Hydrogen - Fuel, Energy, Uses: The most important industrial method for the production of hydrogen is the catalytic steam–hydrocarbon process, in which gaseous or vaporized hydrocarbons are treated with steam at high pressure over a nickel catalyst at 6
The most commonly discussed antiatom-based tests of these theories are searches for antihydrogen-hydrogen spectral differences (tests of CPT (charge-parity-time) invariance) or gravitational differences (tests of the weak equivalence principle). Here we, the ALPHA Collaboration, report a different ...
The second channel transfers much more energy and is absent in simulations. It grows with hydrogen atom incidence energy and exhibits an energy-loss onset equal to the Ge surface bandgap. This leads us to conclude that hydrogen atom collisions at the surface of a semiconductor are capable of ...

Hydrogen bonding is the attractive interaction that occurs between a hydrogen atom bound in a molecule to an electronegative atom such as oxygen or nitrogen and another electronegative atom from a different molecule (intermolecular) or even from the same molecule (intramolecular). ...
A consistent quantum-mechanical description is given of some atomistic properties of hydrogen isotopes in bcc metals, including in particular the energy and wave functions of a hydrogen atom, its preference of the type of interstitial si... Fukai,Yuh - 《Japanese Journal of Applied Physics》 被引...
Single-atom catalysts(SACs) are a new research frontier in electrocatalysissuch as in the hydrogen evolution reaction (HER). Recent theoreticaland experimental studies have demonstrated that certain M–N–C(metal–nitrogen–carbon) based... V Fung,G Hu,Z Wu,... - 《Journal of Physical Chemistr...
Tuning photocatalytic selectivity towards industrially significant yet thermodynamically unfavourable products remains challenging. Here a Ga-N5 atomic site on macroporous inverse-opal-type carbon nitride (CNIO-GaSA) is designed and synthesized for visib
