Novel Gold Catalysts for the Oxidation of Carbon Monoxide at a Temperature far Below 0 °CAbstract
A variety of gold catalysts can be used to catalyze the oxidation of carbon monoxide at temperatures as low as −70 °C and are stable in a moistened gas atmosphere. The novel catalysts, prepared by coprecipitation, are composed of ultra-fine gold particles and one of the oxides of 3d transition metals of group VIII, namely, Fe, Co, and Ni.

Layered Lithium Insertion Material of LiCo1/3Ni1/3Mn1/3O2 for Lithium-Ion BatteriesAbstract
Layered LiCo1/3Ni1/3Mn1/3O2 was prepared by a solid state reaction at 1000 °C in air and examined in nonaqueous lithium cells. LiCo1/3Ni1/3Mn1/3O2 showed a rechargeable capacity of 150 mAh g−1 in 3.5–4.2 V or 200 mAh g−1 in 3.5–5.0 V. Operating voltage of Li / LiCo1/3Ni1/3Mn1/3O2 was by 0.2–0.25 V lower than that of a cell with LiCoO2 or LiM... ...

PRODUCTION OF CO AND CH4 IN ELECTROCHEMICAL REDUCTION OF CO2 AT METAL ELECTRODES IN AQUEOUS HYDROGENCARBONATE SOLUTIONAbstract
The total analysis of gaseous and soluble products was carried out in the electrochemical reduction of CO2 (current density 5 mA cm−2) on various electrode metals. HCOO− was predominantly produced at Cd, In, Sn, and Pb cathodes. Ag and Au principally gave CO. CH4 was formed in an appreciable amount at Cu cathode.

Carbon-doped Anatase TiO2 Powders as a Visible-light Sensitive PhotocatalystAbstract
Carbon-doped TiO2 powders in an anatase phase colored yellow were fabricated by oxidative annealing of TiC. Carbons were located at oxygen sites. The carbon substitution caused the absorbance edge of TiO2 to be shifted to the higher wavelength region. Carbon-doped TiO2 showed photocatalytic activities for the decomposition of IPA to CO2 via ... ...

Photocatalytic Activity of S-doped TiO2 Photocatalyst under Visible LightAbstract
In order to effectively utilize visible light in photocatalytic reactions, we have developed S-doped TiO2 particles. They show strong absorption for visible light and high activities for degradation of methylene blue in aqueous solution under irradiation at wavelengths longer than 440 nm. The oxidation state of the S atoms incorporated into ... ...

OXYGEN PERMEATION THROUGH PEROVSKITE-TYPE OXIDESAbstract
The rate of oxygen permeation through La1−xSrxCo1−yFeyO3−δ was found to increase with an increase in Sr or Co content, showing that the permeability was mainly controlled by the amount of oxygen vacancies. The results obtained indicate that mixed conductive perovskite-type oxides are promising materials for oxygen permeation at elevated temp...

Discovery of a Magnetic Ionic Liquid [bmim]FeCl4Abstract
A magnetic ionic liquid, which shows a strong response to magnetic field, has been discovered. We synthesized an ionic liquid by mixing 1-butyl-3-methylimidazolium chloride ([bmim]Cl) and FeCl3, in anticipation of unique magnetic properties due to the possible local ordering of the magnetic anions. The visible absorption spectroscopy has sho... ...

Highly Luminescent Lead Bromide Perovskite Nanoparticles Synthesized with Porous Alumina MediaAbstract
Nanocrystalline lead bromide perovskite was synthesized by rapid self-organization on a mesoporous aluminum oxide film. With UV excitation, the film exhibited an intense green emission with a narrow bandwidth. The photoluminescence intensity is optimized for the conditions of synthesis and the kind of metal oxide.

Formation of Titania Nanotubes with High Photo-Catalytic ActivityAbstract
Titania nanotubes with high photo-catalytic activity were synthesized in laurylamine hydrochloride / tetraisopropyl orthotitanate modified with acetylacetone system. Formation of nanotubes was confirmed by transmission electron microscope images. These titania nanotubes had crystal structure of anatase and showed high photo-catalytic activit... ...

Highly Conductive Room Temperature Molten Salts Based on Small Trimethylalkylammonium Cations and Bis(trifluoromethylsulfonyl)imideAbstract
The electrochemically stable and relatively high conductive room temperature molten salts (RTMS) have been obtained with the use of small ammonium cations such as methoxymethyltrimethylammonium and bis(trifluoromethylsulfonyl)imide. The RTMS showed high conductivity (4.7 mS cm−1 at 25 °C) which is the highest value of all the ammonium based ...
