Researchers at the National Science Foundation (NSF) and Princeton University are exploring the properties of magnesium diboride (MgB2), a compound thought to allow the passage of electric current with no resistance. In copper oxide superconductors, the interfaces between material crystals interfere with the flow of electric current. This is not the case with MgB2. Potential applications: computers and electronics. The process of making the superconducting compound into wire or other practical devices is expected to take several years.
