
In recent years, due to the tremendous increase in demand for initiators that are capable of initiating
radical polymerization with visible light, novel and effective photoinitiators are sought [1]. One method is
a photoinduced electron transfer process, which involves the use of radiation-absorbing dye and the
co-initiator, which disintegrates into radicals via electron transfer process [2,3] . The second solution is the
synthesis of chromophoric systems, which contain in their structure a carbonyl group and the substituents as
a hydrogen donor. These one-component systems act as initiators of the type II [4.5] . As a chromophore in
these systems thioxanthone is mainly used, and the resulting structures have the absorption bands around
400 nm.
Therefore, an attempt was made to develop efficient methods of synthesis of new photoinitiators capable
of initiating radical polymerization under visible light raging 400 - 600 nm.

Abstract:
Isotope effects are a mechanistic phenomenon wherein isotopically substituted molecules show the
different behavior in comparison to unlabelled systems. Isotope effects are providing suitable tool for
investigating chemical mechanisms and also describing interactions between reactants, especially in case of
enzymatic systems.
Herein, we are focused on binding isotope effects, BIEs, that can be used to understand interactions
between reverse transcriptase, RT, one of three HIV-1 enzymes, and their non-nucleoside inhibitors,
NNRTIs. Based on obtained BIE values we are able to identify the most important interactions and
rationally design new inhibitors.
Additionally, we discussed kinetic isotope effects, KIEs, that can elucidate mechanism of proteolysis
catalyzed by HIV-1 protease, PR. The magnitude of theoretical KIEs in comparison to experimental values
allows study of the changes that occur during conversion from reactant complex to transition state, TS, as
well as provide direct information of TS geometry. According to transition state analog, TSA, theory the
geometry of rate-limiting transition state indicate the most favorable structure of the inhibitor.

Abstract:
Uracil 1 and its derivatives are a very important group of organic compounds. They occur naturally in
ribonucleic acids and are used in the synthesis of active enzyme inhibitors, oligonucleotides and nucleosides.
5-Fluorouracil 2 and its derivatives, especially tegafur 3, are used in antitumor therapies. Sparsomycine

Abstract:
Avidin is the biotin binding protein and belongs to the calycin protein structural superfamily. This
protein is the object of various biochemical investigations because of its unique binding properties with
biotin that is one of the strongest interactions in nature (Kd≈10-15 M). This interaction is several orders of
magnitude higher than in the typical antigen-antibody
antigen antibody complexes. For this reason avidin-biotin complex is
extensively used in the life sciences.
Various biotin derivatives were synthesized, which can be used in the form of complex with
wit avidin in
biotechnological and biochemical studies, but also as the carriers for drug delivery. Here, based on X-ray
crystals structures deposited in Protein Data Bank, I would like to compare the avidin interactions with
different biotin derivatives.
Structural studies will allow to investigate the binding of ligands in the macromolecule binding pocket
and describe how it is connected to the constitution of the ligand and the conformational adaptation of
protein structure. This knowledge can be used in the future to develop the technology based on the studied
complexes.

THE ROLE OF “INTENT” IN PREDATORY PRICING CASES IN THE EUROPEAN
UNION
PhD Student: Krzysztof Krzystek
Supervisor: prof. dr hab. Maria Królikowska-Olczak
Chair of European Economic Law
e-mail: [email protected]
Abstract:
Predatory pricing is a pricing strategy where a product or service is set at a very low price, intending to
drive competitors out of the market, or create barriers to entry for potential new competitors. In the EU it has
been traditionally considered a form of abuse of Art. 102 TFEU, which deals with the abuse of a dominant
position. Contrary to other types of abuse of a dominant position in which the ECJ has exclusively used
objective criteria, in predatory pricing cases the ECJ has also included the subjective criterion of intent.
In his speech the author presents the recent developments in the jurisprudence and the approach to the
inclusion of this subjective criterion. He demonstrates how intent was proven in the past cases and argues
why the departure from this criterion is a necessary step forward.

The effectiveness of a specific therapy depends not only on pharmacological activity, but also the form
of the active pharmaceutical ingredients (API). Significant attention has been focused on the development of
more bioavailable, water soluble, new APIs with specific physicochemical properties. This goals can be
accomplished by using inter alia micronization process, incorporation of APIs into Drug delivery Systems
(DDS) and by forming the salts of drugs or cocrystals.
In the first part of the presentation the results included method to formulate drugs/Mesoporous Silica
Nanoparticle (MSN) systems using Ibuprofen as Non-Steroidal Anti-Inflammatory Drug will be shown. The
applicability of NMR techniques in solid state (SSNMR) will be also described. Based on that research, the
methodology, which provides important information for structure, molecular dynamics and interactions
analysis of ibuprofen/MCM-41 will be shown.
The second part of the talk method the formulation of cocrystals made up of two or more components in
a definite stoichiometric ratio will be discussed. Cocrystals have dramatically different properties,
e.g. solubility, melting point ect. In this project the benzoic acid/2,3,4,5,6-pentafluorobenzoic acid
(BA/FBA) cocrystal, obtained by grinding and melting methods was used. After precisely structural analysis

THE IMPACT OF THE HYBRID METHOD OF APPLICATION OF LIQUID AND
COMPRESSED AIR ON SURFACE QUALITY OBTAINED IN THE PROCESS OF GRINDING

Abstract:
The aim of this scientific research is identification of the impact of hybrid method of supply of cutting
fluid with minimal oil mist consumption that allows adequate lubrication of the friction in the grinding
process. At the same time the goal of this research is to identify the optimal application method of liquid by
additional influence of the factor in a form of compressed cooled air (to a temperature of -5 °C) which
favours the condition of the top layer. Grinding processes without the participation of working liquid carry
many negative effects as increased strengths, higher temperatures and shortening of the period of durability
of the blades, which in turn raises the cost of working operations.
The method and effective application of minimum quantity of lubrication and machining of compressed
air to a cutting zone faces a number of difficulties in the process of grinding. Among others a high speed of
the grinding wheel peripheral with the likes of several meters per second and connected with that air flow
can significantly reduce the effectiveness of lubrication of both the work surface grinding wheel and the
surface being machined. The increase of the participation of the compressed cooled air itself causes
a thermal shock to the grinding wheel. The idea to implement a hybrid method of grinding of the wheel and
to cool the workpiece requires a design solution to insert both factors into the grinding area as well as the
modification of the machine in order to control the order of administration of listed factors depending on the
direction of the movement of the workpiece. The aim is to ensure the efficient lubrication of the grinding
wheel, while ensuring cooling in order to avoid deformation of the workpiece and adverse effects of heat
influences in the top layer at the same time. For the purpose of this research I have used a device producing
the oil mist - Microjet, a dynamometer, a special vehicle unit registering changes of deformation and
extensions and a device for measuring the surface roughness.
The results of the research should contribute to wider spread of a hybrid method of application of both
factors during the grinding process, and replacement of classical cooling with a low cost method ensuring
a proper condition of the top layer in particular of compressive own tension without burns and tempering of
the top layer.

