Mike Brady
When Oak Ridge National Laboratory researcher Mike Brady began his freshman year at Virginia Tech, he’d never heard of materials sciences. Now he’s a fellow of ASM International, the largest and most prestigious association of metals-centric materials scientists in the world. A na...
Michael Brady
Michael Brady, a materials scientist at the Department of Energy’s Oak Ridge National Laboratory, has been elected fellow of ASM International. ASM International, the world’s largest association of metals-centric scientists and engineers, honored Brady “for innov...
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...

2016 Billion-Ton Report

The 2016 Billion Ton Report, jointly released by the U.S. Department of Energy and Oak Ridge National Laboratory, concludes that the United States has the potential to sustainably produce at least 1 billion dry tons of nonfood biomass resources annually by 2040.

Simon Pallin

A scientist that sings opera and performs in musical theater? Sure. If you're a Renaissance Man like Simon Pallin. Pallin is a researcher in Oak Ridge National Laboratory’s Buildings Technologies Research & Integration Center. But his early interests and activities reveal a versatile person that could have chosen a number of occupations.

The image above shows the chain of the studied calcium isotopes. The “doubly magic” isotopes with mass numbers 40 (Ca-40) and 48 (Ca-48) exhibit equal charge radii. The first measurement of the charge radius in Ca-52 yielded an unexpectedly large result.

For decades nuclear physicists have tried to learn more about which elements, or their various isotopes, are “magic.” This is not to say that they display supernatural powers. Magic atomic nuclei are composed of “magic” numbers of protons and neutrons—collectively called nucleons—such as 2, 8, 20, and 28.

Temperature is represented by different colors for this heat sink for a 50-kilowatt DC-to-DC converter with red being the hottest.
Increased power densities in electronics will require more efficient heat sinks, and additive manufacturing combined with a simple thermal annealing process could help designers meet that goal. A team that includes Oak Ridge National Laboratory’s Tong Wu reported that while a 3-D printed aluminum alloy heat sink equaled or measured 10 percent worse than those manufactured conventionally, after the treatment the performance gap vanished.

Production run spot checks of materials for lithium-ion batteries and fuel cells could be a thing of the past because of a process developed at Oak Ridge National Laboratory. The infrared/thermal nondestructive evaluation technique invented by a team led by David Wood examines key parameters such as porosity and thickness of the coating in real time without destroying product.

Since the discovery of high-temperature superconductors — materials that can transport electricity with perfect efficiency at or near liquid nitrogen temperatures (minus-196 degrees Celsius) — scientists have been working to develop a theory that explains their essential physics.
After running a simulation proving calcium-48 was a magic isotope, ORNL researchers were surprised to find experimental data and simulations that suggested calcium-52 was not magic, as expected.
​A multi-institution team led by Oak Ridge National Laboratory’s Gaute Hagen used computation to corroborate experimental findings throwing calcium-52’s status as a magic isotope into question.
