Surfactant‐coated nanorods , rather than bare spheres, can provide both low friction and good surface wear protection (see figure) when used as additives in fluids that are not good lubricants on their own. A combination of nanoparticle geometry, nanoparticle forces, and dynamic properties appears to be responsible for the improved lubrication.
