Treating bacteria-contaminated immiscible oily water remains challenging because oil/water separation and antibacterial activity are rarely integrated within one stable interface. Here, we report a polymerizable deep eutectic solvent (PDES)-derived coating that creates a charged ionic hydrated interface on stainless-steel mesh (PAA–ChClM). The PAA–ChClM is superhydrophilic/underwater superoleophobic, showing an underwater oil contact angle of 152° and ultralow oil adhesion. It enables gravity-driven separation of immiscible oil/water mixtures with a high flux of 7.6 × 10 4 L·m −2 ·h −1 and 99.95% separation efficiency, while maintaining performance under acidic, alkaline, saline, and long-term cycling conditions. More importantly, the interface is non-leaching and rapidly kills both Escherichia coli and Staphylococcus aureus within 5 s upon contact. The antibacterial activity originates from direct interaction between the charged ionic hydrated interface and the bacterial envelope, leading to membrane disruption, leakage, and collapse. Multilayer assembly further converts this contact-killing surface into a dynamic filtration platform, achieving near-complete disinfection in flow-through operation and effective treatment of natural lake water. This work establishes a PDES-derived ionic hydrated interface as a practical strategy for unifying anti-oil fouling, oil/water separation, and non-leaching antibacterial activity.

Synergistic reinforcement of self-healing elastomers by strain-induced crystallization and multiple hydrogen bonds. • The elastomer achieves a tensile strength of 52.2 MPa, an elongation at break of 1525.1%, and an toughness of 330.05 MJ/m 3 . • After healing at 60 °C for 24 h, the self-healing efficiencies reached 96.6% for stress and 101.7% for strain. • The fracture energy attained 117.65 kJ m −2 . • The flexible composite sensor exhibits strain-sensing, with GF of 1.71 and 1.87 in the 0–100% and 100–300% strain range. The harsh and complex conditions in practical applications have driven a strong demand for polyurethane (PU) elastomers with self-healing functionality. However, achieving both superior mechanical performance and excellent self-healing ability in a single PU elastomer still poses a significant difficulty. In this investigation, a self-healing PU elastomer (PCL-HMPU) with outstanding mechanical performance was developed. The prepared self-healing PU elastomer demonstrated a superior tensile strength of 52.2 MPa, an elongation at break of 1525%, and an outstanding toughness of 330.05 MJ/m 3 . Specifically, the symmetric Methylene-bis(4-cyclohexylisocyanate) (HMDI) and semi-crystallizable poly(caprolactone) diol (PCL) enable strain-induced crystallization (SIC) under large deformation, thereby providing a self-reinforcement effect. The acylsemicarbazide moieties (ASCZ) and disulfide bonds in 3,3′-dithiobis(propionohydrazide) (DPH) impart the self-healing capability, enabling the elastomer to recover 96.6% of its tensile strength and 101.7% of its tensile strain after 24 h at 60 °C. The amorphous structure of PCL-HMPU facilitates self-healing, while the SIC and ASCZ collaboratively enhances its mechanical performance. Moreover, based on the favorable compatibility between PCL and the ionic liquid, a high-performance ionic skin was fabricated, further highlighting the potential of PCL-HMPU for flexible electronics.

Ammonia synthesis via photocatalytic nitrogen fixation is regarded as a green and sustainable alternative to the conventional Haber-Bosch process. Nevertheless, its practical application is greatly hindered by the chemically inert N N triple bonds and slow reaction kinetics. In this work, a Cu-doped TiO 2 /g-C 3 N 4 composite with a well-defined type-II heterojunction was synthesized through a facile wet-chemical method integrating low-temperature crystallization and in-situ molecular assembly. Characterizations confirm that Cu-TiO 2 nanoparticles are evenly immobilized on g-C 3 N 4 nanosheets, which effectively suppresses nanoparticle aggregation. On the one hand, Cu doping tunes the band structure of TiO 2 and introduces abundant oxygen vacancies, greatly promoting the adsorption and activation of N 2 molecules. On the other hand, the formed type-II heterojunction establishes an internal electric field, which broadens light response and accelerates the separation and migration of photogenerated charge carriers. Benefiting from the synergistic effect of Cu doping, oxygen vacancies and type-II heterojunction, the optimal Cu-TiO 2 /g-C 3 N 4 (CuTCN-2) achieves an outstanding NH 3 evolution rate of 91.14 μmol·g −1 ·h −1 with a quantum yield of 1.75% at 420 nm under simulated solar illumination. The activity is 7.6-, 3.4- and 34.1-fold higher than that of bare TiO 2 , single Cu-TiO 2 and pristine g-C 3 N 4 , respectively. This work reveals that the co-regulation of heteroatom doping, defect engineering and heterojunction construction can remarkably boost photocatalytic kinetics. It also provides a feasible design principle for high-performance photocatalysts toward solar-driven nitrogen fixation.

