Gel polymer electrolytes hold significant promise for next-generation solid-state sodium metal batteries (SMBs) due to their high ionic conductivity and favorable interfacial contact with electrodes. However, their practical application is limited by inherent flammability, inferior mechanical properties, and poor interfacial compatibility with sodium metal anodes. Herein, we introduce a rationally designed covalently crosslinked nanoconfinement strategy to in situ build a mechanically robust asymmetric flame-retardant composite gel electrolyte (AFCGE) to achieve highly stable SMBs, where a chemically crosslinked covalent organic framework (COF) network is constructed on a glass fiber matrix along with synchronously polymerized flame-retardant polymers. The in situ formed COF network provides innate nanochannels that spatially confine polymer growth, which not only enhances mechanical robustness but also significantly promotes local Na + transport kinetics and facilitates uniform sodium deposition at the anode side, thereby effectively suppressing dendrite growth. Thus, the AFCGE exhibits high ionic conductivity, excellent mechanical properties, superior flame retardancy, and outstanding interfacial stability. Na/Na symmetric cell achieves an ultralong cycling lifespan exceeding 4000 h with low polarization at 0.1 mA cm −2 . Quasi-Solid-state SMBs further demonstrate excellent electrochemical performance, and no thermal runaway or electrolyte leakage occurs in pouch cells, underscoring their potential for safe and durable energy storage.

CA-125, as a tumor marker for ovarian cancer, plays an importance role for rapid and sensitive detection in early diagnosis. Herein, a label-free electrochemical immunosensor based on COF/PTh/MB nanocomposite was constructed for the detection of CA-125.The TAPB-DMTP-COF material, with its large surface area and stable porous framework, was used as the substrate. However, its poor conductivity hindered electron transfer. To address this, conductive polymer PTh was combined with the COF to enhance the composite's conductivity. Meanwhile, MB was used as a signal probe, and differential pulse voltammetry (DPV) was adopted to measure the electrochemical signal. Under optimized experimental conditions, the proposed immunosensor exhibited excellent performance for the CA-125 detection, with a detection range of 1 mU/mL-10000 mU/mL, and a low detection limit of 0.34 mU/mL (S/N = 3), providing a potential platform for clinical application.

Covalent organic frameworks with three-dimensional networks and interconnected porous structures show promising advantages for hydrogen peroxide photocatalysis. However, 3D COFs are typically constructed from 3D-oriented knots with less conjugation and insufficient light absorption, which significantly inhibits their performance. Herein, we present a universal defect engineering approach by systematically replacing T d knots with trigonal planar ligands and modifying linear linkers with electron-withdrawing/donating groups to achieve simultaneous enhancement of light absorption and precise electronic tuning of 3D donor-acceptor structures. Experimental results and theoretical analysis reveal that the optimized 3D COF with planar ligands induced defects and fluorine functional groups (COF-300-D-F), which achieve an H 2 O 2 production rate of 19.09 mmol g −1 h −1 and apparent quantum yield of 11.95% at 400 nm with benzyl alcohol as sacrificial agent. Moreover, the material maintains long-term stability during continuous operation exceeding 96 hours and exhibits high activity in photocatalytic benzylamine coupling reactions.

In this study, an injectable conductive hydrogel (MeGG/PN@PP@G-8) based on a gellan gum/chitosan dual network (MeGG/PN) was designed and constructed. PEDOT: PSS imparts electrical coupling to the material, while the G-8 small molecule provides anti-inflammatory and anti-fibrotic activity. This system reduced ROS levels by 93.7% under H₂O₂-induced oxidative stress and increased the proportion of RAW264.7 macrophages toward the M2 phenotype by threefold, thereby shaping an immune microenvironment conducive to repair. In a rat myocardial infarction model, MeGG/PN@PP@G-8 patch treatment reduced IL-1β, IL-6, and TNF-α expressions by 96.1%, 95.3%, and 94.9%, respectively, nearly returning to sham group levels. Furthermore, treatment with the hydrogel reduced fibrosis area and enhanced angiogenesis and sarcomere remodeling. Transcriptome analysis further revealed that the material simultaneously inhibits pro-pathogenic pathways such as NF-κB/TNF and TGF-β/SMAD, while activating PI3K-Akt, ECM receptors, and angiogenic genes, achieving multi-pathway synergistic effects of anti-inflammatory, anti-fibrotic, pro-regenerative, and electrophysiological repair. The “wet adhesion-electrical coupling-drug synergy” strategy proposed in this study provides an innovative material platform and mechanistic basis for tissue regeneration and functional recovery after myocardial infarction.

