To address the limited activity and durability of oxygen evolution reaction (OER) electrocatalysts, we present an integrated in situ strategy for constructing a three-dimensional Ni-Co dendritic electrode matrix coupled with a surface amorphous Ni-Co-Fe layered double hydroxide (LDH) catalytic layer. A Ni-Co dendritic matrix (NCDEM) with enhanced electrolyte accessibility and mass transport properties is first fabricated via jet electrodeposition, followed by the in situ hydrothermal growth of Ni-Co-Fe LDH nanosheets to construct a Ni-Co-Fe dendritic electrode (NCFDE). The introduction of NaBO₂ during the hydrothermal process regulates surface etching kinetics and the Fe³ ⁺ coordination environment, promoting uniform nanosheet growth and triggering the crystalline-to-amorphous transition of the LDH structure. The amorphous LDH layer increases the accessible active surface area, facilitates the formation of reconstructed NiOOH active species during OER, and enhances structural stability during prolonged electrochemical operation. The optimized B2-NCFDE exhibits outstanding OER performance in 1 M KOH, requiring an overpotential of only 215.34 mV to achieve 100 mA cm⁻², with a Tafel slope of 38.29 mV dec⁻¹ and stable operation at 500 mA cm⁻² for 2000 h. Furthermore, the B2-NCFDE||B2-NCFDE electrolyzer achieves 100 mA cm⁻² at a cell voltage of 1.822 V and demonstrates excellent durability for overall water splitting. This work provides a scalable strategy that integrates electrode architecture engineering with amorphous LDH regulation for efficient and durable hydrogen production.

Herein, a novel CeO 2 -supported CuO composite (denoted as CuO/CeO 2 ) is rationally designed and synthesized via a facile strategy for peroxymonosulfate (PMS) activation to degrade fluorinated antibiotic (namely florfenicol). Benefiting from the synergistic effects between CeO 2 and CuO, abundant Ce 3+ /Ce 4+ and Cu + /Cu 2+ redox couples and oxygen vacancies are formed in the composite, which can significantly accelerate interfacial charge transfer and provide sufficient active sites. The optimized CuO/CeO 2 catalyst shows exceptional catalytic performance, achieving 95.9% removal efficiency of florfenicol within 16 min, together with excellent pH adaptability, anti-interference capacity, and reusability. The mechanistic analysis reveals that PMS is firstly adsorbed on the CuO/CeO 2 surface to form CuO/CeO 2 -PMS* complexes, which then undergoes disproportionation to produce 1 O 2 . Meanwhile, O 2 •– can also transform PMS into SO 5 •‒ , which further decomposes into 1 O 2 . The nonradical pathway dominated by 1 O 2 is responsible for the degradation of florfenicol, whereas radical species and high-valent copper contribute minimally. All in all, this work provides a high-efficiency strategy for selective 1 O 2 generation in advanced oxidation processes, offering a promising approach for fluorinated antibiotic wastewater remediation.

A high-performance glucose biosensor based on a U-shaped Sagnac optical microfiber coupler (OMC) functionalized with a polyethylene glycol/chitosan–glucose oxidase (PEG/CS-GOD) composite coating is presented. The sensor is designed by integrating the Sagnac interferometer's common-mode noise rejection with the U-shaped microfiber's strong evanescent field, effectively addressing environmental instability in micro-structured optical sensors, while the multifunctional coating simultaneously provides antifouling properties, biocompatibility, and enzymatic specificity. The sensor exhibits a high refractive index sensitivity of ∼1717 nm/RIU, glucose sensitivities of 3.17 and 3.09 nm mL·mg −1 for two interference dips with excellent linearity (R 2 > 0.99), a detection limit of 0.224 mg/mL, and a response time of 13 s in simulated urine. Operational stability is demonstrated by minimal hysteresis error (<2%), approximately 81% response retention over 14 days, and satisfactory selectivity against key interferents at physiologically relevant concentrations. Consistent performance in simulated urine (3.03 nm mL·mg −1 ) and artificial serum (3.03 nm mL·mg −1 ) confirms dual-matrix detection capability. A dual-dip demodulation matrix enables real-time temperature compensation. With its balanced combination of high sensitivity, rapid response, long-term stability, and dual-matrix compatibility, this biosensor represents a promising platform for future point-of-care glucose detection.

