Of the 92 naturally occurring elements, add another to the list of those that are superconductors. James S. Schilling, Ph.D., professor of physics in Arts and Sciences at Washington University in St. Louis, and Mathew Debessai, Ph.D., - his doctoral student at the time - discovered that europium becomes superconducting at 1.8 K (-456 F) and 80 GPa (790,000 atmospheres) of pressure, making it the 53rd known elemental superconductor and the 23rd at high pressure...
