Doped graphite may superconduct at more than 100 ºC (boiling point of water), according to Pablo Esquinazi and his colleagues at the University of Leipzig, Nature News reports.
Superconductors offer huge potential energy savings when used for electrical power transmission lines, for example, but until now have worked only at temperatures lower than about -110 °C. A superconductor can transmit electricity with zero resistance. At high temperatures (room… read more
