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.

The solution-based fabrication of perovskite solar cells (PSCs) typically relies on high-purity materials, the cost of which limits commercial scalability. Here, we report an efficient strategy for directly synthesizing FAPbI 3 -based perovskite microcrystals (MCs) from industrial-grade precursors using formic acid (HCOOH) as a multifunctional additive and antisolvent in a synergistic process combining inverse temperature crystallization (ITC) and antisolvent-assisted precipitation. In situ grazing-incidence wide-angle X-ray scattering (GIWAXS) analysis reveals that formate anions (HCOO − ) coordinate with Pb 2+ to regulate crystallization, passivate structural defects, and promote the direct formation of α-FAPbI 3 . An optimal HCOOH concentration (40%–60% v/v) was identified, achieving a high microcrystalline yield of 92.83% and effectively suppressing the formation of δ-FAPbI 3 . However, concentrations exceeding this range (>80% v/v) disrupt the precursor stoichiometry, leading to PbI 2 impurity segregation. Thin films fabricated using the optimized microcrystals exhibited improved morphological uniformity, enhanced crystallinity, reduced nonradiative recombination losses, and extended charge carrier lifetimes. As a result, inverted-structure PSCs based on these MCs achieve a champion power conversion efficiency of 25.24% (0.07 cm 2 ). This work presents a cost-effective and scalable route for producing high-quality perovskite materials and provides mechanistic insights into the dual functionality of HCOOH, offering valuable guidance for the advancement of low-cost, high-performance perovskite photovoltaic technologies. Graphical Formic acid serves a dual function as both an additive and antisolvent, directing the direct crystallization of α phase perovskite microcrystals from low purity industrial precursors. This one-step strategy achieves a 92.83% yield, simultaneous defect passivation, and a champion solar cell efficiency of 25.24%.

Sulfur dioxide (SO 2 ) and its derivative bisulfite (HSO 3 − ) are widely utilized in food processing but pose potential health hazards at excessive concentrations, highlighting the critical need for rapid and sensitive detection methods for sulfite/bisulfite species. Herein, we report the synthesis of a novel fluorescent probe TPA-OH featuring a donor–π–acceptor (D–π–A) architecture, with triphenylamine (TPA) as the electron-donating unit and 7-hydroxy-1-indanone as the electron-withdrawing moiety. The conjugated C═C double bond enables intramolecular charge transfer (ICT) within the probe. Upon interaction with sulfite/bisulfite species, presumably through nucleophilic addition to the C═C bond, the π-conjugated system is disrupted, resulting in a pronounced fluorescence enhancement accompanied by a distinct blue shift. Under optimized conditions, TPA-OH exhibited a low detection limit of 0.053 µM based on repeated calibration experiments and a broad linear range of 5.0 × 10 − 8 ∼1.0 × 10 − 5 M, along with good stability and strong anti-interference capability toward sulfite/bisulfite detection. This probe was successfully applied for HSO 3 − quantification in real samples and fluorescence imaging of exogenously added HSO 3 − in HepG-2 cells under controlled experimental conditions. Its favorable cytocompatibility supports its use for fluorescence imaging of exogenous sulfite/bisulfite species in living cells under the current experimental conditions. Graphical A novel D–π–A fluorescent probe (TPA-OH) was designed using a triphenylamine donor. The probe detects HSO 3 − via a specific nucleophilic addition disrupting π-conjugation. TPA-OH exhibits an ultralow detection limit of 0.05 nM and broad linear range. Successfully applied for HSO 3 − detection in foods and fluorescence imaging in living cells.

Gastrodia elata Bl. (GE), a representative medicine–food homology material, requires appropriate processing prior to food application to meet established medicinal quality standards. However, the effects of different traditional processing methods on its quality attributes remain insufficiently elucidated. In this study, three representative processing methods, steaming, moistening, and bran-frying, were systematically compared to evaluate their impact on the structural, compositional, and flavor characteristics of GE. The results demonstrated that processing markedly altered both the physical structure and chemical composition of GE. Moistening caused minimal disruption to the native tissue architecture and largely preserved the free-water distribution pattern. Notably, gastrodin and p-hydroxybenzyl alcohol contents reached 0.38% and 4.16%, respectively, the highest among all treatments, while the overall flavor profile remained closest to that of fresh GE. In contrast, bran-frying induced pronounced dehydration and structural densification, with volatile compounds and differential metabolites accounting for 72.83% and 41.01%, respectively. This treatment also exhibited elevated levels of total phenolics, flavonoids, and protein. Steaming, by comparison, promoted starch gelatinization and water redistribution, shifting the flavor profile from a delicate herbal note toward enhanced umami, floral, and mildly roasted characteristics. Overall, these findings reveal that processing-induced structural remodeling and changes in water state play critical roles in regulating the quality attributes of GE. By integrating structural characterization, water-state analysis, and multi-omics data, this study provides a systematic understanding of the formation of GE quality attributes under different processing methods, offering a theoretical basis for quality control and process optimization.

