Strain wave pathway to semiconductor-to-metal transition revealed by time-resolved X-ray powder diffraction. [PDF]

Nat Commun, 2021
One of the main challenges in ultrafast material science is to trigger phase transitions with short pulses of light. Here we show how strain waves, launched by electronic and structural precursor phenomena, determine a coherent macroscopic transformation

Structural Characterization of Pharmaceutical Cocrystals with the Use of Laboratory X-ray Powder Diffraction Patterns

Crystals, 2023
X-ray powder diffraction is a vital analytical tool that is used in pharmaceutical science. It is increasingly used to establish the crystal structure of a new pharmaceutical substance, in particular, cocrystal or its polymorphic forms.

“Everything's a sample”: Characterizing everyday materials using x-ray powder diffraction [PDF]

Structural Dynamics
We can learn something scientifically interesting about literally everything around us by examining it in a powder diffractometer. Comparing a macroscopic understanding of a material with the atomic-scale description proves to be a good way of generating

Fast X-ray powder diffraction on I11 at Diamond

Journal of Synchrotron Radiation, 2011
The commissioning and performance characterization of a position-sensitive detector designed for fast X-ray powder diffraction experiments on beamline I11 at Diamond Light Source are described. The detecting elements comprise 18 detector-readout modules of MYTHEN-II silicon strip technology tiled to provide 90° coverage in 2θ.
