Abstract Metal‐organic frameworks (MOFs) are highly versatile materials with tunable chemical and structural properties, making them promising for triboelectric nanogenerators (TENGs) electrocatalysis. However, achieving precise control over MOF coordination structures to optimize facet‐dependent properties remains challenging. Here, a facile scalable dual‐solvent synthesis strategy is presented fabricate dendrite Co‐2‐methylimidazole (ZIF‐67‐D), enabling tailored preferred facet environments. Using density functional theory (DFT) calculations synchrotron‐based X‐ray absorption spectroscopy, it demonstrated that ZIF‐67‐D, enriched (112) facets, features reduced Co number enhanced electron‐donating ability compared the conventionally (011) facet‐dominated rhombic dodecahedron ZIF‐67 (ZIF‐67‐R). This engineering boosts TENG charge by 2.4‐fold, OER current 9.9‐fold (@1.65 V), HER 1.9‐fold (@‐0.3 V). The (112)/(011) ratio can be also tuned precisely alter output. Moreover, optimized ZIF‐67‐D shows excellent stability, maintaining electrolyzer performance 72 h devices even in high humidity. Consequently, ZIF‐67‐D‐based (D‐TENG) exhibit robust energy generation power ZIF‐67‐D||ZIF‐67‐D electrolyzers continuous hydrogen (H 2 ) production. These findings introduce new paradigm converting mechanical into sustainable energy, offering insights high‐performance harvesting systems.

In this work, a novel and pioneering route was developed for the large-scale fabrication of PLA-based multilayer films with high barrier properties by forced assembly layer multiplication coextrusion. The process involved coextruding cellulose nanocrystal (CNC)-filled polylactide (PLA) biocomposite, obtained liquid feeding method, highly crystalline poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) into alternating structures number layers up to 513. degree CNC dispersion in PLA/CNC-based composite architecture were first evaluated TEM observations. Subsequently, role PHBV under confinement on crystallization behavior gas permeability thoroughly investigated. It found that basically maintained their structure architectures, particles overall well-dispersed at mean length 318 nm. Nevertheless, instability breakup began occur 129 due formation microscale aggregates. geometric effect resulted gradual restriction both PLA phases/layers as increased. Notably, an increase oriented edge-on lamellar/crystal along normal direction detected. Consequently, remarkable reduction oxygen transmission rate (OTR) realized when increasing confinement. Additionally, multimicro/nanolayers large exhibited higher flexibility, while maintaining considerable tensile strength. conclusion, study provides innovative solution continuous melt-processing biodegradable flexible enhanced properties, making them suitable food packaging applications.

Abstract Zwitterionic hydrogels have attracted intensive attentions for their exceptional hydration and anti‐fouling properties, while the exploration rational structural designs to achieve multi‐function superior anti‐freezing capability remains an ongoing mission. Herein, a new multi‐functional zwitterionic monomer (ACHPES) is designed developed from which novel are fabricated. The pyridinium‐sulfonate motif endows hydrogel with discoloration in both visible light fluorescence response pH stimulus, enabling unique multi‐channel information encryption highly sensitive Cu 2+ detection threshold of 0.64 ppm. design carbamate group fulfils high bonding capacity water, leading capability. As such, exhibit extremely low water freezing point −47.3 °C breaking elongation ≈500% at −20 °C. outstanding enables sensors electrolytes excellent operational performance temperatures. This innovative strategy offers avenue functionalization application icy temperature.
