Physicists from around the world gathered at the University of California, Irvine this past summer for a symposium in honor of Wei-li Lee, a senior physicist at the US Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL).
3-Nov-2016 Peering into batteries: X-rays reveal lithium-ion's mysteries
Scientists are using x-rays from the national laboratories' advanced light sources to study the movement and structure of lithium-ion batteries in real time, as the batteries function. This technique led to the development of the cathode used in the Chevrolet Volt and is now being used to further improve our understanding of batteries.
19-Oct-2016 Underground science: Berkeley Lab digs deep for clean energy solutions
About a mile beneath the Earth's surface in an old gold mine, Lawrence Berkeley National Laboratory (Berkeley Lab) scientists have built an observatory to study how rocks fracture. The knowledge they gain could ultimately help reduce greenhouse gas emissions and accelerate deployment of clean energy technologies.
1-Sep-2016 Blowing bubbles to catch carbon dioxide
Sandia and UNM researchers developed a bio-inspired bubble-like membrane to capture CO2 from coal-fired power plants efficiently. The CO2 Memzyme could capture CO2 equivalent to planting 63 million trees and letting them grow for 10 years from just one power plant.
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.
29-Jun-2016 PNNL's Richard Moss to help guide new phase of US National Climate Assessment
Today the National Oceanic and Atmospheric Administration opened a new chapter of the National Climate Assessment by announcing the appointment of new members to the Advisory Committee for the Sustained National Climate Assessment. Chairing this 15-member committee will be Richard Moss, a senior scientist with the Department of Energy's Pacific Northwest National Laboratory.
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.
12-May-2016 Solving the biomass puzzle
Biomass holds great promise as a petroleum replacement, but unlocking its true potential remains a puzzle. A group of researchers at Iowa State University and the US Department of Energy's Ames Laboratory hope to develop the pieces of that puzzle to create a clearer picture of what takes place within a plant and how that applies to its downstream uses as biomass.
11-May-2016 Sandia/California invites community to 60th anniversay celebration
Sandia will commemorate the 60th anniversary of its California site with a community event in downtown Livermore on Saturday, May 21 from 10 a.m. to 2 p.m. Held at the Bankhead Theater, 2400 First Street, it will feature technology displays and demonstrations, national security speakers, hands-on science activities and recruiting.
26-Apr-2016 The Pellet Stove Design Challenge: We have a winner!
At Brookhaven Lab last week, seven finalists competed to be designated the top-performing pellet stove. The three-day Pellet Stove Design Challenge, organized by the Alliance for Green Heat, featured stove demonstrations and testing as well as presentations and round-table discussions on a variety of issues.
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.
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.
28-Mar-2016 ORNL scientists show charged salts can extract specific central lanthanide elements
Researchers at Oak Ridge National Laboratory wanted to find out if it was possible to make a molecule that could selectively bind to metal cations in the middle of the lanthanide series. The team provided a proof-of-principle by successfully creating a new ligand that selectively extracted central lanthanides. Easier accessibility to these central lanthanides could lead to advances in materials for technologies such as lasers, strong magnets, lights and neutron-absorbing control rods in nuclear reactors.
24-Mar-2016 New catalyst is 3 times better at splitting water
With a combination of theory and clever, meticulous gel-making, scientists from the Department of Energy's SLAC National Accelerator Laboratory and the University of Toronto have developed a new type of catalyst that's three times better than the previous record-holder at splitting water into hydrogen and oxygen -- the vital first step in making fuels from renewable solar and wind power.
9-Mar-2016 ORNL's benchmark data set validates global nuclear reactor codes
A re-analysis of nuclear fuel rods from a commercial reactor used improved radiochemical methods developed at Oak Ridge National Laboratory and characterized more than 50 different isotopes and 16 elements with high accuracy. It produced an experimental data set with uncertainties many times smaller than those obtained by the earlier radiochemical analysis. Modeling and simulation experts at ORNL applied the more accurate experimental data to validate codes widely used by the nuclear safeguards research community.
8-Mar-2016 'Keiser rigs' stress materials to the max to improve products for power, propulsion
For decades, environmental exposure chambers at the Department of Energy's Oak Ridge National Laboratory, including some called Keiser rigs, have subjected materials to corrosive gases, crushing pressures and calamitous heat. The extreme environments created in the Keiser rigs have spurred advances and continue to do so by providing insight into the conditions under which materials fail so researchers can apply the lessons learned to design better materials for power and propulsion applications.
3-Mar-2016 Pushing boundaries
Solid-liquid interface studies have a long history at EMSL. The insights gained from this research spans areas including terrestrial ecosystems, energy materials, aerosols and biological systems. With improved understanding of interfacial events, scientists working at EMSL have developed more predictive models and made significant advances in addressing real-world challenges. EMSL's focus on solid-liquid interface research has pushed the development of new instruments and techniques to better study these complex surfaces for even greater scientific results.
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.
