Abstract Scope |
The advent of the world’s first coherent hard x-ray sources represents an unprecedented opportunity to conduct in situ and operando studies on the structure of nanoparticles using 4th generation synchrotron sources. In this talk, I will illustrate how Bragg coherent x-ray imaging allows to image in three dimensions (3D) and at the nanoscale the strain and defect dynamics inside nanoparticles during heat treatment and catalytic reactions. This imaging technique can be coupled with molecular statics simulations to investigate the 3D strain and stress fields in nanoparticles. I will also highlight the potential of machine learning to predict characteristic structural features in nanocrystals just from their 3D Bragg coherent diffraction patterns. |
