Nobody completely understands superconductors. So fathom how James S. Schilling, Ph.D., led a team that makes the phenomenon work better. Schilling, a professor of physics in Arts & Sciences at Washington University in St. Louis, collaborated with recent doctoral graduate Takahiro Tomita and scientists at Argonne (Ill.) National Laboratory to determine whether one region in superconductors, called grain boundaries (GB), are oxygen deficient. Such oxygen deficiency impairs superconductor performance.
