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.