To meet the demand for lightweight, high-performance and green sustainable materials, basalt fiber-reinforced polyamide 66 (BF/PA66) composites show great application potential in aerospace and automobile manufacturing. However, poor interfacial compatibility between basalt fibers (BF) and PA66 matrix limits their comprehensive performance. In this study, BF surfaces were modified with amino (KH-550), epoxy (KH-560) and mercapto (KH-590) silane coupling agents to enhance interfacial bonding. Systematic tests were conducted on composites with 15 wt% fiber content. The results showed that all silane coupling agents were successfully grafted onto BF surfaces via Si-O-Si covalent bonds, improving fiber surface roughness and reactivity. KH-550 modification achieved the optimal performance: tensile, flexural and impact strengths increased by 25.12%, 45.57% and 46.08% respectively compared with pure PA66, with the strongest interfacial binding energy (−7.84 kcal/mol). Additionally, KH-550 reduced water absorption by 38.89% and improved thermal stability. This study provides an efficient and eco-friendly method for interfacial regulation of BF/PA66 composites.

Glyphosate is a persistent herbicide that contaminates water and poses health risks, yet conventional removal methods remain limited. Photocatalysis offers a promising alternative but is hindered by issues such as charge recombination, poor light utilization, and the formation of phosphate (PO 4 3- ) by-products. In this study, a coupled system is constructed, comprising ZnIn 2 S 4 nanocage (ZIS-HNCs)/BiOCl mesoporous single-crystal nanosheet (BiOCl MSCN) heterojunction–photocatalytic optical and Fe-modified zeolite fibers, to completely remove glyphosate from aqueous environments. Light radiated from the hollow optical fibers excites the ZIS-HNCs/BiOCl MSCN photocatalyst to generate electron–hole pairs. The formation of a heterojunction between ZIS-HNCs and BiOCl MSCN accelerates interfacial charge transfer, increases the production of holes and electrons, and consequently enhances their performance in degrading glyphosate. PO 4 3- produced from photocatalytic degradation is removed in situ by the Fe-modified zeolite fibers through Fe–O–P coordination and electrostatic adsorption. This suppresses the quenching of photogenerated electron–hole pairs by PO 4 3- , further enhancing the efficiency of glyphosate degradation and inhibiting the formation of phosphate by-products. The photocatalysis–ion adsorption coupling strategy provides a novel and effective approach for the simultaneous removal of pesticide residues from aquatic environments.

This work simplified the structure of waste iron-containing sludge from groundwater treatment plants to explore its mechanism of activating periodate(PI) for degrading organic pollutants in water. The pH during preparation was used to regulate the crystallinity and the doping of transition metal Mn in the precursor solution to prepare catalysts similar to the waste iron-containing sludge. Sulfadiazine (SDZ) was selected as the model contaminant, and it was found that the efficiency of the prepared catalyst to remove the contaminants was 100% in 10min by activating PI. Combining electrochemical and performance experiment results, it was found that the amorphous part of the material can optimize the electronic structure and enhance the electron transfer ability. However, Mn doping can also reduce the electron transfer resistance, and the synergistic effect of Fe-Mn bimetal occupied a more important part in the entire catalytic system. According to the results of Electron paramagnetic resonance (EPR) and quenching experiments, it was found that although a variety of free radicals were produced, the active substances that contributed the most were IO 3 • and 1 O 2 . The materials showed certain environmental adaptability in the subsequent experiments. This study provides theoretical support for removing organic pollutants from waste iron-containing sludge and provides some basic insights for bimetal synergistic activation of PI.

Global arable land is shrinking. Public health burdens from metabolic and intestinal disorders are rising. Developing functional cereal crops for marginal lands is now a critical research priority. This study investigated a novel resistant starch (RS)-enriched Seawater Rice (SR). We compared its benefits to Waxy Rice (WR) and Normal Rice (NR). SR had the highest RS content and WR was dominated by rapidly digestible starch. In an oral glucose tolerance test, SR uniquely reduced acute postprandial glycemic spikes. In vitro fermentation showed SR distinctly altered gut microbiota. SR downregulated pathogenic Escherichia-Shigella and enriched beneficial Bifidobacterium and Ligilactobacillus . In Dextran sodium sulfate (DSS)-induced colitis mouse model, SR alleviated body weight loss and enhanced intestinal barrier function. It also restored key short-chain fatty acids (SCFAs) levels. WR and NR showed no protective effects. These findings highlight SR’s RS-driven superiority via the gut microbiota-SCFA axis, supporting its potential as a functional food for glycemic control and colitis prevention.

