Ruthenium‐Based Single‐Atom Alloy with High Electrocatalytic Activity for Hydrogen Evolution
Advanced Energy Materials, 2019Highly efficient and stable catalysts for the hydrogen evolution reaction, especially in alkaline conditions are crucial for the practical demands of electrochemical water splitting.

Flavin has long been known to function as a single electron reductant in biological settings, but this reactivity has rarely been observed with flavoproteins used in organic synthesis.

Alkynylation of Csp2 (O)-H Bonds Enabled by Photoredox-Mediated Hydrogen-Atom Transfer.
Angewandte Chemie, 2017The development of new hydrogen-atom transfer (HAT) strategies within the framework of photoredox catalysis is highly appealing for its power to activate a desired C-H bond in the substrate leading to its selective functionalization. Reported here is the

Nature, 1980
Silvera and Walraven's report (Phys. Rev. Left. 44, 164; 1980), that they have succeeded in stabilizing bulk atomic hydrogen, suggests that the preparation of superfluid hydrogen may become a practical proposition in the not too distant future.

The 13th international winterschool on electronic properties of novel materials- science and technology of molecular nanostructures, 1999
Contrary to nitrogen and phosphorous, atomic hydrogen is not stable in C60 at room temperature. However, recently it was reported that hydrogen can be stabilized the a cube-like cage of Si8O12. In the present experiment the endohedral system H@Si8O12Et8 (Et=ethyl) was produced by ion implantation using ion implantation on a growing Si8O12-film.

In non-relativistic theory the hydrogen atom is one of the few cases for which the Schrodinger equation may be solved exactly. For this to be possible the proton and electron are assumed to be spinless, and the only role that the proton plays is to provide an attractive Coulombic potential; the finite mass of the proton may, of course, be taken into ...

Quantum Mechanics of the Hydrogen Atom
1983In this chapter, we shall solve the Schrodinger equation of the hydrogen atom. For our calculations, we will not initially restrict ourselves to the Coulomb potential of the electron in the field of the nucleus of charge Z, V(r) = − Ze 2/(4πe0 r), but rather will use a general potential V(r), which is symmetric with respect to a centre.

Bohr’s Model of the Hydrogen Atom
1983In the following chapters we shall take up the detailed analysis of the spectra of atoms in every wavelength region. The most important sources of information about the electronic structure and composition of atoms are spectra in the visible, infrared, ultraviolet, x-ray, microwave and radio frequency ranges.
