Flexible wearable pressure sensors exhibit great potential in human activity tracking. Designing visual sensors that integrate active luminescence and motion monitoring is a current research focus. This study proposed a novel five-layer mechanoluminescent piezoelectric sensor (MPS) that synergistically combined the piezoelectricity of Nd-ZnO NRs loaded carbonized silk fabric (CSF) with the luminescent capability of ZnS:Cu/PDMS. A low-temperature hydrothermal method was utilized to incorporate Nd 3 + into the ZnO lattice, while loading the ZnO NRs onto CSF. Nd 3+ was used as a p-type dopant to regulate the piezoelectricity of ZnO, yielding a highly sensitive piezoelectric layer. The resulting MPS exhibited high pressure sensitivity ( S = 27.48 mV/kPa, 0–100 kPa), excellent pressure response (Response time = 150 ms), and outstanding stability (>2400 cycles). Experiments demonstrated that MPS can effectively monitor human joint movement. Due to the introduction of ZnS:Cu, MPS emitted pulsed light which intensity was linearly correlated with the applied stress (R 2 = 0.98). During the nighttime running test, MPS emitted electrical and optical signals corresponding to the bending angles and frequencies of human joints. MPS features visual and electrical dual-mode sensing capabilities, enabling simultaneous monitoring of pressure and strain stimuli to achieve stress visualization. This study provides a feasible approach to developing intelligent sensing systems with active luminescence.

In this study, a high-performance self-powered ultraviolet photodetector (UV PD) is demonstrated, which is fabricated through straightforward hydrothermal and electrochemical deposition techniques. The device features a p–n heterojunction structure composed of ZnO nanorods (NRs) as the n -type bottom layer, poly(3,4-ethylenedioxyselenophene) (PEDOS) as the p -type top layer, and copper oxide (CuO) nanoparticles (NPs) incorporated as a key intermediate layer. Under weak UV irradiation (365 nm, 0.32 mW/cm 2 ), the fabricated UV PD delivers outstanding self-powered performance, attaining a responsivity of 0.185 μA/W and a detectivity of 3.58 × 10⁹ Jones. The CuO NPs insertion layer is verified as the key contributor to device performance enhancement: the UV PD with the CuO NPs interlayer exhibits a responsivity higher than that of the device without the interlayer. This performance boost is attributed to the CuO NPs’ ability to optimize heterojunction quality-specifically; it facilitates carrier generation, transport, and separation while extending carrier lifetime, thus substantially enhancing the responsivity of the CuO NPs/ZnO/PEDOS self-powered UV PD. Additionally, the fabricated self-powered UV PD exhibits excellent multi-cycle stability and robust detection performance under different light intensities. With its high efficiency and low-cost fabrication process, this self-powered UV PD exhibits great potential for practical applications in UV sensing systems.

The escalating demand for multifunctionality in carbon fiber reinforced poly(ether ether ketone) (CF/PEEK) composites has intensified the need for next-generation structural materials. However, achieving a synergistic integration of functional performance and structural integrity—rather than a trade-off—remains a critical challenge. Herein, tetrapod-shaped ZnO whiskers decorated with 2D Ti 3 C 2 T x MXene nanosheets (T-ZnO@MXene) were fabricated via electrostatic self-assembly and incorporated into CF/PEEK composites. This 3D conductive/enhanced network enabled the simultaneous enhancement of mechanical properties, electromagnetic interference (EMI) shielding, and electrothermal deicing capabilities. The optimized CF/T-ZnO@MXene/PEEK composites exhibited a flexural strength of 1970.0 MPa, a flexural modulus of 142.3 GPa, and an interlaminar shear strength of 123.2 MPa, representing improvements of 33.4 %, 45.1 %, and 56.7 % over pristine CF/PEEK, respectively. Concurrently, the through-thickness electrical conductivity surged for 7.7 S/m, corresponding to a 76-fold enhancement, while the EMI shielding effectiveness attained 56.7 dB (a 40.7 % increase). In addition, the composites demonstrated efficient electrothermal conversion and reliable deicing performance. Overall, this work provides an effective route to harmonize structural robustness with multifunctional capabilities in CF/PEEK composites, opening new opportunities for advanced aerospace applications.

