Magnetic alloy powders combining corrosion resistance and microwave absorption capability are highly desirable for harsh-environment applications; however, the coupling between corrosion evolution and electromagnetic performance remains poorly understood. Herein, the corrosion behavior, microstructural evolution, and microwave absorption performance of FeSiCr powders were systematically investigated during a 30-day exposure in an acidic saline (5 wt% NaCl, pH = 3). The results reveal a three-stage corrosion process driven by selective oxidation. In Stage 1, preferential oxidation of Cr and Si forms a protective oxide layer that suppresses Fe corrosion and improves impedance matching, enabling D12-FeSiCr to achieve an optimal RL min of −51.75 dB and a maximum RCS reduction of 28.1 dB m 2 , outperforming the pristine D0-FeSiCr sample (−48.82 dB). In Stage 2, depletion of surface Cr and Si accelerates Fe oxidation and corrosion kinetics, while the porous iron oxides weaken magnetic properties but introduce additional dielectric polarization loss, leading to only slight deterioration in microwave absorption performance. In Stage 3, a stable corrosion layer slows further corrosion; however, reduced magnetic loss and degraded impedance matching ultimately results in inferior absorption performance. This work reveals the intrinsic coupling between corrosion behavior and electromagnetic properties, providing fundamental insights for environmentally robust microwave absorber design.

In response to the need for efficient elimination of methylene blue (MB) from dye-containing wastewater, a Mo, N-co-doped carbon quantum dot-modified BiVO 4 (5% Mo, N-CQDs/BiVO 4 ) composite photocatalyst was developed. Pristine BiVO 4 suffers from rapid charge carrier recombination and limited visible-light utilization. Introduction of Mo, N-CQDs establishes a synergistic enhancement mechanism: (1) Mo, N-CQDs act as electron mediators, improving interfacial charge separation and migration, as evidenced by reduced charge transfer resistance. Mo doping introduces impurity energy levels that trap electrons and retard recombination, while nitrogen doping enhances electron tunneling and reduces interfacial resistance. (2) UV-Vis DRS confirms bandgap narrowing and enhanced visible-light absorption. (3) Photoelectrochemical analysis reveals significantly enhanced photocurrent response and reduced charge transfer resistance, confirming improved charge separation efficiency. Under visible light, the composite achieved a degradation rate constant of 0.04089 min −1 toward MB, a 3.31-fold enhancement over pure BiVO 4 , with >95% removal within 80 min. Radical trapping identified superoxide radicals (·O 2 − ) and holes (h + ) as the predominant active species, with h + contributing ∼62% of the activity. The catalyst retained 88.65% of its initial efficiency after four cycles, demonstrating good stability. This study provides a viable charge-regulation strategy using multi-element co-doped carbon quantum dots for semiconductor modification, highlighting its potential in dye wastewater treatment.

A g-C 3 N 4 /Bi 2 MoO 6 /Bi 2 WO 6 ternary heterojunction was constructed via simple mechanical grinding and thermal treatment. • GBMW follows a dual Z -scheme charge-transfer pathway, preserving strong redox capability for enhanced photocatalysis. • U(VI) acts as an electron acceptor to promote charge separation and improve photocatalytic performance. Due to the difficulty of conventional photocatalytic systems in simultaneously achieving strong oxidation and reduction processes, the treatment of wastewater containing coexisting uranium and organic pollutants remains a critical challenge in the field of photocatalysis. Herein, a novel g-C 3 N 4 /Bi 2 MoO 6 /Bi 2 WO 6 (GBMW) ternary photocatalyst with a dual Z -scheme heterojunction architecture was rationally constructed for the removal of U(VI) and tetracycline (TC) under visible-light irradiation. The dual Z-scheme heterojunction extends the visible-light response range and accelerates interfacial charge transfer, while preserving strong redox potentials. Within 100 min, GBMW achieves a U(VI) reduction efficiency of 91.6% and a TC degradation efficiency of 97.6%, with corresponding k obs values of 0.02332 and 0.03664 min −1 , respectively, which are significantly superior to those of BiMO, BiWO, GCN and GBW. Notably, U(VI) can act as an efficient electron acceptor to promote the separation of electrons and holes in GBMW, which significantly facilitates the degradation of TC. Moreover, GBMW demonstrates excellent stability and anti-interference performance in various real water matrices. This work not only provides a feasible strategy for constructing high-efficiency dual Z -scheme heterojunctions photocatalysts, but also offers an effective solution for treating complex wastewater containing coexisting organic pollutants and radioactive contaminants.

