Certain citric esters and amides, and certain mixtures thereof, e.g., mixtures comprising citrate oligomers, exhibit excellent anti-wear activity in lubricants. Many of these compounds or mixtures of compounds also exhibit a high degree of anti-wear synergy in combination with zinc dihydrocarbyldithiophosphates. The compounds of the invention are thus valuable tools that can allow one to reduce the amounts of zinc, and phosphates, that are used in the lubricant without sacrificing anti-wear performance.

Anti-wear composition for lubricants

A non-aqueous flow cell energy storage device comprises a ionically conductive separator, which separator comprises a polyurethane prepared by curing an isocyanate capped prepolymer, which prepolymer was prepared from a polyol having polycarbonate backbone, wherein the separator may be impregnated with electrolyte salts and/or swelled by an organic solvent.
