Inorganic fullerene‐like nested nanostructures (IFs) such as the WS 2 IFs shown in the Figure deposited on an a‐SiO x ‐coated TEM grid are confirmed to confer tribological advantages when added to a lubricant fluid (tetradecane) between two shearing mica surfaces. It is shown that the lower friction is associated with friction‐induced material transfer of WS 2 from the IFs to the mica surfaces.
