Conventional metal–organic framework (MOF) powders have periodic micro/mesoporous crystalline architectures tuned by their three-dimensional coordination of metal nodes and organic linkers. To add practical macroscopic shapeability extrinsic hierarchical porosity, fibrous MOF aerogels were produced synthesizing crystals on the template TEMPO-cellulose nanofibrils. Cellulose nanofibrils not only offered porosities mechanical flexibility for resultant aerogels, but also shifted balance...
Abstract Nanometerization of liquid metal in organic systems can facilitate deposition metals onto substrates and then recover its conductivity through sintering. Although having broader potential applications, producing stable aqueous inks keeps challenging because rapid oxidation when exposing to water oxygen. Here, a biocompatible ink is produced by encapsulating alloy nanodroplets gallium indium (EGaIn) into microgels marine polysaccharides. During sonicating bulk EGaIn alginate...
Abstract Electricity harvest from ubiquitous water has been endeavored, using nanogenerators based on carbon nanomaterials, to acquire renewable and clean energy cope with fossil depletion pollution as well. Meanwhile, though many biological organisms can harness for bioelectricity, it is still challenging produce nanomaterials billions of tons annual production in nature. Herein nanofibrils, including cellulose, chitin, silk fibroin, amyloid, are produced either by liquid‐exfoliation...
Liquid metal (LM) droplets show the superiority in coalescing into integral liquid conductors applicable flexible and deformable electronics. However, large surface tension, oxide shells poor compatibility with most other materials may prevent spontaneous coalescence of LM and/or hybridisation composites, unless external interventions (e.g., shear laser) are applied. Here, we that biological nanofibrils (NFs; including cellulose, silk fibroin amyloid) enable evaporation-induced sintering...
Quaternized chitosan (QCh) was homogeneously synthesized by reacting with 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC) in alkali/urea aqueous solution for the first time. The structure and properties of QCh were characterized using element analysis, FT-IR, 13C NMR, SEC-LLS, rheology, viscometer, ξ-potential measurements. Subsequently, polyelectrolyte complex (PEC) hydrogels constructed situ polymerization acrylic acid (AA) monomers concentrated solution. mechanical behavior...
Solar-driven steam generation is anticipated as one of the most promising and inventive technologies to address primitive issues water shortage. Although extensive attempts have been made develop highly efficient solar generators, hindrances are faced integrate all desired functions in a single evaporating system. Herein, we designed semiconductive situ-polymerized MnO2 nanowires/chitosan (SPM-CH) hydrogels flexible, built-in, vertically aligned, macropore-based channels (∼0.5 μm pore size)...
Antibacterial hydrogels have emerged as a promising approach for effective wound treatment. However, despite extensive research on the fabrication of antibacterial hydrogels, it remains challenging to develop injectable, biocompatible, transparent, and mass-producible with properties. In this study, we successfully fabricated an drug-loaded composite hydrogel, named CC45/OKG40/HS, through Schiff base reaction between carboxymethyl chitosan (CC) oxidized konjac glucomannan (OKG), followed by...
Silk, one of the strongest natural biopolymers, was hybridized with Kevlar, synthetic polymers, through a biomimetic nanofibrous strategy. Regenerated silk materials have outstanding properties in transparency, biocompatibility, biodegradability and sustainability, promising applications as diverse pharmaceutics, electronics, photonic devices membranes. To compete super mechanic their counterpart, regenerated been inorganic fillers such graphene carbon nanotubes, but frequently lose...
2D nanomaterials have various size/morphology-dependent properties applicable in electronics, optics, sensing, and actuating. However, intensively studied inorganic are frequently hindered to apply some particular industrial fields, owing harsh synthesis, high-cost, cytotoxicity, nondegradability.

Polysaccharide-based injectable hydrogels have several advantages in the context of biomedical use. However, main obstruction associated with utilization these clinical application is their poor mechanical properties. Herein, we describe situ gelling nanocomposite based on quaternized cellulose (QC) and rigid rod-like cationic nanocrystals (CCNCs), which can overcome this challenge. In all cases, gelation immediately occurred an increase temperature, CCNCs were evenly distributed throughout...

Abstract Traditionally, energy‐intensive and time‐consuming postmechanical disintegration processes are inevitable in extracting biopolymer nanofibrils from natural materials thereby hinder their practical applications. Herein, a new, convenient, scalable, energy‐efficient method for exfoliating (ChNFs) various chitin sources via pseudosolvent‐assisted intercalation process is proposed. These self‐exfoliated ChNFs possess controllable thickness 2.2 to 0.8 nm, average diameter of 4–5 high...
