Accurate detection of ammonia (NH 3 ) is a key indicator for evaluating the deterioration of high-protein foods and is of great significance for food safety. In this study, we modified Sn-ZnO using a Co-based metal–organic framework (MOF) material (ZIF-67) to prepare cauliflower-shaped Sn-ZnO/ZIF-67 (SZZ67) for NH 3 sensors at room temperature (25 °C). By regulating Co 2+ , it was found that the sensor's response to NH 3 decreased with the increase in Co 2+ content, while the desorption ability was significantly enhanced. When the mass ratio of Sn-ZnO to the added C 4 H 6 CoO 4 ∙4H 2 O was 1:1, its response was 13.46 times that of Sn-ZnO, the response/recovery time was 63.78/7.99 s, and good moisture resistance was observed. Density functional theory (DFT) confirmed that SZZ67 can adsorb more NH 3 and release more conductive electrons, thereby increasing its response value. The sensors prepared using SZZ67 could more effectively monitor NH 3 , which is applicable for monitoring the freshness of soy products.

Soft magnetic composites (SMCs) have attracted significant attention as key magnetic materials with the ongoing trend toward high-frequency operation in electronic devices. However, conventional approaches to tailoring the magnetic properties of SMCs rely excessively on coating processes, highlighting an urgent need to develop new control strategies. In this work, the influences of silicone resin content and annealing temperature on the microstructure and soft magnetic properties of FeSiBCuNb nanocrystalline soft magnetic composites (NSMCs) were systematically investigated. During annealing, the thermal decomposition of silicone resin generates a SiO 2 insulating layer. Concurrently, part of the oxygen released from the decomposition of both the silicone resin and zinc stearate reacts with Fe in the FeSiBCuNb powder to form a uniform Fe x O y insulating layer, while the remaining oxygen reacts with Si to generate SiO 2- y . The dual-layer SiO 2 /Fe x O y insulating structure effectively suppresses magnetic losses. Moreover, annealing induces the precipitation of the α-Fe(Si) phase from the amorphous matrix, and the volume fraction and size of the α-Fe(Si) phase increase with increasing the annealing temperature, whereas excessive grain coarsening leads to the deterioration of magnetic properties. The NSMC with a silicone resin content of 1.5 wt% annealed at 450 °C gets remarkable comprehensive magnetic properties with a high effective permeability ( μₑ ) of 37.76, excellent frequency stability up to 1 MHz, and a DC bias performance of 51.82 % at 100 Oe. This work provides valuable insights for the development and application of novel high-performance SMCs by optimizing the coating process and tailoring the nanocrystalline structure.

Modulating the electromagnetic properties of Ti 3 C 2 T x MXene to produce an ideal multifunctional and efficient microwave absorbent is a challenging research hotspot. Although the atomic layer deposited transition magnetic metal nanostructures are a feasible strategy, the effects of the components and microstructure of the introduced magnetic nanostructure on the electromagnetic wave absorption performances of the MXene are still far from clear. Here, the Fe element has been selected as the modifier, and a heterostructure Fe/Ti 3 C 2 T x MXene hybrid is constructed by the atomic layer deposition of Fe nanoparticles on the Ti 3 C 2 T x nanosheets. The influences of the deposition cycles on the chemical composition, microstructure, electromagnetic response characteristics, and microwave absorption properties are investigated. The results show that the decoration of Fe nanoparticles enables a tunable electromagnetic performance. The Fe/Ti 3 C 2 T x MXene hybrid achieves an optimal attenuation with the minimum reflection loss of -82.94 dB at a small thickness of 1.16 mm, corresponding with an effective absorption bandwidth of 3.76 GHz. The strong microwave absorption is attributed to the dielectric-magnetic synergy in the MXene and Fe nanoparticles, which provides excellent impedance matching, interfacial and dipolar polarization loss, and magnetic resonance loss. Specifically, the hybrid endows a low Fe content of 2.66 wt%. This is important for the design of a lightweight absorber with high attenuation efficiency.

