Topic: High energy storage of nickel and cobalt oxides based supercapaictors
Abstract: For energy storage, supercapacitors have attracted great attention recently. Different materials have been proposed
and used for supercapacitors. Due to the different advantages of Nickel and Cobalt for supercapacitor materials, a combination ofboth them attracted more and more attention. In this presentation, I will demonstrate the achievement of Ni-Co oxide and carbon
materials based supercapacitors with very high energy density. Nickel oxide based nanoparticles are synthesized by using various
processes. The energy storage performance of such materials and devices are examined and the reasons for very high energy
storage ability are analysed and discussed. Electrochemical performance, microstructure, morphology and BET surface area arefound strongly related to Ni and Co concentration for the synthesis. Due to the high specific capacitance and the much lower priceof Ni and Co than Ru, a Ni-Co oxide supercapacitor has its unique advantage and may be a very promising candidate for the next
generation of commercial high capacitance supercapacitors.

Full supercpacitor cell prototypes are built and high energy density

is reached, and a small supercapacitor can light a bulb and drive a minifan.

Discover, develop, manufacture, and deploy advanced materials at twice the speed is possible today, at a fraction of the cost.
Advanced materials is trending to fuel emerging multi-billion dollar industries aimed at addressing challenges in manufacturing,clean energy, and national security. Today, what we really need is to spark a renaissance in global research and manufacturing ofadvanced materials and help our manufacturers worldwide to develop the cutting-edge tools they need to comply with the visionof the generation.
This discussion focuses upon the platform mapping for breakthroughs in the next decade in advanced materials' research andtechnologies, speeding ideas from the laboratory and drawing board to the manufacturing floor, scaling-up first-of-a-kind
technologies, and developing the infrastructure and shared facilities to allow entrepreneurs to innovate and compete.
In this synoptic view of materials, we emphasize the crucial, enabling role of materials as a precursor to many major technologicalinnovations forecast for the future. Finally, we discuss briefly the opportunities made available by science and technology forsecuring the future for materials and as part of a broadly based conservation ethic – through developing products with a highinformation content, through improvements in materials processing techniques, through subtle tuning of materials properties,
computer-aided design with built-in recyclability, improved durability through surface protection technologies and a deliberate
drive towards advanced materials with specific functions.
The pace of change in materials technology has broadened and accelerated in recent years. The electronics and computerindustries have gained enormously from developing the use of semiconductor materials. There has been a widening of the scopefor using new composite materials, polymers and ceramics. Research in conventional materials such as steel and aluminum hasenabled their properties to be enhanced to meet new needs and intensifying competition. Advanced materials are often
uncompetitive where considerations of price rather than performance affect the choice of what a product should be made from.

Topic: Porous Ti-based materials for hard tissue implant applications
Abstract: The porous materials based on Ti and its alloys are very attractive for many applications, including hard tissue implants.
Both, surface and total porosity are attractive for medical applications, due to low Young modulus, close in magnitude to that ofhuman bone. The porous Ti- based materials, such as: Ti, Ti-alloys, Ti Void Metal Composites (Ti-VMC) has low Young modulus,
and very good biocompatibility. Into the pores grows a human tissue forming a strong bonding of the implant with bone.
The porous material in the form of void metal composite (foam/scaffold) are made using powder metallurgical process taking two
different powder materials: metallic one (for example titanium) and the second one, which is a space holder material (for examplehydrogen carbonate or polymer particles). The space holder material, which is evaporated at elevated temperature, leaving an
open spaces – pores and thus way a typical porous Ti implants are produced.
In our new concept we found that it is possible to use a saccharose (table sugar crystals) as a space holder particles. The sugar
crystals are easily removed (for example by dissolving in water) from solid Ti + sugar green compact giving a scaffold respective
for sintering. The sintering of the scaffold lead to Ti particles bonding and Ti-VMC strength. In this way a Ti-VMC with more than
70% porosity and pore size of 0.7 mm were made.
In the surface porosity formation an electrochemical etching is useful, especially for the case of Ti-type nanomaterials. In thenanomaterials the large volume of grain boundaries supporting etching process. The grains are easily penetrated by electrolyte
and surface porosity from macro- to micro- can be achieved.

Magnetic Abrasive Finishing of Internal Surface of Aluminum Pipe using Magnetic Machining Jig
Mohd Ridha Bin Muhamad, and Zou Yanhua
Utsunomiya University, Precision Laboratory, Japan
Abstract

R022
Mr. Mohd Ridha
Bin Muhamad

Magnetic abrasive finishing technology has been known very well in finishing of stainless steel
SUS304 pipes to mirror finish standard. However, the applications in softer metal such as aluminum
A2017 were difficult due to soft metal characteristic itself. In 2002, Zou and Shinmura had
developed a new method of magnetic field assisted machining process using magnetic machining jig
for SUS304 pipe [1]. The development has since then expanded in many research. This researchfinds the optimum finishing condition for mirror finish standard in internal surface of aluminum
A2017 pipe. We use a 100% polyester fabric that does not cause scratch on the material and foundthat the optimum pole-pipe gap to be 13mm to achieve the best surface roughness Ra of 0.020μm
after finishing, from surface roughness Ra of 0.195μm before finishing.

Assoc. Prof. Seksak
Asavavisithchai

Open-cell Al foam has outstanding properties which are suitable for functional applications.
However, a major drawback for widespread employment of Al foam is its high relative cost which canbe several times higher than conventional metals. To reduce the cost, a recycled material waste isconstructively used instead of expensive base metal. The present study aims to fabricate economical
open-cell Al foams using AC8A alloy scrap from lathe machines. The Al foams were fabricatedthrough pressure infiltration casting process at which the cellular pattern was made fromcommercial reticulated open-cell polyurethane foams with the pore size of 12 ppi. The compressive
strength and microhardness of scrap-recycled Al foams are higher than those of pure Al foam. The
increase in foam mechanical properties resulted from the change in foam microstructure as theformation of Si hard phase in Al matrix. The strength and microhardness of the foams increase withincreasing scrap contents.

