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

Acoustic Tweezers‐Assisted Biomaterial Molding in Petri Dishes (TAMP) for Engineering Glioma Tissues With Controlled Cellular and Extracellular Matrix Architectures

Small, EarlyView.
This study introduces an acoustics‐assisted tissue engineering approach, termed “Acoustic Tweezers‐Assisted Biomaterial Molding in Petri Dishes (TAMP),” which enables the fabrication of tissues with customizable extracellular matrix (ECM) geometries and various acoustically constructed internal cellular architectures, including parallel elongated ...

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 ...

In operando imaging of the space‐charge region in a 4H‐SiC MOSCAP using STEM‐EBIC

Journal of Microscopy, EarlyView.
Abstract In situ biasing electron microscopy is the necessary step forward in being able to characterise nanoscale devices and device interfaces. STEM‐EBIC is a new approach that can help fill the missing gaps in creating reproducible methodologies for in situ biasing TEM.

Gaussian Wave Splatting for Computer-Generated Holography

ACM Transactions on Graphics
State-of-the-art neural rendering methods optimize Gaussian scene representations from a few photographs for novel-view synthesis. Building on these representations, we develop an efficient algorithm, dubbed Gaussian Wave Splatting, to turn these Gaussians into holograms.

Planar Super‐Oscillation Diffractive Lenses: Practical Developments and Applications

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
This review examines planar super‐oscillation diffractive lenses as a unified framework for super‐oscillatory lenses and supercritical lenses. It focuses on applications in super‐resolution imaging, micro/nanofabrication, and precision measurement and relates their application‐specific requirements to focal‐field control, multiobjective design ...

Ambident Reactivity in the Phenyl + NO Radical Recombination

Chemistry – A European Journal, Volume 32, Issue 30, 13 August 2026.
ABSTRACT The recombination reaction of nitric oxide (NO) with radicals via its oxygen atom, rather than the more common nitrogen site, offers an intriguing pathway to the formation of oxynitrenes. The photochemical isomerization of nitroso compounds into their corresponding oxynitrenes may involve such a step.
