Scientists Radushkevich and Lukyanovich, in the Soviet Journal of Physical Chemistry publish a paper that demonstrates hollow graphitic carbon fibers that are 50 nanometers in diameter.
Scientists Hofer, Sterling and McCarney carry out experiments on tubular carbon filaments, of 10–200 nm in diameter to observe the growth rate.
Other scientists Hillert and Lange conduct experiments on nanoscale tubular carbon filaments from n-heptane decomposition on iron at about 1000 °C and observe a growth.
"Graphite whiskers" are grown by Roger Bacon in an arc-discharge apparatus which use electron microscopy to show that the structure of the 'whiskers' consist of rolled up graphene sheets in concentric cylinders.
Researches in Rice University discovered the first fullerene molecule and manufactured their own.
In June, 1991 Sumio Iijima created carbon nanotubes and named them as they have a have a tubular structure of carbon atom sheets, with a thickness scaled in less than a few nanometers.
Electron emission properties of carbon nanotubes are discovered by Swiss researchers
Researchers from Stanford University build a Carbon Nanotube Computer.
