The sensitive detection of trace endocrine disruptors holds immense practical significance for safeguarding food safety. Herein, a boronic acid-decorated magnetic porous organic polymer (POP-PA@Fe 3 O 4 ) was synthesized as adsorbent for the extraction and enrichment of several phenolic endocrine disruptors (PEDs). The decoration of boronic acid provides a high density of hydroxyl groups, significantly enhancing its adsorption performance. POP-PA@Fe 3 O 4 exhibited excellent adsorption capability toward PEDs by virtue of H-bonding interactions and π-π stacking. Subsequently, combined with high-performance liquid chromatography/mass spectrometry (HPLC/MS), a sensitive method for the determination of PEDs in milk was established by employing POP-PA@Fe 3 O 4 as a magnetic extraction adsorbent. The method showed low detection limits (S/ N = 3) of 0.080–0.40 ng·mL −1 . The recoveries of spiked samples spanned 84.6% to 100.0% with RSD ≤ 7.5%. This work presents a feasible approach for the detection of PEDs in milk and further expands the application of functionalized porous organic polymers in food safety monitoring.

In this study, we developed catechol-imprinted magnetic molecularly imprinted polymers (Ca-DFFPBA-MMIPs) via a dual-affinity strategy combining boronate affinity and a two-step template immobilization protocol. The Ca-DFFPBA-MMIPs exhibited high affinity and selectivity for catecholamines (norepinephrine, epinephrine, and dopamine) under neutral conditions. The adsorption capacity reached a plateau at pH 6.5–7.0, and the adsorption time was optimized to 40 minutes. The MMIPs showed excellent selectivity for the target catecholamines over structurally related interferents. The Ca-DFFPBA-MMIPs also demonstrated good reusability, retaining ≥90% of their initial adsorption capacity after seven consecutive cycles. The analytical performance of the Ca-DFFPBA-MMIPs was validated in terms of linear range, coefficient of determination (R²), limit of detection (LOD), limit of quantification (LOQ), and intra- and inter-day precision (RSD). The LODs were 12–31 ng mL⁻¹ and LOQs were 40–103 ng mL⁻¹, with RSDs of 0.87–1.13% (intra-day) and 1.75–1.95% (inter-day). The Ca-DFFPBA-MMIPs were successfully applied to the selective extraction of catecholamines from equine urine (enrichment factors of 18–27), with recoveries ranging from 64.5% to 105.7%. This study provides a new approach for the analysis of catecholamines in complex matrices and highlights the potential of Ca-DFFPBA-MMIPs as a practical nanosorbent for efficient and selective enrichment of catecholamines and related compounds.

Developing bifunctional oxygen electrocatalysts with excellent activity and durability is critical for scaling rechargeable zinc–air batteries (ZABs). Herein, we propose an integrated “etching–doping–phosphorization/carbonization” route to synthesize Ni 2 P/Co 2 P heterojunctions anchored on B,N,P co-doped carbon (Ni 2 P/Co 2 P-NPBC). Firstly, boric acid etching of the ZIF(Zn, Co, Ni) generates a bird-nest-like porous framework and simultaneously introduces boron; subsequent phosphorization/carbonization at 1000 °C yields Ni 2 P/Co 2 P nanocrystals uniformly anchored on the B, N, P co-doped carbon. It is confirmed that the carbon framework exhibits abundant defects and contains B, N, and P atoms chemically bonded to the matrix. This structure possesses a high surface area and a through-pore network, which ensure the exposure of active sites and facilitate rapid mass transport. Density functional theory (DFT) calculations show that boron doping markedly decreases charge density and upshifts the d-band center of Co sites in the Ni 2 P/Co 2 P heterojunction (from −1.26 to −0.87 eV), thereby raising the oxygen reduction reaction (ORR) limiting potential (from 0.34 to 0.69 V) and lowering the oxygen evolution reaction (OER) theoretical overpotential (from 0.89 to 0.54 V). Benefiting from these features, Ni 2 P/Co 2 P-NPBC in alkaline media delivers an ORR half-wave potential of 0.88 V (vs. 0.85 V for 20% Pt/C) and an OER overpotential of 264 mV at 10 mA cm −2 (vs. 308 mV for RuO 2 ). A lab-fabricated ZAB achieves an open-circuit voltage of 1.586 V, a peak power density of 180.8 mW cm −2 , a specific capacity of 816.2 mAh g −1 , an energy density of 1159.0 Wh kg Zn −1 , and 600 h stable cycling.

