Inside a carbon nanotube
1952
  • Radushkevich and Lukyanovich publish a paper in the Russian Journal of Physical Chemistry showing hollow graphitic carbon fibers that are 50 nanometers in diameter.[1]
1976
  • Oberlin, Endo and Koyama report CVD growth of nanometer-scale carbon fibers.[2]
1979
1985
1987
  • Howard G. Tennent of Hyperion Catalysis issued a U.S. patent for graphitic, hollow core "fibrils".[5]
1991
  • Nanotubes discovered in the soot of arc discharge at NEC, by Japanese researcher Sumio Iijima.[6]
  • August — Nanotubes discovered in CVD by Al Harrington and Tom Maganas of Maganas Industries, leading to development of a method to synthesize monomolecular thin film nanotube coatings.[7]
1993
  • Groups led by Donald S. Bethune at IBM[8] and Sumio Iijima at NEC[9] independently discover single-wall carbon nanotubes and methods to produce them using transition-metal catalysts.
2001
  • April — IBM announces a technique for automatically developing pure semiconductor surfaces from nanotubes.[10]
2002
  • January — Multi-walled nanotubes demonstrated to be fastest known oscillators (> 50 GHz).[11]
  • REBO method of quickly and accurately modeling classical nanotube behavior is described.[12]
2003
  • April — Demonstration proves that bending changes resistance.[13]
  • June — High purity (20% impure) nanotubes with metallic properties were reported to be extracted with electrophoretic techniques.[14]
  • September — NEC announced stable fabrication technology of carbon nanotube transistors[15]
2004
2005
  • May — A prototype high-definition 10-centimetre flat screen made using nanotubes was exhibited.[19]
  • August — University of California finds Y-shaped nanotubes to be ready-made transistors.[20]
  • August — General Electric announced the development of an ideal carbon nanotube diode that operates at the "theoretical limit" (the best possible performance). A photovoltaic effect was also observed in the nanotube diode device that could lead to breakthroughs in solar cells, making them more efficient and thus more economically viable.[21]
  • August — Nanotube sheet synthesised with dimensions 5 × 100 cm.[22]
  • September — Applied Nanotech (Texas), in conjunction with six Japanese electronics firms, have created a prototype of a 25-inch TV using carbon nanotubes. The prototype TV does not suffer from "ghosting," as some types of digital TVs do.[23]
  • September — Researchers at Lawrence Livermore National Laboratory demonstrated that ignition by a conventional flashbulb takes place when a layer of 29% iron enriched SWNT is placed on top of a layer of explosive material such as PETN. With ordinary explosives optical ignition is only possible with high powered lasers.[24]
  • September — Researchers demonstrated a new way to coat MWNT's with magnetite which after orientation in a magnetic field were able to attract each other over a distance of at least 10 micrometres.[25]The nanotubes were functionalized with negatively charged carboxylic acid groups in an AIBN type free radical addition. Magnetite nanoparticles prepared by the Massart method were given a positive charge by washing with nitric acid which made them stick to the nanotubes by electrostatic forces.
  • September — American and Korean scientists, working at Columbia University and Pohang University of Science and Technology and lead by Professor's Philip Kim of Columbia and Kim Kwang-Soo of Pohang, succeeded in pulling out a nested tube from a multiwalled nanotube (MWNT).[26]

  • March — IBM announces that they have built an electronic circuit around a CNT.[32]
  • March — Nanotubes used as a scaffold for damaged nerve regeneration.[33]
  • May — Method of placing nanotube accurately is developed by IBM.[34]