A stable Cu-based MCOFs with outstanding laccase-mimicking nanozyme activity was synthesized. • Steady-state kinetic assays verify the superior substrate affinity and faster catalytic rate of Cu₃-TAPT COF. • A two signal-reading-mode colorimetric sensor was constructed for detection of Cr 3+ and Al 3+ . • The sensing platform can be successfully applied for real water samples. Cr 3+ and Al 3+ are toxic metal ions widely existing in environmental water, and traditional detection methods cannot meet the demand for on-site analysis. Metal covalent organic frameworks (MCOFs) are promising nanozyme candidates, which overcome the defects of conventional nanozymes by virtue of ordered structure, good stability and uniformly distributed active sites. In this study, Cu 3 -TAPT COF, a typical MCOF nanozyme with high stability and excellent laccase-mimicking activity was fabricated. Relying on the differential inhibitory effects of Cr 3+ and Al 3+ on its catalytic activity, an inhibition-based colorimetric platform was established for their separate detection. This sensing system integrates naked-eye visible color variation, quantitative absorbance signal at 510 nm, and smartphone image capture for portable on-site readout. The method validation results demonstrated that the limits of detection (LODs) were 0.30 μM for Cr 3+ and 0.22 μM for Al 3+ . The overall recoveries of all spiked groups for the two ions in three actual water samples (river water, seawater, and lake water) ranged from 93.41% to 109.8%. This work validates the great potential of laccase-mimicking MCOF nanozymes in environmental monitoring and sheds new light on the fabrication and practical exploitation of MCOF-derived nanozymes.

Revealed Al/Ni and catalyst concentration effects on polymer structure. • Clarified how propagation, chain walking, and transfer determine conversion, branching degree and molecular weight. • Developed a mechanism-inspired model for polyethylene property prediction. • Enabled inverse design for target-oriented polyethylene synthesis. Ethylene homopolymerization catalyzed by an α-diimine nickel/MAO system was investigated in toluene using a microflow platform. The effects of catalyst concentration and Al/Ni ratio on polymerization behavior and polymer structure were systematically examined. Increasing catalyst concentration enhanced the overall polymerization capability but also intensified chain-transfer effects, while the Al/Ni ratio exhibited an optimal window governed by the balance between catalyst activation and activity suppression at excessive MAO levels. Based on the chain-walking mechanism, polymer structure formation was interpreted as a dynamic competition among chain propagation, chain walking, and chain transfer, which mainly determined conversion, branching degree, and molecular weight. A mechanism-inspired apparent model was established by combining variable transformations, a third-order polynomial response surface, and Ridge regularization, enabling simultaneous prediction of key polymer properties. Furthermore, an inverse design model was developed for identifying feasible reaction conditions toward target-oriented polyethylene synthesis.

A highly efficient and environmentally friendly plasma co-melting vitrification process was developed. • The mechanisms of heavy metal fixation and migration during the plasma melting process were investigated. • Changes in the valence states and forms of various elements during the melting process were studied. Hazardous fly ash (HFA) contains large amounts of toxic heavy metals and poses significant potential risks to the environment. In this study, HFA was co-melted with hazardous bottom ash (HBA) and waste glass (WG) in a plasma system to investigate its vitrification behavior, heavy metal migration, and solidification mechanisms. The results indicate high vitrification efficiency (99.5 %) and ash solidification rate (97.1 %). The original multi-phase crystalline structure transformed into a structure dominated by an amorphous silicate network following plasma melting and rapid cooling. The surface became smoother and denser, and heavy metals were distributed uniformly, indicating enhanced physical encapsulation capacity and a more homogeneous structure. Although a considerable amount of heavy metals remained in the melt product (GP), the leaching concentrations of all detected heavy metals were significantly reduced. BCR results further indicate improved long-term stability of heavy metals. Additionally, the solidification mechanism was elucidated, involving a synergistic process of glass network encapsulation, fixation in iron-rich crystalline phases, and volatilization-redistribution-residual stabilization. As, Pb, and Cu are primarily immobilized in the glass phase, while Cr and Ni are preferentially stabilized in iron-rich spinel/ferrite-like phases; Zn and Mn exhibit dual-host behavior between the glass and crystalline phases. The results demonstrate that plasma co-melting vitrification is an effective method for the detoxification, stabilization, and resource utilization of hazardous incineration residues.

