Lithium sodium silicate glasses containing ZnO with nominal composition (25-x) Li 2 O- xZnO-10Na 2 O-65 SiO 2 (mol%) (Where x = 0, 5, 10, 15, 20 and 25 mol%) were effectively synthesized using the melt quenching method. The impact of ZnO/Li 2 O replacement on the glass structure, physico-mechanical and radiation shielding performance was evaluated. Results from various physical properties, such as molar volume Vm and oxygen packing density (OPD), are consistent with a progressive change in the glass network as Li 2 O is replaced by ZnO. These trends suggest a reduction in network cohesion, though this interpretation is based on calculated physical parameters. FTIR results are consistent with ZnO incorporation into the silicate network. Zn–O bonds have lower dissociation energy than Si–O bonds, and the calculated mechanical moduli decrease with increasing ZnO content, consistent with the expanding molar volume and declining atomic packing density observed across the series. Peak deconvolution of the FTIR spectra reveals a shift in the low-frequency band from 515 cm −1 in ASZ0 to 473 cm −1 in ASZ25, consistent with increasing Zn–O vibrational contributions with ZnO content. All shielding parameters were theoretically calculated and evaluated using Phy-X/PSD software in the energy range between 0.015 and 15 MeV, and the results indicate that adding ZnO at the expense of Li 2 O leads to an improvement in the calculated shielding efficiency of the prepared glasses. The calculated photon-shielding parameters indicate that adding ZnO at the expense of Li 2 O improves the attenuation performance of the prepared glasses across the studied energy range. Experimental validation through direct gamma-ray transmission measurements is recommended in future work.

ZIF-8-derived ZnO/CoFe 2 O 4 removes 99.12% ciprofloxacin in 6 min under visible light. • Type II band alignment drives directional electron transfer, suppressing carrier recombination. • Dual-channel PMS activation via photoelectron reduction and Co/Fe redox cycling. • Over 99% efficiency retained after five cycles in actual surface water and groundwater. Fluoroquinolone antibiotics in aquatic environments threaten ecosystems and human health by spreading antimicrobial resistance. This study synthesized a magnetically recoverable ZnO/CoFe 2 O 4 heterojunction using ZIF-8-derived porous ZnO as substrate via solvothermal method. The optimized composite achieved 99.12% ciprofloxacin removal within 6 min under visible light with peroxymonosulfate. XPS evidence supports Type II heterojunction formation with directional electron transfer with directional electron transfer from ZnO to CoFe 2 O 4 . A dual-channel PMS activation mechanism is proposed involving direct PMS reduction by photogenerated electrons and SO 4 ⁻ generation through Co 2 ⁺/Co 3 ⁺ and Fe 2 ⁺/Fe 3 ⁺ redox cycles. EPR identified 1 O 2 and SO 4 ⁻ as dominant reactive species. The catalyst maintained excellent stability with over 99% efficiency after five cycles. LC-MS revealed piperazine ring cleavage, decarboxylation and defluorination pathways leading to deep oxidative degradation. This work provides an efficient strategy for antibiotic wastewater treatment using magnetically separable photocatalysts with synergistic photo-oxidation and persulfate activation capabilities.

Achieving gas sensors that exhibit excellent sensitivity, selectivity, and rapid response to volatile organic compounds (VOCs) is critically important for effective environmental monitoring applications. In this research, a novel Eu-doped Tourmaline @MOF-ZnO core-shell nanocomposite was designed and fabricated, integrating a MOF-derived porous ZnO shell, a spontaneously polarized tourmaline core, and rare-earth Eu doping. The gas sensing properties of the sensors were systematically investigated across three different test scenarios: (i) at high temperature in the dark, (ii) at high temperature with UV enhancement, and (iii) at room temperature with UV activation. The optimized 0.08 wt% Eu-5 wt% TML-ZnO sensor achieved an exceptional response of 536 to 100 ppm n-butanol at room temperature under UV activation. The response value exceeds that of the pristine MOF-ZnO sensor by a factor of 14.78. Furthermore, the sensor exhibited rapid response/recovery times (39 s and 23 s, respectively), outstanding selectivity and long-term stability, superior detection capability for ultra-low gas concentrations (LOD = 23.35 ppb). This study pioneers a synergistic UV-activated rare-earth doping strategy for TML@MOF-ZnO core-shell nanostructures, enabling room-temperature ppb-level VOCs sensing.

