Toward lowering titanium's cost and environmental footprint for lightweight products Washington DC (SPX) Dec 22, 2013 - A novel method for extracting titanium, a metal highly valued for its light weight, high strength, corrosion resistance and biocompatibility, could lower its cost and make it more widely accessible, for example, for producing lighter car parts to improve fuel efficiency. The method, which significantly reduces the energy required to separate it from its tightly bound companion, oxygen, app ... more |  |
 Roots of the Lithium Battery Problem Berkeley CA (SPX) Dec 22, 2013 - The lithium-ion batteries that power our laptops, smartphones and electric vehicles could have significantly higher energy density if their graphite anodes were to be replaced by lithium metal anodes. Hampering this change, however, has been the so-called dendrite problem. Over the course of several battery charge/discharge cycles, particularly when the battery is cycled at a fast rate, mi ... more |  |
 Sharpening the focus in quantum photolithography Heidelberg, Germany (SPX) Dec 22, 2013 - Photolithography uses light beams to design thin geometric patterns on the substrates of semiconductors used in microelectronic devices. This is achieved using a chemical reaction on a light-sensitive chemical, called photoresist. The trouble is that the phenomenon of light diffraction does not permit highly accurate patterns. Often, the edges of stripes have low contrast, and the distances betw ... more |  |
 UNIST research team opens graphene band-gap Ulsan, South Korea (SPX) Dec 22, 2013 - Ulsan National Institute of Science and Technology (UNIST) announced a method for the mass production of boron/nitrogen co-doped graphene nanoplatelets, which led to the fabrication of a graphene-based field -effect transistor (FET) with semiconducting nature.

Theorists Predict New State of Quantum Matter May Have Big Impact on Electronics Washington DC (SPX) Dec 22, 2013 - Constantly losing energy is something we deal with in everything we do. If you stop pedaling a bike, it gradually slows; if you let off the gas, your car also slows. As these vehicles move, they also generate heat from friction. Electronics encounter a similar effect as groups of electrons carry information from one point to another. As electrons move, they dissipate heat, reducing the dis ... more |  |
