Naringin (NRG) is a bioactive substance with important pharmaceutical and industrial value. However, the major challenges in the separation of NRG arise from the complexity and low concentration of crude extracts. In this work, by integrating the advantages of magnetic separation, MOFs@COFs composite materials, and surface molecular imprinting strategy, a new kind of magnetic MOF@COF-based boronate-affinity molecular imprinted adsorbent (NH2-MIL-68-Fe3O4@COFs@BA-MIPs) was constructed. Magnetic NH2-MIL-68 substrates were prepared by the solvothermal method, aldehyde-functionalized by surface modification with 2,4,6-triformylphloroglucinol (Tp). Then, a covalent organic framework shell was grown on the surface of substrates via the Schiff base reaction. Finally, a boronate-affinity imprinted polymer was prepared via surface-initiated atom transfer radical polymerization (SI-ATRP). The as-prepared adsorbent features rapid magnetic separation. In addition, the high-density boronate-imprinted recognition sites and porous structure endow the material with a fast adsorption rate (reaching equilibrium about 60 min), a high adsorption capacity (57.29 μmol g–1), and good retention performance (92.79%) after six adsorption–desorption cycles at 308 K under pH 8.0. Moreover, the extraction rate of crude NRG by NH2-MIL-68-Fe3O4@COFs@BA-MIPs reached 93.61%. This study provides a design strategy for constructing NRG adsorbents with rapid magnetic response and has important application value in the specific separation and purification of flavonoids.

Metal ion-enzyme tandem systems hold immense potential for biocatalysis, environmental remediation, and medical therapy, yet their development is hindered by inherent incompatibility, low ion concentration, and spatial distance barriers between metal ions and enzyme, limiting the maximization of metal ion catalytic potential. Here, we developed a convenient one-step doping strategy to achieve spatial separation of high concentration metal ions and enzymes within single metal-organic frameworks (MOFs). Catalytically active metal ions partially replace MOF sites through ligand coordination, while enzymes are in-situ encapsulated (enzyme@M-MOFs), maintaining structural integrity and enhancing stability. This design enables efficient chem-bio tandem reactions by preventing mutual inactivation and accelerating reaction rates due to distance shortening between metal ions and enzymes. The enzyme@M-MOFs exhibit good therapeutic effect in diabetic wound healing, establishing a new paradigm for catalytic medicine applications. The strategy's versatility is demonstrated by its successful application with a range of metal ions (Fe 2+ , Mg 2+ , Cd 2+ …) as catalysts or enzyme promoters. By transforming incompatible systems into compatible tandem platforms, this work offers a universal approach for efficient chemical-enzyme tandem catalysis, unlocking novel possibilities in biocatalysis and beyond.

Hexagonal boron nitride (h-BN) is inherently hydrophobic and lacks active functional groups on its surface. In this study, we modified h-BN with phytic acid and chitosan to create BN@PA-CS particles. These particles integrated into an aqueous polyurethane (WPU) matrix, along with the DIDOPO flame retardant, to form the WPU/BN@PA-CS/DIDOPO nanocomposite. We investigated the composite’s flame retardancy, thermal stability, rheological properties, and mechanical properties. The results demonstrated that BN@PA-CS and DIDOPO exhibit a significant synergistic effect in both gas and condensed phases for flame retardancy. When the mass fractions of BN@PA-CS and DIDOPO were 2 wt% and 7 wt% relative to WPU matrix, the optimal formulation WPU/BN@PA-CS2/DIDOPO7 achieved a UL-94 V-0 rating and increased the limiting oxygen index (LOI) to 24.2%. Additionally, the peak heat release rate (pHRR) and total heat release (THR) decreased by 49.3% and 66.1%, respectively, compared to pure WPU. Rheological and mechanical measurements indicated that the formulation WPU/BN@PA-CS2/DIDOPO7 exhibited a compatible combination of tensile stiffness, ductile toughness, and melt flow behaviour relative to other composite groups.Therefore, the DIDOPO/BN@PA-CS composite strategy provides experimental observations and mechanistic speculation for developing high-performance flame-retardant polyurethane composites, optimizing synergistic effects at specific ratios to enhance flame retardancy and mechanical properties.

