3D rendering of a polymer chain with embedded ions on a black background.

Researchers at ORNL 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. 

Illustration of waste-to-energy cycle showing trash converted into fuel and electricity powering a car and factory.

Researchers at ORNL 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. If scaled beyond the laboratory, the process could strengthen U.S. energy security and industrial competitiveness.

Researchers at ORNL have invented a reusable adhesive from waste polymers that is tougher than commercial glues, works underwater as well as in dry environments, and bonds a variety of materials. Inspired by the way mussels stick to surfaces, the innovative adhesive contains reversible chemical crosslinkers that allow the hardened glue to soften, detach and be reused.

A close-up of a laboratory experimental setup showing a cylindrical metal vacuum chamber with a circular optical viewport emitting bright blue light. A FLIR camera and optical sensors are mounted on an aluminum rail aimed at the glowing chamber interior. The viewport is surrounded by bolts and insulation straps, and a hinged metal mesh cover is open to the right, revealing the illuminated interior used for diagnostics or plasma experiments.

Researchers at ORNL are helping to enable the next generation of abundant, affordable nuclear energy by combining 80 years of know-how with the latest scientific techniques, facilities and equipment. The lab’s longstanding expertise in degradation of materials in the harsh environments of nuclear reactors make it the go-to place for a resurgence of interest in liquid metals and molten salts for both advanced fission and fusion reactors. 

Two researchers stand in a laboratory with advanced analytical instruments, including a laser ablation system and an inductively coupled plasma mass spectrometer. The man on the left is wearing glasses, a green shirt, and khaki pants, while the woman on the right is wearing a black top and khaki pants with her arms crossed.

ORNL's Sarah Szakas and Hunter Andrews were named among the world’s top young analytical scientists. The recognition came in a special issue of the Journal of Analytical Atomic Spectrometry, a Royal Society of Chemistry publication that shares innovative research on the fundamental theory and application of spectrometric techniques.

ORNL researcher Bruce Moyer is posing for a photo with a brown jacket and blue background

Chemist Bruce Moyer, a Corporate Fellow at the Department of Energy’s Oak Ridge National Laboratory, has won the 2025 Carl Hanson Award, the highest international recognition for achievement in solvent extraction. The International Solvent Extraction Community bestows the medal every three years based on nominations from the global community.

A visualization showing a quantum computing system connected to classical supercomputing infrastructure. On the left, a cryogenic quantum processor is suspended within a metal frame, linked by golden cables to nearby electronics and control units. These control units are connected to several large black server racks on the right, representing a hybrid quantum–classical computing environment. The image highlights the data flow and integration between quantum hardware and classical computing resources.

ORNL, NVIDIA, and HPE are partnering to integrate quantum computing, AI, and high-performance computing using NVIDIA NVQLink and CUDA-Q, establishing a hybrid testbed at ORNL to advance quantum–classical convergence and scientific discovery.
