Arthur Louis Ruoff is the class of 1912 Professor of Engineering Emeritus. Within the Department of Materials Science and Engineering, he is a member of the graduate fields of: Applied and Engineering Physics, Earth and Atmospheric Sciences and Materials Science and Engineering. His research interests include the behavior of materials at extreme pressures, energy and economics. He is a winner of the Bridgman award for his outstanding ultrapressure research. Ruoff served as department director for ten years. He was member of the committees that wrote the research proposals for the Cornell Center for Materials Research, the Cornell Nanofabrication facility and the Cornell High Energy Synchmotor Source. He is the author of 317 scientific publications and three books, the latest "The Declaration of Energy Independence" to be available in June 2012.

Research Interests

Ruoff created the static multimegabar research area (1 Mbar= 100 GPa); the pressure at the deepest spot in the ocean is 0.1 GP. His group carried out x-ray diffraction studies at 216 GPa (1987) and 255 GPa (1988), 416 GPa (1990) exceeding, for the first time, the pressure at the center of the earth (361 GPa), and at 560 GPa (1992). This is a factor of over 60 higher than reached by Nobel Prize winner Percy Bridgman for his high pressure studies. His group made oxygen into an excellent metal at 95 GPa in 1990 (confirmed by Shimizu in 1998). Ruoff's group made sulfur metallic at 95 GPa in 1992 (confirmed by Struzkin et al in 1996). His group showed that H2 still has an energy band gap of 1.9 eV at 342GPa in 1998 (confirmed by Zha et al in 2012 at 360 GPa). He is currently preparing for experiments to exceed 1000GPa (1TPa).

Teaching Interests

Lecturing in graduate course work and undergraduate Materials Science courses. Development of audio-tutorial undergraduate courses, learning center, etc.

Service Interests

Has been a consultant to numerous industries and laboratories on high pressure phenomena, including diamond production, to several industries on multimedia instruction. Has presented invited lectures at international conferences in Canada, Sweden, Mexico, Brazil, Japan, India, Greece, Russia, Iran, England, Scotland, Sweden, Germany, East Germany, France, Poland, Portugal, Italy, and Holland, as well as within the United States.
