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

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...

Chaitanya Narula led analysis of an ORNL biofuel-to-hydrocarbon conversion technology to explain the underlying process.

A new study from the Department of Energy’s Oak Ridge National Laboratory explains the mechanism behind a technology that converts bio-based ethanol into hydrocarbon blend-stocks for use as fossil fuel alternatives. Scientists have experimented for decades with a cl...

The next-generation Earth system model will simulate climate systems at unprecedented resolution over an unprecedented time scale in order to understand climate change, Earth system feedbacks and potential tipping points. The Accelerated Climate Model for Energy project, led...
Conceptual art connects the atomic underpinnings of the neutron-rich calcium-48 nucleus with the Crab Nebula, which has a neutron star at its heart. Zeros and ones depict the computational power needed to explore objects that differ in size by 18 orders o
An international team led by Gaute Hagen of the Department of Energy’s Oak Ridge National Laboratory used America’s most powerful supercomputer, Titan, to compute the neutron distribution and related observables of calcium-48

High-resolution imaging of materials produces complex, copious data. Researchers at Oak Ridge National Laboratory are developing a visual analytics system that could essentially “look over a scientist’s shoulder,” learning from human actions and improving its predictions of ...
In complex alloys, chemical disorder results from a greater variety of elements than found in traditional alloys. Traces here indicate electronic states in a complex alloy; smeared traces reduced electrical and thermal conductivity. Image credit: Oak Ridg
Designing alloys to withstand extreme environments is a fundamental challenge for materials scientists. Energy from radiation can create imperfections in alloys, so researchers in an Energy Frontier Research Center led by the Department of Energy’s Oak Ridge National ...
An ORNL technology that converts waste rubber into a valuable energy storage material has been licensed to RJ Lee Group. ORNL inventors Amit Naskar (left) and Parans Paranthaman flank Richard Lee, CEO of RJ Lee Group.
RJ Lee Group has signed an agreement to license an invention developed at the Department of Energy’s Oak Ridge National Laboratory that converts waste rubber into a valuable energy storage material. The technology turns rubber sources such as tires into carbon blac...
Redistribution of electronic clouds causes a lattice instability and freezes the flow of heat in highly efficient tin selenide. The crystal lattice adopts a distorted state in which the chemical bonds are stretched into an accordion-like configuration, an

Engines, laptops and power plants generate waste heat. Thermoelectric materials, which convert temperature gradients to electricity and vice versa, can recover some of that heat and improve energy efficiency. A team of scientists at the Department of Energy’s Oak Ridg...
