Nuclear@PNNL: Cation Effects on Radicals from Nitrite | International Glass Corrosion Workshop

Cation Effects on Radicals from Nitrite

Solutions of nitrite ions, when exposed to radiation, form a diverse range of radicals. These radicals participate in a wide range of chemical reactions, affecting the overall composition of a solution. Researchers studied how varying a metal cation altered the formation of nitrite-derived radicals in highly concentrated solutions. They found that the nature of the cation had a significant effect on the production of radicals under ultraviolet irradiation. Read More.

New AI Model Is a Leap for Autonomous Materials Science

Materials science enables cutting-edge technologies, from lightweight cars and powerful computers to high-capacity batteries and durable spacecraft. But to develop materials for these applications, they need to be exactingly analyzed through numerous microscopic lenses—a difficult and time-consuming process. A new artificial intelligence model developed at PNNL can identify patterns in electron microscope images of materials without requiring human intervention, allowing for more accurate and consistent materials science.
