... particles, and ceramic powders. The processes ranged from nanomilling and mechanical alloying, to thermal spray, powder consolidation, and other additive processes, to the processing of nanocomposites.

... on mechanical properties such as yield, ultimate tensile strength, and modulus of elasticity that inclicatect that nanoscale materials could exhibit better wear or fatigue resistance than their conventional counterparts, contrary to some other findings for high cycle fatigue. Examples of current technologies include the creation of nanofoils by rotating a 2-foot-wide strum in the electrolyte and peeling off the resulting foil continuously, at a production rate of 4 to 5 tons/machine/year.

... Chris Berndt of SONY Stony Brook spoke on his topic, "The Unique Mechanical Properties of Thermal Spray Coatings Interpreted from a Nanostructural Viewpoint." Professor Berndt gave a thorough update on thermal spray that included processing of thermal barrier coatings, control of the process, including an understanding of defect generation, and effect upon performance. The basic need is to understand the relationship between the processes, the selection and optimized use of feedstock, and the resulting performance of the structures.

... several challenges and potential applications: Preventing the composite oxides from reacting with one another uncler the reversemicroemuision-mediated synthesis conditions so that the synthesis method can be applied to (levelop other complex-oxicle catalysts; Detecting and distinguishing trace levels of toxic gases, rapid response, and response reproducibility; and Applications: biomaterials, catalysts, gas sensors, molecular sieves, and nanowires. In the follow-up question-and-answer portion of the session, the audience and session speakers addressed scale-up, producibility, science versus technology, and personnel needs: Thomas Gates of NASA Langley Research Center asker!

... Professor Berndt also raised a concern about the proprietary nature of private industry research. Limited access to research findings may slow advances in nanotechnology or result in duplication of federal research efforts.
