Na₂CO₃-NaCl eutectic molten salt is used to enhance Ni/CC catalyst for CMD. • 97.6% CH₄ conversion is obtained over 20 h under a counter-current gas flow system. • High and stable activity arises from a triple synergistic effect of the salt system. • The molten salt achieves >99% recovery via simple water washing and evaporation. • Besides H 2 , carbon products are graphitic spheres and thin graphitic sheets. Catalytic methane decomposition (CMD) is a promising route for low-CO ₓ hydrogen production, but conventional solid catalysts suffer from rapid deactivation due to carbon encapsulation and metal sintering. Herein, we develop a low-cost, robust gas-liquid-solid triphasic system by integrating a Ni/coal-char catalyst with a Na₂CO₃-NaCl eutectic molten salt (with an optimized mass ratio of 6:4 and counter-current operation). At 850 °C, this system achieves a stable methane conversion of 97.6% over 20 h, with no obvious deactivation. The exceptional performance originates from a triple synergistic effect of the eutectic salt: (i) mass transfer enhancement via counter-current operation, (ii) interface protection that suppresses Ni sintering and directs carbon growth toward value-added graphitic structures, and (iii) potential electronic modulation via Ni 2+ -CO₃ 2− coordination that facilitates CH 4 activation and conversion. Furthermore, the molten salt can be recovered almost completely (>99%, as determined by titration), with 94.1% methane conversion maintained after five cycles. This work provides a promising strategy toward industrial hydrogen production and deepens the mechanistic understanding of physical-chemical synergy in molten salt-mediated CMD systems.

A bioinspired self-pumping Janus paper electrode was developed for wet-skin ECG. • Asymmetric wettability (127°/28°) enabled directional liquid transport within 10 s. • The interface combined wet adhesion, high breathability, and conductive stability. • Stable ECG signals were acquired during sweating, walking, and brief submersion. • The platform offers active liquid management for wet-stable epidermal bioelectronics. Wet epidermal electrocardiogram (ECG) interfaces commonly suffer from the coupled deterioration of adhesion, breathability, and signal fidelity under sweating and motion. Here, we report a self-pumping Janus paper electrode comprising a skin-contacting hydrophobic polydimethylsiloxane (PDMS)-based adhesive layer, a mechanically compliant interlayer, and an outer hydrophilic carbon-nanotube (CNT)-doped porous paper layer. A coupled wettability and pore-size gradient promotes directional drainage of interfacial liquid away from the skin–electrode contact. The interface exhibits asymmetric wettability (127°/28°), directional liquid transport within 10 s, measurable water uptake, adhesion on moist skin, water-vapor permeability, and stable ECG acquisition during sweating and walking. Distinct from Janus liquid-transport materials or wet-adhesive ECG interfaces that primarily address either directional wetting or adhesion, this work presents a coupled-gradient capillary-rectification strategy in which wettability and pore-size gradients generate an asymmetric capillary-pressure landscape. The paper-based interface integrates wet adhesion, water-vapor permeability, liquid management, and ECG signal acquisition, providing a strategy for stable wet-skin ECG monitoring under the tested conditions.

Managing phosphoric acid (PA) distribution within the catalyst layers is a critical challenge for the development of high-performance high-temperature proton exchange membrane fuel cells (HT-PEMFCs). This work introduces a novel strategy using hexamethylenediamine tetra(methylenephosphonic acid) (HDTMPA) as a functional additive in the cathode to precisely regulate the local PA environment. HDTMPA performs a dual function: its strong hydrogen-bonding interactions with PA effectively anchor the acid, which prevents the excessive flooding and poisoning of Pt catalyst sites, while its electron-rich nitrogen atoms help establish a robust proton-conduction network. Consequently, a membrane electrode assembly (MEA) with an HDTMPA-modified cathode (0.5 mgPt cm −2 ) achieves a peak power density of 715 mW cm −2 at 150 °C, a 42% enhancement over the unmodified baseline (503 mW cm −2 ). Furthermore, the modified MEA demonstrates exceptional durability, exhibiting only a 5.0% performance decay after an accelerated durability test of 10,000 cycles, compared to a 17.5% decay for the control. In-situ electrochemical analysis confirms the enhanced kinetics, validating this molecular design approach as a new avenue for developing highly stable and efficient HT-PEMFCs.

