Clean Up Behind You ‐ Novel Patterning Approach for Solid Immersion Lenses

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
A focused ion beam (FIB) milling strategy enables rapid fabrication of solid immersion lenses (SILs) with smooth, debris‐free surfaces eliminating the need for post‐processing. The optimized pattern improves efficiency and surface quality. SILs containing NV centers are also investigated, confirming the technique's suitability for quantum and photonic ...

Advancing Photonic Inverse Design with Interpretable Machine Learning

Advanced Photonics Research, Volume 7, Issue 5, May 2026.
The work applies the interpretable machine learning technique called LIME (local interpretable model‐agnostic explanations) to the inverse design of photonic chips, revealing hidden optimization patterns and guiding better starting designs. Using insights from LIME improves performance of two‐mode multiplexers, showing interpretable methods can ...

Deformation‐Induced Formation of Stray Grains in Additive Manufacturing of Single Crystals

Advanced Science, Volume 13, Issue 25, 4 May 2026.
Stray grain formation severely limits the additive manufacturing of single‐crystal alloys. By integrating in situ synchrotron techniques, ex situ characterization, and multi‐scale multi‐physics modeling, the authors reveal that stray grains originate from dislocations at the solid‐liquid interface, rather than thermal supercooling in conventional ...

A Spin‐Texture Spin‐Valves With Van Der Waals Magnets

Advanced Science, Volume 13, Issue 25, 4 May 2026.
ABSTRACT All‐electrical methods for nucleating, detecting, and manipulating spin textures in 2D van der Waals (vdW) magnets can serve as fundamental building blocks for multi‐state spintronic memory, logic, and neuromorphic computing applications.

Metalens‐Enabled Twisted Chromatic Dispersion

Advanced Physics Research, Volume 5, Issue 5, May 2026.
We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...

Mayfly Taxonomic and Functional Diversity in Anthropogenically Impacted Riverine Habitats: Influence of Habitat Morphology, Water Parameters and Fish Assemblages

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Freshwater habitats are globally threatened by various anthropogenic pressures, resulting in reduced habitat quality and diminished biodiversity. Due to their sensitivity to environmental change, mayflies are commonly used in biomonitoring programs worldwide.

Stochastic colonization, transient and boom–bust dynamics shape invasions by native taxa

Ecology, Volume 107, Issue 5, May 2026.
Abstract Boom–bust dynamics (BBD) is a population dynamic pattern described in invasion ecology, where a population suddenly increases (boom) before quickly declining (bust), eventually stabilizing at much lower levels. This initial outbreak is considered a transient phase preceding a long‐term population equilibrium.

Time‐resolved point dosimetry for spread‐out Bragg‐peak proton FLASH using fibre‐coupled scintillators

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background In FLASH radiotherapy, the dose is delivered using ultra‐high dose rates (UHDR), which are approximately 100 times higher than those used for conventional (CONV) treatments. This has shown promise in sparing normal tissue while maintaining tumour control.
