Patent number: 7871533Abstract: The present invention relates to compositions of a nanofluid, which comprises a thermal transfer fluid and carbon nanoparticles. The nanofluid may be hydrophilic nanofluids, such as a coolant, or hydrophobic nanofluids, such as nanolubricants or nanogreases. In particular, the present invention provides a homogenous hydrophilic nanofluid, which contains soluble carbon nanotubes in the hydrophilic thermal transfer fluid. The present invention also provides a nanogrease, which is a sustainable dispersion of solid carbon nanotubes in a hydrophobic thermal transfer fluid. The solid carbon nanotubes function as both as a thickener to modulate viscosity and as a solid heat transfer medium to enhance thermal conductivity and high temperature resistance.Type: GrantFiled: July 28, 2006Date of Patent: January 18, 2011Assignee: South Dakota School of Mines and TechnologyInventors: Hong Haiping, John Andrew Waynick

Patent number: 6054418Abstract: A process for sulfurizing a composition of unsaturated fatty ester is described in which said composition is reacted with elemental sulfur in the presence of a promoter that consists of at least one compound with an amine group and in the presence of water. When the sulfur-containing product is separated from an aqueous phase that contains the compound with an amine group, the latter can be reused for several successive sulfurations without substantial loss of activity of the promoter. The compositions of unsaturated fatty esters can be used as additives for lubricating oils or fats.Type: GrantFiled: March 18, 1997Date of Patent: April 25, 2000Assignee: Institut Francais du PetroleInventors: Thierry Lacome, Bruno Delfort, Maurice Born