Abstract
This paper presents an alternative statistical signal analysis method to characterise and determine
Young’s modulus property of metallic materials. For this characterisation purpose, we propose analternative method called Integrated Kurtosis-based Algorithm for Z-notch filter(I-kaz™)
and Mesokurtosis Zonal Nonparametric (M-Z-N). Impulsive excitation test has been performed
according to ASTM E1876 on three metallic materials of medium carbon steel S50C, stainless steel
AISI 304 and brass to measure the piezoelectric and acoustic signals. The transient acoustic signal
has been analysed using M-Z-N analysis while I-kaz™ has been used to analyse the impulsive
piezoelectric signal. Correlation expression between Young’s modulus property and the calculated
statistical parameters has been discussed and the accuracy of these two methods has been
identified using cast iron FCD 500 specimen.

Abstract
Taguchi Gen'ichi introduced Mahalanobis-Taguchi System(MTS) which is in combination with theconcepts of quality engineering and Mahalanobis Distance(MD). The MTS is proposed as diagnosis
and forecasting method using multivariate measurement scale with its intention to help policy makeras basis for decision making. This study applies MTS approach in a manufacturing process to reducea set of parameters, at the same time there will be a pattern, which can forecast and identify
important parameters, constructed by MTS method. Through this pattern can minimize unimportant
inspection in process and save unnecessary time and cost. The primary goal to structure ameasuring scale which makes accurate forecasting in multidimensional system. The case study inthis paper reviews the planarity of back-end process in 8-inch silicon wafers on the purpose toconstruct a pattern of reduced set of parameters. In this paper, using thirty-two current variables asreference space and furthermore reducing the variables to seven parameters in order to predict
defective items. As a result, it has still good discriminant accuracy. If validation of the reduced-set
parameters is reliable with its good discriminant accuracy, it means that the company in this casestudy can built defective items warning of the pattern parameters in back-end process because thisapproach of selecting parameters is feasible.

This research aimed to apply the Blown Film Extrusion technique to synthesize the titanium dioxide(TiO2) bio-composite films incorporated on a thin film as a photocatalyst. The biopolymer materials
have great recognition via their renewable and biodegradable characteristic and the green
composite has been a new challenge path to replace traditional polymer composite. In this work,
TiO2/Polybutylene succinate (PBS) bio-composite film was developed to be used as a supporter for
determining the photocatalytic oxidation activity of the TiO2 on the chlorinated volatile organic
compounds degradation. PBS is a synthetic biopolymer which has a reasonable mechanical strength.
The modified-TiO2/PBS bio-composite films were studied to evaluate the degradation ofdichloromethane. In order to improve the distribution of the developed photocatalyst, the TiO2
powders were modified by 0.05% mole of ethyl triethoxysilane (ETES) and stearic acid (SA),respectively. The 10% wt. TiO2/PBS bio-composite films with thickness of 30 µm were prepared byblown film technique. To evaluate the dispersion efficacy, the modified-TiO2/PBS bio-composite
films were characterized by Scanning Electron microscopy (SEM). Photocatalytic degradation ofdichloromethane in gas phase was determined using an annular closed system photoreactor. The
obtained result which was corresponding to the absorption of TiO2/PBS bio composites film wasinvestigated in a range of 300-400 nm via UV/VIS spectrophotometry. The energy band gap of TiO2,
ethyl triethoxysilane-TiO2 and stearic acid-TiO2 bio-composite film was found to be 3.18, 3.21, and3.26 eV, respectively. The SEM shows that the modified-TiO2 with both ETES and SA exhibit uniform
dispersion, while the only TiO2 shows an evidence of agglomeration in the PBS matrix. For
photocatalyst efficiency, the photocatalytic activity of modified-TiO2/PBS bio-composite film
increased comparing to the TiO2/PBS bio-composite film. Moreover, the photocatalytic degradationof dichloromethane by ETES-TiO2/PBS bio-composite film yielded degradation efficiency of 47.0%,
whereas SA-TiO2/PBS bio-composite film yielded the removal efficiency of 41.0% for detention timeat 350 min.

Abstract
The localized wear on grinding wheel edges is a common phenomenon on profile grinding since theabrasive grains are less attached to the bond. The grinding wheel wear depends heavily on theprocess parameters, workpiece and wheel composition, causing changes on the process and profile
deviation behaviors. In order to cope with these uncertainties, many natural and synthetic materials
have been used in different grinding processes. However, the influence of mixed compositions of- 10 -

Macau, 2014
different types of abrasive grains on external cylindrical grinding is not well known. In order toassess this relation, a methodology procedure was developed providing an overview of thecinematic edges behavior on a progressive wheel wear. The methodology procedure is based on the
acoustic emission technology, using a transducer with a 50 μm radius diamond tip. The tip, when incontact with a rotating grinding wheel, enables the evaluation of the cinematic cutting edges. The
abrasive grain density was evaluated for different grinding wheel compositions and specific wear
removal values. Furthermore, these results were compared to the profile deviation observed on thesame tool, allowing the assessment of the influence of different microcrystalline corundum grains on
the overall grinding wheel wear behavior.

Abstract
Using current–voltage (I–V) measurements, the temperature-dependent current transport in
Ag/Zn-polar ZnO Schottky diodes was investigated. Both the series and shunt resistances of thediode were altered at the different temperatures, which were related to the amount of free carriers
and the formation of a vacuum-activated surface conduction path, respectively. The reverse biased
current transport was associated with a thermally assisted tunneling field emission of carriers andthe Poole-Frenkel effect, for higher and lower voltages, respectively. The average interface state
density decreased with increasing temperature, which was due to a result of molecular restructuring
and reordering and/or variation of the ideality factor with temperatures across the Ag/ZnO interface.

Abstract
In this paper an experimental program has been carried out in order to compare compressive
strength fc and elastic static modulus Ec of recycled concrete with ultrasonic waves velocity Vp, toestablish the possibility of employing nondestructive ultrasonic tests to qualify recycled concrete. 9
mix of concrete with different substitution percentage of recycled aggregates instead of natural
ones and 27 cylindrical samples have been made.
At first ultrasonic tests have been carried out on cylindrical samples, later elastic static modulus Ecand compressive strength fc have been experimentally evaluated.
The dynamic elastic modulus Ed has been determined in function of ultrasonic wave velocity Vp;
furthermore the correlations among Ed, Ec, fc e Vp have been determined.
It has been demonstrated that ultrasonic tests are suitable for evaluating different deformative andresisting concrete performances even when variations are small.