The increasing electromagnetic radiation from electronic devices has created an urgent demand for structural composites that simultaneously exhibit high mechanical performance and effective electromagnetic interference (EMI) shielding capability. Herein, a multiscale interfacial modification strategy for carbon fiber (CF) composites is proposed to achieve synergistic enhancement of load transfer efficiency and EMI shielding performance. Zn-based metal–organic framework (Zn-MOF) is first in situ grown on the CF surface via a polydopamine (PDA) interlayer, followed by a two-step calcination process to generate a tightly bonded ZnO/C hybrid coating. Subsequently, a conductive PEDOT:PSS (PP) layer is deposited to construct a hierarchical conductive network. Owing to the optimized multiscale interfacial architecture, the resulting CF-PDA-ZnO-PP composites exhibit significant improvements in mechanical properties, with the interlaminar shear strength, flexural strength, and flexural modulus increased by 44%, 41%, and 87%, respectively, compared with untreated CF composites. Meanwhile, the composite achieves a total shielding effectiveness (SE T ) of 44 dB, indicating excellent EMI shielding capability. This work provides a feasible and scalable approach for the design of next-generation structural composites with high load-bearing capacity and EMI shielding functionality, showing strong potential for applications in aerospace, transportation, and high-end electronic equipment. Highlights PDA assisted uniform growth of Zn-MOF-derived ZnO@C on CF. Simultaneously enhancing interfacial strength and EMI properties. Optimal flexural modulus increased by 87% than pristine CFRP. Optimal EMI SE increased by 101% than pristine CFRP.

Walnut kernels are highly susceptible to oxidative rancidity due to their elevated polyunsaturated fatty acid content; however, existing functional packaging predominantly provide single-mode protection, lacking hierarchical barrier systems specifically constructed for the oxidative characteristics of high-fat nuts. To bridge this gap, an eco-friendly bilayer composite film featuring an “outer oxygen-blocking/inner absorbing” architecture was designed. The outer layer was developed from a carboxymethyl cellulose–sodium alginate matrix cross-linked with 0.3% (w/w) citric acid to maximize oxygen impermeability, whereas the inner functional layer integrated 0.4% (w/w) nano-ZnO with 0.015% (w/w) powdered activated carbon (PAC) to endow UV-shielding capacity and to adsorb volatile lipid-oxidation products. At an optimized outer-to-inner mass ratio of 3:7, the bilayer film exhibited a tensile strength of 18.99 MPa, near-complete UV attenuation (>99%), water vapor permeability of 5.33 g m⁻² /(cm 2 48 h Pa), and oxygen transmission rate of 0.65 cm³ /(m²·day·bar). Additionally, the film demonstrated potent radical-scavenging activity against both DPPH (26%-71%) and •OH (83%-100%). Accelerated oxidation tests revealed that, relative to conventional polyethylene (PE) packaging, the composite film reduced acid value, peroxide value, and malondialdehyde content of walnut kernels by 28.18%, 16.53%, and 17.37%, respectively, during late storage, while markedly suppressing the formation of volatile aldehydes and acids. These findings establish a green and effective strategy for prolonging the shelf life of high-fat nuts.

Ga-doped zinc oxide (GZO) has attracted considerable interest for applications in electronic transport owing to its superior electrical properties. In this study, we report a low-temperature (<100°C) aqueous open-system route for the in-situ synthesis of GZO powders. The efficient substitutional doping of Ga 3+ into the ZnO lattice is achieved via a formation, in-situ transformation and dissolution–reprecipitation pathway of ε-Zn(OH) 2 or ZnGa-layered double hydroxide (ZnGa-LDH) intermediates, which simultaneously endows the products with unique flower-like or bundle-like morphologies. Chemical equilibrium calculations and time-dependent experiments reveal that the ionic species Zn(NH 3 ) 4 2+ and Ga(OH) 4 - , formed in the aqueous solution under high ammonia concentration, serve as reactive monomers that facilitate the formation and transformation of the intermediate phases. Electrical measurements combined with UV-Vis-NIR, EPR, and PL spectroscopic analyses indicate that Ga doping introduces shallow donor-type defects alongside zinc vacancy-related acceptor defects into the ZnO lattice, narrowing the optical bandgap and enhancing the electrical conductivity of the resulting powders. The GZO powder with a nominal doping ratio of 5% exhibits the lowest resistivity (Surface resistivity measured by the four-probe method is 3.43 × 10 4 Ω/□). This work provides a new pathway for the controllable preparation of functional conductive oxide powders.

