Titan shines light on high-temperature superconductor pathway
A team led by Thomas Maier of Oak Ridge National Laboratory (ORNL) used the Titan supercomputer at ORNL to simulate cuprates on the path to superconductivity. Maier's team focused on a pivotal juncture on the cuprates' path called the pseudogap phase, an in-between phase before superconductivity in which cuprates exhibit both insulating and conducting properties.

Neutrons reveal unexpected magnetism in rare-earth alloy
Researchers at the Department of Energy's Oak Ridge National Laboratory and their collaborators used neutron scattering to uncover magnetic excitations in the metallic compound ytterbium-platinum-lead. Surprisingly, this three-dimensional material exhibits magnetic properties that one would conventionally expect if the connectivity between magnetic ions was only one-dimensional. A better understanding of those behaviors could lead to applications in quantum computing and improved storage device technologies.

Better combustion for power generation
As US utility companies replace coal-fired power plants with natural gas, a collaboration between GE and Oak Ridge National Laboratory is contributing to efficiency gains in GE's H-class gas turbines. GE researchers produced the first simulation involving multiple gas turbine combustors to study combustion interactions that are impractical to test physically. Advanced simulation is projected to results in a full percentage-point gain in turbine efficiency.

Neutrons probe structure of enzyme critical to development of next-generation HIV drugs
A team led by the Department of Energy's Oak Ridge National Laboratory used neutron analysis to better understand a protein implicated in the replication of HIV, the retrovirus that causes AIDS. The enzyme, known as HIV-1 protease, is a key drug target for HIV and AIDS therapies. The multi-institutional team used neutron crystallography to uncover detailed interactions of hydrogen bonds at the enzyme's active site, revealing a pH-induced proton 'hopping' mechanism that guides its activity.

Neutrons tap into magnetism in topological insulators at high temperatures
Researchers at the Department of Energy's Oak Ridge National Laboratory, Massachusetts Institute of Technology and their collaborators used neutron scattering to reveal magnetic moments in hybrid topological insulator materials at room temperature, hundreds of degrees Fahrenheit warmer than the extreme sub-zero cold where the properties are expected to occur. The discovery promises new opportunities for next-generation electronic and spintronic devices such as improved transistors and quantum computing technologies.

Speedy ion conduction in solid electrolytes clears road for advanced energy devices
A team led by the Department of Energy's Oak Ridge National Laboratory used state-of-the-art microscopy to identify a previously undetected feature, about 5 billionths of a meter (nanometers) wide, in a solid electrolyte. The work experimentally verifies the importance of that feature to fast ion transport, and corroborates the observations with theory. The new mechanism the researchers report in Advanced Energy Materials points out a new strategy for the design of highly conductive solid electrolytes.

Advances in extracting uranium from seawater announced in special issue
The oceans hold more than four billion tons of uranium--enough to meet global energy needs for the next 10,000 years if only we could capture the element from seawater to fuel nuclear power plants. Major advances in this area have been published by the American Chemical Society's journal Industrial & Engineering Chemistry Research. Oak Ridge National Laboratory and Pacific Northwest National Laboratory led more than half of the 30 papers in the special issue.

'Odd couple' monolayer semiconductors align to advance optoelectronics
In a study led by Oak Ridge National Laboratory, scientists synthesized a stack of atomically thin monolayers of two lattice-mismatched semiconductors. Where the two semiconductor layers met, they formed an atomically sharp heterostructure, which generated a photovoltaic response by separating electron-hole pairs that were generated by light. The achievement of creating this atomically thin solar cell shows the promise of synthesizing mismatched layers to enable new families of functional two-dimensional materials.
