Superlubricity (or the almost absence of all friction) exists in centimetre-long double-walled carbon nanotubes, according to new experiments by researchers at Tsinghua and Peking universities in China. The finding, which proves once again that the phenomenon can appear on length scales much larger than previously thought, might help make improved micro- and nanodevices based on nanotubes in the future that do not suffer from friction……..