D-leucine-modified Zr-V coating suppresses localized corrosion of ADC12. • D-leucine seals defects and limits H 2 O/Cl – transport in the coating. • SECM reveals reduced oxygen-consuming local corrosion reactions. • DFT confirmed strong D-leucine adsorption and Zr–O interfacial anchoring on ZrO 2 . ADC12 aluminum (Al) alloy is prone to localized corrosion because its heterogeneous surface microstructure and unstable native oxide film induce spatially non-uniform electrochemical reactions at the alloy/electrolyte interface. Herein, a green D-leucine-assisted zirconium-vanadium conversion coating was fabricated on ADC12 Al alloy via a simple chemical immersion process to regulate coating formation and interfacial electrochemical corrosion behavior. D-leucine acted as a bio-derived interfacial modifier to regulate the deposition, defect evolution and interfacial bonding of Zr-containing oxide/hydroxide species. Surface analyses confirmed the incorporation of D-leucine into the conversion layer and its chemical interaction with Zr-containing species mainly through carboxyl groups, thereby promoting organic-inorganic coupling, defect sealing and coating compactification. The optimized ZRCC+0.5D-AA coating exhibited a low corrosion current density of 4.71×10 −8 A·cm −2 and a corrosion rate of 5.17×10 −4 mm·y −1 , approximately 195 times lower than those of the untreated ADC12 substrate. Scanning electrochemical microscopy further confirmed that D-leucine modification effectively suppressed localized oxygen-consuming corrosion reactions and reduced electrochemical heterogeneity on the coated surface. No visible corrosion was observed after 96 h neutral salt spray exposure. DFT calculations revealed strong dissociative adsorption of D-leucine on monoclinic ZrO 2 (−111), with the vertical bidentate configuration showing a dissociative adsorption reaction energy of −9.88 eV and pronounced interfacial charge redistribution. These results demonstrate that D-leucine-assisted interfacial modification simultaneously regulates coating defects, interfacial anchoring, and local electrochemical activity, providing an effective chromium-free surface finishing and protection strategy for Al alloys.

D-leucine coordinates with Zr-containing species to form a compact organic–inorganic hybrid interface, sealing defect-assisted pathways and reducing H 2 O/Cl⁻ ingress. This limits mass transfer, charge-transfer reactions, cathodic oxygen reduction, and anodic Al dissolution at the coating/substrate interface. DFT and SECM results reveal strong interfacial anchoring and reduced oxygen-consuming local corrosion activity, leading to optimal long-term protection for the coating containing 0.5 g/L D-leucine.

Fast ITAP enables nanofiber sponge crosslinking with low GelMA content. • ITAP reduces crosslinking time by ∼10-fold versus GA-mediated methods. • ITAP preserves the ECM-mimicking porous fibrous architecture. • The nanofiber sponge shows high wettability, water uptake, and wet stability. • The nanofiber sponge exhibits low cytotoxicity and promotes wound healing. Nanofiber sponges have emerged as promising materials for regenerative wound healing, yet their fabrication remains constrained by the use of conventional chemical crosslinkers. Herein, we report a fast ice-template-assisted photocrosslinking (ITAP) strategy for constructing methacryloylated gelatin (GelMA)-based nanofiber sponges. By coupling ice templating with photocrosslinking, this strategy drives the preferential enrichment and in situ fixation of a small amount of GelMA around nanofiber junctions, thereby enabling effective bonding between fibers while preserving the highly porous fibrous architecture resembling the native extracellular matrix. As a result, the crosslinking process is completed within only 3 min, representing an approximately 10-fold reduction in crosslinking time compared with conventional methods mediated by glutaraldehyde. The resulting GelMA-based nanofiber sponge exhibits high porosity (98.2%), superhydrophilicity, high water uptake (∼4500%), compliant mechanical properties, and excellent structural stability under hydrated conditions. Moreover, it shows low cytotoxicity (95% cell viability) and promotes wound repair in a full-thickness skin defect model, including attenuated early inflammatory response, enhanced early CD31-positive response associated with angiogenesis, and organized collagen remodeling with a reduced collagen I/III ratio, ultimately leading to accelerated wound closure (91.47% by day 13) and improved skin repair. In addition, preliminary extension experiments using methacryloylated alginate (AlgMA) and methacryloylated chitosan (ChiMA) suggest the potential applicability of the ITAP strategy to other methacrylated biopolymers. This work establishes an efficient strategy for constructing biocompatible GelMA-based nanofiber sponges and highlights their potential for regenerative wound healing.

Caffeoylquinic acids are natural polyphenolic compounds with notable antioxidant and anti-inflammatory activities. This study developed and validated a sensitive high-performance liquid chromatography-tandem mass spectrometry method for the simultaneous quantification of isochlorogenic acid A (ICQA) and 22 metabolites in serum. The method exhibited excellent sensitivity with limits of quantification of 0.625–1.25 µg/L (signal-to-noise ratio = 10), inter/intra-day precision below 15%, and comprehensive coverage of phase I/II and microbial metabolites. Application of the method in rats and laying hens demonstrated its robustness for pharmacokinetic profiling and cross-species validation, revealing a triphasic metabolic pattern of ICQA, the consistent metabolic endpoints of the accumulation of microbial metabolites, and a critical role of gut microbiota in ICQA metabolism. The developed platform provides a reliable analytical tool for comprehensive metabolism studies of phenolic compounds, with high throughput and reproducibility.

