Programming Defects and Cavities into Colloidal Crystals Engineered With DNA
Advanced Materials, EarlyView.Seed‐mediated crystallization is adapted for colloidal crystals to design cavities and defect architectures through chemically programmed DNA sequences and appropriate seed particle geometry. This synthetic approach combines tenets from both atomic and colloidal crystallization to deliberately control defect formation in superlattices and enables the ...

Advanced Materials, EarlyView.This study demonstrates enhanced induction heating in cobalt‐doped iron oxide nanoparticles via specific pre‐magnetization, induced by the pre‐alignment of magnetic moments. By correlating Co content with magnetic properties, the research highlights how magnetic pre‐programming enables localized, on‐demand debonding in composites.

Advanced Materials, EarlyView.The polariton‐enhanced Purcell (PEP) effect is demonstrated to enhance the stability of the deep blue phosphor‐sensitized fluorescent (PSF) OLEDs by 3.1 X compared to PSF diodes lacking this effect. In addition, PSF‐OLEDs exhibit reduced EQE roll‐off and deep blue color emission.

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 ...
