One day in December of 2015, bound for a remote ice camp in the interior of Antarctica, Scripps Institution of Oceanography doctoral student Ryan Scott boarded a ski-equipped LC-130 turboprop transport plane at McMurdo Station at the south tip of Ross Island. It was austral summer and the temperature outside hovered around -4 degrees Celsius.
Argonne researchers have identified a nickel oxide compound as an unconventional but promising candidate material for high-temperature superconductivity. The project combined crystal growth, X-ray spectroscopy and computational theory.
Engineers at the University of California San Diego have developed new electrolytes that enable lithium batteries to run at temperatures as low as -60 degrees Celsius with excellent performance -- in comparison, today's lithium-ion batteries stop working at -20 degrees Celsius. The new electrolytes also enable electrochemical capacitors to run as cold as -80 degrees Celsius -- their current limit is -40 degrees Celsius.

A new device design allows ten-fold increase in spin currents, laying the path to use in computing and high-efficiency electronics.
An X-ray technique, coupled with theoretical work, revealed how oxygen atoms embedded very near the surface of a copper sample had a more dramatic effect on the early stages of the reaction with carbon dioxide (CO2) than earlier theories could account for. This information could prove useful in designing new types of materials to further enhance reactions and make them more efficient in converting carbon dioxide into liquid fuels and other products.
Microbes play important roles in regulating Earth's biogeochemical cycles and in Nature Biotechnology, U.S. Department of Energy Joint Genome Institute scientists report the release of 1,003 phylogenetically diverse bacterial and archaeal reference genomes--the single largest release to date.
Heterogeneous nanostructured materials are widely used in various optoelectronic devices, including solar cells. However, the nano-interfaces contain structural defects that can affect performance. Calculations run at NERSC helped researchers ID the root cause of the defects in two materials and provide design rules to avoid them.
With the most highly focused power of the world's most powerful X-ray laser, scientists from a number of institutions around the world - including Argonne National Laboratory - have conducted a new experiment that takes apart molecules electron by electron.
Neutron scattering has revealed in unprecedented detail new insights into the exotic magnetic behavior of a material that could pave the way for quantum calculations far beyond the limits of a computer's binary code. A research team led by the Department of Energy's Oak Ridge National Laboratory has confirmed magnetic signatures likely related to Majorana fermions--elusive particles that could be the basis for a quantum bit, or qubit, in a two-dimensional graphene-like material, alpha-ruthenium trichloride. The results, published in the journal Science, verify and extend a 2016 Nature Materials study in which the team first proposed this unusual behavior in the material.
A team of scientists in the Pacific Northwest has solved the 3-D structure of 1,000 proteins from more than 70 organisms that cause infectious disease in people. The proteins come from microbes that cause several serious diseases, including tuberculosis, Listeria, Giardia, Ebola, anthrax, C. diff., Legionella, Lyme, chlamydia and the flu.
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have developed a new way to track dynamic molecular features in soft materials, including the high-frequency molecular vibrations that transmit waves of heat, sound, and other forms of energy.
