Surface micro/nanostructures and interconnected interfacial micropores are fabricated via micro-extrusion roll forming, achieving a water vapor transmission rate of 203.47 g m −2 h −1 . It balances high breathability, moisture permeability, waterproofing and antifouling performance, solving the stuffiness problem of conventional medical films. • Synergistic action of ZnO@SiO 2 nanoparticles and micro/nanostructures delivers an antibacterial rate of 97.69% against Escherichia coli. By regulating radiative properties, it enables passive cooling with a surface temperature approximately 10 °C lower than commercial fabrics. • With PLA/PBAT as the biodegradable matrix, the film can be completely degraded through enzymatic, composting and alkaline pathways. It eliminates white pollution and secondary contamination risks of traditional medical protective films at the material source. Medical protective films are crucial for public health, yet traditional materials often compromise wearer comfort and pose significant environmental challenges due to their non-degradable nature. Herein, a biodegradable and multifunctional composite film is fabricated via micro-extrusion roll forming, composed of a polylactic acid (PLA)/poly(butylene adipate-co-terephthalate) (PBAT) matrix featuring surface and interface micro/nanostructures. The surface micro/nanostructures and interconnected microporous interface endow the medical protective film with a water vapor transmission rate of 203.47 g m −2 h −1 , ensuring excellent breathability and wearing comfort. The synergistic effect of uniformly dispersed ZnO@SiO 2 nanoparticles and the surface micro/nanostructures achieves an antibacterial rate of 97.69% and effectively inhibits contaminant adhesion. Furthermore, the micro/nano structures and micropores are engineered to manipulate radiative properties, resulting in a passive cooling effect with a surface temperature approximately 10 °C lower than that of commercial fabrics. Crucially, addressing the critical issue of plastic pollution, the film exhibits excellent biodegradability through enzymatic, composting, and alkaline pathways, offering a sustainable solution that mitigates the secondary environmental pollution caused by conventional medical films. This work provides a feasible strategy for the scalable production of next-generation medical protective materials that seamlessly integrate wearable comfort, high performance, and environmental sustainability.

Doping with transition metal ions is an effective way to significantly enhance the performance of MOS-based gas sensors. Conventional doping strategies often lack control over morphological evolution and fail to elucidate the complex interactions between dopants and intrinsic defects. Herein, we demonstrated a rational defect-engineering approach by introducing W 6+ dopants into morphology-prefabricated layered ZnO hexagonal prisms, which triggered a controlled transformation into ultrathin nanosheets (15-20 nm thickness) while systematically changing oxygen vacancy and zinc vacancy concentrations. The concentration changes of intrinsic defect, as well as the formation energy, were confirmed through various characterization methods and DFT calculations. The gas sensitivity test results showed that the response has been significantly enhanced after doping W 6+ , which can reach 64 to 1 ppm of NO 2 , and the detection limit was as low as 200 ppb. At the same time, it has excellent stability and selectivity. Finally, the gas-sensing mechanism thoroughly explored the charge balance process caused by W 6+ doping, the functions of oxygen vacancy and zinc vacancy, and the NO 2 sensitization mechanism.

ZnO nanowire in-situ growth on cotton textiles via interface coordination strategy. • Self-activating electro-mechanical intervention for high antibacterial properties. • Modified textiles maintain above 95% against bacteria and viruses after 50 washings. • The antibacterial and antiviral function can be activated by mild finger pressure. The risk of bacterial infection and transmission via textiles has escalated into a significant public health crisis. Herein, self-activated electro-mechanical intervention based on ZnO nanowires was applied to confer high antibacterial efficiency on the textile. This study proposes an interfacial coordination strategy, in which the pre-coordinated Zn 2+ ions on cellulose induce the in-situ growth of a uniform and stable ZnO seed layer on cotton textiles (CTs), thereby enabling the subsequent in-situ growth of Li‑doped ZnO nanowires (Li-doped ZnO nanowires and ZnO seed layer were constructed as a p-n homojunction). The functionalized CTs (LZnO/CTs) generate dual electric fields (piezoelectric field and the built-in field at the p-n junction) under piezoelectric response to induce continuous electron depletion in bacteria; while the nanowire structure enables physical piercing of bacterial membranes to achieve antibacterial purposes. LZnO/CTs showed superior efficient inhibition of E. coli (99.56%), S. aureus (97.19%), and MS2 (99.99%) within 2 min, respectively, via electro-mechanical. Moreover, the modification process preserves the intrinsic physical properties of the textiles, and the sterilization functionality can be readily activated by mild finger pressure. The highly efficient antibacterial and antiviral functional surface on cotton textiles demonstrates substantial practical application potential in personal wearable devices and medical environments.

