| Blades of grass inspire advance in organic solar cells Posted: 30 Sep 2014 11:42 AM PDT Using a bio-mimicking analog of one of nature's most efficient light-harvesting structures, blades of grass, an international research team has taken a major step in developing long-sought polymer architecture to boost power-conversion efficiency of light to electricity for use in electronic devices. |
| New dimension for integrated circuits: 3-D nanomagnetic logic Posted: 30 Sep 2014 11:42 AM PDT Electrical engineers have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on three-dimensional arrangements of nanometer-scale magnets instead of transistors. As CMOS, the main enabling technology of the semiconductor industry, approaches fundamental limits, researchers are exploring 'magnetic computing' as an alternative. |
| Novel method for making electrical cellulose fibers Posted: 30 Sep 2014 11:34 AM PDT By using liquid salts during formation instead of harsh chemicals, fibers that conduct electricity can be strengthened, according to new research. |
| A heartbeat away? Hybrid 'patch' could replace transplants Posted: 30 Sep 2014 08:34 AM PDT Because heart cells cannot multiply and cardiac muscles contain few stem cells, heart tissue is unable to repair itself after a heart attack. Now researchers are literally setting a new gold standard in cardiac tissue engineering, using gold particles to increase the conductivity of biomaterials. |
| How to make a 'perfect' solar absorber Posted: 30 Sep 2014 08:32 AM PDT Researchers have developed a solar cell that can tap the sun's full radiation spectrum. The material is a two-dimensional metallic dielectric photonic crystal, and has the additional benefits of absorbing sunlight from a wide range of angles and withstanding extremely high temperatures. Perhaps most importantly, the material can also be made cheaply at large scales. |
| Fuel cell-powered mobile lights tested, proven, ready for commercial use Posted: 30 Sep 2014 08:16 AM PDT Mobile lighting systems powered by hydrogen fuel cells are cleaner, quieter and now have a proven track record in applications such as nighttime construction, sports and entertainment events and airport operations, making them ready for commercialization and broader use, developers say. |
| Posted: 29 Sep 2014 12:39 PM PDT Researchers have combined computer simulations designed for Hollywood with precision model experiments to examine the mechanics of coiling. Their study, which bridges engineering mechanics and computer graphics, impacts a variety of engineering applications, from the fabrication of nanotube serpentines to the laying of submarine cables and pipelines. |
