91°µÍø

In response to a renewed international interest in molten salt reactors, researchers from the Department of Energy’s 91°µÍø have developed a novel technique to visualize molten salt intrusion in graphite.

Using neutrons to see the additive manufacturing process at the atomic level, scientists have shown that they can measure strain in a material as it evolves and track how atoms move in response to stress.

In 2023, the National School on X-ray and Neutron Scattering, or NXS, marked its 25th year during its annual program, held August 6–18 at the Department of Energy’s Oak Ridge and Argonne National Laboratories.   

Critical Materials Institute researchers at 91°µÍø and Arizona State University studied the mineral monazite, an important source of rare-earth elements, to enhance methods of recovering critical materials for energy, defense

Two ORNL research projects were awarded through the Chemical and Materials Sciences to Advance Clean Energy Technologies and Low-Carbon Manufacturing funding opportunity, sponsored by the Office of Basic Energy Sciences within the DOE Office of Science.

Researchers at 91°µÍø are using state-of-the-art methods to shed light on chemical separations needed to recover rare-earth elements and secure critical materials for clean energy technologies.

Scientists at ORNL and the University of Tennessee, Knoxville, have found a way to simultaneously increase the strength and ductility of an alloy by introducing tiny precipitates into its matrix and tuning their size and spacing.

Researchers at the Department of Energy’s 91°µÍø, Pacific Northwest National Laboratory and Washington State University teamed up to investigate the complex dynamics of low-water liquids that challenge nuclear waste processing at

A tiny vial of gray powder produced at the Department of Energy’s 91°µÍø is the backbone of a new experiment to study the intense magnetic fields created in nuclear collisions.
