1-Apr-2016 What are aerosols?
Art Sedlacek, an atmospheric scientist at Brookhaven National Laboratory, has flown on planes outfitted with high tech equipment through wildfire plumes and over the ocean, and has visited stations all over the globe to observe aerosols and understand the potentially big impact these suspensions of tiny particles can have on climate.
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.
21-Mar-2016 Sisters in science
Emma and Molly White and Ru-Shyan and Ru-Huey Yen, a pair of twin sisters and close friends who met in high school 16 years ago. Flash forward to today, and the four all have science-based careers, and look back at their shared-sisterhood-times-two as vital in getting them to where they are today.
21-Mar-2016 Bump in LHC data has physicists electrified
In December, the ATLAS and CMS experiments reported what could be the first hint of a new massive particle that spits out two photons as it decays. Now, physicists are presenting their latest analyses at the Moriond conference in La Thuile, Italy, including a full investigation of this mysterious bump. After carefully checking, cross-checking and rechecking the data, both experiments have come to the same conclusion -- the bump is still there.
14-Mar-2016 X-ray studies at SLAC and Berkeley Lab aid search for Ebola cure
In experiments carried out partly at the Department of Energy's SLAC National Accelerator Laboratory, scientists have determined in atomic detail how a potential drug molecule fits into and blocks a channel in cell membranes that Ebola and related 'filoviruses' need to infect victims' cells.
14-Mar-2016 Brookhaven Lab named an NVIDIA GPU Research Center
NVIDIA, the world leader in visual computing, has named the US Department of Energy's Brookhaven National Laboratory a 2016 GPU Research Center. Brookhaven Lab was recognized for its use of graphics processing unit (GPU)-accelerated computing to conduct research in fields including materials science, physics, and climate science, and for its vision to further the application of GPU-accelerated computing in those and other research fields with a high computational demand.
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.
4-Mar-2016 New ways of looking at glass-to-metal seals
Components housed in stainless steel for protection against extreme environments require paths for electricity to power them and communicate with them. Those paths in turn need a reliable insulation seal, so strong bonds between materials for airtight seals are crucial.
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.
25-Feb-2016 Fermilab scientists discover new 4-flavor particle
Scientists on the DZero collaboration at the US Department of Energy's Fermilab have discovered a new particle -- the latest member to be added to the exotic species of particle known as tetraquarks.
22-Feb-2016 Updated workflows for new LHC era
After a massive upgrade, the Large Hadron Collider (LHC) is smashing particles at an unprecedented 13 teraelectronvolts (TeV) -- nearly double the energy of its previous run. In just one second, the LHC can now produce up to 1 billion collisions and generate up to 10 gigabytes of data.
To deal with the new data deluge, researchers working on the LHC's ATLAS experiment are relying on updated workflow management tools developed primarily by Berkeley Lab researchers.
19-Feb-2016 Physicists zoom in on gluons' contribution to proton spin
By analyzing the highest-energy proton collisions at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the US Department of Energy's (DOE) Brookhaven National Laboratory, nuclear physicists have gotten a glimpse of how a multitude of gluons that individually carry very little of the protons' overall momentum contribute to the protons' spin.
19-Feb-2016 New satellite with superior X-ray vision launched
Although the star-covered night sky is regarded by many as a synonym of serenity, the cosmos is in fact a rather hostile place. It hosts many extreme environments that would instantaneously eradicate any life nearby. A new space mission is about to reveal this violent nature in greater detail than ever before: on Feb. 17, the Japan Aerospace Exploration Agency launched its ASTRO-H satellite -- a very precise and sensitive eye for X-rays emerging from hot and energetic processes in space.
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.
