Quote of the day

According to Tom Theis, IBM's director of physical sciences, "Nanotubes with diameters of only 1.5 to 2 nanometers possess many times the strength of steel and conduct electricity as both a metal and a semiconductor." Because of these properties, Theis says, "I can't imagine a more aggressive transistor technology right now."

In the chip-making world of the future, microprocessor makers will likely use carbon nanotubes instead of transistors to make chips smaller and more powerful.

"There's a lot of work going on in carbon nanotubes and some other exotic devices which may be the next technology that takes us to new levels of speed and performance."

~Ned Barnholt, Agilent Technologies CEO

"The future is bright for nanotechnology. Nanoscale processes like General Motors' quick-plastic-forming aluminum are simplifying supply chains. Nanoparticulate diagnostics from companies like Nanosphere can turn fatal diseases into livable conditions. And nanoelectronics innovations from carbon nanotube electronics to spintronics promise to keep Moore's law going for another 30 years."

Nanotubes have gone into warp drive. Baughman's team can churn out up to ten metres of nanoribbon every minute, as easily as pulling a strip of sticky tape from a reel. This ribbon can be up to five centimetres wide, and after a simple wash in ethanol compacts to just 50 nanometres thick, making it 2,000 times thinner than a piece of paper. The ribbons are transparent, flexible, and conduct electricity. Weight for weight, they are stronger than steel sheets, yet a square kilometre of the material would weigh only 30 kilograms. "This is basically a new material," says Ray Baughman (Director of the NanoTech Institute of the University of Texas at Dallas). http://www.nature.com/news/2005/050815/full/050815-8.html
