Unsupervised segmentation and clustering workflow for efficient processing of 4D-STEM and 5D-STEM data
Serin Lee, Stephanie M. Ribet, Arthur R. C. McCray +3
Four-dimensional scanning transmission electron microscopy (4D-STEM) enables mapping of diffraction information with nanometer-scale spatial resolution, offering detailed insight i…
PhaseT3M: 3D Imaging at 1.6 Ã Resolution via Electron Cryo-Tomography with Nonlinear Phase Retrieval
Juhyeok Lee, Samuel W. Song, Min Gee Cho +5
Electron cryo-tomography (cryo-ET) enables 3D imaging of complex, radiation-sensitive structures with molecular detail. However, image contrast from the interference of scattered e…
Nanocrystal Geometry Governs Phase Transformation Pathways in Palladium Hydride
Daewon Lee, Sam Oaks-Leaf, Hyeonjong Ma +14
Pathways and structural dynamics of phase transformations impact performance of materials in energy and information storage technologies. Palladium hydride () nanoc…
TEM Agent: enhancing transmission electron microscopy (TEM) with modern AI tools
Morgan K. Wall, Alexander J. Pattison, Edward S. Barnard +2
Recent improvements in large language models (LLMs) have had a dramatic effect on capabilities and productivity across many disciplines involving critical thinking and writing. The…
Deep generative priors for robust and efficient electron ptychography
Arthur R. C. McCray, Stephanie M. Ribet, Georgios Varnavides +1
Electron ptychography enables dose-efficient atomic-resolution imaging, but conventional reconstruction algorithms suffer from noise sensitivity, slow convergence, and extensive ma…
New avenues for characterizing individual mineralized collagen fibrils with transmission electron microscopy
Tatiana Kochetkova, Stephanie M. Ribet, Lilian M. Vogl +5
Bone serves as a remarkable example of nature's architectured material with its unique blend of strength and toughness, all at a lightweight design. Given the hierarchical nature o…
