ZIF-8 as multi-dentate crosslinking hub converts weak CS/γ-PGA complexes into robust dual-network hydrogel. • Ultra-large pores eliminate diffusion limitation (Da ≈ 0.001) with K m increase of only 2.2-fold. • HSP regression (R 2 = 0.76, p ≈ 0.0002) validates synergistic thermodynamic exclusion and size-sieving mechanism. • Immobilized α-Glu@PC/ZIF-8 enables ligand fishing of two α-glucosidase inhibitors via capture-wash-elute workflow. Herein, a composite hydrogel based on two natural macromolecules—chitosan (CS) and γ-poly(glutamic acid) (γ-PGA)—was developed, crosslinked by zeolitic imidazolate framework-8 (ZIF-8) nanoparticles, which serve as reactive crosslinking hubs to covalently connect the biopolymer chains for efficient immobilization of α-glucosidase (α-Glu). A carboxyl-terminated poly(ethylene glycol)–poly(glutamic acid) copolymer was first synthesized and its activated carboxyl groups underwent amidation with amino groups of CS to rapidly form a three-dimensional PC/ZIF-8 hydrogel. The effects of ZIF-8 content and CS concentration on micro-morphology, swelling behavior, and rheological properties were systematically investigated. ZIF-8-mediated crosslinking was essential for gel formation, enabling effective modulation of network density and pore architecture. The optimized hydrogel showed no inhibitory effect on α-Glu. Immobilized α-Glu@PC/ZIF-8 exhibited enhanced pH stability (retaining 53% and 70% activity at pH 4.0 and 9.0), outstanding storage stability (>90% after 4 weeks), excellent organic solvent tolerance (>90% in most solvents), and good reusability (near 100% activity over 6 cycles). Mass transfer studies confirmed that the designed crosslinking density provided efficient substrate/product diffusion channels, minimizing product inhibition. Hansen solubility parameter analysis revealed a synergistic “thermodynamic exclusion + size-sieving” mechanism for solvent tolerance. Coupled with HPLC, the immobilized enzyme successfully identified two α-glucosidase inhibitors—batatasin I and 2,4-dimethoxy-6,7-dihydroxyphenanthrene—from Dioscorea opposita Thunb. peel. This work demonstrates that rational chemical modification of natural macromolecular networks via MOF crosslinkers provides an effective strategy for constructing high-performance enzyme immobilization platforms.

TEMPO/NaClO/NaBr is applied to controlled degradation of fucoidan. • TEMPO/NaClO/NaBr enables efficient LMWF production from fucoidan in 0.5 h. • Galactose changes are consistent with possible C6 oxidation under TEMPO mediation • The TEMPO-free system caused 18.97% fucose loss and 6.13% sulfate loss. Low-molecular-weight fucoidan (LMWF) is highly desirable for food and pharmaceutical applications, yet conventional degradation methods often compromise its bioactive sulfate content. In this study, we employed a TEMPO/NaClO/NaBr system to degrade fucoidan under mild alkaline conditions and systematically investigated the degradation kinetics, structural changes, and anticoagulant activity of the resulting LMWF products. The degradation process was monitored by NaOH consumption and molecular weight distribution analysis. The optimal reaction time was determined to be 0.5 h, during which the molecular weight decreased from 337.4 kDa to 24.3 kDa, yielding LMWF with a relatively narrow molecular weight distribution (PDI = 1.08). Structural characterization by monosaccharide composition analysis, FT-IR, and 1 H NMR suggested that TEMPO-mediated oxidation favored oxidation at C6 primary hydroxyl groups, as indicated by changes in galactose and galacturonic acid contents, while no significant loss of total sulfate content was observed. In contrast, the non-selective NaClO/NaBr system caused substantial losses of fucose (18.97%) and total sulfate content (6.13%). Notably, the TEMPO-derived LMWF retained potent anticoagulant activity in the APTT assay while exerting a minimal effect on the PT pathway, suggesting a potentially lower bleeding risk. This study provides a promising strategy for the controlled preparation of LMWF with minimal loss of total sulfate content and a potentially favorable safety profile.

