carbon nanotube….. The nanotube is a molecular cousin of a form of carbon that is perhaps more familiar, the C60 molecule or buckyball, an array of 60 carbon atoms forming a soccer-ball-like icosahedron. If the buckyball could be sliced in half, with a “belt” made of a connected loop of 10 carbon atoms inserted in the cut, it would form another stable configuration, a C70 molecule that is a larger and somewhat elongated buckyball. If instead one inserted two or three 10-carbon loops, this would make even more elongated C80 or C90. The process could be repeated to produce an arbitrarily long tube, with endcaps made of half-buckyball hemispheres. The object thereby produced is a species of carbon nanotube.

o apparently there is some case being made that there are carbon nano tubes in the damascene steel… interesting

w00t(z)!

Its Tippu Sultan’s sword, made of wootz steel.
The rediscovered “miracle material” is carbon nanotubes.

Damascus swords — sharp enough to slice a falling piece of silk in half, strong enough to split stones without dulling — owe their legendary qualities to carbon nanotubes, says chemist and Nobel laureate Robert Curl.

The blades used so-called wootz steel, smelted with a technique developed 2000 years ago in India, where craftsmen added wood and other organic debris to their furnaces. The resulting carbon-laced steel, hard but flexible, was soon celebrated across the ancient world.

The sword of Tipu Sultan.
The miracle material is Carbon Nanotubes. It was a part of the Damascus steel with which the sword is made up of.Carbon nanotubes which are cylidrical fullerenes have extraordinary strength in terms of tensile strength and elastic modulus.

The sword of Tipu Sultan.
It contained carbon nanotubes ( “miracle material”)- part of the Damascus steel body of the sword.Carbon nanotubes are cylidrical fullerenes which have extraordinary strength in terms of tensile strength and elastic modulus.