The genusSchizothoraxcomprises an important group of freshwater fishes in Xinjiang (China); however, detailed information on their skeletal anatomy remains limited. In this study, we combined micro-computed tomography (micro-CT) and traditional skeletal preparations to examine and compare the osteological characteristics of three representativeSchizothoraxspecies:Schizothorax biddulphi,Schizothorax eurystomus, andSchizothorax curvifrons. Distinct variations were observed in several skeletal structures, including the cranium, pharyngeal teeth, fin-supporting elements, and vertebrae. Among the three species,S. biddulphiandS. eurystomusshowed generally similar skeletal architectures, whereasS. curvifronsexhibited more pronounced osteological differences. These findings provide new comparative osteological data forSchizothoraxspecies and offer a morphological reference for future studies on the taxonomy, systematics, and conservation of these freshwater fishes.

Conventional water treatment relies on sequential flocculation and disinfection, which inflates infrastructure costs and heightens the risk of disinfection byproduct formation. Here, we report a magnetic lignin-based flocculant (LS-DMC-AM@Fe3O4) that integrates flocculation, sterilization, and rapid magnetic separation within a single material. The composite was synthesized by thermally initiated graft copolymerization of methacryloyloxyethyl trimethylammonium chloride (DMC) and acrylamide (AM) onto sodium lignosulfonate (LS), followed by incorporation of Fe3O4nanoparticles (NPs) at 15 wt% loading; the product exhibited a saturation magnetization of 12.8 emu g−1. LS-DMC-AM@Fe3O4achieved 98.2% kaolin turbidity removal at 1 mg L−1and 98.6%E. coliremoval at 8 mg L−1, and displayed a markedly broader effective dosage window than its non-magnetic analog. We attribute this broadened window to Fe3O4-enhanced membrane disruption, which liberates anionic intracellular contents that buffer excess cationic charge and thereby suppress restabilization. The bactericidal efficiency reached 90% at 18 mg L−1, 1.6-fold higher than LS-DMC-AM, governed by a synergistic dual mechanism: quaternary ammonium contact-killing coupled with Fe3O4NP-induced intracellular reactive oxygen species (ROS) accumulation. Under an external magnetic field, flocs underwent rapid phase separation and displayed enhanced shear-regrowth capacity (E. colifloc recovery factor: 53% vs. 26%); Fe3O4NPs were recovered at >95% efficiency over two cycles. Despite higher unit production costs, LS-DMC-AM@Fe3O4delivers competitive per-unit-volume treatment economics through its ultralow effective dosage and magnetic seed recyclability. These results establish a viable strategy for engineering multifunctional, recyclable flocculants from industrial lignin waste.

The pursuit of full-spectrum white light-emitting diodes (WLEDs) with high color rendering is often hampered by the “cyan gap”, a spectral deficiency that compromises light quality. Herein, we narrow this gap by developing a novel yellow-green-emitting Y 2- x CaScAl 3 SiO 12 :0.06Ce 3+ (YCSASO:0.06Ce 3+ ) garnet phosphor. A series of YCSASO: x Ce 3+ ( x = 0.01-0.16) garnet phosphors is synthesized and systematically studied. Structural analysis confirms that all phosphors crystallize in a pure cubic garnet structure, with Ce 3+ ions occupying the dodecahedral sites of Y 3+ and leading to a slight lattice expansion. Upon 450 nm excitation, the YCSASO: x Ce 3+ phosphors exhibit a wide asymmetric band characteristic of the Ce 3+ emission (5d 1 →4f). The tunability of the emission color across the green-to-yellow region is achieved through variation of Ce 3+ concentration, because of enhanced crystal field splitting and resonant energy transfer. YCSASO:0.06Ce 3+ as the optimal composition effectively narrows the cyan gap, exhibiting a broad emission band centered at 549 nm with a full width at half maximum (FWHM) of 124 nm, an internal quantum efficiency (IQE) of 56.3%, and an external quantum efficiency (EQE) of 28.4%. First-principles calculations indicate that incorporating Ce 3+ 5d states narrows the host bandgap, facilitating efficient electron transitions. This phosphor achieves stable thermal performance by maintaining 59% of its initial intensity at 423 K and remarkable color stability with a chromaticity shift as low as Δ E = 5.1 × 10 −3 . A prototype WLED based on this yellow-green phosphor, a 455 nm blue LED chip, and a red-emitting CaAlSiN 3 :Eu 2+ phosphor maintains excellent stability for at least 12 h and generates high-quality warm white light, achieving a color rendering index (Ra = 92.2), a correlated color temperature (CCT = 3490 K), and a luminous efficacy of 52.6 lm/W. This work validates the strategic use of the yellow-green YCSASO:0.06Ce 3+ phosphor to narrow the cyan gap, paving the way for advanced full-spectrum lighting.

