Scientists Make Blackest Material Ever

"Scientists have fashioned what may be the blackest material in the universe: a sheet of carbon nanotubes that captures nearly every last photon of every wavelength of light.

The substance absorbs between 97 percent and 99 percent of wavelengths that can be directly measured or extrapolated. It's the closest that scientists have yet come to a black body, a theorized state of perfect absorption whose closest analogue is believed to be the opening of a deep hole.

The material, described Monday by Japanese nanotechnologists in the Proceedings of the National Academy of Sciences, is made from a flat array of vertically-aligned, single-walled carbon nanotubes. Photons that aren't immediately absorbed by a single nanotube deflect off and are absorbed by its neighbors..."

Carbon Nanotube Muscles, Strong As Diamond, Flexible As Rubber

"...Turn to the laboratory of Ray Baughman, who has created a next-generation muscle from carbon nanotubes.

Baughman and his colleagues have produced a formulation that's stronger than steel, as light as air and more flexible than rubber — a truly 21st century muscle. It could be used to make artificial limbs, "smart" skins, shape-changing structures, ultra-strong robots and — in the immediate future — highly-efficient solar cells.

'We can generate about 30 times the force per unit area of natural muscle,' said Baughman, director of the NanoTech Institute at the University of Texas at Dallas...."
