The Sm0.2Ce0.8O1.9(SDC) was prepared by sol-gel method and the layered composites of SDC with Y0.08Zr0.92O3-δ were prepared by screen printing method. This research aims to study the crystal structure and its conductivity character. XRD measurement equipped with Le Bail refinement shows that SDC is crystallized in cubic structure with space group of Fm3m. The addition of YSZ into SDC does not change its crystal structure. However, the cell parameter of SDC is reduced from 5.434036(2) Å to 5.433(0) Å. At 600 °C, SDC has electronic conductivity that indicates the presence of electrons migration that can promotes short circuit during fuel cell operation. The combination of SDC with YSZ forming a layered composite of SDC-YSZ-SDC could reduce the electronic conductivity, eventhough its ionic conductivity is also become lower than single SDC at the same temperature. ICMSET2014-1-021E Fawad Tariq From: Space and Upper Atmosphere Research Commission, Pakistan Title: Hybrid Nanocomposite Material for EMI Shielding in Spacecrafts Abstract: In this study lightweight carbon fiber and multiwalled carbon nanotubes filled hybrid nanocomposite was fabricated for electromagnetic interference (EMI) shielding in spacecraft. Electrical conductivity was conducted to assess the affect of MWCNT addition on composite. EMI shielding effectiveness (SE) was tested in the frequency range of 1-18 GHz. Comparison of SE was also made with AA6061-T6 sheet. Dispersion of nanotubes in the matrix was examined through microscopy. Results indicated that the conductivity was increased with increasing MWCNTs up to 0.25 wt%. Higher loading level of MWCNTs has resulted in decrease in conductivity due to agglomeration in cured samples. Hybrid nanocomposite exhibited improved SE than AA6061-T6 in 1-8 GHz frequency range. Best SE and electrical conductivity was witnessed in 0.25 wt% MWCNT sample. EMI SE in range of -20 dB to -40 dB can be easily achieved in our developed material. ICMSET2014-3-027E 8 Gulur Siddaramanna Shivashankar From: Siddaganga Institute of Technology, India Title: Synthesis and Characterization of Aluminiun 2219 Reinforced with Boron Carbide and Molybdenum Disulfide Metal Matrix Hybrid Composites Abstract: An attempt has been made to develop and characterize the Al2219 reinforced with Boron carbide (B4C) and Molybdenum disulfide (MoS2) hybrid composites. The hybrid composites were prepared by using stir casting technique. The experimental result evaluates the density, micro hardness test & tensile test. The microstructure shows existence of randomly dispersed reinforcement particles and fine reinforcement particles in prepared hybrid composites. X-Ray powder diffraction (XRD) analysis were conducted this confirms the physical content of constituents present in prepared composites. SEM is used to examine fracture surface of tensile specimens for hybrid composites & this consists of ductile & brittle fracture of mixed mode. The test results revels that, the micro hardness and density is minimum for Al2219 and maximum for Al+3%B4C+5%MoS2. The tensile properties of the material vary according to the percentage of reinforcing material added. ICMSET2014-1-018E Widi Astuti From: Semarang State University, Indonesia Title: Coal Fly Ash as A Dual Site Material for Cr(VI) Adsorption: Comparation Between Single Site and Dual Site Isotherm Models Abstract: The major problem in coal-based thermal power plants is related to solid waste called coal fly ash (CFA). CFA is mainly composed of some oxides including SiO2, Al2O3 having active site and unburned carbon as a mesopore that enables it to act as a dual site adsorbent for heavy metals including Cr(VI). To get different characters of dual site, CFA was treated by sulfuric acid (H2SO4) at different concentrations, temperatures and reaction