Researchers develop third and final 'made-to-order' nanotube synthesis technique

The typical 'top-down' method of producing carbon nanotubes does not allow for control over their diameter, length or which of three types will be produced. Control over two types has recently been demonstrated by producing their elementary 'nanobelt' molecules, and now researchers have developed a way to construct the third and last type, offering complete 'made-to-order' management of the synthesis of nanotube molecules.
