In situ neutron diffraction visualizes the synthesis mechanism, involving multi-phase evolutions, of garnet-type fast lithium-ion solid conductors. The neutron diffraction determines the lithium vacancy distribution in the garnet lattice, and reveals the
Although they don’t currently have as much conductivity, solid-state electrolytes designed for lithium-ion batteries (LIBs) are emerging as a safer alternative to their more prevalent—sometimes flammable—liquid-electrolyte counterparts. However, a new study conducted at Oak Ridg...
The Roane State Community College associates are (from left) Jeff Manning, Chris Zerr, Bruce Lester, Joe Pyle, Darrell Roddy and Rusty Dryman.

Bruce Lester has had a lot of jobs: fisherman, horse trainer, “professional stair builder.” He last worked for a real estate company, surveying land using geographic software. “When the bottom fell out of the construction industry and the company downsized, I got laid off,” 

ORNL researchers (from left) Seung-Hwan Lim, Larry Roberts, Sreenivas Rangan Sukumar and Matt Lee developed a new smart data tool for medical research called ORiGAMI that has the potential to accelerate medical research and discovery.
As medical research has become more specialized, the scientific community’s understanding of the human body has increased, resulting in enhanced treatments, new drugs, and better health outcomes. A side effect of this information explosion, however, is the fragmentation of know...

A new freight database developed with assistance from the Department of Energy’s Oak Ridge National Laboratory will help transportation officials improve highways, railroads and other trade routes across the country. With funding from the Department of Transportation’s Bureau of T...

Using high-performance computing, ORNL researchers are modelling the atomic structure of new alloys to select the best candidates for physical experimentation.

The Department of Energy’s Oak Ridge National Laboratory, FCA US LLC, and the foundry giant, Nemak of Mexico, are combining their strengths to create lightweight powertrain materials that will help the auto industry speed past the technological

More than 200 scientists from around the world assembled October 27 to 29 at the Department of Energy’s Oak Ridge National Laboratory to provide input on the scientific instruments that would be installed at a proposed Second Target Station (STS) at the Spallation Neutron Source (SNS). ...
Take a Periscope tour of America's fastest supercomputer

Oak Ridge National Laboratory gave social media users an exclusive tour of its supercomputer Titan on Nov. 5. Using Periscope, a live video broadcasting service app, Bronson Messer, senior scientist at ORNL's Scientific Computing and Theoretical Physics Groups...

Advances in ultrathin films have made solar panels and semiconductor devices more efficient and less costly, and researchers at the Department of Energy’s Oak Ridge National Laboratory say they’ve found a way to manufacture the films more easily, too. Typically the films—used b...
Alvin Weinberg, then the director of Oak Ridge National Laboratory, marks 6000 power hours performance of his brainchild, the Molten Salt Reactor Experiment, in October 1967.

The Molten Salt Reactor Experiment (MSRE), which ran a brief four years in the 1960s but earned an enduring legacy as an innovative reactor technology concept, this year marks a half century since its June 1965 startup. A workshop on molten salt reactor technologies, "From the ...
