BELANGSUNGKAWA:
ALLAHYARHAM MUHAMAD
IZZAMIR NABIHAN BIN
A. MAJID
Muhamad Izzamir Nabihan Bin A.
Majid dilahirkan pada 8 Oktober 1992 di
Hospital Besar Kuala Lumpur. Anak kedua
daripada lima orang adik beradik ini
adalah seorang anak yang sentiasa
menanam impian untuk menjadi anak
sulung lelaki yang bekerjaya bagi membantu keluarganya. Hal ini disebabkan
bapanya, En. A. Majid Bin Abd Gaffor
yang kini berumur 55 tahun akan bersara
daripada berkhidmat sebagai anggota
polis tidak lama lagi. Hasrat ini telah
dikhabarkan berulang kali kepada ibunya,
Suria Binti Omar dan adik-beradiknya
yang lain. Beliau menjadi harapan keluarga kerana beliau merupakan anak lelaki
sulung dan bakal menamatkan pengajian
di dalam jurusan Ijazah Sarjana Muda
Kejuruteraan Sumber Mineral di Universiti
Sains Malaysia.
Sejak kecil lagi, beliau berhajat untuk
melanjutkan pelajarannya di Universiti
Sains Malaysia. Hal ini kerana USM adalah
tempat yang akan dilihatnya terlebih
dahulu setelah melalui Jambatan Pulau
Pinang setiap kali keluarganya pulang ke
kampung ayahnya di Gelugor. Perkara ini
diberitahu oleh ibu bapanya sendiri.
Menjadi seorang mahasiswa USM merupakan kebanggaannya dan juga keluarga.
Cita-citanya untuk menjadi seorang
Jurutera Pemprosesan Mineral di Rahman
Hydraulic Tin Sdn. Bhd. iaitu tempat beliau menjalani latihan industri selama 10
minggu (semasa di tahun tiga) juga sering diceritakan kepada sahabat-sahabatnya di universiti. Minatnya begitu mendalam di dalam aktiviti perlombongan
bermula sejak tahun pertama berada di
universiti. Buku ensiklopedia kecil mengenai batuan dan mineral yang disimpan
dalam beg beliau sentiasa dibawanya ke
mana sahaja bagi dijadikan rujukan.
Beliau dikenali sebagai seorang yang
mudah didekati dan disenangi oleh orang
ramai terutamanya pensyarah-pensyarah
dan rakan-rakan di universiti. Sikapnya
yang ramah dan terbuka juga membuatkan semua selesa untuk bergaul dengannya. Di kampus, beliau sangat aktif di
dalam aktiviti kokurikulum, badan persatuan dan juga khidmat masyarakat. Sukan
yang sangat digemarinya ialah ragbi.
Beliau menyertai banyak perlawanan di
peringkat universiti dan juga negeri.
Sukan ini menjadi sukan kegemarannya
setelah beliau memasuki universiti.
Dorongan jurulatih dan rakan-rakan
membuatkan beliau bersemangat untuk
menceburi sukan ini. Beliau telah dilantik
sebagai pengerusi bagi kelab ragbi di universiti. Kejohanan Ragbi 10 Sebelah USM
kali ke 10 merupakan jasa terbesar beliau
dalam usaha mempromosikan sukan
ragbi di universiti dan negara.
Buletin Enjinier, Jun 2015
Perjalanan terakhir Allahyarham Muhamad Izzamir Nabihan
Kebolehannya dalam pengurusan sesuatu
acara atau program membuatkan kejohanan tersebut berjaya dilaksana dengan
jayanya.
Di kampus, beliau merupakan ketua
exco desasiswa yang didiaminya iaitu
Desasiswa Jaya. Sifat kepimpinan yang
dimiliki membuatkan beliau ditawarkan
jawatan tersebut. Pada awal tahun 2015,
beliau pernah melibatkan diri dalam misi
bantuan banjir di Temerloh, Pahang. Hal
ini disebabkan sikapnya suka membantu
orang di dalam kesusahan. Perkara ini
dapat dilihat di dalam aktiviti harian di
kampus. Beliau sedia memberi khidmat
bantuan kepada rakan tanpa mengira
waktu dan sebarang alasan. Sikapnya ini
turut dikhabarkan oleh ibunya ketika
mana beliau berada di rumah. Oleh sebab
itu, beliau mendapat perhatian ramai
dalam kalangan pelajar di universiti.
Sesungguhnya Allah s.w.t. lebih
menyayangi beliau setelah terlibat di
dalam kemalangan ketika mengikuti
lawatan akademik ke Acheh, Indonesia
pada 11 Mac 2015 yang lalu. Kehilangan
beliau amat dirasai oleh keluarga, handai
taulan dan universiti. Semoga roh beliau
dicucuri rahmat dan mendapat pengampunan daripada Allah s.w.t.

