Constructing Covalent Organic Polymers through Dative B─N Bonds: Synthesis, Single Crystal Structures, and Physical Properties

Advanced Functional Materials, EarlyView.
Dynamic linkages are highly attractive in preparing single crystals of covalent organic polymers (COPs). Here, single crystals of two COPs CityU‐15 and CityU‐16 based on reversible B─N bonds are constructed using tetra(4‐pyridyl)tetrathiafulvalene and tetra(4‐pyridyl)porphine as monomers.

Direct Ink Writing of Conductive Hydrogels

Advanced Functional Materials, EarlyView.
This review examines the use of direct ink writing (DIW) for fabricating conductive hydrogels with customizable 3D structures. It outlines the rheological requirements for successful DIW, followed by an exploration of the materials and ink formulations used to impart electronic and/or ionic conductivity to hydrogels while maintaining printability ...

Holistic Analysis of Material Properties in Phylogenetically Diverse Spider Silks and Their Influence on Cell Adhesion

Advanced Functional Materials, EarlyView.
Translation of recombinant spider silks as fillers for nerve guidance conduits in long‐segment nerve reconstruction demands a detailed examination of native counterparts. Thus, this study conducts a comprehensive analysis of the material properties of four phylogenetically diverse spider silks and their impact on Schwann cell adhesion, pinpointing key ...

Medium‐Entropy Engineering of Magnetism in Layered Antiferromagnet CuxNi2(1‐x)CrxP2S6

Advanced Functional Materials, EarlyView.
This study explores the aliovalent substitution strategy with Cu and Cr replacing Ni in Ni₂P₂S₆ compounds to engineer magnetism. By creating CuxNi2(1‐x)CrxP2S6 medium‐entropy alloys, the research reveals the evolution of distinct magnetic phases, including the creation of weak ferromagnetism in intermediate compositions.

Al₂O₃‐Functionalized Carbon Nanomembranes with Enhanced Water Permeance and Selectivity for Efficient Air Dehumidification

Advanced Functional Materials, EarlyView.
Carbon nanomembranes with ultra‐thin Al2O3 functionalization are less than 15 nm thin and exhibit outstanding permeation performance with a water vapor/nitrogen selectivity higher than 1 × 104, twice that of pristine CNMs, and an exceptionally high water vapor permeation rate for potential applications in air dehumidification.

Hierarchically Engineered Triple‐Defensive Antifouling Coating with Well‐Regulated Structure for Enhanced Wastewater Treatment

Advanced Functional Materials, EarlyView.
Inspired by shark skin, which has a hydrophilic “denticle layer” and a low surface energy “mucus layer,” a triple‐defense antifouling coating is developed. This coating features a robust hydrophilic catalytic nanoparticle layer overlaid with dispersed hydrophobic perfluoro‐silane domains, optimizing fouling resistance, release, and degradation for ...

Superlubricious Surfaces Through Surface Attached Hydrogels Obtained by C,H‐insertion Crosslinking

Advanced Functional Materials, EarlyView.
Taking synovial joints as a source of inspiration, the friction properties of surfaces covered with 1d‐swelling polyelectrolyte hydrogels in combination with a shear‐thinning aqueous lubricant are studied. Such systems obtained by C,H insertion crosslinking show superlubricious behavior, even surpassing the friction values reported for the natural ...
