Provided are: an alkali metal titanium oxide having a uniform composition and that is such that there are no residual by-products having a different composition or unreacted starting materials; and a method for producing a titanium oxide and proton exchange body obtained by processing the alkali metal titanium oxide. The method produces an alkali metal titanium oxide by firing the result of impregnating the surface and inside of pores of porous titanium compound particles with an aqueous solution of an alkali metal-containing component. The alkali metal titanium oxide is subjected to proton exchange, and with the proton exchange body of the alkali metal titanium oxide as the starting material, the titanium oxide is produced through a heat processing step.

Method of preparing magnetostrictive material in microgravity environment

A method of fabricating a crystal thin plate of a substance capable of forming a crystal, wherein a molten layer of the substance formed on a support is cooled in the atmosphere of an inert gas or in vacuum at a rate of 10-300&deg; C. per second under a micro-gravity environment to solidify and crystallize the molten layer. The cooling is performed by contacting a portion of the support with a cooling medium.

A composite material having a plurality of laminated polysilylenemethylene layers each having an inside region adjacent to a surface thereof in which nanoparticles of a metal of Au, Pt, Pd, Cu or Ag are dispersed. The composite material is produced by heating a layer of disilacyclobutane overlaid with a layer of nanoparticles of the above metal to polymerize the disilacyclobutane. The above procedure is repeated at least once more.

Composite material containing fine particles of metal dispersed in polysilylenemethylene and process for the preparation thereof

A method of preparing a crystalline or amorphous material, wherein a droplet of a melt of a metal-containing material is cooled in the atmosphere of an inert gas or in vacuum and in a microgravity environment to solidify the droplet. The cooling is performed by impingement of the droplet prior to solidification against a cooling surface.

Method of preparing crystalline or amorphose material from melt

A method of detecting an ultraviolet laser beam, which includes irradiating a detector with the ultraviolet laser beam to produce photoluminescence from the detector, and sensing the photoluminescence. The detector includes a specific polysilmethylene compound or a specific polysiloxane compound. A method of recording an information is also disclosed which includes exposing a photosensitive layer to an ultraviolet laser beam according to the information. The photosensitive layer includes a specific polysilmethylene compound or a specific polysiloxane compound. By irradiating the exposed photosensitive layer to a reference ultraviolet laser beam, the recorded information is read.
