In the first-ever experiment of its kind, researchers have demonstrated that clean energy hydrogen can be produced from water splitting by using very small metal particles that are exposed to sunlight. In the article, "Outstanding activity of sub-nm Au clusters for photocatalytic hydrogen production," published in the journal Applied Catalysis B: Environmental, Alexander Orlov, PhD, an Assistant Professor of Materials Science & Engineering at Stony Brook University, and his colleagues from Stony Brook and Brookhaven National Laboratory, found that the use of gold particles smaller than one nanometer resulted in greater hydrogen production than other co-catalysts tested.

U.S. Forest Service and Oak Ridge National Laboratory scientists have found that rising levels of ozone may amplify the impacts of higher temperatures and reduce streamflow from forests to rivers, streams and other water bodies. A committee formed by the National Academy of Sciences and the National Research Council has released a report (http://www.nap.edu/catalog.php?record_id=13430) of recommendations to accelerate climate modeling to learn more about climate's regional ramifications and future effects. When four of the nation's most energy-efficient houses are sold, the new homeowners can opt to allow the research project to continue, providing additional data that could make houses of tomorrow even better. Ethanol blends of 10 to 25 percent could potentially have more fuel pump compatibility issues than higher blends, according to a study conducted by a team led by Mike Kass of Oak Ridge National Laboratory's Fuels and Engines Research Group.
It looks like Mother Nature was wasting her time with a multimillion-year process to produce crude oil. Michigan Engineering researchers can "pressure-cook" algae for as little as a minute and transform an unprecedented 65 percent of the green slime into biocrude.
A new study shows that jumping can be more complicated than it might seem. In research that could extend the range of future rescue and exploration robots, scientists have found that hopping robots could dramatically reduce the amount of energy they use by adopting a unique two-part "stutter jump."
Photovoltaic cell efficiency may soon get a big boost, thanks to next-generation antireflection coatings crafted from nanomaterials capable of cutting down on the amount of light reflected away from a cell's surface.
Scientists from the National Renewable Energy Laboratory (NREL) have demonstrated the first solar cell with external quantum efficiency (EQE) exceeding 100 percent for photons with energies in the solar range.
Even if the weather outside is frightful, solar cells can still generate a delightful amount of electricity.
Iowa State University engineers and researchers have built and are testing a bio-oil gasifier. It will allow them to combine two thermochemical technologies to produce the next generation of fuels from renewable sources such as corn stalks and wood chips.
Initial results of clay samples from western North Dakota show varying percentages of alumina content, a finding of interest to the North Dakota Geological Survey that commissioned the study. Scientists in a lab at North Dakota State University's Center for Nanoscale Science and Engineering (CNSE), Fargo, are completing analysis of the clay, often referred to as kaolin, which could eventually play a role in proppants used for hydraulic fracturing in North Dakota oil exploration.
Discovery of new class of power inverter could mean cheaper, faster hybrid vehicles and other green products.
A research team led by Iowa State University's Laura Jarboe is working to develop hungry, robust microbes that can ferment biofuels from the bio-oil produced by rapidly heating biomass such as corn stalks and sawdust.

Magnetically imploded tubes, intended to help produce controlled nuclear fusion at scientific "break-even" energies or better within the next few years, have functioned successfully in preliminary tests.
Sandia and OurEnergyPolicy.org Release "Goals of Energy Policy" Poll That Suggests Call for Ambitious Agenda
U.S. energy policy should simultaneously pursue security of its energy supply, economic stability and reduced environmental impacts, says a national poll of energy professionals jointly prepared by Sandia National Laboratories and OurEnergyPolicy.org. The findings of the national poll, "The Goals of Energy Policy," show that the vast majority -- more than 85 percent -- of the 884 energy professionals surveyed prefer policymaking that pursues all three goals at once.
Wind turbines could power half the world's future energy demands with minimal environmental impact, according to new research published by University of Delaware and Stanford University scientists in the Proceedings of the National Academy of Sciences.
Oak Ridge National Laboratory and Oklahoma's ClimateMaster Inc. have collaborated to develop a ground source heat pump that can reduce a homeowner's electric bill by up to 60 percent. Owners of electric cars could kiss that cumbersome cord goodbye without losing efficiency because of a proprietary technology developed at Oak Ridge National Laboratory. With the first demonstration of a dual-fuel advanced combustion cycle in a modified multi-cylinder engine, researchers have moved closer to delivering on the promise of increased fuel efficiency and reduced emissions.
Spinach power has just gotten a big boost. Vanderbilt researchers have combined the photosynthetic protein that converts light into electrochemical energy in spinach with silicon, the material used in solar cells, in a fashion that produces substantially more electrical current than has been reported by previous "biohybrid" solar cells.
Researchers at RTI International have developed a new solar technology that could make solar energy more affordable, and thus speed-up its market adoption.
The same type of microwave oven technology that most people use to heat up leftover food has found an important application in the solar energy industry, providing a new way to make thin-film photovoltaic products with less energy, expense and environmental concerns.
Knowing the position of missing oxygen atoms could be the key to cheaper solid oxide fuel cells with longer lifetimes. New microscopy research from the Department of Energy's Oak Ridge National Laboratory is enabling scientists to map these vacancies at an atomic scale.
Scientists today unveiled new technology intended to move soybeans, second only to corn as the top food crop in the U.S., along the same use-to-all path of corn and crude oil as a raw material for a wider portfolio of products. They described it - a new integrated soybean biorefinery - at the 244th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, being held here through Thursday.
