 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.

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.

ACS Synthetic BiologyTraining your robot the PaR-PaR way PaR-PaR, a simple high-level, biology-friendly, robot-programming language developed by researchers at JBEI and Berkeley Lab, uses an object-oriented approach to make it easier to integrate robotic equipment into biological laboratories. Effective robots can increase research productivity, lower costs and provide more reliable and reproducible experimental data.

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.

Climatic ChangeEarth sunblock only needed if planet warms easily A new computer analysis of future climate change that considers emissions reductions together with sunlight reduction shows that such drastic steps to cool the earth would only be necessary if the planet heats up easily with added greenhouse gases. The analysis, reported in the journal Climatic Change, might help future policymakers plan for a changing climate.

ACS NanoImproving nanometer-scale manufacturing with infrared spectroscopy While there have been significant breakthroughs in nano-manufacturing, there has been much less progress on measurement technologies that can provide information about nanostructures made from multiple integrated materials. Researchers at the University of Illinois Urbana-Champaign and Anasys Instruments Inc. now report new diagnostic tools that can support cutting-edge nano-manufacturing. Using atomic force microscope based infrared spectroscopy to characterize polymer nanostructures and systems of integrated polymer nanostructures, researchers were able to chemically analyze polymer lines as small as 100 nm