With the fast progress of ultrasonic transducer applications, higher and higher requirements have been put forward to the performance of the piezoelectric ceramics applied in this field. For power-type ceramics, not only high Q m is needed to reduce the heat and improve the power capacity, but also high d 33 is needed to provide the stronger driving force. In this work, a conventional ternary solid-solution ceramic system (0.05 Pb(Mn 1/3 Sb 2/3 )O 3 -0.47PbZrO 3 -0.48PbTiO 3 ) modified by ZnO and Li 2 CO 3 ( x wt % ZnO + y wt % Li 2 CO 3 ) (designated as: 0.05PMS-0.95PZT + x wt % ZnO + y wt % Li 2 CO 3 ) ( x , y = 0-0.3) was fabricated and researched. The combination of A-site doping of Li 2 CO 3 and B-site doping of ZnO was discovered to be able to enhance the piezoelectric coefficient ( d 33 ) effectively over 500 pC/N and maintain the mechanical quality factor ( Q m ) above 1000 simultaneously. The ZnO act as acceptor dopant to enhance the content of oxygen vacancies but facilitate the motion of domain walls to improve the piezoelectricity. Meanwhile, the A-site substitution of Li + construct an internal biased field to stabilize the domain structure leading to the relatively high Q m . Additionally, The Li 2 CO 3 also worked as sintering aid to form liquid transition phase to improve the densification process. The phase composition, microstructures of natural surfaces and fractured surfaces, electrical properties of ceramics were characterized systematically. The excellent comprehensive piezoelectric properties ( d 33 = 525 pC/N, Q m = 1064, k p = 0.63, T c = 320 °C, tan δ = 0.3% (at 25 °C), ε r = 1344) were achieved in the 0.2 wt % ZnO and 0.2 wt % Li 2 CO 3 co-doped 0.05PMS-0.95PZT ceramic sintered at 1075 °C. These advantages make 0.05PMS-0.95PZT + 0.2 wt% (ZnO and Li 2 CO 3 ) a promising alternative for the improvement and production of high-performance ultrasonic transducers applied in power-type applications.

Electrospun nanofiber membranes incorporating ZnO and Ag nanoparticles were developed using a coaxial electrospinning technique to address microbial contamination in urban water bodies. Polycaprolactone (PCL) served as the polymer matrix, and five formulations (S0–S4) with increasing nanoparticle concentrations were synthesized. Morphological analyses revealed uniform fiber formation with optimal distribution of ZnO and Ag at moderate loadings. S3 (3 wt% ZnO, 0.3 wt% AgNO₃) exhibited a mean fiber diameter of 487 nm, pore size of 2.0 µm, and porosity of 82.8 %. ATR-FTIR and XRD analyses confirmed the presence and dispersion of the incorporated nanoparticles without altering PCL’s structural integrity. Wettability improved significantly, with water contact angle decreasing from 114.3° (S0) to 93.4° (S4). Mechanical testing showed that S3 retained tensile strength (4.3 MPa) and ductility (180 % elongation). Antibacterial assays demonstrated a peak inhibition zone of 11.2 mm against Staphylococcus aureus and 10.4 mm against Escherichia coli . Filtration trials using simulated urban wastewater revealed that S3 achieved a log reduction value of 4.4 (corresponding to 99.996 % bacterial removal), reduced turbidity by 91.8 %, and lowered conductivity by 12.3 %. Despite reduced flux with increasing nanoparticle content, S3 maintained a satisfactory water flux of 112.6 L/m 2 ·h. These multifunctional membranes offer a promising route for enhancing microbial safety and improving physical water quality without the drawbacks of traditional disinfection. This study provides insights into nanoparticle–polymer interactions and offers design guidelines for practical, high-performance water purification systems in urban environments.

