A grease composition containing a base oil and a calcium complex soap as a thickening agent, wherein a C18-22 straight chain, substituted or unsubstituted higher fatty acid; a substituted or unsubstituted aromatic monocarboxylic acid having a benzene ring; a C2-4 straight-chain saturated lower fatty acid; and a substituted or unsubstituted saturated dicarboxylic acid are used as carboxylic acids constituting the calcium complex soap.

An organogel including a base fluid, cetyl alcohol, and a gelling agent provided in an amount to cause the fluid to change from a liquid state to a gelled state at temperatures below at least 25° C. A nanofluid including an organogel and a nanoparticle component which permits the nanofluid to change from a liquid state to a gelled state at temperatures below at least 25° C., the gelled state helping to maintain the nanoparticle component suspended throughout the base fluid; and a method for preparing a gelled nanofluid.

A lubricating composition which, when used with a device for clamping an article, such as a chuck, produces excellent lubricating properties whilst remaining strongly adhered to metal parts in a clamping mechanism of the device and showing enhanced chemical and physical resistance to fluids such as cutting fluids.

A lubricant additive may be synthesized by forming a nanohybrid of a transition metal dichalcogenide and a metal borate, forming a base oil, and then dispersing the transition metal dichalcogenide into the base oil. An exemplary nanohybrid may be synthesized by forming a first solution by adding a borax solution to an aqueous solution of a metal source, forming a second solution by adding ethanol to the first solution, forming a mixture by mixing the transition metal dichalcogenide with the second solution, and heating the mixture at a temperature of 180° C. to 230° C. and a pressure of 5 to 20 bar under a nitrogen atmosphere.

The present disclosure relates to a lubricant composition including a base oil, a thickener and a thickener supplement, and a method of manufacturing the same. The lubricant composition of the present disclosure is effective at improving performance at high-temperature by maintaining the evaporation amount and friction characteristics even at high temperatures, thus inhibiting oil contamination of powertrain parts and the like and maintaining sticking phenomenon even in a high-temperature environment, thereby increasing the durability of parts.