Constructing a three-channel MnO 2 nanozyme array with multi-mechanism synergy. • Revealing structure/coordination-mediated radical scavenging and electron transfer. • Discriminating flavonoid isomers sensitively down to 1 μg/mL. • Identifying adulterated samples accurately from 0 to 100%. • Demonstrating proof-of-concept Citrus differentiation on a paper-based platform. The rapid differentiation of closely related Citrus plants remains a challenge due to their highly similar physicochemical profiles. This study developed a three-channel colorimetric sensor array based on morphologically distinct MnO 2 -I/II/III nanozymes with diverse oxidase-like activity. Synergistic free radical scavenging and electron transfer during catalysis induce specific absorbance changes of TMB/oxTMB (green, yellow, and blue) at 370, 450, and 652 nm, which may be synergistically mediated by flavonoid structures and coordination interactions. The multi-mechanism three-channel design provides a highly cross-reactive dataset on a paper-based platform, enabling HCA, PCA, and 3D LDA to: (i) discriminate flavonoid isomers (1–500 μg/mL), (ii) identify adulterated samples (0–100%), and (iii) achieve 100% accuracy on an independent test set for multi-batch Citrus samples. This work presents a mechanism-distinctive MnO 2 nanozyme array, which, coupled with chemometric analysis, serves as a promising proof-of-concept platform for point-of-care screening of structurally similar flavonoids and closely related plant samples.

Oxygen-vacancy TiO 2 was prepared via inert-atmosphere annealing. • TA-Ce metal-phenolic network was deposited on micro-arc oxidized Ti. • Coatings showed enhanced near-infrared photothermal antibacterial activity. • Coatings scavenged ROS and promoted osteogenic differentiation. Titanium-based implants are widely used for bone repair but still face challenges including bacterial infection, oxidative stress, and insufficient osseointegration. In this study, a tannic acid-cerium (TA-Ce) metal-phenolic network was deposited onto an oxygen-vacancy-rich micro/nano-structured TiO 2 coating to construct a bioactive titanium surface. The coating was fabricated through micro-arc oxidation, alkali-heat treatment, inert-atmosphere annealing, and subsequent TA-Ce deposition. Oxygen vacancies enhanced near-infrared (NIR) absorption and photothermal conversion, while the TA-Ce network further improved photothermal responsiveness and antioxidant activity, under 808 nm NIR irradiation, the modified coating exhibited excellent photothermal antibacterial performance against both Staphylococcus aureus and Escherichia coli . In addition, the coexistence of Ce(Ⅲ)/Ce(Ⅳ) and phenolic groups enabled efficient reactive oxygen species scavenging, reducing extracellular and intracellular oxidative stress. In vitro studies further demonstrated favorable cytocompatibility and enhanced osteogenic differentiation, including increased alkaline phosphatase activity, collagen secretion, and mineralization. Overall, this study provides a simple and effective strategy for developing titanium implant surfaces with combined antibacterial, antioxidant, and osteogenic properties, offering new insights into multifunctional implant design.

