Like most scientists, Chengping Chai is not content with the surface of things: He wants to probe beyond to learn what’s really going on. But in his case, he is literally building a map of the world beneath, using seismic and acoustic data that reveal when and where the earth moves. Yet earthquakes are not the focus of Chai’s research at the Department of Energy’s Oak Ridge National Laboratory. He is using these waves to make waves — creating new opportunities for developing clean energy and enhancing sensing capabilities around nuclear reactors.

Oak Ridge National Laboratory researchers, in collaboration with Enginuity Power Systems, demonstrated that a micro combined heat and power prototype, or mCHP, with a piston engine can achieve an overall energy efficiency greater than 93%.

Stan David, retired scientist and Corporate Fellow Emeritus at the Department of Energy’s Oak Ridge National Laboratory, was awarded the Joining and Welding Science Award from the Joining and Welding Research Institute at Osaka University, Japan.

Rigoberto Advincula, a renowned scientist at the Department of Energy’s Oak Ridge National Laboratory and professor of Chemical and Biomolecular Engineering at the University of Tennessee, has won the Netzsch North American Thermal Analysis Society (NATAS) Fellows Award for 2023.

Nature-based solutions are an effective tool to combat climate change triggered by rising carbon emissions, whether it’s by clearing the skies with bio-based aviation fuels or boosting natural carbon sinks. At the Department of Energy’s Oak Ridge National Laboratory, scientists are leading research to transform plants into key drivers of decarbonization, from creating biomass crops for new fuels to enhancing the ability of plants to absorb and store carbon.

Oak Ridge National Laboratory joins four other national laboratories — Idaho, Los Alamos, Lawrence Livermore and Lawrence Berkeley — that have institutes named after nuclear chemist and Nobel Prize winner Glenn T. Seaborg.

As a biogeochemist at the Department of Energy’s Oak Ridge National Laboratory, Matthew Berens studies how carbon, nutrients and minerals move through water and soil. In this firsthand account, Berens describes recent fieldwork in Louisiana with colleagues to better understand key processes in coastal ecosystems.

ORNL’s electromagnetic isotope separator, or EMIS, made history in 2018 when it produced 500 milligrams of the rare isotope ruthenium-96, unavailable anywhere else in the world. And EMIS technology just keeps getting better, said Brian Egle, who heads the Enrichment Science and Engineering Division’s Stable Isotope Research, Development and Production Section. “It’s capable of, essentially, separating the whole periodic table,” he said.

Tomonori Saito, a distinguished innovator in the field of polymer science and senior R&D staff member at the Department of Energy’s Oak Ridge National Laboratory, was honored on May 11 in Columbus, Ohio, at Battelle’s Celebration of Solvers.
