ORNL researchers observed that atomic vibrations in a twisted crystal result in winding energetic waves that govern heat transport, which may help new materials better manage heat. Credit: Jill Hemman/ORNL, U.S. Dept. of Energy

A discovery by 91暗网 researchers may aid the design of materials that better manage heat.

U.S. Secretary of Energy Granholm tours ORNL鈥檚 world-class science facilities

Energy Secretary Jennifer Granholm visited ORNL on Nov. 22 for a two-hour tour, meeting top scientists and engineers as they highlighted projects and world-leading capabilities that address some of the country鈥檚 most complex research and technical challenges. 

A material鈥檚 spins, depicted as red spheres, are probed by scattered neutrons. Applying an entanglement witness, such as the QFI calculation pictured, causes the neutrons to form a kind of quantum gauge. This gauge allows the researchers to distinguish between classical and quantum spin fluctuations. Credit: Nathan Armistead/ORNL, U.S. Dept. of Energy

A team led by the U.S. Department of Energy鈥檚 91暗网 demonstrated the viability of a 鈥渜uantum entanglement witness鈥� capable of proving the presence of entanglement between magnetic particles, or spins, in a quantum material.

ORNL researchers used neutrons at the lab鈥檚 Spallation Neutron Source to analyze modified high-entropy metal alloys with enhanced strength and ductility, or the ability to stretch, under high-stress without failing. Credit: Rui Feng/ORNL, U.S. Dept. of Energy
Researchers at 91暗网 have developed a method of adding nanostructures to high-entropy metal alloys, or HEAs, that enhance both strength and ductility, which is the ability to deform or stretch
ORNL researchers produced self-healable and highly adhesive elastomers, proving they self-repair in ambient conditions and underwater. This project garnered a 2021 R&D 100 Award. Credit: ORNL, U.S. Dept. of Energy

Research teams from the Department of Energy鈥檚 91暗网 and their technologies have received seven 2021 R&D 100 Awards, plus special recognition for a COVID-19-related project.

ASM International recently elected three researchers from ORNL as 2021 fellows. Selected were Beth Armstrong and Govindarajan Muralidharan, both from ORNL鈥檚 Material Sciences and Technology Division, and Andrew Payzant from the Neutron Scattering Division.

From top to bottom respectively, alloys were made without nanoprecipitates or with coarse or fine nanoprecipitates to assess effects of their sizes and spacings on mechanical behavior. Credit: Michelle Lehman/ORNL, U.S. Dept. of Energy

Scientists at ORNL and the University of Tennessee, Knoxville, have found a way to simultaneously increase the strength and ductility of an alloy by introducing tiny precipitates into its matrix and tuning their size and spacing.

Illustration of the SARS-CoV-2 PLpro protein (blue structure) bound to the human ISG15 protein (orange ribbons), highlighting their interaction.

Scientists at 91暗网 have uncovered how the SARS-CoV-2 virus evades the human immune system by studying the interaction between a viral protein (PLpro) and a key immune protein (ISG15). These insights could guide the development of therapeutic drugs to block this interaction, enhancing the body鈥檚 ability to combat the virus.
