Transmission electron microscopy (TEM) is one of the highest resolution analysis methods of materials. The three dimensional recognition of the materials is difficult by TEM because the observation data is projection images through the materials. In

Idiomorphic and prismatic K2Nb8O21 crystals were successfully grown by the isothermal evaporation of KCl flux. On the basis of their aspect ratio, the crystals were divided into two morphological types, that is, whisker (needle) and prism. Growth was

The electrical resistivity and microstructure of nano-carbon materials, such as anisotropic coal tar pitch (pitch C) and polyparaphenylene (PPP), were investigated. The resistivity of the samples measured under applied pressure decreased as the packi

In order to clarify the mechanism of Li-ions insertion/deinsertion into/from polyparaphenylene (PPP)-based carbons, the PPP carbonization has been analyzed. The weight loss of the PPP carbonized samples increased at a faster rate in the temperature r
