Colloidal bimetallic platinum–ruthenium nanoparticles in ordered mesoporous carbon films as highly active electrocatalysts for the hydrogen evolution reaction [PDF]
, 2020 Hydrogen features a very high specific energy density and is therefore a promising candidate for clean fuel from renewable resources. Water electrolysis can convert electrical energy into storable and transportable hydrogen gas.

Hydrogen Evolution by Trichomonas fœtus [PDF]
Nature, 1951 Trichomonas fœtus, a polyflagellated protozoon, is parasitic in the vagina of the cow and causes impaired reproduction. J. Andrews and T. von Brand1 carried out some quantitative studies on glucose consumption by T. fœtus during cultivation, and then also found that a gas, which burned explosively when mixed with air, was produced by the organism when ...

Surface evolution during crystalline silicon film growth by low-temperature hot-wire chemical vapor deposition on silicon substrates [PDF]
, 2006 We investigate the low-temperature growth of crystalline thin silicon films: epitaxial, twinned, and polycrystalline, by hot-wire chemical vapor deposition (HWCVD).

Hydrogen Evolution Catalyzed by Cobaloximes [PDF]
Accounts of Chemical Research, 2009 Natural photosynthesis uses sunlight to drive the conversion of energy-poor molecules (H(2)O, CO(2)) to energy-rich ones (O(2), (CH(2)O)(n)). Scientists are working hard to develop efficient artificial photosynthetic systems toward the "Holy Grail" of solar-driven water splitting.

Reduced complexity models for water management and anode purge scheduling in DEA operation of PEMFCs [PDF]
, 2010 In this work, the dynamic behavior of Fuel Cell operation under Dead-Ended Anode conditions is shown. A DEA can be fed with dry hydrogen, since water crossing through the membrane is sufficient to humidify the fuel.

Hydrogen Spillover in Electrochemical Hydrogen Evolution Reaction
General Chemistry, 2022 The dissociative chemisorption and energetically driven migration of atomic hydrogen on heterogenous electrocatalysts, i.e., hydrogen spillovers, which occur during electrochemical turnovers, have been intensively investigated recently on high-performance electrocatalysts for hydrogen evolution reaction.
