New study discovers unexpected role of 4f-orbital covalency in driving chemical reactivity

The willingness of the 4f orbitals of lanthanide metals to participate in chemical reactions is as rare as their presence in Earth's crust. A recent study, however, witnessed the 4f orbital in a cerium-based compound actively participate in bond formation,

Microwaves’ non-thermal effects on a chemical reaction demonstrated for first time

A low-temperature chemical reaction between helium ions and carbon monoxide can be slowed by microwave excitation of the carbon monoxide, researchers in Switzerland have shown. The result shows that microwaves can have non-thermal effects on chemical reaction rates, and could be important in astrochemistry.
