David J. Dean has been named associate laboratory director for Physical Sciences at the Department of Energy's Oak Ridge National Laboratory, effective May 1. The Physical Sciences Directorate encompasses the laboratory's materials science and technology, chemic...
Researchers work on the delicate wiring of a cryostat, which is like a thermos under vacuum that chills the detectors that are the heart of the MAJORANA DEMONSTRATOR. The experiment’s 2 cryostats each house 29 germanium detectors—diodes that are reverse b
If equal amounts of matter and antimatter had formed in the Big Bang more than 13 billion years ago, one would have annihilated the other upon meeting, and today’s universe would be full of energy but no matter to form stars, planets and life. Yet matter exists now. ...

A new method to produce large, monolayer single-crystal-like graphene films more than a foot long relies on harnessing a “survival of the fittest” competition among crystals. The novel technique, developed by a team led by Oak Ridge National Laboratory, may open new opportunities for growing the high-quality two-dimensional materials necessary for long-awaited practical applications.

ACEAlloy cylinder: High-performance aluminum cerium alloys have automotive, aerospace and energy applications, such as this automotive cylinder head cast.

Four technologies developed at the Department of Energy’s Oak Ridge National Laboratory have earned 2018 Excellence in Technology Transfer Awards from the Federal Laboratory Consortium for Technology Transfer (FLC). The FLC is a nationwide network of more than 30...

Joseph Lukens, Pavel Lougovski and Nicholas Peters (from left), researchers with ORNL’s Quantum Information Science Group, are examining methods for encoding photons with quantum information that are compatible with the existing telecommunications infrast
A team of researchers led by the Department of Energy’s Oak Ridge National Laboratory has demonstrated a new method for splitting light beams into their frequency modes. The scientists can then choose the frequencies they want to work with and encode photons with qu...
The hCA II active site is flanked by hydrophilic (violet) and hydrophobic (green) binding pockets that can be used to design specific drugs targeting cancer-associated hCAs. Five clinical drugs are shown superimposed in the hCA II active site
New insights from neutron analysis of glaucoma drugs and their enzyme target may help scientists design drugs that more effectively target aggressive cancers. A team of researchers led by the Department of Energy’s Oak Ridge National Laboratory used neutro...
ORNL and EPRI built an enclosed welding system in a hot cell of ORNL’s Radiochemical Engineering Development Center. C. Scott White (ORNL) performs operations with remotely controlled manipulators and cameras.

Scientists of the Department of Energy’s Light Water Reactor Sustainability Program (LWRS) and partners from the Electric Power Research Institute (EPRI) have conducted the first weld tests to repair highly irradiated materials at DOE’s Oak Ridge National Laboratory.

A team led by the Department of Energy’s Oak Ridge National Laboratory has uncovered how certain soil microbes cope in a phosphorus-poor environment to survive in a tropical ecosystem. Their novel approach could be applied in other ecosystems to study various nutrient limitations and inform agriculture and terrestrial biosphere modeling.
ORNL’s Steven Young (left) and Travis Johnston used Titan to prove the design and training of deep learning networks could be greatly accelerated with a capable computing system.

A team of researchers from the Department of Energy’s Oak Ridge National Laboratory has married artificial intelligence and high-performance computing to achieve a peak speed of 20 petaflops in the generation and training of deep learning networks on the
