X rays Measure Lone Molecules

X rays Measure Lone Molecules | Physics | Scoop.it
Researchers measured an atomic distance in a molecule without using a crystal, which is usually required. Instead they used a beam of isolated molecules.
Mikko Hakala's insight:

This is a great demonstrations how x-ray free electron lasers are used for diffraction imaging of single molecules.

Faster X-ray technology observes catalyst surface at work with atomic resolution

Faster X-ray technology observes catalyst surface at work with atomic resolution | Physics | Scoop.it
By using a novel X-ray technique, researchers have observed a catalyst surface at work in real time and were able to resolve its atomic structure in detail. The new technique, pioneered at DESY's X-ray light source PETRA III, may pave the way for the design of better catalysts and other materials on ...
Mikko Hakala's insight:

High-energy X-ray diffraction is reported as an advantageous imaging technique for surface atomic structures. It can be used at realistic, in situ dynamical conditions (in real time).