Cyclohexyl-functionalized diglycolamides with tailored alkyl side chains demonstrate full compatibility with alkane diluents. • Cyclohexyl-functionalized diglycolamides exhibit high extraction efficiency and selectivity for Sr 2+ . • Extraction and complexation studies confirmed a neutral complexation model for Sr 2+ extraction. • Simulation experiments demonstrate a promising application in separating Sr 2+ from high level liquid waste. To overcome the limitations of poor lipophilicity in alkane diluents associated with tetracyclohexyl-substituted diglycolamide (TCHDGA), four asymmetric diglycolamide ligands with two cyclohexyl and varying alkyl chains were synthesized: N,N -dibutyl- N′,N′ -dicyclohexyl diglycolamide ( L I ), N,N -dihexyl- N′,N′ -dicyclohexyl diglycolamide ( L II ), N,N -dioctyl- N′,N′ -dicyclohexyl diglycolamide ( L III ), and N,N -didodecyl- N′,N′ -dicyclohexyl diglycolamide ( L IV ). Using n -dodecane as the diluent, their extraction behavior toward Sr 2+ in HNO 3 solution was investigated. Although L I and L II are soluble in n -dodecane, both formed a third phase upon contact with HNO 3 solution at concentrations exceeding 1.0 mol/L. Ligands L III and L IV exhibited significantly stronger Sr 2+ extraction than N,N,N′,N′ -tetraoctyl diglycolamide (TODGA). The D Sr values of L III and L IV reached 231 and 181 at the acidity of 2.5 and 3.0 mol/L, respectively—approximately 98 and 56 times higher than that of TODGA under identical conditions. Slope analysis indicated the formation of a 1:3 (metal-to-ligand) complex during extraction, which was further corroborated by ESI-MS, FT-IR, and ITC analyses. At 25 °C, Sr 2+ extraction by these ligands was found to be an exothermic, entropy-decreasing, and spontaneous process, following a neutral complexation mechanism. Quantitative recovery of Sr 2+ was achieved via a two-stage stripping process using 0.01 mol/L HNO 3 . Extraction tests with simulated high-level liquid waste further confirmed that L III enables efficient and selective separation of Sr 2+ from coexisting ions. Furthermore, density functional theory calculations revealed that, compared to L IV , L III possesses a more negative electrostatic potential, higher bond orders, and more negative binding energy, indicating a stronger tendency to form stable complexes with Sr 2+ , in good agreement with the extraction experimental results.

