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.

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.

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.

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.

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.

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.

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.

'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.

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.

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.

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.

Canfield to head APS Condensed Matter Division
Ames Laboratory physicist Paul Canfield has always been a vocal proponent of his field, condensed matter physics, but he's about to take it up a notch. In March, Canfield will begin a four-year leadership stint heading up the Condensed Matter Physics Division of the American Physical Society. APS recently announced that Canfield had been elected vice-chair of the CMP division.

Cracking cases
A group of nuclear detectives at the Department of Energy's Oak Ridge National Laboratory takes on tough challenges, from detecting illicit uranium using isotopic 'fingerprints' to investigating Presidential assassination conspiracies. 'A very big capability at Oak Ridge exists for nuclear analytics, all the way from helping commercial production of nuclear power to making sure the world's nuclear materials are properly accounted for,' said ORNL's Joseph Giaquinto, leader of the Nuclear Analytical Chemistry and Isotopics Laboratories.

ORNL researchers use neutrons to gain insight into battery inefficiency
Scientists at Oak Ridge National Laboratory are improving the lifetimes of rechargeable batteries that run on lithium, a small atom that can pack tightly into graphite anode materials. The valuable ions are depleted as a battery charges, and they are also lost to the formation of a thin coating on a battery's anode during initial charging. ORNL researchers used two powerful neutron science facilities to try to understand the dynamics behind this phenomenon.

ORNL's thermal cameras snoop beneath surfaces to reveal materials' secrets
In 1995, the Department of Energy's Continuous Fiber Ceramic Composite program, led by Oak Ridge National Laboratory, bought a high-speed infrared camera -- one of the first available for purchase outside the military. Since then, ORNL has acquired at least 10 additional IR cameras for use in a spectrum of projects. The cameras have mapped changing temperatures as heat flows through objects from gears to artwork.