Fabrics tend to absorb moisture and foster bacterial growth during use, due to surface hydrophilic groups such as hydroxyl groups. Economically and environmentally, extending antibacterial efficacy through hydrophobic treatment proves highly viable. This study employed pressurized impregnation to load ZnO NPs onto polyester (PET) and cotton fabrics, subsequently modified by octadecyltrichlorosilane (OTS) spraying. Post-OTS treatment, the fabrics achieved water contact angles (WCA) of 148.74 ± 0.95° and 145.47 ± 1.13°, respectively. The composite coating displays substrate adaptability by resisting stains from ordinary liquids (tea, milk, coffee, vinegar, cola, etc.) and synthetic blood while maintaining natural breathability. Bacterial eradication is accomplished by synergistic methods, which include electrostatic interactions between ZnO NPs and bacteria, as well as light-induced reactive oxygen species (ROS), giving the fabrics dual antibacterial and hydrophobic properties. The material's antibacterial and hydrophobic qualities remain constant even after acid-base immersion, UV irradiation, mechanical friction, repeated washing, and ultrasonic treatment. This fully fluorine-free approach is environmentally beneficial, increasing fabrics' application possibilities in industries such as fabric manufacturing and medicine.

Superhydrophobic coatings have emerged as a primary strategy for protecting magnesium alloys. However, their application is often hindered by reliance on harmful fluorinated materials. In this study, a fluorine-free ZnO/ZIF-8 composite coating was fabricated on magnesium alloy surfaces via electrodeposition. By leveraging synergistic effects between ZnO nanostructure roughness and ZIF-8's intrinsic hydrophobicity, superhydrophobicity was achieved without fluorinated surface modifications. Results demonstrate excellent hydrophobic stability, with superhydrophobicity maintained under low-temperature conditions. The water contact angle remained unchanged in sodium chloride solutions of varying concentrations, indicating exceptional salt-induced corrosion resistance. Furthermore, the coating exhibited hydrophilic-hydrophobic transition properties. Electrochemical tests confirmed superior corrosion resistance, showing a corrosion current density of 3.964 × 10 −9 A∙cm −2 and a four-order-of-magnitude increase in charge transfer resistance versus the AZ91D substrate. Molecular dynamics (MD) simulations and density functional theory (DFT) calculations elucidated the corrosion protection mechanism, providing theoretical support for experimental findings. This study integrates experimental and theoretical approaches, offering new insights and technical references for fluorine-free superhydrophobic coatings in magnesium alloy corrosion protection.

Sogatella furcifera ( S. furcifera ) is a serious pest of rice in China. Excessive use of conventional insecticides has led to environmental pollution and other associated issues. The rapid advancement of nanotechnology offers new perspectives for developing innovative pest management strategies. Therefore, we designed a nanopesticide system in which dinotefuran (DNF) was encapsulated within chitosan (CS) and further integrated with ZnO quantum dots (ZnO QDs). The resulting formulation (DNF@CS-P-ZnO) displayed an average particle size of 33.3 nm and a loading efficiency of 17.74 %. Under acidic conditions (pH 5), about 74.93 % of DNF was released within 96 h, showing a controlled release profile. Bioassays confirmed high insecticidal activity, with mortality reaching 93.67 % after 4 d. Mechanistic analyses indicated that the nanoformulation inhibited cytochrome P450 activity and downregulated resistance-related genes ( CYP417A2 , CYP439A3 , CYP4CE3 ), thereby enhancing susceptibility to insecticides. Additionally, the formulation exhibited effective translocation within both pests and rice plants, improved photostability, enhanced wettability, and minimal impact on non-target organisms. Overall, DNF@CS-P-ZnO represents a promising nanopesticide platform that improves pesticide efficacy while reducing environmental risks, offering potential for sustainable rice pest control.

