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.

Freshwater scarcity is a critical global challenge, driving the development of high-efficiency atmospheric water harvesting technologies. While fog collection is a sustainable solution for arid regions, conventional passive systems are often limited by poor droplet interception and slow surface renewal. This work proposes a synergistic fog-harvesting strategy combining biomimetic cactus spines (BCS) with electrostatic and aerodynamic regulation: corona charging, airflow guidance, and Laplace pressure-driven transport on cones, which shortens shedding cycles and greatly improves harvesting efficiency. Systematic experiments and fluid dynamic simulations evaluated the influence of applied voltage, wind speed, windward angle, and geometry. The BCS achieved a peak collection rate of 390 mg/min at 18 kV and a wind speed of 2 m/s, representing a substantial enhancement over passive designs. Furthermore, the performance of longitudinal and radial BCS arrays was quantitatively analyzed, leading to a modified saturation model that accounts for airflow interference between adjacent units. The results further determine the optimal working parameters and array layout, which can parametrically adjust aerodynamic airflow regulation and improve droplet transport efficiency. This multi-field coupled design offers a feasible strategy for high-efficiency electric-assisted fog harvesting under complex practical environmental conditions.

The rapid growth of electronic devices has intensified electromagnetic wave pollution. Electromagnetic wave absorption (EWA) materials provide a green solution by converting electromagnetic energy into thermal energy. Achieving high-performance EWA requires a fine balance between impedance matching and energy dissipation, demanding precise control of microstructure, interfaces, and electronic states of the materials. However, complex multiscale structures involve strongly coupled structural evolution, which reduces controllability and hinders clear structure–performance correlation. Here, a cobalt-based metal–organic framework (Co-MOF) is employed as the precursor. By regulating the contents of Ni 2 + and Fe 3 + , the structural evolution and the modulation of localized electronic states during the etching process are systematically elucidated. In addition, the in situ competitive coordination and etching-competitive coordination systems reveal the mechanistic differences between atomic-scale induced reconstruction and directional destructive reconstruction. Benefiting from synergistic regulation spanning atomic, nanoscale, and microscale levels, the obtained FeNi/C composite achieves an effective absorption bandwidth of 7.13 GHz at an ultrathin thickness of 1.97 mm. Combining DFT, COMSOL, and CST simulations, the role of etching engineering in enhancing EWA performance is elucidated from electronic, local-field, and macroscopic perspectives, providing a theoretical basis for its controllable application and the rational design of high-performance absorbers.

Fabricating high performance light-driven soft actuators remains challenging due to the viscosity limited dispersion of photothermal agents, which induces structural defects and attenuates the resulting photomechanical response. Herein, an acoustic vibration mixing (AVM) strategy is introduced to achieve an exceptionally homogeneous and optimized loading integration of polydopamine (PDA) and polypyrrole (PPy) within a polydimethylsiloxane (PDMS) matrix. This processing paradigm ensures uniform thermal distribution and robust photomechanical transduction, enabling a bilayered microrobot to execute versatile locomotion modes. Experimental results demonstrate that our actuator achieves a 100° deflection at ∼350 mW/cm 2, and the microrobot can execute terrestrial crawling (0.1 BL/s), high-speed rolling (7.5 BL/s), and Marangoni-driven aquatic gliding (0.41 BL/s). Significantly, the superior photothermal conversion efficiency empowers the robot to generate sufficient torque to overcome interfacial capillary pinning, thereby facilitating seamless bidirectional transitions between land and water. This work provides a practical fabrication paradigm for multifunctional soft robotic systems designed for complex, cross-domain environments.

Although the rational design of multifunctional lanthanide-based frameworks and exploration of their emission mechanisms have long been research hotspots in the field of material science, they remain challenging issues that are critical to the development of optical sensing tools. Herein, a novel terbium-functionalized polymer organic framework (BTH-PHEN-POF@Tb) was successfully fabricated with benzene-1,3,5-tricarbohydrazide (BTH) and 1,10-phenanthroline-2,9-dicarbaldehyde (PHEN) as the building blocks. The as-prepared POF featured abundant imine bonds and nitrogen atoms allowing efficient coordination with Tb 3+ ions, which could activate a unique target-triggered synergistic antenna effect for Tb 3+ and effectively reduce solvent-induced nonradiative quenching, leading to a distinct and adjustable fluorescence enhancement. Density functional theory (DFT) calculations and frontier molecular orbital analysis were adopted for the explanation of fluorescence enhancement mechanism. A reliable fluorescent probe was developed for dual targets sensing of typical mycotoxins, tenuazonic acid (TeA) and alternariol monomethyl ether (AME). This detection method exhibited a wide linear range, high sensitivity (limits of detection = 1.51 for TeA and 0.15 ng mL −1 for AME), and rapid response (<30 s) along with excellent probe stability. Our results created new possibilities for the fabrication and application of multifunctional lanthanide-based frameworks in analytical chemistry, particularly for the optical sensing of harmful substances.

