Understanding how ions diffuse in solid materials is essential for technologies including batteries, electronics and chemical catalysts, but it has been hard for a simple reason: the materials are solids.
A research team has developed a new theoretical framework that can suppress light scattering in certain directions while enhancing it in others, even in irregularly arranged materials. The work extends research on controlling light scattering, which has traditionally centered on ordered crystal ...