time. Furthermore, treated CFA were used as an adsorbent to adsorb Cr(VI) in aqueous solutions. Equilibrium data were evaluated by single site and dual site isotherm models. It can be concluded, although unburned carbon contributes on the Cr(VI) adsorption, the existence of unburned carbon decreases the amount of Cr(VI) adsorbed because unburned carbon can plug active sites where dominant adsorption occurs. However, dual site isotherm model yielded excellent fit with equilibrium data. ICMSET2014-1-029E Rika Wulandari From: Gadjah Mada University, Indonesia Title: Adsorption of Remazol Brilliant Blue R (RBBR) by C-4-ethoxy-3-methoxyphenylcalix[4]resorcinarene Triphenylphosphonium Chloride Abstract: The adsorption of Remazol by CEMPCRP was studied as a function of pH, contact time and concentration. All experiments were carried out using the batch method. The initial and final RBBR concentration were determinated using UV-Vis spectrometer at = 592.3 nm. The result showed that the optimum condition of RBBR adsorption were at pH 10, contact time 9 360 min, and concentration of 300 mg/L. This adsorption followed the Lagergren (first pseudo order) and Langmuir isotherm adsorption model. The adsorption capacity was obtained 6.51 x 10-5 mol/L and the mechanism is a chemisorption (G = 28.92 kJ/mol) that occurs in the monolayer. ICMSET2014-1-033E Ngatijo From: Jambi University, Indonesia Title: Quaternary Ammonium Modified Silica for Gold(III) Sorption Abstract: In this research, effect of pH toward adsorption of gold(III) on silica modified with methyl quaternary ammonium (SMQA) has been investigated.Additionally, its application an effect of Cr2O42-on adsorbed [AuCl4]-and effect of pH were carried out and to determine by atomic adsorption spectrometry (AAS). The experimental condition was optimized in batch process to achieve the maximum efficiency. The result showed that optimum pH 5 for adsorption. The gold desorbed increasing before 30 minutes, there were before and after adsorbed gold due at the long distribution axis from transmission electron microscopy (TEM) image. The maximum capacity of SMQA obtained 169.98 mg/g.The R2 values indicate that the Langmuir isotherm fit the the experimental data better than the Freundlich at room temperature. The adsorption gold (III) ion with material SMQA was chemisorption and an effect of Cr2O42-to minimize sorption. Is Fatimah From: Islamic University of Indonesia, Indonesia Title: Environmentally Friendly Catalyst of Zirconium Pillared Saponite for Solvent Free Esterification of Menthol ICMSET2014-1-002 Abstract: In this research zirconium pillared saponite clay (Zr-PILS) was prepared for catalysis application. Pillarization was conducted by zirconium isopropoxide via using sol-gel mechanism and the characterization was performed by X-ray diffraction, gas sorption analysis and surface acidity measurement by pyridine adsorption-FTIR measurement techniques. Result showed that pillaring process to saponite produced pillared saponite with increasing specific surface area, pore volume as well as surface acidity that contributed to enhance catalytic activity in menthol esterification. Reusability test was also showed that Zr-PILS activity is relatively stable. ICMSET2014-1-003E Kun Sri Budiasih From: Yogyakarta State University, Indonesia Title: Development of the Synthesis of Chromium and Molybdenum – Amino acid Complexes: A Green Chemistry Approach Abstract: Some concepts of green chemistry were applied on the Synthesis of Chromium(III) and Mo(V) complexes with amino acids. Three concepts were used in this research were changing to safer solvent, using less energy and appliying a shorter process. The optimum pH of the complex formation of Chromium (III) is 4, whereas for Mo(V) complex, the most stable condition is at pH=1.

