Researchers at Oak Ridge National Laboratory and collaborators found a new way to control how heat moves through certain ceramic materials. By applying an electric field, they changed the behavior of tiny vibrations in the material (called phonons), making heat travel much more easily in the direction of the field—nearly tripling thermal conductivity compared with other directions. The discovery could help create solid-state devices that manage heat more efficiently in electronics, energy systems and other technologies.

Separated by an ocean and more than a decade, innovative experiments with 31 tin isotopes having either a surplus or shortage of neutrons show how neutrons influence nuclear stability and element formation. The experiments, conducted between 2002 and 2012 at Oak Ridge National Laboratory and more recently at CERN, provide knowledge that impacts nuclear energy and national security applications.

Food scraps, manure and sewage are natural byproducts of the U.S. agricultural industry. They are also rich in biogas, a mixture that contains methane and other valuable chemicals. A team of researchers at Sandia National Laboratories are developing chemistry that could help capture methane from biogas and separate it from other gases so it can be put to good use.

Using the Frontier supercomputer at the Department of Energy’s Oak Ridge National Laboratory, researchers from the Georgia Institute of Technology have performed the largest direct numerical simulation (DNS) of turbulence in three dimensions, attaining a record resolution of 35 trillion grid points.

A paper published in Nature Communications shows how AI at Sandia National Laboratories is advancing beyond a mere automation tool toward becoming a powerful engine for clear, comprehensible scientific discovery.

Neuromorphic computers, inspired by the architecture of the human brain, are proving surprisingly adept at solving complex mathematical problems that underpin scientific and engineering challenges.

In collaboration with chemical technology and engineering company Dimensional Energy, scientists at the U.S. Department of Energy’s Oak Ridge National Laboratory have integrated binder jet additive manufacturing with an advanced post-processing method to fabricate leak-tight ceramic components, overcoming a key challenge of ceramic additive manufacturing. 

Oak Ridge National Laboratory (ORNL) researchers have overcome a barrier to using a more affordable, dry process for manufacturing the lithium-ion batteries used in vehicles and electronic devices. The resulting batteries provide greater electricity flow and reduced risk of overheating.

Researchers at the U.S. Department of Energy (DOE)’s Oak Ridge National Laboratory (ORNL) have developed an innovative new technique using carbon nanofibers to enhance binding in carbon fiber and other fiber-reinforced polymer composites – an advance likely to improve structural materials for automobiles, airplanes and other applications that require lightweight and strong materials.