HA greatly suppresses ·OH and halves 1 O 2 formation compared with plastic-derived DOM. • PS-DOM shows over threefold stronger ·O 2 − inhibition than PE-DOM. • Aromatic ketones in plastic-derived DOM prolong 3 DOM ⁎ lifetime while HA moieties quench ROS. • Energy and electron transfer pathways define DOM-controlled ROS dynamics. Porous carbon-based photocatalysts offer a promising platform for visible light-driven water treatment, yet dissolved organic matter (DOM) from natural and anthropogenic sources can substantially modulate reactive oxygen species (ROS) dynamics, affecting pollutant degradation. A systematic understanding of how DOM composition and molecular structure influence ROS generation remains limited. Here, a boron-doped covalent triazine framework (B-CTF) was employed as a model photocatalyst, with humic acid (HA) and microplastic-derived DOM (PE-DOM, PS-DOM) representing natural and anthropogenic coexisting components. Adsorption experiments revealed that B-CTF exhibited enhanced maximum adsorption capacities ( q m ) for HA, PE-DOM, and PS-DOM and accelerated intraparticle diffusion, demonstrating efficient DOM-catalyst interfacial interactions. ROS analysis identified 1 O 2 and ·OH as dominant species, strongly modulated by DOM. HA suppressed ·OH generation by 2.00 × 10 −2 h −1 , ∼1.0 order of magnitude higher than PE-DOM and PS-DOM, and reduced 1 O 2 formation nearly twofold relative to plastic-derived DOM. PS-DOM caused the strongest ·O 2 − inhibition (8.34 × 10 −2 h −1 , 3.3-fold higher than PE-DOM), while PE- and PS-DOM moderately suppressed overall ROS. Fluorescence component analysis indicated that aromatic ketones in plastic-derived DOM facilitate ROS persistence, while humic-like substances in HA promote ROS quenching, highlighting the decisive role of DOM composition in interfacial ROS regulation. These findings elucidate the mechanistic pathways by which distinct DOM types regulate energy and electron transfer at the B-CTF interface, thereby controlling ROS yields, lifetimes, and spatial distribution. They also provide quantitative guidance for designing DOM-resilient photocatalysts and developing targeted water treatment strategies. Natural and anthropogenic DOM (HA, PE-DOM, PS-DOM) critically regulate ROS formation, reactivity, and persistence in B-CTF photocatalytic systems via distinct energy- and electron-transfer pathways. Specific structural components within DOM quench or sustain ROS, thereby reshaping degradation routes and pollutant removal efficiency. These mechanistic insights highlight the structure-activity relationship governing DOM + B-CTF interactions and provide guidance for developing photocatalysts with resilience to DOM interferences in complex aquatic environments.

Both the 2D titanium carbide (Ti 3 C 2 T x ) MXene and the 3D rare earth doped zirconium-based metal organic framework (Ln 3+ @UiO-66, MOF) were constructed on the colorless transparent polyimide (CPI) film to form the heterojunction multifunctional nano-coating via a one-pot immersion method in order to improve the UV resistance of CPI. Firstly, the S/CPI film was obtained via the CPI being modified with silica (SiO 2 ) sol, and then the Ti 3 C 2 T x MXene was loaded onto the surface of the S/CPI film via the hydrogen bond, finally the Ln 3+ @UiO-66 was loaded onto the ultra-thin Ti 3 C 2 T x MXene nanosheets to obtain optimal sample (MXene/Ln 3+ @UiO-66-S/CPI). The transmittance of MXene/Ln 3+ @UiO-66-S/CPI is 93.33%, which is only 0.94% lower than that of S/CPI. The tensile strength and elongation of MXene/Ln 3+ @UiO-66-S/CPI are basically the same as those of S/CPI. The attenuation values of transmittance, tensile strength, and elongation for MXene/Ln 3+ @UiO-66-S/CPI film after 5000 equivalent sun hours (ESHs) UV irradiation are 2.44%, 10%, and 18%, respectively, i.e., this film gets both a high transparency and a super ultraviolet resistance. This may be attributed to the fact that the MXene/Ln 3+ @UiO-66 multifunctional nano-coating can absorb the UV light and undergo the down-conversion, weakening the UV irradiation intensity.

