... off the session with a talk entitled "Development and Implementation of Plasma Sprayed Nanostructured Ceramic Coatings." The goal of the project was the development of cost-effective processes for the implementation of nanostructured ceramic materials for Navy applications. Professor Gell's team looked at controlling plasma spray deposition to improve resistance to sea salt buiTcI-up, to enhance strain tolerance; to improve spallation, cracking, and chipping resistance; and to increase wear, corrosion, and erosion resistance.

... The presentation of Geoffrey Malaisky of Technology Intelligence International was entitled "Opportunities and Barriers for Innovative Nanotechnology Applications." Dr. Malafsky listed a number of the National Nanotechnology Initiative grand challenges, including the vision of "nanostructured materials by design," and showed several examples of molecular control, electronic tailoring, and innovative nanomanufacturing.

... properties (e.g., consolidation versus phase equilibria ~ must be understood nonequilibrium structures result, and interfaces or surfaces can create changes in the developing structure. The interfaces are the barrier for exchange spring magnet performance (the spacing across grain boundaries needs to be controlled)
