Ceramic Shatters Longstanding Record for High-Temperature Superconductivity at Ambient Pressure

Physicists at the University of Houston, Argonne National Lab, and Intellectual Ventures report that pressure quenching--using a burst of deep cold and high pressure--"locks in" the high-temperature superconducting behavior of a well-studied ceramic so that it continues to superconduct even when the pressure is removed and the materials warms.
