Fabrication and Characterization of a Plasmonic Ellipsoidal Nanohole Array With Chiral Response

Advanced Photonics Research, Volume 7, Issue 2, February 2026.
An intrinsically chiral plasmonic platform is realized using ellipsoidal nanohole arrays where mirror symmetry is broken by a precise 18° structural rotation through a scalable displacement Talbot lithography approach. This architecture yields a significant circular dichroism signal of 20%–30% at normal incidence, offering a robust and high‐performance

Look‐up table correction for beam hardening‐induced signal of clinical dark‐field chest radiographs

Medical Physics, Volume 53, Issue 2, February 2026.
Abstract Background The microstructure of material at a μm$\,\umu\mathrm{m}$ length scale leads to ultra‐small‐angle scattering of X‐rays, which typically occurs, e.g., for lung tissue or some plastic foams. When using an interferometer, this effect alters the visibility of the fringe pattern, which can be detected and resolved by the detector.

Outdoor Stability of 518 cm2 Active Area Screen‐Printed Mesoscopic Carbon‐Based Perovskite Solar Modules Over 12 Months

Advanced Materials Technologies, Volume 11, Issue 2, 22 January 2026.
Mesoscopic carbon‐based perovskite solar cells (C‐PSCs) offer a pathway to stable, scalable, low‐cost photovoltaics via commercially mature fabrication methods. While their potential lifespan has been demonstrated under standardized conditions, few studies examine the behavior of large‐area modules exposed to real‐world environments. Here, 12 months of

Fabrication of Gratings for an X-ray Talbot Interferometer

2006 IEEE International Symposium on MicroNanoMechanical and Human Science, 2006
X-ray based imaging measurement has found applications in fields such as medical diagnosis and nondestructive inspection, having become one of essential technologies. However, its low sensitivity to biologically soft tissues limits scope of applications. Several methods have been developed for X-ray phase imaging.

Automated alignment of XFEL nanofocusing mirrors via wavefront optimization

Journal of Synchrotron Radiation, Volume 32, Issue 6, Page 1534-1538, November 2025.
An automated alignment system for nanofocusing Kirkpatrick–Baez mirrors has been developed at SACLA. A wavefront optimization technique routinely provides nanofocused XFEL beams.An automated alignment procedure, based on wavefront measurement with a single‐grating interferometer, has been developed for precise tuning of Kirkpatrick–Baez nanofocusing ...

Simultaneous signal optimization of refraction and attenuation in x‐ray grating interferometry: A case study for breast imaging

Medical Physics, Volume 52, Issue 10, October 2025.
Abstract Background X‐ray grating interferometry has emerged as a promising imaging technique for breast computed tomography (BCT), offering complementary contrast from refraction beyond conventional absorption imaging. Although it provides higher resolution, the required dose levels remain above those typically used for breast cancer diagnostic ...

Demonstrating grating-based phase-contrast imaging of laser-driven shock waves

Matter and Radiation at Extremes
Single-shot X-ray phase-contrast imaging is used to take high-resolution images of laser-driven strong shock waves. Employing a two-grating Talbot interferometer, we successfully acquire standard absorption, differential phase-contrast, and dark-field ...

Nanoparticle Interferometer by Throw and Catch

Atoms
Matter wave interferometry with increasingly larger masses could pave the way to understanding the nature of wavefunction collapse, the quantum to classical transition, or even how an object in a spatial superposition interacts with its gravitational ...

Non-iterative Directional Dark-field Tomography

Scientific Reports, 2017
Dark-field imaging is a scattering-based X-ray imaging method that can be performed with laboratory X-ray tubes. The possibility to obtain information about unresolvable structures has already seen a lot of interest for both medical and material science ...

Optimization Based Evaluation of Grating Interferometric Phase Stepping Series and Analysis of Mechanical Setup Instabilities

Journal of Imaging, 2018
The diffraction contrast modalities accessible by X-ray grating interferometers are not imaged directly but have to be inferred from sine-like signal variations occurring in a series of images acquired at varying relative positions of the interferometer ...
