  1. Meeting of Rivers, Seas May Be Source of PowerWhere the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers at MIT.The researchers evaluated an emerging method of power generation, called pressure retarded osmosis (PRO), in which two streams of different salinity are mixed to produce energy. In principle, a PRO system would take in river water and seawater on either side of a semi-permeable membrane. Through osmosis, water from the less-salty stream would cross the membrane to a pre-pressurized saltier side, creating a flow that can be sent through a turbine to recover power.Read more: http://www.laboratoryequipment.com/news/2014/08/meeting-rivers-seas-may-be-source-power

  3. Sunblock is Possible Hazard to Sea LifeThe sweet and salty aroma of sunscreen and seawater signals a relaxing trip to the shore. But, scientists are now reporting that the idyllic beach vacation comes with an environmental hitch. When certain sunblock ingredients wash off skin and into the sea, they can become toxic to some of the ocean’s tiniest inhabitants, which are the main course for many other marine animals. Their study appears in the ACS journal Environmental Science & Technology.Read more: http://www.laboratoryequipment.com/news/2014/08/sunblock-possible-hazard-sea-life

U.S. Coal Used is Asia Could Slash EmissionsUnder the right scenario, exporting U.S. coal to power plants in South Korea could lead to a 21 percent drop in greenhouse gas emissions compared to burning the fossil fuel at plants in the U.S., according to a new Duke Univ.-led study.“Despite the large amount of emissions produced by shipping the coal such a long distance, our analysis shows that the total emissions would drop because of the superior energy efficiency of South Korea’s newer coal-fired power plants,” said Dalia Patiño-Echeverri, assistant professor of energy systems and public policy at Duke.Read more: http://www.laboratoryequipment.com/news/2014/08/us-coal-used-asia-could-slash-emissions

  9. Old Batteries Could Be Recycled into Solar Cells

    A system proposed by researchers at MIT recycles materials from discarded car batteries — a potential source of lead pollution — into new, long-lasting solar panels that provide emissions-free power.

    The system is described in a paper in the journal Energy and Environmental Science, co-authored by Profs. Angela Belcher and Paula Hammond, graduate student Po-Yen Chen and three others. It is based on a recent development in solar cells that makes use of a compound called perovskite — specifically, organolead halide perovskite — a technology that has rapidly progressed from initial experiments to a point where its efficiency is nearly competitive with that of other types of solar cells.

  11. Shale Oil ‘Dividend’ Could Pay for Smaller Footprint

    Unanticipated economic benefits from the shale oil and gas boom could help offset the costs of substantially reducing the U.S.’s carbon footprint, Purdue agricultural economists say. Wally Tyner and Farzad Taheripour estimate that shale technologies annually provide an extra $302 billion to the U.S. economy relative to 2007, a yearly “dividend” that could continue for at least the next two decades, Tyner said.

    Using an economic model, they found that “spending” part of this dividend on slashing the nation’s carbon emissions by about 27 percent — about the same amount set forth in the U.S. Environmental Protection Agency’s recently proposed Clean Power Plan — would reduce the shale dividend by about half.

  13. Model Predicts Water Scarcity, Climate Change in 2095What will a global water scarcity map look like in 2095? Radically different, according to scientists at Pacific Northwest National Laboratory, depending on the type and the stringency of the climate mitigation policies chosen to reduce carbon pollution.In a first of its kind comprehensive analysis, the researchers, working at the Joint Global Change Research Institute, used a unique modeling capability that links economic, energy, land-use and climate systems to show the effects of global change on water scarcity. When they incorporated water use and availability in this powerful engine and ran scenarios of possible climate mitigation policy targets, they found that without any climate policy to curb carbon emissions, half the world will be living under extreme water scarcity. Some climate mitigation policies, such as increasing growth of water-hungry biofuels, may exacerbate water scarcity.Read more: http://www.laboratoryequipment.com/news/2014/08/model-predicts-water-scarcity-climate-change-2095

  19. Scientists Uncover Powerful Click Chemistry Reactivity

    Chemists led by Nobel laureate K. Barry Sharpless at The Scripps Research Institute (TSRI) have used his click chemistry to uncover unprecedented, powerful reactivity for making new drugs, diagnostics, plastics, smart materials and many other products.

    The new SuFEx — Sulfur Fluoride Exchange — reactions enable chemists to link molecules of their choice together using derivatives of a common commercial chemical considered essentially inert. The Sharpless team made this chemical reliably and predictably reactive. Astonishingly, acid-base constraints are rarely a concern, though they are central to nature’s chemistry and an enormous hurdle for chemists. The stabile linkers are also non-polar and can enter cells, so have potential for crossing the blood-brain barrier.

  27. Math Helps Keep Cost of Electric Buses Down

    EPFL scientists have developed a mathematical model to minimize the infrastructure and operational costs of the TOSA ultra-rapid rechargeable electric bus system.

    Are electric buses that recharge themselves at bus stops the future of public transportation? For now they’re part of the arsenal deployed in the name of sustainable mobility. In Geneva, ABB Sécheron and its partners — TPG, SIG and OPI — have just concluded a successful pilot operation of their electric bus system TOSA. Instead of using overhead lines, the buses power up in just 15 seconds at specific stops and at the terminus station. How can this technology that frees trolleybuses from electric wires be integrated into the public transport network?
