Oak Ridge National Laboratory’s ongoing research in molten salt reactors—along with decades of renowned efforts in the field—is bringing nuclear experts together for its second workshop on the new generation of MSRs. The October 4-5 event is organized around the theme of “Moving MS...

General Mode KPFM uses advanced signal processing and analysis methods to extract local electronic properties directly from a noisy cantilever deflection signal.

Scientists at Oak Ridge National Laboratory are harnessing big data capture and analytics to quickly develop deep insight into materials and their dynamics. Their new technique builds on Kelvin probe force microscopy, long used to gather information about electronic properties by “...

Melissa Allen’s work at Oak Ridge National Laboratory is focused on urban infrastructure and atmospheric transport, creating models to determine the effects of temperature and climate changes on human activity.
Melissa Allen, a researcher at the Department of Energy's Oak Ridge National Laboratory, is guided by her curiosity and is inspired to pursue what she loves – music, flying and climate science. And she credits her family and many mentors who have helped her along the way. Gro...
Dianne Bull Ezell enjoys the variety of projects offered in a national laboratory setting.
Dianne Bull Ezell has always been a problem solver. As a child she built a bridge of Lego pieces for fun. Nowadays the Electrical & Electronics Systems Research Division engineer has grown from configuring toys to piecing together engineering solutions, and she’s still havin...
A new ORNL and 3M project will investigate ways to improve adhesive joining materials used in heating, ventilation, air conditioning and refrigeration systems.
Oak Ridge National Laboratory and 3M are teaming up to study whether adhesives can be developed to join heating, ventilation, air-conditioning and refrigeration components. Using neutron imaging capabilities at the lab’s High Flux Isotope Reactor, the research team will character...
Cleaning and maintaining solar mirrors could become less labor and time intensive with the application of ORNL-developed superhydrophobic coating technology.

Keeping energy-concentrating mirrors at solar thermal power plants free from dirt is both labor and time intensive. Researchers at Oak Ridge National Laboratory are working to address the challenge with lab-developed superhydrophobic coating technology. “We’ve shown that applying...

ORNL researchers use infrared photos to identify temperature loss that could create problems in the high-temperature fluoride salt pumped test loop.
Fluoride salt-cooled high-temperature reactors are a promising design in the next generation of nuclear energy production, and one of the first steps from concept to reality is underway at Oak Ridge National Laboratory. A team led by ORNL’s Graydon Yoder Jr. is operating a test l...
Bombarding a nickel lattice with high-energy neutrons creates a cascade of collisions that displace atoms. High-pressure energy waves generated early in the collision cascade determine the fate of defects that ultimately form in the material.

In nuclear reactors, energetic neutrons slam into metal atoms that are ordered in a lattice, displacing them with enough force to trigger a cascade of collisions. Laurent Béland, Yury Osetskiy and Roger Stoller, of the Energy Dissipation to Defect Evolution Energy Frontier Resear...

Emilio Ramirez studies the slugging transition in a bench scale reactor made possible by the Computational Pyrolysis Consortium, a multilaboratory collaboration formed to develop infrastructure ready fuel from biomass feedstock.

Just a few years ago, Emilio Ramirez spent his days operating and adjusting settings to optimize thermal performance at a Central California bioenergy power plant. Ramirez, a California native who is now a University of Tennessee doctoral candidate working with the Department of...
