Novel method improves the resolution of hard X-ray nanotomography

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 electrons can.