Abstract:
Artemisia vulgaris L, commonly known as mugwort, is a perennial plant widespread all over Europe,
Asia and North America. The aerial parts are used in traditional medicine and as a tonic for vital organs and
various disorders. A. vulgaris essential oil is economically important due to its insecticidal and antimicrobial
properties. The chemical composition of the essential oil from aerial parts of mugwort growing in different
parts of the world has been reported. Wide variation in the qualitative and quantitative composition of the oil
has been observed that depends upon the origin, vegetation stage and plant source organ.
Apart from essential oil during hydrodistillation of mugwort hydrolate can be obtained as by-product.
On the contrary to mugwort oil, no reports have been found on mugwort hydrolate composition..
The aim of present study was analysis of chemical composition of essential oil and hydrolate obtained
from aerial parts of mugwort in the same cycle during 40 min hydrodistillation process. Comopsition
of industrial product was compared to that of essential oil isolated in laboratory by hydrodistillation using
Clevenger-type apparatus. Volatile components from hydrosol were isolated by liquid-liquid extraction using
diethyl ether. Qualitative and quantitative analyzes were made by GC-MS methods.
The essential oil produced in industrial-conditions was composed mainly of sesquiterpene hydrocarbons:
(E)-β-caryophyllene, germacrene D, and α-humulene. On the other side, vulgarone B, sabinene, and
1,8-cineole were predominant constituents of laboratory-oil.
Fractions of hydrosol showed significant differences in the chemical composition, moreover majority
of them contained as main compounds monoterpene alcohols:. terpinen-4-ol, borneol, and α-terpineol.

Abstract:
Oxidation of carbon monoxide is an important reaction in processes related to environmental protection.
The purpose of this study is to define the mechanism of CO oxidation in the presence of a platinum catalyst
based on semiconducting oxides such as SnO2, TiO2, containing isotope 18O in their structure. TOF-SIMS is
a test method that allows an analysis of physico-chemical properties of solid surfaces. TOF-SIMS method
can be successfully used to identify chemical compounds. It also allows distinguishing different isotopes of
a given element.
The analysis of literature sources indicates the possibility that CO oxidation over Pt/SnO2 catalyst is
accomplished by oxygen present in the structure of the semiconducting oxide. Regeneration of the catalyst
support in the given mechanism involving atmospheric O2 occurs. The reaction mechanism described in this
way is called Mars and Van Krevelen mechanism (MvK). The subject of this study was an isotopic exchange
occurring on the surface of SnO2 in this process.
Preliminary studies were carried out using 1% Pt/SnO2 (18O) catalyst. The catalyst carrier (SnO2)
containing
18
O isotope was obtained by combustion of metallic tin in
18
O2 atmosphere. Then, the metal
phase (Pt) was deposited on the carrier by wet impregnation. In order to determine whether in the studied
reaction isotopic exchange 16O → 18O occurs, a gas containing 0.5 % carbon monoxide was passed through
the catalyst bed in a quartz reactor. The reaction product was absorbed in the CO2 absorbing solution
of Ca(OH)2. Thus, the chemical composition of the obtained precipitate CaCO3 was analyzed by TOF -SIMS
method. The collected spectra of characteristic secondary ions confirmed the presence of a heavier isotope
of oxygen in the test CaCO3 samples. This result indicates the relevance of the thesis that the reaction takes
place with the participation of oxygen present in the oxide semiconductor structure.

Abstract:
Emulsions consist of droplets of one liquid dispersed in another, which is considered as one phase.
Examples of such emulsions are: petroleum mixed with water, organic sewage, paints, glues, milk,
mayonnaise, crèmes, ointments etc.
Organic hydrocarbons are chemical compounds consisting only from atoms of carbon and hydrogen. All
of them have a primary carbon skeleton (carbon atoms tied to each other) and hydrogen atoms that are
connected to it. Hydrocarbons are the basic ingredient of petroleum, which is considered the main source of
hydrocarbons in the industry. The presence of large concentrations of petroleum-based substances in the
environment may lead to serious contaminations and is a direct threat for every living organism inhabiting
the contaminated area.
In result of physical or chemical interaction between water and petroleum-based substances emulsion is
brought to existence. Mechanical, chemical and biological methods of removing the contaminations of
single-phase nature were being developed for years. Unfortunately emulsification of hydrocarbon substances
with water is a very common occurrence. If this happens, separation of the phases is the first thing that
should be performed so the neutralization of the contamination may proceed any further – processing of the
emulsive systems is not advised. This calls for a need to elaborate a method for petroleum-base substance
separation from water. Creaming is one of these methods.
Creaming is a process in which droplets of the dispersed phase float up to the surface of the emulsion
leaving a aqueous phase behind. The behavior of a creaming emulsion may have different forms depending
on the concentration, dispersibility of the droplets and intermolecular interactions.
In this work there are described attempts to analyze the course of the creaming processes using
a computer software Ansys Fluent 14.0. There were tests conducted for a bi-phase system with two liquids
(water and petroleum), where the solution concentration was 5%. Obtained results allow to estimate the time
needed for the separation of the oil phase from the water phase. Conducted simulations showed the phase
distribution of the particular ingredients of the solution.