Herein, a novel chitosan-based magnetic bio-sorbent (M-Cs-BD@TBB) was synthesized through grafting chitosan with benzaldehyde (BD) and then crosslinking with 1,3,5-tris(bromomethyl)benzene (TBB) before modification with Fe 3 O 4 . Owing to the presence of multiple functional groups (-OH, -C=N, O , benzene ring), high porosity, and excellent wettability, M-Cs-BD@TBB demonstrated good adsorption performance for benzoylurea insecticides (BUs). Hydrogen bonding, π-π stacking, halogen bonding, and pore-filling were proved to be the potential adsorption mechanism. Moreover, the adsorption process of M-Cs-BD@TBB for BUs followed the Langmuir model and the pseudo-second-order kinetics model, indicating monolayer adsorption predominantly governed by chemical adsorption. Furthermore, M-Cs-BD@TBB exhibited remarkable utilization potentiality thanks to its outstanding preparation reproducibility, stability, and repeatability. Then, this reliable and innovative bio-sorbent coupled with high performance liquid-phase chromatography provided an attractive method for effectively trapping and detecting trace levels of BUs in food samples.

Precise regulation of endogenous reactive oxygen species (ROS) is critical for maintaining physiological homeostasis, while dysregulated ROS levels are implicated in diverse pathologies. In vivo monitoring of this key signaling molecule represents an urgent priority, yet poses significant challenges due to the limitations of conventional ROS probes reliant on ultraviolet-visible excitation for high-fidelity biological imaging. To address this constraint, we engineered a luminescent nanoprobe by conjugating IR783 with upconversion nanoparticles (UCNPs), enabling H 2 O 2 detection via upconversion luminescence. The detection mechanism involves ROS-triggered cleavage of IR783, inducing nanostructure disassembly and subsequent restoration of upconversion luminescence. This design yields a concentration-dependent luminescence turn-on response, where upconversion luminescence intensity escalates proportionally with H 2 O 2 levels. The UCNPs-IR783 nanoprobe exhibits minimal cross-reactivity with biomolecules and low cytotoxicity, enabling effective visualization of both intrinsic and extrinsic reactive oxygen species within Hepa1-6 and RAW264.7 cellular models. Furthermore, investigations in murine subjects validate its applicability for ROS detection specifically within the tumor microenvironment.

Mixed-matrix membranes (MMMs) offer a promising route to efficient gas separation by synergizing the superior transport properties and stability of porous fillers with the scalability of polymeric matrix. However, fabricating ultrathin, high-loading MMMs remains a significant challenge, as conventional solution processing inevitably leads to filler agglomeration. Here, we report a decoupled assembly strategy to fabricate ultrathin, highly loaded MMMs by separating membrane formation into two distinct stages: filler monolayer assembly and subsequent matrix electropolymerization. This approach enables the formation of ordered, close-packed nanoparticle monolayers, facilitating the attainment of ultra-high filler loadings (>60 wt%) in the final membrane. Using metal-organic frameworks (MOF-801 and MOF-808) as fillers and a conjugated microporous polymer (CMP) as the matrix, we constructed robust MMMs with thicknesses of 390 nm and 550 nm, respectively. Applied to CO 2 /CH 4 separation, the resulting membranes exhibited a 12-fold increase in CO 2 permeance (from 26 to 313 GPU) and a 120% enhancement in selectivity compared to the pristine polymer matrix.

