This Zenodo entry is comprised of the following datasets: 1. The folder '3D_ED_data.zip" contains raw 3D electron diffraction (3D ED) data as output by Instamatic. Its contents include an instrument log file (cRED_log.txt), as well as a folder with diffraction frames in formats compatible with processing using either REDp (.mrc) and XDS (.smv), along with the appropriate input files. The folder also contains a folder of defocused diffraction frames showing the orientation of the crystal with respect to the selected area aperture throughout the data collection. 2. The folder "STEM.zip" contains scanning transmission electron microscopy images of cross-sectioned SU-102 crystals. The EMD file contains the images in the native Thermo Fischer format. TIF files of the individual images are also provided. 3. The folder "Lab-scale_EOC_removal.zip" contains the data points for the lab-scale adsorption/photodegradation studies of atenolol, diclofenac, and sulfamethazine using the zirconium ellagate SU-102.
