  • Publication number: 20190203151
    Abstract: Provided is a lubricant base stock, a lubricating oil including the lubricant base stock and a method for improving viscosity temperature performance or viscosity index of an engine or other mechanical component lubricated with the lubricating oil. The lubricant base stock includes one or more liquid crystals represented by the formula: R1-(A)m-Y—(B)n—R2 wherein R1 and R2 are the same or different and are a substituted or unsubstituted, alkyl or alkoxy group having from 0 to 24 carbon atoms; A and B are the same or different and are a cycloaliphatic group or aromatic group, provided at least one of A and B is an aromatic group; Y is a covalent bond, —CH2-CH2-, —CH?CH—, —C?C—, —OCOO—, —COO—, —CO—, —CSO—, —CSS—, —CS—, —O—, —S—, —SO—, —SO2-, —CH2O—, —OCH2O—, —NO—, —ONO2, —COOH, —OH, or —C?N; and m and n are independently 0, 1, 2 or 3. The lubricant base stock has a kinematic viscosity of 2 cSt to 28 cSt at 40° C., and 1 cSt to 12 cSt at 100° C.

  • Publication number: 20190203144
    Abstract: Methods are provided for lubricating oxygenated diamond-like carbon surfaces to reduce friction while reducing or minimizing wear on the surface. A diamond-like carbon surface layer having a surface ratio of oxygen to carbon of 1:15 or more can be lubricated using a lubricant oil that includes a molybdenum-based friction modifier additive, a tungsten-based friction modifier additive, or a combination thereof. The Mo-based friction modifier (and/or other friction modifier based on a Group VI metal) can be selected based on the Gibbs free energy of adsorption (?G) for the friction modifier on an oxygenated diamond-like carbon surface. Use of a Group VI metal-based friction modifier having a ?G of adsorption with a sufficiently large magnitude can reduce friction at the surface of the oxygenated diamond-like carbon while causing a reduced or minimized amount of wear during lubrication.

  • Publication number: 20190203138
    Abstract: A composition for enhanced heat transfer fluid performance. The composition includes at least one base heat transfer fluid. The at least one base heat transfer fluid undergoes one or more phase changes in a heat transfer process. The heat transfer process includes a heated zone and/or a cooled zone. The one or more phase changes increase heat removal from the heated zone and/or increase heat rejection in the cooled zone, as compared to heat removal from a heated zone and/or heat rejection in a cooled zone of a heat transfer process having a base heat transfer fluid that does not undergo one or more phase changes. The base heat transfer fluids can exhibit liquid crystal behavior (e.g., heat transfer fluids having nematic, smectic or discotic liquid crystals). A method for conducting heat transfer in a heating and/or cooling system using the compositions comprising the base heat transfer fluids.