TRIZ LEVEL 1 PRACTITIONER
WORKSHOP
25 - 26 April 2015 - Innovation is an
important skill much needed in the new
economy. With competition becoming
increasingly intense, innovation is no
longer a “nice-to-have” skill but a “musthave”. There is a way to learn “INNOVATION” in a systematic approach. The
approach is called TRIZ or Theory of
Inventive Problem Solving. TRIZ is a
Russian methodology discovered about
66 years ago but has remained a wellkept secret. This open-secret has finally
reached you through the MyTRIZ Level
1+ Workshop (© MYTRIZ).
This workshop was organize by School
of Materials & Mineral Resources
Engineering (SMMRE) in collaboration
with the Malaysia TRIZ Innovation
Association (MYTRIZ) and Multimedia &
Development Corporation (MDeC).
The aim of this workshop is to bridge
the gap in understanding complex problem solving from the academia and industries perspectives.
Complex problem
solving is a multifaceted skill that is
required among 21st Century Graduates.
This attribute is also an essential outcome
for accreditation of engineering programmes.
Therefore, learning and
exploring on a systematic inventive problem solving is important in meaningfully
preparing and developing our future engineers.
This workshop was attended by 49 students including undergraduate and post
graduate students; participation not only
comes from SMMRE but also School of
Electrical and Electronic Engineering. A
Certified Trainer for TRIZ Level 1, Dr.
Zuratul Ain Abdul Hamid has conducted
and delivered TRIZ Level 1 syllabus
throughout the two days workshop. The
certification was endorsed and certified
by MDeC and MYTRIZ and recognized
Buletin Enjinier, Jun 2015
TRIZ Level 1 Practitioner Workshop
worldwide as the workshop followed the
TRIZ International syllabus. The workshop is hopeful to initiate the creativity
and provide a systematic inventive problem solving that can be used by the students in any problem or research works.
The success of this workshop will not
be realized without the help of organizing
committee lead by Ms. Nor Ezza Sofiah,
3rd Year Polymer Engineering student.
Their enthusiasm and hard works have
resulted in the smooth and success of the
workshop. It is important SMMRE support
more similar workshop to be organized to
enhance and value add our students in
problem solving skill, communication skill
and also build up their confident level
whenever facing any problem in their
studies.