Carbon-electrode based mesoscopic perovskite solar cells (meso‑CPSCs) are known for their unique mesoporous skeleton structure. Understanding the growth dynamics of lead halide perovskite (PVSK) in the mesoporous skeleton has remained as one of the key tasks. Here in this article, we happen to observe that, air humidity could affect the growth process of PVSK in the mesoporous skeleton. When being treated at relatively higher moisture environment (RH≥70%), uneven crystallization is obtained, or PVSK tends to crystallize at the surface of carbon electrode, leaving voids at the buried interface, or that between PVSK and electron-transport-layer (ETL). Meanwhile, water molecules related intermediate PVSK phase is formed at the top part of the skeleton. In contrast, when being treated at relatively lower RH (≤30%), uniform PVSK loading is harvested in the mesoporous skeleton, leading to faster extraction of photo-generated charge carriers, and helping upgrade the average power conversion efficiency from 0.33% to 12.34%; subsequent three-step treatment and Ag deposition raise the champion PCE to 15.21%. Careful examination shows that, the uneven crystallization of PVSK correlates closely to the absolute humidity (AH) or the concentration of moisture molecules. High AH facilitates the upward transport of solute in PVSK precursor, and results in preferred crystallization in the upper region, which resembles the transpiration behavior in plants. This work reveals the importance of the control over moisture concentration during the PVSK crystallization process. Moisture molecules trigger a transpiration-like upward transport of precursor solutes, driving preferential perovskite crystallization near the carbon-electrode surface while leaving voids and poor contact at the buried perovskite/ETL interface, showing the importance of control over the humidity.

Sp 3 -type edge defects and sp 2 -type pentagonal defects were precisely engineered. • EDC prefers electron-donating ECs, while PDC favors electron-accepting ones. • π-π EDA interactions dominate the selective adsorption of ECs. • Defect configuration governs electronic matching for selective ECs removal. The persistent release of emerging contaminants (ECs) into water systems poses significant risks to human health and ecosystems. Adsorption using carbon-based materials offers a sustainable remediation strategy, yet the role of intrinsic defects in preferential contaminant removal remains poorly understood. Herein, we engineered two carbon-based materials with distinct defect configurations: one enriched with sp 3 -type edge defects (EDC) and another with sp 2 -type pentagonal ring defects (PDC), as unequivocally corroborated by aberration-corrected scanning transmission electron microscopy (ac-STEM) and complementary characterizations. Batch adsorption experiments were conducted using six ECs of opposite electronic nature, including antibiotics, DNA bases, and nanoscale plastics. Remarkably, PDC exhibited superior adsorption capacities for electron-accepting contaminants with values of 392.5 mg g −1 for norfloxacin, 249.1 mg g −1 for cytosine, and 115.3 mg g −1 for PS-COOH, while EDC showed superior adsorption capacities for electron-donating ones with values of 469.5 mg g −1 for amoxicillin, 230.5 mg g −1 for adenine, and 129.5 mg g −1 for PS-OH. Mechanistic studies, combining preferential desorption and density functional theory calculations, revealed that π-π electron donor-acceptor interactions, governed by the distinct HOMO/LUMO energies of the defects, dominate the adsorption process. Biomass-derived counterparts exhibited consistent preferential adsorption, confirming that the defect-engineering approach yields similar trends across the tested precursors. This suggests a potentially extendable strategy and offers an electronic-matching paradigm for the preferential removal of diverse ECs based on their intrinsic electronic properties.

