What it is

Cylinders of carbon atoms one nanometre in diameter with exceptional strength and conductivity. They are the benchmark material of nanotechnology.

Radushkevich and Lukyanovich (USSR, 1952) and others observed carbon filaments earlier; Iijima identified and characterised them. Merged with "Nanotubos de carbono" (duplicate, 23-09-2026).

What it led to

  • Nanotube electronics and transistors beyond silicon
  • Ultralight composite materials and improved batteries
  • The (still speculative) vision of the space elevator
  • materials nanotechnology
  • ultra-strong composites
  • nanotube electronics
  • graphene
