| Novel capability enables first test of real turbine engine conditions Posted: 16 Sep 2014 03:19 PM PDT Manufactures of turbine engines for airplanes, automobiles and electric generation plants could expedite the development of more durable, energy-efficient turbine blades thanks to a new partnership. The ability to operate turbine blades at higher temperatures improves efficiency and reduces energy costs. |
| Nanoribbon film keeps glass ice-free Posted: 16 Sep 2014 12:52 PM PDT Scientists who created a deicing film for radar domes have now refined the technology to work as a transparent coating for glass. The new work could keep glass surfaces from windshields to skyscrapers free of ice and fog while retaining their transparency to radio frequencies (RF). |
| First water-based nuclear battery can be used to generate electrical energy Posted: 16 Sep 2014 10:25 AM PDT For the first time using a water-based solution, researchers have created a long-lasting and more efficient nuclear battery that could be used for many applications such as a reliable energy source in automobiles and also in complicated applications such as space flight. |
| For electronics beyond silicon, a new contender emerges Posted: 16 Sep 2014 09:37 AM PDT Using a quantum material called a correlated oxide, researchers have achieved a reversible change in electrical resistance of eight orders of magnitude, a result the researchers are calling 'colossal.' In short, they have engineered this material to perform comparably with the best silicon switches. |
| The future face of molecular electronics Posted: 16 Sep 2014 08:17 AM PDT The emerging field of molecular electronics could take our definition of portable to the next level, enabling the construction of tiny circuits from molecular components. In these highly efficient devices, individual molecules would take on the roles currently played by comparatively bulky wires, resistors and transistors. A team of researchers has identified a potential candidate for use in small-scale electronics: a molecule called picene. |
| Making quantum dots glow brighter Posted: 16 Sep 2014 08:17 AM PDT Researchers have found a new way to control the properties of quantum dots, those tiny chunks of semiconductor material that glow different colors depending on their size. Quantum dots, which are so small they start to exhibit atom-like quantum properties, have a wide range of potential applications, from sensors, light-emitting diodes, and solar cells, to fluorescent tags for biomedical imaging and qubits in quantum computing. |
| Judging a fish by its color: For female bluefin killifish, love is a yellow mate Posted: 16 Sep 2014 07:19 AM PDT Researchers used male replicas of bluefin killifish and controlled their movement with robotic arms to improve repeatability in experiments designed to determine how fertile female fish would respond to male courtship. The surprising result: The females preferred males with yellow fins, contrary to existing research that indicated a preference to blue and red. |
| Replacing plastic and mineral wool insulation with wood fiber Posted: 16 Sep 2014 05:48 AM PDT Researchers are developing wood fiber-based insulation materials and sprayable insulation foams with enhanced product features. The new materials will enable mass production of high-quality insulation products, which will replace products made of non-renewable or poorly recyclable raw materials. Use of wood-based material will lower energy consumption at the production stage, as well as reducing the products' carbon footprint. |
