In a relatively short time, the field of nanostructured materials has expanded from a novel area of research to a technology with a significant and rapidly growing commercial sector. This proceedings contains papers on the following topics: Synthesis and Processing of Nanoparticles and Nanostructured Assemblies; Fabrication and Properties of Nanocomposites; Characterization and Properties of Nanomaterials; and Industrial Development and Applications of Nanomaterials. Proceedings of the symposium held at the 105th Annual Meeting of The American Ceramic Society, April 27-30, in Nashville, Tennessee; Ceramic Transactions, Volume 148.
