research papersSingle-shot X-ray imaging of two-dimensional strain fields in colloidal crystals
We used the Bragg coherence diffraction imaging method at the Coherent Scattering and Imaging endstation of the Shanghai Soft X-ray Free Electron Laser Facility to characterize colloidal crystals. This method successfully reproduced the static shape of crystals and we observed the defect structure of colloidal samples.
research papersAccounting for electron-beam-induced warping of molecular nanocrystals in MicroED structure determination
Here we identify and characterize the warping of molecular crystal lattices induced by electron beam exposure during microcrystal electron diffraction (MicroED/3DED) data collection. We find changes to consensus crystal lattice orientation that are often dramatic, and appear ubiquitous in small organic molecule crystals. This evidence highlights the relevance of crystal bending or warping as a consequence of radiation-induced damage on molecular specimens, and points to it as a fundamental source of error in MicroED/3DED data collection and structure determination.
