22-Oct-2014 SLAC steps up to the plate at Bay Area Science Festival
The Department of Energy's SLAC National Accelerator Laboratory will once again participate as an exhibitor in Discovery Days at AT&T Park on Saturday, Nov. 1, from 11 a.m. to 4 p.m. The concluding highlight of the fourth annual 10-day Bay Area Science Festival -- which is free and open to the public -- will transform the home of the San Francisco Giants into a science wonderland with activities for kids ages 0 to 14.
20-Oct-2014 Puzzling new behavior found in high-temperature superconductors
Research by an international team led by SLAC and Stanford scientists has uncovered a new, unpredicted behavior in a copper oxide material that becomes superconducting -- conducting electricity without any loss -- at relatively high temperatures.
17-Oct-2014 Atomic trigger shatters mystery of how glass deforms
A new study at the Department of Energy's Oak Ridge National Laboratory, published Sept. 24 in Nature Communications, has cracked one mystery of glass to shed light on the mechanism that triggers its deformation before shattering. The study improves understanding of glassy deformation and may accelerate broader application of metallic glass, a moldable, wear-resistant, magnetically exploitable material that is thrice as strong as the mightiest steel and ten times as springy.
6-Oct-2014 Fermilab's 500-mile neutrino experiment up and running
It's the most powerful accelerator-based neutrino experiment ever built in the United States, and the longest-distance one in the world. It's called NOvA, and after nearly five years of construction, scientists are now using the two massive detectors -- placed 500 miles apart -- to study one of nature's most elusive subatomic particles.
3-Oct-2014 Accelerating the fight against cancer
As charged-particle therapies grow in popularity, physicists are working with other experts to make them smaller, cheaper and more effective -- and more available to cancer patients in the United States.
1-Oct-2014 Brookhaven and the Daya Bay Neutrino Experiment
The Daya Bay Collaboration, an international group of scientists studying the subtle transformations of subatomic particles called neutrinos, is publishing its first results on the search for a so-called sterile neutrino, a particle that could have a profound impact on our understanding of the universe. US Daya Bay Chief Scientist Steve Kettell of Brookhaven National Laboratory offers commentary on the implications of this research.
25-Sep-2014 Breakthrough: Nanote creates more electron beam than large laser system
A collaboration led by RadiaBeam Technologies, a California-based technology firm actively involved in accelerator R&D, is designing an electron beam source that doesn't need a laser. The team led by Luigi Faillace, a scientist at RadiaBeam, is testing a carbon nanotube cathode -- about the size of a nickel -- in Fermilab's High-Brightness Electron Source Lab that completely eliminates the need for a room-sized laser system currently used to generate the electron beam.
24-Sep-2014 Ames Laboratory 3-D printing technology research taking shape
Scientists at the US Department of Energy's Ames Laboratory see amazing potential in 3-D printing and additive manufacturing, and are focusing research toward further advances in the technology. Ames Lab researchers have at their command four experimental 3-D printers that cover a range of unique capabilities.
22-Sep-2014 Ames Laboratory and Japanese R&D organization discuss rare earths
The US Department of Energy's Ames Laboratory and the New Energy and Industrial Technology Development Organization, a Japanese energy and industrial technology research and development organization, held a bilateral meeting on rare-earth materials in Ames on Sept. 10.
18-Sep-2014 Factors underlying nuclear fuel swelling seen at nanoscale for first time
Understanding factors that drive nuclear fuel swelling will help engineers develop higher performance fuels, which could be even safer and more efficient than those used in current nuclear energy plants. As uranium atoms split to produce energy, fission products build up within fuel rods, which impacts nuclear fuel performance inside a reactor. But, a clear picture of the size and location of these solid fission products has been elusive until now.
17-Sep-2014 Predicting performance
Lignin, a low-cost byproduct of the pulp, paper and biofuels industries, can be transformed into a cheaper version of highly engineered graphite through a simple and industrially scalable manufacturing process.
12-Sep-2014 CMI hosts EU, Japan to discuss global critical materials strategy
Finding ways to ensure the planet's supply of rare earths and other materials necessary for clean energy technologies is a global challenge, and experts from around the world gathered to meet it at the fourth annual EU-US-Japan Trilateral Conference on Critical Materials on Sept. 8.
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.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
