The present invention is concerned with a method of generating a lubrication interface. The method has the steps of a) providing a target substrate and a growth substrate adjacent the target substrate with a confinement space defined therebetween, b) allowing a predetermined amount of water onto a surface of the target substrate in the confinement space thus forming a water layer, c) adding a predetermined amount of a sample of a molybdenum disulfides (MoS.sub.2) layer on the water layer thus allowing the water in the water layer to bind with the surface of the molybdenum disulfides (MoS.sub.2) layer, d) cooling down the target substrate to cryogenic temperature so as to freeze the water layer thus forming a molybdenum disulfides (MoS.sub.2) ice layer on the target substrate, and e) detaching the growth substrate from the molybdenum disulfides (MoS.sub.2) ice layer thus leaving the molybdenum disulfides (MoS.sub.2) ice layer.

Compositions having a plurality of hard particles and a plurality of lubricant nanoparticles are disclosed. Methods of making and using the compositions are also disclosed.
