 NatureMore bang for the biofuel buck Berkeley Lab researchers have shown that a fermentation process used in World War I to make cordite for bullets and artillery shells, in combination with a modern palladium catalyst could produce gasoline, diesel or jet fuel from the sugars found in biomass.

ScienceNanocrystals and nickel catalyst substantially improve light-based hydrogen production Hydrogen is an attractive fuel source because it can easily be converted into electric energy and gives off no greenhouse emissions. A group of chemists at the University of Rochester is adding to its appeal by increasing the output and lowering the cost of current light-driven hydrogen-production systems.

November 2012 story tips 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. Recommendations to accelerate climate modeling to learn more about climate's regional ramifications and future effects. 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. Contact: Ron Walli

Nature ChemistryResearchers make strides toward selective oxidation catalysts Solid catalysts tend to be highly reactive, but more efficient chemical processes require that catalysts be more scrupulous about their reactants. Now Northwestern University researchers have a new method for making selective oxidation catalysts, a step that could lead to greener energy.

Proceedings of the National Academy of SciencesFolding funnels key to biomimicry Berkeley Lab researchers have shown that a concept widely accepted as describing the folding of a single individual protein is also applicable to the self-assembly of multiple proteins. Their findings provide important guidelines for future biomimicry efforts, particularly for device fabrication and nanoscale synthesis.

Reclaiming rare earths Recycling keeps paper, plastics, and even jeans out of landfills. Could recycling rare-earth magnets do the same? Perhaps, if the recycling process can be improved. Scientists at the US Department of Energy's Ames Laboratory are working to more effectively remove the neodymium, a rare earth element, from the mix of other materials in a magnet. Initial results show recycled materials maintain the properties that make rare-earth magnets useful.

Americans use more efficient and renewable energy technologies Americans used less energy in 2011 than in the previous year due mainly to a shift to higher-efficiency energy technologies in the transportation and residential sectors. Meanwhile, less coal was used but more natural gas was consumed according to the most recent energy flow charts released by Lawrence Livermore National Laboratory. Contact: Anne Stark

Physical Review LettersMeasuring Table-Top Accelerators’ State-of-the-Art Beams Accurate tests of the beam quality of laser plasma accelerators (LPAs) assume new importance with the approaching advent of the one-meter-long, 10-billion-electron-volt Berkeley Lab Laser Accelerator (BELLA), bringing the promise of "table-top accelerators" closer to realization. Accelerator scientists at Lawrence Berkeley National Laboratory have devised novel techniques for characterizing extraordinarily short beam pulses in the complex environment of LPAs, including the metric known as slice-energy spread.

Nature CommunicationsHigh-pressure science gets super-sized The study of materials at extreme conditions took a giant leap forward with the discovery of a way to generate super high pressures without using shock waves whose accompanying heat turns solids to liquid. This discovery will allow scientists for the first time to reach static pressure levels exceeding four million atmospheres, a high-pressure environment where new unique compounds could be formed, materials change their chemical and physical properties, and metals become insulators.

Iowa State researchers double down on heat to break up cellulose, produce fuels and power 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.

Astrophysical JournalMilky Way's black hole getting ready for snack Get ready for a fascinating eating experience in the center of our galaxy. The event involves a black hole that may devour much of an approaching cloud of dust and gas known as G2. A supercomputer simulation prepared by two Lab physicists and a former postdoc suggests that some of G2 will survive, although its surviving mass will be torn apart, leaving it with a different shape and questionable fate.

Physics Review LettersState-of-the-art beams from table-top accelerators "Table-top accelerators" – laser plasma accelerators (LPAs) that propel electron pulses to high energies within a few centimeters – promise far less expensive future accelerators with far less environmental impact than today's conventional machines. Scientists at Lawrence Berkeley National Laboratory have devised novel methods to test the quality of uniquely challenging LPA beams. Contact: Paul Preuss

Angewandte Chemie International EditionNew cobalt-graphene catalyst could challenge platinum for use in fuel cells There's a new contender in the race to find an inexpensive alternative to platinum catalysts for use in hydrogen fuel cells. Brown University chemist Shouheng Sun and his students have developed a new material -- a graphene sheet covered by cobalt and cobalt-oxide nanoparticles -- that can catalyze the oxygen reduction reaction nearly as well as platinum does and is substantially more durable.