Abstract
Silicon oxide thin film was formed using reaction of spin-coated dimethyl-silicone-oil and 5% ozone
gas at low temperature of 300oC. Silicone oil is used for lubrication, insulation, and so on, and it isinexpensive and easy to deal with owing to its stability. FT-IR spectrum of the formed silicon oxide
film was similar to that of the thermally oxidized film, and we hardly observed peaks of Si-CH3 andC-H bonds originated in silicone oil. The Si-OH bonds in the film were observed. The Si-OH bondcauses the degradation of the electric properties of the insulator. In order to remove the Si-OH
bonds, the silicon oxide film was treated with an argon excimer light at room temperature. The
wavelength of the light was 126 nm. The amount of Si-OH bond was drastically reduced by the UV
annealing. The energy of the UV light is high and the value is 9.8 eV. The high energy light may cut
the bond of Si-OH. Therefore, the amount of Si-OH bond could be reduced.

Department of Applied Physics and Electronic Engineering, Japan
Abstract
R034
Assoc. Prof.
Kenji Yoshino

ZnS films are formed by chemical bath deposition using variety zinc sources such as zinc acetate(Zn(CH3COO)2), zinc sulfate (ZnSO4), zinc nitrate (Zn(NO3)2), iodide zinc (ZnI2), zinc chloride(ZnCl2) and zinc acetyl (Zn(acac)2). X-ray diffraction results show all broad spectra of ZnS. It isconsidered that amorphous ZnS can be grown. All samples show high transmittance. It is deduced
that the decrease of transmittance around 3.7 eV is due to the ZnS band gap. Scanning electron
microscopy shows that grain size becomes large with decreasing the instability constants of the zincsources. It is assumed that zinc becomes ionization with decreasing the instability constants. All
samples show a signal of O-H bond from fourier transform infrared spectra. It is assumed that theZn(OH)2 exists in each sample.

Blinking in Photoluminescence of InGaN Devices is Caused by Slow Beating of THz Vibrations of the
Quantum Well

Abstract

R. Micheletto

The photoluminescence from III-V wide band-gap semiconductors as InGaN is characterized by
localized large intensity fluctuations, known as ’blinking’, that, despite decades of research, is not yet
completely understood. In structures where there is a three-dimensional confinement, as for example
semiconductors nano-crystals, the phenomena is supposed to be related to temporary quenching due
to highly efficient non-radiative recombination processes (for example, Auger). Nevertheless, in typical
InGaN devices, the band structure is an infinitely wide quantum well, so the understanding of theblinking phenomenon remains elusive. We present experimental data and a model that suggests thatthe discussed optical fluctuations are a general phenomena caused by the slow beating between THz
thermal vibrations of the Quantum Well. These minuscule displacements are occurring naturally all overthe device, the displacements along the growth direction induce a modulation of the matrix elementsthat drives the optical emission process; this have measurable effect on the device photo-luminescence.
In presence of impurities or gradient of concentration, the vibrations have locally slight frequency
differences on adjacent domains, this give rise to a band of beats, and we observe the lower frequency
tail of this band.

Impact of Sandblasting on Fresnel Lens for Concentrator Photovoltaic
Kensuke Nishioka, Kosei Sato and Yasuyuki Ota
University of Miyazaki, Japan
Abstract
When installing concentrator photovoltaic (CPV) systems in desert areas, we must consider the impactof sandstorms on the Fresnel lens in CPV modules. CPV systems are much more sensitive to sandstorms
than flat-panel PV systems because they can only use the direct beam component of sunlight. In thisstudy, the transmittance of a PMMA substrate after sandblasting was evaluated and the influence ofsandblasting on the output of a CPV system was assessed. The transmittance of PMMA decreased withan increase in the momentum of blown sand. The conversion efficiency of a CPV module wasdetermined by equivalent circuit calculation. The conversion efficiency decreased with increasing
momentum. The coefficient of degradation was 0.17 point per unit momentum.

Abstract
Polycrystalline CuInS2 chalcopyrite thin films were formed on a Mo‒coated glass substrate by annealingof a spray deposited precursor film in a sulfur atmosphere at 600 °C. Partial incorporation of Ga in the
CuInS2 film with a Ga/In ratio of ca. 0.2 to form a Cu(In,Ga)S2 mixed crystal was also prepared.
Photoelectrochemical (PEC) analyses revealed that the Ga incorporation was effective to modulate
electric and semiconductive properties of the chalcopyrite film. As a result, relatively large cathodic
photocurrent responses in PEC analyses as well as high photovoltaic properties of a solar cell based on
the Cu(In,Ga)S2 film were obtained.

Abstract

L. Krishnamurthy

Aluminium silicon carbide particulate composites have wide ranging applications in automobile,
aerospace and military industries because of their attractive properties such as high strength-to weightratio, high wear resistance, high temperature stability etc. From the machining point of view, these are
one of the most difficult-to-machine materials, primarily due to the presence of SiC reinforcements
causing an excessive wear of cutting tools during machining. On the other hand aluminium- graphite
composites are widely used in tribological applications because of their excellent antifriction properties,
wear resistance and antiseizure characteristics. Investigations have been carried out in this work toassess the machinability of aluminium matrix composites containing both SiC and graphite particulates
as reinforcements. Turning experiments have been conducted on Aluminium-Graphite-Silicon Carbide
hybrid composites using Carbide and PCD tool inserts to determine the flank wear. Experiments havebeen carried out based on Central Composite Design approach.

