The development of high-performance wearable electronic demands flexible strain sensors with high sensitivity and robust durability. Herein, we present a high-sensitivity flexible strain sensor based on a polydimethylsiloxane/carbon nanotube (PDMS/CNT) nanocomposite incorporated with electrospun cellulose acetate nanofibers (CANF). The unique integration of CANFs endows the PDMS/CANF/CNT nanocomposite with enhanced mechanical strength and tear resistance while maintaining excellent stretchability. The results show that the tensile strength and toughness of the PDMS/CANF/CNT composites increased from 2.80 to 4.20 MPa and from 1900.00 to 3900.00 kJ/m 3 , respectively. For composites with pre-cut cracks, the tensile strength increased from 0.37 to 1.00 MPa, and the toughness increased from 46.55 to 113.90 kJ/m 3 . SEM observations reveal that CANFs play a critical role in promoting CNT dispersion and preventing agglomeration in the PDMS composites. The resulting flexible strain sensor demonstrates a high gauge factor and good stability over more than 100 stretching-releasing cycles. Furthermore, it was successfully applied in real-time monitoring of various human joint movements, including those of the elbow, knee, and neck. This work highlights the effectiveness of electrospun nanofiber regulation in fabricating advanced PDMS/CNT nanocomposites for next-generation flexible electronic devices. Graphical abstract

In lilies, bulbils are a specialized form of axillary bud essential for vegetative reproduction. To elucidate the molecular mechanisms regulating their formation, we performed transcriptome sequencing on leaf axil tissues from four lily varieties with contrasting bulbil-forming and non-bulbil-forming phenotypes. Analysis revealed differentially expressed genes (DEGs) notably enriched in carbohydrate metabolism pathways. During bulbil development, a gradual increase in leaf axil cellulose content was observed as measured by the anthrone colorimetric method. This correlated with the upregulation of the key cellulose synthase-like gene LlCSLE1 as determined by real-time quantitative PCR. Functional validation confirmed that virus-induced gene silencing (VIGS) of LlCSLE1 led to a significant reduction in both cellulose content and bulbil number. Our findings establish LlCSLE1 as an important regulator of bulbil formation, underscoring the critical role of cellulose-mediated cell wall remodeling in this process. This study provides a molecular foundation for understanding vegetative reproduction and advances molecular breeding strategies in lilies.

PCHZF hydrogel shows 88.2% self-healing and 2.2 MPa fracture stress. • The sensor has rapid 207.3 ms response and captures subtle body movements. • Cellulose nanocrystals are modified to increase surface functional groups and enhance their freeze resistance. • The PCHZF hydrogel-based flexible sensors can still function effectively at -30℃. In recent years, hydrogels have emerged as viable candidates for soft conductors in wearable flexible electronics, due to their distinctive properties including high water content, excellent biocompatibility, and adjustable mechanical properties. However, the crystallization of H 2 O molecules within hydrogels at low temperatures leads to significant deterioration in their toughness and mechanical strength, severely restricting their practical applications in cold environments. Cellulose nanocrystals (CNCs), rod-like nanomaterials with high crystallinity extracted from natural cellulose, have attracted increasing attention due to their outstanding mechanical properties, biocompatibility, and environmental friendliness. In this study, hyaluronic acid (HA) was adsorbed onto the surface of CNCs via hydrogen bonding, forming CNCs@HA nanomaterials. And then zwitterion proline (ZP) and CNCs@HA were incorporated into an acrylic acid-based hydrogel system, resulting in the formation of a novel freeze-resistant and self-healing nanocomposite hydrogel PAA-CNCs@HA-ZP-Fe 3+ (PCHZF). The excellent properties of PCHZF can be attributed to the strong hydrogen bonding network formed among water molecules, CNCs@HA, and ZP molecules. These intermolecular interactions effectively inhibit the crystallization of water and maintain the integrity of the hydrogel matrix at low temperatures. Its compressive strength reaches 2.2 MPa, with a remarkable self-healing efficiency of 88.2%, and it can even achieve reliable sensing performance at extremely low temperatures.

Postharvest fruit losses remain a persistent challenge for sustainable food systems, while many coating technologies still rely on synthetic additives or solvent-intensive processes. Here, we report a fully sustainable route to interfacial cellulose stabilizers for edible Pickering emulsion (PE) coatings. Cellulose was modified via aqueous ball-milling-assisted esterification using valine, isoleucine, and phenylalanine as modifiers, yielding three nanocellulose families with tunable substitution degree and enhanced hydrophobicity. Among these samples, valine-modified cellulose exhibited the highest degree of substitution and the strongest hydrophobicity, which is attributed to its superior water solubility and esterification efficiency. The optimized formulation reached a water contact angle of 82.4° and formed stable soybean-oil emulsions with a mean droplet size of 14.47 μm. To integrate bioactivity, quercetin was directly dissolved in the oil phase to produce antioxidant-functionalized PEs with high encapsulation efficiency (up to 88.56%). Under synergistic antioxidant and moisture-retention effects, the coating reduced mass loss by 49.7% in fresh-cut apples and 60.5% in strawberries, accompanied by significantly delayed browning and maintained sensory acceptability and edibility. Overall, this study establishes an all-biomass preservation platform that links aqueous cellulose esterification to interfacial engineering, antioxidant delivery, and practical postharvest protection, offering a scalable strategy for next-generation food-contact coatings.

