Context-Aware Deep Learning for Defect Classification in Atomic-Resolution STEM
Jiadong Dan, Cheng Zhang, Leyi Loh +5
Artificial intelligence is rapidly advancing materials characterization, yet most applications in electron microscopy rely solely on image contrast, overlooking the chemical and ex…
Symmetry quantification and segmentation in STEM imaging through Zernike moments
Jiadong Dan, Cheng Zhang, Xiaoxu Zhao +1
We present a method using Zernike moments for quantifying rotational and reflectional symmetries in scanning transmission electron microscopy (STEM) images, aimed at improving stru…
A multiscale generative model to understand disorder in domain boundaries
Jiadong Dan, Moaz Waqar, Ivan Erofeev +4
A continuing challenge in atomic resolution microscopy is to identify significant structural motifs and their assembly rules in synthesized materials with limited observations. Her…
Single-shot, coherent, pop-out 3D metrology
Deepan Balakrishnan, See Wee Chee, Zhaslan Baraissov +3
Three-dimensional (3D) imaging of thin, extended specimens at nanometer resolution is critical for applications in biology, materials science, advanced synthesis, and manufacturing…
Ptychographic wavefront characterisation for single-particle imaging at X-ray lasers
Benedikt J. Daurer, Simone Sala, Max F. Hantke +13
A well-characterised wavefront is important for many X-ray free-electron laser (XFEL) experiments, especially for single-particle imaging (SPI), where individual bio-molecules rand…
High-throughput ensemble characterization of individual core-shell nanoparticles with quantitative 3D density from XFEL single-particle imaging
Do Hyung Cho, Zhou Shen, Yungok Ihm +16
The structures, as building-blocks for designing functional nanomaterials, have fueled the development of versatile nanoprobes to understand local structures of noncrystalline spec…
An encryption-decryption framework for validating single-particle imaging

Jiadong Dan, Xiaoxu Zhao, Shoucong Ning +4
Progress in functional materials discovery has been accelerated by advances in high throughput materials synthesis and by the development of high-throughput computation. However, a…
ReCoDe: A Data Reduction and Compression Description for High Throughput Time-Resolved Electron Microscopy
Abhik Datta, Kian Fong Ng, Deepan Balakrishnan +5
Fast, direct electron detectors have significantly improved the spatio-temporal resolution of electron microscopy movies. Preserving both spatial and temporal resolution in extende…
Experimental 3D Coherent Diffractive Imaging from photon-sparse random projections
K. Giewekemeyer, A. Aquila, N. D. Loh +17
The routine atomic-resolution structure determination of single particles is expected to have profound implications for probing the structure-function relationship in systems rangi…
