Carbon nanotubes and their recent developments

In his book published in 1985 Drexler proposed a molecular bearing consisting of two graphitic nanotubes of different diameter which are concentrically arranged (1992). It was a virtual operation inside a computer. This dream, however, has become more realistic by the discovery of carbon nanotubes by the author (1991). The discovery, unique atomic structures, production, growth, expected properties and some experiments on carbon nanotubes are reviewed.
