It was known that diamonds are already one of the hardest natural substances. But if diamoınd combine with graphene, nanoparticles can be slippery and it can be useful if you want to reduce friction in a moving machine. Scientist showed that the combination of tiny bits of diamond and graphene that had superlubricity. This means that the friction between them and another object dropped to near zero.
Reducing friction, or making things more slippery could have benefits beyond just making it easier for objects to move around. For example "nearly one-third of a vehicle's fuel energy is spent on overcoming engine, transmission, and tire friction." Reduce the friction, reduce the amount of fuel used.
Diamond nanoparticles contact with the thin sheets of graphene and the graphene rolled up around the diamond nanoparticles, creating scroll or ball like structures. This specific structure makes the superlubricity possible right now, but researchers hope that they can expand the property to other materials in the future.
Scientist stated that the knowledge gained from this study will be important in finding ways to reduce friction in everything from engines or turbines to computer hard disks and microelectromechanical systems.