Ferroptosis is triggered by iron-dependent lipid peroxidation, which shows great potential in tumor therapy. However, its biomedical applications are constrained by suboptimal therapeutic efficacy, leakage of metal ions from inducing agents, and the absence of noninvasive evaluation methods. In this study, we aimed to develop a self-reducing nano-theranostic agent (Fe@AP-SAS/RGD, FASR) for tumor-targeted ferroptosis therapy and conducted real-time magnetic resonance imaging(MRI) to monitor ferroptosis by encapsulating iron oxide particles in natural apple pectin (AP). In a weakly acidic tumor microenvironment, the strong reducing ability of AP accelerated the transformation of Fe 3+ within FASR into highly active Fe 2+ . Subsequently, the concentration of Fe 2+ increased and boosted the antitumor effect of ferroptosis. Notably, MRI of prostate cancer mouse models after intravenous injection of FASR NPs at varying doses revealed that the T 2 value decreased at the tumor sites and exhibited a linear correlation with the changes in ferroptosis hallmark markers, tumor weight, and volume after treatment. These findings demonstrate the capacity of T 2 mapping to quantitatively evaluate ferroptosis efficacy. This study not only introduced a tumor-targeted and self-reducing strategy to amplify ferroptosis but also pioneered a novel pathway for noninvasive imaging and monitoring of ferroptosis treatment processes within live tumors.

Volatile organic compounds (VOCs) are important precursors of ozone and secondary organic particulate matter, with an extensive range of sources and complex composition. Dichloromethane (DCM) and n -hexane, as common and typical VOCs, are extensively applied as solvents, extractants and cleaning agents in the pharmaceutical and chemical industries. The persistence, teratogenicity and carcinogenicity seriously harm the ecological environment and human health. In this study, combining the advantages of microbial electrolytic cell (MEC), the detoxification mechanism between low concentration n -hexane and DCM was analyzed. The results demonstrated that the n -hexane favored the enrichment of key functional genera, including degrading and electroactive microorganisms, which could be attributed to the mild toxicity of n -hexane at low concentrations and sufficient carbon sources. In contrast, DCM significantly inhibited the degradation of n -hexane. Metagenomic annotation results suggested that DCM was converted to formaldehyde via hydrolyzing haloalkane dehalogenase (DhlA) or DCM dehalogenase (DcmA). Formaldehyde was partly oxidized to carbon dioxide (CO 2 ) and partly assimilated into the ribulose monophosphate pathway or the serine pathway. And then converted to acetyl-CoA to enter the TCA cycle, which provided energy and material cycles for microbial metabolism. These results provided a new method for the detoxification of mixed VOCs and offer a new insight into the treatment and disposal of pollutants in practical engineering applications.

Effective detection of foodborne pathogenic bacteria is a crucial demand for global food security, yet conventional approaches for detection are often constrained by their reliance on species-specific targets, limiting their capability for broad-spectrum pathogenic bacteria recognition. This study aimed to introduce a novel electrochemical biosensor designed for conserved virulence factor-based broad-spectrum pathogenic bacteria recognition. We combined a prefabricated ready-to-use NaAlg@paper scaffold with a four-channel electrode device including an integrated culture chamber. This setup allowed for rapid cell immobilization on the electrode surface and supported long-term three-dimensional cultivation. The human NLR family apoptosis inhibitory protein–NLR family CARD domain-containing protein 4 (hNAIP–NLRC4) complex was expressed in HEK293 cells to construct HEK293/hNAIP–NLRC4 bioengineered cells as the sensing element, thereby enabling the specific detection of the type III secretion system (T3SS), which is a highly conserved virulence factor. This design effectively eliminated the interference caused by the complex receptor profiles of native immune cells. Based on this strategy, the sensor exhibited a linear range of 2.8 × 10² to 2.8 × 10⁷ CFU/mL for detecting Salmonella typhimurium with a detection limit of 1.7 × 10² CFU/mL. Moreover, this method successfully distinguished pathogenic from nonpathogenic Escherichia coli and specifically detected a broad spectrum of pathogenic bacteria carrying T3SS. These findings demonstrate the potential of conserved virulence factor-oriented biosensing for broad-spectrum recognition of pathogenic bacteria and offer a reliable technical solution to enhance food safety.

