Emerging contaminants (ECs) such as pharmaceuticals pose increasing threats to aquatic environments and human health. Therefore, it is urgent to develop high-performance nanofiltration (NF) membranes for the efficient removal of ECs. In this work, we present a scalable and energy-efficient strategy for fabricating a novel covalent organic framework (COF)-based NF membrane under mild conditions. The membrane was prepared via electrospinning and subsequent electrostatic assembly, consisting of a porous PAN@TpPa support layer and a precisely deposited TpPa-SO 3 H selective layer. We employed a key interfacial engineering approach, in which protonated TpPa interlayer enhanced electrostatic interactions between layers, thereby forming a dense and negatively charged interface with outstanding long-term stability. The optimized membrane with 72 h TpPa growth time and 30 mg TpPa-SO 3 H loading, achieved a high rejection of 98.89 % for diclofenac sodium (DS) and an excellent permeance of 16.79 L m −2 h −1 ·bar −1 , outperforming commercial NF membranes. Moreover, the PAN@TpPa/TpPa-SO 3 H composite membrane exhibited remarkable long-term stability and superior antifouling performance. Molecular dynamics simulations revealed that the superior separation performance results from the synergistic effects of size sieving and Donnan exclusion. This work provides a mild and scalable interfacial engineering strategy for developing COF-based NF membranes, demonstrating great potential for the effective removal of ECs from wastewater.

A novel method for determining α, β-unsaturated aldehydes (α, β-UAs) in edible oils was proposed, utilizing 2,4-dimethylpyrrole (2,4-DMP) derivatization followed by UV–vis analysis. The optimal detection wavelengths were identified as 580 nm for α, β-monounsaturated aldehydes (α, β-MUAs) and 680 nm for α, β-diunsaturated aldehydes (α, β-DUAs). The reaction mechanism was confirmed by Fukui function and hydrogen nuclear magnetic resonance ( 1 H NMR) analysis, demonstrating formation of enamine as the final product. Derivatization conditions were optimized for rapid and reproducible results. The proposed method demonstrated excellent sensitivity, with limits of detection (LOD) and quantification (LOQ) for α, β-MUAs at 0.0038 μmol/mL and 0.0117 μmol/mL, and for α, β-DUAs at 0.0043 μmol/mL and 0.0129 μmol/mL, respectively. Compared to the p-anisidine value ( p-AV ) and high-performance liquid chromatography (HPLC) based methods, the proposed method showed several advantages in shorter derivatization time, simplified operation, high throughput potential and lower toxicity. This method provides an efficient tool for α, β-UAs detection, which is crucial for ensuring oil quality and safety.

Lanthanide complexes of sufficient luminescence and stability are highly desirable for a wide variety of fields. We successfully synthesized a tetrakis(β-diketonate) complex, PPN[Eu(TTA)4] (TTA: thenoyltrifluoroacetone, PPN: bis(triphenylphosphine)iminium). The as-synthesized complex exhibits superior luminescence properties compared with its sodium analog (Na[Eu(TTA)4]) with a higher PLQY (77.4% vs 21.6%) and an extended fluorescence lifetime (0.61 ms vs 0.22 ms) as well as the enhanced stability including a higher thermal decomposition onset (280 °C) and markedly greater photostability (>95% intensity retained after 120 h sunlight). The enhanced photoluminescence is attributed to the PPN+, which reinforces molecular rigidity to suppress nonradiative decay and optimizes Eu3+ coordination microenvironment to promote ligand-to-metal energy transfer. When applied to latent fingerprint (LFP) visualization, PPN[Eu(TTA)4] emits high-contrast red luminescence under 365 nm ultraviolet (UV) excitation, enabling clear resolution of all three levels of fingerprint features (ridge patterns, detail points, and sweat pores) on diverse substrates (porous, nonporous, and semiporous). Preliminary studies further demonstrate that PPN[Eu(TTA)4] possesses efficient X-ray radioluminescence, suggesting potential cross-application in hidden fingerprint detection. This work clarifies the critical role of PPN+ in regulating Eu3+ complex performance and provides a novel strategy for developing high-performance luminescent materials for forensic science and optical engineering.

