Concurrent tunable structural color, luminescence, and afterglow in single ZnS: X@SiO2 spheres via SiO2‐nanoarmor and calcination decoupling collaborative strategy

Smart Molecules, EarlyView.
For the first time, tunable structural color, luminescence, and afterglow are integrated into single ZnS:X@SiO2 spheres via a SiO2‐nanoarmor and calcination decoupling strategy, achieving 250–410 nm monodisperse wurtzite spheres with 91% phase conversion, 12.8% PLQY, and 12.27 s afterglow. Abstract The integration of structural color, photoluminescence,

Strategic Spatial Segregation in Silicon Photoelectrodes: Decoupling Catalytic and Optical Functions for High‐Efficiency Solar Water Splitting

Small Structures, Volume 6, Issue 5, May 2025.
A novel spatial segregation strategy for silicon photoelectrodes is demonstrated, where catalyst wires surrounded by tapered microwires effectively decouple competing optical and catalytic requirements. This architectural innovation enables optimal light absorption and catalytic activity while maintaining efficient charge transport, achieving 96.5 ...

Arbitrary Wavefront Manipulation in Real Space and Momentum Space Based on Elliptical Structures

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
Leveraging elliptical structures—while preserving real space arbitrary wavefront manipulation—we generalize the manipulation to momentum space rather than only sustaining topological singularities. Multifunctional integrated outputs, such as beam deflection and focusing, can be flexibly achieved in the near–infrared communication band, and the ...

Three‐Stage Fluid‐Assisted Dual‐Mode Janus E‐Skin for Thermally Comfortable Multiplexed SERS Sweat Analysis and Strain Monitoring

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Wearable sweat sensors face persistent trade‐offs between multiplexed detection, signal stability, and wearing comfort. Here, we present a Janus electronic skin (e‐skin) with dual‐mode functionality, offering both thermal and moisture comfort.

Spectrally-Shaping Viscoelastic Finite-Difference Time Domain (FDTD) model of a membrane

, 2019
The damping of musical instruments is spectrally-shaped, showing beatings and non-exponential decay. Such behaviour can be explained by viscoelastic damping, which also shows spectral sidebands and mode coupling. Previous physical models of musical instruments do only roughly implement viscoelastic damping.

Metal/Si Nanowire Arrays for Hot Electron Catalysis

Small, Volume 22, Issue 55, 1 October 2026.
Silicon nanowire arrays enhance plasmon‐driven catalysis by strengthening light–matter interactions on Au and Ag nanostructured coatings. Hotspot accessibility, rather than near‐field intensity alone, governs photocatalytic performance, while Ag nanoshells exhibit superior activity. The work establishes high‐surface‐area Si nanowire arrays as versatile

From Nano‐ to Picocavities: The Role of Atomistic Features

Small Structures, Volume 7, Issue 10, October 2026.
Atomistic features strongly affect the plasmonic response of Ag and Au nano‐ and picocavities. By analyzing induced charge densities, electric field maps, and localization areas, the role of atomistic morphology in controlling field confinement and enhancement is revealed, establishing a direct structure–property relation between atomic‐scale features ...
