Hydrogen desorption and absorption for activated magnesium hydride
… studied to determine the resultant effects on hydrogen desorption and absorption kinetics for potential use as a hydrogen storage material. It is found that the addition of LiBH4 in small molar ratios results in improved kinetics of the same order as those observed for mechanically milled …

Direct 3D and in situ characterization of light metal hydrides for hydrogen storage
… environmental impact have generated interest in hydrogen as a sustainable energy carrier. Developing effective hydrogen storage for automotive applications is a central challenge in realizing a hydrogen energy economy. Light metal hydrides possess high storage capacities, but sluggish hydrogen …

Hydrogenase utilization and regulation in species of methanosarcina
… others can use H2 as an electron carrier via a hydrogen cycling mechanism, which was previously demonstrated for Methanosarcina barkeri. Both uses of H2 require the activity of three different hydrogenase enzymes, however, M. barkeri can also utilize an electron transport system that is …

A Comparative Analysis of the Performance and the Microbial Ecology of Biological Sulphate Reducing Reactor Systems
… the metabolic potential of these microorganisms. Hydrogen-evolving hydrogenase genes were found to be widespread in genomes not capable of sulphate reduction. In contrast, hydrogen-consuming hydrogenases as well as autotrophic gene pathways were common amongst SRB genomes. The ubiquity of …
