Researchers have produced two surprising compounds of nitrogen and the rare earth metal yttrium under very high pressure. The new polynitrides contain ring- and spiral-shaped crystal structures of ...

Soil erosion is widely known for degrading land and reducing agricultural productivity. But new research shows it may also ...

Chemists have determined the structure of the complex that forms when N2 binds to an iron-sulfur cluster, offering clues as to how microbes use nitrogenase enzymes to convert atmospheric dinitrogen ...
