More on oscillating nanotubes

An article in Technology Research News ("Nudged nested nanotubes may oscillate", by Eric Smalley, 6 February 2002) provides additional details on the work by researchers who calculate that a group of concentric nanotubes nested inside an outer set of tubes can slide back and forth a billion times every second, as noted here on Nanodot on 22 January 2002. Such a gigahertz oscillator could be a major advance in nanotechnology that would enable applications such as ultra-fast optical filters and nano-antennae.
