Researchers at the Statewide California Earthquake Center are unraveling the mysteries of earthquakes by using physics-based computational models running on high-performance computing systems at ORNL. The team’s findings will provide a better understanding of seismic hazards in the Golden State. 

ORNL’s Sholl elected to National Academy of Engineering

David Sholl, director of the Transformational Decarbonization Initiative at ORNL, has been elected a member of the National Academy of Engineering for his contributions in addressing large-scale chemical separation challenges, including carbon dioxide capture, using quantitative materials modeling.

ORNL researchers have developed a novel way to encapsulate salt hydrate phase-change materials within polymer fibers through a coaxial pulling process. The discovery could lead to the widespread use of the low-carbon materials as a source of insulation for a building’s envelope.

ORNL employees contributed over $828,000 to local nonprofits through the lab’s employee giving programs in 2023. ORNL’s managing contractor, UT-Battelle, provided an additional $139,600 in support of employee efforts. In addition, ORNL employees recorded over 1,497 volunteer hours, serving 56 nonprofits. With the value of these volunteer hours estimated at $36,232, total employee-led contributions for 2023 were valued at more than $1 million.
