Phys. Rev. Lett. 96, 186104 (2006) [4 pages]C60 Molecular Bearings and the Phenomenon of NanomappingReceived 2 January 2006; published 11 May 2006 Inspired by suggestions of C60 “nanobearings,” we have measured sliding friction on fixed and rotating C60 layers to explore whether a lubricating effect is present. We refer to this general phenomenon as “nanomapping,” whereby macroscopic attributes are mapped in a one on one fashion to nanoscale entities. Our measurements are the first to directly link friction to a documented molecular rotation state. Friction is, however, observed to be higher for rotating layers, in defiance of the ball-bearing analogy. Thus, no direct mapping of macro- to nanoscale attributes can be established. © 2006 The American Physical Society URL:
