  • Researcher Rob Schmidt and his team are using neutrons at HFIR’s CG-1D imaging instrument to study the development of dendrites with hope of improving the design of next-generation lithium ion batteries. Dendrites are thin microscopic fibers that can carry electrical current inside lithium batteries and, in some cases, cause safety and reliability issues. (Image credit: ORNL/Genevieve Martin)
    Testing Lithium Battery Limitations May Improve Safety and Lifetimes
  • The Weyl semimetal state is induced when the opposing motions of the electrons cause the Dirac cones to split in two (illustrated on the left by outward facing electrons, opposite the inward facing electrons on the right). The abnormal state enables greater electrical flow with minimal resistance. (Image credit: ORNL/Jill Hemman)
    Neutrons Reveal the Wild Weyl World of Semimetals
  • ORNL researchers Todd Toops, Charles Finney, and Melanie DeBusk (left to right) hold an example of a particulate filter used to collect harmful emissions in vehicles. Using neutrons, they are cultivating a better understanding of how heat treatments and oxidation methods can remove layers of soot and ash from these filters, which could lead to improved fuel efficiency.

  • Researchers from Washington University in St. Louis and ORNL are using neutrons to study what happens when cyanobacteria cell samples (pictured) are starved for nitrogen. They are especially interested in how this process affects phycobilisomes, large antenna protein complexes in the cells that harvest light for photosynthesis. A better understanding of this natural phenomenon could lead to improvements in artificial resources like solar panels. (Image credit: ORNL/Genevieve Martin)
    Cyanobacterial Studies Examine Cellular Structure During Nitrogen Starvation
  • 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.
