First direct evidence that a phase of matter competes with high-temperature superconductivity
Scientists have found the first direct evidence that a mysterious phase of matter known as the 'pseudogap' competes with high-temperature superconductivity, robbing it of electrons that otherwise might pair up to carry current through a material with 100 percent efficiency.

Crown ethers flatten in graphene for strong, specific binding
A team led by the Department of Energy's Oak Ridge National Laboratory has discovered a way to dramatically increase the selectivity and binding strength of crown ethers by incorporating them within a rigid framework of graphene. Strong, specific electrostatic binding of crown ethers may advance sensors, chemical separations, nuclear-waste cleanup, extraction of metals from ores, purification and recycling of rare-earth elements, water purification, biotechnology, energy production in durable lithium-ion batteries, catalysis, medicine and data storage.

Studies look at long-term aging of electronics in nuclear weapons
Researchers have studied radiation effects since the early days of nuclear weapons. But a 30-year program Sandia National Laboratories began in 2006 will provide real-time data for the first time on how electronics age within a weapon.

Rattled atoms mimic high-temperature superconductivity
An experiment at the Department of Energy's SLAC National Accelerator Laboratory provided the first fleeting glimpse of the atomic structure of a material as it entered a state resembling room-temperature superconductivity -- a long-sought phenomenon in which materials might conduct electricity with 100 percent efficiency under everyday conditions.

Optimized algorithms boost combustion research
Turbulent combustion simulations, used in the design of more fuel-efficient combustion systems, have gotten their own efficiency boost, thanks to researchers from Berkeley Lab's Computational Research Division. They developed new algorithmic features that streamline turbulent flame simulations, which are commonly used in the design of combustion systems such as diesel engines; after testing the enhanced code on NERSC supercomputers, they were able to achieve dramatic improvements in simulation times, which will help reduce the time -- and thus the cost -- of designing new engines.

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.

A better prosthesis: Sandia invents sensor to learn about fit; system to make fit better
Sandia National Laboratories researcher Jason Wheeler has been working to make prostheses more comfortable in a twofold approach: sensors that detect how the prosthesis fits and a system to make the fit better. He points out that it doesn't matter how high-tech a prosthesis is if it's not comfortable.

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.
