This study developed a multifunctional freshness indicator film based on black wolfberry anthocyanins (BWA) and a Houttuynia essential oil Pickering emulsion for monitoring pork freshness. The film was fabricated using a polyvinyl alcohol/guar gum blend system via a casting method, followed by screen-printing of a chitosan-stabilized Houttuynia essential oil Pickering emulsion onto its surface. The film showed improved mechanical strength (tensile strength up to 32.35 MPa) and ammonia-responsive color change from purplish-red to bluish-green during 4 °C pork storage, correlating with TVB-N (17.73 mg/100g) and TVC (5.98 lg CFU/g) by day 6. Structural analyses (SEM, FTIR, XRD) confirmed hydrogen bonding and enhanced film compactness. A ResNet18 model trained on 305 film images achieved 97.3% classification accuracy and was integrated into a PyQt5-based visual platform. This work integrates natural pigments, antibacterial Pickering emulsions, and deep learning for real-time meat freshness monitoring. However, the film's color stability under prolonged storage and its sensitivity to environmental humidity require further optimization. Future studies should focus on scaling up production and validating the system for diverse meat products under varying storage conditions.

In deep oil and gas drilling, high-temperature and high-salinity conditions have posed severe challenges to water-based drilling fluids. These harsh environments can impair the performance of drilling fluids, increase fluid loss, and lead to frequent downhole accidents. In view of the above problems, this study combines the advantages of zwitterionic and hydrophobic association to prepare a zwitterionic hydrophobic association polymer (P-DADL) with high temperature and salt resistance. The chemical structure and properties were characterized and evaluated by in-situ infrared spectroscopy, nuclear magnetic resonance, thermogravimetry, SEM and other experimental methods. The results show that the thermal decomposition temperature of P-DADL is greater than 297 °C, and it has a spatial network structure in aqueous solution, which exhibits strong clay-particle adsorption and suspension stability. After aging at 180 °C for 16 h, the apparent viscosity of the drilling fluid containing 2 wt% P-DADL is 62 mPa·s, the viscosity retention rate is 70.86%, and the FL API is only 7.4 mL. Under the conditions of 180 °C and 35 wt% NaCl, the FL API was further reduced to 6.4 mL, reflecting the salt synergistic filtration reduction characteristics. In addition, the suspension stability of saturated brine drilling fluid is greater than 98% within 48 h. P-DADL can effectively enhance the temperature resistance and salt resistance of water-based drilling fluid. Compared with commercial products, P-DADL exhibited a 78.4% improvement in filtration performance relative to commercial products. These findings highlight the potential of P-DADL as a multifunctional additive for high-salinity, high-temperature drilling operations.

Carbonyl iron powder (CIP) exhibits excellent performance in absorbing waves, but the high thermal conductivity limits its engineering applications in safe thermal protection. This study proposes an integrated material design strategy based on interface engineering. Hollow glass microspheres (HGMs) and CIP are chemically coupled to create a micro-resonator network with thermal insulation properties. The effects of functional filler on thermal insulating and microwave absorption properties were systematically studied. The results show that the composite material demonstrates excellent microwave absorption performance, with a reflection loss (RL) of -33.96 dB at an addition of 30%. When the addition is increased to 40%, the microwave absorption performance of composite material decreased. However, the thermal conductivity is only 0.12128 W/(m·K) and the composite material shows excellent flame retardancy due to the structural characteristics of HGMs. The efficient integration of heat insulation and wave absorption performance was successfully realized through an ingenious interface structure design.

In the face of increasingly complex electromagnetic (EM) pollution, heterogeneous interface engineering is an effective strategy to promote EM response. The enrichment of heterogeneous interfaces can be achieved by constructing hierarchical hollow structures. In this study, waxberry-like hierarchical hollow carbon nanospheres (HHMC) embedded with ultrafine Mo 2 C nanoparticles (NPs) are synthesized by carbonization of phenolic resin microspheres using ammonium molybdate as a molybdenum source and SiO 2 as a pore-forming agent. Among them, the good dispersion of Mo 2 C NPs forms a large number of nanoscale heterogeneous interfaces, which strengthens the polarization relaxation process. Concurrently, the hierarchical hollow structure optimizes the impedance matching with the air medium. Thanks to these properties, the prepared HHMCs exhibit remarkable EM attenuation capacity with a minimum reflection loss (RL) of -59.6 dB and an effective absorption bandwidth (EAB) up to 4.8 GHz. Furthermore, macroscopic three-dimensional (3D) metasurface simulations reveal its ultra-broadband absorption characteristics, which extend from 10.4 GHz (7.6-18 GHz) to 14.1 GHz (3.9-18 GHz) as the thickness increases from 1.4 mm to 3 mm. This result provides fundamental guidance for efficient EM energy attenuation through heterogeneous interface engineering.

