ORNL’s Huiyuan Zhu places a sample of boron nitride, or “white graphene,” into a furnace as part of a novel, nontoxic gas exfoliation process to separate 2D nanomaterials.
A team of scientists led by the Department of Energy’s Oak Ridge National Laboratory has developed a novel way to produce two-dimensional nanosheets by separating bulk materials with nontoxic liquid nitrogen. The environmentally friendly process generates a 20-fold ...
ORNL's Holifield Radioactive Ion Beam Facility.
The American Physical Society (APS) on Monday honored the Holifield Radioactive Ion Beam Facility, located at the Department of Energy's Oak Ridge National Laboratory, as an APS Historic Physics Site. The APS is one of the world's top professional societies for s...

Sitting in the driver’s seat comes naturally to Ron Graves, the recently retired head of Oak Ridge National Laboratory’s sustainable transportation program. Graves has logged more than 100 days on national racetracks like Daytona, Road Atlanta, and Pocono where he routinely reache...

ORNL software engineer Eric Lingerfelt (right) and Stephen Jesse (left) of ORNL’s Center for Nanophase Materials Sciences led the development of the Bellerophon Environment for Analysis of Materials (BEAM).
Using today’s advanced microscopes, scientists are able to capture exponentially more information about the materials they study compared to a decade ago—in greater detail and in less time. While these new capabilities are a boon for researchers, helping to answer key quest...
Andrew King loads a gel with amplified gene fragments to detect the presence of mercury methylation genes in samples from East Fork Poplar Creek in Oak Ridge.

Environmental scientists can more efficiently detect genes required to convert mercury in the environment into more toxic methylmercury with molecular probes developed by researchers at the Department of Energy’s Oak Ridge National Laboratory. “We now have a quic...

This 3-D structure was created in a microscope. On the left is the structure; on the right is the simulation that shows how to create such a structure.

Additive manufacturing techniques featuring atomic precision could one day create materials with Legos flexibility and Terminator toughness, according to researchers at the Department of Energy’s Oak Ridge National Laboratory. In a review paper published in ACS Nano, Olga Ovchinni...
