Carbon Nanotubes. Transmission electron microscopy of carbon nanotubes: a warning.
Carbon nanotube science and technology Carbon nanotubes are molecular-scale tubes of graphitic carbon with outstanding properties. They are among the stiffest and strongest fibres known, and have remarkable electronic properties and many other unique characteristics. For these reasons they have attracted huge academic and industrial interest, with thousands of papers on nanotubes being published every year. Commercial applications have been rather slow to develop, however, primarily because of the high production costs of the best quality nanotubes. 2012 March 12 - The Scale of the Universe Interactive.