Achieving lightweight microwave absorbers with strong attenuation, broad bandwidth and small matching thickness remains challenging for electromagnetic protection. Hollow ceramic microspheres (HCMs) are attractive lightweight supports owing to their low density and hollow structure, but their limited intrinsic dielectric loss and negligible magnetic response restrict microwave attenuation. Although binary hollow microsphere/ferrite or hollow microsphere/conductive-polymer systems can improve electromagnetic response, simultaneously balancing attenuation and impedance matching remains difficult. Herein, hierarchical HCM@NZF@PANI ternary absorbers were constructed by sequentially anchoring Ni–Zn ferrite (NZF) particles and depositing polyaniline (PANI) onto aminated HCMs. In this architecture, HCMs act as lightweight frameworks and scattering centers, NZF introduces auxiliary magnetic response and magnetic/dielectric interfaces, and PANI serves as a dielectric regulation layer. Structural characterizations confirmed rough core–shell microspheres with abundant multiphase interfaces. Increasing PANI content enhanced complex permittivity, dielectric loss tangent and attenuation constant while maintaining favorable impedance matching. HNP-60 delivered the optimal absorption performance, with a minimum reflection loss of −47.55 dB at 16.24 GHz at 1.5 mm and an effective absorption bandwidth of 5.52 GHz covering 11.76–17.28 GHz at 1.7 mm. The enhanced performance arises from multiple scattering, PANI-derived conductive loss, dipole polarization, Maxwell–Wagner interfacial polarization and auxiliary magnetic response. Radar cross-section simulation further verified the echo suppression capability of the coating, demonstrating a feasible interfacial regulation strategy for lightweight, thin and broadband ceramic-based absorbers.

HRP was covalently immobilized on MAF to form a biocomposite with high activity and fluorescence. • HRP@MAF exhibited a remarkable fluorescence quantum yield of 97.77%. • HRP@MAF showed superior substrate affinity with a Km value 25-fold lower than HRP. • A dual-mode colorimetric/ratiometric fluorescent sensor was developed for histamine. Integrating strong fluorescence and efficient biocatalysis within a single metal-organic framework (MOF) is attractive for advanced optical sensing. Herein, a highly emissive metal-organic framework (denoted as MAF) was constructed using ligands with aggregation-induced emission (AIE) properties, followed by horseradish peroxidase (HRP) immobilization to yield HRP@MAF with high catalytic activity and strong fluorescence. The resulting HRP@MAF exhibited a fluorescence quantum yield of 97.77%. Benefiting from the high surface area and porous structure of MAF, HRP@MAF showed markedly improved stability and substrate affinity toward 3,3′,5,5′-tetramethylbenzidine (TMB), with a K m value 25-fold lower than that of free HRP. Based on its catalytic and optical properties, a colorimetric/ratiometric fluorescence sensor was developed for histamine detection with detection limits of 1.71 μM and 0.56 μM, respectively. In addition, smartphone-integrated on-site detection was achieved with linear ranges of 10–1000 μM for the colorimetric mode and 1–1000 μM for the ratiometric fluorescence mode. This work establishes an effective strategy for constructing multifunctional sensing platforms by coupling AIEgens derived highly emissive MOFs with immobilized enzymes.

Carbon aerogels are highly promising lightweight microwave absorbers, yet their intrinsic brittleness and disordered pore structures significantly limit both mechanical reliability and electromagnetic (EM) performance. Here, a flexible honeycomb-like anisotropic hybrid carbon aerogel (CFMT), modified with MoS 2 /FeS 2 nanoparticles and toughened by a polyurethane network, is developed to overcome these limitations. Benefiting from the aligned quasi-periodic pore architecture, CFMT exhibits a distinct anisotropic electromagnetic response. When incident waves propagate parallel to the honeycomb channels, strong dielectric relaxation is induced, and localized electromagnetic resonance (LEMR) is generated within the pore structure, enabling efficient capture and dissipation of centimeter-wavelength electromagnetic energy. Consequently, the CFMT aerogel delivers an ultrawide effective absorption bandwidth of 11.84 GHz, accompanied by a minimum reflection loss of −50 dB. In addition to excellent microwave absorption, the aerogel also demonstrates robust mechanical flexibility and superior infrared stealth capability. This work explicitly elucidates the mechanism by which quasi-periodic porous structures enhance microwave absorption performance, providing a highly effective design paradigm for next-generation, multifunctional, and flexible electromagnetic wave absorbers.

