GE Develops High Performance Carbon Nanotube Diode - SpaceDaily  Unlike traditional diodes, GE's carbon nanotube device has the ability for multiple functions - as a diode and two different types of transistors - which should enable it to both emit and detect light. GE's breakthrough device comes very close to the theoretical limits of performance. Measured through the ideal diode equation, developed by Nobel Laureate William Shockley, GE's new diode has an "ideality factor" very close to one, which is the best possible performance for a diode. One possible application for GE is to use the device to build the next generation of advanced sensors.
Climate Searching For The 'Dread Factor' - SpaceDaily  At first, the dread factor is CO2 doubling, Glantz told United Press International. That didn't catch on, so they went to the West Antarctic ice sheet collapse. Then three degrees (Celsius) increase in (global temperature in) a hundred years. Most people don't know what C is. If you live in Minnesota, it sounds OK -- until you find out that you can't go cross country skiing. The dread list continues, Glantz said. They came up with thermohaline circulation breakdown. Then abrupt climate change on the order of decades. They keep trying to get the hook in. The fear of skin cancer got action on ozone depletion, Glantz said.

Carbon nanotube fibre after spinning

Nano-team spins tomorrow's yarn  - BBC   The result is an extremely fine and strange black thread that is about as strong as clothes fibre, and can carry an electrical current. Professor Windle and his team aim to improve that strength 10-fold in the next year or so, but they need to learn more about how to organise the nanotubes before strength can be improved. They could potentially prove to be stronger than steel. In theory, Professor Windle explained, a satellite could be "tied" to Earth with a cable, but it has to be light and very strong, hence the excitement around carbon nanotubes. "We have 10 years of very exciting material science here,"
