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.

Cleaning up hybrid battery electrodes improves capacity and lifespan
Hybrid batteries that charge faster than conventional ones could have significantly better electrical capacity and long-term stability when prepared with a gentle-sounding way of making electrodes. Called ion soft-landing, the high-precision technique resulted in electrodes that could store a third more energy and had twice the lifespan compared to those prepared by a conventional method, the researchers report in Nature Communications.

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.

Elusive state of superconducting matter discovered after 50 years
Scientists at the US Department of Energy's Brookhaven National Laboratory, Cornell University, and collaborators have produced the first direct evidence of a state of electronic matter first predicted by theorists in 1964 -- a 'Cooper pair density wave.' The discovery, described in a paper published online April 13, 2016, in Nature, may provide key insights into the workings of high-temperature superconductors.
