A grease composition is disclosed which is intended primarily for use in constant velocity joints (CV joints), especially ball joints and/or tripod joints, which are used in the driveline of motor vehicles. The grease composition for use in constant velocity joints comprises at least one base oil, at least one thickener, zinc sulfide, at least one copper sulfide and molybdenum disulfide and/or tungsten disulfide. Further, the present disclosure relates to a constant velocity joint comprising such a grease composition.

A method of upcycling polymers to useful hydrocarbon materials. A catalyst with nanoparticles on a substrate selectively docks and cleaves longer hydrocarbon chains over shorter hydrocarbon chains. The nanoparticles exhibit an edge to facet ratio to provide for more interactions with the facets.

The present invention provides a grease composition to be used for lubrication between resin-made members or lubrication between a resin-made member and a member made from another material. With respect to the total mass of the composition, more than 0.5 mass % but less than 7.5 mass% of a solid organic molybdenum compound is contained.