This study evaluated Osmanthus fragrans fruit (OFF) peel as a potential source of anthocyanin-based natural colorants. Anthocyanins were extracted using acidified ethanol and purified by macroporous resin adsorption, yielding a pigment-rich extract with a recovery of 10.4 ± 0.2% from dried peel. HPLC–MS/MS analysis indicated that cyanidin-3-O-rutinoside (C3R) was the predominant anthocyanin in the extract. The molar absorptivity of C3R was experimentally determined to enable more accurate quantification of C3R-rich systems. The purified extract exhibited typical pH-dependent color behavior, maintaining a stable red coloration under acidic conditions (pH 2.0–4.0). Thermal stability experiments showed that C3R degradation was strongly influenced by temperature and pH, and the degradation behavior followed first-order kinetics. In addition, the extract displayed measurable antioxidant capacity in DPPH and FRAP assays. These results demonstrate that O. fragrans fruit peel is a promising source of C3R-rich anthocyanins with potential applications as natural colorants in acidic food systems.

A novel Ti-BTC with a mesoporous structure and uniformly dispersed Ti-OH sites was successfully synthesized. • Ti-BTC exhibits outstanding ODS activity; 99.5% of sulfur (1000 ppm) can be oxidized at 40 °C within 20 min. • The ODS activity of Ti-BTC at 40 °C reaches 52.4 mmol h −1 g −1 , exceeding that of most previously reported Ti-MOFs. • DFT results reveal that OH anchored on Ti sites react with H 2 O 2 to form Ti-OOH species that dominate ODS efficiency. • The mesoporous architecture enhances the accessibility of sulfur to Ti-OOH active sites and promotes rapid mass transfer. Desulfurization represents a pivotal process to produce ultraclean fuels, yet the design and fabrication of advanced materials to enhance desulfurization efficiency continues to pose significant challenges. Herein, a novel mesoporous titanium-based organic frameworks (Ti-BTC) was successfully synthesized via a solvothermal route. The optimized Ti-BTC exhibits outstanding oxidative desulfurization (ODS) performance, enabling the complete oxidation of various sulfur-containing compounds (1000 ppm sulfur) into the corresponding sulfones at 30 °C within 14 min or at 50 °C within 3 min with H 2 O 2 /sulfur (O/S) molar ratio of 5. Notably, even when molar ratio of O/S is reduced to 2.5, 99.5% of sulfur species are oxidized at 40 °C within 20 min. The ODS activity of Ti-BTC at 40 °C attains 52.4 mmol h −1 g −1 , surpassing most previously reported Ti-containing organic materials. Density functional theory calculation and comprehensive characterization results demonstrate that Ti-OH group anchored on vacancy Ti sites readily react with H 2 O 2 to generate peroxo-titanium intermediate, which efficiently oxidize pre-adsorbed sulfur and thus determine the overall ODS efficiency. Additionally, the mesoporous structure of Ti-BTC improves the accessibility of sulfur to in-situ-generated Ti-OOH species and facilitates rapid mass transfer, which synergistically enhances the catalytic performance.

Data-driven screening identifies melamine as optimal precursor for QbPIs. • Star-shaped topology expands HOMO-LUMO gap, introduces deep traps, and stabilizes Ag/dielectric interface. • Topological structure suppresses conduction loss and charge injection, disrupting charge-transport pathways. • QbPI-1.75 achieves 5.39 J/cm 3 at 25 °Cand 3.29 J/cm 3 at 200 °C with high efficiency. • Scalable, cost-effective design provides a platform for high-temperature polymer dielectrics beyond polyimides. The development of high-power electronics demands polymer dielectrics with high thermal stability and dielectric performance. However, most materials suffer performance degradation in harsh environments due to increased electrical conductivity. Herein, a physics-informed data-driven topology-supported precursor screening strategy was proposed to design quasi-branched polyimides (QbPIs) with enhanced energy density ( U e ) and charge-discharge efficiency ( η ) at elevated temperatures. By constructing automated screening workflow, key descriptors involving HOMO-LUMO gap ( Gap ) and dielectric constant ( ε r ) were sufficiently evaluated to form multi-parameter ranking framework, in which melamine was identified as the optimal topological center for constructing QbPIs with tunable topological ratios (0–2.5%). Notably, the resulting star-shaped topological structure effectively regulates charge transport and dielectric behavior through a cooperative mechanism. It increases the Gap , introduces deep-level traps, and stabilizes the Ag/dielectric interface, which together suppress conduction loss and charge injection, effectively disrupting long-range charge-transport pathways. The optimized QbPI-1.75 exhibited outstanding capacitive performance, delivering 5.39 J cm −3 ( U e ) with 94% ( η ) at 25 °C, and retaining 3.29 J cm −3 with 78.41% at 200 °C, far exceeding that of pure PI (1.35 J cm −3 , 87.6% η at 25 °C). This work establishes a fundamental structure-property relationship for topological PIs and provides a facile design strategy applicable to other high-temperature polymer dielectrics. A Physics-Informed Data-Driven Topology-Supported Precursor Screening Strategy screens melamine as the optimal precursor to construct star -shaped all-organic polyimide dielectric films. At 25 °C/200 °C, QbPI-1.75 exhibited breakdown strength 51.58%/32.61% higher than PI and energy densities of 5.39/3.29 J cm −3 , respectively. The star topology enhanced planar stacking to suppress thermal motion, introduced deep traps, and broadened the bandgap, synergistically blocking charge transport and raising the excitation barrier, thus overcoming material bottlenecks for high-temperature capacitive energy storage. This scalable, cost-effective approach is extendable to other polymer systems. Download: Download high-res image (107KB) Download: Download full-size image

