11-Sep-2014 Plastics in motion: Exploring the world of polymers
In an experiment at the Department of Energy's SLAC National Accelerator Laboratory using SLAC's Linac Coherent Light Source X-ray laser, a DOE Office of Science User Facility, scientists unraveled the complex behavior of polystyrene, a popular polymer found in packing foams and plastic cups, with a sequence of ultrabright X-ray laser pulses. Their work is detailed in the Aug. 11 edition of Scientific Reports.
4-Sep-2014 SLAC welcomes photon science faculty member Young S. Lee
SLAC's newest faculty member, Young S. Lee, studies the most unusual materials in the most down-to-earth possible way: He and his colleagues make pure crystals of minerals and other compounds and then test them for useful quantum properties, such as the ability to conduct electricity with 100 percent efficiency.
28-Aug-2014 Materials scientists play atomic 'Jenga' and make a surprising discovery
Researchers got a surprise when they built a highly ordered lattice by layering thin films containing lanthanum, strontium, oxygen and iron. Although each layer had an intrinsically nonpolar (symmetric) distribution of electrical charges, the lattice had an asymmetric distribution of charges. The charge asymmetry creates an extra 'switch' that brings functionalities to materials when 'flipped' by external stimuli. The material defects induced polar behavior and can provide a new mechanism for manipulating electricity and magnetism in energy and information technologies.
20-Aug-2014 Junior researchers showing world the way to advanced nuclear fuel design
Two early-career Idaho National Laboratory researchers are earning international attention for their groundbreaking work. They're getting a long-sought look into the 3-D microstructure of irradiated nuclear fuel, then feeding that data into cutting-edge fuel behavior models. Their work will make the design and testing of even safer nuclear fuels more informed and efficient.
20-Aug-2014 SLAC summer institute students take a close look at dark matter
Physicists have good reason to believe 85 percent of the matter in the universe is currently undetectable. But not being able to see it didn't keep students at the 42nd SLAC Summer Institute, held at the Department of Energy's SLAC National Accelerator Laboratory, from learning about it.
20-Aug-2014 Ying Diao honored with 2014 Spicer Award for her work at SSRL
Ying Diao, a SLAC/Stanford postdoctoral researcher who brought key innovations to a printing technique for flexible electronics, solar panels and other uses, has been selected to receive this year's William E. and Diane M. Spicer Young Investigator Award.
18-Aug-2014 Berkeley Lab's SPOT Suite transforms beamline science
For decades, synchrotron light sources have been operating on a manual grab-and-go data management model, but a recent deluge of data is quickly making this practice implausible. So Berkeley Lab X-ray scientists, facility users, computer and computational scientists, teamed up to create new tools for reducing, managing, analyzing and visualizing beamline data.The result of this collaboration is SPOT Suite, and it is already transforming the way scientists run their experiments at the ALS.
31-Jul-2014 Giant electromagnet completes its journey, moves into its new home at Fermilab
One year ago, the 50-foot-wide Muon g-2 electromagnet arrived at the US Department of Energy's Fermi National Accelerator Laboratory in Illinois after traveling 3,200 miles over land and sea from Long Island, N.Y. This week, the magnet took the final few steps of that journey, moving across the Fermilab site and into the new building that now houses it.
17-Jul-2014 Hot plasma partial to bootstrap current
Supercomputers at NERSC are helping plasma physicists 'bootstrap' a potentially more affordable and sustainable fusion reaction. If successful, fusion reactors could provide almost limitless clean energy.
15-Jul-2014 Ames Laboratory home to first-in-nation DNP-NMR instrument to study materials
The US Department of Energy's Ames Laboratory is now the home to a dynamic nuclear polarization (DNP) solid-state nuclear magnetic resonance (NMR) spectrometer that helps scientists understand how individual atoms are arranged in materials. Ames Laboratory's DNP-NMR is the first to be used for materials science and chemistry in the United States.
15-Jul-2014 Physicists detect process even rarer than the long-sought Higgs particle
Scientists running the ATLAS experiment at the Large Hadron Collider (LHC), the world's largest and most powerful 'atom smasher,' report the first evidence of a process that can be used to test the mechanism by which the recently discovered Higgs particle imparts mass to other fundamental particles.
14-Jul-2014 First anniversary gift for Critical Material Institute? Inventions. Eleven of them.
The Critical Materials Institute, an Energy Innovation Hub for the US Department of Energy, celebrated its first anniversary with 11 invention disclosures, all research milestones in a mission to assure the availability of rare earths and other materials critical to clean energy technologies.
The inventions include improved extractive processes, recycling techniques, and substitute materials -- technologies designed to increase production and efficiency of, and reduce reliance on, the use of rare earths and other critical materials.
25-Jun-2014 Massive 30-ton MicroBooNE particle detector moved into place, will see neutrinos this year
On Monday, June 23, the next phase of neutrino physics at Fermilab fell (gently) into place.
The MicroBooNE detector -- a 30-ton, 40-foot-long cylindrical metal tank designed to detect ghostly particles called neutrinos -- was carefully transported by truck across the US Department of Energy's Fermilab site, from the warehouse building it was constructed in to the experimental hall three miles away.
25-Jun-2014 A model for success
Idaho National Laboratory researcher Blaise Collin works with software called PARFUME (particle fuel model) as part of an effort to find new, safer fuel sources for use in nuclear reactors.
6-Jun-2014 MINOS result narrows field for sterile neutrinos
A new result from the long-running MINOS experiment announced this week severely limits the area in which sterile neutrinos could be found and casts more doubt on whether they exist at all.
29-May-2014 Scientists pinpoint creeping nanocrystals behind lithium-ion battery degradation
Scientists from several US Department of Energy national laboratories -- Lawrence Berkeley, Brookhaven, SLAC, and the National Renewable Energy Laboratory -- mapped the nanoscale dynamics of lithium-ion charge cycles and discovered never-before-seen evolution and degradation patterns in two key battery materials.
