摘要:
A porous metal sheet (489) is used as an electrode substrate and the surface of a metal constituting the porous metal is roughened by etching. A plating layer of a catalyst (491) is formed on the surface on which irregularities are formed. This obtained electrode material is used as a fuel electrode (102) or an oxidizer electrode and these electrodes are bound with the solid electrolyte film (114).
摘要:
A substance-encapsulating carbon nanohorn aggregate which has improved chemical stability by isolating the encapsulated substance from outside and which is useful as a targeting material which can be led from the outside of the body or as a contrast medium by holding the encapsulated substance in an aggregated form, and a process for producing the same are provided. The substance-encapsulating carbon nanohorn aggregate is characterized in that the encapsulated substance is aggregated in a central part of the carbon nanohorn aggregate or a neighborhood thereof with being isolated from outside. The process includes aggregating a substance to be encapsulated in a central part or a neighborhood thereof by a heat treatment.

摘要:
The present invention provides: a carbon nanohorn composite including a carbon nanohorn, a substance encapsulated in the carbon nanohorn, and a polyamine adsorbed by chemical reaction firmly to a surface functional group present on the opening part on the surface of the carbon nanohorn, wherein the release amount and release rate of the encapsulated substance can be controlled using the difference in size, substituent or three-dimensional structure of the polyamine, which is used as a plug; a method of controlling the release of the encapsulated substance; and a process for producing the carbon nanohorn composite. The release amount and release rate of the substance encapsulated in the carbon nanohorn composite is controlled by selecting a polyamine molecule, which plugs the opening part formed in the carbon nanohorn by oxidation, by its size, substituent or three-dimensional structure.

摘要:
A nanocarbon aggregate including a graphite aggregate including a graphene sheet having a petal shape and a nanohorn. The petal-shaped graphite aggregate achieves a reduction in the particulate size and a higher dispersibility by allowing the edge of the petal shape to locally absorb a metal, a metal complex and a metal oxide. The nanocarbon aggregate is used for a catalyst support.