Exosomes, as extracellular vesicles, represent ideal biomarkers for liquid biopsy, enabling non-invasive, sensitive, and dynamic disease monitoring. Detection or profiling of exosomes are essential for advancing exosome-based cancer diagnostics or prognostic prediction. Here, we developed an enhanced electrochemiluminescence (ECL) biosensing platform that combines magnetic enrichment with catalytic hairpin assembly (CHA), an enzyme-free DNA amplification circuit triggered by the complementary sequences of CD63 aptamer (Apt), to achieve sensitive exosome detection. The enhanced ECL signal relies on a nanocomposite of a zirconium-based metal-organic framework (Zr-MOF) and water soluble gold nanoclusters (AuNCs), denoted as Zr-MOF/AuNCs. The platform exhibits a wide linear range (6.12 × 10² - 6.12 × 10⁷ particles/mL) and a low detection limit (187.4 particles/mL) for tumor-derived exosomes. Spike-recovery assays in complex serum matrices and high specificity confirm its robustness and clinical potential. By combining magnetic preconcentration, signal amplification via Zr-MOF and CHA, and Apt-mediated recognition, this work establishes a new paradigm for non-invasive cancer diagnostics.

A novel D-shaped optical fiber sensor, functionalized with folate receptor protein for specific folic acid capture, is developed in this study. By employing a gold nanorod vacancy-filling amplification strategy, an exceptional sensitivity of 6.5 nm/ (ng mL -1 ) and an ultralow limit of detection of 0.012 ng/mL is achieved. The tunable nanoparticle occupancy time ensures stable detection sensitivity across varying analyte concentrations. This label-free sensing platform demonstrates robust specificity and excellent stability, offering significant potential for biomedical diagnostics and adaptable detection of diverse biomolecules. : Folic acid is an essential micronutrient for human growth, and either its excess or deficiency can provoke adverse physiological effects. Therefore, the development of a rapid and highly sensitive detection platform for folic acid is of substantial practical importance. In this study, a D-shaped optical fiber sensor is functionalized with a folate receptor protein to capture target analytes through specific ligand–receptor interactions. Vacant binding sites are subsequently occupied by functionalized gold nanorods for amplifying the fiber’s surface plasmon resonance (SPR) response. The incorporation of gold nanorods yields an enhanced SPR wavelength shift, leading to a significant improvement in detection sensitivity. The tunable nanoparticle occupancy time ensures the stability of detection sensitivity at various folic acid concentrations. Stability and specificity tests corroborated the sensor’s robustness and selectivity. The proposed device achieved a sensitivity of 6.5 nm/ (ng· mL -1 ) and a limit of detection of 0.012 ng/mL toward folic acid. This label-free, high-sensitivity approach offers considerable potential for biomedical applications. A highly flexible fiber-optic sensor with a broad detection range for acid sensing is developed by combining nanorod vacancy-filling with surface plasmon resonance (SPR) technology.

Co-treating zinc hydrometallurgical residues with high Fe, Zn, and Al contents in lead smelting systems poses significant challenges for slag property control, thereby adversely affecting process efficiency and industrial sustainability. In this study, the effects of CaO/SiO 2 mass ratio of 0.2–0.6, ZnO content of 10–30 wt%, and Al 2 O 3 content of 2–10 wt% on viscosity ( η ), activation energy for viscous flow ( E η ), and slag structure for “Fe x O”-SiO 2 -CaO-ZnO-5.5 wt%PbO-Al 2 O 3 system were systematically investigated. Increasing the CaO/SiO 2 mass ratio reduced η and E η at high temperatures because of silicate network depolymerization. At 1573 K, the proportion of monomeric [SiO 4 ] 4- units increased, leading to an increase in the NBO/Si value from 2.22 to 2.91. The slag with a CaO/SiO 2 mass ratio of 0.4 showed the most stable viscous-flow behavior at low temperatures and had the lowest T c (temperature at η = 0.5 Pa·s) of 1426 K. Increasing the ZnO content also reduced η and E η at high temperatures, and the NBO/Si value increased from 2.87 to 3.03 at 1573 K. Opposite trends exhibited at low temperatures due to the enhanced crystallization ability. The T c increased from 1413 K to 1475 K, always meeting the slag temperature range for lead smelting (＜1523 K). Al 2 O 3 acted as a network former in the studied slag, without showing amphoteric transition behavior. The NBO/Si value decreased from 3.07 to 2.50 as the Al 2 O 3 content increased. The T c of the slag containing 10 wt% Al 2 O 3 was 1573 K, exceeding the normal slag temperature range for lead smelting.