Plant fiber paper has poor water resistance due to high cellulose and hemicellulose content. In this study, it was modified with biodegradable natural rosin. Maleic rosin polyvinyl alcohol ester was synthesized and analyzed using Minitab. Carboxylated cellulose nanocrystals (CNCs), known for high strength, stiffness, and biodegradability, were employed as an emulsifier to prepare a stable maleic rosin ester emulsion. The optimal synthesis conditions for maleic rosin ester are a 1:3 molar ratio of maleic rosin to polyvinyl alcohol, along with 1% catalyst and 0.4% initiator, at 220 °C. The resulting emulsion has an average particle size of 406 nm and remains stable at room temperature for 90 days. The double-layer coated paper made with this emulsion exhibits super-hydrophobic properties, with a water contact angle of 160 degrees. It maintains these properties after 50 friction cycles and 300 folds. These findings indicate that superhydrophobic paper holds great potential as a sustainable alternative to plastic materials.

Addressing the practical predicament of uneven global distribution of phosphate resources, this study focuses on transition-metal-based short-chain perfluorocarboxylates (Mn-TFA and Ni-TFA) and systematically investigates their flame-retardant properties, aiming to develop efficient novel phosphorus-free flame retardants. The results of micromorphological characterization indicate that Mn-TFA forms a porous network structure, and Ni-TFA exhibits a polyhedral morphology, both of which possess distinct crystallinity attributed to the coordination interaction between metal ions and carboxylate groups. Flame-retardant performance evaluation demonstrates that samples display excellent flame-retardant effects: their flame-retardant performance is significantly superior to that of ammonium dihydrogen phosphate (the core active component of commercial flame retardants) at all tested concentrations. Particularly under medium-concentration loading conditions, the flame-retardant paper can achieve a self-extinguishing effect. The results of TG-IR-MS combined analysis show that the generation rates of CO and CO2 in the fuel system are significantly accelerated under the action of the flame retardants, indicating that the flame-retardant process is dominated by the condensed-phase effect.

Infected wounds remain difficult to manage because bacterial colonization, biofilm formation, and persistent inflammation severely hinder tissue regeneration, while conventional antibiotic therapy is increasingly challenged by antimicrobial resistance. Herein, we report a visible-light-responsive antibacterial fibrous dressing by integrating a charge-engineered aggregation-induced emission (AIE) photosensitizer into electrospun cellulose acetate (CA) membranes. In this work, the non-cationic AIE photosensitizer is denoted as PS, while its cationic analogue is denoted as PS-1. The molecular cationization strategy endows the photosensitizer PS-1 with enhanced excited-state charge-transfer characteristics, a reduced energy gap, and promoted intersystem crossing, thereby enabling synergistic Type I/Type II reactive oxygen species generation under visible-light irradiation. Benefiting from the favorable spinnability of CA, PS-1 is homogeneously embedded into the fibrous matrix to form free-standing membranes with uniform morphology, good mechanical compliance, and suitable moisture-vapor permeability for wound coverage. Compared with the non-charged analogue, PS-1 exhibits markedly enhanced photodynamic antibacterial activity against both Staphylococcus aureus and Escherichia coli while maintaining low dark cytotoxicity and good cytocompatibility. More importantly, the CA@PS-1 dressing significantly accelerates the healing of S. aureus -infected full-thickness wounds in vivo, as evidenced by rapid wound closure, improved re-epithelialization, enhanced collagen deposition, promoted angiogenesis, and reduced inflammatory responses, without detectable systemic toxicity. This work provides an effective engineering strategy for coupling charge-regulated AIE photosensitizers with carbohydrate polymer electrospun dressings, and offers a promising platform for visible-light-activated anti-infective biomaterials.

The widespread presence of cadmium (Cd) in aquatic environments continues to pose substantial risks to ecosystem safety and public health, highlighting the urgent need for high-performance and recyclable adsorbents. In this study, a novel magnetically separable ternary composite (MCC@CaCO 3 /Fe 3 O 4 ) was successfully fabricated through a combined cooling activation and ion exchange approach, using microcrystalline cellulose as a sustainable and low-cost substrate. Comprehensive characterization techniques including XRD, FTIR, and SEM confirmed the homogeneous dispersion of Fe 3 O 4 and CaCO 3 particles on the cellulose matrix, which exhibited a developed porous structure and abundant oxygen-containing functional groups. The composite demonstrated an exceptional Cd(Ⅱ) adsorption capacity of 617.00 mg g −1 and remarkable reusability, maintaining over 85% removal efficiency throughout twenty consecutive adsorption–desorption cycles. The adsorption process was accurately described by the Langmuir isotherm and pseudo-second-order kinetic models, with the underlying mechanism identified as a synergistic combination of ion exchange, surface complexation, and coprecipitation. This work provides a green and sustainable strategy for the effective treatment of cadmium-laden wastewater using functionalized cellulose-based materials.

