What are Nanotubes

• Seamless cylindrical shells of graphitic
  carbon which have novel mechanical and electronic
  properties that suggest new high strength fibers,
  submicroscopic test tubes, and perhaps, new
  semiconductor materials..Thomas W. Ebbesen

History

• The discovery of multi-wall carbon nanotubes was
  in 1991.
• Hydrogen storage in nanotubes in 1997

• The single-wall nanotubes were discovered in 1993
• Synthesis of nanotube peapods in 1998

Technology

• The JSC Carbon Nanotube Project is focused on
  developing bulk nanotube production, purification
  and application of Single-Wall Carbon Nanotubes
  (SWNT's).
• The goal for their project is to develop nanotube
  applications for use in human space exploration. 
  
• Carbon Nanotubes will be useful for miniaturized
  electronic, mechanical, electromechanical,
  chemical and for scanning probe nano-devices, and
  materials for microscopic composites.

• Carbon Nanotubes can be metallic or
  semiconducting and offers amazing possibilities
  to create future nanoelectronic devices,
  circuits, and computers.