Biofuel is a promising solution for energy crisis and excessive CO 2 emission. Membrane-based pervaporation process enhances biomass fermentation by constantly separating inhibitory bio-alcohols. However, dominating pervaporation membranes often show low permeation flux and inadequate separation factor. Herein we report the engineering fabrication of flexible composite hollow fiber membranes (HFMs) with oriented metal-organic framework (MOF@ZnO) arrays for ethanol-water separation. The epitaxial MOF arrays containing one-dimensional (1D) transport channels was constructed on HFMs, followed by a superhydrophobic and defect-free surface coating. The arrayed structure induces the flow pattern enhancement near the feed-membrane interface and increases mass transfer area, resulting in self-enhancing separation performance. The synergistic effects of the arrayed surface structure and MOF transport channels on separation performance enhancement were revealed by the experimental and simulation results. Impressively, for the composite HFM, the activation energy of ethanol was found to be lower than that of water. When applied to the pervaporation of a 5 wt% ethanol-water mixture, this membrane achieved an ultrahigh flux along with a good separation factor of 10.5. The versatile strategy is suitable for both inner- and outer-selective HFM modules as well as for various membrane materials which exhibit great potential for industrial applications.

Photo-assisted rechargeable batteries exhibit excellent electrochemical performance, attributed to their unique photoenhancement effect. However, their performance is constrained by low utilization efficiency of photogenerated carriers in the cathode material. We herein realize the targeted modulation of photogenerated electron selectivity with the aim of maximizing the lithium storage capacity per unit time by constructing a metal–organic coordination system. This system integrates magnetic cobalt (Co) centers, 2,2′-bipyridine photoactive units, and two specific storage ligands (i.e., DHBQ and BQ). Upon photoexcitation, the strong ligand-to-ligand charge transfer (LLCT) effect facilitates electron transfer between different lithium-storage ligands. Furthermore, the application of an external magnetic field extends the photogenerated carrier lifetime and improves separation efficiency by modulating spin-polarized carriers and enhancing spin–orbit coupling, which further enhances LLCT. Benefiting from the combined modulation of illumination and magnetic field, the organic cathode delivers a discharge capacity of 416 mAh g −1 . This work not only provides new insights into the dynamics of photogenerated carriers in battery cathodes but also offers valuable guidance for the development of multi-field regulated energy storage systems.

Covalent organic frameworks (COFs) with long-range ordered periodic structures have emerged as promising photocatalysts for advanced oxidation processes. Herein, we reported a highly crystalline porphyrin-based COF (COF-TAP-Cu) featuring outstanding visible-light-driven oxidation activity. COF-TAP-Cu was obtained via a facile bottom-up metallization strategy that tuned the conjugation and planarity of the porphyrin building block (TAP-H). Incorporation of Ni 2+ or Cu 2+ into TAP-H moderately enhanced the π-conjugation of the resulting metalloporphyrin monomers (TAP-M; M = Ni, Cu), leading to markedly improved crystallinity of the corresponding COFs. Notably, structural analysis indicated that the porphyrin ring in TAP-Ni undergoes pronounced distortion, whereas TAP-Cu retained a near-planar geometry. As a result, COF-TAP-Cu exhibited higher crystallinity and superior photocatalytic oxidation performance compared with the metal-free porphyrin-based COFs (COF-TAP-H) and Ni-anchored porphyrin-based COFs (COF-TAP-Ni). Under visible-light irradiation, COF-TAP-Cu efficiently activated molecular oxygen to produce both O 2 •- ( via electron transfer) and 1 O 2 ( via energy transfer), enabling rapid degradation of sulfadiazine (SDZ) with a removal efficiency of up to 95% within 30 min. This work highlighted a monomer-design strategy that balanced conjugation and planarity to construct highly crystalline porphyrin-based COFs, offering new insights for photocatalytic antibiotic remediation in aquatic environments.

