Let’s Get Small: New Argonne Method Greatly Improves X-Ray Nanotomography Resolution

It’s been a truth for a long time: if you want to study the movement and behavior of single atoms, electron microscopy can give you what X-rays can’t. X-rays are good at penetrating into samples — they allow you to see what happens inside batteries as they charge and discharge, for example — but historically they have not been able to spatially image with the same precision that electrons can.
