As a recent leap in green chemistry, scientists have unveiled a new catalyst that enables high yields of sulfones using molecular oxygen -- at close to room temperature. By fine-tuning the structure ...

A major discovery is reshaping how scientists think about catalysts. Researchers have, for the first time, captured oxygen ...

A new approach reveals unexpected ways oxygen can bind to rare metals. Iron plays a central role in how the body uses oxygen. In hemoglobin, it binds dioxygen, a pair of oxygen atoms, allowing blood ...

Photodynamic treatment of cancer is based on administering an initially inactive substance that is only activated in the tumor via targeted light irradiation. It then generates reactive oxygen species ...