The structure of the complexes were predicted by computational model. 10 ICMSET2014-2-007E Jaroslaw Jakubowicz From: Poznan University of Technology, Poland Title: Saccharose as a New Space Holder Material for Porous Titanium Implant Formation Abstract: This paper investigates the properties of Ti scaffolds with a porosity of 73%. In the processing route, a new space holder material was applied - saccharose, commonly known as table sugar. Porous Ti was made by the dissolution of sugar crystals from the Ti-sugar green compact and final sintering of the remaining Ti scaffold. The sintered scaffolds showed uniform pore distribution. The pores had polyhedral shape and their dimensions reached 1 mm. The scaffolds were made and investigated with respect to possible medical applications. After all processing stages, the surface was oxidized and showed average wettability with the lowest wetting angle of 81.5o, which was strongly correlated with the condition of the surface. The chemical etching in an HF solution resulted in a strong wettability improvement. Due to very high porosity, the compression strength (1.48 MPa) and Young’s modulus (33.7 MPa) of the scaffolds were relatively low. ICMSET2014-3-009E Waqas Mahmood From: Beijing Institute of Technology, China Title: Structural, Elastic and Optical Properties of Ag-doped Rutile TiO2 Abstract: The structural, elastic and optical properties of Ag-doped rutile TiO2 are studied using the first principles calculations method. Four different functionals are employed using the ultrasoft pseudopotentials (USPs) on a supercell of size 2a × 2b × 1c. The band gaps of un-doped TiO2 obtained using PBE, RPBE, PW91 and LDA-CA-PZ are 1.861, 1.873, 1.857 and 1.854 eVs respectively. However, after Ag substitution in the supercell, the band gaps are reduced for all of the functionals. After substitution, in the region near to the Fermi level, some new electronic states are observed. The calculated elastic constants show that the structure is mechanically stable. The obtained values of the B, G and elastic constants of un-doped TiO2 are consistent with prior published experimental findings. For Ag-doped supercell, implementing PW91, B and G are 119 and 62 GPa. For the same size of supercell, using LDA-CA-PZ, B and G are 152 and 70 GPa. Besides, the results of the optical properties show that the major absorption peaks for all of the functionals locate away from the visible region. This shows poor absorption of visible light and weak photocatalytic activity of rutile TiO2. 11 ICMSET2014-2-001E Yoshimasa Sugie From: Nagoya University, Japan Title: Synthesis of Magnesium based Layered Hydroxide Salt and its Chemical Heat Storage Properties Abstract: A chemical heat storage method is advantageous in terms long periods of time storage and the high storage density are possible as compared to the direct storage methods. Normally, a reversible single reaction is utilized, then the heat storage temperature is limited. On the other hand, in order to store industrial waste ranging widely in the temperatures, it’s necessary to develop a new material which allows heat storage in a stepwise manner in response to temperature changes. In this study, we have investigated the effect of several experimental conditions on the synthesis of Mg based layered hydroxide by simple aqueous solution derived methods. In addition, the potentials of the multistep chemical heat storage property have been investigated. Eka Sari From: Gadjah Mada University, Indonesia Title: Fungal Growth Model of Phanerochaete Chrysosporium and Multisubstrate Degradation including Effects of Initial Moisture Content (IMC) on The Biological Pretreatment of Water Hyacinth ICMSET2014-1-005E Abstract: A mathematical model was developed to predict the kinetics of Phanerochaete Chrysosporium growth and degradation of multisubstrate on a batch process with limited oxygen conditions, and of the effects of varying the initial Moisture content (IMC). The study was conducted on the pretreatment of Water Hyacinth (WH), to degrade the lignin in order to prepare the WH as a bioethanol feedstock. In this pretreatment, the fungus was inoculated on WH where it grew on the surface of the WH. The fungus consumed three different substrates contained in WH as carbon source, i.e. lignin, cellulose and hemicellulose. Experimental data are used to formulate multi-substrate degradation and fungal growth influenced by the IMC. The formula obtained is used for the development of pretreatment process or scaling up. The mathematical formulation is expected as a proper reference to be applied to biological pretreatment on other lignocellulosic materials by various fungi. The constant of fungal growth (μ) is influenced by the 𝑊 amount of the initial Moisture content (IMC) following the equation 𝑊. 𝑒 (1−𝑊𝑚) with μmax value of 0.68872/week, KSL reached 0.7967 g/g DW and the maximum initial moisture content (W m) is 0.67. Keimei Oh From: Akita Prefectural University, Japan Title: Discovery of New Leads as Inhibitors of Allene Oxide Synthase based on Ozagrel Scaffold ICMSET2014-1-019E Abstract: A series of new imidazole-type allene oxide synthase (AOS, CYP74A) inhibitors were synthesized based on ozagrel scaffold. The inhibitory activity of the compounds against AOS was determined by using purified recombinant protein expressed in E. Coli. Among the nine newly synthesized imidazole derivatives, we found that 6-[4-(2-Imidazol-1-yl-ethyl) phenoxy] hexanoic acid ethyl ester (f) exhibits inhibitory activity against AOS with an IC50 value approximately 78±12 M.