2D nanocontainers are prepared with barrier, corrosion inhibition and monitoring. • BZ-P/EP coating shows higher .|Z| f = 0.01 Hz of 4.1 × 10 10 Ω cm 2 after 60 days immersion. • PH-responsive ZIF-8 enables the rapid release of Phen under acidic conditions. • Visual corrosion warning is achieved via Fe 2+ –Phen coordination. To overcome the limitations of conventional anticorrosion coatings, which typically exhibit single functionality and lack early-stage corrosion warning capability, this study presents the design and fabrication of a two-dimensional intelligent nanocontainer system. Specifically, a pH-responsive zeolitic imidazolate framework (ZIF-8) was grown in situ on hexagonal boron nitride (h-BN) nanosheets, and subsequently loaded with 1,10-phenanthroline (Phen), enabling the integration of physical barrier protection, active corrosion inhibition, and visual corrosion monitoring. UV–vis absorption spectra and electrochemical impedance spectroscopy (EIS) results demonstrate that the BZ-P nanocontainers not only provide effective corrosion inhibition but also exhibit rapid, pH-triggered release of Phen in mildly acidic conditions. After incorporation into an epoxy matrix, the resulting BZ-P/EP composite coating exhibits a high low-frequency impedance modulus (|Z| f = 0.01 Hz ) of 4.1 × 10 10 Ω cm 2 after 60 days of immersion in 3.5 wt% NaCl solution, which is approximately 2270 times higher than that of the neat epoxy coating. This improvement is accompanied by a significant reduction in oxygen content on the underlying steel surface (from 19.56 wt% to 0.62 wt%), indicating markedly suppressed corrosion. Under damaged coating conditions, the BZ-P/EP system maintains effective corrosion protection, as evidenced by a relatively high impedance modulus and low local admittance. This enhanced performance can be attributed to the synergistic effects of BN and ZIF-8, which combines structural barrier reinforcement with active corrosion inhibition. Furthermore, the released Phen molecules at damaged sites coordinate with Fe 2+ ions to form a red complex, enabling rapid and intuitive visual detection of corrosion initiation. This work provides a novel strategy for developing intelligent coating systems that integrate corrosion protection, active corrosion inhibition, and real-time monitoring, offering significant potential for applications in harsh service environments.

Novel Yb-BiOI/Ce-MgAl-LDH S-scheme heterojunction boosts photo-Fenton degradation. • Substrate molecular orbitals govern the selective 1 O 2 -dominated degradation. • S-scheme heterojunction achieves 100% TC-HCl degradation within 20 min. • The system demonstrates excellent environmental adaptability and stability. • Photocatalytic mechanism elucidated via experiments and DFT calculations. Developing highly selective catalytic systems remains a grand challenge in advanced water remediation. A novel S-scheme Yb-BiOI/Ce-MgAl-LDH heterojunction was rationally designed to synergistically boost photo-Fenton degradation via targeted singlet oxygen ( 1 O 2 ) generation. Unambiguously validated by in situ XPS and density functional theory (DFT) calculations, the S-scheme charge-transfer pathway efficiently accelerated spatial carrier separation while preserving maximum redox potentials. Consequently, the composite rapidly degraded the parent tetracycline hydrochloride within 20 min and achieved a mineralization efficiency of 52.5%, exhibiting outstanding degradation performance. Crucially, mechanism studies and density functional theory analyses have demonstrated that this highly selective reaction process, driven primarily by 1 O 2 as the dominant reactive oxygen species, is essentially determined by the energy levels of the specific molecular orbitals of the substrate. Pathway elucidation, coupled with in silico predictions and empirical phytotoxicity bioassays, comprehensively confirmed the substantial reduction in intermediate ecotoxicity. Ultimately, the scientific value of this work lies in providing deep mechanistic insights into S-scheme-driven selective oxidation, offering a robust and sustainable paradigm for designing targeted detoxification systems in wastewater treatment.

