Abstract
With the help of a two- dimensional ( 2D) model we study rolling lubrication by circular (` 2D fullerenes') molecules for a wide range of parameters. The conditions under which microscopic rolling friction may be effective are identified and related to the relative ingraining between substrate and molecule, the latter behaving as a nanosized cogwheel.File in questo prodotto:
