Cost reduction and high efficiency are the mayor challenges for sustainable H2 production via proton exchange membrane (PEM) electrolysis. Titanium-based components such as bipolar plates (BPP) have the largest contribution to the capital cost. This work proposes the use of stainless steel BPPs coated with Nb and Ti by magnetron sputtering physical vapor deposition (PVD) and vacuum plasma spray...

unless anaerobic reactor and digesters have been applied worldwide, suitable operation is still challenging. threats of facing with low efficiency operationally, their sensitivity and souring phenomenon are part of typical problems. in this article, the application of electrolysis as an upgrading alternative is investigated for the purpose of controlling its capability on effluent quality promo...

Exhaustive mineralization of pentachlorophenolate ion (PCP) in phosphate buffer was carried out using anodic contact glow discharge electrolysis (CGDE), in which plasma was sustained between the electrolyte and anode. During CGDE, PCP degraded smoothly. The amount of total organic carbon decreased significantly, indicating the eventual conversion of the carbon atoms of benzene nucleus to inorga...

Several types of calorimetric cell designs were used in attempts to measure excess enthalpy during the electrolysis of LiOD/D2O using palladium cathodes. Control experiments were run by using light water in place of D2O or by using platinum cathodes in place of palladium. Initial experiments using thin palladium cathodes of an unknown purity gave no significant differences between the Pd/D2O ce...

An adequate supply of pure water is absolutely essential to human existence. During floods, water is available in adequate quantity, but the quality is often not suitable for drinking or cooking purposes. The goal of the study was to develop an easier, cheaper and faster technique of water purification. Oxygen ions are well known for their high reactivity. An attempt has been made to use oxygen...

CYSTS of the uveal tract have been classified clinically as congenital, parasitic, exudative or degenerative, traumatic implantation, and spontaneous or idiopathic (Duke-Elder, 1940). There is considerable overlap between the last two groups and many cases which one suspects of being traumatic in origin give no history of injury. The tissue forming the cyst in traumatic cases has been implanted...