Mini/Micro-LED backlight systems require color conversion layers that combine submicron size with high absorption efficiency. However, commercial phosphors are difficult to meet this demand due to their relatively large particle size. The Cs 2 MnF 6 system demonstrates a unique advantage due to its intrinsic high absorption efficiency. In this study, submicron-sized Cs 2 MnF 6 was successfully prepared via anti-solvent synthesis method. Furthermore, a Si 4+ reverse doping strategy was employed (Cs 2 MnF 6 :Si 4+ ) to effectively suppress concentration quenching. At the optimal doping concentration, the emission intensity reaches 3523 times that of the undoped Cs 2 MnF 6 host. Subsequently, surface passivation treatment was applied with a Mn 4+ -free Cs 2 SiF 6 coating. This treatment not only suppressed surface quenching, further increasing the luminescence intensity, but also significantly improved the material's moisture resistance. The finally obtained Cs 2 MnF 6 :Si 4+ @Cs 2 SiF 6 phosphor has an average particle size of approximately 800-900 nm and a high absorption efficiency of 48.4%. Its luminescence intensity is 4.25 times that of the un-passivated sample. And this material retained 75% of its initial luminescence intensity after 240 minutes of immersion in deionized water. In contrast, the untreated sample remained only 16.4%. These advancements highlight the significant potential of this material in mini/micro-LED backlight systems, offering new possibilities for the development of next-generation display technologies.

Endocrine-disrupting bisphenols as endocrine disrupting chemicals present significant risks to the human endocrine system. Developing accurate and highly sensitive methods for detecting trace levels of bisphenols in food is crucial to ensure food safety and prevent health risks. Herein, a hydroxyl-functionalized covalent organic framework (TD-COF) was synthesized using 4,4′,4′'-triaminotriphenylmethane and 3,3′-dihydroxy-[1,1′-biphenyl]-4,4′-dicarbaldehyde as monomer. TD-COF demonstrates superior adsorption ability for bisphenols compared with hydroxyl-free COF, which can be primarily attributed to the presence of hydrogen bonding and π-π interactions. By combining high performance liquid chromatography-mass spectrometry and solid phase extraction technology based on TD-COF, a method for analyzing four bisphenols in river water and chicken was established. Under optimal conditions, the method exhibits a low detection limit (river water: 0.03-0.15 ng mL -1 , chicken: 1.4-3.5 ng g -1 ), satisfactory spiked recovery (river water: 87.0-107%, chicken: 88.5-105 %) and good relative standard deviations (river water: 4.5-6.5%, chicken: 4.0-5.7%).

Epoxy resin-hollow glass microsphere composites (EHC) exhibit low density and excellent mechanical properties, making them promising candidates for marine/aerospace applications. However, their high flammability severely restricts broader use. To improve flame retardancy while maintaining low density, ammonium polyphosphate-coated hollow glass microspheres (APP-HGM) were utilized to fabricate flame-retardant epoxy composites (EAHC). EAHC achieved improved flame retardancy and maintained low density, but it suffered from insufficient flame-retardant efficiency and notable mechanical degradation. To address these drawbacks, SmMn 2 O 5 mullite nanoparticles (SMO) were further incorporated to fabricate the multi-component flame-retardant epoxy composite (SMO-EAHC). Systematic characterizations including thermogravimetric analysis (TG), limiting oxygen index (LOI), vertical burning (UL-94) and cone calorimeter test confirmed that APP-HGM serves as both a flame-retardant filler and a lightweight matrix component, while SMO catalyzes the decomposition of APP and promotes the formation of compact char layers. SMO-EAHC achieved a LOI of 27.6% and a UL-94 V-1 rating, and presented remarkable reductions of 58.81%, 38.67%, 73.65% and 62.96% in peak heat release rate (pHRR), total heat release (THR), peak smoke production rate (pSPR) and total smoke production (TSP) compared with unmodified EHC. Meanwhile, SMO-EAHC exhibited a compressive strength of 23.84 MPa, representing a 32.08% improvement relative to EAHC, while maintaining a low density of 0.66 g/cm³ . In summary, this work proposes a targeted two-step modification strategy, involving APP-HGM functionalization followed by SMO complementation, to address the flammability of EHC. This strategy realizes the balanced integration of flame retardancy, lightweight characteristic and pressure resistance, providing technical support for the application of polymer composites in extreme environments.

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.
