A new technical paper titled “Interface sharpness in stacked thin film structures: a comparison of soft X-ray reflectometry and transmission electron microscopy” was published by researchers at ...

Lasing is much more difficult at X-ray frequencies than with visible light. The conditions that enable electrons in an atom to stay at sufficiently high energy levels to produce an X-ray laser cannot ...

For the first time, researchers can study the microstructures inside metals, ceramics and rocks with X-rays in a standard laboratory without needing to travel to a particle accelerator, according to ...
