A carbon nanotube aggregate includes a plurality of carbon nanotubes, a metal compound added to inside and/or outside of each of the carbon nanotubes, and an oxide film that is made of an oxide of the metal compound, and covers an outer periphery of the plurality of carbon nanotubes to define an outer surface of the carbon nanotube aggregate. Since the metal compound is shielded from the atmosphere by the oxide film, separation of the metal compound and reaction of the metal compound with oxygen or water in the atmosphere are suppressed, increasing heat resistance of the carbon nanotube aggregate.

A structure body includes a base material and a siloxane based molecular membrane formed on the base material by use of an organic compound represented by Formula (1) or Formula (2): wherein any one of R1 to R5 is an amino group, others of R1 to R5 are each independently hydrogen or an alkyl group, R7 to R9 are each independently any one of hydroxy group, alkoxy group, alkyl group, and phenyl group on condition that one or more of R7 to R9 are each independently a hydroxy group or an alkoxy group, and R6 is an alkyl group.

A supercooling release material, which releases a supercooled state of a cold storage material including one or more types of alkylammonium halide aqueous solutions that generate a hydrate by being cooled to a hydrate generation temperature or lower, includes: an alkylammonium ion included in the cold storage material; and a metal halide ion which has, as a constituent element, a halogen element included in the cold storage material. The supercooled state of the cold storage material can be reliably released by using the supercooling release material having such a configuration.

A heat transfer system has an energy converter, a heat transfer medium, a transfer part, and a heat exchanger. The energy converter converts an energy of an energy source into an energy in a different state and generates a heat while converting the energy. The heat transfer medium is in a liquid state and receives the heat from the energy converter. The heat exchanger dissipates the heat from the heat transfer medium to an outside of the heat transfer system. The heat transfer medium contains HO and a solute compatible with the HO. The solute has a molecular structure including two hydroxyl groups. A length of a binding chain between an oxygen atom of one of the two hydroxyl groups and an oxygen atom of an other of the two hydroxyl groups is shorter than a length of a binding chain between two hydroxyl groups of an ethylene glycol molecule.

Heat transfer system