A facile one-pot strategy synthesizes porous B-NiCo-LDH/Ti 3 C 2 2D/2D heterostructures. • B doping tunes electronic structure and strengthens NiCo-LDH/Ti 3 C 2 interfacial bond. • Composite shows enlarged surface area and optimal porous structure for ion transport. • This work offers a universal strategy for designing doped 2D heterostructures. MXenes and layered double hydroxides (LDHs) emerge as advanced electrode candidates for high-performance supercapacitors. Nevertheless, pure Ti 3 C 2 or LDH suffers from either self-stacking or low electronic conductivity and instability. In this work, porous B-doped NiCo-LDH (B-NiCo-LDH) anchored on Ti 3 C 2 nanosheets has been designed and fabricated via a one-pot co-precipitation reaction. Element doping, composite fabrication and structural regulation are realized simultaneously via a simple one-step synthetic strategy. The obtained 2D/2D B-NiCo-LDH/Ti 3 C 2 heterostructures combine the advantages of LDH, Ti 3 C 2 , element doping and porous structure. Boron incorporation diminishes interfacial binding energy in the B-NiCo-LDH/Ti 3 C 2 system, expedites electron movement across interfaces, and ameliorates the composite’s electrical conductivity. The optimal B-NiCo-LDH/Ti 3 C 2 -20 delivers a specific capacitance of 1581.66 F g −1 at 1.0 A g −1 , a rate capability with 82.73% capacitance retention at 20 A g −1 , and a cycling stability of 77.55% after 5000 cycles. An aqueous battery-type hybrid asymmetric supercapacitor (HASC, B-NiCo-LDH/Ti 3 C 2 -20//Bi 2 O 3 /Ti 3 C 2 ) exhibits an energy density of 87.28 Wh kg −1 at a power density of 753.86 W kg −1 . This work provides a feasible strategy for improving energy storage performance via the design of element-doped 2D heterostructures.

Photocatalytic disinfection is a low-cost, efficient, and sustainable technology, particularly suitable for underdeveloped regions. However, its practical application is limited by severe electron-hole recombination, which reduces photocatalytic efficiency, and the poor reusability of powdered catalysts. Although heterojunction design and catalyst immobilization have been employed to address carrier recombination and recyclability, respectively, these two bottlenecks have not yet been simultaneously resolved. In this study, a reusable three-dimensional core-shell array architecture was constructed on a carbon fiber support based on catalyst morphology and disinfection mechanism considerations. The resulting core-shell heterostructure exhibited inactivation indices 2.2 and 2.5 times higher than those of the P25-loaded film and the pristine TiO2 array structure, respectively.

To address the persistent challenge of membrane wetting during oil-gas separation in transformer condition monitoring, an omniphobic composite membrane was developed to facilitate the reliable online detection of dissolved gases. An F-CNTs/Teflon AF/PVDF composite membrane, featuring a loofah-like hierarchical structure and omniphobic properties, was fabricated via spraying-deposition strategy on the polyvinylidene fluoride (PVDF) substrate. The morphology, surface chemical composition, wettability and stability of the F-CNTs/Teflon AF/PVDF composite membrane were systematically characterized. Subsequently, the oil-gas separation performance of the composite membrane was evaluated using standard transformer oil containing dissolved gases as the feed solution. The results indicated that fluorinated carbon nanotubes (F-CNTs) were successfully modified onto the membrane surface, creating a re-entrant morphology composed of an intersecting nanotube network that mimics the hierarchical architecture of a loofah. The F-CNTs/Teflon AF/PVDF composite membrane exhibited exceptional omniphobicity, achieving contact angles of 168.2 ± 1.5° and 127.5 ± 1.0° towards DI water and mineral insulating oil, respectively. Additionally, the loofah-inspired composite membrane demonstrated robust thermal and ultrasonic stability. In oil-gas separation tests, the omniphobic membrane displayed a rapid response and high efficiency for dissolved gas extraction, achieving dynamic equilibrium within 64 min. Furthermore, the modification improved permeation efficiency by 25.6%. These results suggest that the developed omniphobic membrane is a promising alternative for oil-gas separation in the condition monitoring of oil-filled electrical equipment.
