What are pristine nanotube?

tubes that are small

nanotube. A nanotube is a nanometer scale wire-like structure that is most often composed of carbon: carbon nanotube Inorganic nanotubes have also been synthesised, including: boron nitride...

Yeah probably because when scientists found that a paper-thin sheet of this wonder material can crack open a bullet they start making ideas to make military armors made of carbon nanotube so that...

Nanotubes are made fom carbon, metals, oxides, other inorgaqnic compounds; the living beings contain also some natural nanotubes.

Most nanotubes' diameters are around 1 nanometer. Nano means one billionth (1/1,000,000,000).