Abstract:
Dye-sensitized solar cells (DSSC) were demonstrated for the first time by Prof Michael Grätzel and their
called the “Grätzel cell” [1]. DSSCs have been attracting attention due to its low cost, easy and inexpensive
methods of fabrication and good power conversion efficiency. DSSCs are a potential alternative to expensive
silicon and thin film solar cell [2]. The dye is an essential component of DSSCs and its molecule is attached
on TiO2 surface by anchoring group i.e. carboxyl or hydroxyl groups.
The intention of this paper is to synthesize novel dyes (Fig. 1) with/without carboxyl group and to
evaluate these dyes spectroscopic properties. Their adsorption effectiveness on TiO2 were also investigated.
Results indicate that the dye with anchoring group shows the highest adsorption efficiency and the lowest
time of loading on TiO2.

Abstract:
Genetic polymorphism in other words, the existence of different variants of genes that are the result of
caused changes in the DNA sequence. These changes may occur spontaneously or may be induced by
various mutagenic agents. Breeding programs based on genetic polymorphic, include the identification of
genes and estimate the impact of the resulting gene mutations on productive traits of animals livestock.
For the detection of genetic polymorphisms can be used, inter alia, methods: PCR, PCR - RFLP
and SSCP. Polymerase Chain Reaction (PCR) is one of the most important methods of molecular
biology research. It is used to reproduce specific DNA fragments but can also be used to detect
polymorphisms type insertion/deletion. Procedure PCR - RFLP method is a modification of the
classic PCR method by using in addition a specific restriction enzyme. RFLP polymorphisms are
inherited sequence variants that appear creation or disappearance of places recognized by restriction
endonucleases. SSCP method is a technique in molecular biology based on native electrophoresis of
nucleic acids. This allows differentiation of fragments of the same length but different sequence.
Selection assisted for genetic markers gives the possibility of forecasting traits at a young age of the
animal. The selection takes into account the identification of polymorphic forms the genes in case
individuals intended for pairing. In the case of improvement of the animal production traits, the most
important are those genes and their metabolites, the activity disclosed in the various tissues.

Abstract:
Pathogenesis-Related Proteins (PRP) are a group of plant proteins produced in response to biotic or
abiotic stress, which may also be constitutively present in the cell. There have been classified 17 families of
PR-proteins, which vary by the structure and function. They are small proteins, which are able to function in
the cell in harmful conditions, such as different pH, high temperatures or the presence of proteolitic enzymes.
Not all of their functions are already known. The great attention is being paid to their antifungal activity,
as the majority of plant diseases is caused by fungal pathogens. Chitinases and β-1,3-glucanases are PR
proteins with high antifungal activity. They cause significant damage to the fungi cell wall and lead to its
destruction, especially when acting together. Pathogen resistant varieties of the plants constitutively have
higher concentration of this proteins. Also after the infection their level is rising faster, than in susceptible
plants. The enzymes of resistant plant have also been proven to release the elicitors from the fungi cell wall.
Determination of the activity of PR proteins is preceded by isolation the proteins from the plant material.
Their activity can be measured with use of indirect method using their substrates, with use of PCR method
by detecting the mRNA sequences responsible for their synthesis or by using the antibodies specific for
tested proteins.

Abstract:
Due to the high consumption of pork in Poland is important to its quality, taking into account the
physicochemical properties and technological usefulness. Pork meat must meet the criteria of maintaining
a healthy food. Significant impact on the quality of the meat have genetic and environmental factors and
interactions between them.
The classification of meat quality are its physical and physicochemical properties that allow
distinguishing normal meat from meat defects PSE (Pale, Soft, Exudative) and DFD (Dark, Firm, Dry).
Quality consists of a set of traits important for technological processing of pork as water holding capacity,
acidification(pH value), content of protein, intramuscular fat and tissues involved.
Water holding capacity determine the ability of absorption of the fresh meat to bind a certain amount of
added water. Measurement factor of water holding capacity may be the circle of moisture squeezed from
fresh meat on the paper or its electrical conductivity. A very important feature of pork is its acidification
(pH) measured after 45 minutes and 48 hours after slaughter. The meat during the maturing process is
acidified by lowering the pH value, while the most preferred for processing and consumption of pH 5.6-5.8.
Higher than 6.0 pH value of pork generally bind with a higher water holding capacity, have a better color and
taste. An important trait of meat is proteinand intramuscular fat content and their characteristics.
Define the traits and criteria for evaluation of pork quality has allowed to elaborate an instrumental
methods of its measurement. Apparatus method of measuring is acidification (pH), brightness of meat color,
conductivity, water holding capacity and tenderness of the meat. These methods are mainly adapted
fordetecting defects in the meat quality.

Abstract:
Functionally Graded Materials (FGMs) belong to a class of advanced materials characterized by
a variation in properties as the dimension varies. The overall properties of FGMs are unique and different
from any of an individual material that it forms. The concept of FGMs has been proposed to develop
heterogeneous materials with structure/properties that change gradually over their volume, in order to
achieve required functions of the final component.
This work presents an alternative approach based on a “combination” of Fe3Al intermetallics with an
appropriate conventional material (steel 316L) – in the form of the heterogeneous FGM fabricated by Laser
Engineering Net Shaping technique. LENS is the leading additive manufacturing technology utilizing a highpower laser together with the iron aluminide and stainless steel powders for the production of highperformance FGMs parts. The ability to fabricate heterogeneous metal-intermetallic materials with a three,
different production methods of chemical composition gradient 316L/Fe3Al was demonstrated. The first
FGM sample (in the cubic form) was obtained with using standard Data Matrix Code (DMC) automatically
generated by software (graded structure in Z direction). Other technological variants required manual
modification of DMC file. Finally two samples were manufactured with continuous and discrete chemical
composition gradient in radial and Z-direction respectively.

Abstract:
3-nitro-1,2,4-triazol-5-one (NTO) is a modern explosive compound. This material shows reduced
sensitivity to mechanical stimuli and shock initiation. In a past few years many derivatives of this substance
were described in the literature. NTO is also a valuable substrate for synthesis of azo- and azoxycompounds.
In this work we present results of systematic study on electroreduction of NTO in water/acid system.
Experiments were carried out using standard DC power supply with 12 V voltage and 4 A effective current
maximum. Graphite electrodes were used. Solid products were collected by filtration. Sensitivity to
mechanical stimuli of the products was investigated. The compounds were analyzed by Nuclear Magnetic
Resonance spectroscopy (NMR) and thermal analysis (DTA/TG) techniques. Morphology of the crystals was
evaluated with Scanning Electron Microscopy (SEM).

