Gradient‐Structured Polymer Fiber Mats for Broadly Tunable Multicolor and White Lasing

Laser &Photonics Reviews, EarlyView.
Hierarchically engineered electrospun fiber mats containing separated red, green, and blue dyes enable highly tunable multicolor and white random lasing. Spatially controlled dye distribution suppresses energy transfer, allowing precise color adjustment across wide color gamuts and accurate reproduction of daylight white standards.

Bio‐Derived Nanophotonic Hybrids Enabling Reconfigurable Upconversion for Multilevel Optical Encryption

Laser &Photonics Reviews, EarlyView.
A dual‐gated nanophotonic platform integrates lanthanide‐doped upconversion nanoparticles with a stimuli‐responsive silk–zirconia photonic crystal to enable multilevel optical encryption. Resonant photonic coupling allows hydration‐dependent modulation of visible emission under near‐infrared excitation, achieving reversible switching between decoy and ...

Metal/Si Nanowire Arrays for Hot Electron Catalysis

Small, EarlyView.
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

A Dual‐Frequency Sensitivity Model for Optical Fibre Ultrasonic Sensors in Power Transformer Partial Discharge Detection

High Voltage, EarlyView.
ABSTRACT The detection of partial discharges (PD) on the power transformer tank demands higher sensitivity in ultrasonic detection. To target the detection frequency band for sensor optimisation and enhance sensitivity, this paper presents a dual‐frequency sensitivity model for optical fibre ultrasonic sensors.

Renal‐vascular axis: unmasking its role in vascular endothelial growth factor‐inhibitor vascular toxicity in cancer patients

British Journal of Pharmacology, EarlyView.
Abstract Vascular toxicity is a growing concern in cancer patients receiving vascular endothelial growth factor inhibitor (VEGFi) therapy, posing a significant threat to patient prognosis. While the primary mechanism of VEGFi‐induced vascular toxicity is linked to redox‐sensitive reactions that disrupt vascular tone, leading to hypertension and ...