Bridging-ligand modulation regulates stacking in metal-coordinated polymers. • Partially 3D cobalt polyphthalocyanine polymers via green ultrasonics. • Interlayer Co-N bridges stabilize framework for long cycling. : Metal-modified covalent organic polymers with planar π-conjugated structures are prone to aggregation due to strong interlayer π-π interactions, forming densely packed architectures that hinder electrolyte penetration and limit the accessibility of redox-active sites, thereby compromising their electrochemical performance as lithium-ion battery anodes. To address this issue, a bridging-ligand-driven strategy is proposed to regulate the aggregation behavior of such polymers. A cobalt polyphthalocyanine polymer (Co-TCNB) was synthesized and subsequently modified via an ultrasonic-assisted approach by introducing piperazine (PIP) as a bridging ligand. The axial coordination between PIP and cobalt centers constructs interlayer Co-N coordination bridges, which effectively weaken π-π interactions and alleviate dense stacking, while providing efficient pathways for charge transport and improving structural stability during repeated cycling. As a result, the cobalt polyphthalocyanine polymer bridged with piperazine (Co-TCNB-PIP) exhibits a significantly increased specific surface area and enhanced electrochemical performance. It delivers a reversible capacity of 850 mA·h·g −1 after 100 cycles at 200 mA·g −1 and maintains 640 mA·h·g −1 at 1000 mA·g −1 over prolonged cycling, demonstrating excellent rate capability and cycling stability, outperforming the majority of reported polymer-based anodes for lithium-ion batteries.

Bio-derived lignin nanospheres act as active interfacial regulators in W 18 O 49 . • Spectroscopy supports electronic and oxygen-vacancy-related defect modulation. • Physical-mixing controls support the importance of in situ interface formation. • W 18 O 49 /LNS shows 76.1 ± 0.8% modulation, 7 ± 1 s bleaching, and improved retention. Designing robust organic-inorganic interfaces is essential for resolving the kinetics-stability trade-off in electrochromic (EC) smart-window materials. Here, bio-derived lignin nanospheres (LNS) are used as active interfacial regulators for defect-rich W 18 O 49 nanowires. Coordination-associated interactions between LNS and W 18 O 49 are accompanied by changes in the local electronic environment and oxygen-vacancy-related defect states. The optimized W 18 O 49 /LNS film delivers an optical modulation of 76.1 ± 0.8% at 654 nm, a coloration efficiency of 31.7 ± 1.1 cm 2 C −1 , and a bleaching time of 7 ± 1 s, together with improved cycling retention. Semi-quantitative W L 3 -edge X-ray absorption analysis indicates a decrease in the estimated average W oxidation state from 3.29 to 2.89. Operando FT-IR spectroscopy and DFT calculations reveal bias-induced changes in the interfacial redox and solvation environment, while ESR and electrochemical kinetic analyses support defect modulation and an increased surface-controlled contribution. These findings establish bio-derived interfacial regulation as a promising strategy for defect-rich functional oxide nanocomposites.

To resolve the thermal-mass mismatch bottleneck in solar-driven interfacial evaporation, the study proposes a Janus interface energy-mass relay integrating high-entropy alloy oxide (HEAO) nanoparticles with a double-network hydrogel. The hydrogel acts as an enthalpy modulator, pre-activating bulk water and blocking conductive heat loss. The top HEAO layer serves as an entropy accelerator, leveraging its active sites and oxygen vacancies to rapidly shear the residual hydrogen bonds of pre-activated water. In situ XPS and DFT analyses reveal that photo-induced polarization at HEAO defects injects charge into water anti-bonding orbitals, stretching the O─H bond to 1.209 Å. Consequently, the evaporator achieves an evaporation rate of 4.02 kg m −2 h −1 under one sun illumination. This work reveals the critical role of cascaded hydration editing in breaking the theoretical limits of interfacial phase transitions.

Electrochemical CO 2 reduction must move beyond purified CO 2 to use real-world sources like flue gas or captured CO 2 . But such low-concentration feeds pose two problems: residual O 2 poisons the reaction, triggering competing oxygen reduction reaction, cutting carbon efficiency, and degrading the catalyst, while low CO 2 concentration limits mass transfer and conversion. We solve both with a kinetic molecular sieve: polyethylene glycol-coated bismuth nanoparticles (Bi@PEG). Under simulated flue gas (15% CO 2 , 5% O 2 , 80% N 2 ), Bi@PEG demonstrates record-breaking performance for CO 2 electroreduction to formate, achieving a Faradaic efficiency of 94.1 ± 0.6%, a current density of 0.91 A·cm −2 , and a single-pass CO 2 conversion of 72.5%, and maintains this performance even at 8% O 2 . Mechanism studies show the PEG layer selectively admits CO 2 (small size, quadrupole moment, strong Lewis acid, base interaction with ether oxygens; binding energy −27.4 kJ mol −1 ; diffusion barrier 0.57 eV), resulting in interfacial CO 2 enrichment. In contrast, O 2 transport is significantly impeded due to a higher diffusion barrier (0.83 eV), weak binding affinity (−3.0 kJ mol −1 ), and steric hindrance. By overcoming the dual challenges of low CO 2 concentration and oxygen interference, this work establishes “armored catalysis” as a universal approach for electrochemical CO 2 conversion using realistic, low-concentration, oxygen-containing carbon sources.