Abstract:
In recent years hybrid metallic-dielectric nanostructures are rightly receiving a great deal of attention.
Such materials called „core-shell“ are the combination of a spherical silica core and metalic shell. One of the
most interesting example of that structures is a combination of silica with gold (SiO2@Au) which shows
unique magnetic, biological, catalytic and optical properties. That features can be modified by selection of
materials and diameters of each compond. The structures exhibit so called plasmon resonance which is
associated with absorption of electromagnetic radiation in the specific range. The spectral position of the
resonance and the optical properties depend on the type of materials, their geometry and morphology.
In this work we obtained silica-gold core-shell structures. Synthesis of SiO2@Au was a two-step process.
Silica was functionalization by amino groups. Modification of silica surface was followed by applaying the
gold layer. Prepared materials were investigated by Scanning Electron Microscopy (SEM) and UV-VIS-NIR
spectroscopy.

Abstract:
Selected aspects of constituting of a surface layer of implants made of Ti alloy by a Laser Engineered
Net Shaping (LENS) method, have been shown in the present paper.
Proposed technology of the implants surface modification is based on the LENS MR-7 device, use in an
additive manufacturing of net shape, semi-finished components or in regeneration of damaged parts. Its
principles are based on a process of deposition of the powder material in the high-power laser beam area.
A method of forming a surface layer of Ti alloy based implants (developed in the Department of
Advanced Materials and Technologies MUT) uses the phenomenon of selective deposition of spherical
powders made of titanium alloy on the substrate. A proper control of working parameters at different stages
of the process provides a partial melting and metallurgical joining of the powder particles to the substrate.
Obtained surface modifications were analyzed in order to determine their structural and surface
morphology. A Light microscopy, a scanning electron microscopy, a X-ray diffraction and a non-destructive
X-Ray tomography were used during the evaluation. Results of performed technological trials have shown
that the proposed method allows formation of a surface layer of titanium alloy implant. Due to topographical
and morphological properties of newly formed functional surface layer, it is expected that the modification
will be beneficial in terms of the mechanical anchoring of the implant in the bone tissue.

Abstract:
Nitro derivatives of imidazole form an interesting group of high-energy materials. One of them is
4,4’,5,5’-tetranitro-2,2’-biimidazole (TNBI) which has high detonation parameters and could be used in
modern propellants or explosive compositions. Unfortunately it is very hygroscopic and can be used only in
form of salt. An important feature of this material is its low sensitivity to mechanical stimuli. In a past few
years a number of publications about TNBI and its salts have been released but still there are no results of
complex study on detonation parameters.
In this work an ethylenediamine salt of TNBI was synthesized. The structure of obtained compound was
confirmed with NMR spectroscopy. Thermal properties were investigated with DTA/TG analysis. The
detonation velocity of the salt was measured.

Abstract:
Nowadays, barley malt is the preferred brewing material. It results from its high extract content and high
enzyme activities. However, people suffering from celiac disease cannot consume beer produced from
barley, owing to presence of gluten. Recent studies have shown that oat in appropriate doses is tolerated by
people suffering from celiac disease. In medieval times, oats were traditionally used in brewing, but then
they have been forgotten. Oat beer could be attractive not only for people suffering from celiac disease, but
also for healthy consumers looking for new and interesting flavours. Oat has numerous health benefits. Oat
has less starch, more protein, β-glucan and fat compared to barley. However, many favourable properties of
oat from nutritional point of view can induce technological problems and compromise the quality of final
beer.
In this study the quality parameters of wort and beer produced entirely from oat malt as well as from
barley malt with a various contribution of unmalted oat (22,5 and 45%) were compared. In addition, the
influence of enzyme preparations Filtrase BR and Dex-Lo CL on technological parameters of wort was
assessed. Wort made from malted oat und unmalted oat exhibited a lower extract and free amino nitrogen
content (FAN) as compared to barley wort. Haze and high viscosity in wort and beer from oat malt, were
observed probably due to a higher content of protein and non-starch polysaccharides, such as β-gluten. The
use of unmalted oat also had an influence on lowering the concentration of higher alcohols and esters both in
oat and barley beer. Additionally, it reduced the concentration of ethyl alcohol in the final beer. The
application of enzyme preparations had a positive effect on: the increased content of extract and FAN,
a faster wort filtration due to the reduced viscosity. Our research indicated, that the addition of unmalted oats
should not exceed 20% both for beer from oat and barley malt.

Abstract:
The global industry is constantly looking for new design solutions and new materials which thanks to its
properties may improve the quality of manufacturing products, reduce the costs associated with the
manufacturing process, increase the flexibility of this process, etc. One of such materials is mineral cast.
Mineral cast (PC - polymer concrete) is a complex material composed of fine particles of inorganic
aggregates such as basalt, spodumene, fly ash, river gravel, sand, chalk, etc. connected together by
two-component, chemically hardened resin (usually epoxy resin). Mineral casts have much better dynamic
properties than the commonly used cast iron. The logarithmic decrement of damping of mineral casts is up to
10 times higher than in case of cast iron. Unfortunately, mineral casts have poor mechanical properties. The
tensile strength of mineral cast is about 10 MPa, while the compressive strength is about 100 MPa. In order
to verify the mechanical properties (tensile strength, compressive strength and Young’s modulus) of the
mineral cast material the study was carried out.
The material which was used for tests is mineral cast material offered by EPUCRET and commercially
available under the name EPUCRET 140/5. In order to carry out the research two types of samples have been
performed. The first type of sample was used in tensile test whereas the second one in compressive test.
Tests were carried out on ten samples.
Based on the survey it can be claimed that the literature data have been confirmed in case of the
mechanical properties of the mineral casts.

