Research ArticleOpen accessIn the abstractDEEP TRAPS SPECTRA IN UNDOPED GAN FILMS GROWN BY HYDRIDE VAPOR PHASE EPITAXY UNDER VARIOUS CONDITIONSA. Y. Polyakov, N. B. Smirnov, A. V. Govorkov et al.Decreasing the residual donors density and deep traps spectra densities in undoped GaN films grown by Hydride Vapor Phase Epitaxy (HVPE) is very important for promoting the use of such material in high-voltage/high-power rectifiers, radiation detectors. In this study we studied the effects of changing the growth temperature of undoped HVPE GaN films on these properties. The two groups of … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 30 Sep 2014 · 6,901 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcetone Removal and Bioelectricity Generation in Dual Chamber Microbial Fuel CellMostafa Ghasemi, Mostafa Rahimnejad, Ghasem Najafpour et al.Synthetic waste water contain organic compound can be oxidized in an anaerobic conditions in microbial fuel cell while biodegradation of Chemical Oxygen Demand (COD) takes place under anaerobic condition in anode compartment. The microorganisms for biological treatment of the organic matter were obtained from a UASFB bioreactor. In the treatment of waste water, ones COD was removed the current and … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 8,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractEcofriendly and Simplified Synthetic Route for Polysulfone-based Solid-State Alkaline Electrolyte MembraneAphiruk Chaisena, Samroeng Krachodnok, Chutharat Khonkeng, Nittaya PantamasProblem statement: Recently the alkaline system for fuel cell enhance their presence because of possibility of no-precious-metal catalyst and low over potential at cathode reaction. The anion exchange membrane for alkaline membrane fuel cell should be a key technology in order to achieve the practical performance as fuel cells. Alkaline anion exchange membranes of high ionic conductivities are made from … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 15 Aug 2012 · 8,008 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectroosmotic Phenomena in Organic SoilsAfshin Asadi, Bujang B.K. Huat, M. M. Hassim et al.Organic soils or peat represent an accumulation of disintegrated plant remains which have been preserved under condition of incomplete aeration and high water content. In order to develop a fundamental understanding of electroosmotic phenomena in peat, initially microelectrophoresis studies were carried out to conceptualize the electrokinetic phenomena. Then electroosmosis experiments were conducted on rigid cube samples containing 0.0001 M NaCl-water … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,101 accessesView PDFCite
Research ArticleOpen accessIn the abstractCorrosion of Copper Metal in Presence of Binary MixturesMedhat A. Shaker, Hanaa H. Abdel-RahmanThe rates of copper corrosion were determined in presence and in absence of different compositions of water-ethanol, -ethylene glycol, -glycerol, -dimethyl sulfoxide (DMSO) and -dioxane binary mixtures. The rates of corrosion were found to decrease by increasing the concentration of solvents. The percent inhibition range from 10.9 to 78.2% depends on the nature of solvent and its concentration. The calculated … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 8,230 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Study On An Intermediate Temperature Solid Oxide Fuel Cell (IT-SOFT) Fabricated By Dry Pressing MethodA. Rifau, Z. Zainal, D. Mutharasu et al.An intermediate temperature solid oxide fuel cell (IT-SOFC) has been developed by using the dry pressing method. Widely studied materials were used for anode and cathode and SDC based electrolyte was used in this study. The cells were fabricated by dry-pressed at different pressures using a die without any binding material, a known amount of three electrode materials in powder … …American Journal of Applied Sciences, Vol. 3, Issue 9 · 30 Sep 2006 · 6,968 accessesView PDFCite
