It’s been more than three decades since inventor Chuck Hull created stereolithography, a process that produces 3D objects by hardening a liquid resin with an ultraviolet laser beam.

Devices using this process, widely considered the first 3D printers, are still in use today, but they are hardly al...

ORNL is proud of its role in fostering the next generation of scientists and engineers. We bring in talented young researchers, team them with accomplished scientists and engineers, and put them to work at the lab’s one-of-a-kind facilities. The result is research that makes us proud and prepares th...

Caltech chemical engineer Frances Arnold delivered the Eugene P. Wigner Distinguished Lecture in Science, Technology, and Policy at ORNL on Nov. 2, 2015.

ORNL’s Molten Salt Reactor Experiment operated more than 13,000 hours during its four-year run in the mid- to late 1960s. A priority of long-serving lab director Alvin Weinberg, MSRE was noteworthy at least in part because it ran on fuel that circulated through the reactor rather than staying put in...

A global agreement to phase down the use of potent greenhouse gas refrigerants and replace them with climate-friendly alternatives leaned on multiple ORNL studies. In a landmark decision, climate leaders from more than 190 countries agreed to amend the Montreal Protocol to discontinue producing a...

Extreme pressure can lead to chemical compounds not found on Earth under normal conditions. Nobel Prize winner Roald Hoffmann discusses how they can give us valuable information.

ORNL researchers are turning a physical oddity into cleaner, cheaper appliances.
