Class C—Nonmetals or acidulous elements possess from five to seven free valence electrons and are therefore strongly electro-negative. They form the acids.

Electrons play many roles in solid materials. When they are weakly bound and able to travel—i.e., mobile—they can enable ...

Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a ...

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...

As few as five electrons in a semiconductor can exhibit collective behaviour, forming a “Coulomb liquid”, according to researchers in Europe. This extends the study of correlated systems to electron ...

Researchers from the University of Hong Kong studying the structure of 2D materials have predicted new types of phase transitions that have yet to be seen in experiments ...

Quantum dots beat traditional photosensitizers at their own game. They tackle reactions once thought too tough for ...

Herein, we show for the first time that thiolate ligands can play an important role in promoting 2e- oxo atom transfer with nonheme iron. We examine the mechanism of oxo atom transfer to a cis ...

Chemdex: quantification and distributions of valence numbers, oxidation numbers, coordination numbers, electron numbers, and covalent bond classes for the elements.

A two-step reaction mechanism was derived, with this mechanism involving rapid • OH substitution on either sulfur atom, leading to cleavage of the disulfide bond and formation of Cys–SOH/R–S • and Cys ...
