CARBON NANOTUBES INCLUDE A REMARKABLY versatile set of molecules, which possess extraordinary strength, flexibility, and thermal conductivity, as well as many novel electronic characteristics. Depending on the specific arrangement of its constituent atoms, a nanotube can be a conductor or semiconductor, and a miniature wire, a diode, or a transistor. Some types of nanotubes generate orders of magnitude less heat than comparable copper wires when a current is passed through them. With all of these useful electrical and mechanical properties, nanotubes also have only one-sixth the density of steel....