Phenolic acid-chitosan complexes combine the antioxidant capacity of phenolic acids with the antibacterial activity of chitosan; however, their study has received limited attention due to challenges in synthesis. In this work, a selection of phenolic acids—4-hydroxybenzoic acid (HA), protocatechuic acid (PA), vanillic acid (VA), and ferulic acid (FA)—were complexed with chitosan in aqueous medium under thermal treatment. Elevated temperature markedly improved the solubility of phenolic acids, thereby enhancing complexation efficiency. XPS N 1 s analysis revealed that the balance between Free-NH₂ and ionic –NH₃ + is influenced by phenolic acid structure: phenolic hydroxyl groups promote ionic bonding, whereas methoxy groups hinder effective interaction due to hydrophobicity and steric bulk. This molecular-level programming translates into distinct macroscopic properties. The thermal stability and surface wettability of the complexes correlate with the ionic –NH₃ + content, while emulsifying performance, antioxidant capacity, antibacterial activity, and cytotoxicity are primarily governed by the intrinsic structural features of the phenolic acid ligands—such as the number of hydroxyl groups, the presence of methoxy substituents, and conjugated side chains. At concentrations relevant to antibacterial application (1.25–2.5 mg/mL), all complexes maintained >75% cell viability, indicating acceptable biocompatibility within the intended concentration range. These findings suggest a structure–property relationship in which phenolic acid substituents influence the interaction mode with chitosan and thereby affect the resulting physicochemical and biological properties. The thermal-assisted synthesis offers a simple, catalyst-free route to these multifunctional complexes, positioning them as promising candidates for applications in food preservation and related fields.

Polydimethylsiloxane (PDMS) is a promising fluorine-free hydrophobic material for proton exchange membrane fuel cell (PEMFC) microporous layers (MPLs) owing to its low surface energy, environmental compatibility, and low-temperature curing. However, weak adhesion between low-loading PDMS and carbon materials limits the structural stability, especially under hydrothermal and oxidative conditions. Here, 3-aminopropyltriethoxysilane (APTES) is used to modify carbon black and enhance the carbon-PDMS interfacial interaction. An APTES-modified 5 wt% PDMS-MPL is compared with unmodified 5 wt% PDMS-MPL and conventional 20 wt% polytetrafluoroethylene (PTFE)-MPL. Hot-water and Fenton oxidative aging, combined with microstructural, pore, hydrophobicity, X-ray photoelectron spectroscopy (XPS), and single-cell electrochemical analyses, are used to evaluate aging-induced degradation and transport evolution. APTES modification reduces the ultrasonic mass loss rate from 11.67% to 5.17%, indicating improved interfacial stability. After aging, the modified MPL maintains a more stable pore structure and hydrophobicity and shows a mass-transfer resistance of 0.194 Ω cm 2 after Fenton aging. In contrast, unmodified PDMS-MPL exhibits polymer migration, local delamination, and oxidation, whereas PTFE-MPL retains a relatively stable pore structure but shows stronger high-current mass-transport limitations. These results demonstrate that APTES interfacial modification improves the structural stability and aging resistance of low-loading fluorine-free PDMS-based MPLs.

Mulberry,
a traditional medicinal and edible plant rich in polysaccharides
and flavonoids, has potential in regulating emotional behaviors. This
study compared emulsified mulberry extract (EME) and aqueous mulberry
extract (AME) on anxiety- and depression-like behaviors in male C57BL/6J
mice exposed to chronic unpredictable mild stress (CUMS), and explored
the underlying mechanisms of EME. EME alleviated anxiety- and depression-like
behaviors more effectively than AME, with superior colloidal stability
and dispersion. Metabolomic profiling revealed higher relative abundances
of carbohydrates, eicosanoids, and flavonoids in EME. EME remodeled
the gut microbiota–short-chain fatty acid (SCFA) axis, enhanced
colonic barrier integrity, reduced serum lipopolysaccharide and proinflammatory
cytokines, decreased stress hormone levels, elevated 5-hydroxytryptamine,
and suppressed hippocampal glial activation while preserving neuronal
integrity. Correlation analyses linked gut microbiota, SCFAs, hypothalamic-pituitary-adrenal
axis activity, and behavioral phenotypes. These findings indicate
that emulsification enhances the bioactivity of whole-component mulberry
extracts, supporting their potential as natural food-based interventions
for emotional disorders.
