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.

Method of fabricating crystal thin plate under micro-gravity environment

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.

Method of detecting ultraviolet laser beam and method of recording

There are disclosed a catalyst which comprises a carrier composed of a porous silicon carbide or a porous silicon nitride prepared by a silicon-accumulated biomass and a catalytic substance supported thereon, and a method for preparing a catalyst which comprises supporting a catalytic substance on a porous silicon carbide or a porous silicon nitride prepared by subjecting a silicon-accumulated biomass to heat treatment under an argon or a nitrogen atmosphere.

Method for preparing a catalyst supported on silicon carbide or silicon

A silica-containing material such as silica sand, a carbonized biomass or biomass ash is converted into carbon tetrachloride by reaction with chlorine gas at an elevated temperature in the presence of a carbonaceous material such as coke, and sulfur or a sulfur compound. The reaction may be suitably performed in the further presence of a potassium compound.
