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,

Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites
Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.

This publication describes how R. B. Woodward and Roald Hoffmann crafted their masterpiece publications. Illustrations include Woodward's first draft of the famous “Violations There are none. Nor can violations be expected of so fundamental a principle of maximum bonding.” Original but discarded text shows the stepwise paths toward the W‐H masterpieces.

ABSTRACT Rationale Dielectric barrier discharge ionisation (DBDI) in an active‐capillary configuration (including the commercial SICRIT source) is widely used as a soft, ambient‐pressure ionisation method for vapours and gases, yet the role of water vapour in controlling reagent ion chemistry and analytical behaviour has not been mechanistically ...

Thermo‐Responsive Tri‐State Photonic Crystals
Counterfeiting remains a pervasive global challenge, persistently undermining legitimate enterprises. Despite advancements, current anti‐counterfeiting materials and technologies fall short in addressing the escalating sophistication of counterfeit ...

We report a wearable photonic patch integrating room light‐ and sunlight‐activatable luminescent particles (RSLPs) for both photochemical tissue bonding and photobiomodulation. RSLPs harvest ambient light and emit red luminescence to drive chlorin e6–mediated collagen crosslinking.

The trade‐off between intersystem crossing and triplet exciton stabilization in PVA‐based self‐protective CPDs is resolved by tuning the alcoholysis degree of PVA. Using PVA with 88% alcoholysis affords NCD88 with an ultralong RTP lifetime of 1.05 s.

Bright and Durable Copper‐Iodide‐Based Nanowire Scintillators
A surface‐protective‐agent (SPA)‐coordinated low‐temperature crystallization strategy regulates the surface microenvironment of CsCu2I3 nanowires at the atomic level. The SPA simultaneously suppresses iodine‐vacancy‐related defects and nonradiative recombination while eliminating Cu2+ species and surface oxide formation, offering a coherent pathway to ...
