Covalent Adaptable Networks with Associative Siloxane Exchange Enabled by Amide‐Based Internal Catalysis: Designing for Reprocessability and Extrudability by Increasing the Cross‐Link Density

Advanced Functional Materials, EarlyView.
Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...

Quantum Dots and Perovskites‐Based Physically Unclonable Functions for Binary and Ternary Keys via Optical‐to‐Electrical Conversion

Advanced Functional Materials, EarlyView.
This study investigates optoelectronic PUFs that improve on traditional optical and electrical PUFs. The absorber materials are randomly coated through spray coating, ligand exchange, and dynamic spin coating. Incident light generates wavelength‐dependent binary multikey and enhances security ternary keys, approaching near‐ideal inter‐ and intra ...

Ternary Synergy in Layered Double Hydroxides for Efficient and Stable Nitrate Reduction

Advanced Functional Materials, EarlyView.
Ternary CuZnFe LDH enables efficient electrocatalytic nitrate‐to‐ammonia conversion via controlled in situ reconstruction: zinc leaching creates porous active sites, copper reduced to metallic copper, while iron oxide keeps stable. Synergistic Cu‐Fe redox coupling drives tandem catalysis (nitrate→nitrite→NH3), achieving 95% Faraday efficiency and ...

Molecular‐Level Dual‐Ionophilic Passivation for High‐Areal‐Capacity Lithium Metal Anodes on Nanostructured Paper Electrodes

Advanced Functional Materials, EarlyView.
The effect of a molecular‐level dual‐ionophilic chitosan passivation layer is investigated on a nanostructured paper electrode featuring an interconnected network structure of highly oxygen‐functionalized single‐walled carbon nanotubes (C‐NPE). This molecular coating enabled a high Coulombic efficiency (>99.0%) and stable cycling over 350 cycles at an ...