Abstract
Aluminium metal matrix composites due to their excellent properties like high strength to weight ratio
and high wear resistant are becoming new generation of materials useful for various engineering
applications. A continuing problem with these composites is that they are difficult to machine.
Machining of these composites depends on the relative content of the reinforcement and the matrix
material as well as on its response to the machining process. Experimental investigations have been
carried out on the machinability aspects of Aluminium hybrid composites reinforced with Graphite andSilicon Carbide particulates. Experiments have been carried out by Design of Experiments approach.
Mathematical models which correlate the interactive and higher order influences of cutting parameterson the resultant force have been developed.

The present study aims to investigate the influence of Coring glass substrate temperature on the
topography, deposition rate, crystal structure, optical, and electrical properties of ZnS thin films
produced by magnetic radio frequency sputtering method. From plain view SEM micrographs, thepebble structure has shown in all ZnS thin films deposited at various substrate temperatures. Throughhigher substrate temperature, smaller ZnS grains can be obtained in the present study. From XRD
analysis, ZnS thin film exhibits hexagonal Wurtzite structure. When thickness of ZnS thin film arrive
300nm, optical transmission rate can be above 85% regardless of substrate temperature and gets
optical energy barrier of 3.9 eV. From electrical measurement, the variation of resistivity withtemperature exhibits a linear relationship for ZnS thin film.

Abstract
The growth of (0002) orientated polycrystalline undoped and Ga-doped ZnO films by DC sputtering
under Ar is described. The (0002) peak intensity decreases with increasing substrate temperature inboth doped and undoped samples. The average grain sizes are very small. This indicates that ZnO films
with low crystallinity are obtained at high substrate temperatures. It is deduced that surface damage
can be increased by high energy plasmas of neutral Ar particles at high substrate temperatures. The
average surface roughness for both undoped and Ga-doped ZnO films decreases with increasing
substrate temperatures. It is deduced that energies of sputter particles decrease with increasing
substrate temperatures due to collisions with Ar particles. The surface roughness corresponds well tothe structure model.

This work reports on a study of thermal degradation of flax fibres to gain an improved understanding of
the use and limitations of flax fibres as reinforcement for thermoplastic composites manufactured by
the vacuum forming process. The effect of heating on chemical decomposition and thermal stability was
performed, using fourier transform infrared spectrometry (FTIR) and thermogravimetry (TG)techniques. In addition, the characterisation of micro structures of failure surface following tensile
testing of the composites was conducted. The results show that the hemicelluloses decomposition offlax fibres during thermal degradation is a factor to have the detrimental effect on the thermal stabilityof fibres, particularly with low heating rate. The present investigation, A decrease of hemicellulose andpectin content of the fibres, a decrease of consolidation temperature and an increase of heating rateduring the manufacturing of flax fibre thermoplastic composites should improve their mechanicalperformance.

Abstract
Three different catfish oil extraction processes were used to extract oil from catfish viscera: process P1
involved a mixture of ground catfish viscera and water, no heat treatment and centrifugation; process
P2 involved ground catfish viscera (no added water), heat treatment and centrifugation; process P3
involved a mix true of ground catfish viscera and water, heat treatment and centrifugation. Chemicaland physical properties of the resulting of catfish oils were evaluated. The P3 process recovered
significantly higher amounts of crude oil from catfish viscera than the other extraction methods. The P3
oil also contained a higher percent of free fatty acid and peroxide values than P1and P2 oils. Oleic acidin catfish oil was the predominant fatty acid accounting for about 50% of total fatty acids. The apparent
viscosity at -5 and 0 ◦C was significantly higher (P < 0.05) than those at 5, 10, 15, 20, and 30 ◦C.

University of Science and Technology of China
Abstract
Water suppression experiments of EPS and XPS are conducted in Standard Combustion Chamber in
USTC in Hefei. The 20 cm * 20 cm PSs were held against a 600 mm*600 mm vertical gypsum board
fixed by steel frame structures to simulate a building facade. A series of results have been obtained.
When the water spray is not applied, the EPS is easier to melt, drip and pyrolyze than XPS under thesame fire load, but causes less amount of CO than the amount of XPS without any water application.
When the water is applied, neither EPS nor XPS has a trend to drip. The amount of CO caused by EPS or
XPS under water spray is much less than that of non-spray. Also the extinguishment time falls fast once
the PS applied water. In addition, these experimental results demonstrate the feasibility of the designed
rig in studying the fire suppression on vertical PS materials using water spray.

In this work, the electronic structure and dielectric function of chalcopyrite CuInSe2 are presented. The
results are based on the full-potential linearized augmented plane wave (FPLAPW) method using thegeneralized gradient approximation (GGA) plus an onsite Coulomb interaction U of the Cu d states. The
dielectric constant, absorption coefficient and refractive index are explored by means of opticalresponse. The spin-orbit coupling effect is considered for the calculations of electronic structure andoptical properties. We find that the results based on our calculation method have good agreementcompared with experimental and other earlier simulations results.

The tarnish and corrosion resistance of 94Ag-4Zn-Cu-Sn alloys and Ag-5.89Sn alloy compared with
Ag-5.95Cu alloy were investigated. The tarnish results show that the DE* value of Ag-5.95Cu alloy ishigher than those of 94Ag-4Zn-Cu-Sn alloys and Ag-5.89Sn alloy due to the sulfide formations such as
Ag2S, Cu2S and CuS. The DE* value significantly decreases with increasing tin content. This is attributed
to the matrix enrichment of tin which protects the sulfur reaction on surface. From corrosion test results,
94Ag-4Zn-Cu-Sn alloys and Ag-5.89Sn alloy provide the noble shift in the corrosion potentials andpitting potentials but the negative shift in the corrosion current density compared with Ag-5.95Cu alloy.
Corrosion rate of 94Ag-4Zn-Cu-Sn alloys and Ag-5.89Sn alloy decrease markedly compared with
Ag-5.95Cu alloy because it depends on the alloying elements and the microstructural changes. Due tohigh solubility of zinc and tin, the microstructures of tin-rich alloys consist of the higher portion of single
phase and less eutectic structure than that of Ag-5.95Cu alloy.