Abstract:
Juniper (Juniperus communis L) berries are usually consumed as dried. Therefore, the proper microbial
quality of them is needed before they go on the market. Thus, the decontamination process must be
conducted to assure consumers healthy and safe products. Several decontamination methods, which have
been considered in terms of their safety and effectiveness, have some limitations. That is why alternative
solutions are sought. Ozone as a strong oxidizer has an numerous applications in food industry and can be
used as a decontaminating agent.
Research material was delivered by herbal works KAWON–HURT, Gostyń, Poland. The study included
microbiological analysis, total polyphenol content (TPC), GC-MS analysis of essential oils (EOs), free
radical-scavenging capacity, and ferric reducing antioxidant power (FRAP).
The obtained results, preceded by a triple ozone decontamination at 24-hour intervals under conditions as
follows: ozone concentration 160-165.0 g/m3; flow rate 0.1 L/min; time 30 min, indicate changes in the total
polyphenol content, antioxidant activity, and ferric reducing antioxidant power. Next to antioxidant assays,
microbiological profile was determined. The study confirmed that ozone is very effective in reducing the
fungal count as well as total mesophilic count.
The study showed that ozone decontamination allows to obtain a microbiologically pure product with
a similar composition of essential oils, but simultaneously with losses of polyphenolic compounds.

Abstract:
Plants are the main source of natural antioxidants. Within the plant antioxidants phenolics can be
distinguished and classified as a diverse group of chemical compounds with different radical scavenging
capacity. Flax seeds are an abundant source of lignans, which have antioxidant properties and significantly
reduce the effects of free radicals.
Flax, Linum usitatissimum, is an annual plant and member of the Linaceae family. Flax is grown for
linseed oil and is mostly used as a source of fibers.
Flax is rich in fats (41 %), proteins (20 %) and dietary fibre (28 %). The composition of flax can depend
on growing conditions, seed processing, as well as genetics. Flax seeds with a lower protein content
generally have a higher amount of oil. Seeds of flax are the richest source of alpha-linolenic acid, lignans and
other nutritional components. Flax does not contain gluten and consequently can be applied in gluten-free
diets.
Flaxseed oil contains interesting bioactive compounds other than the fats. Next to tocopherols, vitamin
E analogs, anticancer and anti-cardiovascular disease agents, the polyphenolic compounds and flavonoids
exhibit therapeutic properties. Moreover, lignans, phenolic acids and flavonoids are in charge for the
decreasing rate of tumor growth and the decreasing incidence of breast, prostrate, and colon cancers.
The aim of this study was the comparison of the estimation of the total polyphenol content (TPC), the
free radical scavenging activity, and ferric reducing antioxidant power (FRAP) in extracts from defatted and
non-defatted flax seeds. The results clearly show the impact of fatty acids on the effectiveness of this
research.

Abstract:
Electrodeposited zinc coatings are widely used to protect steel against corrosion in various technological
fields. An anticorrosive properties of zinc deposit can be ensured by adding certain organic compounds to the
zinc bath. Benzylideneactone is the most commonly used brightener, which belongs to a group of
α,β-unsaturated
ketones.
During
the
zinc
electrodeposition,
benzylideneacetone
undergoes
an
electrochemical reactions causing the formation of various compounds, which contaminates zinc bath.
Therefore, these impurities should be removed.
Cyclic and differential pulse voltammetry was used to determine a reduction and oxidation potentials
α,β-unsaturated
ketones
1-(p-totyl)-1-penten-3-one
(PTP)
and
benzylideneacetone
(BDA).
The
measurements of voltammetric reduction were carried out at mercury electrode, whereas the oxidation was
performed at platinum electrode. In order to theoretically confirm their oxidative-reductive susceptibility,
HOMO and LUMO energies were calculated. The degradation of 1-(p-totyl)-1-penten-3-one by
photoelectro-chemical method in aqueous solution of KCl has also been studied. A reactor equipped with
a platinum cathode, titanium anode covered by TiO2 (70 %) / RuO2 (30 %) and UV lamp with an emission
spectrum at 254 nm was used in the experiments. The maximum mineralization (80 % for PTP and 98 % for
BDA) was achieved for the current intensity of 0.3 A and 120 minutes of the photoelectrochemical reaction.

Abstract:
The purpose of the research is to evaluate different formulas which are used to estimate the motorcycle’s
pre collision speed in perpendicular motorcycle-to-car accidents based on the wheelbase reduction and shows
relationship between motorcycle frontal damaged area and area of the car impact. As the area of the car
impact is engaged car “hard location” accepted as non-deformable barrier (such as car pillars, car front and
rear axles) and car “soft location” accepted as deformable barrier (such as doors, fenders). Those
relationships are used to estimate the motorcycle’s pre-collision speed in motorcycle-to-car accidents. The
evaluation used published data from group of different motorcycle crash experiments which was prepared by
the research institutes. The results so far have been collected in the graphs, where it’s easier to see that the
motorcycle’s pre-collision speed cannot be estimated with high accuracy. This is due to, among others, with
different coefficients of stiffness of the motorcycle structure as well as the local stiffness of the vehicle at
impact location. It Furthermore the results show the importance of undertaking further research in this area
and how it is important to approach each case individually, with due attention to minimize the risk of errors
in estimating of the impact velocity, how relevant to the knowledge of the truth about the traffic incident.
Researches in this area are also the basis for the development of motorcycle passive safety systems.

Abstract:
The purpose of the research is elaboration of a disclosure and ascertainment methodology of a type of
traces left by vehicles on a scene of an accident. Both the correct identification of the type of traces protected
on a scene of an accident and the possibility of establishing the intensification of the physical phenomenon
occurring in the time when they are formed are necessary to make an unambiguous reconstruction of the
accident in terms of forensic. Final result of an accident reconstruction is an expert opinion which should
clearly ascertain what failed in system human-vehicle-environment. In the research were analyzed the traces
of cooperation between the vehicles tyres and the asphalt surface. The stoichiometric composition of the
selected asphalt surface samples was set and the spectral analysis was done. In the researched groups of the
asphalt surface there were samples on which any traces of cooperation with the vehicles tyres was protected
and samples on which organoleptically recognizable traces of braking were protected (note: the specimens
had different coverage degree of the organoleptically evident traces). Structural analysis do not show any
important differences in the chemical composition of examined asphalt surfaces. Based on conducted
spectrometric test results analysis it was established that the surfaces of tested specimens are characterized
by different emissivity of the reflected radiation which depends on the coverage degree of the asphalt surface
sample with organoleptically evident skid marks. In the next stage of the study there are going to be
examined asphalt samples on which vehicles brake in a rapid way while sensory identified traces are not
protected.

