| ASU scientists improve chip memory by stacking cells | | Scientists at Arizona State University have developed an elegant method for significantly improving the memory capacity of electronic chips. | | Leer la noticia completa | 25 de Jan de 2010 - 11:33 AM | |
| Revolutionary microchip uses 30 times less power | | In the first real-world test of a revolutionary type of computing that thrives on random errors, scientists have created a microchip that uses 30 times less electricity while running seven times faster than today's best technology. The U.S.-Singapore team developing the technology, dubbed PCMOS [pronounced "pee-cee-moss"], revealed the results here today at the International Solid-State Circuits Conference (ISSCC), the world's premier forum for engineers working at the cutting edge of integrated-circuit design. | | Leer la noticia completa | 27 de Mar de 2009 - 10:03 AM | |
| NanoCenter Improves Energy Storage Options | In order to save money and energy, many people are purchasing hybrid electric cars or installing solar panels on the roofs of their homes. But both have a problem—the technology to store the electrical power and energy is inadequate. Battery systems that fit in cars don't hold enough energy for driving distances, yet take hours to recharge and don't give much power for acceleration. Renewable sources like solar and wind deliver significant power only part time, but devices to store their energy are expensive and too inefficient to deliver enough power for surge demand. | | Leer la noticia completa | 24 de Mar de 2009 - 02:39 PM | |
| University Of Miami Physicist Develops Battery Using New Source Of Energy | | Researchers at the University of Miami and at the Universities of Tokyo and Tohoku, Japan, have been able to prove the existence of a “spin battery,” a battery that is "charged" by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction (MTJ). The new technology is a step towards the creation of computer hard drives with no moving parts, which would be much faster, less expensive and use less energy than current ones. In the future, the new battery could be developed to power cars. The study will be published in an upcoming issue of Nature and is available in an online advance publication of the journal. | | Leer la noticia completa | 14 de Mar de 2009 - 09:27 PM | |