Abstract
Ni embedded ZnO nanorods were synthesized by two step solution precipitation
method followed by reduction in H2
atmosphere at 500oC for 2 hours. The
XRD analysis shows that the as-synthesized particles were ZnO that well crystallized in hexagonal wurtzite structure.
There is no Ni (or NiO) diffraction peaks
could be found in the XRD analysis.The
SEM image confirmed that the morphology of ZnO nanorods did not change with
Ni loading on its surface. The EDX analysis shows the present of Ni beside Zn and
O elements. The photocatalytic activity in
removal of RhB dye by Ni embedded ZnO
nanorods was greatly enhanced when
using a smaller UV excitation source. The
photodegradation efficiency using UV
light with wavelength of 254 nm almost
completely removed RhB, i.e. 98% within
75 min as compared to 58% when using
UV light with wavelength of 352 nm. It is
worth mentioning that the rate constant
of using 254 nm UV light is 0.048 min-1,
which is four times larger than using 352
nm UV light.
1.0 Introduction
Semiconductor photocatalysts have been
attracting research focus recently because
of its great potential as remedy to solve
environmental problems [1]. These semiconductor photocatalysts could be used to
remove organic pollutants by degrading
them into less harmful byproducts such as
water and carbon dioxide under sunlight
[2]. In addition, their other applications
as environmental remedy are to inactivate
microbial [3]and remove heavy metals
[4].
Amongst the semiconductors, wide band
gap TiO2 (3.2 eV) is the most studied pho-
Buletin Enjinier, Jun 2015
tocatalyst as it has high photochemical
efficiency and stability [5-7].A suitable
alternative to TiO2 is ZnO [8] as it possesses a similar bandgap (3.3 eV), low
cost and non-toxic nature. Studies have
shown that ZnO demonstrated a better
photocatalytic efficiency than TiO2 in
removal of 2-phenylphenol [9], Reactive
blue [10], Rhodamine 6G [11], Acid Red
14 [12] and Acid Red 18 [13] in aqueous
solution.
Many attempts have been made to
improve photocatalytic efficiency of ZnO
photocatalyst in degradation of organic
compounds. One of the approaches is to
modify the surface of ZnO by coupling of
another metal oxide semiconductor to
achieve a higher light adsorption capacity
by shifting the absorbance to visible light
region [14, 15]. Another way of improving
the photodegradation efficiency is by
means of restricting the electron-hole
recombination rate of ZnO. This could be
achieved by embedding metals such as
Au [16] and Ag [17] onto the surface ZnO
particles.
In this work, Ni embedded ZnO nanorods
were prepared by two-step solution precipitation. Since ZnO is capable of absorbing irradiation in UV wavelength attributed to its wide band gap, the effect of UV
excitation sources on the photodegradation efficiency of Ni embedded ZnO
nanorods in removal of RhB dye was studied.
2.0 Experimental
Stacked ZnO nanorods were synthesized
by solution precipitation method as
described in our previous paper [18].
Subsequently, the Ni embedded ZnO
nanorods were synthesized by immersing
the ZnO nanorods into 0.03 M of Ni(NO3)2
aqueous solution. The mixture was stirred
at room temperature for 24 hours to allow
the deposition of nickel particles onto the
surface of ZnO nanorods. The white precipitate was filtered and dried in the oven
for 12 hours at 120oC. The product was
calcined at 500oC for 1 hour and reduced
under hydrogen atmosphere at 500oC for
2 hours.
The photocatalytic study on the Ni
embedded ZnO nanorods in removal of
Rhodamine (RhB) dye was conducted
using different UV excitation sources (254
nm and 352 nm). The photocatalytic
activity of Ni embedded ZnO nanorods
was achieved by irradiating mixture of 20
mg ZnO Ni embedded ZnO nanorods and
30 ml RhB (1x10-5 M) by UV light. Then,
photodegradation of RhB solution was
determined by monitoring the decay of its
553 characteristic absorption peak using
UV-VIS Spectrophotometer (Cary 5).
tion peaks could be indexed to wurtzite
ZnO crystal structure (JCPDS No. 01-0792205) with lattice constant of a = 3.250
nm and c = 5.207 nm, regardless ZnO
particles or Ni embedded ZnO particles.
The diffraction peaks at 31.74o, 34.40º,
36.26º, 47.52º, 56.54º, 62.84º, 66.26º,
67.92º and 68.98º are corresponded to
(100), (002), (101), (102), (110), (103),
(200), (112) and (201) crystal planes of
hexagonal ZnO. Their strong and sharp
features suggest that the samples were
well crystalline. No impurity peaks were
observed for both types of particles. This
result indicates that only a small amount
of Ni particles was deposited onto the surface of ZnO nanorods, which was below
the XRD detection limit.
Figure 1: XRD patterns of ZnO nanorods and
Ni embedded ZnO nanorods.
Figure 2 (a) shows the field emission
scanning electron microscopy (FESEM)
image of as-synthesized ZnO nanorods. It
could be clearly seen that the nanorods
have hexagonal tips. As shown in Figure 2
(b), the morphology of Ni embedded ZnO
nanorods did not change with Ni loading
on its surface. However, as shown in
Figure 2 (c), small particles could be
found on the surface of ZnO nanorods.
These particles were homogeneously distributed on the surface of ZnO nanorods.
The EDX elemental analysis was performed on the Ni embedded ZnO
nanorods. As shown in Figure 3, the
analysis indicates that Ni embedded ZnO
nanorods compose of Zn, O and Ni elements.