Results showed that nitrogen doping improved the photocatalytic activity of pristine ZnO by extending its spectral response to visible region. Using 2 g/L of N-ZnO, 98% MB with the initial concentration of 10 mg/L could be degraded within 2 h at pH 7 under 11.3 klux of visible light irradiation. After 6th run, it still exhibited appreciable photocatalytic activity with 94% MB degradation, indicating its high reusability though a simple pretreatment was performed.

ICMSET2014-3-005E Alias Mohd Saman From: Kanazawa University, Malaysia Title: Thermal Stress Cleaving of Si-Wafer: Investigation of Fracture Initiation during Laser Beam Irradiation 13 Abstract: This paper investigates the fracture initiation at the vicinity of a micro-groove caused by thermal stress through computational and experimental studies. Fracture initiation time has been determined by analyzing the stress intensity factor. Stress distribution was examined by using a finite element method, and the fracture toughness of the material was determined by using a Vickers indentation technique. The fracture initiation process was verified experimentally by monitoring the acoustic emission signals, while the temperature of the laser spot was also measured using two-color pyrometer. The result shows that stress intensity factor was increased with the increase in micro-groove sizes. Consequently, fracture initiation was attained faster. The simulation results show a good agreement with the experimental results in examining the fracture initiation and recognizing the ideal micro-groove parameters for laser cleaving process. ICMSET2014-3-006E Narongpun Rungcharoen From: Thammasat University, Thailand Title: The Simulation of Laser Cleaning of Magnetic Head with Different Temporal Pulses Abstract: Nowadays, hard disk drives (HDD) technology are being developed continuously in order to increase the capacity, and reduce the size of HDD to meet user requirements. To increase the capacity which is equivalent to increasing read/write ability, the flying clearance must be reduced. Current new HDD models show that the fly height is lower than 0.3 µm. If the height of a particle or contamination is higher than 0.3 µm, the magnetic head will scratch the magnetic disk surface. However the process of cleaning in the HDD industry cannot remove particles with size smaller than 0.3 µm[1]. Therefore laser cleaning is selected first because this method can remove small particles [2]. and it does not damage the magnetic head. This research compares the range of temperature needed for cleaning the magnetic head between two types of heat source’s profile. The technique used is the heat transfer by finite element: FEM[3]. This technique provides an important factor of the laser cleaning method that increases the efficiency of particle removal. It is also a non-destructive method for cleaning the surface of the magnetic head slider. Plenary Speech 3 9:00a.m.-9:50a.m. Prof. Ramesh K.

Particular attention was devoted to the estimation of diffusion coefficient of glycerin in platinum electrodes by the use of electrochemical techniques such as the sweep of the potential. Cyclic voltammograms were recorded at different sweep rates (0.01 and 0.07 V·s-1). Randles-Sevcik equation was taken into consideration and a linear relationship was found between the peak current and the square root of the voltage sweep rate from where the value of diffusion coefficient could be determined. The values of Tafel constants, useful in the understanding of electrochemical reaction kinetics are also reported in the present paper. Juan Carlos Beltrán-Prieto From: Tomas Bata University in Zlín, Czech Republic Title: Mathematical modeling of the drying process of chrome shavings This paper described the mathematical modeling of chrome shavings drying by performing a microscopic AE3004 Abstract: balance for water content to describe the unidimensional transfer of water within the solid at a certain temperature. The deterministic model was solved using Laplace transformation and separation of variables methods in order to determine the average free moisture content at different intervals of time during the drying period. Agreement was observed between both, experimental and modeling data. The effective diffusion coefficient of water molecules during the drying of chrome shavings in a tunnel dryer was determined to be 5.8 x 10-6 m2/h. AE2002 Mohammad Ahsan Habib From: Islamic University of Technology (IUT),Bangladesh Title: Surface roughness optimization in turning operation using Hybrid algorithm of Artificial Bee Colony with RSM Abstract: For cost reduction and quality improvement of machining products, optimum output machining parameters such as material removal rate, tool wear ratio and surface roughness is very essential. Moreover, these output parameters are strongly depends on the precision of the machine tool as well as the input machining parameters. In this paper, a hybrid model of Artificial Bee Colony (ABC), which is motivated by the intelligent behavior of honey bees with Response Surface Methodology (RSM), has been developed for optimizing the surface roughness of stainless steel during turning operation. The predicted optimal value of surface roughness of stainless steel is further confirmed by conducting supplementary experiments.

