The trihydrogen cation (H3+) plays a key role in the interstellar chemistry. Here the authors, using state of the art experiments and computation, identify factors that govern H3+ formation from doubly ionized small organic molecules, offering guidelines for examining alternative sources of H3+ in...
In the phase, the incoming hydrogen molecules dissociate and form OHad... C Oh,KS Hong,SG Lee,... - 《Journal of Physics Condensed Matter》 被引量: 11发表: 2006年 Preparation and microstructure analysis of Fe-doped PbTiO3 ceramic Fe-doped PbTiO 3 (PT) powder and bulk materials were ...
These include its renewable nature, high energy yield, ease of conversion to electricity and CO2-free combustion. Despite being the most abundant element in the universe, comprising approximately 75% of all matter by weight, hydrogen exists in its pure molecular form in only trace amounts. Since...
a versatile toolkit of guanidinium organosulfonate hydrogen-bonded host frameworks that form crystalline inclusion compounds with target molecules in a single-step crystallization, complementing the crystalline sponge method that relies on diffusion of the target into the cages of a metal-organic framework...
< / p & gt; & lt; p & gt; the gaseous mixture is brought into a layer of material in bulk formed by a granulate of a metal which is activated in the form of metal hydrides, which has previously undergone a heat treatment in a hydrogen atmosphere in the production of a micro - ...
Of all the molecular glasses, the quadrupolar glass1–12 formed at low temperatures by dilute mixtures of ortho- and para-hydrogen13–18 is the most fascinating as the underlying physics is quantum mechanical. The homonuclear diatomic hydrogen can exist as one of two possible species, ortho and...

Being the lightest, most mobile atom that exists, hydrogen plays an important role in the chemistry of hydrocarbons, proteins and peptides and most biomolecules. Hydrogen can undergo transfer, exchange and migration processes, having considerable impact
study in chemistry. Water is a chemical compound. Each molecule of water, H2O or HOH, consists of two atoms of hydrogen-bonded to one atom of oxygen. The name water typically refers to theliquid stateof the compound, while the solid phase is known as ice and the gas phase is called ...