Cyclopentanone (CPO) as a key raw material has been widely applied in spices, pharmaceuticals, and sustainable fuels. The catalytic conversion of biomass-derived furfural (FAL) to CPO meets the requirements of sustainable development goal but still be challenging because of the relatively low selectivity of CPO in the complex tandem catalytic processes. Herein, a Ni/WO 3 -H 2 catalyst presents a cooperative interface that possesses hetero-valent interface of Ni 0 (metallic) and Ni 2+ (interfacial NiWO 4 ), oxygen vacancies (O v ), and acid sites simultaneously was prepared and applied in the tandem hydrogenative ring-rearrangement of FAL to CPO. Under 160 °C and 3 MPa of initial hydrogen pressure, the catalyst achieved 90.3 % furfural conversion and 96.9 % selectivity to CPO, with a turnover rate of 4.26 mmol·g cat ⁻¹ ·h⁻¹ . Moreover, the Ni/WO 3 -H 2 catalyst demonstrated excellent stability and recyclability. Further investigation on reaction mechanism shows that the synergy of each active site, Ni 0 , Ni 2+ (NiWO 4 ), oxygen vacancies (O v ), and acid sites, promotes the conversion of FAL to CPO and effectively avoids the undesired side reaction. Accordingly, a multi-site cooperative mechanism is proposed: FAL hydrogenates to FOL on Ni 0 sites; acid sites rearrange FOL to HCP, which dehydrates at O v sites to CPE; ultimately, CPE is hydrogenated to CPO on Ni hetero-valent interface.

Electrochemical self-reconstruction is a critical process in transition metal-based electrocatalysts, as it governs the generation of catalytically active species during the oxygen evolution reaction (OER). In the NiMoO 4 system, γ-NiOOH is recognized as the truly active species, however, its slow and shallow reconstruction severely limits catalytic performance. Herein, a Fe doping strategy is employed to accelerate the in situ self-reconstruction kinetics of NiMoO 4 . A series of Fe-doped NiMoO 4 catalysts were synthesized via a one-step hydrothermal method, and the influence of Fe doping on the structural evolution and catalytic mechanism of the materials was systematically investigated. Fe incorporation induces preferential exposure of low-index crystal planes and lattice distortion, which facilitates selective Mo leaching and modulates the electronic structure of Ni. This synergistic effect not only enhances the extent but also accelerates the rate of self-reconstruction, thereby promoting the formation of low-crystallinity γ-NiOOH and consequently activating the lattice oxygen mechanism (LOM). As a result, 30 %Fe-NiMoO 4 -R exhibits a low overpotential of 205 mV@10 mA cm −2 , with stability for 400 h at 50 and 100 mA cm −2 . This work clarifies the role of Fe doping in tuning reconstruction dynamics and provides valuable insights into the design of efficient OER catalysts via lattice oxygen activation.

The development of efficient photocatalytic systems for hydrogen peroxide (H 2 O 2 ) production from pure water remains a huge challenge due to rapid charge recombination and insufficient redox capability in single-component photocatalysts. Herein, we successfully constructed the S-scheme oxygen-vacancy-enriched MoO 3 quantum dots (Ov-MoQDs)/sulfur-vacancy-rich Zn 3 In 2 S 6 (Sv-ZIS) heterostructures by coupling Sv-ZIS nanosheets with Ov-MoQDs. The optimized 3Ov-MoQDs/Sv-ZIS sample achieves an outstanding H 2 O 2 production rate of 85.8 ± 3.1 μM under visible light illumination for 1 h in the pure water, which is about 3.5 and 45.1 times higher than those of Sv-ZIS and Ov-MoQDs, respectively. Through comprehensive in situ and ex situ characterizations combined with theoretical calculations, we demonstrate that the enhanced activity stems from efficient charge separation and transfer across the heterogeneous interfaces via an S-scheme mechanism. Furthermore, the H 2 O 2 photosynthesis over Ov-MoQDs/Sv-ZIS heterostructures is found to proceed through a two-step single-electron oxygen reduction reaction (ORR) pathway. This work provides valuable insights into the rational design of advanced heterostructured photocatalysts for sustainable chemical synthesis.

