| Electrical engineers build 'no-waste' laser Posted: 09 Feb 2012 02:33 PM PST Researchers have built the smallest room-temperature nanolaser to date, as well as an even more startling device: a highly efficient, "thresholdless" laser that funnels all its photons into lasing, without any waste.  |
| 'Dark plasmons' transmit energy Posted: 09 Feb 2012 02:29 PM PST Microscopic channels of gold nanoparticles have the ability to transmit electromagnetic energy that starts as light and propagates via "dark plasmons," according to researchers.  |
| Hydrogen from acidic water: Potential low cost alternative to platinum for splitting water Posted: 09 Feb 2012 12:28 PM PST A technique for creating a new molecule that structurally and chemically replicates the active part of the molybdenite catalyst paves the way for developing catalytic materials that can serve as effective low-cost alternatives to platinum for generating hydrogen gas from water.  |
| Seismic resistance: Model analyzes shape-memory alloys for use in earthquake-resistant structures Posted: 09 Feb 2012 10:58 AM PST Recent earthquake damage has exposed the vulnerability of existing structures to strong ground movement. Researchers are now analyzing shape-memory alloys for their potential use in constructing seismic-resistant structures.  |
| New battery could lead to cheaper, more efficient solar energy Posted: 09 Feb 2012 10:58 AM PST Scientists have found that a new type of battery has the potential to improve the efficiency and reduce the cost of solar power.  |
| Nanotube therapy takes aim at breast cancer stem cells Posted: 09 Feb 2012 10:14 AM PST Researchers have again shown that injecting multiwalled carbon nanotubes (MWCNTs) into tumors and heating them with a quick, 30-second laser treatment can kill them.  |
| Piranha vs. Arapaima: Engineers find inspiration for new materials in piranha-proof armor Posted: 09 Feb 2012 07:18 AM PST It's a matchup worthy of a late-night cable movie: put a school of starving piranha and a 300-pound fish together, and who comes out the winner? The surprising answer -- given the notorious guillotine-like bite of the piranha -- is Brazil's massive Arapaima fish. The secret to Arapaima's success lie in its intricately designed scales, which could provide "bioinspiration" for engineers looking to develop flexible ceramics.  |
| Posted: 08 Feb 2012 10:23 AM PST At the high-brilliance synchrotron light source PETRA III, scientists have succeeded in making atomic nuclei transparent with the help of X-ray light. At the same time they have also discovered a new way to realize an optically controlled light switch that can be used to manipulate light with light, an important ingredient for efficient future quantum computers.  |
