including the steel industry. Dr. Sudarshan has served as the principal investigator of several programs in the development of diamond thin films, solid lubricants for space structures in conjunction with the European Space Agency, nontoxic lubricants for automobile applications, accelerated corrosion testing, synthesis and consolidation of nanostructured materials, and development of lightweight carbon-carbon pistons. He has been the recipient of numerous awards and honors, including the Design News Award and R&D 100 for the microwave plasma technique Nanogen and for the Plasma Pressure Compaction technique. He has served on numerous committees of the National Science Foundation, the National Institutes of Health, and ASM International. Dr. Sudarshan is the author of more than 125 published proceedings and journal articles and presentations. He is the co-editor of two journals, Materials and Manufacturing Processes and Surface Engineering, and has co-edited 18 books on various aspects of surface modification technologies. He is a fellow of ASM International and the International Federation for Heat Treatment and Surface Engineering.

Richard E.Tressler is professor emeritus in the Department of Materials Science and Engineering at Pennsylvania State University. His research interests include the following: thermodynamic stability of advanced ceramics in energy conversion systems and high-temperature processing plants; improvements in materials and protection schemes through understanding the rate-limiting reactions and local thermodynamic equilibria of the processes that control corrosion and substrate degradation; long-term reliability of advanced structural ceramics, ceramic fibers, and ceramic-ceramic composites under static or cyclic stresses at elevated temperatures in energy-usage and energy-recovery applications; and development of a design database of reliable tensile properties of commercially available materials. Dr. Tressler has served on many NRC committees, including the Committee on Materials Research for Defense After Next, the Panel on Structural and Multifunctional Materials, the Committee on Advanced Fibers for High-Temperature Ceramic Composites, and the Committee on Ceramic Technology for Advanced Heat Engines.

Courtney A.Young is ASARCO Distinguished Professor of Metallurgical Engineering and head of the Department of Metallurgical and Materials Engineering at Montana Tech of the University of Montana, where he has taught for 10 years. His areas of expertise include surface chemistry, electrochemistry, and spectroscopy as applied to all areas of process technology, particularly resource recovery in primary production (i.e., copper, gold, flotation, physical separations, sulfide electrochemistry, and adsorption) as well as secondary production (i.e., cyanide destruction, acid-rock drainage remediation, spent pot liner recycling, and other areas of waste treatment and minimization). Dr. Young has served as principal investigator on numerous research projects and as a consultant for several companies involved in selecting and testing ore-processing options and researching and developing solutions to environmental problems. He is active in professional organizations, including the TMS and the Society for Mining, Metallurgy, and Exploration, from which he has received several awards. He is the author of 100 publications and presentations.