An efficient analytical scheme for detecting six purines in human serum samples was proposed by coupling a cyclodextrin polymer-based solid-phase microextraction (SPME) fiber with high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The cyclodextrin polymer coating provides abundant porous adsorption sites and cyclodextrin-assisted host-guest recognition toward nitrogen-rich purine structures, enabling efficient enrichment of highly polar purines from complex serum matrices. Compared with commercial fibers, the prepared fiber exhibited enhanced extraction performance, yielding analyte peak-area responses that were 3–267 times higher under identical experimental conditions. The method showed good linearity over the range of 1–2000 μg l -1 , low limits of detection of 0.05–3.3 μg l -1 , and satisfactory apparent spiked recoveries of 77.0–112.0%. Acceptable reproducibility was obtained with relative standard deviations of 1.49–17.4% for single-fiber repeatability and 2.60–14.0% for fiber-to-fiber reproducibility. The use of SPME and a small desorption volume further reduces solvent consumption and sample-preparation waste, supporting the potential green analytical features of the proposed method. Application of the method to human serum samples was performed as a preliminary demonstration of the method feasibility for real biological sample analysis. Overall, the proposed method offers a sensitive, and practical analytical approach for purine metabolite determination in biological samples, with promising potential for future clinical and metabolic investigations after further studies with larger sample cohorts.

Formaldehyde as a common indoor volatile organic compound (VOC) poses serious health risks to humans. Therefore, developing efficient formaldehyde adsorbents is essential for improving indoor air quality. Recently, zeolitic imidazolate framework (ZIF)-based adsorbents have attracted significant attention due to their high efficiency in formaldehyde removal. In this work, cellulose nanofiber (CNF) was used as biomass templates to in situ grow ZIF-8, forming a ZIF-8@CNF filter with enhanced adsorption capacity. The physical–chemical properties of ZIF-8@CNF were investigated using SEM, XRD, FTIR and XPS. The results demonstrate that the successful self-assembly of ZIF-8 crystals onto CNF results in a ZIF-8@CNF filter with a high specific surface area and abundant pore structures. Meanwhile, the ZIF-8@CNF filter demonstrated remarkable formaldehyde adsorption capacity, and achieved 88.32% removal of formaldehyde within 6 h. Additionally, the filter maintains stable structural integrity while retaining over 70% of the formaldehyde adsorption capacity after undergoing five adsorption–desorption cycles, demonstrating outstanding reusability. Furthermore, the adsorption of formaldehyde by the ZIF-8@CNF filter relies on its internal layered porous structure and noncovalent interactions with formaldehyde molecules. Therefore, the as-prepared ZIF-8@CNF filter offers an effective solution for indoor formaldehyde removal.

Spray drying and spray freeze drying induce distinct particle structure. • IGC is highly effective in resolving molecular-level surface characteristics. • IGC-ID reveals surface leucine enrichment and elevated dispersive energy. • IGC-FC quantifies hydrophilic site reduction and maps polar surface areas. • Surface energetics serve as a quantitative predictor for wetting and release. The unpredictable wettability of pharmaceutical microparticles, often stemming from complex phase transitions during processing, frequently eludes conventional unidimensional assessments of surface hydrophilicity. In this study, mannitol-leucine microparticles were fabricated via spray drying and spray freeze drying. Their structural properties—including morphology, particle size, and polymorphism—were systematically correlated with surface energetics (dispersive energy, acid–base characteristics, and hydrophilic site distribution) as delineated by inverse gas chromatography (IGC). Increasing leucine content induced pronounced surface wrinkling, sustained crystalline stability, and resulted in larger particle sizes in spray-dried samples. Conversely, spray-freeze-dried particles maintained a relatively uniform morphology but exhibited unstable δ-mannitol polymorphs with enhanced dispersibility. IGC analysis uncovered that leucine enrichment elevated dispersive surface energy, attenuated surface basicity, and diminished the hydrophilic surface area, with these effects being more pronounced in the spray-dried samples. Crucially, both the absolute hydrophilic surface area and the fractional distribution of hydrophilic domains were identified as key determinants modulating particle wettability and release behavior. This study highlights the capacity of IGC to resolve multiparametric surface energetics, thereby advancing the mechanistic understanding of pharmaceutical particle wettability through non-invasive, high-precision characterization.

