TLDR
In this article, the amplitude of the intrinsic thermal vibrations of isolated carbon nanotubes was measured in the transmission electron microscopy (TEM) and it was shown that they have exceptionally high Young's moduli, in the terapascal (TPa) range.Abstract:
CARBON nanotubes are predicted to have interesting mechanical properties—in particular, high stiffness and axial strength—as a result of their seamless cylindrical graphitic structure1–5. Their mechanical properties have so far eluded direct measurement, however, because of the very small dimensions of nanotubes. Here we estimate the Young's modulus of isolated nanotubes by measuring, in the transmission electron microscope, the amplitude of their intrinsic thermal vibrations. We find that carbon nanotubes have exceptionally high Young's moduli, in the terapascal (TPa) range. Their high stiffness, coupled with their low density, implies that nanotubes might be useful as nanoscale fibres in strong, lightweight composite materials.read more

Large-scale synthesis of carbon nanotubes
TL;DR: In this article, the authors used a variant of the standard arc-discharge technique for fullerene synthesis under a helium atmosphere, where a carbonaceous deposit formed on one of the graphite rods, consisting of a macroscopic (diameter of about 5 mm) cylinder.

Energetics of Nanoscale Graphitic Tubules
TL;DR: It is found that the strain energy per carbon relative to an unstrained graphite sheet goes as the inverse square of the tubule radius, R, and is insensitive to other aspects of the lattice structure, indicating that relationships derivable from continuum elastic theory persist well into the small radius limit.

Growth, Structure, and Properties of Graphite Whiskers
TL;DR: Graphite whiskers have been grown in a dc arc under a pressure of 92 atmospheres of argon and at 3900°K as discussed by the authors, with recoverable lengths up to 3 cm. They are embedded in a solid matrix of graphite which builds up by diffusion of carbon vapor from the positive to the negative electrode.
