08/02-- Srinivasan Chandrasekar, a professor of industrial engineering at Purdue University, uses an atomic force microscope to view a metal containing "nanocrystals," or tiny crystals that are often harder, stronger and more wear resistant than the same materials in bulk form. Researchers at Purdue University recently made a surprising discovery that could open up numerous applications for metal nanocrystals. The research engineers have discovered that the coveted nanocrystals are produced in common machining processes and are contained in scrap chips that are normally collected and melted down for reuse.
