Microbial electrolysis cell (MEC) is a gripping bio-electrochemical device producing H2 gas from renewable biomass while at the same time treat wastewater.  Through extensive global research efforts in the latest decade, the performance of MECs, including energy efficiency, hydrogen production rate (HPR), and hydrogen recovery have achieved significant breakthroughs. However, employi...

background:  hydrogen has been demonstrated can selectively reduce the hydroxyl, which is the main cause of ionizing radiation-induced damage. amifostine (am) is the only radioprotective drug approved by the u.s. food and drug administration for use in radiotherapy. the purpose of the present study was to investigate the combined radio-protective effect of hydrogen rich water (hrw) and am. mate...

Several bioreactor systems are used for biological treatment of hydrogen sulfide. Among these, airlift bioreactors are promising for the bioconversion of hydrogen sulfide into elemental sulfur. The performance of airlift bioreactors is not adequately understood, particularly when directly fed with hydrogen sulfide gas. The objective of this paper is to investigate the performance of an airlift ...

New energy technologies are needed to limit CO2 emissions and the detrimental effects of global warming. In this article we describe a process which produces a low-carbon gaseous fuel from coal. Synthesis gas from a coal gasifier is shifted to a gas mixture consisting mainly of H2 and CO2. The CO2 is isolated by a physical absorption process, compressed, and transported by pipeline to a deplete...

Subsurface storage of hydrogen, e.g. in depleted oil and gas fields (DOGF), is suggested as a means to overcome imbalances between supply demand the renewable energy sector. However, hydrogen an electron donor for subsurface microbial processes, which may have important implications recovery, injectivity corrosion. Here, we review controls on three major consuming processes subsurface, methanog...

Hydrogen gas can be electrochemically produced in microbial reverse-electrodialysis electrolysis cells (MRECs) using current derived from organic matter and salinity-gradient energy such as river water and seawater solutions. Here, it is shown that ammonium bicarbonate salts, which can be regenerated using low-temperature waste heat, can also produce sufficient voltage for hydrogen gas generati...

A decrease in blood hydrogen ions (H) may allow for the recovery of a muscle, which should allow for greater performance in subsequent activity. The purpose of this study was to determine which of 3 forms of recovery were the most effective after an inning of pitching in baseball. Three different measurements were used to determine which recovery method was most effective; the difference in blo...

The need of establishment biohydrogen purification techniques is due the fact that production will be completely transformed into industrial scale soon or later. For process development to commercially feasible, all involved, including should low cost, practical and efficient; particularly when technically challenging. In any case, carbon dioxide other gaseous impurities are usually evolved dur...