Mr. Dharmendra

The fabrication of ultra thin silicon nitride (SiNX) layer (< 2 nm) on amorphous silicon (a-Si) in-situ
hot-wire CVD by decomposing ammonia (NH3) gas is reported. Approximately 1.5 nm thin SiNX isformed by nitridation of  40 nm thick a-Si for 10 min at substrate temperature of 250 C. The
amorphous phase of SiNX formed on a-Si and a-Si layer deposited on c-Si wafer is identified by Raman
spectroscopy. The formation of ultra thin SiNX by nitridation of a-Si at 250 C is confirmed by X-ray
photoelectron spectroscopy (XPS) depth profile measurement of SiNX/a-Si structured film. The report
indicates that the HWCVD method can be used for fabricating superlattice structures consisting of ultra
thin SiNX layers (< 2 nm).

Mechanical Properties of Dendritic and Inter-dendritic Regions in As-Cast Medium Carbon Steel
Masoud Al-Gahtani and Rian Dippenaar
University of Wollongong, Australia
Abstract
During solidification of steel, dendrite nucleation and growth leads to the segregation of alloying
elements in the inter-dendritic regions. The dendrite arms are low in carbon while alloying elements
segregate to the inter-dendritic regions. During subsequent hot-rolling, this variation in alloying element
content leads to the formation of regions of high and low solute content, which in turn, leads to theformation of microstructural banding during heat treatment. In the present study, the respective
mechanical properties of these dendritic and inter-dendritic regions were studied in medium carbon
steel in order to investigate the rotation of dendrites during hot rolling.

1, 5 and 10 mM) keeping thiourea concentration constant (20 mM). These films were examined fortheir structural and surface morphologies by X-ray diffraction analysis (XRD) and atomic force
microscopy (AFM). Analysis of results suggests that CdS nanorods grow with cadmium sulphateconcentration of 10 mM. The optical properties were investigated using UV–VIS spectrophotometer.
The values of optical band gaps as-calculated from optical transmission measurements suggests thatfilms have energy band gap in the range of 2.38-2.32eV decreases with increase of cadmium

Hydrogel is one of the most interesting materials for use as wound dressing. In this study,
interpenetrating network (IPN) hydrogels were synthesized by free radical copolymerization of sodium
salt of 2-acrylamido-2-methylpropane sulfonic acid (AMPS) and N-vinylpyrrolidone (NVP), in thepresence of poly(vinyl alcohol) (PVOH). The incorporation of PVOH offered the hydrophilicity to thehydrogel. The polymerization was carried out using N,N’-methylene-bis-acrylamide and4,4’-azo-bis(4-cyanopentanoic acid) as a crosslinker and UV-photoinitiator, respectively. The successfulof polymerization was indicated by gel content which was in the range of 86 – 90%. The structure ofprepared hydrogels was confirmed by Fourier Transform Infrared Spectroscopy. In addition, thehydrogel-water interaction was investigated by mean of water content and water retention.
Manipulation of the AMPS/NVP ratio significantly altered the properties of the hydrogels. As expected,
the interaction of hydrogel and water decreased as increasing of NVP contents due to this monomer
provides more hydrophobic functional groups. In conclusion, it is believed that the prepared
AMPS/NVP/PVOH interpenetrating network hydrogels show the potential for use as temporary wounddressing.

Abstract
Strip profile control during rolling is required to assure the dimensional quality of rolled thin strip is
acceptable for customers. Throughout rolling, the strip profile is controlled by using the advanced
shape control rolling mill, such as the combination of work roll crossing and shifting during
asymmetrical rolling, the one of the valuable methods to control the strip profile quality in rolling
process. In this paper, the influences of cold rolling parameters such as the crossing angle and axial
shifting value of work rolls on the strip profile are analysed. The strip shape control is discussed underboth symmetrical and asymmetrical rolling conditions. The obtained results are appropriate to control
the rolled thin strip profile in practice.

Abstract

TriyonoDue to the local heating of welding, deformation will occur on the welding structure. To mitigate thisdeformation, the method called stretching technology was proposed by previous study. In this method,
plate was stretched to certain pre-strain, kept in this condition and then welded to another sheet. It can
reduce the welding deformation significantly. However, pre-strain will change the properties of joinedmaterials and lead different behavior of welded materials. It will be complicated if dissimilar metals are
welded due to different physical and metallurgical properties. Carbon steel SS400 with the thickness of
3.0 mm and 1.0 mm thick-low nickel stainless steel were welded using resistance spot welding (RSW)
process with constant electrode pressure and weld time of 6 kN and 5 second respectively. During
welding process, low nickel stainless steel was stretched in four different levels pre-strain of 0%, 1%,
1.5% and 2%. Welding current were varied in the range from 3.02 to 4.20 kA. Microstructure
investigations and tensile-shear tests were conducted to evaluate the weldability of RSW joint.
Generally, stretching during welding process decreased the fussion zone area of RSW joint. In the low
welding current, there is no fussion in the interface of stretched plate, but fussion still occured in theinterface of unstretched plate. In all levels of welding current, stretching during welding decreased
fussion zone area and led to decrease tensile-shear load bearing capacity of RSW joint.

Birth asphyxia is a major public health problem in the maternal and child health. It is the cause ofillness, death or disability of a newborn baby. If doctors and staff have awareness to provide the proper
treatments in timely manner, it will help to improve the quality of life of children in the long-term. The
purpose of this research is to predict birth asphyxia occurring using three base classifiers;
Backpropagation Neural Network (BPNN), Support Vector Machines (SVMs), and Decision Tree (DT).
Moreover, the popular ensemble learning, AdaBoost, was also applied with the three base classifiers to
improve their performances. The data used in this research were birth asphyxia data collected from
Chaoprayayomraj Hospital of Thailand during 2006 – 2011. The results showed that DT model gave thebest performance in all evaluation measures. However, AdaBoost with BPNN base classifier(AdaBoostBPNN) model, instead, gave the best improvement with the accuracy of 87.80%. This model
can be used to guide doctors and staff for preparing intensive care in special cases to prevent birthasphyxia occurring and reduce the rate of death and disability of the newborn.

