When Christi Johnson finishes clocking an eighth of a mile in 4.7 seconds, she jumps out of the dagger-shaped drag racer while its wheels are still smoking, pulls off her helmet… and the next morning, pulls on her lab coat.

As a technical professional at the Department of Energy’s Oak Ridge National Laboratory, Johnson has developed, built and tested hardware and software for innovations including a jet blast deflector, an ultrasonic dryer, a sensor system for driver recognition and waveguide inspection tubes for the world’s largest magnetic fusion device. But Johnson, who works in the Multimodal Sensor Analytics Group, said her scientific career really began when she was a little girl eager for her turn in a fast car.

Scientists at Oak Ridge National Laboratory have advanced the use of DuAlumin-3D, an innovative aluminum alloy, in high-temperature automotive components, significantly expanding the possibilities of additive manufacturing.

Research using neutrons at Oak Ridge National Laboratory’s High Flux Isotope Reactor is helping scientists better understand how to extract oil from unconventional reservoirs, serving to reinforce America’s energy independence.

Oak Ridge National Laboratory’s Peregrine software, used to monitor and analyze parts created through powder bed additive manufacturing, has released its most advanced dataset to date.

Researchers at Berkeley Lab used the Frontier supercomputer at Oak Ridge National Laboratory to develop the most advanced simulations to date for studying earthquake dynamics. The simulations reveal in stunning new detail how geological conditions influence earthquake intensity — and, in turn, how those complex ground motions directly impact buildings and infrastructure. The data is already being shared with the broader earthquake science and engineering communities to deepen understanding of seismic behavior and to guide the designs of earthquake-resistant infrastructure and improved emergency response.

Vinit Chaudhary, founder of Elemental Composites and a member of Cohort 2024 in the Innovation Crossroads program, comes from a family of entrepreneurs and has long been interested in business. Supported by Innovation Crossroads — a Department of Energy Lab-Embedded Entrepreneurship Program node at Oak Ridge National Laboratory — Chaudhary is developing natural fiber composites that are strong, lightweight, and biodegradable. This innovative approach is designed to reduce waste, create new markets for farmers and expand the use of alternative materials across industries such as transportation, automotive, marine infrastructure and sporting goods.

Researchers at the Department of Energy’s Oak Ridge National Laboratory are breaking technical barriers with faster circuit breakers to enable and protect the modern electric grid. The ORNL team developed medium-voltage circuit breakers capable of handling increasing levels of direct current at a lower cost, an advance that can help reduce future electricity costs and expand capacity in an overburdened U.S. grid. 

From the world of research papers and cubicles, Kevin Roccapriore has made a leap into the entrepreneurial arena with Innovation Crossroads, a Lab-Embedded Entrepreneurship Program node at the Department of Energy’s Oak Ridge National Laboratory that provides support for startups like Roccapriore’s AtomQ. 

In a bold step toward transforming how nuclear infrastructure is built, the Department of Energy’s Manufacturing Demonstration Facility, or MDF, at Oak Ridge National Laboratory, in partnership with Kairos Power and Barnard Construction, has successfully developed and validated large-scale, 3D-printed polymer composite forms for casting complex, high-precision concrete structures that would be technically challenging and costly to produce using conventional methods. 

Researchers at Oak Ridge National Laboratory have successfully 3D printed steel capsules that withstood rigorous testing inside a nuclear reactor — a first-of-its-kind achievement. Using advanced manufacturing techniques and AI-driven design, the team produced capsules that maintained integrity under irradiation. This breakthrough shortens the timeline for developing and qualifying new materials for nuclear energy, accelerating innovation and strengthening energy security.
