other tech: Radically improved thermophotovoltaics (TPV) could provide efficient power for car sub-systems

The research is applying new materials, new technologies and new ideas to radically improve an old concept — thermophotovoltaic (TPV) conversion of light into electricity. Rather than using the engine to turn a generator or alternator in a car, for example, the new TPV system would burn a little fuel to create super-bright light. Efficient …

more precise control on the way to full MNT: Researchers achieve long-sought goal of using lasers to break specific molecular bonds

Stripping hydrogen from silicon surfaces with light instead of heat promises to improve the quality of computer chips and solar cells A team of researchers has achieved a long-sought scientific goal: using laser light to break specific molecular bonds. The process uses laser light, instead of heat, to strip hydrogen atoms from silicon surfaces. This …

16 atoms of Gold have a hollow center

AU16, AU17, AU18 are the metallic equivalent of carbon 60 in that they are a metallic cage thank could hold other atoms. Scientists have uncovered a class of gold atom clusters that are the first known metallic hollow equivalents of the famous hollow carbon fullerenes known as buckyballs. The fullerene is made up of a …

Organizing dumbbells for nanotech devices

Chemist Fraser Stoddart, now at the University of California Los Angeles, and his co-workers have designed and made numerous molecules based on hanging ring-shaped molecules on other chain-like molecules and loops. By incorporating functional chemical groups along the length of the chain or around these loops, they have shown that it is possible to make …
