Molecular bearings of finite carbon nanotubes and fullerenes in ensemble rolling motion

A carbonaceous bearing of a minimal form has been assembled using a finite carbon nanotube molecule and a functionalised fullerene molecule. With the van der Waals attraction, the bearing holds the fullerene journal tightly to prevent its run-out motion, and the journal with a shaft rolls anisotropi...

Description
Summary:A carbonaceous bearing of a minimal form has been assembled using a finite carbon nanotube molecule and a functionalised fullerene molecule. With the van der Waals attraction, the bearing holds the fullerene journal tightly to prevent its run-out motion, and the journal with a shaft rolls anisotropically in the bearing despite the tight holding constraint. Ensemble motion has been revealed spectroscopically at the molar quantity level. Ensemble rolling motion in a bearing made from a carbon nanotube molecule and a functionalized fullerene molecule has been demonstrated.