Yeast and oat β-glucans differently influence extruded corn starch structure. • Yeast β-glucan addition before extrusion increases structural ordering. • Yeast β-glucan addition before extrusion promotes higher resistant starch formation. • Systems containing yeast β-glucan show relatively lower starch digestibility. • Yeast β-glucan is associated with a lower estimated glycemic index. Yeast β-glucan and oat β-glucan exhibit distinct molecular architectures that may differently regulate starch structure and digestibility during food processing. This study aimed to compare the effects of these two β-glucans incorporated before and after extrusion on the physicochemical properties, multiscale structure, and in vitro digestibility of extruded corn starch. Extrusion significantly decreased the relative crystallinity of corn starch and transformed its crystalline structure to a V -type pattern. Incorporation of β-glucans before extrusion led to more pronounced interactions between starch and β-glucan molecules than post-extrusion addition. Samples containing yeast β-glucan exhibited lower water solubility, higher short-range ordered structure, and higher relative crystallinity values than those containing oat β-glucan, indicating the formation of a more rigid structure. Moreover, the findings on rheology and pasting properties showed that the former system had higher viscosity than the latter, further confirming stronger structural reinforcement in systems incorporating yeast β-glucan before extrusion. Finally, the starch system containing yeast β-glucan exhibited a higher resistant starch content (32.09%) and lower estimated glycemic index (83.80 ± 0.11) compared with those containing oat β-glucan (28.34%, 84.96 ± 0.21), indicating greater digestion resistance. These results suggest that the molecular architecture of β-glucans and their timing of incorporation may influence the structural organization and digestion behavior of extruded starch systems.

Aqueous zinc-ion batteries (AZIBs) as promising candidates for grid-scale storage are constrained by the poor conductivity and structural instability of manganese dioxide (MnO 2 ) cathodes during cycling. Herein, we report a rationally designed cathode comprising β-MnO 2 nanorods intimately decorated with reduced graphene oxide (β-MnO 2 @rGO) through an in-situ hydrothermal and thermal activation process. The one-dimensional β-MnO 2 nanorods provide shortened diffusion pathways for H + /Zn 2+ ions, while the conformal rGO network establishes a three-dimensional conductive skeleton that enhances electronic transport and buffers volumetric expansion during cycling. X-ray photoelectron spectroscopy (XPS) confirms the formation of robust Mn-O-C interfacial bonds, which facilitate charge transfer and mitigate manganese dissolution. The optimized β-MnO 2 @rGO-30 exhibits a high reversible specific capacity of 387 ± 3.0 mAh g −1 at 0.1 A g −1 and maintains 89 ± 1% capacity retention after 6000 cycles at 1.0 A g −1 . A sequential insertion mechanism, beginning with H + intercalation followed by Zn 2+ storage, with excellent structural reversibility, is elucidated by ex-situ spectroelectrochemical analysis. This work provides a viable strategy for designing high-performance MnO 2 -based cathodes through synergistic nanoengineering and conductive hybridization for advanced AZIBs. This work constructs β-MnO₂@rGO heterostructures with covalent Mn-O-C bonds to overcome poor conductivity and structural instability in AZIB cathodes. The rGO scaffold enhances reaction kinetics, buffers volume change, and suppresses Mn dissolution. The optimized electrode delivers a high reversible specific capacity, excellent capacitance retention and cyclic stability.

Traditional thermoset-based aramid fiber-reinforced composites (AFRCs) possess ultrahigh specific strength and puncture resistance but face intractable recycling issues due to their permanent cross-links, leading to waste accumulation and underutilization of aramid fibers (AFs). Although dynamic covalent chemistry-based thermosets offer a sustainable alternative, balancing their mechanical performance with recyclability and realizing upcycling remains a bottleneck. Herein, we design a chemically recyclable polyurea thermoset (PUA–PBAEx) based on reversible β-amino ester networks, which achieves high mechanical strength (∼74.4 MPa for PUA–PBAE1.5) and good thermal stability. The PUA–PBAEx can serve as an ideal matrix for AFRCs (PUA–PBAEx/AF-y), delivering exceptional puncture resistance and specific strength. Notably, the PUA–PBAEx/AF-y composite can be fully depolymerized under mild acidic conditions, enabling the full recovery of intact AFs and conversion of the degraded linear polyurea into a high-performance reusable adhesive with robust adhesion (∼13.8 MPa) to multiple substrates. This work provides a circular economy strategy for next-generation AFRCs that integrates high mechanical performance, closed-loop recycling, and upcycling capabilities.

