Sample_data/em/ — Electron Microscopy

← Back to Sample Data

This folder contains electron microscopy data of two types, all sharing the same imaging modality family.

PNG images from Kaggle’s EM Particle Segmentation dataset:

Three grayscale SEM images of electrochemical battery-cell cross-sections (PNG, 512 × 512 – 697 × 517 px), sourced from a public Kaggle dataset. These images show multi-phase microstructures typical of lithium-ion electrode materials and serve as the common reference input throughout the preprocessing, clustering, inpainting, feature-extraction, physics-based image generation, and zero-shot segmentation notebooks.

Modality: Scanning Electron Microscopy (SEM)
Used by: preprocessing_basics, clustering_basics, example_inpainting, feature_extract_basics, example_physics_based, example_sam1, example_sam2
Data from: Kaggle — Electron Microscopy Particle Segmentation

TEM/EDS files:

Four files from two TEM/EDS experiments:

  • LMP_LATP_19500X_0005.dm3 — High-resolution TEM bright-field image of a Li1.3Al0.3Ti1.7(PO4)3 (LATP) solid electrolyte pellet at 19 500 × magnification. Stored in Gatan Digital Micrograph 3 (DM3) format and loaded via load_data() in the io_dm3 notebook.

  • LMP_LATP_EDS_Location3_0001.emi and LMP_LATP_EDS_Location3_0001_1.ser — Companion EDS spectrum-image pair for the same LATP sample acquired with the FEI/TIA software stack. The .emi file contains the XML project metadata; the .ser file holds the raw spectrum-image data cube. Loaded together via load_data() in the io_emi and io_ser notebooks.

  • Zn-13.emi — EDS spectrum-image of a zinc-containing sample acquired in the same FEI/TIA format.

Modality: Transmission Electron Microscopy (TEM) and Energy-Dispersive X-ray Spectroscopy (EDS)
Used by: io_dm3, io_emi, io_ser
Data provided by: Dr. Junbeom Park
