Abstract: A method of producing nanoparticles comprises effecting conversion of a nanoparticle precursor composition to the material of the nanoparticles. The precursor composition comprises a first precursor species containing a first ion to be incorporated into the growing nanoparticles and a separate second precursor species containing a second ion to be incorporated into the growing nanoparticles. The conversion is effected in the presence of a molecular cluster compound under conditions permitting seeding and growth of the nanoparticles.

Abstract: This invention provides a process for producing a membrane electrode assembly which has high and stable catalytic activity, and suppressed deterioration in catalytic activity during operation, and can prevent a deterioration in performance attributable to a structural factor of the membrane electrode assembly. The process comprises the step of, after the washing/removing step, drying the catalyst electrode in an atmosphere having a lower oxygen partial pressure than the air. The anode/cathode is a covered catalyst electrode having a structure formed by supporting/depositing a catalytically active material composed mainly of platinum/ruthenium subjected to the potential holding step, the washing/removing step, and the drying step, on a porous electroconductive carrier to cover at least a part of the porous electroconductive carrier with the ion conductive material.

Abstract: A method for producing nanostructures on a substrate, by dripping a solution of nanostructure-forming material in water onto the substrate heated to a temperature above the temperature at which a drop of the solution is initially suspended on a vapor cushion after being applied by dripping onto the substrate, with nanostructures being formed when the drops evaporate.
Abstract: In the present invention, an insulating material is applied onto a substrate in a coating treatment unit to form a coating insulating film. The substrate is heated in the heating processing unit, whereby the coating insulating film is hardened partway. A brush is then pressed against the front surface of the coating insulating film in a planarization unit and moved along the front surface of the coating insulating film, thereby planarizing the coating insulating film. The substrate is then heated to completely harden the coating insulating film. According to the present invention, the coating film can be planarized without using the CMP technology.