Figure 4(a) shows the TEM image of Ni
embedded ZnO nanorods. Very fine Ni
particles with size below 9 nm were
deposited uniformly onto the surface of
ZnO nanorods. The HRTEM image of Ni
embedded ZnO nanorod is shown in
Figure 4 (b). The d spacing of 0.26 nm
and 0.20 nm are corresponded to the
(002) planes in the ZnO crystal lattice and
(111) plane planes of face-centered cubic
(fcc) Ni[19].
The optical band gap of ZnO
nanorods and Ni embedded ZnO
nanorods were investigated using UV-Vis
absorption spectra [20]. The band gap
energy was calculated by extrapolation of
the linear portion of the plot with respect
to hv at α = 0 as shown in Figure 5. The
optical band gap for both ZnO nanorods
and Ni embedded ZnO nanorods is 3.09
eV, indicating that the small amount of Ni
loading was not sufficient to cause red
shift of the absorption edge of Ni embedded ZnO nanorods [21, 22].

3.2 Photocatalytic Study
The effectiveness of Ni embedded ZnO
nanorods to degrade RhB solution using
UV light with different wavelengths was
studied. Figure 6 shows the degradation
of RhB solution over a period of time
using Ni embedded ZnO nanorods as photocatalyst. The RhB solution decolorized
gradually when exposed to UV radiation
for 0 min, 15 min, 30 min, 45 min, 60 min
and 75 min. Figure 6 (a) shows the
absorption spectra of photocatalytically
degraded RhB aqueous solutions in the
presence of Ni embedded ZnO nanorods
under 352 nm of UV light. The
absorbance peak of RhB significantly
decreased to 0.5354 a.u. after 45 min of
UV irritation, then continued down to
0.4030 a.u. upon prolonging the irritation
time to 75 min. Figure 6 (b) shows the
absorption spectra of photocatalytically
degraded RhB aqueous solutions in the
presence of Ni embedded ZnO nanorods
under 254 nm of UV light. The
absorbance peak of RhB significantly
decreased to 0.1512 a.u. after 45 min of
UV irritation, and then down to 0.0200
a.u. upon prolonging the irritation time to
75 min. It could be clearly observed that
the degradation of RhB solution was
faster when using UV light with 254 nm
than UV light with 352 nm wavelength.
As shown in Figure 7 (a), Ni embedded
ZnO nanorods achieved a higher photodegradation efficiency when using UV
light with wavelength of 254 nm (98%) as
compared to 352 nm (58%) after 75 min
irradiation. By plotting the data as ln
(Co/C) of the time-dependent normalized
dye concentrations (which is the ratio
between the initial concentration and the
concentration upon reaction) in Figure 7
(b), linear plots are obtained. This indicates that the decomposition of RhB followed first order kinetic regardless the
optical excitation wavelength. The rate
constants, which determined from the
slopes of Figure 7 (b), is increased almost
four times, i.e. from 0.012 to 0.048
min─1 when the UV wavelength was
changed from 352 nm to 254 nm. This
result indicates that a smaller wavelength
of excitation source (254 nm) supplied
more energetic photons which could pro-

constant was increased from 0.012 min−1
to 0.048 min−1 by changing UV excitation
source from 352 nm to 254 nm. The more
energetic photons from the 254 nm UV
source generated more charge carriers
that were needed for the formation of
free radicals. As a result, the RhB dye
degraded faster when 254 nm excitation
source was used in this study.

4.0 Conclusions
Ni embedded ZnO nanorods were successfully synthesized via two step solution
precipitation, followed by reduction in H2
atmosphere at 500oC for 2 hours. The Ni
particles (<9 nm) were deposited uniformly onto the surface of ZnO nanorods,
without changing the morphology and
hexagonal wurtzite crystal structure of
ZnO. The EDX analysis shows the present
of Ni beside Zn and O elements. The photocatalytic activity in removal of RhB dye
by Ni embedded ZnO nanorods was
greatly enhanced when using a smaller
UV excitation source. It is noted that the
photodegradation efficiency after 75 min
was improved from 58% to 98%, and rate

Abstract
A traditional pour point depressant (PPD) of acrylate polymer is in solid
form at room temperature. The costing
for preheating is a prerequisite to be considered for its utilization in a crude oil
industry. The PPD was improvised as an
emulsion system in order to increase its
flow ability. Evaluation of the emulsion
system has been elucidated and its pour
point depressant performance has also
been studied. The emulsified product
could flow as low as -20oC. The viscosity
of emulsified product is much lower than
traditional PPD, which is about 16 CP. The
particle size of the sample becomes
increased by freeze thawed activities, but
does not affect the stability of the emulsion. The zeta potential is about -43 MV
showing that the emulsion is in the stable
range. The pour point performance of
emulsified product is better compared to
traditional PPD. The increasing trends of
performance by increasing the injection
showing that the polymer content is the
most influenced factor that increased
pour point performance of emulsified
product.

