Cr3+‐Activated Tunable Near‐Infrared Mechanoluminescence Materials for Potential Water Pollutant Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
Four kinds of magnetite type NIR‐ML materials are synthesized by high‐temperature solid‐state reaction method. The continuous spectral tuning from a sharp R line (698 nm) to a broadband range (650–1000 nm) is realized based on composite engineering, concentration engineering, and lattice engineering strategies.

Ultrabroadband Chiral Emission from Cu Nanocluster Eggshell Membrane/CsPbBr3 QD Composites with a Cholesteric Superstructures

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a novel wide‐bandwidth circularly polarized luminescence (CPL) system combining Cu nanoclusters, perovskite quantum dots, and cholesteric liquid crystals. The design achieves strong CPL emission across 480–750 nm (glum up to 1.31 at 514 nm and 1.46 at 620 nm). Using biomaterials and a simple structure, it offers a promising strategy

Soft Magnetic Artificial Muscles with High Work Density and Actuation Strain via Dual Cross‐Linking Design

open access: yesAdvanced Functional Materials, EarlyView.
A high‐performance magnetic composite actuator that integrates covalent and reversible physical cross‐links within a stiffness‐tunable polymer matrix embedded with functionalized magnetic particles is presented. The actuator exhibits programmable magnetic responsiveness, a stiffness switching ratio of 1.37 × 103, stretchability up to 1274%, large ...

Strain‐Activated Photo‐Dehalogenation Unlocks Low‐Energy One and Two‐Photon 3D Microfabrication

open access: yesAdvanced Functional Materials, EarlyView.
5,14‐NMI‐Cz acts, conversely to its 7,10‐NMI‐Cz(7,10‐'dibromo‐2‐(2,6‐diisopropylphenyl)‐1H‐benzo[lmn]carbazolo[9,1‐bc][2,8]phenanthroline‐1,3(2H)‐dione) counterpart, as modular photoinitiator with panchromatic photoactivity, featuring a weak C–Br bond from geometric strain for efficient Type I & II initiation. These studies demonstrate applicability of