Hyperuricemia is associated with dietary purine intake, dysregulated purine metabolism, and impaired uric acid excretion. This study aimed to isolate multifunctional LAB from fermented foods and apply the selected strain to enhance the functional potential of Smilax glabra Roxb. fermentation. Among 79 isolates, 46 were identified as LAB. Limosilactobacillus fermentum R-9 showed efficient degradation of inosine, guanosine, and adenosine, while exhibiting favorable gastrointestinal tolerance and safety-related probiotic properties. Its survival rates after simulated gastric and intestinal digestion were 82.28% and 67.18%, respectively. Genomics revealed genes related to nucleoside hydrolysis, purine/pyrimidine transport, nucleotide salvage, starch utilization, α-glucan metabolism, and β-glucosidase-related glycoside transformation, supporting the dual potential of R-9 for purine metabolism and adaptation to starch-rich S. glabra . L. fermentum R-9 was further used to ferment Smilax glabra Roxb., a starch-rich medicinal and edible plant material containing flavonoid glycosides. After 4 days of fermentation, total phenolics increased from 0.384 to 0.572 mg GAE/mL, and total flavonoids increased from 2.11 to 3.02 mg RE/mL. Xanthine oxidase (XOD) inhibitory activity increased from 16.58% to 70.81%, accompanied by enhanced DPPH and ABTS radical-scavenging activities. Astilbin reached 59.75 μg/mL, increasing by 33.79%. Mechanistically, L. fermentum R-9 fermentation promoted acidification, amylase and β-glucosidase activities, starch matrix disruption, and flavonoid release. These findings highlight L. fermentum R-9 as a promising starter for developing fermented Smilax glabra Roxb. products with enhanced antioxidant and xanthine oxidase inhibitory potential.

Flaxseed (Linum usitatissimumL.) is widely recognized as a functional food due to its rich nutritional composition; however, the metabolic basis underlying seed coat color variation remains unclear. In this study, we performed a broad-targeted metabolomics analysis of six flaxseed varieties (three brown and three yellow) grown at two distinct geographical locations. A total of 1456 metabolites were identified, among which flavonoids and phenolic acids were the most abundant differentially accumulated compounds. Eight metabolites consistently exhibited the largest differences across all comparison groups, and thus warrant further investigation as candidate markers in genetically controlled populations. Correlation analysis further indicated that these metabolites are associated with seed coat pigmentation and other developmental processes. Pathway enrichment revealed that the biosynthesis of caffeic acid derivatives, ferulic acid derivatives, and flavones/flavonols was differentially regulated between yellow and brown seeds. Collectively, our findings provide a comprehensive metabolomic landscape of colored flaxseeds and provide a foundation for future studies aimed at breeding flaxseed varieties with targeted color and nutritional traits.

A chloramphenicol (CAP) electrochemical sensor based on zinc tungstate and maghemite nanocomposites (ZnWO 4 /γ-Fe 2 O 3 ) is proposed. First, ZnWO 4 and γ-Fe 2 O 3 nanomaterials were synthesized using a hydrothermal synthesis method, then compositely modified onto glassy carbon electrodes to construct electrochemical sensors for measuring CAP. Under optimal conditions, the ZnWO 4 /γ-Fe 2 O 3 -modified electrode exhibits a stronger reduction peak current for CAP detection than the single-component electrode and demonstrates better electrocatalytic activity. The results demonstrate that ZnWO 4 /γ-Fe 2 O 3 /GCE exhibits a linear detection range of 8–1000 μM and a detection limit of 1.04 μM, demonstrating good selectivity in the presence of different interferers, as well as outstanding stability and reproducibility. ZnWO 4 /γ-Fe 2 O 3 /GCE was used to detect of CAP in milk samples, yielding satisfactory results.

Azo-pyridone dyes are attractive candidates for high-performance color filters owing to their rigid conjugated frameworks and high thermal stability. However, their practical application is often limited by strong intermolecular interactions that promote aggregation, resulting in broadened absorption profiles and compromised optical quality in thin films. Herein, we demonstrate that introducing N-heterocyclic substituents, morpholine and pyridine, onto the azo-pyridone core effectively disrupts π–π stacking and suppresses aggregation, enabling uniform dye dispersion in poly(methyl methacrylate) (PMMA) matrices. The resulting dye-PMMA composite films exhibit high optical transmittance (>90%), significantly improved yellow color purity and excellent thermal and photostability (Δ E < 3). Combined experimental and density functional theory (DFT) analyses reveal that the heterocyclic substituents modulate the molecular electrostatic potential distribution and reduce intermolecular interaction strength, accounting for the suppressed aggregation behaviour. Both morpholine and pyridine proved effective, confirming the generality of this substitution strategy. This work provides a practical molecular design approach based on N-heterocyclic modification for developing high-performance azo-pyridone dyes for advanced color filter applications.
