Carbon nanotubes, called CNTs or bucky tubes (see buckminsterfullerene), are tubes of pure carbon a few nanometers in diameter and up to 2 cm long. They can be single-walled or multi-walled (tubes within tubes); electrically conducting or semiconducting; stronger than steel; tougher than Kevlar; and fireproof.
