Hydrogen (H2) will play a key role in the future low-carbon energy society. The industrial production of hydrogen involves chemical reactions and purification steps. Pressure Swing Adsorption (PSA) is versatile process able to produce ultrapure (99.99+%) from various gas mixtures, resulting most widespread technology worldwide. In particular, Polybed PSA system, having more than six beds comple...

Graphene oxide (GO) with its unique two-dimensional structure offers an emerging platform for designing advanced gas separation membranes that allow highly selective transport of hydrogen molecules. Nevertheless, further tuning...

Hydrogen is emerging as a new energy vector outside of its traditional role and gaining more recognition internationally viable fuel route. This review paper offers crisp analysis the most recent developments in hydrogen production techniques using conventional renewable sources, addition to key challenges Hydrogen. Among potential sources for are solar wind. The H2 from derived agricultural or...

Methods for determining changes in higher order structure are valuable to stability studies and purification development, especially those that can be implemented in a high throughput manner. It is often time-consuming to separate or identify different conformations. Recent work on hydrogen-deuterium (HD) exchange shows how ion mobility separation (IMS) can be used to differentiate conformation...

Transitioning to energy-saving and renewable energy sources is impossible without accelerated development of hydrogen technologies. This review summarizes the state-of-the-art recent advances various production processes, including but not limited thermochemical electrolytic processes. Their opportunities limitations, operating conditions, catalysts are discussed. Nowadays, most still produced ...

I describe the characterization, extraction, and purification of a cholesterol:oxygen oxidoreductase (EC 1.1.3.6) from Nocardia sp. This enzyme catalyzes oxidation of cholesterol to z4-choIestenone, with production of hydrogen peroxide. It is very stable, active over a wide pH range, and has a Km of 1.4 X i0 mol/liter. It is highly specific for or 3f3-hydroxycholestanes, and may be applied to t...
