A user‐friendly platform for deep‐learning‐based image enhancement in scanning X‐ray microscopy
Journal of Synchrotron Radiation, EarlyView.A graphical user interface is developed for deep‐learning‐based image enhancement in scanning X‐ray microscopy. By incorporating the intensity of the probe and scan parameters, the graphical user interface enables accessible and reproducible super‐resolution and deblurring of scanning X‐ray datasets, supporting improved analysis of X‐ray fluorescence ...

A Bayesian approach to spectroscopic depth sectioning for locating dopant atoms
Journal of Microscopy, EarlyView.Abstract Locating dopants in 3D is of great interest as advanced materials and devices increasingly rely on control at atomic dimensions, and microscopy tools are constantly in development for this purpose. One potential tool is electron energy loss spectroscopy (EELS) depth sectioning, where a core‐loss signal is collected as a function of electron ...

The PERCIVAL detector: first user experiments
Journal of Synchrotron Radiation, 2023 The PERCIVAL detector is a CMOS imager designed for the soft X-ray regime at photon sources. Although still in its final development phase, it has recently seen its first user experiments: ptychography at a free-electron laser, holographic imaging at a ...

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film
Advanced Functional Materials, Volume 36, Issue 81, 8 October 2026.ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

X‐Ray Multibeam Ptychography at up to 20 keV: Nano‐Lithography Enhances X‐Ray Nano‐Imaging
Advanced ScienceHard X‐rays are needed for non‐destructive nano‐imaging of solid matter. Synchrotron radiation facilities (SRF) provide the highest‐quality images with single‐digit nm resolution using advanced techniques such as X‐ray ptychography.

Advanced Functional Materials, Volume 36, Issue 79, 1 October 2026.A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...