Ratiometric biosensor overcomes challenges of single-signal biosensors. • Dual-electrode design ensures self-calibration and compensates for errors. • Achieves a low detection limit (0.004 mM) and high accuracy (>97.29%). • Higher recovery compared to the Nash assay in real food matrices. • Demonstrates excellent reproducibility in a complex food matrix. Global food safety requires reliable biosensors in complex matrices. Yet, conventional single-signal electrochemical biosensors suffer from high inter-electrode variability (RSD <12.14%) and low accuracy (<87.84%) due to common-mode signal fluctuations. This study presents a ratiometric biosensor with a dual-electrode design that enables calculation of the current ratio (I WE2 /I WE1 ) between a formaldehyde dehydrogenase-functionalized sensing electrode and an inert graphene reference to mitigate systemic fluctuations. This self-calibrating configuration reduced variability (RSD of 6.92%), improved accuracy (>97.29%), and minimized interference effects (from 7.54% to 1.52%). Spanning a linear range of 0.02–0.50 mM with a LOD of 0.004 mM, the biosensor achieved 97.22–103.87% recovery in coffee samples (RSD = 0.21%). Validation against the Nash assay showed strong correlation (R 2 = 0.995) with comparable accuracy at 0.10–0.50 mM concentrations, yet up to nine-fold higher accuracy at 0.02 mM ( p < 0.05), confirming its superior suitability for practical application in food safety monitoring.

In marine gas turbines, yttria-stabilized zirconia (YSZ) thermal barrier coatings (TBCs) experience severe degradation due to the combined presence of CMAS (CaO-MgO-Al 2 O 3 -SiO 2 ) deposits and sea salt. This study investigates the synergistic corrosion behavior of NaCl and CMAS on YSZ at 1300 °C. Results demonstrate that high-temperature Na + /Ca 2+ ion exchange elevates the local Ca/Si ratio, promoting Ca 3 ZrSi 2 O 9 formation and calcium diffusion into ZrO 2 grains. This process stabilizes the cubic phase and fundamentally shifts the corrosion pathway from standard dissolution-reprecipitation to accelerated grain boundary penetration. Corrosion tests reveal that a 50 wt% NaCl and 50 wt% CMAS mixture exhibits the highest aggressiveness, resulting in a penetration depth of 56.25 μm in 8YSZ after 10 h. These findings identify a salt-accelerated CMAS degradation mechanism driven by rapid ion exchange, offering critical insights for designing next-generation corrosion-resistant marine TBCs.

