| Researchers develop AFM-IR for nanometer scale chemical identification Posted: 08 Mar 2013 03:38 PM PST Researchers report that they have measured the chemical properties of polymer nanostructures as small as 15 nm, using a novel technique called atomic force microscope infrared spectroscopy.  |
| Quantum refrigerator offers extreme cooling and convenience Posted: 08 Mar 2013 03:38 PM PST Researchers have demonstrated a solid-state refrigerator that uses quantum physics in micro- and nanostructures to cool a much larger object to extremely low temperatures. What's more, the prototype refrigerator, which measures a few inches in outer dimensions, enables researchers to place any suitable object in the cooling zone and later remove and replace it, similar to an all-purpose kitchen refrigerator.  |
| Posted: 07 Mar 2013 09:47 AM PST Researchers have found that some widely used formulas for predicting how rapidly technology will advance -- notably, Moore's Law and Wright's Law -- offer superior approximations of the pace of technological progress. The new research is the first to directly compare the different approaches in a quantitative way, using an extensive database of past performance from many different industries.  |
| Hurdle overcome in development of terahertz lasers Posted: 07 Mar 2013 09:46 AM PST Scientists have developed a device that is critical to the use of terahertz sources for a variety of applications. Their electromagnetic non-reciprocal isolator paves the way for applications using terahertz frequencies including the development of terahertz lasers and amplifiers, to which the scientific community is currently devoting much attention.  |
| Waves generated by Russian meteor recorded crossing the US Posted: 07 Mar 2013 09:45 AM PST A network of seismographic stations recorded spectacular signals from the blast waves of the meteor that landed near Chelyabinsk, Russia, as the waves crossed the United States.  |