High pixel resolution is critical for next-generation quantum-dot light-emitting diode (QLED) display technologies. Although advances in quantum-dot patterning have improved resolution, the reduction in pixel size often degrades emission efficiency and pattern uniformity. Here we develop a nanoimprint strategy using nanohole-array moulds to fabricate nano-QLEDs via capillary action-induced self-assembly of quantum dots. We realize pixels as small as sub-100 nm with ultrahigh pixel resolution up to 169,333 pixels per inch over an electroluminescent area of 4 mm 2 . Benefiting from the closely packed light-emitting quantum-dot monolayers, our nano-QLEDs show minimal performance degradation upon reducing the pixel size. Notably, the smallest red, green and blue nano-QLEDs maintain average external quantum efficiencies of 17.0%, 10.5% and 5.7%, respectively. We also demonstrate fabrication on flexible substrates as well as an active-matrix display by imprinting micro-QLEDs on a thin-film-transistor backplane, showing images and videos with a resolution of 100 pixels × 180 pixels. This work provides a powerful method for fabricating ultrahigh-resolution nano-QLED arrays with high external quantum efficiency for next-generation displays.

Catalysts with high-efficient performance, high durability and low cost are still urgently needed to promote the wide application of direct alcohol fuel cells (DAFCs). This work prepared a PdNi/PPy composite by dispersing Ni-doped Pd nanoparticles on coarse polypyrrole (PPy) granules via facile interfacial redox and polymerization. The optimized PdNi/PPy composite possesses a porous morphology and uniform dispersion, which are key for achieving performance synergistic optimization in alcohol oxidation reactions (AORs). Specifically, for ethylene glycol oxidation (EGOR), the PdNi/PPy achieves mass activity (MA, 5577.2 mA mg Pd −1 ), specific activity (SA, 32.3 mA cm −2 ), and intrinsic activity (TOF, 6.8 s −1 ), which are 7.9, 3.0 and 2.7 times those of commercial Pd/C, respectively. It also exhibits higher activity for ethanol and methanol oxidation compared to other catalysts. Characterizations demonstrate that the synergy between Ni-doped Pd and conductive PPy significantly enhances catalytic properties. The electronic structure of Pd is optimized via Ni-doping induced d-band center modulation and efficient interfacial charge transfer through heterojunction formation. Additionally, the PPy support facilitates uniform dispersion and maximizes active site exposure. This work can offer meaningful insights for the development of advanced anode catalysts by effective doping of active metals and further strengthening of the carrier effects for DAFCs.

Solar-driven interfacial evaporation has become a highly promising approach to mitigate freshwater scarcity. However, developing green and sustainable solar evaporators that effectively balance heat localization and salt rejection remains a major challenge for real-world applications. Herein, inspired by the radial hierarchical microchannels in coral skeletons, we constructed a biomimetic evaporator (CRFB 6 -Gel@MC) by functionalizing coconut residue fiber-based aerogel (CRFB 6 -Gel) with solar-thermal composite (MXene@CDs, MC). The CRFB 6 -Gel@MC evaporator enabled simultaneous continuous water transport and salt reflux while preventing heat dissipation to bulk water, demonstrating effective decoupling of the long-standing conflict between salt rejection and heat localization. Under 1 sun illumination, the CRFB 6 -Gel@MC demonstrated a high evaporation rate of 4.66 kg·m −2 ·h −1 (65% higher than traditional evaporator with vertically aligned channels) and 91.3% solar-to-vapor efficiency. In addition, the evaporator exhibited zero salt crystallization after 8 h at 3-sun intensity in 20 wt% brine, validating its long-term operational stability. This work not only demonstrates the untapped potential of agricultural waste valorization but also establishes a biomimetic design paradigm for high-efficiency solar desalination systems.