By adjusting the ZnO content to modulate the glass network structure, self-crystallization of the CsPbBr 3 QDs in borosilicate glass was induced. • The prepared CsPbBr 3 QDs@glass exhibits an IQE and EQE of 39.8% and 29.6% upon 455 nm excitation, respectively. • The prepared CsPbBr 3 QDs@glass demonstrates favorable thermostability and water‑resistant performance. CsPbBr 3 perovskite quantum dots (QDs) are ideal candidate materials for next generation wide color gamut displays, yet their practical application has been hindered by inherent instability. This study achieves in-situ self-crystallization of highly stable and efficient CsPbBr 3 QDs in borosilicate glass (CsPbBr 3 QDs@glass) using ZnO as a glass intermediate oxide. Spectroscopic analyses (FT-IR, Raman, and XPS) reveal that Zn 2+ ions disrupt rigid Si-O-Si and B-O-B bonds to form weaker Zn-O-Si linkages, driving a [BO 4 ] to [BO 3 ] coordination transition. This depolymerization process creates a looser glass network enriched with non-bridging oxygen (NBO), significantly reducing steric hindrance and providing sufficient space for CsPbBr 3 QDs growth. The doping concentration was optimized to 12 mol% ZnO to balance the trade-off luminescence performance between network relaxation and concentration quenching. The optimized sample exhibits an internal quantum efficiency (IQE) as high as 39.8% upon 455 nm excitation. Notably, the CsPbBr 3 QDs@glass retains 52.1% of its initial intensity at 373 K and exhibits negligible attenuation upon cooling. Furthermore, it preserves approximately 97.0% of its luminescence performance even after 10 days of water immersion. Finally, a white LED backlight strip fabricated with the composite exhibits a wide color gamut reaching 124.2% NTSC and 89.4% Rec. 2020 coverage. Assembled into a display screen prototype, the device produces significantly more saturated, vivid green tones than mainstream commercial displays.

ZnO-based pigments doped with Co and Mn ions were synthesized via a self-propagating combustion method using Gingko biloba leaves as a bio-derived fuel. Thermogravimetric analysis confirmed an effective combustion interaction between the metal nitrates and the leaf-derived fuel, validating the combustion synthesis process. X-ray diffraction results revealed the formation of single-phase hexagonal wurtzite ZnO for all samples, with successful incorporation of dopant ions without secondary phase formation. The synthesized powders exhibited porous agglomerated morphologies resulting from gas evolution during the combustion process, while FTIR analysis confirmed the formation of Zn–O bonds and the effective removal of organic species after calcination. Optical characterization demonstrated that transition-metal doping significantly modifies the visible and near-infrared reflectance properties of ZnO pigments, producing green Co-doped and black-brown Mn-doped pigments with relatively high NIR solar reflectance. These results indicate that bio-fuel-assisted combustion synthesis provides a simple and effective route for producing functional ZnO-based pigments with tunable optical properties for potential application in thermally functional coating materials.

A ternary ZnO/CuO/cellulose-derived carbon (CBC) heterostructure was synthesized via a one-step hydrothermal process for efficient room-temperature detection of ammonia (NH 3 ) with effective selectivity. The integration of n-type zinc oxide and p-type copper oxide within the conductive CBC network facilitates rapid charge transfer while providing abundant adsorption sites. Characterization by XRD, XPS, and TEM confirmed the presence of crystalline ZnO and CuO species uniformly dispersed throughout the porous CBC matrix. The composite sensor demonstrated a response value of 29.2% to 100 ppm NH 3 , with rapid response and recovery times (38 s and 41 s). UV-Vis diffuse reflectance spectroscopy indicated a reduced bandgap (3.10 eV), suggesting enhanced visible-light absorption and improved charge separation. The sensor exhibited reasonable repeatability over a 30-day continuous detection cycle in a 200 ppm ammonia environment. In addition, the sensor maintained stable response characteristics over five consecutive sensing cycles at 200 ppm NH 3 . The synergistic effect of p-n heterojunctions combined with the conductive CBC framework effectively enhances surface reactivity. Meanwhile, although the composite features a flexible and biodegradable carbon backbone, its integration potential for wearable Internet of Things (IoT) devices remains to be thoroughly investigated, and further optimization of mechanical endurance is required before practical application. Overall, this low-cost, eco-friendly composite meets the urgent demand for timely ammonia detection in areas such as environmental assessment.