1.0 Introduction
A traditional pour point depressant of
acrylate polymer (Trade name: PD90) has
higher polymer-solvent interaction and
low glass transition temperature. It will
cause the PD90 to solidify at room temperature. To resolve this problem, emulsion technique was used to create emulsified PD90 to form fine droplets in a mixture. The emulsion has two different
phases in which the water-based will form
a continuous phase to act as a carrier for
the oil polymer-based hence give a better
flow ability to PD90[1]. However, the
knowledge on the emulsion state of the
acrylate polymer after being emulsified is
still scarce in the literature. Hence, the
present study aims to investigate emul-

sion behavior such as freezing point, viscosity at room temperature, particle size
and zeta potential of the emulsified products and to evaluate its performance as
pour point depressants towards synthetic
crude oil/paraffin wax solution after being
emulsified.
2.0 Methodology
PD90, emulsifier (MWV) and Solvesso 150
were supplied by ACME Chemicals
(Malaysia) Sdn. Bhd. Xylene and ethylene
glycol were purchased from Merck Sdn.
Bhd. PD90 consist of 40 to 60 wt. % of
acrylic polymer in xylene. Emulsified PD90
was prepared by mixing all chemical at 50
oC and stirred at 500 rpm for 1 hour. The
mixture was sonicated at 70 Hz until the
mixture reach 60oC. The thermal properties were determined by using Mettler
Toledo

Calorimetry (DSC), United States system
3.0 Results and Discussion
Flow ability of emulsified PD90
Solvent based PD90 has a low melting
point of around 45oC which will make it
solidify at room temperature. To utilize
this chemical additive in crude oil’s well,
preheating is required to make sure that
this material is pump able. The introduction of an emulsion system to PD90 would
produce a flow able material at room temperature so that the preheating cost
would be discarded. Figure 1 shows the
DSC curve for the solvent based PD90
and emulsified PD90. From the figure, it
shows that the emulsified PD90 has the
melting point of -20oC while solvent based
PD90 is 45oC. This is due to the emulsion
state that allowing the water-based to act
as a medium without forming any direct
interaction between the polymer. In the
system, polymer would be encapsulating

apparatus with nitrogen as purge gas.
Starting from -60oC, each sample below
10 mg was first heated until reaching 120
oC , held isothermally and then cooled to
-60oC at a pre-defined rate of 5oC
/minute. Viscosity of PD90 after emulsified were measured by using Brookfield
viscometer. Viscometer was loaded with
samples and sheared by using spindle set
no 04. Particle size and zeta potential
were measured on a Malvern Instruments
Nano ZS Zetasizer, using a flow through
cell with a Malvern Instruments MPT-2
Multi Purpose Titrator. Freeze thawed test
was conducted by freezing the samples in
chiller at temperature -10oC for 20 hours.
Then the samples were taken out and
heated in water bath at 50oC for about 4
hours. Samples are then being cooled
down at ambient temperature before
observations had been made. The cycles
has been made until week 4 which equally to 4 cycles. The pour point performance
testing has been made according to
ASTM-D97 method. The method involves
periodically tilting a tube containing sample of crude oil at decreasing temperatures, to find the temperature where
there is no movement of the crude.
by emulsifier to present as small droplet
or particle inside the water-based.
Unlikely, the polymer in solvent based
PD90 had directly coiled with the solvent
so that solution tends to solidified at low
temperature.
Viscosity of emulsified PD90
The viscosity is the most important
parameter that would be considered for
achieving a good flowability of pour point
depressant. After being emulsified, the
emulsion viscosity is only 16 cP at room
temperature as shown in Table 1. The
resulted value of emulsified product is
sufficiently low and suitable for application as the traditional PPD with the range
of <300 cP [2]. Low viscosity would
reduce the cost for pumping during appliTable 1: The viscosity of pour point