Infection and excessive oxidative stress are major challenges in wound healing. Herein, quaternary electrospun membranes were fabricated using polylactic acid (PLA) and microcrystalline cellulose (MCC) as the matrix, with zinc oxide (ZnO) and curcumin (Cur) as functional additives to achieve dual antibacterial and antioxidant functions. MCC acted as a structural reinforcer and hydrophilic modifier to improve the mechanical properties and hydrophilicity of the PLA matrix, while ZnO and Cur served as synergistic bioactive components to endow the membranes with outstanding antibacterial and antioxidant capacities. ZnO-only groups (Z1 and Z2) exhibited moderate antibacterial and antioxidant activities. In contrast, the incorporation of Cur remarkably boosted these effects. The Z1C3 sample displayed a DPPH radical scavenging rate of 64.5%, alongside antibacterial efficiencies of 71.27% against Escherichia coli and 92.04% against S. aureus . Further elevation of ZnO and Cur loading yielded superior bioactivity; Z2C5 achieved antibacterial rates of 77.38% against E. coli , 95.68% against S. aureus , and a DPPH scavenging ratio of 89.98%. These results indicate that ZnO and Cur loading can be adjusted to balance bioactivity and safety. From the biosafety perspective, Cur greatly improved biocompatibility and reduced the hemolysis rate below 5%. Overall, the PLA/MCC/ZnO/Cur nanofibrous membranes hold promise as functional wound dressing materials, offering a potential strategy for the design of sustainable and multifunctional wound care materials.

Unpredictable variation of surface-enhanced Raman scattering (SERS) intensity, caused by uncontrolled interfacial adsorption, severely limits quantitative applications. To address this issue, the evolution of analyte adsorption states was systematically investigated on a 3D Au nanoparticles/ZnO nanoflowers (Au NPs/ZnO NFs) substrate. By correlating Raman signal fluctuations with finite element method (FEM) simulations, a four-stage interfacial adsorption model consisting of direct adsorption, indirect adsorption, saturation, and crystallization was established). Spatial volume integral evaluations reveal that during initial adsorption, capillary forces drive molecules to form an optimal monolayer within extreme nanogaps, thereby maximizing the utilization of hot spots and triggering a rapid signal surge. Conversely, excessive volume induces thick crystallization, leading to severe optical shielding and a global collapse of the localized electric field. Guided by this framework, the optimal linear dynamic range was defined, overcoming false-negative interference. Furthermore, the substrate achieved a 10-8 M limit of detection for Rhodamine 6G (R6G) and exceptional 15-minute photocatalytic self-cleaning. This study presents a high-performance, reusable SERS platform and establishes a universal physical framework that maps macroscopic sample volume to microscale adsorption dynamics, providing crucial guidelines for maximizing linearity and defining accurate dynamic ranges in practical SERS detection protocols.

The frequent occurrence of pesticides and nanoparticles in aquatic environments raises ecological concerns. Tebuconazole (TEB) is a widely used triazole fungicide, and zinc oxide nanoparticles (ZnO NPs) are one of the commonly used engineered nanoparticles. Both are frequently detected in the aquatic environment, yet their combined effects on aquatic organisms remain inadequately understood. In this study, we investigated the impacts of coexposure to environmentally relevant concentrations of ZnO NPs on the toxicity and bioaccumulation of TEB in zebrafish (Danio rerio). The 96-h median lethal concentration (LC50) of TEB to zebrafish was 6.45 mg/L. Coexposure to ZnO NPs (1–100 mg/L) led to a slight increase in acute toxicity of TEB. Long-term (28-day) coexposure to environmentally relevant concentrations of TEB and ZnO NPs exacerbated oxidative stress and apoptosis, decreased the activity of the detoxification enzyme carboxylesterase, and upregulated cytochrome P450 activity. Additionally, ZnO NPs did not enhance the accumulation of TEB but prolonged its clearance and altered its bioaccumulation pattern. These results indicate that the presence of ZnO NPs may increase the potential risk associated with TEB exposure in zebrafish, underscoring the need for further investigation of the interactive effects of pesticides and engineered nanomaterials in aquatic ecosystems.