In this study, a novel ternary photocatalyst, composed of BiOCl, ZnS, and ZnO, was successfully prepared for the first time via a mixed method followed by thermal treatment, which possessed a dual Type-II heterojunction structure. This composite exhibited substantially boosted photocatalytic degradation efficiency toward tetracycline (TC) under simulated sunlight. The microstructure, crystal morphology, charge transfer properties, and optical absorption behavior of the composite were systematically characterized and analyzed. The results demonstrated that the dual type-II heterojunction formed among ZnS, ZnO, and BiOCl effectively broadened the light absorption range and promoted the separation of photogenerated carriers, thereby significantly enhancing the photocatalytic activity. Active species trapping experiments and ESR tests confirmed that ·OH and ·O 2 - were the main active species in this photocatalytic system. The degradation efficiency of TC by this ternary catalyst under visible light reached as high as 95.8%, and it still maintained excellent stability after five consecutive cycles. Band structure analysis further revealed the charge separation mechanism in the dual type-II heterojunction. This novel dual type-II heterojunction is expected to provide new insights into the efficient degradation of pharmaceutical pollutants.

The advancements in flexible display technology impose stringent demands on the optical properties and environmental stability of perovskite luminescent materials. Addressing the core challenges of poor environmental stability and optical performance degradation in methylammonium lead bromide (MAPbBr 3 ) quantum dots, this study proposes a dual-stability strategy combining “internal crystallization regulation” with “external physical protection.” A ZnO/MAPbBr 3 /PVDF composite film was prepared through synergistic modification with zinc oxide (ZnO) and polyvinylidene fluoride (PVDF), with the optimal ZnO content identified as 40 μL. Under these conditions, the composite film exhibited a green light emission full width at half maximum (FWHM) as low as 19.88 nm and a photoluminescence quantum yield (PLQY) of 76.06%, demonstrating high color purity. After heating at 100°C for 60 min, the PL intensity decayed by only 30%, and after 168 h of immersion in water, it retained 65% of its initial PL intensity, indicating significantly enhanced environmental tolerance. When this film served as the green conversion layer integrated with red CsPbI 3 quantum dot films and GaN blue LEDs to form a white light-emitting diode (WLED), the device achieved a color gamut coverage of 126% of the NTSC standard and 94% of the Rec. 2020 specification. Research indicates that ZnO enhances crystalline integrity by regulating MAPbBr 3 nucleation and growth, while PVDF forms a compact hydrophobic barrier. Their combined effect enhances both the film’s optical performance and environmental stability, enabling WLEDs with ultrawide color gamut that meet the requirements of high-performance flexible display and lighting applications.

In this paper, five self-emulsifying organic–inorganic ZnO core-shell structure sizing agents with different amounts of coupling agent KH570 bonding on their shells were synthesized. These agents exhibited uniform particle size in the range of 90–250 nm, excellent storage stability and enhanced thermal stability up to 300°C, while also demonstrating an effective reactivity with carbon fibers (CF). The reactive sizing agents modified by KH570 not only significantly increased the monofilament tensile strength, the surface roughness and the surface energy of the sized CF, reaching 6837.35 MPa, 23.81 nm and 80.2 mJ/m 2 , but also prominently enhanced the interlaminar shear strength (ILSS) and flexural strength of the sized CF/epoxy resin (CF/EP) composites, approaching 141.43 and 2087.86 MPa, corresponding improvement of 26.49%, 297.50%, 89.20%, 60.81%, and 40.22%, respectively, compared to the unmodified sizing agents with KH570. The improvements in mechanical properties are mainly attributed to the increased wetting of EP matrix on the sized CF and the enhanced interfacial adhesion between CF and the sizing agent, facilitated by chemical bonding of the KH570 modified ZnO particle shell on the CF surface and their crosslinking of the sizing agents among themselves, and efficient stress transfer at the CF/EP interface through the interlocking mechanism of the organic–inorganic ZnO core-shell particles. Highlights The sizing is modified by KH570 to form a reactive sizing. The reactive sizing undergoes surface reactions on CF to enhance their adhesion. The crosslinking on sizing surface affects composite mechanical properties. The composite has a maximum ILSS of 141.43 MPa. The composite has a maximum flexural strength of 2087.86 MPa.

