Eugene Dumitrescu, Ben Lawrie, Matthew Feldman, and Jordan Hachtel (from left) have conducted investigations aimed at controlling the dissipative nature of quantum systems and materials. The cathodoluminescence microscope used in their work appears at rig
Scientists at the Department of Energy’s Oak Ridge National Laboratory are conducting fundamental physics research that will lead to more control over mercurial quantum systems and materials. Their studies will enable advancements in quantum computing, sensing, simulation, and mater...
Shown as green spheres, microcapsules containing the polymer manganoporphyrin, a newly developed antioxidant (green), the natural antioxidant tannic acid (yellow), and a binding material (blue), can be analyzed for stability and efficiency with neutrons.
Many natural and synthetic antioxidants help defend the body against oxidative stress—a biochemical imbalance that can damage cells and lead to illnesses such as diabetes, Alzheimer’s and cancer. However, these materials can become unstable and less effective over time. A new ...
Researcher Rob Schmidt and his team are using neutrons at HFIR’s CG-1D imaging instrument to study the development of dendrites with hope of improving the design of next-generation lithium ion batteries. Dendrites are thin microscopic fibers that can carr
Researchers are using neutrons to study a battery material that could offer a safer alternative to the flammable liquid component found in most types of lithium-ion batteries. Rob Schmidt, a postdoctoral researcher at the Department of Energy’s Oak Ridge National Laboratory, a...
The Weyl semimetal state is induced when the opposing motions of the electrons cause the Dirac cones to split in two (illustrated on the left by outward facing electrons, opposite the inward facing electrons on the right).
The observation of an abnormal state of matter in a two-dimensional magnetic material is the latest development in the race to harness novel electronic properties for more robust and efficient next-generation devices. Neutron scattering at the Department of Energy’s Oak Ridge ...
ORNL researchers Todd Toops, Charles Finney, and Melanie DeBusk (left to right) hold an example of a particulate filter used to collect harmful emissions in vehicles.

Researchers are looking to neutrons for new ways to save fuel during the operation of filters that clean the soot, or carbon and ash-based particulate matter, emitted by vehicles. A team of researchers from the Energy and Transportation Science Division at the Department of En...
