Kaleidoscopic Electromagnetic Wave Manipulation via a Universal Reconfigurable Metasurface Platform

Electron, EarlyView.
A multidimensional reconfigurable metasurface enables independent control of the amplitude, phase, polarization, and spectral responses of reflected electromagnetic (EM) waves. Integrating spatial, polarization, and spectral manipulation within a single platform, it provides a versatile solution for intelligent EM systems, next‐generation wireless ...

Generating Helical Polymorphic Beams Using Dielectric Metasurfaces

Laser &Photonics Reviews, EarlyView.
Helix‐shaped polymorphic beams are optical fields whose intensity maxima spiral around the propagation axis, enabling particle manipulation through attractive or repulsive forces. Traditionally requiring expensive spatial light modulators, metasurfaces now provide a compact, cost‐effective alternative. This work demonstrates general helical polymorphic

Misalignment‐Robust Dynamic Cascaded Holography Accelerated by Deep Neural Networks

Laser &Photonics Reviews, EarlyView.
Cascaded holography has mainly been studied using metasurfaces. Here, we demonstrate a fully dynamic cascaded holographic system based on two phase‐only spatial light modulators. A misalignment‐tolerant optimization method preserves image quality despite alignment errors, making cascaded holographic systems simpler, more reliable, and easier to use in ...

Vortex Domain Wall Imaging in a 3D Magnetic Nanotube Grown by Focused Electron Beam Induced Deposition

Small, EarlyView.
Synthesis of nanoscale high‐purity Co magnetic nanotubes using a single growth technique, focused electron beam induced deposition (FEBID). Utilizing electron holography and micromagnetic simulations, we demonstrate the nucleation and pinning of tilted vortex domain walls, providing crucial experimental evidence to advance 3D spintronics and ...

Detection and Inhalation Hazard Assessment of Wear Particles Arising From Abrasion of Market‐relevant Graphene Reinforced Composites

Small, EarlyView.
Abrasion of few‐layer graphene (FLG)–epoxy composites generated respirable particles in which FLG remained fully embedded, as confirmed by correlative HR‑TEM, Raman, and ToF‑SIMS analyses. Advanced lung cell models revealed no cytotoxic or inflammatory responses, and only high‑dose epoxy particles reduced mucociliary clearance.

Improving ARTs: Microfluidics as a Tool for Sperm Selection

Andrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Hyperspectral tomographic diffractive microscopy: Development and applications

Journal of Microscopy, EarlyView.
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...
