Featured Article: Carbide
In chemistry, a carbide is a compound of carbon with a less electronegative element. Many carbides are important industrially; for example, calcium carbide (CaC2) is a feedstock for the chemical industry and iron carbide (Fe3C, cementite) is formed in steels to improve their properties.
Popular Article: Phosphorus cycle
The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the geosphere, hydrosphere, and biosphere. Unlike the other major biogeochemical cycles (oxygen, carbon, nitrogen, and water), the atmosphere does not play a significant role in the movements of phosphorus because phosphorus and phosphorus-based compounds are usually solids at the typical ranges of temperature and pressure found on Earth.