Alkylphenol ethoxylates (APEOs) in waterborne coatings (WBCs) pose substantial health and environmental risks due to their estrogenic degradation metabolites, necessitating robust analytical methods to meet stringent regulations. Conventional liquid chromatography-mass spectrometry (LC-MS) methods often suffer from congener separation difficulties and severe matrix interference. To overcome these limitations, we developed an analytical procedure based on facile one-pot cleavage technique using aluminum iodine (AlI 3 ) generated in-situ for the reliable quantification of APEOs in WBCs. The method integrates three core innovations: (1) rapid dehydration with MgCl 2 (1.5 × the mass of sample water) to prevent moisture-induced AlI 3 decomposition; (2) efficient, one-pot AlI 3 -mediated cleavage under ultrasonic irradiation (85 °C, 20 min) for quantitative APEOs-to-alkylphenol (AP) conversion; and (3) simple, quantitative AP isolation via tert -butyl methyl ether (BME) extraction. Validated using gas chromatography-mass spectrometry (GC-MS), the method exhibited excellent linearity (R 2 > 0.999), low limits of quantification (3.0 mg/kg for OPEO 10 , 9.0 mg/kg for NPEO 10 ), satisfactory recoveries (92.9–107.4%) and relative standard deviations (RSDs) ≤ 11.8%. Compared to routine LC-MS methods, this approach effectively mitigates matrix effects, reduces analytical cost, and offers a greener alternative suitable for batch analysis. Application to 20 real WBC samples confirmed its reliability in quantifying APEOs across concentration ranges, from low-level contaminants to high-load formulations. Overall, this integrated strategy enables sensitive, rapid and accurate APEO analysis, presenting a promising new avenue for screening these contaminants in complex sample matrices such as WBCs.

Nickel–Titanium (NiTi) biliary stents are widely used to treat stenosis and obstruction but are susceptible to biofilm formation and bile sludge accumulation, leading to stent fouling and failure. To address this, we developed a novel anti-fouling coating for NiTi stents via gas atomization spraying. The coating consists of poly(2-methoxyethyl acrylate) (PMEA) and an incorporated antimicrobial agent, which remains stable within the as-deposited matrix. The drug release kinetics from the composite coating followed the Korsmeyer-Peppas model. Notably, the addition of the antimicrobial agent had negligible impact on the surface microstructure or hydrophilicity of the coating. Its concentration was systematically optimized to balance antimicrobial efficacy with biocompatibility. The coating demonstrated significant antifouling properties in sequential evaluations against protein adsorption, bacterial adhesion, and biliary sludge accumulation. Our findings indicate that this PMEA-based drug coating effectively mitigates fouling and restenosis across multiple key stages. The gas atomization-sprayed PMEA-antimicrobial coating thus presents a promising strategy to suppress biofilm formation, prevent cholestasis, and enhance the long-term patency of biliary stents.

This study investigated the synergistic effect of fat and sarcoplasmic protein on the flavor profile of chicken white soup. The impact of adding 2% fat (2%O), 0.56% sarcoplasmic protein (0.56%P), and their combination (2%O-0.56%P) on volatile compounds, taste components, and sensory characteristics was evaluated. Through odor activity value (OAV) and gas chromatography-olfactometry (GC-O) analysis, hexanal, heptanal, octanal, nonanal, (E,E)-2,4-decadienal, (E)-2-octen-1-al, and 1-octen-3-ol were identified as key aroma contributors. The combination of 2%O and 0.56%P markedly enhanced the aroma profile of the chicken soup, concurrently achieving the highest levels of amino acids and 5′-nucleotides. Furthermore, electronic tongue analysis revealed that the chicken soup supplemented with 2%O-0.56%P exhibited the lowest bitterness value and achieved the highest overall acceptability. These findings demonstrate that the synergistic effect of fat and sarcoplasmic protein effectively improves the flavor quality of chicken white soup, providing a theoretical basis for developing flavorful, tasty, and consumer-preferred chicken soup products.