AE2006 Hossein Vaghefpour From: Islamic Azad University, Abadan, Iran Title: Backtracking Search Algorithm for Designing Robust Machine Layout 15 Abstract: This study discusses the relationship between various parameters of drilling and cutting tools using an analytical model is developed for predicting life and wear of twist drills by a temperature dependent friction law. The model permits the continuous determination of the cutting forces along the cutting lips and chisel edge which can be combined with the dynamics forces of the initial penetration and the chip evacuation forces in drilling. The approach is based on representing the cutting forces along the cutting lips as a series of oblique elements. Similarly, cutting in the chisel region is treated as orthogonal cutting with different speeds depending on the radial location. The chip flow is determined by the assumption that the friction force on the tool face is collinear to the chip flow direction. The contact length between the chip and the tool and the temperature distribution at the tool–chip interface which has an important effect on the tool wear were predicted. The model permits to predict the chip flow direction, the contact length between the chip and the tool and the temperature distribution at the tool–chip interface. Using the thermo-viscoelastic model and the temperature friction law, the tangential forces, friction coefficient and contact length on the cutting element as a function of radius, for different feed rate and cutting speed, are obtained. The proposed model results are compared with experimental results and good agreement is obtained. AE3005 Hong-Cheng Wang From: Nanjing University of Aeronautics and Astromautics, China Title: Formation and Storage of on Demand Water-in-oil Picoliter Droplets Actuated by Microfluidic Pulse Inertia Force Abstract: Droplet generating in an immiscible liquid is the core technology of the droplet based biochemistry analysis. A new method, not based on micro-fluidic chip, is here proposed to produce micro scale aqueous phase droplets in oil phase liquid. The principle of the droplet generator is to actuate a hollow PZT stack by a signal generator and a voltage amplification to provide an enough pulse inertia force for a glass micro-nozzle and aqueous phase liquid inside to eject droplets. The minimum diameter of the produced spherical droplets is below 10 μm, which is below 1 pL. The range of droplets formation frequency is 2 Hz~50 Hz. A fused silica capillary is used to store the produced droplets by a designed low-pressure suction apparatus and the distance between the neighboring droplets is controlled by the low-pressure value. The proposed method in this article may be a promising approach for droplet-based single cell encapsulating and analyzing.

AE2010 Thanakom Soontornchainacksaeng From: King Mongkut’s University of Technology North Bangkok. Thailand Title: Comparing of Heat Model in SIE for Ethanol-Gasoline blend and Using High order Iteration Method for the nonlinear Multi-fuel Combustion Equation 16 Abstract: A quasi-one dimensional engine cycle simulation program was developed to predict the simple heat transfer during combustion stroke in a spark ignition engine of ethanol- gasoline blended fuels. A two-zone heat release model was utilized to model the combustion process inside the combustion cylinder by using high order iteration method (HIM) in combustion equation. The fuel, air and burned gas properties throughout the engine cycle were calculated using variable specific heats. The transient heat flux inside the combustion chamber due to the change in the in-cylinder gas temperature and pressure during combustion was determined using the constant of heat rate from enthalpy heat rate coefficient. The program was written in MATLAB. The results of this paper such as the average heat flux cycles of the burned gas during the combustion and shows the emissions of at during the combustion process by high iteration method. Based on these results, it is concluded that the fundamental thermodynamic properties of the fuel, air, and combustion product species are in agreement with previously published results to within the scatter of those results- typically less than 1% form references 1%. The combustion products calculated by the high iteration methods differ by around 1% from the old methods.

