Abstract:
A nanoparticle of a decomposition product of a transition metal aluminum hydride compound, a transition metal borohydride compound, or a transition metal gallium hydride compound. A process of: reacting a transition metal salt with an aluminum hydride compound, a borohydride compound, or a gallium hydride compound to produce one or more of the nanoparticles. The reaction occurs in solution while being sonicated at a temperature at which the metal hydride compound decomposes. A process of: reacting a nanoparticle with a compound containing at least two hydroxyl groups to form a coating having multi-dentate metal-alkoxides.
Abstract:
The present invention addresses the problem of providing spherical zinc oxide particles which have an average particle diameter within a specific range, have excellent monodispersity, and have a high plasmon resonance intensity. Also provided are a process for producing the spherical zinc oxide particles and a plasmon sensor chip obtained using the spherical zinc oxide particles, the chip having high sensitivity and being reduced in angle dependence during measurement. The spherical zinc oxide particles have been doped with one or more metallic elements selected from the group consisting of gallium (Ga), europium (Eu), cerium (Ce), praseodymium (Pr), samarium (Sm), gadolinium (Gd), terbium (Tb), neodymium (Nd), and ytterbium (Yb), have an average particle diameter within the range of 50 to 5,000 nm, and have a variation coefficient in particle diameter distribution within the range of 1.0 to 10%.
Abstract:
An X-ray amorphous magnesium carbonate is disclosed that is characterized by a cumulative pore volume of pores with a diameter smaller than 10 nm of at least 0.018 cm3/g, and a specific surface areas of at least 60 m2/g. The X-ray amorphous magnesium carbonate is produced by reacting an inorganic magnesium compound with alcohol in a CO2 atmosphere. The X-ray amorphous magnesium carbonate can be a powder or a pellet and acts as a desiccant in, for example, production of food, chemicals or pharmaceuticals.

Abstract:
A nanostructured titania semiconductor material termed TSG-IMP having a predetermined crystal size is produced by a sol-gel method by adding a titanium alkoxide to an alcoholic solution, adding an acid to the alcoholic solution, subjecting the acidic solution to agitation under reflux conditions; stabilizing the medium and adding bidistilled water under reflux until gelation; subjecting the gel to aging until complete formation of the titania which is dried and calcined.
