| Cheap, better-performing lithium-ion batteries created Posted: 31 Mar 2014 11:41 AM PDT Researchers have developed a cheap, high-performing silicon anode and sulfur-based cathode for lithium-ion batteries. Lithium-ion batteries are a popular type of rechargeable battery commonly found in portable electronics and electric or hybrid cars. Scientists have developed a cost-effective (and therefore commercially viable) silicon anode nearly three times more powerful and longer lasting than a typical commercial anode.  |
| Hybrid vehicles more fuel efficient in India, China than in U.S. Posted: 31 Mar 2014 11:41 AM PDT What makes cities in India and China so frustrating to drive in -- heavy traffic, aggressive driving style, few freeways -- makes them ideal for saving fuel with hybrid vehicles, according to new research. In a pair of studies using real-world driving conditions, they found that hybrid cars are significantly more fuel-efficient in India and China than they are in the United States.  |
| Information processing demonstrated using a light-based chip inspired by our brain Posted: 28 Mar 2014 02:51 PM PDT Researchers report on a novel paradigm to do optical information processing on a chip, using techniques inspired by the way our brain works. Neural networks have been employed in the past to solve pattern recognition problems like speech recognition or image recognition, but so far, these bio-inspired techniques have been implemented mostly in software on a traditional computer. What researchers have now done is implement a small (16 nodes) neural network directly in hardware, using a silicon photonics chip.  |
