Times Cited Count：227 Percentile：97.9(Materials Science, Multidisciplinary)Carbon (C)-doped anatase TiO photocatalysts have been prepared by the oxidative annealing of TiC powders at 623 K for 50-100 hrs. From XRD and XPS analysis, it is clear that C is incorporated into O site of the TiO lattice. Diffuse reflectance spectroscopy (DRS) showed that the optical absorption edge of the C-doped anatase TiO shifted to lower energy compared with that of pure anatase TiO. The decomposition of methylene blue (MB) adsorbed on the C-doped sample was observed under a visible light range of 420-500 nm. We conclude that substitution of C for O in the TiO leads to a photocatalytic decomposition of MB under visible light irradiation.

Times Cited Count：3 Percentile：15.63(Physics, Applied)This paper describes the experimental result of the interaction between a high-Tc superconductor and charged particles (plasma). This study is expected for the interaction between the charged particle and superconductor in the group, high-Tc superconducting wiggler for electron beam of FEL (collaboration with Prof.Matsuzawa) and high-Tc superconducting tube for beam guiding published in the journal "Nature".
