Motivated by gas-accessible thin liquid films in lung alveoli, we develop gas marble-film reactors in which particle-stabilized bubbles confine an ultrathin freestanding liquid film within a jammed solid shell. Hexagonal PET (poly(ethylene terephthalate)) plates, in addition to conventional spherical particles, generate faceted gas marbles with planar film regions that improve optical access. We quantify the pressure limits of microsphere- and plate-stabilized shells during inflation and deflation, and describe their response using a capillary–granular framework. In this framework, inflation rupture is governed by capillary breakthrough at particle-defined throats, whereas deflation collapse reflects the combined resistance of capillarity and interparticle jamming. The mechanically defined films then serve as gas-accessible interfacial reactors in two proof-of-concept demonstrations. In a Tollens reaction, aerosolized glucose delivery through the external gas phase localizes silver reduction to liquid-wetted regions of the particle shell, producing spatially patterned silver-deposited microspheres. In biological assays, plate-stabilized shells provide flat observation windows for monitoring aerobic E. coli growth and its inhibition by levofloxacin. These results establish gas marbles as programmable colloidal film reactors whose structure, pressure stability, and interfacial function can be coupled through particle geometry and capillary jamming.

Replacing α -hydroxyl group with an α , β -unsaturated group markedly enhanced the decomposition reactivity of dimer. • α , β -Unsaturated group promoted C α ─C β bond cleavage, while α -hydroxyl group led to β -O-4 bond cleavage. • α , β -Unsaturated group accelerated reaction rate ∼14-fold at 120 °C. • Dehydration of α -hydroxyl group into α , β -unsaturated group facilitated lignin depolymerization. Lignin is a promising feedstock for the production of monomeric aromatics, which can be further upgraded into valuable chemicals or fuel hydrocarbons. In this work, the effect of the α , β -unsaturated group on the conversion of lignin and its β -O-4 model dimers into monomeric aromatics was investigated. The results showed that replacing the native α -hydroxyl group with an α , β -unsaturated group markedly enhanced the decomposition reactivity of the dimer. Specifically, the α , β -unsaturated group promoted C α ─C β bond cleavage, whereas the native α -hydroxyl group led to β -O-4 bond cleavage. This significant enhancement in reactivity was consistent across varied reaction conditions and enabled near-quantitative yields of monomeric aromatics from the dimer containing the α , β -unsaturated group. Kinetic analyses indicated apparent first-order kinetic behavior for both dimers, showing that the α , β -unsaturated group accelerated the reaction rate by a factor of approximately 14 at 120 °C. Moreover, an α , β -unsaturated group generated in situ via dehydration of the α -hydroxyl group during pretreatment effectively facilitated lignin depolymerization. This work outlines a promising approach for developing efficient lignin depolymerization technologies targeting monomeric aromatics.

The dielectric–magnetic synergy and interfacial engineering is an important methodology to boost electromagnetic wave absorption performance. We herein propose a novel “coating-ion exchange etching-high temperature carbonization” process to synthesize yolk–shell zinc oxide/carbon@air@cobalt-nickel alloy (ZnO/C@air@CoNi) nanocages by taking advantages of dielectric–magnetic synergy and interfacial effect. The bimetallic core–shell ZIF-8@ZIF-67 precursor is employed as the structural template while Ni(NO₃)₂·6H₂O as an etchant to ensure controlled ion-exchange etching. The resulting dielectric zinc oxide/carbon (ZnO/C) core promotes interfacial polarization and dipole reorientation losses, while the CoNi shell enhances conductive loss and magnetic loss. Thanks to the dielectric–magnetic synergy and interfacial effect, the ZnO/C@air@CoNi nanocomposite exhibits outstanding electromagnetic wave absorption performance, achieving a maximum reflection loss of −72.28 dB and an effective absorption bandwidth of 5.28 GHz (12.40 −17.68 GHz) at a low filler loading of 20 wt%. This work provides new ideas to design absorbers by leveraging the structural versatility of MOF-derived precursors.

A MIP/AuNPs/GCE electrode was constructed for simultaneous detection of CAP and MNZ. • The sensor shows a wide linear range (50–1500 μM) and low LODs of 1.70 and 2.09 μM. • Wavelet transform expands the feature dimensions of the DPV signals to enhance model prediction accuracy. • TPE-optimized XGBoost realizes accurate and robust dual-analyte concentration prediction. • The method achieves satisfactory recoveries in milk, fish, and egg real samples. Food safety concerns have increased the demand for reliable simultaneous detection of chloramphenicol (CAP) and metronidazole (MNZ), as these antibiotics are strictly regulated due to their potential health risks. However, the presence of aromatic nitro groups in both compounds poses a challenge for their simultaneous detection. In this study, an electrochemical sensor integrating electrodeposited gold nanoparticles (AuNPs) with a dual-template molecularly imprinted polymer (MIP) film was developed to achieve selective recognition and signal enhancement for both analytes. However, competitive adsorption at active sites in multi-component systems leads to nonlinear signal responses, rendering traditional linear calibration ineffective. To overcome this limitation, differential pulse voltammetry (DPV) signals were transformed into two-dimensional wavelet spectrograms, from which quantitative image features were extracted, and the necessity and robustness of these features were verified using SHAP analysis. An XGBoost regression model optimized via a Tree-structured Parzen Estimator (TPE) was subsequently constructed, yielding significantly improved predictive performance. The sensor exhibited a wide linear range for both CAP and MNZ (50–1500 μM) and low detection limits (1.70 μM and 2.09 μM, respectively). Satisfactory recoveries (89.37–107.31%) were obtained in spiked milk and fish samples. The proposed TPE-XGBoost-assisted dual-template molecular sensor provides a robust and generalizable strategy for rapid and accurate multi-residue detection in complex food matrices.

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.
