DIOPTAS: a program for reduction of two-dimensional X-ray diffraction data and data exploration
TL;DR: Dioptas is a Python-based program for on-the-fly data processing and exploration of two-dimensional X-ray diffraction area detector data, specifically designed for the large amount of data collected at XRD beamlines at synchrotrons.
Journal ArticleDOI
Synthesis of clathrate cerium superhydride CeH9 at 80-100 GPa with atomic hydrogen sublattice.

TL;DR: It is shown that CeH9 can be synthesized at 80-100 GPa with laser heating, and is characterized by a clathrate structure with a dense 3-dimensional atomic hydrogen sublattice, which shed a significant light on the search for superhydrides in close similarity with atomic hydrogen within a feasible pressure range.
Journal ArticleDOI