Conductive gels hold significant promise for applications in flexible sensing and wearable electronics, yet face the challenge of limitations in mechanical strength and environmental stability. Herein, a facile and effective strategy was proposed to fabricate high-performance eutectogels by introducing metal-based deep eutectic solvent (MDES) consisting of zinc chloride (ZnCl 2 ), ethylene glycol (EG), and acrylic acid (AA) into the wood skeleton (WS), which was extracted from natural wood, followed by in-situ ultraviolet (UV)-initiated polymerization. The resulting metal-based deep eutectic solvent/wood skeleton eutectogels (MDES/WS eutectogels) exhibited high ionic conductivity (2.82 × 10 –2 S/m), higher than most conventional wood-based gels, benefiting from the inherent conductivity of the MDES, as well as the aligned micro and nanochannels in WS that facilitate ion transport. Moreover, the synthesized polyacrylic acid (PAA) network could form strong interfacial interactions with the cellulose nanofibers through hydrogen bonding and Zn 2+ coordination cross-linking, significantly reinforcing the eutectogels with a high tensile strength of 41.50 MPa and toughness of 8.4 MJ/m 3 , while still demonstrating good environmental stability (–60 to 100 °C). Leveraging its high conductivity, robust mechanics, and environmental stability, the developed eutectogels functioned as flexible sensors to generate stable and responsive electrical signals during simulated human movements and possessed potential as a programmable information transmission interface through Morse code input. This work established a novel paradigm for developing sustainable, mechanically robust, and environmentally stable conductive gels, offering a versatile platform for next-generation flexible electronics operable under extreme conditions.

Photocatalytic three-electron oxygen reduction (3e - ORR) can convert dissolved O 2 into •OH via coupled 2e - /1e - steps, bypassing external H 2 O 2 dosing and the kinetic bottleneck of conventional photo-self-Fenton (PSF) systems. Here, Fe-substituted phosphomolybdate clusters (FePMo) are anchored on a biomass-derived hierarchical tubular carbon (HTCC) to form an HTCC/FePMo heterojunction (HFe) that drives a visible-light self-Fenton process. For tetracycline (TC, 10 mg L −1 ), HFe achieves 99 % removal within 120 min at unadjusted pH 0 = 5.8 ( k obs = 0.026 min −1 ) and 3.6–7.7-fold higher mineralization than either component, while retaining high activity from pH 3–9 and in saline water, natural surface water, and secondary effluent. In a continuous-flow reactor, an HFe/PVDF membrane (0.64 mg cm −2 loading; 2 mL min −1 , HRT 1.23 min) sustains > 90 % TC removal for 120 h. Ecotoxicity is alleviated, with inhibition-zone diameters shrinking from ∼2.3 to ∼0.8 cm ( S. aureus ) and from ∼1.25 to ∼0.7 cm ( E. coli ), and wheat-leaf Fv/Fm recovering to ∼0.73, comparable to the water control. The energy demand is low (EE/O = 0.0031 kWh L −1 ; EE/M = 0.31 kWh g −1 ), supporting a scalable, sustainable route for advanced treatment of refractory wastewater.

In this study, the polysaccharide from poplar sap liquid fermented by Sanghuangporus vaninii mycelium (PFP) was extracted via ultrasonic-assisted extraction and further purified using DE-52 cellulose anion-exchange resin to obtain the acidic polysaccharide fraction (APFP). Subsequently, APFP was blended with chitosan (CS) to fabricate a series of composite films with APFP concentrations of 0.25%, 0.5%, 0.75%, and 1% (W/W). Pure CS films were used as controls. The mechanical, barrier, and optical properties, microstructure, and thermal stability of the films were systematically characterized. Meanwhile, their water contact angle, particle size, zeta potential, antioxidant activity, antibacterial activity, and preservation performance for blueberries stored at room temperature were also evaluated. Compared with CS films, APFP-CS films incorporated with APFP exhibited darker color and enhanced mechanical properties. Additionally, the addition of APFP enhanced the antioxidant and antibacterial properties of the CS films. The weight loss rate, decay rate, hardness, soluble solids content, titratable acid content, malondialdehyde (MDA) content, vitamin C (VC) content, anthocyanin content, and total bacterial counts of the blueberries were measured. These results indicated that APFP incorporation could endow CS films with favorable functional properties and bioactivity, and extend the shelf life of blueberries to 15 days. Therefore, the APFP-CS composite films are a promising packaging material for food preservation.
