Structural Dynamics, Vol 3, Iss 5, Pp 054304-054304-8 (2016)

We present an X-ray-optical cross-correlator for the soft (> 150 eV) up to the hard X-ray regime based on a molybdenum-silicon superlattice. The cross-correlation is done by probing intensity and position changes of superlattice Bragg peaks caused by

Publikováno v: Crystals, Vol 10, Iss 725, p 725 (2020)

The parallel advances of different scientific fields provide a contemporary scenario where collaboration is not a differential, but actually a requirement. In this context, crystallography has had a major contribution on the medical sciences, providi
