WASHINGTON, Aug. 15 (Xinhua) -- NASA's spacecraft New Horizons has found new evidence of a "wall" of hydrogen at the edge of the solar system, encircling all the planets and objects orbiting the Sun. The "wall" is actually a vast amount of trapped hydrogen atoms caught up in the sol...

5. This effect not only accounts for many phenomena observed in hydrogenation/hydrogenolysis processes6,7, but also makes it possible to decouple the catalytic functions between H2dissociation (to form active H atoms) and subsequent hydrogenation with these atomic H species, rendering the control of...
the hydrogen concentration exceeded 1% (Fig.3c–f), its further increase did not generate observable color and brightness variations, and the pattern looked whiter. This outcome can be understood by the saturation of hydrogen atoms in Pd. In the saturation state, the “H2” pattern became white...
Even a century ago the existence of "nascent" atomic hydrogen in solutions was regarded as a Gedanken artifact of romanticism [ 1 ]. Nevertheless, according to the "nascent" hydrogen hypothesis, zinc reacts with hydrochloric acid, first producing hydrogen atoms (which are radicals). Similarly, ...
The proton is always in a compound state. Not alone. However, it can be found in the ionized gas. The proton coming to the ionization end of the water combines with the water molecule to bring the hydronium ion (H3O+) into the water. The bond between the hydrogen atoms is almost ...
Because hydrogen-like atoms are two-particle systems with an interaction depending only on the distance between the two particles, their (non-relativistic) Schrödinger equation can be solved in analytic form. The solutions are one-electron functions and are referred to as hydrogen-like atomic ...
