Nanotech Advance Makes Carbon Nanotubes More Useful - SpaceDaily  Left: UCSD researchers exploited the strong alignment of nanotube growth with the direction of electric field lines to create tailor-made bends. Researchers at UCSD have made carbon nanotubes bent in sharp predetermined angles, a technical advance that could lead to use of the long, thin cylinders of carbon as tiny springs, tips for atomic force microscopes, smaller electrical connectors in integrated circuits, and in many other nanotechnology applications. "Controlling nanotube geometry is necessary to realize the many promised applications of these materials," said Jin, a professor in the Jacobs School's Department of Mechanical and Aerospace Engineering. "Our new results show that we have taken a step toward understanding how to shape nanotubes to our specifications, an achievement that could greatly enhance their value to society."   
Climate: The Oceanic CO2 Puzzle - SpaceDaily  For years, climate scientists and oceanographers have been struggling to figure out the relationship of carbon dioxide in the oceans to the amount of CO2 in the atmosphere. There is a definite connection, but to date no one has been able to discover what it is. The only thing for sure is concentrations of atmospheric carbon dioxide have fluctuated naturally by about 80 to 100 parts per million between glacial and interglacial periods during Earth's recent geological history. "The overall conclusion is that CO2 has changed in the past, and at glacial periods it was roughly 30 to 35 percent lower than it was in pre-industrial times. This has occurred consistently over glacial periods, at least for the last 800,000 years," Kohfeld said. "Every 100,000 years, we have these time periods where CO2 drops. It drops for natural reasons."

Molecular Breakthrough For Plastic Electronics - SpaceDaily  The potential applications for flexible plastic electronics are enormous - from electronic books to radio frequency identification (RFID) tags to electronics for cell phones, PDAs and laptop computers - but certain technological hurdles must be overcome before we see such widespread use. Now a Northwestern University team of materials chemists report a breakthrough in the race to find the right materials for producing cost-effective, high-performance plastic electronics. Their tailored molecular components reduce both operating voltage and power consumption in organic thin-film transistor (OTFT) structures, making low-power consumption OTFTs a reality.