ICMSET2014-3-019E Uttamballi Shivanna Mallik From: Siddaganga Institute of Technology, India Title: Effect of Grain Refinement on Shape Memory Properties of Cu-Al-Mn SMAs Abstract: Cu-12.5 wt.% Al-5 wt.% Mn-(0.05 to 0.2) wt.% B alloys were prepared by ingot metallurgy. The Aluminum and Manganese contents of the alloys were maintained constant, while that of Boron was varied. The alloys were then characterized by subjecting them to compositional analysis, Differential Scanning Caloriemeter and microstructural examination. The shape memory effect and superelasticity of the alloys were determined by bend and tensile tests on the alloy specimens. The investigation reveals that Boron acts as a good grain refiner, resulting in a reduction of about 80% in grain size. The addition of Boron also increases the transformation temperatures by ~ 10oC, while at the same time decreasing the strain recovery by shape memory effect by 4%, and that by superelasticity by ~ 2%. ICMSET2014-3-022E Bennur Chandregowda Suresh From: Siddaganga Institute of Technology, India Title: Thermal Property Evaluation of Chilled Aluminum-Alumina MMC Abstract: Now a day’s composite materials are taking very important role in industrial growth. Composite materials are widely used in Automobiles, aerospace, submarine and also in other major 19 fields, due to their special characteristics like light weight, high strength, stiffness, corrosion resistance. The determination of Coefficient of Thermal Expansion (CTE) of MMCs is important to aid its usage in high temperature environment as in the case of automobile combustion chamber. In these applications the stability of the composites over a long period of operation is a critical design consideration. Present work deals with the thermal property evaluation of the Al alloy / alumina metal matrix composite developed using the Stir Casting with chilling route technique. LM 26 Al alloy is being selected as the matrix material as it is a potential alloy for automotive piston applications. Al alloy / alumina MMCs was cast under end chilling technique by dispersing the reinforcement from 6 to 12 wt% the steps of 3% to study the variation in its thermal properties. At the same time chill material is also changed (Copper and MS) for different composition of MMCs cast to study the thermal behavior variations. After casting the required MMC, test specimens were prepared as per the standards to conduct thermal conductivity (K) tests and coefficient of thermal expansion (CTE) tests. Above tests were repeated for different composites containing different weight % of dispersed cast using different chills.

The effect of hot forming (rolling) with different reduction ratios on the hardness and impact toughness properties will be studied. Correlations between different thermo-mechanical treatment parameters, hardness and impact toughness for different grades of low alloy steels were carried out. Different grades of Low alloy steels were selected for the present study. An extensive study will be carried out to investigate the effect of alloying additions and TMT parameters on the hardness and impact toughness of heat-treated low alloy steels. An understanding of the combined effect of TMT and heat treatment on the mechanical properties of the low alloy steels would help in selecting conditions required to achieve optimum mechanical properties and alloy high strength to weight ratio. The scope of the present work is therefore to study the effects of hot rolling reduction ratios on microstructure and mechanical properties of such alloys. By measuring hardness, impact toughness, strength and ductility resulting from different heat treatment following TMT, it is possible to determine which conditions yielded optimum mechanical properties and high strength to weight ratio. Worasak Rotjanapittayakul From: Thammasat University, Thailand Title: A First Principle Study of the Massive TMR in Magnetic Tunnel Junction using Fe3Al Heusler Alloy Electrodes and MgO Barrier Abstract: The massive tunnel magnetoresistane (TMR) is expected when Fe3Al Heusler alloy are used for magnetic electrodes in magnetic tunnel junction (MTJ). We demonstrate the Fe3Al/MgO/Fe3Al MTJ, which have good lattice matching interfaces. The electronic and transport properties of these system are systematically investigated by first principle calculation. The electronic band structure of Fe3Al Heusler alloy and MgO are represented for discussion spin filtering effect. Besides, the transmission conductance is calculated to study the spin tunneling effect. We found that the massive TMR is clearly achieved at zero-bias condition, and the TMR is decreased when the finite bias are applied. Thus, among ferromagnetic materials, the Fe 3Al Heusler alloy will be good alternative to bcc-Fe based electrodes with MgO barrier for the MTJs beyond. 20 ICMSET2014-3-026E Seksak Asavavisithchai From: Chulalongkorn University, Thailand Title: Effects of Aluminum Addition on Microstructural Characteristics in Modified Coated Nickel-Based Superalloy, GTD-111, by Arc Melting Abstract: The nickel-based superalloys, grade GTD-111, were modified by aluminum addition by the mean of vacuum arc melting process, in order to improve microstructure and oxidation resistance at elevated temperatures. The arc melted GTD-111 specimens were added with aluminum of 1, 2 and 3 wt. %. All specimens were then performed with heat treatment, which consists of solution treatment for 6 h at various temperatures of 1125, 1145, 1165, 1185 and 1205C. After that, all specimens were followed by precipitation aging at 845C for 24 h. Finally, to evaluate the microstructural stability, the long-term heating at temperatures of 900 and 1000C for 400 h were performed to the specimens. It was found that the most proper amount of aluminum addition was 1 wt.%, which provided reheat treated microstructures with high area fractions of -precipitated particles, as well as uniformed distribution of cubic -morphology. The most proper solutioning condition is also found at 1165C for 6 h.

