Advanced Materials, Volume 37, Issue 52, December 29, 2025.This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Strategies for Suppression and Compensation of Signal Loss in Ptychography
PhotonicsX-ray ptychography is an ultrahigh resolution imaging technique widely used in synchrotron radiation facilities. Its imaging performance relies on the quality of the acquired signals. However, the X-ray detectors used often suffer from signal loss due to

Impact of System‐Model Mismatch in Fourier Ptychographic Microscopy
Advanced Photonics Research, Volume 6, Issue 12, December 2025.This study investigates the robustness of Fourier ptychography microscope (FPM) reconstruction algorithms across various scenarios, each representing challenges encountered in practical FPM experiments, and deduces the extent to which FPM can provide diffraction‐limited resolution under the influence of various sources of error.

Partially Coherent Ptychography by Gradient Decomposition of the Probe
, 2017 Coherent ptychographic imaging experiments often discard over 99.9 % of the flux from a light source to define the coherence of an illumination. Even when coherent flux is sufficient, the stability required during an exposure is another important ...

Ptychographic reconstruction of attosecond pulses
, 2015 We demonstrate a new attosecond pulse reconstruction modality which uses an algorithm that is derived from ptychography. In contrast to other methods, energy and delay sampling are not correlated, and as a result, the number of electron spectra to record

Fresnel coherent diffractive imaging tomography of whole cells in capillaries
New Journal of Physics, 2014 X-ray tomography can be used to study the structure of whole cells in close to their native state. Ptychographic Fresnel coherent diffractive imaging (FCDI) holds particular promise for high-resolution tomographic imaging with quantitative phase ...
