C60 Fullerene has a special spherical configuration, and is the best round of all the molecules. Because of the structure, all molecules of C60 have special stability, while a single C60 molecule is extremely hard at the molecular level, which makes C60 possibly as core material of lubricant; C60 is so hopefully to translate into a new abrasive material with high hardness as a result of C60 molecules’ special shape and strong ability to resist external pressures.
