摘要： The present invention provides a lubricant composition suitable for reducing friction between sliding members such as those within a pump for circulating a heat medium of a heat pump device, and a lubricating system using the composition as a heat medium. A lubricant composition 10 of the present invention comprises: an antifreeze liquid 11 containing ethylene glycol; and 0.01 mass % or less of nanodiamond particles 12. The nanodiamond particles 12 are preferably detonation nanodiamond particles. The lubricant composition 10 is preferably a liquid composition for a heat pump. In addition, the lubricating system of the present invention uses the lubricant composition 10 as a heat medium.

摘要： The present invention provides an initial running-in agent composition suitable for forming a low-friction surface (running-in surface) on a sliding member, such as a hard carbon film, in a system in which water is used as a lubricant. The initial running-in agent composition (10) according to an embodiment of the present invention contains water 11 as a lubricant base and nanodiamond particles (12). In the initial running-in agent composition (10), a content of the water (11) is preferably 99 mass % or greater, and a content of the nanodiamond particles (12) is preferably 1.0 mass % or less.

摘要： A carbon dioxide separation membrane according to the present invention includes: an ionic liquid affinitive porous layer (C) having an ionic liquid-containing liquid (A) retained in voids; and an ionic liquid non-affinitive porous layer (B). The ionic liquid affinitive porous layer (C) may contain inorganic materials (for example, metal oxide particles having an average particle size of about 0.001 to 5 μm on a number basis). An average thickness of the ionic liquid affinitive porous layer (C) may be about from 0.01 to 10 μm. The ionic liquid affinitive porous layer (C) may include the ionic liquid-containing liquid (A) at a ratio from 0.1 to 99 parts by volume with respect to 100 parts by volume of voids. It may be a carbon dioxide separation membrane for fertilizing plants with carbon dioxide. The carbon dioxide separation membrane can reduce a size of the carbon dioxide concentrating device and enables smooth operation of the device.

摘要： This ionic liquid-containing laminate includes a porous layer having affinity with ionic liquids (C), said layer holding an ionic liquid-containing liquid (A) within voids therein, and a porous layer lacking affinity with ionic liquids (B). The porous layer having affinity with ionic liquids (C) may include an inorganic material (e.g., metal oxide particles having an average particle size of 0.001 to 10 μm on a number basis). The ionic liquid-containing liquid (A) may include an ionic liquid containing cations selected from ammonium, imidazolium and phosphonium cations, and anions selected from fluorine-containing anions, cyano-containing anions and amino acid-derived anions. The porous layer having affinity with ionic liquids (C) may include 1 to 100 volume parts of the ionic liquid-containing liquid (A) with respect to 100 volume parts of voids therein. The ionic liquid-containing laminate is easily formable, and is able to stably hold (or fix) the ionic liquid while maintaining said liquid in a liquid state.

摘要： A sliding member includes a carbon transfer layer and can superiorly effectively decrease friction and reduce wear. A method produces the sliding member. The sliding member includes a substrate and a carbon transfer layer. The carbon transfer layer is disposed on the surface of the substrate and includes both sp2 bonded carbon and sp3 bonded carbon. The carbon transfer layer preferably has a ratio sp3/(sp2+sp3) of the sp3 bonded carbon to the totality of the sp2 bonded carbon and the sp3 bonded carbon of 0.1 or more.