A highly sensitive surface-enhanced Raman spectroscopy (SERS) method for the detection of acephate was established by using the substrate of silver nanoparticles (AgNPs) modified with N-acetyl-L-cysteine (NAC) and zinc oxide (ZnO). The Raman signal enhancement factor (EF) of acephate by the substrate of ZnO/NAC/AgNPs can be reached 4.95 × 10 6 . The ultraviolet-visible spectroscopy (UV-vis), high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), zeta potential, Fourier transform infrared spectra (FT-IR) and thermogravimetric analysis (TGA) were used to characterize the substrate of ZnO/NAC/AgNPs. The mechanism of electromagnetic enhancement (EM) assisted by chemical enhancement (CM) was elucidated in detail. The optimal experimental conditions were selected. The interference experiments showed that this method had high selectivity in complex substrates. There was a good linear relationship between acephate concentration and SERS signal intensity in the range of 6.00 × 10 −9 mol L −1 – 8.00 × 10 −7 mol L –1 , and the linear equation was I SERS = 85.02 c + 24712.49 ( r = 0.9982, c : nmol L −1 ) with the limit of detection (LOD) was 3.40 nmol L –1 (3 σ / S ). The SERS method was successfully applied for the detection of acephate residues in vegetable samples, and the recovery was in the range of 95.3% – 104% ( n = 5).

Flexible and wearable gas sensors are drawing more attention in monitoring air quality and human health. Concurrently, high response, low operation-temperature, and long-term stability are highly required for the gas sensors. Herein, an aramid nanofiber (ANF)-based ammonia (NH 3 ) flexible gas sensor with high response, room temperature stability and low detection limit was prepared. The competitive performances of the gas sensor were achieved by well-constructed MXene@ZnO heterojunctions on ANF aerogel. The obtained ANF/MXene@ZnO flexible gas sensor contributed to a response value of 1 ppm NH 3 as high as 150.7% at room temperature. Furthermore, the sensor also exhibited good long-term stability for 50 days. The excellent NH 3 sensing performances of the flexible ANF/MXene@ZnO sensor is attributed to its high surface area, abundant reaction sites, and the formation of MXene@ZnO heterojunction. The metal-like properties of MXene can provide a variety of electron transport channels, speeding up the electron transport rate. In addition, adsorption of more NH 3 molecules can also enhance the sensitivity of sensitive materials. According to our density functional theory calculations, the adsorption of NH 3 by MXene@ZnO in the materials we studied can reach −1.54 V. This indicates that MXene@ZnO has a strong affinity for NH 3 and can effectively capture NH 3 molecules and increase the response value. This work is expected to afford an effective strategy for designing high-performance flexible gas sensors at room temperature.

Drug delivery systems utilize micro-nanomaterials as drug carriers, encapsulating drugs within micro-nanoparticles and releasing them to target tissues or cells via specific pathways. This technology enhances drug stability, prolongs drug retention time in the body, and reduces damage to healthy tissues. This study successfully synthesized novel carbon-doped zinc oxide (C/ZnO) micro-nanomaterials and employed polydopamine (PDA) for surface modification, resulting in the construction of C/ZnO/PDA carriers. Experimental results demonstrate that PDA modification significantly enhances the drug delivery performance of the material. This composite material exhibits a 5-Fu loading efficiency of 37.8%, representing a 1.15-fold increase compared to unmodified C/ZnO. In vitro release tests demonstrate sustained drug release characteristics, showing a 1.62-fold increase over the unmodified system. In addition, these medicine particles significantly enhanced the indicators of antibacterial and bactericidal efficacy. In vitro cell experiments also confirmed that the drug carrier can enhance the lethality of the drug against HepG2 cells. Research on the binding energy between the carrier and the drug revealed that PDA modification promotes drug-carrier binding, resulting in more stable overall adsorption. These findings demonstrate the potential application value of micro-nanoparticle-based targeted drug delivery systems in disease prevention and treatment.
