Nickelblock Is The Love-hate Relationship Between Nickel And Battery Electrodes
2012-09-28 13:04:12

Images show how nickel, which enhances battery capacity, also appears to hinder charging rates Anyone who owns an electronic device knows that lithium ion batteries could work better and last longer. Now, scientists examining battery materials on the nano-scale reveal how nickel forms a physical barrier that impedes the shuttling of lithium ions in the electrode, reducing how fast the materials charge and discharge. Published last week in Nano Letters, the research also suggests a way to...

Mass spectrometry protein assays that match sensitivity and accuracy of antibody-based clinical tests might speed drug discovery, basic biology research Combining two well-established analytic techniques and adding a twist identifies proteins from blood with as much accuracy and sensitivity as the antibody-based tests used clinically, researchers report this week in Proceedings of the National Academy of Sciences Early Edition online. The technique should be able to speed up development of...

Fueling nuclear reactors with uranium harvested from the ocean could become more feasible because of a material developed by a team led by the Department of Energy's Oak Ridge National Laboratory. The combination of ORNL's high-capacity reusable adsorbents and a Florida company's high-surface-area polyethylene fibers creates a material that can rapidly, selectively and economically extract valuable and precious dissolved metals from water. The material, HiCap, vastly outperforms today's...

PNNL tests adsorbent to extract uranium from the ocean When you take a dip in the ocean, nuclear fuel is probably the farthest thing from your mind. Uranium floats in Earth´s oceans in trace amounts of just 3 parts per billion, but it adds up. Combined, our oceans hold up to 4.5 billion tons of uranium — enough to potentially fuel the world´s nuclear power plantsfor 6,500 years. Countries such as Japan have examined the ocean as a uranium source since the 1960s, but...

With the decommissioning projects costing up to $5billion, it is critical for decommissioning managers to complete their projects on time and within their stringent allocated budgets. (PRWEB) August 10, 2012 In order to do so, important questions have to be asked including: What are the most efficient ways of prioritizing and allocating funds to various projects on site to mitigate fiscal risk? Which contractual model will best suit the project and enable you to work effectively...

Large Synoptic Survey Telescope Advanced By National Science Foundation
2012-07-19 11:47:37

With approval from the National Science Board, the National Science Foundation (NSF) Director will advance the Large Synoptic Survey Telescope (LSST) to the final design stage. This action permits the NSF Director to include funds for LSST construction in a future budget request. To be located in Chile, the LSST is a proposed 8-meter wide-field survey telescope that will survey the entire sky approximately twice per week, delivering a large and comprehensive data set that will transform...

Fish-saving sound threshold recommended for pile driving projects The rise of ocean infrastructure development to tap energy sources such as tides, offshore wind and natural gas will require more pile driving, the practice of pounding long, hollow steel pipes called piles into the ocean floor to support energy turbines and other structures. But pile driving creates loud, underwater booms that can harm fish and other marine animals. Many scientists and regulators have assumed that...

Ongoing saga of building a better fuel cell catalyst goes holistic The design of a nature-inspired material that can make energy-storing hydrogen gas has gone holistic. Usually, tweaking the design of this particular catalyst -- a work in progress for cheaper, better fuel cells -- results in either faster or more energy efficient production but not both. Now, researchers have found a condition that creates hydrogen faster without a loss in efficiency. And, holistically, it requires the...