cation. The viscosity of the solvent based
PD90 was not able to be measured as it
solidify at room temperature.
Particle size and zeta potential of
emulsified PD90
Particle size is the most important parameter that indicates the stability of an
emulsion [3]. As an emulsion system is
being introduced for this PD90, it has a
tendency to break and the solution
becomes separated at elevated temperature. In considering that factor, freeze
thaw test has been conducted for emulsified product. Figure 2 below shows the
trend of particle size for the sample after
being freeze-thawed for 4 cycles within
20 days. The particle size increases by the
number of freeze-thaw cycles applied to
the samples. However, this trend would
not affect the stability of the emulsion as
there is no separation observed during
the test as shown in Figure 3 below. In
order to confirm the stability of the emulsion, zeta potential of emulsified PD90 is
also determined. The zeta potential value
of emulsified PD90 is about -43 mV. For
such a situation the colloid will be more
stable, the further away it is formulated
from the isoelectric point. The value is in
the range (±40 to ±60 mV) for good stability of emulsion [4]. The electrostatic
repulsion of the particles become main
contributor that will lead to a stable dispersion. The stable emulsion would make
improve storage capability.
Applied test, ASTM D97
A pour point depressant performance test
was conducted to study the emulsified
PD90 response or performance towards
synthetic crude oil after being emulsified.
From Figure 3, emulsified PD90 showing
excellent pour point reduction as compared to solvent based PD90 conducted
at 50oC. This is due to ability of emulsified
PD90 to flow at low temperature as compared to solvent based PD90. The flow
ability of emulsified PD90 provides higher
energy so that it could efficiently propagate in order to inhibit the crystallization
growth of paraffin wax. Furthermore,
micron size of polymer producing from
emulsified product could provide higher
surface area so that the interaction
between polymer and paraffin wax would
be higher. Increase of additive dosage
could also increase the pour point reduction of paraffin wax. This is attributed to
high active content of the polymer which
efficiently inhibits the formation of crystallization growth of wax.

of polymer increased.
4.0 Conclusion
Emulsion behavior such as freezing point,
viscosity at room temperature, particle
size and zeta potential of the emulsified
products has been studied. Emulsified
PD90 could flow at room temperature
while solvent based PD90 become solidified. Emulsified PD90 could flow at colder
temperature as the freezing point of the
solvent is around -20oC. It would ensure
that emulsified PD90 could be stored in a
cold environment as well. The viscosity of
emulsified PD90 at room temperature
was much lower than traditional PPD
results of an ease handling and storage.
The particle size trends have been evaluated after the emulsified PD90 undergo
freeze thawed testing. The trend shows
the increment but do not affect the stability of emulsion. The zeta potential data
had confirmed the stability of the emulsion. The good stability of emulsified
PD90 would allow them to store at any
condition without any separation. The

1.0 Introduction
The mountains above Idaho Springs and
the nearby communities of Black Hawk,
Central City and Georgetown show the
abandoned mine openings and remnants
of a romantic past: the "Rush to the
Rockies" and feverish mining for silver
and gold. The Edgar mine, the Colorado
School of Mines (CSM) Experimental
Mine, is a contemporary to that era. In
the 1870s, it produced high-grade silver,
gold, lead and copper. Today, as an
underground laboratory for future engineers, it produces valuable experience for
those who are being trained to find,
develop, and process the world's natural
resources.The Edgar mine is located in
Idaho Springs, approximately 40 miles
west of Denver, Colorado, U.S.A. It can be
reached by Interstate 70 or U.S. 6.
The CSM Mining Engineering Department
is proud of the Edgar Experimental Mine
and the purposes it serves: educational
14
tours for the public and school groups;
cooperation with industry, state, and federal organizations in research; and training of the manpower needed to maintain
the nation's leadership in the field of mineral engineering. Industry is highly supportive of the research and educational
programs at the mine. In fact, most of the
equipment used at the mine is donated
by individual businesses and corporations.
2.0 An Underground Classroom
The Edgar Experimental Mine (Figure 1)