In order to solve the problems of insufficiently rapid response and recovery and poor moisture resistance when zinc oxide is used as a gas sensitive material, a flexible frame material with hydrophobicity, ZIF-8, was introduced to modify the surface of ZnO, and then doped Ag nanoparticles, which can be electron sensitized with ammonia, to obtain Ag modified ZnO@ZIF-8 nanoparticles. At room temperature (RT, ∼25 °C), the response time of ZnO, ZnO@ZIF-8, and Ag modified ZnO@ZIF-8 nanoparticles to 500 ppm ammonia is 74.3 s, 20.2 s, and 8.0 s, and the recovery time is 36.0 s, 23.1 s, and 16.8 s, respectively. The fitting detection limit of Ag modified ZnO@ZIF-8 nanoparticles for ammonia was 83 ppm. Compared with pure ZnO, the moisture resistance of ZnO@ZIF-8 and Ag modified ZnO@ZIF-8 was significantly improved after coating with ZIF-8.

Incorporating fillers into polyethylene (PE) has emerged as a crucial strategy for modulating its thermo-oxidative aging. However, the mechanistic differences among various fillers remain insufficiently understood at the atomic level. To address this issue, this study combines ab initio molecular dynamics (AIMD), first-principles calculations, and thermo-oxidative experiments to investigate the effects of two commonly used fillers, TiO 2 and ZnO, on the thermo-oxidative aging of PE. The results reveal that both fillers promote the dissociation of C–H bonds of PE. TiO 2 enhances the formation of alkyl radicals, driving the generation of hydroxyl and carbonyl groups on the polymer chains. In contrast, ZnO, with its inherently less stable surface structure, exhibits a stronger effect on C–H bond dissociation, leading to significant crosslinking reactions in PE and the development of vinyl groups. These groups are less reactive toward oxygen (O 2 ), hindering the formation of hydroxyl and carbonyl groups by reducing the density of reaction sites between O 2 and carbon chains. Understanding the intricacies and mechanisms of these processes not only deepens our knowledge of the fundamental aspects of PE's thermo-oxidative aging but also provides a basis for designing fillers to effectively regulate its aging behavior.

BACKGROUND Fungal phytopathogens pose a significant threat to global crop yields. The overuse of pesticides leads to pesticide-resistant pathogens, environmental contamination and risks to human health. Consequently, there is an urgent need for effective and ecofriendly antifungal strategies to address these challenges. RESULTS Herein, ZnO-ZIF-8 is synthesized via an in situ growth method to integrate the antifungal property of zinc oxide (ZnO) and the control release property of zeolitic imidazolate framework (ZIF)-8. Results suggest that the inhibition rates of ZnO, ZIF-8 and ZnO-ZIF-8 against Alternaria alternata are 44.4%, 74.1% and 94.4%, respectively, indicating that ZnO-ZIF-8 exhibits the most potent antifungal activity. ZnO-ZIF-8 also causes distortion and fracture of mycelia, significantly impairing spore germination and inhibiting germ tube elongation. CONCLUSION The potential antifungal mechanisms of ZnO-ZIF-8 involve the disruption of fungal cell morphology and structure through the release of Zn 2+ , ultimately leading to fungal cell death. Biosafety assessments indicate that the application of ZnO-ZIF-8 exhibits negligible effects on tobacco seeds and plants. This study provides valuable insights for the effective management of plant fungal diseases and supports sustainable agricultural development. © 2025 Society of Chemical Industry.

The composite photoanodes based on the ZnO/SnO 2 hierarchical structures with high photoelectricity properties have been successfully synthesized, and used in the CdS and CdSe quantum dots co-sensitized solar cells (QDSSCs). In this experiment, the ZnO/SnO 2 nanoparticles (ZS-NP) and hierarchical nanosheets-based microflowers (ZS-MF) were prepared by the one-step hydrothermal route and the morphologies of the products were controlled by the solvent variation. An improved power conversion efficiency of 4.98% was achieved for the cell based on the ZS-MF composite photoanodes, which showed an increase of 21.8% compared to the ZS-NP photoanodes (4.09%). This result is mainly connected to the unique superiority of the three-dimensional hierarchical microflower nanostructures for light scattering and quantum dots loading, which is responsible for the increase of photocurrent values and eventual PCE.
