||Nanostructured materials, including nanoparticles, nanowires, etc. hold great promise to enable a broad range of new applications as well as improve existing technologies because of their unique physical and chemical properties. This includes high energy conversion efficiency fuel cells, photovoltaic solar cells, smart materials,piezoelectric and ferroelectric devices, energy storage systems, high performance multifunctional sensors, and structural materials, including ceramics, that work under extreme environments. However, many barriers still exist in understanding and controlling the processing of nanostructured materials. In particular, new powder synthesis and processing is needed for the fabrication of homogeneous green or multi-functional hybrid composites, and microstructure evolution must be controlled to preserve the size and properties of the nanostructures in the finished materials. Also, novel nanostructure designs are highly needed at all stages of nanoparticle-based material formation process to enable unique performances, low cost, and green engineering. Great challenges also remain on the composition and morphology control of multi-component functional and smart oxide nanomaterials. This symposium will focus on the following general topics, 1) Processing and characterization to preserve and improve nanoscale size, structure, and properties, 2) Novel design and understanding of new nanoparticle-based materials, such as new synthesis approaches, templating, and 3D assembly technologies, 3) Applications of nanoparticle assemblies, composites, and ceramic nanomaterials, especially in energy systems such as fuel cells, batteries, and solar cells, 4) synthesis methods and growth mechanisms of ceramic nanowires, 5) theoretical and computational study of the growth behavior in low dimensions; and 6) study and understanding of the nanometer scale properties in ceramic nanomaterial systems.
