SU-102: Raw Electron Diffraction, Microscopy, and Adsorption Data

Stockholm University provides a multi-modal dataset for the zirconium ellagate material SU-102. It contains raw 3D electron diffraction frames, scanning transmission electron microscopy images of cross-sectioned crystals, and tabular data from lab-scale adsorption and photodegradation studies of pharmaceutical contaminants. The data supports research in materials characterization and environmental remediation.

Use Cases

• Processing 3D electron diffraction data based on raw .mrc and .smv frame files.
• Analyzing crystal morphology and defects based on scanning transmission electron microscopy images in .emd and .tif formats.
• Modeling adsorption kinetics of pharmaceuticals based on lab-scale removal data points for atenolol, diclofenac, and sulfamethazine.

Strengths

• Contains raw, unprocessed 3D electron diffraction data, providing a foundation for independent structural analysis.
• Includes data in multiple specialized formats (.mrc, .smv, .emd) compatible with standard processing software like REDp and XDS.
• Combines structural characterization data (diffraction, microscopy) with functional performance data (contaminant removal) for the same material.

Limitations

• Key metadata such as dataset size, row counts, and specific column names are not provided across all sources.
• The last update date is unknown, limiting assessment of data freshness.
• The dataset is a collection of three distinct archives, which may require separate handling and integration.
