A tetradentate ligand selects americium (Am, depicted by green spheres) over europium (Eu, blue spheres). Red indicates oxygen atoms and purple, nitrogen atoms that are the key to the ligand’s selectivity. Image credit: Oak Ridge National Laboratory, U.S.
After used nuclear fuel is removed from a reactor, it emits heat for decades and remains radioactive for thousands of years. The used fuel is a mixture of major actinides (uranium, plutonium), fission products (mainly assorted metals, including lanthanides) and minor actinides (i.e....
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...
Vincent Paquit

Leveraging his expertise in image processing, sensors, and machine learning, Vincent Paquit is devising a control system for additive manufacturing to produce 3D-printed parts that function as well as conventionally produced objects. Paquit’s research sits at the junction of manufacturing technol...

A newly discovered material called BiMn3Cr4O12, represented by the crystal structure, exhibits a rare combination of magnetic and electrical properties. The arrows illustrate the spin moments for the elements chromium (Cr) in yellow and manganese (Mn) in
Materials used in electronic devices are typically chosen because they possess either special magnetic or special electrical properties. However, an international team of researchers using neutron scattering recently identified a rare material that has both. In their paper publis...
ORNL Director Thomas Zacharia (center, seated) visited Robertsville Middle School to present a check in support of the school’s CubeSat efforts.

Last November a team of students and educators from Robertsville Middle School in Oak Ridge and scientists from Oak Ridge National Laboratory submitted a proposal to NASA for their Cube Satellite Launch Initiative in hopes of sending a student-designed nanosatellite named RamSat into...

Juan Carlos Idrobo
For Juan Carlos Idrobo, the scientist’s journey is like taking a test that is only two pages long. You start reading the first page, but you don’t understand any of the questions. You keep reading and after a while a light turns on and you begin to understand. “You work really, re...
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 ...
