Nanotubes used as nanotools

Experiments on nanoubes have revealed they could be used as tools to squeeze extremely hard materials such as iron and iron carbide. Such discovery will allow scientists to perform high pressures operations as the nanotubes “withstood pressures as high as 40 gigapascals, just an order of magnitude below the roughly 350 gigapascals of pressure at the center of the Earth.” Nanotubes tool
Bombarding a carbon nanotube with electrons causes it to collapse with such incredible force that it can squeeze out even the hardest of materials, much like a tube of toothpaste, according to an international team of scientists. Reporting in the May 26 issue of the journal Science, the researchers suggest that carbon nanotubes can act as minuscule metalworking tools, offering the ability to process materials as in a nanoscale jig or extruder.