It is known that positron annihilation lifetime spectroscopy (PALS) maintains a strong position among
the matter’s structure research methods. This method is based on the positron lifetime registration
implanted into the test substance. One of the models describing the positron behavior in the given
medium is a model of “traps”. Developed by Brandt, Berko and Walker in the 1960s, this model is still
relevant in the present times. The basis of this model is the system of kinetic equations describing thevarious options of positron annihilation in the medium.
The objective of the current research was to relate these equations with the parameters obtained while
processing the PALS spectrum. In the given article it is presented a program for processing the time
spectrum using the model “traps”, comparative analysis using different ways of processing and somedata on the mentioned analysis respectively.

Abstract
Carbon coils could be synthesized using C 2H2/H2 as source gases and SF6 as an incorporated additive
gas under the thermal chemical vapor deposition system. The 304 stainless steel plates and the 100
and/or 300-sized stainless steel meshes were used as the substrates. The characteristics of thedeposited carbon nanomaterials without the catalyst on the different substrates were investigatedaccording to the injection time of the SF6 flow. In case of the mesh-type stainless steel substrate, thecarbon microcoils could be formed without the Ni catalyst. However the plate-type stainless steel
substrate could not give rise to the formation of the carbon microcoils without the catalyst, regardlessof the injection time of the SF6 flow. The cause for the formation of the carbon microcoils without thecatalyst on the mesh-type substrate was discussed in association with the surface energies for theinteraction between the as-growing carbon elements and the surface of the substrate.

The Equivalence Of Commutativity and Independence

GP Jever, Germany
Abstract
The concept of mutual independence is related to basic topics of science as such and especially torelativity and quantum theory. Under which circumstances can something be treated as being free fromany influence, guidance or control of another? In fact, can something be 'absolutely' independent ofanother or of itself at all? Is the concept of independence reference-frame dependent? While theprobability based concept of independence is solved in a logically consistent way, the relationshipbetween independence and commutativity is still a matter of dispute. This publication will make theproof that commutativity and independence are equivalent.

Abstract
In general, it is well known that the Schrödinger equation is not compatible with special relativity theory
to a necessary extent. Thus far, there are already several trials to formulate versions of the Schrödinger
equation to ensure compatibility with special relativity theory, the Klein-Gordon-equation or the Diracequation are some of these attempts.
Material and Methods.
In this paper, Einstein’s relativistic energy momentum relation is re-analyzed, a normalized relativisticenergy momentum relation is derived. The derived normalized relativistic energy momentum relation
together with the known Schrödinger equation is used as a starting point to establish a wave equationconsistent with special relativity theory.
Results.
In this publication, based on Einstein’s relativistic energy momentum relation, the historical problem of
the “particle-wave-duality” is solved. Furthermore, a special relativity theory consistent wave equation isderived.

We employed the density-functional perturbation theory (DFPT) within the generalized gradientapproximation (GGA), the local density approximation (LDA) and the virtual-crystal approximation (VCA)
to study the effect of composition on the structure, stability, energy gaps, electron effective mass,
dynamic effective charge, optical and acoustical phonon frequencies and static and high dielectric
constants of the rock-salt CaxMg1-xSe and CaxMg1-xTe alloys. The computed equilibrium lattice
constant and bulk modulus show an important deviation from the linear concentration. From the
Voigt-Reuss-Hill approximation, CaxMg1-xSe and CaxMg1-xTe present lower stiffness and lateralexpansion. For Ca content ranging between 0.25 - 0.75, the elastic constants, energy gaps, electron
effective mass and dynamic effective charge are predictions. The elastic constants and computed
phonon dispersion curves indicate that these alloys are mechanically stable.

Macau, 2014
Abstract
This study presents a novel optimization approach for injection molding with multiple performance
characteristics through data mining and analysis to effectively determine the optimal process parametersettings. The quality characteristics of the LED lighting modulus can be categorized into the beam angle
and the luminous intensity. The control factors for the process are mold temperature, melt temperature,
injection velocity, packing pressure and VP switch. The Taguchi method is employed to conduct
signal-to-noise (S/N) ratio optimization. Taguchi orthogonal array experiments are performed, and thenthe experimental data are trained and tested by back-propagation neural networks to create a S/N ratio
predictor. In addition, the S/N ratio predictor is combined with genetic algorithms (GA) to obtain theprocess parameter combination on maximum S/N ratio for both beam angle and luminous intensity. As aresult, the proposed novel optimization approach can create the better process parameter settings
which can not only be more robust and meet the dimension specification, but also enhance the stabilityof injection process.

Abstract
This paper presents an optimization approach to find optimal process parameters of multiple quality
characteristics in plastic injection molding (PIM). Melt temperature, injection velocity, packing pressure,packing time, and cooling time are selected as process parameters in the experiment. Besides, productlength and warpage are chosen as multiple quality characteristics. Taguchi orthogonal array is firstly
conducted in the experiment and the experimental data are employed to calculate the signal-to-noise(S/N) ratio. Analysis of variance (ANOVA) is then used to find the best combination of parametersettings for product length and warpage. In addition, BPNN is used to construct an S/N ratio predictor.
Then, the S/N ratio predictor is associated with GA to obtain the optimal process parameter. Finally, twoconfirmation experiments are taken to exam the effectiveness of proposed approach. Experimental
results show that the proposed optimization approach not only can satisfy the quality characteristics,
but also can improve process stability

Abstract
Application of high strength steel to stiffened girder of cable stayed bridge has the advantage of saving
steel. However, it is generally known that the rotational capacity (ductility) of the high strength steel issmaller than that of conventional steel, and application of high strength steel can cause ductility
problems in bridge. The rotational capacity of Beam-column is a crucial design parameter in stiffened
girder of cable stayed bridge. In this study, high strength steel with yield stress of 690MPa was used.
The rotational capacity of the beam-column with high strength steel was derived based on the
stress-strain curve of high strength steel. The theoretical model was verified through a series ofexperimental results and parametric study.

