Ada Sedova, a postdoctoral research associate at the Oak Ridge Leadership Computing Facility (OLCF), develops computational calculations for supercomputing codes. In front of the OLCF’s Titan supercomputer, Sedova displays a spectrum from her experimental work, measuring the vibrational frequency of nucleobases (bases of DNA and RNA) at the Spallation Neutron Source, and complementary computational calculations.

OLCF Postdoc Fuses the Gap Between Experiment and Computation

Neutrons Improve Weld Integrity of Underwater Wind Turbine Foundations

Neutrons observe vitamin B6-dependent enzyme activity useful for drug development

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

Neutrons reveal suppression of magnetic order in pursuit of a quantum spin liquid

Researchers from the DOE Manufacturing Demonstration Facility located at ORNL used neutrons to test residual stress in 3D-printed steel parts. By studying complex geometries like the figure 6 shown here, researchers can design and build more complex structures with large-scale 3D metal printing.

Joint user meeting brings bright future for ORNL neutrons and nanosciences

$With the help of other researchers from ORNL and Colorado State University, Daniel Olds and Katharine Page developed a U-tube gas flow cell to study catalysts and better understand how they facilitate chemical reactions. With this cell integrated into a new sample environment, they can combine neutron diffraction and isotope analysis techniques to view catalytic behavior under realistic operating conditions.
