Abstract
A use of a hemimellitic acid ester of formula I as a base oil a lubricant composition for lubricating tribological systems. In some embodiments, R1, R2 and R3, are independently of one another: a C5 to C20 aromatic group, a C5 to C20 cycloalkyl group, an unsubstituted, branched or unbranched C1 to C20 alkyl group, and/or a C1 to C5 alkyl group comprising at least one substituent selected from the group consisting of cycloalkyl groups and aromatic groups. In some embodiments, the hemimellitic acid ester of formula I is provided as a mixture of different compounds of formula I and/or the hemimellitic acid ester of formula I comprises groups R1, R2 and R3 at least partially differing from one another.

Abstract
A tribological system, including a main body and a sandwich lubrication, wherein the sandwich lubrication includes a binder-free solid lubricant layer including a solid lubricant, and a lubricant layer including a lubricant. The binder-free solid lubricant layer and the lubricant layer are present as separate layers on the main body and the mass ratio of solid lubricant to lubricant is at most 0.05:1. The solid lubricant includes polytetrafluoroethylene (PTFE), metal sulfide, graphite, graphene, boron nitride (hexagonal), calcium phosphate, silicate, layered silicate, or mixtures thereof.

Abstract
A production method can include flowing a heterogeneous fluid mixture into contact with a homogenizing cutting tool, measuring a fluid mixture temperature so as to obtain a measured fluid mixture temperature, and determining a target fluid mixture temperature. The fluid mixture can be frictionally heated so as to obtain a heated and homogenized fluid mixture by driving the cutting tool at a rate based on (i) the target fluid mixture temperature and (ii) the measured fluid mixture temperature. The heated and homogenized fluid mixture can be flowed away from the cutting tool.
