Nanoyarn

Carbon nanotubes at the entrance to the show in 1991, visionaries and futurists have one day. The structure, heat, electricity, and this feature cylindrical molecules of carbon, which is, in theory, they can be used to build a strong structure of the unusual, like the space elevator, which is 62,000 miles Earth, or exceptional, compact and fast digital computers. In practice, however, is difficult to mass-produce nanotubes are long enough for engineers to do something extraordinary. Now NANOCOMP Technologies, headquartered in Concord, New Hampshire, tried to order the immediate future of the manufacturer, in bulk, and son of films of carbon nanotubes.

At the atomic scale, such as carbon nanotubes, rolled-up tube of chicken wire, and not just metal, the tube is made of hexagonal lattice of carbon atoms. Each tube is about one nanometer (billionth of a meter) in diameter, then the name. Today, the nanotubes are generally in a segment about 10,000 nanometers in length, black powder. This powder is only a small fraction of the properties of nanotubes. NANOCOMP said he could TEN nanotubes to a hundred times, the son of training and sheets of carbon (up to one kilometer length of wire, the best tensile strength of steel, and scores in the 18-square feet).
