| Commonalities in how different glassy materials fail Posted: 09 Dec 2014 09:03 AM PST Researchers have now shown an important commonality that seems to extend through the range of glassy materials. They have demonstrated that the scaling between a glassy material's stiffness and strength remains unchanged, implying a constant critical strain that these materials can withstand before catastrophic failure, despite the extreme variation found among this class of material's physical properties.  |
| Germanium: Semiconductor milestone Posted: 09 Dec 2014 09:03 AM PST A laboratory at Purdue University provided a critical part of the world's first transistor in 1947 -- the purified germanium semiconductor -- and now researchers there are on the forefront of a new germanium milestone. The team has created the first modern germanium circuit -- a complementary metal-oxide-semiconductor (CMOS) device -- using germanium as the semiconductor instead of silicon.  |
| The gold standard: Affordable catalyst for energy and environmental applications Posted: 09 Dec 2014 09:03 AM PST New nanoscale computational modeling predicts gold could be an effective and affordable catalyst for energy and environmental applications.  |
| Composite materials can be designed in a supercomputer 'virtual lab' Posted: 09 Dec 2014 05:18 AM PST Scientists have shown how advanced computer simulations can be used to design new composite materials. Nanocomposites, which are widely used in industry, are revolutionary materials in which microscopic particles are dispersed through plastics. But their development until now has been largely by trial and error.  |
| Using robots to get more food from raw materials Posted: 09 Dec 2014 05:16 AM PST Can an industrial robot succeed both at removing the breast fillet from a chicken, and at the same time get more out of the raw materials? Researchers have now built a fully-functional robot in the lab to automate the process of extracting breast fillets from chickens. This is a task normally performed by skilled human hands.  |
| Major milestone in development of interband cascade lasers Posted: 09 Dec 2014 05:10 AM PST Scientists have reached a major milestone in the development of interband cascade lasers by creating a robust technology that operates at room temperature and works continuously -- an important component for building practical systems.  |
