Correlative 3D Mapping of Structure, Composition, and Valence State Dynamics in Battery Cathodes via Simultaneous ADF-EDS-EELS Tomography
Jaewhan Oh, Sunggu Kim, Chaehwa Jeong +6
Understanding degradation in battery cathodes and other functional materials requires simultaneous knowledge of structural, chemical, and electronic changes in three dimensions (3D…
Autonomous Electron Tomography Reconstruction with Machine Learning
William Millsaps, Jonathan Schwartz, Zichao Wendy Di +2
Modern electron tomography has progressed to higher resolution at lower doses by leveraging compressed sensing methods that minimize total variation (TV). However, these sparsity-e…
"Extraordinary" Phase Transition Revealed in a van der Waals Antiferromagnet
Xiaoyu Guo, Wenhao Liu, Jonathan Schwartz +12
While the surface-bulk correspondence has been ubiquitously shown in topological phases, the relationship between surface and bulk in Landau-like phases is much less explored. Theo…
Imaging 3D Chemistry at 1 nm Resolution with Fused Multi-Modal Electron Tomography
Jonathan Schwartz, Zichao Wendy Di, Yi Jiang +15
Measuring the three-dimensional (3D) distribution of chemistry in nanoscale matter is a longstanding challenge for metrological science. The inelastic scattering events required fo…
Real-time 3D analysis during electron tomography using tomviz
Jonathan Schwartz, Chris Harris, Jacob Pietryga +13
The demand for high-throughput electron tomography is rapidly increasing in biological and material sciences. However, this 3D imaging technique is computationally bottlenecked by…
A three-stage magnetic phase transition revealed in ultrahigh-quality van der Waals magnet CrSBr
Wenhao Liu, Xiaoyu Guo, Jonathan Schwartz +10
van der Waals (vdW) magnets are receiving ever-growing attention nowadays due to their significance in both fundamental research on low-dimensional magnetism and potential applicat…
Imaging Atomic-Scale Chemistry from Fused Multi-Modal Electron Microscopy
Jonathan Schwartz, Zichao Wendy Di, Yi Jiang +9
Efforts to map atomic-scale chemistry at low doses with minimal noise using electron microscopes are fundamentally limited by inelastic interactions. Here, fused multi-modal electr…
Contamination of TEM Holders Quantified and Mitigated with Open-Hardware, High-Vacuum Bakeout System
Yin Min Goh, Jonathan Schwartz, Emily Rennich +3
Hydrocarbon contamination plagues high-resolution and analytical electron microscopy by depositing carbonaceous layers onto surfaces during electron irradiation, which can render c…
Dynamic Compressed Sensing for Real-Time Tomographic Reconstruction
Jonathan Schwartz, Huihuo Zheng, Marcus Hanwell +2
Electron tomography has achieved higher resolution and quality at reduced doses with recent advances in compressed sensing. Compressed sensing (CS) theory exploits the inherent spa…
Removing Stripes, Scratches, and Curtaining with Non-Recoverable Compressed Sensing
Jonathan Schwartz, Yi Jiang, Yongjie Wang +6
Highly-directional image artifacts such as ion mill curtaining, mechanical scratches, or image striping from beam instability degrade the interpretability of micrographs. These unw…
