In a perfect sample, each sulfur atom has two valence electrons that bind to two molybdenum electrons. However, where a sulfur atom is missing, these two molybdenum electrons are left unsaturated ...

In addition, sulfur can also form four-coordinate 'hypervalent' bonds, where its formal number of valence electrons exceeds eight. Compounds containing these bonds are known as sulfuranes.

Transition metal valence state, a key property steering heterogeneous catalysis, has remained underexplored for its role in tuning S cathode kinetics in Li–S batteries. This study reported that ...

In the early 1990s, Jacqueline Barton, the John G. Kirkwood and Arthur A. Noyes Professor of Chemistry at Caltech, discovered an unexpected property of DNA--that it can act like an electrical wire ...
