摘要

Superlubricity occurs when friction between two sliding surfaces almost vanishes. This phenomenon has been observed so far only for small specimens that are a few micrometres wide at most. Yingying Zhang and colleagues have now observed superlubricity between centimetre-long concentric carbon nanotubes (schematically shown on the cover), which was made possible by a synthesis method that allows the production of pure carbon nanotubes that are several centimetres long.
