Nanotube yarn 30 cm long
(in China): "A Chinese research team have found new approaches to pull carbon nanotubes into continuous yarns up to 30 centimetres long .. Another interesting finding is the conductivity and strength of the yarns can be enhanced by heating them at high temperatures. " 11:47:57 PM
It Slices! It Dices! Nanotube Struts Its Stuff
: Nice NYT review of nanotech developments. My favorite: "the world's smallest working gears. He mixed nanotubes into molten nylon and then squirted the nylon into a tiny mold. Instead of the outer skin cooling first, the heat-diffusing property of nanotubes kept the nylon uniformly molten as it filled every nook and cranny of the mold. That produced a finely chiseled gear about as wide as a human hair. The nanotubes also give it strength. Coincidentally, they also conduct electricity, a superfluous capability for a gear. Sometimes some of nanotubes' amazing properties are more than needed." 9:04:10 PM
