Abstract
An improved method of synthesizing nanotubes that avoids the slow process and the impurities or defects that are usually encountered with regard to as-grown carbon nanotubes. In a preferred embodiment, nanotubes are synthesized from nanotubes providing a novel catalyst-free growth method for direct growth of single- or multi-walled, metallic or semiconducting nanotubes.
