The physical and chemical characteristics compared to tritium hydrogen vary slightly; for this reason, it can retain the hydrogen atoms in water. In the tritium atmosphere, one in 1018 of hydrogen is found. Tritium in the atmosphere occurs when the fast neutrons that cosmic rays bring to the ...
And to top this off, the two hydrogen atoms in water contain protons whose magnetic moments can be parallel or antiparallel, giving rise to ortho- and para-water, respectively. The two forms are normally present in a o/p ratio of 3:1. The amount of the rare isotopes of oxygen and ...
As a promising substitute for fossil fuels, hydrogen has emerged as a clean and renewable energy. A key challenge is the efficient production of hydrogen to meet the commercial-scale demand of hydrogen. Water splitting electrolysis is a promising pathway
The presence of three metal atoms reduces the energy barrier of the rate-determining step, giving rise to an effective production of hydrogen from single water molecules. This mechanism differs from dissociative chemisorption of multiple water molecules on aluminium cluster anions, which usually proceeds...
exists combined with other light atoms,e.g.oxygen in water, carbon in methane, or both atoms in cellulose. Asmolecular hydrogenhas to be produced, the relative greenness of the production processes merits analysis; we do this here qualitatively. The analysis is notably based on the 12principles...
Water is one of the most important, yet least understood, liquids in nature. Many anomalous properties of liquid water originate from its well-connected hydrogen bond network1, including unusually efficient vibrational energy redistribution and relaxation2. An accurate description of the ultrafast vibrati...

9. Hydrogen rich water and anti-aging hydrogen rich water are powerful scavengers of reactive oxygen species, also known as "scavengers". Hydrogen rich water contains hydrogen atoms, which can replace biological molecules (cells, genes, and other substances) by...
Hydrogen atoms in azolium ions can be removed easily as protons (e.g. 230 → 232); exchange with deuterium occurs in heavy water. The intermediate zwitterion (e.g. 231) can also be written as a carbene, and in some cases this carbenoid form can be trapped or isolated as a dimer. Sig...
