The oxygen evolution reaction (OER) on solid catalysts is generally believed to proceed via a four-step process, with each step involving distinct intermediates 1,2,3,4,5,6,7,8,9,10,11,12,13,14. The ...

Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely fossilize. Determining when exactly a particular group of microbes first ...

Oxygen is a cornerstone of chemistry, largely because it is so good at building the organic molecules that make up our world. Some oxygen-based compounds called peroxides are famous for being highly ...

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 ...

Octopuses pump blue blood through three separate hearts, a biological arrangement that depends entirely on copper rather than ...

Bacterial evolution and oxygen adaptation: A timeline built from genomic, fossil, and chemical data. Colors show oxygen states: anaerobic (blue), aerobic (red), and proportion of aerobic lineages in ...