Abstract:
The soils are porous structures of granular nature, namely solids are having a large number of its interior
space, which are filled with gas or liquid most frequently. These spaces are called pores. The granular layer
may be treated as a bundle of curving capillaries with flowing fluid through them. Model of capillary
network shall be considered as the ideal model of the pore structure, which is the recognition of the porous
layer, where can be investigated phenomena of two-phase flow systems of the oil-water or emulsion-water.
There are two opportunities for research: the real model or model based on the simulation. The purpose of
model of the capillary network is to reconstruct porous medium which contains small spaces filled with fluid
(e.g., gas, liquid, or a mixture of different liquids).
Transport of dissolved substances in porous media filled with liquid plays an important role in many
scientific and technological phenomena, among others in the transport of pollutants in the soil, nutrient
transport in the bones, blood flow in the blood vessels, the movement of minerals (e.g., fertilizer) in the soil,
in the techniques of secondary recovery of oil, hydrological research projects.

substances - oil using a low-viscosity substance - water. In the experiment, used such media as: silicone oil,
sunflower oil and the engine oil. These studies were carried out by replacing the actual structure of the
porous media systems connected in parallel capillaries. Attempted to describe the course of the processes

Abstract:
Water gas shift reaction is of great importance to the industry. It allows obtaining hydrogen and reducing
carbon monoxide at the same time. Hydrogen obtained in this reaction can be used for further processes such
as the preparation of ammonia.
The water gas shift reaction proceeds according to the equation:
CO + H2O ↔ CO2 + H2
∆H0298 = - 40.09 kJ / mol
Application of photocatalysts makes it possible to conduct this reaction without the use of high
temperatures. The initiation of the reaction occurs even at room temperature.
The ferrochrome catalysts can operate in the temperature range of 310oC to 450oC. The low temperature
shift reaction occurs at 200oC to 250oC and the catalyst is a mixture of ZnO, CuO and Cr2O3/Al2O3. Copper
metal crystallites are the active species in the catalysts. Copper catalyst is sulfur, halogen, unsaturated
hydrocarbon intolerant and susceptible to thermal sintering
The aim of the study was to investigate the activity of photocatalysts at an ambient temperature. The
object of the study was a series of catalysts in the form of platinum deposited on a titanium dioxide carrier.
Catalytic activity tests were carried out at room temperature. The reaction mixture (5% CO in argon)
flowed through a vertical reactor having a diameter of 45mm with a quartz glass window. The reactor was
filled with distilled water and 0.2 g of the catalyst was placed. The concentration of CO2 was measured using
a FUJI analyzer IR detector. The measurement of the concentration of CO2 was carried out for 120 minutes
of the catalysts exposure to UV radiation (maximum at 362 nm) and immediately followed by the 60 minute
step without UV radiation.
Tested platinum catalysts showed high activity. Catalytic activity was dependent on the concentration of
the metallic phase and the temperature of reduction. Catalysts with a higher content of the metal phase
showed improved activity. The highest catalytic activity was achieved after reduction at 500°C.

Abstract:
Wastewater treatment is a technological process consisting in removing pollution from wasterwater and
sludge, and substances dissolved in them, colloids (e.g. emulsions) and suspensions. During the industrial or
municipal waste treatment by physical and chemical methods, in many cases it will encounter on pollution in
the form of an emulsion.
In the environment emulsions are present mostly in following states: “oil-in-water” and “water-in-oil”.
Nowadays emulsions are widely used in the various branches of the industry. The fundamental place they
found in cosmetical, pharmaceutical or transport sector. The majority of the mentioned industrial emulsions
are considered to be “oil-in-water” type. Moreover emulsions are applied in the processes of the
environmental protection, precisely within utilization of the industrial and municipal sewage treatment. The
thermodynamic and electrokinetic processes are taking inside, directly affect the balance of the system and
they often cause instability – demulsibility. Demulsibility process of emulsion can be the result three
extending parallel or sequentially processes: flocculation, creaming and coalescence.
One of the main processes used for mechanical wastewater treatment in industrial and municipal
wastewater is flotation. This process foresees flotation of oil droplets that are present in the dispersed phase
of emulsion as a result of their separation from the aqueous phase of emulsion. Thus flotation is defined
as a process of phases division, in particular separation of the solid phase from the liquid phase or liquid
phase from the liquid phase. Usually process of flotation can be intensified due to applying of additional
affecting factors e.g. air bubbles. Then this process is called dissolved air flotation (DAF). This technology
used micro-bubbles of 40 to 120µm, which in view of the small particle size dispersions (from 3 to 15µm)
is a high probability of contact of the dispersed phase (oil) with an air bubble.
It used measuring equipment that is applied for one of the widespread spectrophotometric methods –
turbidimetry, because it gives opportunity to define oil concentration after process of the emulsion
demulsification - an optical analyzer Turbiscan.
The purpose of this research work focused on assessment and compartment of the effectiveness of
tradition demulsification and demulsification stimulated by air microbubbles (Dissolved Air Flotation).
Influence of various surfactant concentrations on demulsifying process was also investigated in the frame of

Abstract:
The metal complexes with ligands with a potential pharmacological application, are little known and
they are interesting objects to investigated. The results of previous studies suggest that desirability of deeper
knowledge of these compounds, with particular emphasis on structures and uses. This paper refers synthesis
and proprieties of novel compounds of metal transition with lactic (LA), nicotinic (NIC) and p-aminobenzoic
acid (PABA). All these ligands are used mainly in pharmacology and also in the cosmetic and food industry.
Lactic acid improves liver, kidney and intestinal villi action. It prevents gastroenterolic diseases, and
stimulates the organism acid-base system. PABA (vitamin B10) stimulates bacterial flora to folic acid
production. It prevents also impaired fertility and provides a healthy looking skin and hair by concentrating
in the cells and protects against harmful UV rays. Nicotinic acid dilates the blood vessels of the skin, heart
and brain. It has an anti-atherosclerotic, bile and blood pressure level lowering. It stimulates the secretion of
gastric juice and enhances the motility of the gastrointestinal tract.
For the synthetized compound was made different physic-chemical investigations. Conductivity
measurement in methanol (MeOH), dimethyl sulfoxide (DMSO) and dimethylformamide (DMF) solution
permitted to qualify the type of the electrolyte, based on the literature data. Thermal decompositions of
obtained compounds was examined in the dynamic oxygen atmosphere using the TG and DTG technique.
The analysis of absorption spectra in the infra-red radiation gave the information about type of the metalligand binding and presence of water in complexes. The X-Ray diffraction patterns defined the degree of the
crystallinity and isotype of them.