Abstract
Many compounds with high lipophilic character incorporated into nanostructured lipid carriers (NLC) havebeen reported. However, hydrophilic compounds have not been completely investigated. In this paper, weinvestigated the potential of lipid nanoparticles as carriers for aqueous extract of Spirogyra spp. using hot
high-pressure homogenization method. The aqueous extract of Spirogyra spp. (AS-NLC) showed sphericalmorphology with smooth surface under transmission electron microscope (TEM). The encapsulation
efficiency was 61.23± 6.25%. The crystallization of AS in NLC was investigated by X-ray diffraction. AS wasin an amorphous state in the NLC matrix. The in vitro release experiments of NLC exhibited biphasic releasepattern with burst release at the initial 3 h and prolonged release afterwards.

This study investigated the use of a biodegradable polyoxalate blended with poly(vinyl alcohol) nanofibers
to tailor properties of nanofibers and to control release of Rhodamine B from nanofibers. Nanofibers wereprepared using an electrospinning technique. The morphology and average diameter of electrospun
nanofibers were investigated using scanning electron microscopy. It was found that poly(vinyl alcohol) topolyoxalate ratio had a significant effect on the size of nanofibers (~175-403 nm). An in vitro release study
showed that rate of Rhodamine B release increased with increasing poly(vinyl alcohol)/polyoxalate ratios
yielding rate of release in the range of 0.198-0.469 mg%/min. The mechanism of rhodamine B releasecan be explained by a two-stage process of diffusion and degradation. The results suggested that awater-insoluble polyoxalate could govern the rate of drug release. The ability to tune the release ofchemicals from nanofibers has significant implications for controlled release of drugs.

Abstract
The impact of heat treatment temperature on the electrochemical performance of Fe3O4-activated carbon
nanocomposite electrodes was investigated using constant current charge-discharge and Electrochemical
Impedance Spectroscopy (EIS). An improved capacitive behaviour was observed due to the effect ofenhanced ionic and electronic conductivities of the 4 wt% Fe3O4/AC by thermally heating at 200 oC for 6hours. It was found that the internal resistance of 4 wt% Fe3O4/AC composite electrode calcined at 200 oC
for 6 hours is the smallest (2.97 Ω) in comparison to those untreated (4.36 Ω) composite electrodes. The
ion mobility inside the porous composite electrodes is favourable at 200 oC, accompanying with theenhanced electronic conductivity of oxide electrode as a result of improved crystallinity. The EIS results andanalysis not only have significant impact on the fundamental understanding of the temperature-dependent
structural and electrochemical properties of electrode but also provide the insights on the diffusion
mechanism of the nanocomposite in neutral Na2SO3 electrolyte.

Abstract- 25 -

Macau, 2014
To study the erosion behaviors and mechanism of impeller material FV520B in centrifugal compressor, theerosion experiments with polygonal alumina particles were carried out on the high-speed erosion testing
system. Microstructure of the erosion zone was analyzed by SEM to reveal the erosion mechanism. An
erosion model to calculate the erosion rate of FV520B was developed. The results showed that, FV520B
exhibited the erosion characteristics of typical plastic materials, the highest erosion rate occurred at the
impact angle of 24°, the lowest erosion rate occurred at normal impact angle. The velocity index at the
impact angle 24° and 90° were 3.37 and 3.68, it grew as the impact angle increased. The erosion
mechanism of FV520B was micro-cutting and deformation wear, at low impact angles, the erosion was
dominated by micro-cutting wear, while at high impact angle greater than 60 °, the erosion was dominatedby deformation wear. Also the predictions of the erosion model were in good agreement with the results ofexperiments, indicating that this model can be used to estimate the erosion rate of compressor impeller
under different working conditions.

Building on the success of the many earlier studies on electrospun nanofibers technique which provide a
non woven web to the order of nanometers introducing superior properties such as large surface area,
superior mechanical properties and ease of implementation in many fields of applications, elctrospun
nanofibers became an important issue for many researchers in various fields. Using elctrospun fibers as adrug carrier, is showing a huge promising potential for the future of biomedical application. Our work in thisresearch is focusing on engineering a system to control the drug release profile rate especially for wounddressing. Nanocomposite multilayer fibrous membranes, using electrospinning method, have beendeveloped for drug release in form of sandwich structure of three layers. Inner layer which is kept
Polycaprolactane (PCL) loaded with drug. The two outer layers have been changed with different blend
ratios between Chitosan (Cs) and PCL as follow [0%:100% Cs:PCL, 30%:70% Cs:PCL, 50%:50% Cs:PCL,
70%:30% Cs:PCL]. The results showed that the release rate has been affected dramatically by the outerlayer composition. SEM images showed changing in the morphology due to the different in the compositionof outer layer.

Abstract

V. RanjithabalaElectrospinning process is proved to be one of the finest fabrication techniques to produce nanofibers. This
research deals with the experimental study on the effect of various process parameters of electrospinningtechnique such as voltage, flow rate, distance (nozzle to collector distance) and concentration, on thedevelopment of nanofibers from a new polymer, namely PBAT. Taguchi’s experimental design was
implemented to carry out this research by conducting an L-18 orthogonal array. Taguchi method andAnalysis of Variance (ANOVA) were employed to examine the effect of different process parameterssimultaneously on the fabrication of nanofibers. The fibers were characterized through scanning electron
microscope (SEM) for the measurement of its diameter. The experimental results indicate that all thechosen process parameters had significant influence on the fiber diameter. It was inferred that theconcentration and voltage had a very notable impact on the fiber diameter. Confirmation experimental run
was performed on the identified optimal setting of the process parameters.

Abstract
This study is aimed to evaluate the effect of sugarcane bagasse ash fineness on the properties of
cement-based composites. Three sugarcane bagasse ash contents (10, 20 and 30% by weight of cement)
and three particle sizes of bagasse ash (particles less than 45, 75 and 150 μm) were used as a partial
replacement for cement in mortar specimens with a constant water/cementitious ratio of 0.55. The
pozzolanic strength activity test, compressive strength test and scanning electron microscope observations
were conducted and compared. Test results indicated that the compressive strength decreased with theaddition of sugarcane bagasse ash content increased. Addition of sugarcane bagasse ash to replace cementin cementitious composites could provide hydration and pozzolanic reaction, but it would still keep morerugged and some larger pores observed from the paste surface and resulted in the weaker microstructuresand poorer properties in cementitious composites. In conclusion, the critical usage of sugarcane bagasse
ash is 10 % with 45μm particles.