Designing composite structures with simultaneous fire and smoke suppression remains challenging due to the stage-dependent pyrolysis behaviors of polymer composites during combustion. Herein, a ferrocene@cucurbituril[n] (Fc@(CB) n ) host–guest system was fabricated via a simple, green, and spontaneous self-assembly strategy and incorporated into epoxy resin as an efficient additive. With only 2 wt% Fc@(CB) n , the limiting oxygen index of the epoxy increased significantly from 23.0% to 27.5%, while the peak heat release rate, total heat release, total smoke release, and CO/CO 2 ratio were reduced by 16%, 29%, 26%, and 26%, respectively. Mechanistic investigations revealed a hierarchical combustion-catalysis behavior across different fire stages. In the gas phase at lower temperatures, iron- and aromatic-derived radicals efficiently scavenged high-energy H· and OH· radicals, suppressing flame propagation. At elevated temperatures, cucurbituril cavities adsorbed small-molecule pyrolysis gases, while ferrocene generated active iron radicals that catalyzed smoke suppression. Notably, in the condensed phase, a continuous and thermally stable char layer composed of (CB) n and Fc@(CB) n was formed for the first time, acting synergistically as a carbonization catalyst and phase-transfer medium to effectively block heat, oxygen, and mass transfer. This work elucidates a multilevel flame-retardant and smoke-suppressive mechanism enabled by host–guest chemistry and provides a novel strategy for developing high-performance fire-safe epoxy composites for architectural, transportation, and electronic applications.

The widespread adoption of bio-based polyurethanes is frequently hampered by the inherent trade-off among mechanical strength, thermal stability, and environmental durability, a common challenge in sustainable polymer design. To address this fundamental challenge, a synergistic molecular design of the key polymer constituents was innovatively implemented in this study. A simultaneous enhancement of all three properties was achieved through the concurrent incorporation of the rigid ring structure of isosorbide (ISO) and the inorganic Si–O framework from (3-aminopropyl) triethoxysilane (APTES) into a castor oil-based polyurethane network. The synergistically modified polymer exhibits a tensile strength of 26.87 MPa, an increased thermal decomposition temperature reaching up to 324 °C, and a distinctly altered degradation profile. Molecular simulations revealed the three-tier mechanisms of this biobased polyurethane material: (1) the rigid ISO skeleton promotes ordered packing and bond localization; (2) the APTES constructs a Si–O network that provides a thermally stable backbone; (3) the dynamic hydrogen-bonding network facilitates excellent energy dissipation. This work successfully circumvents the performance trade-off prevalent in polymer materials through synergistic molecular design, providing a novel design strategy and critical insights for the fabrication of high-performance bio-based polyurethanes. The proposed synergistic enhancement approach pioneers a new technical pathway for the design of high-performance polymers.

Electrocatalytic CO 2 reduction to multi‑carbon products offers a sustainable route to fuels and chemicals, yet suffers from sluggish C C coupling and competing hydrogen evolution. Here, we report a rationally engineered Cu 3 N/Cu@C heterostructure catalyst that delivers markedly enhanced CO 2 electroreduction performance. The optimized catalyst achieves a 65.3% Faradaic efficiency toward multi‑carbon products and a half-cell energy efficiency of 35.3% at −1.1 V versus reversible hydrogen electrode. Combined in situ attenuated total reflectance surface enhanced infrared absorption spectroscopy and density functional theory calculations reveal that interfacial charge transfer at the Cu 3 N/Cu junction modulates the electronic structure of Cu sites, elevates local pH, strengthens CO 2 adsorption and activation, and suppresses hydrogen evolution. Importantly, the tailored interface facilitates asymmetric C C coupling between *CO and *COH intermediates, stabilizing the key *OCCOH species and accelerating multi‑carbon products formation. This work underscores heterointerface engineering as a powerful strategy to control reaction microenvironments and C C coupling pathways, guiding the development of high-performance copper-based CO 2 reduction reaction catalysts.

With the development of industry, large quantities of volatile organic compounds (VOCs) not only cause damage to the ecological environment, but also pose a serious threat to human health. At present, most photocatalysts used for benzene treatment still suffer from problems such as narrow light absorption range, high electron-hole recombination rate, and low charge transfer efficiency. Therefore, the development of high-performance photocatalysts is extremely urgent. The introduction of oxygen vacancies and the construction of heterojunctions can effectively solve the above problems. In this study, a defect-rich photocatalyst was combined with a topology-structured metal-organic framework (MOF) to construct a tightly coupled heterojunction, aiming to address these issues and improve the photocatalytic degradation performance of benzene. By introducing oxygen vacancy-rich TiO₂ nanosheets into NH₂-MIL-125, a tightly coupled Z-scheme heterojunction composite photocatalyst is fabricated. The benzene degradation efficiency of the composite reaches up to 98.5%, which is 1.47 times and 1.27 times that of pure NH₂-MIL-125 and oxygen vacancy-rich TiO₂, respectively, while also exhibiting remarkable stability and high adsorption capacity. Oxygen vacancies act as active sites that strengthen the interfacial electronic interaction of the composite, thereby optimizing the electron transport pathway of the heterojunction and improving the carrier separation efficiency. Under the dual modulation of the heterojunction and oxygen vacancies, the built-in electric field is further intensified, leading to a significant enhancement in the adsorption and catalytic performance of the composite. This study provides an effective design strategy for utilizing oxygen vacancy-driven heterojunctions in catalysts for the efficient abatement of VOCs.

