Grant and Award Announcement

Georgia Tourassi of Oak Ridge National Laboratory's Computing and Computational Sciences Directorate has received the ORNL Director's Award for Outstanding Individual Accomplishment in Science and Technology.

Neutrons improve weld integrity of underwater wind turbine foundations

DOE/Oak Ridge National Laboratory

Massive offshore structures like oil rigs and wind turbines are designed to withstand the myriad punishments oceans tend to mete out. However, over time, just the saltwater itself can significantly decrease the durability of a structure's welds. That's why researchers are using neutron analysis at ORNL's HFIR to validate a more advanced method of welding involving high-power lasers.

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

DOE/Oak Ridge National Laboratory

Paige Kelley, a postdoctoral researcher with a joint appointment at the University of Tennessee and the Department of Energy's Oak Ridge National Laboratory, is using neutrons to study specific crystal properties that could lead to the realization of a quantum spin liquid, a novel state of matter that may form the basis of future quantum computing technologies.

Two ORNL-led research teams receive $10.5 million to advance quantum computing for science

DOE/Oak Ridge National Laboratory
Grant and Award Announcement

DOE's Office of Science has awarded two research teams, each headed by a member of ORNL's Quantum Information Science Group, more than $10 million over 5 years to both assess the feasibility of quantum architectures in addressing big science problems and to develop algorithms capable of harnessing the massive power predicted of quantum computing systems. The two projects are intended to work in concert to ensure synergy across DOE's quantum computing research spectrum and maximize mutual benefits.

Researchers customize catalysts to boost product yields, decrease separation costs

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

For some crystalline catalysts, what you see on the surface is not always what you get in the bulk, according to two studies led by the Department of Energy's Oak Ridge National Laboratory. The investigators discovered that treating a complex oxide crystal with either heat or chemicals caused different atoms to segregate on the surface, i.e., surface reconstruction. Those differences created catalysts with dissimilar behaviors, which encouraged different reaction pathways and ultimately yielded distinct products.

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

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Scientists at the Department of Energy's Oak Ridge National Laboratory have performed neutron structural analysis of a vitamin B6-dependent protein, potentially opening avenues for new antibiotics and drugs to battle diseases such as drug-resistant tuberculosis, malaria and diabetes. Specifically, the team used neutron crystallography to study the location of hydrogen atoms in aspartate aminotransferase, or AAT, an enzyme vital to the metabolism of certain amino acids.

Spin current detection in quantum materials unlocks potential for alternative electronics

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

A new method that precisely measures the mysterious behavior and magnetic properties of electrons flowing across the surface of quantum materials could open a path to next-generation electronics. A team of scientists has developed an innovative microscopy technique to detect the spin of electrons in topological insulators, a new kind of quantum material that could be used in applications such as spintronics and quantum computing.

Connecting the dots

DOE/Oak Ridge National Laboratory

Nuclear physicists at the Department of Energy's Oak Ridge National Laboratory and their partners are using America's most powerful supercomputers to characterize the behavior of objects, from subatomic neutrons to neutron stars, that differ dramatically in size yet are closely connected by physics. Through the DOE Office of Science's Scientific Discovery through Advanced Computing program, which concurrently advances science and supercomputing to accelerate discovery, ORNL is participating in two five-year computational nuclear physics projects.
