Science Highlights

Researchers at the Department of Energy’s Oak Ridge National Laboratory and their collaborators used lasers and neutrons to observe a long-lived quantum state in a magnetic material, opening a new way to study materials systems driven far from their equilibrium. Manipulation of quantum magnets is important for advancing quantum information science and could reduce loss of transported information, improve memory devices and benefit other quantum technologies.

Researchers at Oak Ridge National Laboratory have developed SimuScan, an AI system that helps an atomic force microscope — a tool that maps surfaces at the scale of molecules — recognize meaningful features and decide where to look next. Trained on realistic, simulated images, it can reduce the need for expert manual control and make nanoscale imaging faster, more consistent, and better suited for automated, high-throughput research.

Oak Ridge National Laboratory researchers developed an artificial intelligence system that can manipulate individual molecules to build custom materials with atomic precision. The approach could eventually allow scientists to specify desired electronic properties and use AI to help create materials tailored for advanced electronics, memory technologies and quantum computing.

Oak Ridge National Laboratory researchers have uncovered a path to design superionic polymer electrolytes for solid-state batteries and other energy applications that could help ensure a future of abundant and reliable energy for the United States. The scientists demonstrated that by carefully controlling the chemical composition of a lithium salt-based polymer, they could create a material that enables superfast transport of ions in batteries and many other energy storage and conversion technologies.

Researchers at the Department of Energy’s Oak Ridge National Laboratory developed a method to convert a commonly discarded hydrocarbon polymer into gasoline- and diesel-like fuels. The team has applied for a patent for the discovery, which treats polyethylene — the stuff of white cutting boards and shopping bags — with aluminum chloride-containing molten salts that serve as both solvent and catalyst. The results were published in the Journal of the American Chemical Society.

Researchers at the Department of Energy’s Oak Ridge National Laboratory have advanced the knowledge required to improve large-scale energy storage. In doing so, they have revealed distinct chemical reactions that improve the stability and efficiency of a promising energy-storage system. Their findings suggest positive implications for U.S. energy security, including increased national power grid reliability and affordability.