Hydrophobic herbicides often suffer from poor solubility and low bioavailability in crop protection applications, which hinders the sufficient uptake of active ingredients by target weeds and severely limits their effectiveness in safeguarding crop growth. To enhance the delivery efficiency and targeting capability of such herbicides, this study developed a pH-responsive amphiphilic polymer nanocarrier using the natural product kojic acid and triethylene glycol divinyl ether as raw materials for loading diuron. This carrier can self-assemble in aqueous media to form stable core-shell nanoparticles with a critical micelle concentration of 6.92 × 10 −3 mg/mL and an average particle size of 181.4 nm after drug loading. In a simulated acidic rhizosphere environment of Echinochloa crus-galli , the drug-loaded nanoparticles exhibited distinct pH-responsive release behavior while maintaining good physical stability. Biological experiments further confirmed that this delivery system significantly enhances the herbicidal activity of diuron against Echinochloa crus-galli , providing new insights and a material foundation for the development of efficient and intelligent herbicide delivery systems.

The rational design of interfacial active sites is crucial for enhancing the activity and durability of Pd-based electrocatalysts for ethanol oxidation reaction (EOR). Herein, an ultrathin PdNi metallene (PdNiene) with unique asymmetric Pd─O─Bi oxo-bridge sites (PdNi-O-Biene) is synthesized via a multi-step hydrothermal method. The ultrathin 2D nanosheet structure of the metallene enables abundant exposure of Pd active sites. Notably, Ni incorporation facilitates OH * adsorption/formation and thereby promotes the oxidative removal of CO * intermediates, while the Bi-induced asymmetric oxo-bridge interface triggers interfacial charge redistribution around Pd active centers, which further facilitates CO * desorption/oxidative removal and efficient C─C bond cleavage, thus favoring the C1 reaction pathway. As a result, the optimized PdNi-O-Biene demonstrates exceptional mass activity (8.42 A mg Pd −1 ) and specific activity (28.09 mA cm ECSA −2 ) for EOR in alkaline electrolyte, representing improvements of 5.5 and 3.7 times over commercial Pd nanoparticles (Pd NPs), respectively. This work not only provides an effective strategy for the synthesis of high-performance EOR electrocatalysts but also highlights the potential of atomic-scale interface engineering for alcohol oxidation reactions.

It remains a great challenge to optimize electron and phonon scattering for high thermoelectric performance in semiconductor materials using traditional composition or phase design methods. Herein, we demonstrate an effective strategy using mesoporous structures to address this challenge. The mesoporous Bi 2 Se 3 thin films with uniform pores and a semiconductor framework were prepared by using amphiphilic block copolymers as structure-directing agents, electric field-driven micellar template interfacial self-assembly, and electrochemical deposition. The porosity, pore size, and thickness can be controlled through tuning parameters such as deposition potential, deposition time, molecular weight of block copolymer, and solution concentration. The resultant multilevel interfacial structures optimized the electron scattering potential and effectively scatter the phonons. This leads to improved Seebeck coefficient and power factor by 268.8% and 730.5% simultaneously, when compared with nonporous samples. The highest power factor can reach 22.36 µW·cm −1 ·K −2 that is higher than most reported values. Furthermore, this novel preparation method has succeeded in other thermoelectric semiconductors such as Bi 2 Te 0.5 Se 2.5 and Cu 3 Se 2 . Therefore, this work provides new insights into the design of novel mesoporous semiconductor thin films as high-performance thermoelectric materials for thermal management in computer chips and other applications.
