Joe Paddison, a Eugene P. Wigner Fellow at the Department of Energy’s Oak Ridge National Laboratory, believes there’s more information to be found in neutron scattering data than scientists like himself might expect.

To understand the electronic structures of solids and predict their properties, ORNL’s Valentino Cooper uses density functional theory (DFT), which models how many electrons are in a region rather than where those electrons are. “DFT essentially presents one electron existing in a ‘sea foam’ and tells how dense that foam is,” he said.

Scanning probe microscopes use an atom-sharp tip—only a few nanometers thick—to image materials on a nanometer length scale. The probe tip, invisible to the eye, is attached to a cantilever (pictured) that moves across material surfaces like the tone arm on a record player.

Organic chemist Santa Jansone-Popova designs new chemical architectures to support chemical separations that lay the groundwork for clean water and energy advances.

An organic chemist at Oak Ridge National Laboratory, Santa Jansone-Popova focuses on the fundamental challenges of chemical separations that translate to world-changing solutions for clean water and sustainable energy.

Bruce Moyer’s 40-year career as a chemist at Oak Ridge National Laboratory has advanced the nation’s nuclear, environmental, and clean energy solutions across decades with basic-to-applied research in chemical separations.

Bruce Moyer’s career as a trailblazing chemist began with a Gilbert chemistry set, the perfect Christmas gift for an inquisitive kid growing up in 1960s Pennsylvania. Moyer squirreled away the test tubes and racks of chemicals in his bedroom to conduct unsupervised experiments on solubility, corrosion, and other subjects included in Gilbert’s captivating manual.
