Carbon are not the only nanotubes - Materials Today
Researchers in France and the US have demonstrated that although multiwalled carbon nanotubes (CNTs) and boron nitride nanotubes (BNNTs) are very similar in structure and properties, there is one critical property in which they differ significantly - friction.Lydéric Bocquet, a visiting professor at MIT, and a team led by Alessandro Siria at Université de Lyon in France, have found that while CNTs are so slippery that they have a characteristic known as superlubricity, which makes them essentially frictionless materials, BNNTs are the exact opposite, they display a very high level of friction.
