Dual Vacancy Engineering in Alloyed Ga‐Zn‐Cu‐Se Quantum Dots for Photocatalytic 5‐Hydroxymethylfurfural to 2,5‐Diformylfuran Conversion

Advanced Materials, EarlyView.
A dual‐vacancy‐engineered strategy is developed to construct Ga‐Zn co‐doped CuSe quantum dots (GZC QDs) via cation exchange using CuSe as a template. By precisely introducing Cu and Se vacancies, the optimized sample efficiently facilitates the selective photocatalytic oxidation of 5‐hydroxymethylfurfural (HMF) to 2,5‐diformylfuran (DFF), achieving an ...

Photonic Crystal Enhanced Microscopy on a 2D Photonic Crystal Surface

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This work demonstrates the design, fabrication, and the first‐time test of a 2D photonic crystal surface for photonic resonator absorption microscopy. The designed surface uniformly enhances electromagnetic near fields, achieving > 100% improved detecting uniformity for surface‐captured AuNPs from a blocking biosensor assay aimed for detecting SARS‐CoV‐
