Carbon nanotube. Computer artwork of a carbon nanotube,also known as a buckytube,showing the hexagonal carbon structure. Atoms are represented as spheres and the bonds between them by rods. Nanotubes are a type of fullerene molecule,a structural form (allotrope) of carbon,whose atoms are arranged into interlinking hexagonal and pentagonal rings. Theoretically,a wide range of shapes can be engineered at the molecular level using fullerenes. Such structures could have a wide range of uses in nanotechnology |
