Research ArticleOpen accessIn the abstractPhotoelectrochemical Corrosion of GaN/AlGaN-Based p-n StructuresAlexander Usikov, Heikki Helava, Alexey Nikiforov et al.Direct water photoelectrolysis using III-N materials is a promising way for hydrogen production. GaN/AlGaN based p-n structures were used as working electrodes in a photoelectrochemical process to investigate the material etching (corrosion). The structures were grown on sapphire substrates by chloride Hydride Vapor Phase Epitaxy (HVPE). First, the etching process occurs near vertically via channels associated with defects in the … …American Journal of Applied Sciences, Vol. 13, Issue 7 · 31 Jul 2016 · 7,335 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Development of Ni/Dolomite Catalyst in Simultaneous Biomass Gasification and Reforming in Fluidized BedAnawat Ketcong, Tharapong Vitidsant, Kaoru FujimotoSimultaneous gasification and steam reforming of the biomass on Ni/dolomite catalyst in fluidized bed reactor were studied in the gaseous production in the one stage reactor. Problem statement: The parameters such as temperature, steam flow rate, biomass feed rate, gas flow rate for fluidization, oxygen flow rate and catalyst types were studied to produce the high gaseous products including tar … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,067 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordINCREASING ADSORPTION OF ACTIVATED CARBON FROM PALM OIL SHELL FOR ADSORB H2S FROM BIOGAS PRODUCTION BY IMPREGNATIONWasan Phooratsamee, Kanokorn Hussaro, Sombat Teekasap, Jongjit HirunlabhBiogas is the combustible gas produced through a biological process, known as anaerobic digestion which is the process operated at low-temperature and without air. Biogas consists of 55-80% CH4, 20-45% CO2 with trace amount of H2S and other impurities. Common H2S removal technologies from biogas fall into one of adsorption on a solid such as iron oxide based materials, activated … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 16 Aug 2014 · 7,670 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordFeatures Study on Target Fragmentation in the Collisions Of 24Mg and 28Si with Emulsion Nuclei at 3.7A GeVA. Abd EL-DaiemProblem statement: The process of nuclear fragmentation in interactions of 3.7A GeV 24Mg and 28Si nuclei with the different target nuclei in a nuclear emulsion have been investigated. Approach: The probability of interactions without any projectile fragment with charge Z≥2 is zero for hydrogen target, but increases by increasing the mass of the target. Results: The disruption of a projectile … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 7,670 accessesView PDF Cite