β-Lg can simultaneously load and protect the three flavonoid compounds, namely Isl, Gen, and Bai. • In terms of stability, the β-Lg-multilinked compound shows a better protective effect against the three types of flavonoids. • A spectroscopic approach was adopted to elucidate the binding mechanisms of three flavonoids with β-Lg. • The conformational characteristics of the complexes were investigated through molecular docking and dynamics simulations. This study elucidates the interaction mechanisms of Isoliquiritigenin (Isl), Genistein (Gen) and Baicalein (Bai) with β-lactoglobulin (β-Lg), with a focus on the protein's capacity for the co-encapsulation and stabilization of these flavonoids. The binding mechanisms were characterized using fluorescence spectroscopy, high-performance liquid chromatography, non-radiative energy transfer analysis, molecular simulations. The results demonstrated that the binding affinity ( K a ) followed the order Bai > Gen > Isl. Accordingly, the calculated binding distances for Isl, Gen and Bai were 5.36 nm, 4.49 nm, and 4.20 nm, respectively. β-Lg is capable of co-encapsulating two or three flavonoids simultaneously. The most stable ternary complex (β-Lg-Isl-Gen-Bai) formed when the flavonoids were added in the sequence of Bai, Isl, and then Gen. The β-Lg multi-ligand complex provided superior protection for Isl, Gen, and Bai compared to their respective single-ligand complexes across all tested parameters: stability, antioxidant capacity, and α-amylase inhibition. For Isl, the retention rate improvement under storage stability is the largest, reaching 73.86 ± 1.04%; for Gen, the retention rate improvement under light stability is the largest, reaching 75.22 ± 0.77%; and for Bai, the retention rate improvement under thermal stability is the largest, reaching 71.90 ± 1.02%. β-Lg simultaneously encapsulates and stabilizes three flavonoids Isl, Gen, Bai, serves as a natural and potent protein carrier for these bioactive compounds, and offers theoretical support for their protection against degradation.

A green oxidative-gelation strategy was developed to transform water-insoluble paramylon (β-1,3-glucan) from Euglena gracilis into an off-white hydrogel (EPG) without cross-linkers. Alkaline dissolution, acid-neutralization, and mild H2O2 oxidation (8%, v/v, 5 h) disrupted crystallinity and reduced molecular weight while preserving the β-1,3-glycosidic backbone and triple-helix conformation. Systematic optimization based on dry weight recovery, viscosity, and SEM morphology identified 5 h as the optimal oxidation time. EPG exhibited superior antioxidant capacity compared to native paramylon, scavenging 88.1% of DPPH and 98.0% of ABTS radicals at 2.5 mg·mL–1. Oral administration in mice confirmed the safety and efficacy of EPG in enhancing hepatic antioxidant enzyme activity (SOD increased by 165%, MDA decreased by 52.6%). This solvent-free approach provides a scalable route for producing clean-label, high-performance polysaccharide hydrogels suitable for food and biomedical applications.

This study investigated the adsorption behavior of shikimic acid (SA) on a newly biosynthesized polymeric nanocomposite adsorbent (FPCD-COOH-BA), which is mild to prepare and cost-effective for wastewater treatment. Using a detailed statistical-physical model, we found that SA is physisorbed via van der Waals forces and hydrogen bonds. A thermodynamic analysis showed that the process was spontaneous and endothermic; the entropy evaluation indicates an increase in the system’s disorder before half saturation and a decrease after half saturation is exceeded. These results provide new insights on SA adsorption at the molecular level and highlight the importance of statistical physics in the interpretation of adsorption phenomena.

