Abstract: A first resin, a curable precursor of a second resin that differs from the first resin, an inorganic material and a solvent are blended and a mixed solution is prepared. Next, by heating the mixed solution, the solvent is removed and the curable precursor is cured, and an organic-inorganic composite is obtained that comprises a composite resin having a co-continuous phase-separated structure formed from a three-dimensionally continuous first phase made of the first resin and a three-dimensionally continuous second phase made of the second resin, and an inorganic material that is localized at the interface between the first phase and the second phase.

Abstract: A method for producing erythrose, comprising subjecting glucose to a decomposition reaction using water at a super-critical state or at a sub-critical state as the solvent therefor, and a method for producing erythrose from glucose, wherein the reaction time is set to a time period suitable for a high production level of erythrose and a low level of contaminated by-products.

Abstract: Granular diamond suitable for use as an abrasive grain for polishing is synthesized from gaseous phase by a process for the synthesis of granular diamond, comprising subjecting a mixed gas containing an organic compound and hydrogen to a treatment to form plasma and depositing diamond on substrate grains dispersed and fluidized in the resulting plasma space, characterized in that the substrate grains are dispersed and fluidized by the mixed gas fed at a flow rate of at least the terminal velocity of the grains and an AC or DC electric field is applied to a zone whose grain concentration in the space is in the range of 1 to 20% by volume.

Abstract: An apparatus and a method of producing a high density fiber reinforced composite material operate for lowering the porosity of a porous fiber reinforced composite material. A large number of particles arranged in a reaction tube are pushed up by the pressure of gases flowing from a gas inlet port toward a gas outlet port to enter floating states and to collide with the porous fiber reinforced composite material which is fixed in the reaction tube. In this state, matricies are formed in pores of the porous fiber reinforced composite material through chemical vapor infiltration. The large number of floating particles prevent an adhesion between the surface of the porous fiber reinforced composite material and blocking with soot, while preventing the pores from blocking with soot.
