Carbon nanotubes, graphenes, and related nanostructures such as fullerenes, and other non-carbon nanotubes and nanostructures (materials in the B-C-N system, including boron nitride, and boron), have attracted tremendous attentions for their unique structures and intriguing properties. These nanomaterials have been widely investigated, from synthesis, structure and property characterization to applications in electronic devices, field emission displays, biological and chemical sensors etc. This symposium will emphasize both solid-state and molecular aspect of these carbon and non-carbon nanostructures. It will bring together researchers from different disciplines to discuss the fundamentals of theory, synthesis, characterization, chemical and biochemical methods for purification and assembly, toxicity and bio-compatibility, and applications in electronics, chemistry, biochemistry, biomedicine, etc.