Abstract
Two types of graphene/MnO2 composites were synthesized by different reaction procedures. R-GO/MnO2
was synthesized as follows: first, nanoneedle MnO2 was formed on the GO sheets using various functionalgroups (GO/MnO2). In the second stage, GO/MnO2 was reduced to graphene/MnO2 (R-GO/MnO2) via thedipping method. rGO/MnO2 was synthesized using a different reaction order: first, graphene oxide was
reduced to graphene and nanoneedle MnO2 was formed on graphene sheets. Characterization indicatedthat the nanoneedle MnO2 structures in the R-GO/MnO2 composite were homogeneously dispersed ongraphene sheets, whereas MnO2 in the rGO/MnO2 composite formed aggregates due to absence offunctional groups. The R-GO/MnO2 electrode exhibited a specific capacitance as high as 327.5 Fg-1 at 10
mVs-1, which was higher than that of the rGO/MnO2 electrode (229.9 Fg-1). It is anticipated that theformation of nanoneedle MnO2 on the GO surface following the reduction procedure could be a promisingfabrication method for supercapacitor electrodes.

Abstract.
Bentonite is a synonymous term of montmorillonite which is a clay mineral consisting of 2 : 1
aluminosilicate layered structure. In this work, a commercial bentonite was used to prepare an intercalation
compound [Ca(2,2′-bipyridine)3]2+ in the interlayer space, by solid-solid reaction,which formation was
confirmed by the expansion of the interlayer space of bentonite from 1.5 to 1.8 nm, by powder X-Ray
Diffraction technique. The intercalation compound [Ca(2,2′- bipyridine)3]2+-bentonite was then used as asensor to assemble a potentiometric electrode. The electrode gave best response to sulfide ion in terms of
Nernstian slope. Precision of measurement, reproducibility and percent recovery were also studied. The
electrode could be used to measure sulfide ion in real water samples and gave satisfactory results.

Abstract
Surface modification of the titanium dioxide by doping and co-doping with nitrogen and iron in order tomake the photocatalyst active under visible light was investigated. Solgel method was adapted for the
preparation of surface modified titanium dioxide, where tetra titanium isopropoxide, ammonium nitrate andferric nitrate were used as precursors while maintaining the dopant concentration and calcination
temperature at 0.75% and 600oC, respectively. The prepared photocatalyst samples were characterized by
XRD, FE-SEM and FTIR in order to study their physical properties. The results from XRD confirmed that all
prepared photocatalyst were of anatase phase. FE-SEM image analysis revealed the formation of fineparticles and the FTIR analysis verified the presence of dopants. The effectivity of photocatalysts wastested by performing a standard batch photocatalytic degradation experiment with methylene blue as amodel pollutant under visible light. The result showed that co-doped photocatalyst (0.75% N, 075%
Fe-TiO2-600) yielded a maximum of 76% methylene blue degraded within three hours of irradiation time.

Walking in Macau
Macau Peninsula was originally an island, but a connecting sandbar gradually turned into a narrow isthmus, thus changing Macau into apeninsula. Land reclamation in the 17th century transformed Macau into a peninsula with generally flat terrain, though numerous steep
hills still mark the original land mass. Alto de Coloane is the highest point in Macau, with an altitude of 170.6 metres (559.7 ft). With adense urban environment, Macau has no arable land, pastures, forest, or woodland.
Walking is the best choice to visit Macau, it is not a big city, here, we advise a route to visiting:
1. From hotel Sofitel Macauat Ponte 16 (The conference venue) to Largo do Senado (Senado Square) (议事亭前地)
transportation:1. By walking (10-20 mintues); 2. take bus 33 (10-20 mintues).

A Brief Introduction of Largo do Senado (Senado Square) (议事亭前地)
It is a paved area in the centre of the former Portuguese colony of Macau, enclosed by the buildings of the Leal Senado, the General Post
Office, and St. Dominic’s Church. The square is paved in the traditional Portuguese pavement. The main road of Macau's historic centre,
Avenida de Almeida Ribeiro passes through the square.

2. From Largo do Senado (Senado Square) (议事亭前地) to St. Dominic's Church (玫瑰圣母堂)
transportation:By walking (5-10 mintues)
From the map we will see that, the St. Dominic's Church is enclosing the Senado Square, taking a walk is more convenient than others.
(A: Senado Square, B: St. Dominic's Church)

A Brief Introduction of St. Dominic's Church (玫瑰圣母堂)
St. Dominic's Church is a late 16th century Baroque-style church that serves within the Cathedral Parish of the Roman Catholic Dioceseof Macau. It is located in the peninsular part of the city at the Largo de São Domingos. This construction was finished in 1587 which is the- 28 -

Macau, 2014
oldest in Macau.
The church was built in a Baroque style and is noted for its mixture of European and local Macanese features in its design. This isdemonstrated in the church's use of Chinese-style roof tiles and doors made of teak. The church's high altar features a statue of theMadonna and Child as the centerpiece and is flanked by wood and ivory-carved statues of several saints.

3. From St. Dominic's Church (玫瑰圣母堂) to Ruins of St. Paul's(大三巴牌坊)
transportation:By walking (5-10 mintues)
A Brief Introduction of St. Paul's
The Ruins of St. Paul's refers to the ruins of a 16th-century complex in Macau including of what was originally St. Paul's College and theCathedral of St. Paul also known as "Mater Dei", a 17th-century Portuguese cathedral dedicated to Saint Paul the Apostle. Today, the ruins
are one of Macau's most famous landmarks. It is listed as one of the 29 sites that form the Historic Centre of Macau, a UNESCO World
Heritage Site.

Enjoyment of Food
During the visiting, you can taste a variously delicious food which are famous and popular. Such as traditional Chinese cuisine, local dishes
Macau, Portuguese, Japanese, Korean and Thai food. However, the most attractive one is Portuguese dishes and also be sure not missing
the native snakes sawdust pudding, Pastel De Nata, Fruity Mix, Water Crab Porridge and so on.
