  • Chlorite dismutase is a unique oxygen-generating enzyme that degrades chlorite, an industrial pollutant found globally in groundwater, drinking water and soils. Research conducted at ORNL contributes to a comprehensive structural and biochemical analysis of the enzyme, paving the way for future environmental applications.

  • Bacteria containing enzymes called beta-lactamases, illustrated by the light blue cluster, break down antibiotics and allow bacterial infections to develop and spread through human cells (orange). A team from ORNL’s Neutron Sciences Directorate is using neutrons to study how resistant bacteria, represented by the light blue rod shapes, are evolving to negate the effects of the beta-lactam class of antibiotics.

  • Paige Kelley uses the Four-Circle Diffractometer at HFIR to study ruthenium trichloride, obtaining its ordered moment size with the instrument’s unique capabilities. Kelley’s research could help lead to the realization of the qubit. Where bits represent either a 1 or 0 in conventional computing, qubits can achieve a mixed state called a superposition in which they are both 1 and 0 at the same time. This ability is critical to powering quantum computing. (Image credit: Genevieve Martin)
