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 ...

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

Chemical oxygen demand (COD) is a crucial metric for assessing the organic pollution load in water, reflecting the amount of oxygen required to oxidise organic compounds. Ultraviolet–visible (UV–Vis) ...

Earth formed within such a precise “Goldilocks zone” for oxygen that a 5% change would have prevented life from emerging.