Fe/La@MBC adsorbs PSNPs with a Langmuir capacity of 555 mg/g. • Fe/La@MBC maintains >98% removal in real-water matrices. • Magnetic recovery and pyrolysis regeneration retain 85% removal after 5 cycles. • DFT indicates O-containing groups strengthen Fe/La@MBC–PSNP interfacial binding. • Flow-through columns maintain >70% removal after 5 regeneration cycles. Nanoplastics (NPs) are emerging aquatic contaminants with high mobility, colloidal stability, and potential biological accessibility. However, many existing treatment methods mainly transfer captured NPs into a secondary solid phase, leaving NP-bearing residues that still require further handling. To address this issue, Fe-La-modified magnetic almond-shell biochar was prepared as a regenerable adsorbent that integrates nanoplastics capture, magnetic recovery, and pyrolysis-assisted regeneration. Among the prepared materials, Fe/La@MBC-1:1 exhibited the best overall adsorption performance toward polystyrene nanoplastics (PSNPs), with a Langmuir maximum capacity of 555 mg/g. Stable removal behavior was maintained under varying water chemistry conditions and in real-water matrices. Additional tests further showed effective removal at lower PSNPs concentrations and across different particle sizes, surface functionalities, and selected nanoplastic types. The adsorption behavior was associated with enhanced interfacial interactions between Fe/La@MBC-1:1 and nanoplastics, including electrostatic attraction and van der Waals forces. After five adsorption-pyrolysis regeneration cycles, the removal efficiency remained at 85% in batch adsorption and above 70% after the fifth regeneration cycle in flow-through column operation. These results indicate that Fe/La@MBC-1:1 provides a feasible biochar-based route for integrated nanoplastics capture, magnetic recovery, and pyrolysis-assisted regeneration.

Solar-blind ultraviolet polarization detection is critically hindered by the intrinsic isotropy, complex fabrication, and insufficient polarization sensitivity of conventional ultrawide-bandgap (UWBG) semiconductors such as Ga 2 O 3 and h-BN. Here, we break this deadlock by introducing a rationally designed lead-free perovskite analogue, one-dimensional Rb 2 AgCl 3 single crystals, which were synthesized via a spatially confined cooling method. Its unique chain-like lattice endows an ultrawide bandgap of 4.83 eV, exceptional thermal stability up to 934 K, and pronounced in-plane optical anisotropy. Enabled by these attributes, a Schottky-junction self-powered photodetector achieves unprecedented solar-blind ultraviolet performance: a responsivity of 0.2 A/W, specific detectivity of 3.46 × 10 12 Jones, external quantum efficiency of 96%, ultrafast response of 7.9/17.5 µs, and a record dichroic ratio of 15.8 at 255 nm. These metrics not only surpass all reported perovskite-based devices but also rival, and even outperform, state-of-the-art UWBG semiconductors. Furthermore, the detector enables high-fidelity polarization imaging, convolutional neural network integration with >99% recognition accuracy, and a 6 × 6 array encryption system based on physically unclonable function keys. This work elevates low-dimensional lead-free perovskites from mere substitutes to genuine rivals, establishing a transformative platform for intelligent, self-powered solar-blind optoelectronics.

As a promising cathode material for aqueous zinc-ion batteries (AZIBs), layered manganese oxide features high theoretical capacity and low cost. However, its intrinsic semi-conductivity leads to sluggish charge-transfer kinetics, coupled with structural instability triggered by Jahn-Teller distortion. Herein, Ce-doped MnO 2 anchored on carbon nanotubes (Ce-MnO 2 /CNT) was synthesized via an in-situ growth strategy. Specifically, Ce doping induces numerous oxygen vacancies, enlarges the lattice spacing of MnO 2 , and forms robust interfacial chemical bonds with CNTs, thereby synergistically optimizing the electronic structure and ion transport pathways for accelerated reaction kinetics and stability. The Ce-MnO 2 /CNT cathode exhibits substantially enhanced electrochemical performance relative to the un-doped MnO 2 /CNT and pristine MnO 2 . It delivers a high discharge capacity (459.0 mAh g −1 at 0.1 A g −1 ), enhanced rate capability (88.4 mAh g −1 under 3.0 A g −1 ), and robust cycling durability (retaining 82.8% after 300 cycles at 0.3 A g −1 ). Kinetic analyses confirm that Ce doping accelerates ion diffusion and reduces charge transfer resistance. Meanwhile, ex-situ and in-situ characterizations confirm that H + /Zn 2+ dual-ion storage mechanism dominated by H + intercalation/deintercalation. This work proposes a feasible strategy for modulating the electronic structure and interfacial properties of MnO 2 cathodes, offering valuable insights for the pursuit of high-performance AZIBs.