Conventional glass fiber (GF) separators play a key role in aqueous zinc ion batteries (AZIBs). However, it is not only expensive but also lacks the ability to inhibit the growth of zinc dendrites, which ultimately leads to a decrease in battery capacity and even short circuits. Therefore, a low-cost functional separator (CF/CMC-NS) was developed by sodium sulfamate (NH2NaSO3) and carboxymethyl cellulose (CMC) based on cotton cellulose fiber (CF) separator. Theoretical calculations and experimental results show that the CF/CMC-NS separator has the ability to modulate ion transport, desolvate Zn2+, and provide a more homogeneous electric field to guide the uniform deposition of Zn2+. As a result, the Zn//Zn battery can be cycled for more than 500 h at a current density of 1 mA cm–2, and the Zn//V2O3 full battery exhibits a high-capacity retention of 96.9% and a high specific capacity of 361.5 mAh g–1 after 4000 cycles at 3.0 A g–1. The functionalized separator provides feasibility and technical support for its practical application in AZIBs by regulating ion transport and inhibiting the growth of zinc dendrites.

The replacement of formaldehyde-based wood adhesives with sustainable alternatives remains a significant challenge due to performance and reusability limitations. Herein, we reported a water-soluble cellulose ethyl phosphite (CEP) adhesive synthesized through a one-pot transesterification strategy in a novel CO 2 -based solvent system, where the superbase served dually as solvent and catalyst. The CEP adhesive demonstrated an integrated performance profile: exceptional bonding strength (5.73 MPa), remarkable extreme-temperature tolerance (maintaining 5.54 MPa at –196 °C and 4.99 MPa at 100 °C), robust humidity resistance (4.87 MPa at the relatively humidity of 90%), good long-term stability (4.20 MPa after 28 d), and reusability. The adhesion mechanism combined strong interfacial hydrogen bonding with mechanical interlocking, while its water solubility enabled reversible bonding and substrate recovery. This unique combination of properties positioned CEP as an ideal adhesive for demanding applications, including reconfigurable furniture, recyclable packaging, and structural components in thermally volatile environments, providing a sustainable material platform for the transition toward a circular bioeconomy.

Responsive wound dressings that operate on the responsive mechanism of “external light stimulation-material photothermal conversion-local microenvironment regulation” are key for protecting wound surfaces, promoting healing, and providing antibacterial effects. This work presents an intercalated structure of cellulose nanocrystals (CNCs)/MoS 2 nanosheets through an innovative “exfoliation-functionalization” strategy. Additionally, CNC-MoS 2 nanosheets serve as highly effective photothermal fillers in polylactic acid (PLA) membranes for wound dressing. These membranes demonstrate excellent UV-blocking capabilities, superior moisture absorption, and good breathability. Remarkably, the membrane with 7 wt% CNC-MoS 2 achieves a 400% increase in moisture absorption, with a water vapor transmission rate (WVTR) of 1025 g/m 2 /day. The membranes also demonstrate excellent photothermal conversion capacity: under irradiation at 2 W/cm 2 , the surface temperature of the membrane with a 7 wt% CNC-MoS 2 content increases by 25.8 °C. It remains stable in phosphate-buffered saline (PBS), demonstrating its potential for use in photothermal therapy within moist wound environments. Upon exposure to near-infrared (NIR) laser irradiation, the hybrid membrane exhibits enhanced antibacterial activity, resulting in 3 mm inhibition zones for both E. coli and S. aureus . The cell biocompatibility reaches 99.5% and migration rate reaches 51.2% after 24 h with NIR. This study provides a strategy for developing responsive wound dressings, offering an innovative solution for complex wound care.

The high energy density and inherent safety feature of solid-state lithium metal batteries (SSLMBs) have drawn considerable interest. Nevertheless, the widespread deployment of SSLMBs remains constrained by insufficient ionic conductivity. Herein, we report a high-performance Li-salt-loaded cellulose nanocrystal-reinforced PVDF-HFP solid-state electrolyte (Li-CPSE) through a sustainable freeze-casting, salt-loading, and in situ photopolymerization strategy. This design enables vertically aligned ion-transport pathways, integrates internal Li + reservoirs with stabilized interfacial chemistry, and constructs a mechanically robust rigid-flexible 3D framework. Owing to these synergistic advantages, Li-CPSE exhibits fast Li + transport (1.06 mS cm −1 at 30 °C), a reduced activation barrier (0.18 e V ), and a broad electrochemical window reaching 5.0 V. Meanwhile, SSLMBs based on Li-CPSE exhibit long-term cycling durability, retaining 98.2% of the original capacity over 500 cycles in Li/LiFePO 4 cells. Flexible pouch cell further demonstrated excellent mechanical resilience and cycling stability, retaining 92.2% capacity over 70 cycles with an average coulombic efficiency of 99.9%, while continuously powering LEDs under bending and cutting. Additionally, bipolar stacking of two pouch cells delivers 6.78 V , sufficient to power commercial 5.3 V devices. The work highlights a scalable and sustainable strategy for advancing high-performance polymer electrolytes toward practical SSLMB applications.