Abstract:
Non-steroidal anti-inflammatory drugs (NSAIDs) due to their anti-inflammatory, analgesic and
antipyretic properties belongs to the most widely used medicines in the world. O-hydroxybenzoic acid
(salicylic acid, SA) is the first synthetically obtained steroidal anti-inflammatory drug (NSAID). It is used in
the pharmaceutical industry, drug and cosmetic preparations (ointments, creams and gels) for skin care.
Since SA had been the first time synthesized, researches for new anti-inflammatory drugs but with higher
therapeutic activity have been carried out. Many NSAIDs belonging to various chemical groups, with
different anti-inflammatory, analgesic and antipyretic activity, were developed. Active substances
in NSAIDs includes also o-acetoxybenzoic acid (acetylsalicylic acid, aspirin, ASA). Acetylsalicylic acid
is applied in curing pain and fever decrease.
Unlimited access to NSAIDs and the possibility to purchase them without a prescription, as well
as access to drugs originated from unknown sources, cause a danger of their uncontrolled use in huge
amounts. Application of these drugs by patients, without the knowledge of their actions and interactions
between them, can result in unwanted side effects. Due to this fact, electrochemical and analytical studies
of NSAIDs are very important and can be useful in estimation of their effect on human body and his health.
Taking into consideration results of electroanalytical studies, electrochemical properties, especially antireductive properties of the studied compounds can be determined. Results of the investigations can be
helpful for the pharmaceutical industry in development of drugs with similar therapeutic action but without
harmful side effects.

Abstract:
For many years the colorimetric methods were the basis for determining the concentration of aluminium
in industrial wastewater. The most commonly used method in this field is based on the ability of aluminium
to form colored complexes with organic compounds such as eriochrome cyanin R or aluminon. Nowadays,
the development of technology has led to the marginalization of the traditional approach and focused on the
analysis with the application of atomic absorption spectrometry AAS. This results from the lower accuracy
of determination of aluminium and greater amount of environmental factors that interfere in the analysis.
The aim of the work is to present problems which occur in the colorimetric method of the determination
of a concentration of aluminium with the use of eriochrome cyanin R as a colour indicator. Additionally, the
influence of pH of chemical reaction on the measured absorbance value and the range of quantification was
described. The attention was drew also to the problems related to the mineralization of sewage sludge using a
mixture of nitric and hydrochloric acids.
The information about the aluminium content in the sewage is the starting point for describing the
possibilities to undergo the process of coagulation in order to minimize the amount of organic residues in
diary production. The process of coagulation of sewage sludge, called conditioning, is used as the first stage
for chemical treatment of liquid waste, in order to its subsequent exploitation. The sewage sludge gives wide
possibilities of its use including application as a manure for growing plants in areas heavily degraded and coincineration with coal.

Abstract:
Nowadays there is a tendency to reduce production costs in all areas of the industry. For this reason it is
important to use computer techniques to simulate the most interesting processes. Using them allows to
design elements properties in the manufacturing process and subsequent exploitation. The aim of the
computer support in the shot peening process is the selection and optimization of technological parameters.
This allows to control obtained stress and strain state in the treated elements.
In
this
paper
there

modeled
shot
peening
process
on
aluminum
samples.
Shot peening is type of surface plastic treatment which main goal is to improve treated surface. As a result of
the shot stream impacts compressive stresses are introduced in surface. It increase endurance properties, and
above all the fatigue strength. There will be also beneficial changes in friction coefficient, erosive wear,
cavitation resistance or galling resistance (fretting).
The numerical model was prepared based on surface strengthening process by plastic deformation- shot
peening. The main parameters affecting on the value of the stress created during this treatment are: the
sample distance from the nozzle and the shot velocity and diameter. The analysis were subjected to each of
the above parameters. ANSYS LS- Dyna solver was used to carry out computer modeling of fast and
dynamic phenomenon. Computer simulation allowed to analyze the strain and stress distribution and the
depth of it in function of shot peening process parameters.

Abstract:
This paper describes increase tribological properties of 7075 aluminum alloy by depositing a gradient
coating of high adhesion to the substrate using RF PACVD method.
To eliminate forming of thin Al2O3 layer with relatively poor adhesion to the aluminum substrate,
gradient a-C: H/Ti layers synthesis hybrid plasma chemical RF PACVD reactor equipped with pulsed
magnetron sputtering system was used. Using such configuration enables forming a thick and highly
adherent diamond-like carbon layer on aluminum surface with low coefficient of friction (0,05),
at a substrate temperature below 200ºC. Due to application of Ti magnetron cathode it was possible to
improve the adhesion strength up to 21mN of diamond-like carbon layer to the covered substrate.
Influence of deposition parameters on microhardness profile as well as adhesion and morphology were
determined by nanotest and AFM, respectively. Additionally, influence of ionic volume, bond energy and
chemical affinity of counter body on tribological properties of were determined.

Abstract:
Abrasive machining is one of the most important methods of shaping machine elements. As a result,
should receive the items with high dimensional accuracy, with the expected parameters describing the state
of the surface layer (SL) [1].
Grinding difficult to machine materials used in the aerospace industry is an issue currently being
examined by various research centers. An excellent example is the analysis of the grinding process, titanium
alloys, as these materials have very poor machinability due to the tendency to of adhesion abrasive materials,
low thermal conductivity, high strength and susceptibility at elevated temperatures, which may adversely
impact on the quality of the surface layer [2 , 3,4]. On its formation influenced by a number of factors, such
as mechanical and thermal phenomenas, as well as the type of cutting fluids used in the grinding wheelobject zone.
There are many methods of controlling the grinding process, among which was selected: measurement
of cutting force components tangential Ft and normal Fn. On the basis of preliminary tests, the impact of
cooling lubricant, fed by MQL (Minimum Quantity Lubrication), on the force values Ft and Fn was
observed.

