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 ...

Exposure to 5G Radiofrequency and Physiological Effects in Healthy Young Adults: Insights Into Heart Rate Variability and Salivary Stress Biomarkers

Bioelectromagnetics, Volume 47, Issue 5, July 2026.
ABSTRACT This study investigated the potential impact of fifth‐generation (5 G) radiofrequency (RF) on the autonomic nervous system (ANS). Electrocardiograms (n = 43) and salivary samples (n = 33) were collected from healthy young volunteers before, during, and after exposure to a 3.5 GHz frequency (electrical field intensity ~1–2 V/m) emitted by an ...

Modeling of Elves Doublets Based on Variations of the Lightning Return Stroke Current

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Elves are transient luminous events appearing above thunderclouds. They are produced by high peak current lightning events. They occasionally appear as doublets or in general as multiplets. We model elves doublets by setting the temporal and spatial variations of the return stroke current amplitude and we show that our modeling results are ...

Dynamic Holographic Display With Multiplexed Dielectric Metasurfaces

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Based on multiplexed metasurfaces, we show hybrid multiplexing of polarization, wavelength, and orbital angular momentum can be applied for dynamic tuning. Our strategy presents a highly compact and efficient solution for high‐capacity, multi‐dimensional holography, with promising applications in advanced displays, data storage, optical encryption, and

Finite-Difference Time-Domain (FDTD) Modelling of Space-Time Modulated Metasurfaces

, 2016
A finite-difference time-domain (FDTD) modelling of finite-size zero thickness space-time modulated Huygens' metasurfaces based on Generalized Sheet Transition Conditions (GSTCs), is proposed and numerically demonstrated. A typical all-dielectric Huygens' unit cell is taken as an example and its material permittivity is modulated in both space and time,

Toward Reliable Spectroscopic Analysis of Reaction Kinetics in Polaritonic Chemistry

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
Vibrational strong coupling has been reported to modify chemical reaction rates, yet its mechanism remains unresolved. We expose pitfalls in UV/Vis‐based kinetic analyses and emphasize the need for standardized cavity protocols. ABSTRACT Recent reports suggest that chemical reaction rates can change inside an optical cavity.
