The illustrations show how the correlation between lattice distortion and proton binding energy in a material affects proton conduction in different environments. Mitigating this interaction could help researchers improve the ionic conductivity of solid materials.

Ionic conduction involves the movement of ions from one location to another inside a material. The ions travel through point defects, which are irregularities in the otherwise consistent arrangement of atoms known as the crystal lattice. This sometimes sluggish process can limit the performance and efficiency of fuel cells, batteries, and other energy storage technologies.

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.

Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. These incidents occasionally have grave consequences, including burns, house fires and at least one plane crash.