To improve the permeability-selectivity balance in polyamide nanofiltration membranes, a dual-charged composite membrane (PES-CS/SBE-β-CD-PA) was fabricated via interfacial polymerization on a self-assembled CS/SBE-β-CD interlayer designed to regulate the interfacial availability and transport of PEI monomers during polyamide formation, yielding a selective layer with a lower apparent cross-sectional thickness (approximately 173 nm) and more uniform morphology. The negative potential of the interlayer-terminated surface before IP (−9.8 mV), the positive potential of the final PA surface (15.63 mV), and the sequential fabrication process support the designed negative-interlayer/positive-PA configuration. The optimized membrane exhibits a molecular weight cut-off of 445 Da, an average pore size of 0.51 nm, and MgCl 2 and MgSO 4 rejections of 94.00% and 91.34%, respectively, while maintaining a water permeance of 15.20 L m −2 ·h −1 ·bar −1 . The morphology, pore-size, and charge results support a separation mechanism combining steric/hydration effects with charge-dependent Donnan partitioning. In addition, the membrane shows improved antifouling properties and stable separation performance during 72 h continuous filtration under the tested conditions. This work presents an effective interfacial-regulation strategy for constructing nanofiltration membranes with balanced separation and antifouling performance.

Postoperative delirium (POD) is a severe postoperative neurocognitive complication associated with neuroinflammation and blood-brain barrier dysfunction. As a clinically relevant circulating biomarker for POD, S100-β detection is of great importance for accurate diagnosis and progression evaluation. Traditional approaches generally rely on converting antigen-antibody recognition events into the changes in labeled signal molecules, while neglecting the intrinsic charge properties of S100-β. Herein, a bioinspired microchannel-based ion current rectification (ICR) sensor was developed for sensitive S100-β detection, where S100-β antibodies were immobilized on the microchannel surface to simulate natural molecular recognition processes. The low isoelectric point of S100-β (∼4.7) renders the protein negatively charged under neutral conditions. Specific antigen and antibody recognition increased the interfacial negative charge density of the microchannel, thereby facilitating cation transport and enhancing the rectification response under an applied electric field. This process mimics the biological processes of channel opening and ion influx in living systems. The detected rectification ratio (RR) values was linearly correlated with the logarithm of S100-β concentration in the range of 0.01 ∼ 5.0 ng/mL with a detection limit of 4.0 pg mL −1 (S/N = 3). The sensor also showed good selectivity, as well as high stability with small RSD of 2.45%. The proposed sensor was successfully applied to the clinical serum analysis, showing good agreement with enzyme-linked immunosorbent assay and high recovery rates of 97.8% - 104.0%. This work provides a promising strategy for POD-related biomarker analysis and broadens the application of bioinspired microchannel-based ICR sensors in clinical diagnostics and bioanalytical sensing.

The promotion of covalent grafting of seven structurally distinct polyphenols to β-Lactoglobulin (β-LG) via cold plasma (CP) treatment, and their influence on functionalities and antigenicity of β-LG were systematically investigated. Results indicated that covalent β-LG-polyphenol conjugates were generated after undergoing 45 s of CP treatment, with the highest (135.49 ± 1.87 μmol/g) and lowest (2.56 ± 1.43 μmol/g) polyphenol content in β-LG-(−)-epigallocatechin gallate (β-LG-EGCG) and β-LG-syringic acid (β-LG-SA) conjugates, respectively. This result clearly demonstrated that the binding capacity is directly related to the number of phenolic hydroxyl (-OH) groups in polyphenols. Multispectral analysis revealed that the β-LG's spherical conformation unfolded upon covalent grafting with polyphenols. Further analysis of functionalities and antigenicity revealed that improvement in functionalities and reduction in antigenicity of β-LG was positively correlated with the grafted polyphenol content. The β-LG conjugates modified with EGCG displayed a maximum decrease in antigenicity (58.40 ± 1.03 %), a nearly seven-fold increase in DPPH, and a five-fold increase in ABTS free radical-scavenging capabilities when compared to native β-LG. According to LC-MS/MS and immunoblot analysis, the primary cause of the decrease in antigenicity was the disruption of the linear IgE epitope in β-LG as a result of conjugated EGCG's masking and steric hindrance impact. These findings demonstrate that CP is a reliable method for promoting covalent conjugation between polyphenols and proteins. Moreover, the binding affinity was found to be positively correlated with the number of -OH groups present in the polyphenol, which is a key structural determinant for enhancing functional properties and for reducing the antigenicity of the resulting protein-polyphenol complexes.