Accurate monitoring of blood glucose concentration is crucial for diabetes diagnosis. In this work, a three-dimensional hierarchical structure was fabricated by incorporating CoCu-layered double hydroxide onto flexible carbon foam (CoCu-LDH/FCF). Its porous, sponge-like architecture provides a high specific surface area and exposes abundant catalytic sites, thereby enhancing electrocatalytic performance for glucose sensing. The CoCu-LDH/FCF composite was immobilized onto a screen-printed electrode (SPE) to construct a portable sensor, designated as CoCu-LDH/FCF/SPE. The resulting sensor exhibits excellent electrocatalytic activity toward glucose oxidation, featuring a linear detection range of 2–500 μM, a sensitivity of 25.6 μA·μM −1 ·cm −2 , favorable selectivity, and long-term stability. Furthermore, a portable detection platform was developed by integrating the sensor with a flexible electrochemical integration module and a smartphone. Experimental results demonstrate the high performance of the CoCu-LDH/FCF/SPE sensor within this compact system.

Triethylamine, a typical volatile marker gas produced during food spoilage, serves as a key indicator of food freshness. Therefore, real-time monitoring of its concentration is of great significance for evaluating food freshness. We synthesize the NiCo 2 O 4 /ZnO using hydrothermal method for triethylamine detection. To characterize the as-prepared samples, XRD, XPS, SEM, XPS, and EIS are used. Among the pure NiCo 2 O 4 , ZnO, and NiCo 2 O 4 /ZnO, the NiCo 2 O 4 /ZnO exhibits (50.2) toward 30 ppm triethylamine, which is around six times higher than that of pure NiCo 2 O 4 at 250 °C. Furthermore, the NiCo 2 O 4 /ZnO composite exhibits rapid response-recovery kinetics, excellent humidity stability, and a favorable selectivity toward triethylamine. The enhanced gas-sensing performance can be attributed to the increased specific surface area, the formation of p–n heterojunctions, and the synergistic interaction between NiCo 2 O 4 and ZnO. These results indicate that the integration of NiCo 2 O 4 with ZnO to create NiCo 2 O 4 /ZnO emerges as an effective approach to enhance the sensing performance of triethylamine.

Layered sodium trititanate (Na2Ti3O7, NTO) is one of the most promising anodes for sodiumion battery (NIBs) owning to its merits of low charge potential and cost-effectiveness. However, it suffers from undesired interfacial reaction, sluggish Na+ transport kinetics and structural instability against cycling. Herein, a fluorinated surface-to-bulk modification strategy is applied to NTO, enabling surface NaF-coating and bulk F-doping, to enhance its rate capability and cycling stability. Experimental and computational calculation results demonstrate that F-doping lowers the bandgap energy of NTO and introducing the strengthen Ti-F bonds, facilitating electron transfer and enhancing the structural stability against cycling. Meanwhile, the NaF-coating minimizes electrolyte decomposition and facilitates the construction of NaF-enriched SEI, which is beneficial for Na+ diffusion. As a result, the fluorinated electrode (F-NTO) exhibits a reversible Na+ storage specific capacity of 172 mAh g-1 at 0.1C and a high-rate capability of 104 mAh g-1 at 5C. In addition, the F-NTO electrode delivers a long cycling life with 78.8% capacity retention after 2000 cycles at 1C, far outperforming the unmodified NTO electrode. This surface-to-bulk synergistic modification provides a robust approach to constructing high-performance titanate anode materials for developing super-charging and long-life NIBs.

With the ever-growing research intereset in hydrogen storage materials, rationally designing suitable catalysts for ammonia borane (AB) hydrolysis and clarifying the catalytic mechanism remain essential and challenging. Herein, Ru, Pt and Pd were supported on the carriers with varying N contents via impregnation reduction with NaBH4. Kinetc isotope effect studies and a series of characterization methods were applied to explore the dehydrogenation mechanism, revealing that the cleavage of O-H in water is the rate-determining step (RDS) of the reaction. Owing to their electronic and anchoring effects, Ru-based catalysts exhibit high catalytic activity in AB dehydrogenation. Specifically, the optimal Ru/ZrN with an average particle size of 1.4 nm exhibits remarkable hydrogen evolution activity and turnover frequency (TOF=305.3 min-1) under ambient conditions, superior to the corresponding monometallic counterparts (i.e., Pd/ZrN and Pt/ZrN) and many previous reports. Apart from satisfactory durability, the optimal catalyst exhibits a remarkably low apparent activation energy (31.48 kJ/mol). This work elucidates how support nitrogen contents modulate the metal-support electronic interaction, thereby providing a strategy for designing high-performance catalysts and filling a knowledge gap in AB dehydrogenation mechanisms.