The recovered metals are supported on porous glassy carbon substrate by chemical or electro deposition process. The chemical method involves crushing 21 and grinding of the spent brushes to pass 200 mesh. Magnetic separation removed magnetic susceptible metals such as iron. Nonferrous metals were leached using 3N nitric acid in hot conditions. Hydroxide gel of the dissolved metals generated with 1N ammonium hydroxide. The carbon substrate was multi- impregnated with metals hydroxide 3-4 times. In each time, the loaded carbon was dried. Free metals on the carbon substrate are obtained by reducing the hydroxide with hydrazine hydrate or by thermal reduction using hydrogen gas at 900°C. In the electro deposition process, ground spent brushes were packed in a polyethylene cloth used as anode. The electrolyte is 3M of sulfate salt of the metal of concern. Pulse current cyclic voltmetric technique was applied to control the particle diameter and thickness of the deposited metal. Results revealed that monolayer silver and copper of nanoparticles has been successfully prepared from spent metalized graphite brushes. Electro deposition is more friendly environment procedure and more convenient, less cost and more precise.

ICMSET2014-3-007E Agnieszka Bogusz From: Chemnitz University of Technology, Germany Title: Morphological Transformations of Top Electrodes on YMnO3 caused by Filamentary Resistive Switching in the Oxide Matrix Abstract: Unipolar resistive switching in YMnO3 with large-scale bottom and small-scale top electrodes is analyzed in detail by tracking the morphological transformations of the top electrodes induced by applied writing voltages. Micro-scale digital images are taken after each subsequent quasi-static current-voltage sweep. Current mapping after electrical investigations indicates a shift in the conductivity at the localized areas of the morphologically transformed top electrodes. Those changes are assigned to the heat induced structural and compositional changes within YMnO3 which lead to the formation and rupture of conductive filaments observed as unipolar resistive switching. Presented results underline the importance of Joule heating in the fostering of resistive switching and its adverse impact on the device endurance.

