Making Nanotubes Takes Lots of Heat and Patience

To start forming nanotubes takes two carbon graphite electrodes and DC generator. Electricity produces magnetic field and tremendous heat in the atmosphere of inert gas, such as helium, in order to avoid oxidation of graphite.  At about four thousand degrees the atoms of carbon, torn from one electrode get deposited on the end of another electrode forming nanotubes. What is also worth noting, heat along is not sufficient for the nanotubes to start being formed. It is the electron flow from one tip to another that creates virtual pipeline for the carbon atoms to be transferred and placed in precise hexagon position. The presence of electric field and its shape dictates the structure of newly formed nanotubes. No wonder nanotubes are often very good conductors of electricity.
