The Solution of Hydrogen in LaNi5 at Low Hydrogen Concentrations.

More affordable electrolytic LaNi5-type hydrogen storage powders.

Compounding between NiO and La(2)O(3) protects the latter from water and molten salt attack, and ensures successful direct electrolytic conversion of the oxide precursors, in the solid state, to more affordable LaNi(5)-type hydrogen storage materials.

Adsorption of Hydrogen Sulfide at low temperature

From an ecological perspective is biogas an important source of energy. It is produced from fermentation of organic material, e.g. household waste and wastewater sludge. The composition of the gas depends on the raw material and varies between 65-85% methane, 15-35% carbon dioxide and small amounts of ammonia and hydrogen sulfide. To use the biogas it is important to purify it from hydrogen sul...

The inactivation of bacillus subtilis spores at low concentrations of hydrogen peroxide vapour

Hydrogen ions kill brain at concentrations reached in ischemia.

Elevation of brain glucose before the onset of nearly complete ischemia leads to increased lactic acid within brain. When excessive, such acidosis may be a necessary factor for converting selective neuronal loss to brain infarction from nearly complete ischemia. To examine the potential neurotoxicity of excessive lactic acid concentrations, we microinjected (0.5 microliter/min) 150 mM sodium la...
