1. Superconductivity Marker
During the 1980s, Professors Allen Hermann and Zhengzhi Sheng of the Department of Physics were in the vanguard of research in superconductivity – the phenomenon whereby direct current (DC) electricity, once started, can flow essentially forever. The thallium-based material they discovered at Arkansas held the world's record for high temperature, 125K, for five years (1988-93) and drew international attention to the university. Their work led to numerous patents and a manufacturing agreement, as well as further advances in high-density electronics.
Erected 1999 by Arkansas Alumni Association.
