carbon nanotubes [‚kär·bən ′nan·ō‚tübz] (chemistry) Cylindrical molecules (sealed at both ends with a convex arrangement of atoms) composed of carbon with a diameter of around 1 nanometer and lengths up to a few micrometers. Single-walled nanotubes may be conducting or semiconducting, depending on the diameter and chirality of the tube. Multiwall nanotubes containing coaxial shells of the elemental single-wall nanotubes are also possible. How to thank TFD for its existence?

Although carbon nanotubes usually clump in water, they readily disperse when the water contains natural organic matter, researchers report. We are currently in negotiations with a number of entities worldwide who require a license from us under our patent rights, and we will continue to grant licenses to such entities, from venture companies to multinational corporations, with reasonable terms and conditions, in order to expand the markets of carbon nanotubes and their applications. AIST has encapsulated beta-carotene in HiPco single-walled carbon nanotubes (SWCNTs), a type of carbon nanotube currently marketed by Carbon Nanotechnologies Inc. |
