Scientists have long known that adding tiny defects into otherwise perfect materials can influence the substance’s electronic or magnetic properties. Now, a new study led by Oak Ridge National Laboratory shows that defects in complex oxides do not act independently, which will chang...
Storing carbon dioxide for millennia in geologic formations relies on effective seals. Gernot Rother of Oak Ridge National Laboratory participated in analysis of neutron scattering data taken at the Jülich Centre for Neutron Science during a collaborative study led by Cambridge Univ...
Mass spectrometry and direct sampling come together in a powerful way with a new technology that can identify a material in mere seconds. PenDoc, invented by Gary Van Berkel and Vilmos Kertesz of Oak Ridge National Laboratory, could help in drug discovery, medical diagnostics, food ...
An Oak Ridge National Laboratory study is providing an unprecedented watershed-scale understanding of mercury in soils and sediments. Researchers focused on evaluating mercury and soil properties along the banks of a mercury-contaminated stream in Oak Ridge, Tenn., sampling 145 loca...
Salt and ammonia are key ingredients of a high-efficiency natural gas-fired heat pump system being developed by researchers at Oak Ridge National Laboratory, Rheem and ClimateWell. Potentially, the SaltX system could provide 43 percent greater efficiency than today’s best furn...
Increased power densities in electronics will require more efficient heat sinks, and additive manufacturing combined with a simple thermal annealing process could help designers meet that goal. A team that includes Oak Ridge National Laboratory’s Tong Wu reported that while a 3-D printed aluminum alloy heat sink equaled or measured 10 percent worse than those manufactured conventionally, after the treatment the performance gap vanished.
Production run spot checks of materials for lithium-ion batteries and fuel cells could be a thing of the past because of a process developed at Oak Ridge National Laboratory. The infrared/thermal nondestructive evaluation technique invented by a team led by David Wood examines key parameters such as porosity and thickness of the coating in real time without destroying product.
Since the discovery of high-temperature superconductors — materials that can transport electricity with perfect efficiency at or near liquid nitrogen temperatures (minus-196 degrees Celsius) — scientists have been working to develop a theory that explains their essential physics.
A multi-institution team led by Oak Ridge National Laboratory’s Gaute Hagen used computation to corroborate experimental findings throwing calcium-52’s status as a magic isotope into question.
Researchers at Oak Ridge National Laboratory are using bamboo fiber in 3-D printing experiments to determine whether bio-based feedstock materials are feasible in additive manufacturing.
