Nanocarbon Materials: Synthesis, Characterization and Applications 

I will speak briefly about the discovery of carbon nanotubes (CNT) with emphasis on importance of high-resolution electron microscopy (HRTEM) [1]. Many unique properties of CNT, its basic structure being graphene of a hexagonal network of carbon atoms with hybridized electron orbitals, come from their cylindrical form with nanometer sized diameter. The CNTs having flexible and unique electronic properties have been successfully commercialized as touch-panel electronics devices. Some of new developments in nanocarbon materials will concern with photothermal properties arising from their excellent light absorbent and functionalization with organic substances. The functionalization allows us to use them in the area of nanobiotechnology [2,3].

Modern electron optical technology including high resolution microscopy, electron energy loss spectroscopy (EELS) [3] and energy dispersive X-ray analysis (EDX) [4] has progressed greatly, and supported widely innovative research on nano-materials. Some of typical examples of atomic-detailed characterizations of nanocarbon materials, CNTs, graphene sheets and related nano-materials will be presented [4-6].
