18-Aug-2016 Looking from space for nuclear detonations
Sandia National Laboratories, which has been in the business of nuclear detonation detection for more than 50 years, is working on the next generation system.
5-Aug-2016 Researchers combine simulation, experiment for nanoscale 3-D printing
A research team led by Oak Ridge National Laboratory has created a high-power simulation and design process to print free-standing 3-D structures on the nanoscale using focused electron beam induced deposition. The simulation-guided nanomanufacturing method allows researchers to design and construct complex high-fidelity nanostructures with less guesswork.
29-Jul-2016 Stanford, SLAC play key role in new DOE battery consortium
A newly formed Battery500 consortium, including researchers from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory, will receive up to $10 million each year for the next five years to develop a new battery technology that could make electric vehicles go two to three times farther and make them less expensive.
11-Jul-2016 Sandia storing information securely in DNA
Marlene and George Bachand, Sandia National Laboratories bioengineers at the Center for Integrated Nanotechnologies, developed a new method for encrypting and storing sensitive information in DNA.
9-Jun-2016 Ames Laboratory Scientists Leave Their Mark on Future Researchers
Eight out of the past 10 years, Ames Laboratory chemist Aaron Sadow has mentored a Science Undergraduate Laboratory Internships student. Sometimes the mentorship has been for the 10-week summer program and sometimes for the 16-week semester program. On occasion, he's mentored more than one student at a time.
6-Jun-2016 Scientists Use a Frozen Gas to Boost Laser Light to New Extremes
Researchers at the Department of Energy's SLAC National Accelerator Laboratory, Stanford University and Louisiana State University have achieved an even more dramatic HHG shift by shining an infrared laser through argon gas that's been frozen into a thin, fragile solid whose atoms barely cling to each other.
Alex Aiken, director of the new Computer Science Division at the Department of Energy's SLAC National Accelerator Laboratory, has been thinking a great deal about the coming challenges of exascale computing, defined as a billion billion calculations per second. That's a thousand times faster than any computer today. Reaching this milestone is such a big challenge that it's expected to take until the mid-2020s and require entirely new approaches to programming, data management and analysis, and numerous other aspects of computing.
27-May-2016 ORNL researchers use strain to engineer first high-performance, two-way oxide catalyst
Catalysts make chemical reactions more likely to occur. In most cases, a catalyst that's good at driving chemical reactions in one direction is bad at driving reactions in the opposite direction. However, a research team led by the Department of Energy's Oak Ridge National Laboratory has created the first high-performance, two-way oxide catalyst and filed a patent application for the invention. The accomplishment is reported in the Journal of the American Chemical Society.
19-May-2016 Berkeley Lab's OpenMSI licensed to ImaBiotech
Two years ago, Lawrence Berkeley National Laboratory (Berkeley Lab) researchers developed OpenMSI--the most advanced computational tool for analyzing and visualizing mass spectrometry imaging (MSI) data. Last year, this web-available tool was selected as one of the 100 most technologically significant new products of the year by R&D Magazine. Now, OpenMSI has been licensed to support ImaBiotech's Multimaging™ technology in the field of pharmaceutical and cosmetic research and development.
17-May-2016 Lessons from cow eyes
Cornea tissue is a promising biomaterial for Brad Boyce, a Sandia National Laboratories materials scientist. More than a decade after Boyce and his co-workers investigated the biomechanics of dissected cow corneas, their findings have been confirmed in healthy human eyes.
12-May-2016 Extracting miniature diamonds from crude
Stanford and SLAC National Accelerator Laboratory jointly run the world's leading program for isolating and studying diamondoids -- the tiniest possible specks of diamond. Found naturally in petroleum fluids, these interlocking carbon cages weigh less than a billionth of a billionth of a carat (a carat weighs about the same as 12 grains of rice); the smallest ones contain just 10 atoms.
2-May-2016 Could aluminum nitride be engineered to produce quantum bits?
The leading method for creating quantum bits, or qubits, currently involves exploiting the structural defects in diamonds. But using NERSC resources, University of Chicago researchers found that the same defect could be engineered in cheaper aluminum nitride. If confirmed by experiments, this could significantly reduce the cost of manufacturing quantum technologies.
20-Apr-2016 Peering deep into materials with ultrafast science
Creating the batteries or electronics of the future requires understanding materials that are just a few atoms thick and that change their fundamental physical properties in fractions of a second. Cutting-edge facilities at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have allowed researchers like Aaron Lindenberg to visualize properties of these nanoscale materials at ultrafast time scales.
15-Apr-2016 SLAC researchers recreate the extreme universe in the lab
Conditions in the vast universe can be quite extreme: Violent collisions scar the surfaces of planets. Nuclear reactions in bright stars generate tremendous amounts of energy. Gigantic explosions catapult matter far out into space. But how exactly do processes like these unfold? What do they tell us about the universe?
To find out, researchers from the Department of Energy's SLAC National Accelerator Laboratory perform sophisticated experiments and computer simulations that recreate violent cosmic conditions on a small scale in the lab.
5-Apr-2016 Chalice receptors attract metal contaminants with new chemical selectivity
Researchers at Oak Ridge National Laboratory found new ways to influence selectivity for specific positively charged ions (cations) with the addition of simple receptors, not for cations but rather for negatively charged ions (anions). This discovery proves that adding an anion receptor can affect the selectivity of extractants used to separate metals. Better selectivity via the addition of anion receptors to enhance discrimination between metals, such as sodium and cesium, could improve future environmental cleanup efforts.
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.
