Circular Phase Representation and Geometry-Aware Optimization for Ptychographic Image Reconstruction
Carson Yu Liu, Jun Cheng, Chien-Chun Chen +1
Traditional iterative reconstruction methods are accurate but computationally expensive, limiting their use in high-throughput and real-time ptychography. Recent deep learning appr…
Observation of Mesoscopic Clathrate Structures in Ethanol-Water Mixtures
Wei-Hao Hsu, Tzu-Chieh Yen, Chien-Chun Chen +3
Water-alcohol mixtures exhibit many abnormal physicochemical properties, the origins of which remain controversial. Here we use transmission electron microscopy (TEM), nanoparticle…
Deciphering chemical order/disorder and material properties at the single-atom level
Yongsoo Yang, Chien-Chun Chen, M. C. Scott +13
Correlating 3D arrangements of atoms and defects with material properties and functionality forms the core of several scientific disciplines. Here, we determined the 3D coordinates…
Nanomaterial datasets to advance tomography in scanning transmission electron microscopy
Barnaby D. A. Levin, Elliot Padgett, Chien-Chun Chen +17
Electron tomography in materials science has flourished with the demand to characterize nanoscale materials in three dimensions (3D). Access to experimental data is vital for devel…
Three-dimensional coordinates of individual atoms in materials revealed by electron tomography
Rui Xu, Chien-Chun Chen, Li Wu +11
Crystallography, the primary method for determining the three-dimensional (3D) atomic positions in crystals, has been fundamental to the development of many fields of science. Howe…
Reply to "Local Filtering Fundamentally Against Wide Spectrum"
Jianwei Miao, M. C. Scott, Chien-Chun Chen +6
After carefully studying the comment by Wang et al. (arXiv:1408.6420), we found it includes several mistakes and unjustified statements and Wang et al. lack very basic knowledge of…
Three-dimensional coherent X-ray diffraction imaging of a whole, frozen-hydrated cell
Jose A. Rodriguez, Rui Xu, Chien-Chun Chen +13
A structural understanding of whole cells in three dimensions at high spatial resolution remains a significant challenge and, in the case of X-rays, has been limited by radiation d…
Multi-Shell Ankylography
Leigh S. Martin, Chien-Chun Chen, Jianwei Miao
Three-dimensional (3D) imaging techniques appeal to a broad range of scientific and industrial applications. Typically, projection slice theorem enables multiple two-dimensional (2…
Single-shot 3D structure determination of nanocrystals with femtosecond X-ray free electron laser pulses
Rui Xu, Huaidong Jiang, Changyong Song +26
Coherent diffraction imaging (CDI) using synchrotron radiation, X-ray free electron lasers (X-FELs), high harmonic generation, soft X-ray lasers, and optical lasers has found broad…
Oversampling smoothness (OSS): an effective algorithm for phase retrieval of noisy diffraction intensities
Jose A Rodriguez, Rui Xu, Chien-Chun Chen +2
Coherent diffraction imaging (CDI) is high-resolution lensless microscopy that has been applied to image a wide range of specimens using synchrotron radiation, X-ray free electron…
Potential and Challenge of Ankylography
Jianwei Miao, Chien-Chun Chen, Yu Mao +2
The concept of ankylography, which under certain circumstances enables 3D structure determination from a single view [1], had ignited a lively debate even before its publication [2…
Electron tomography at 2.4 Å resolution
M. C. Scott, Chien-Chun Chen, Matthew Mecklenburg +6
Transmission electron microscopy (TEM) is a powerful imaging tool that has found broad application in materials science, nanoscience and biology(1-3). With the introduction of aber…
3D Imaging of a Phase Object from a Single Sample Orientation Using an Optical Laser
Chien-Chun Chen, Huaidong Jiang, Lu Rong +4
Ankylography is a new 3D imaging technique, which, under certain circumstances, enables reconstruction of a 3D object from a single sample orientation. Here, we provide a matrix ra…
