A long cylindrical structure related to the fullerenes. The structure of these rods appears to be a stacked graphite ring structure on the outside, and a randomized graphitic crystal structure on the inside. Generally, these tubes form best at temperatures above 1200° C, and not at all under 200° C.Found on http://www.chemistry-dictionary.com/definition/nanotube.php

nanotube A hollow cylindrical or toroidal molecule made of one element, usually carbon. Nanotubes are being investigated as semiconductors and for uses in nanotechnology. A toroid is defined as a surface generated by rotating a closed curve around an axis that is in the same plane as the curve but does not intersect it.Found on http://www.wordinfo.info/words/index/info/view_unit/3880/