Perfluorooctanoic acid (PFOA), a representative perfluorinated compound, was widely distributed in the environment and posed significant risks to human health and the ecosystem due to its extreme chemical stability, persistence and bioaccumulative potential. Conventional coagulation-flocculation was ineffective for removing dissolved PFOA from wastewater. Herein, a branched amphoteric flocculant (BAF) was synthesized via synergistic visible light initiation using indium zinc sulfide (ZnIn 2 S 4 ) as an initiator and self-assembled tetra (4-Carboxyphenyl) porphyrin (SA-TCPP) as a photosensitizer. Its synthesis mechanisms, molecular structure, characteristics and removal mechanisms of PFOA were comprehensively investigated via characterization and molecular dynamics simulation. The ZnIn 2 S 4 and SA-TCPP synergistic initiation system generated substantial •O 2 - and •OH radicals under visible light, efficiently triggering BAF synthesis. BAF exhibited a branched structure with amide, sulfonic acid and quaternary ammonium functional groups and good thermal stability. At optimal conditions, BAF achieved 70.2% PFOA removal from simulated industrial wastewater, significantly outperforming commercial PAM. Charge neutralization, electrostatic attraction, hydrophobic interaction, hydrogen bonding and adsorption bridging collectively contributed to PFOA removal. BAF possessed the highest binding energy with PFOA. It generated larger and more settleable flocs. This study provided a promising strategy for synthesizing high-performance flocculants in an efficient way and advancing PFOA wastewater treatment.

Driven by the practical demand for industrial-scale alkaline seawater electrolysis, chloride-induced corrosion and insufficient stability at high current densities remain critical challenges. Herein, a quinary NiFeCoAlSm high-entropy alloy (HEA) was synthesized by electrodeposition, followed by selective anodic dealuminization for 60 min to obtain a chloride-resistant bifunctional HEA electrocatalyst. The partial dealuminization process regulates the electronic structure and induces a dynamic hydroxyl-rich interface. Density functional theory (DFT) calculations reveal optimized OH − adsorption and suppressed Cl − adsorption on the reconstructed surface. Sm further strengthens the metal-hydroxyl (M OH) structure and stabilizes the catalytic interface. In alkaline seawater, the catalyst delivers an oxygen evolution reaction (OER) overpotential of 356 mV at 500 mA cm −2 and operates stably for over 1000 h, while achieving stable hydrogen evolution reaction (HER) performance at 1000 mA cm −2 for over 100 h. Anion exchange membrane water electrolyzer (AEMWE) for seawater electrolysis assembled with this electrode reaches 500 mA cm −2 at 2.06 V with long-term durability. This work provides a strategy for developing efficient and corrosion-resistant catalysts for industrial-scale seawater electrolysis.

Hydroxyl-rich biomimetic particles are synthesized for bionic lotus/petal microstructures construction. • Direct-write printing of interchangeable inks creates superhydrophobic surfaces with programmable wettability • Interparticle hydrogen-bonding network and interfacial covalent bonds ensure mechanical durability. • The prepared surface enables applications such as liquid manipulation, anti−/de-icing, and patterning. Functional surfaces with controlled wettability are in high demand across fields. However, achieving such a surface property flexibly while ensuring its durability remains challenging. Here, inspired by natural organisms, we construct two types of biomimetic microstructures on target substrates, achieving low-adhesion (lotus effect) and high-adhesion (petal effect) superhydrophobic surfaces, respectively. Both microstructures are direct-write printed from dual-roughness biomimetic particles (BPs) and alkyl ketone dimer (AKD). The printing sequence determines their distinct wetting properties. The surface displays the lotus effect when AKD forms the outer layer (contact angle = 159.2°, sliding angle = 5.2°), granting it self-cleaning and anti-icing performance. The surface can resist scratching, peeling, and hundreds of severe abrasion cycles, which benefits from the high interfacial strength generated by the synergistic effect between the pre-formed interlinked network of BPs and the esterification with AKD. Crucially, when BPs are positioned on the outer layer, the surface switches to petal effect, where droplets remain pinned without sliding or falling off even when the surface is inverted (180°). By programming the printing path, this strategy is proven to exhibit significant promise in on-demand patterning and liquid manipulation.