To address the low carrier separation efficiency and insufficient response of pristine β-Ga 2 O 3 -based solar-blind ultraviolet photodetectors, a low-cost, non-vacuum heterostructure strategy was proposed. β-Ga 2 O 3 thin films were prepared by mist chemical vapor deposition, and ZnO layers were deposited via successive ionic layer adsorption and reaction to construct an Au/β-Ga 2 O 3 /ZnO/Au heterojunction photodetector. Material characterization verified a clean heterointerface without impurity phases, and the built-in electric field significantly promoted carrier separation. Under 254 nm illumination at 40 V bias, the device delivers a photocurrent of 3.94 μA, 20 times higher than the pristine β-Ga 2 O 3 detector. The responsivity reaches 10.98 A/W, detectivity is 3.69×10 12 Jones, and external quantum efficiency is up to 5.36×10 3 %, enhanced by 20, 19, and 23 times respectively, with markedly improved rise speed and stable switching response. Moreover, the device shows a good linear relationship (R 2 =0.98115) between photocurrent response and bovine serum albumin concentration, enabling highly sensitive protein detection. This work provides a low-cost route for high-performance β-Ga 2 O 3 solar-blind photodetectors and extends their application to rapid, non-destructive UV biosensing.

The escalating emissions of nitrogen dioxide (NO 2 ) resulting from rapid industrialization pose a severe threat to both ecological balance and public health, rendering the development of high-performance NO 2 sensors imperative for precise environmental monitoring. However, conventional metal oxide semiconductor (MOS) sensors based on pristine materials suffer from intrinsic limitations, including low sensitivity, poor humidity tolerance, and high operating temperatures. Single-mode modification strategies often fail to simultaneously mitigate these drawbacks. Herein, we propose a synergistic modification strategy combining rare-earth doping with heterojunction engineering. Ce-doped SnO 2 /ZnO nanocomposites were successfully synthesized via a facile hydrothermal method. Among the fabricated devices, the S 5 CZ 5 sensor (1:1 mass ratio) exhibited superior performance, delivering a robust response of 55.3 to 100 ppm NO 2 at 180 °C, accompanied by rapid response/recovery kinetics (21 s/29 s) and a low theoretical detection limit of 843 ppb. Notably, the incorporation of Ce effectively modulated surface wettability, endowing the sensor with exceptional moisture resistance and long-term stability. Furthermore, density functional theory (DFT) calculations elucidated the atomic-scale mechanism: the ternary SnO 2 /Ce-ZnO system yields an exceptionally high NO 2 adsorption energy (−2.55 eV) and a massive interfacial charge transfer (0.49 e), while critically suppressing H 2 O interactions (adsorption energy of −0.40 eV, restricted charge transfer of 0.13 e), as corroborated by charge density difference analyses. Coupled with an optimized density of states near the Fermi level, this work achieves a multidimensional enhancement of sensing performance, offering novel insights for trace gas detection in complex environments.

To develop active packaging for extending the shelf life of perishable fruits like strawberries, this study fabricated a multifunctional nanocomposite film. The film was based on a linear low-density polyethylene/cyclic olefin copolymer (LLDPE/COC) blend to provide a high barrier matrix, into which zinc oxide nanoparticles (ZnO NPs) modified with the silane coupling agent KH-570 were incorporated to impart antibacterial functionality. The modified ZnO NPs showed improved dispersion within the polymer matrix as confirmed by SEM analysis. The resulting blown films exhibited enhanced comprehensive properties. Notably, the optimal film (LLDPE/COC/ZnO-1) achieved a tensile strength of 34.75 MPa and an elongation at break of 1189.03%. Compared to the pristine blend film, the nanocomposite film demonstrated a reduction of 7.35% in water vapor transmission rate (WVTR) and 2.5% in oxygen transmission rate (OTR). Critically, the film demonstrated strong antibacterial activity, showing inhibition rates of approximately 90.69% against Escherichia coli and 92.16% against Staphylococcus aureus . In practical strawberry preservation tests, the nanocomposite packaging effectively slowed down decay, weight loss, and softening, extending the shelf life by 3 days compared to conventional polyethylene packaging. This work presents a promising strategy for designing high-performance, multifunctional food packaging materials. Graphical KH-570 modified nano-ZnO was incorporated into an LLDPE/COC blend via blow molding. The optimal nanocomposite film (1 wt% ZnO) exhibited enhanced mechanical strength, barrier properties, UV-shielding, and antibacterial activity, successfully extending strawberry shelf life by 3 days. This work provides a promising strategy for multifunctional active food packaging.
