Enhanced Actuation Stability of Liquid Crystal Elastomer Actuators With Diels–Alder Dynamic Bonds

Small, EarlyView.
By leveraging furan substitution, enhanced thermal stability during actuation of liquid crystal elastomers (LCEs) with Diels–Alder dynamic (DA) bonds was achieved. This work demonstrates that 3‐substituted furan broadens the actuation window of LCEs with DA bonds and enables superior thermomechanical stability and cycling performance at elevated ...

Electrically Switchable Diffraction Grating Based on Electrophoretic Redistribution of Carbon Black Nanoparticles

Small, EarlyView.
Electrically reconfigurable diffraction gratings based on electrophoretic carbon black (CB) nanoparticles are demonstrated. Voltage‐driven particle redistribution forms periodic absorbing patterns with switchable wide‐ and narrow‐slit diffraction modes. The proposed diffractor exhibits negligible polarization dependence, wide‐temperature operation from

Cu+‐Driven Formate Selectivity in Oxidation‐State‐Dependent CO2 Reduction on Cu2O|Graphene

Small, EarlyView.
A Cu2O|graphene heterostructure enables interfacial electronic self‐regulation that stabilizes catalytically active Cu+ species under cathodic CO2 reduction conditions. Suppressed over‐reduction preserves structural integrity and promotes *OCHO pathway, resulting in durable and highly selective electrochemical conversion of CO2 to formate.

Concurrent tunable structural color, luminescence, and afterglow in single ZnS: X@SiO2 spheres via SiO2‐nanoarmor and calcination decoupling collaborative strategy

Smart Molecules, EarlyView.
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,

Interlayer‐Catalyst Method for Metal‐Assisted Chemical Etching of Ultra‐High Aspect Ratio Silicon Nanostructures

Small Methods, EarlyView.
An advanced patterning method is presented for metal‐assisted chemical etching. The interlayer replaces the resist and enables catalyst deposition on a clean interface. The prepared samples show improved performance with a more reproducible etching profile, higher aspect ratio, and increased consistency over a larger area.