Abstract:
Penetration of oil-spill-derived emulsions into the aquatic ecosystems has become quite serious problem
and poses extremely high risk to the marine and terrestrial environments due to high level of their toxicity.
Correspondingly, effective and short-time recovery of the mentioned contaminants is a priority point at
issues of the environment safety.
The following researches were conducted to evaluate experimentally kinetics of porous media imbibition
with O/W emulsions. Spontaneous imbibitions is considered to be a fluid transport into porous medium due
to spontaneous suction of a fluid forced by the capillary pressure. The capillary suction is observed
as a result of the wetting of porous medium by the penetrating fluid. The purpose of investigations was to
describe this process and predict by means of various mathematical models commonly used in other
branches of science for the estimation of the rate of occurring processes like the adsorption or efficiency of
chemical reaction. Finally their adequacy was compared with the classical Lucas–Washburn equation. The
peculiarity was to take into consideration and describe the kinetics of the mass changing of the imbibed
emulsion during fixed period of time rather than correlation of a height parameter with time.
The experimental media were oil in water (O/W) emulsions prepared by means of water mixing with
kerosene oil mixing. The dispersed phase concentrations (DPC) were: 1%; 5% and 10% with the surfactant
concentration of 2 %. The porous medium used in model experiments was polypropylene fiber “Polfilter”.
The investigations of kinetics of the porous medium imbibition with O/W emulsions give opportunity to
develop efficient recovery materials that contribute to diminishing of both short and long term negative
consequences of aquatic ecosystems contamination and facilitate preservation of the pollution-sensitive
components of the environment.

THE CRYSTAL STRUCTURES OF EVEN-TOED UNGULATES SERUM ALBUMINS IN
NATIVE FORMS

Abstract:
Serum albumins represent up to 60% of proteins in the blood plasma. Their high concentration, very good
solubility in water and ability to bind a number of small molecules make them a universal carrier. Albumins can
bind fatty acids, hormones, metabolites, drugs and toxins. Their molecular mass is approximately 67kDa.
Mammalian serum albumins are three-domain helical proteins possessing 17 disulfide bridges stabilizing the
structure. Each domain (I - III) consists of two subdomains (A, B) that have different affinity to the ligands.
Presently, among even-toed ungulates’ serum albumins, only the crystal structure of bovine serum albumin
(BSA) is known (PDB ID: 4F5T) [1]. I present new structures of ovine (OSA) (PDB ID: 4LUF) and goat (GSA)
serum albumins. Sequential differences between even-toed ungulates’ albumins are relatively small. The amino
acid sequences of BSA and OSA, as well, as of BSA and GSA are identical in 92%. Identity between OSA and
GSA equals 98.5%. It is interesting, that even small difference between their sequences causes changes in tertiary
structures, which influence on flexibility of the structures and capacity of the binding pockets. The strength of
ligand binding is differentiated for individual even-toed ungulates’ serum albumins.
The investigated albumins possess abilities to crystallize in number of crystallization conditions creating
crystals with different morphology and space groups. Additionally, for BSA, OSA and GSA more than one
crystal form was identified. Known crystallization conditions for one serum albumin can be treated as a hint to
obtain crystals of the other closely related albumins.

Abstract:
Tuberculosis is an infectious lungs’s disease, caused by Mycobacterium tuberculosis, especially active in
poor countries. This disease remains a serious problem, because of increasing resistance of the bacteria to
known medicines. For this reason, searches for new tuberculostatic drugs are undertaken in many
laboratories.
With this goal in mind two structures: N’-(1,3-dithiolane-2-ylidene)-4-nitrobenzohydrazide and its
N-methyl substituted derivative were determined by X-ray crystallography method.
The first compound forms strong NH…O hydrogen bonds between the amide groups in anti
conformation joining parallel molecules into chains running in [010] direction and the molecules are flat. In
the crystals of the N-methylated derivative the amide group has syn conformation and the molecules are
characteristically bent. Also, due to lack of acidic NH group only weak C-H…O and C-H…N
intermolecular hydrogen contacts are observed.

Abstract:
Carum carvi L., caraway, is a plant belonging to Apiaceae family, that is widely distributed and
cultivated mainly for the seeds that are very common spice. Caraway seeds are rich in essential oil and fat
oil. These two oils are the main constituents of oleoresins – plant extracts that consist of volatile and nonvolatile compounds, such as lipids, sterols, waxes, pigments and resins. Oleoresins have many applications in
food, cosmetic, and pharmaceutical products. These substances are very important for the taste, colour,
texture and other important properties like antioxidant and antimicrobial activities. There are two methods
for obtaining oleoresins – classical solvent extraction and supercritical fluid extraction.
Oleoresins were obtained from caraway seeds by solvent extraction in Soxhlet apparatus using hexane,
acetone, and ethanol. The fatty acid composition was determined by the analysis of their methyl esters
obtained by transestrification. The phytosterol content and composition was determined in the form of their
trimetylsilyl ethers obtained by derivatization. All the samples were analyzed by GC-MS method.
Differences in the yield of oleoresins obtained with different solvents were observed. Ethanol was the
most efficient solvent, that yielded 13,3% of oleoresin, while acetone and hexane yielded 12.2% and 9.6%,
respectively. The content and composition of fatty acids and sterols were similar in three oleoresins. The
major constituents of fatty acids were petroselinic, linoleic, and oleic acids. The main sterol compounds
found in oleoresins were β-sitosterol and cycloartenol.

Abstract:
Thiols, such as cysteine, homocysteine and glutathione significantly affect many cellular function.
Alterations in the levels of certain thiols are linked with many diseases, such as the slow growth of children,
hair depigmentation, liver damage, skin lesions, weakness, Alzheimer’s and cardiovascular diseases,
osteoporosis and other maladies. The optical detection of biothiols is an active area of research due to its
simplicity, high sensitivity, fast responses and potential application for imaging in living cells. This type of
detection is usually based on irreversible chemical reaction between the probe molecules and analytes
[1, 2, 3].
Several N-methyl-3-formyl-2-quinolone derivatives (1-3) were synthesized and characterized
by 1H-NMR spectroscopy and CI mass spectrometry. The spectroscopic properties of these dyes were
examined. The behaviors of the obtained compounds at a pH of 7.4 without and in the presence of L-cysteine
were also studied. The kinetic data were modeled using a pseudo-first-order equation.