Stimuli-responsive active corrosion protection coatings serve as both an effective physical barrier and an active corrosion protection system for metallic substrates. However, their long-term performance is typically limited by the irreversible release of inhibitors and a restricted loading capacity, which hinders their repeated active corrosion protection capability and sustained durability. To address these limitations, we have developed a smart dual-stimuli-responsive active corrosion protection coating (denoted as MSNs-BTA@PANI/PVB) by encapsulating benzotriazole (BTA) within mesoporous silica nanocontainers (MSNs) coated with a polyaniline (PANI) shell. PANI, serving as a reversible molecular switch responsive to pH and redox conditions, enables controlled BTA release, ensuring sustained corrosion inhibition and prolonged service life. UV-vis spectroscopy revealed that in 3.5 wt% NaCl solution, minimal surface-adsorbed BTA was released from MSNs-BTA@PANI nanocontainer under pH change, whereas 0.54 mmol L − 1 release was triggered upon N 2 H 4 . After 50 days of immersion, EIS results showed that the coating containing 0.5 wt% MSNs-BTA@PANI achieved a |Z| 0.01Hz value of 1.14 × 10 5 Ω cm 2 , nearly seven times higher than that of the 0.5 wt% MSNs/PVB coating. This enhancement stems from the synergy between the physical barrier effect of MSNs and the dual-stimuli-triggered release of BTA, enabling effective localized corrosion inhibition. This work provides a reversible and controllable active protection strategy based on dual-responsive nanocontainers for designing durable intelligent corrosion protection coatings.

Soft iontronic materials are highly desirable for flexible electronics that operate under deformation and temperature fluctuations, yet practical platforms that combine solid state ionic transport, mechanical robustness, and reprocessability while integrating multiple responsive functions remain limited. Here, a series of X-PEG networks is constructed by integrating acylurea based dynamic covalent linkages, semicrystalline poly(ethylene glycol) segments, and a homogeneously dispersed imidazolium ionic liquid phase. This architecture couples dynamic exchange, associative reinforcement, and reversible crystallinity within one matrix, enabling microstructure governed regulation of mechanics and ion transport. A broad mechanical window is achieved across compositions, with high stretchability and useful strength retained at representative formulations, while ionic conduction is maintained in the 10 −3 to 10 −2 mS·cm −1 range. Robust electromechanical coupling is demonstrated by smooth and repeatable resistance outputs under bending and subtle physiological motions, together with stable cycling performance. Rapid thermal following and heat triggered shape regulation are enabled through PEG crystallization and melting coordinated with relaxation of hydrogen bonded hard domains. Notably, heating produces a resistance decrease that supports temperature triggered circuit warning, consistent with thermally driven microphase reconstruction, primarily through the melting of crystalline domains, which improves the effective connectivity of ion-conducting pathways. The networks are melt-reprocessable, and ionic conductivity as well as strain and temperature responsive sensing outputs are largely preserved after repeated hot pressing cycles. This work establishes a recyclable ionic network platform in which dynamic bonding and semicrystalline switching jointly program microstructure and function, offering a practical materials strategy for sustainable soft iontronic devices.

Resin impregnation is an important wood modification technique. However, conventional thermosetting resins are inherently insoluble and infusible, posing significant challenges to their recycling and reuse-a fundamental contradiction with wood's eco-friendly and renewable nature. This study introduced Schiff base and boronate ester bonds into a water-based epoxy (EP) resin system. The reversible cleavage and rearrangement of these dynamic bonds endowed the EP resin with plasticity, enabling reprocessing and reforming, while enhancing its toughness to overcome the high brittleness of common epoxy resins. The resin formed a stable network within the wood, reducing leaching and improving wood water resistance and dimensional stability. Additionally, silicon in Schiff base moieties and boron in boronate ester groups conferred good flame retardancy to the water-based epoxy resin. For the modified wood: limiting oxygen index (LOI) increased by 28.3%; vertical burning rating reached V-0; infrared thermal imaging central temperature decreased by 61.2%; thickness swelling rate reduced to 2.3%; and elastic modulus significantly increased by 73.33%. Life cycle assessment showed that compared with the PMMA impregnation process, the epoxy resin impregnation process reduced global warming and marine eutrophication impacts by 21.7% and 87.6%, respectively. Accelerated aging tests confirmed that dynamic bonds did not undergo irreversible fracture, and the mechanical properties and water resistance of modified epoxy resin and resin-impregnated wood remained stable. This research provides a novel strategy for strengthening, toughening, flame-retarding, and enabling recyclability of fast-growing wood via dual dynamic bonds in water-based epoxy resin. It addresses thermosetting resin recycling, allows wood reprocessing, extends service life, and expands the application fields of wood-based materials.