The input image of the system is the “dancer” object image of paper currency Rp. 50.000,- fluorescent by ultraviolet light. The coding was carried out using visual programming language. The feature’s size of the dancer tested object is 114x90 px and the Red-Green-Blue-Hue-Saturation-Intensity (RGBHSI) values were extracted as the input for LVQ. The experimental result shows that the system has an accuracy 100% of detecting 20 real test case data, and 96% of detecting 22 simulated test case data. Title: Numerical Simulation of Solidification Processes of Copper Alloys by Vacuum Continuous Casting ICMSET2014-2-008E Abstract: A numerical simulation method is used to analyse the microstructure evolution of 8-mm-diameter brass (70wt%Cu30wt%Zn) rods during the vacuum continuous casting (VCC) process. The macro- and micro-scale coupling method is adopted to develop a temperature field model and a microstructure prediction model. The effects of casting parameters, including casting speed and pouring temperature, on the shape of the solid-liquid (S/L) interface and solidified microstructure are considered. Simulation results show that the casting speed has a large effect on the shape of the S/L interface and grain morphology. Title: Mathematical Formulation of the Global Coefficients of Transmission and Reflection of Ultrasonic Waves in Bi-Phase Porous Medium ICMSET2014-3-017E Abstract: The study of signals propagation inside porous media is an important field especially in the biomedical research related to compact bones. The purpose of this paper is to determine a mathematical formulation of the global coefficients of transmission and reflection of nondestructive ultrasonic waves in any bi-phase porous medium. Local coefficients of transmission and reflection on the interface of the porous medium will be determined based on a study of boundary conditions. The behavior of different waves inside the porous medium will be developed so that we can derive a new formulation of global coefficients that takes interior phenomena into consideration. Results are found independently of the geometrical and physical characteristics of the medium. Note that this study is based on normal incident ultrasonic wave propagation. Title: Degradation Mechanism of Glass/Polyester Composite Exposure to Acidic and Alkaline Solutions at Room Temperature ICMSET2014-3-008E Abstract: The aim of this work is the study of the degradation mechanism of a glass fiber/unsaturated polyester (UP) composite immersed in acidic (H2SO4) and alkaline (NaOH) solutions like establishing a relation between the chemical and the mechanical behaviors of this material. The gravimetric analyses showed a pseudo fickian behavior for the samples immersed in H2SO4 and mass losses with a pseudo-stage of saturation as from 64 hours of immersion for the samples immersed in NaOH. The Fourier transform infrared analysis (FT-IR) of the UP resin revealed the presence of chemical degradation phenomenon (hydrolysis). Microscopic observations (SEM) confirmed the fibres/matrix interfaces degradation. The effect of these degradations has been reflected one the mechanical properties of the materials. Title: The Influences of Annealing Temperatures on the Properties of HfO2 Thin Film and the Fabrication of SiO2/HfO2 Distributed Bragg Reflector ICMSET2014-3-012 ICMSET2014-3-031 Abstract: In this study, HfO2 thin films were deposited onto the Si substrates by RF magnetron sputtering system. After deposition, the HfO2 thin films were then heated by a furnace thermal annealing process in air and at 400-700oC. The surface morphologies and crystalline characteristics of the HfO2 thin films were investigated by using SEM and XRD patterns. The grain sizes and crystalline phases increased with rising annealing temperature. In addition, the SiO2/HfO2 distributed bragg reflector (DBR) was used for improving the external quantum efficiency of the GaN-based LEDs. The output power of LEDs with 9-pair SiO2/HfO2 DBR and with Ag mirror+6-pair SiO2/HfO2 DBR were increased by approximately 10.6% and 7%, respectively, as compared with the LEDs without SiO2/HfO2 DBR. Title: The Influence of Temperature on the Galvanic Corrosion in Multi-material 28 System in Seawater Abstract: The galvanic corrosion behavior of titanium(TA2)/Cu-Ni alloy(B10)/low alloy steel (921A) multi-material system has been studied using a zero-resistance ammeter (ZRA) in seawater at different temperatures. After the tests, the surface morphologies of the samples were detected by SEM. Results showed galvanic corrosion behavior of TA2/B10/921A fulfill the mixed potential theory, 921A acts as the anode and both TA2 and B10 act as the cathodes. The effect of temperature on the galvanic corrosion is important, the corrosion rate increases with increasing temperature. Title: Network-Wide Time Synchronization based on SDH Link Transmission Abstract: Network-wide time synchronization system is a key technology of electric power industry ICMSET2014-3-034 in recent years. High precision time reference signals transmitted by SDH(Synchronous Digital Hierarchy) network and high precision timing network application realized by PTP(Precious Time Protocol) are being studied at home and abroad. External frequency references are required to rectify the access and transmission delay error of PTP over E1 transmission. Based on the time synchronization demonstration project of electric power communication network and the related experimental data, the influence on transmission timing precision caused by frequency deviation on the SDH transmission link are analyzed. It is demonstrated that the frequency synchronization standard of SDH link is critical to the transmission of time synchronize signals, the networking advises on network-wide time synchronization are proposed to realize the entire network coverage of unified reference time signal.
