A facile strategy has been developed for preparing B, N, P co-doped hollow carbon spheres (BNP-HCSs) with adjustable shell thicknesses through a straightforward pyrolysis process of poly (styrene-co-(2-(dimethylamino)ethyl methacrylate))@boronate polymers. The shell thickness of the BNP-HCSs can be relatively controlled by manipulating the monomer concentration. The BNP-HCSs with a moderate shell thickness of 24 nm (BNP-HCS 24 ) exhibits a high capacitance of 357.4 F/g in a 1 M H 2 SO 4 electrolyte at 0.2 A/g. Furthermore, by analyzing the slopes of the discharge curves, we investigate the contributions of faradaic capacitance and electric double-layer capacitance (EDLC) to the total specific capacitance. The results indicate that faradaic capacitance is primarily linked to the effective utilization of heteroatoms, whereas EDLC capacitance correlates with the effective utilization of the BET surface area. The symmetrical two-electrode supercapacitor based on BNP-HCS 24 electrodes delivers an energy density of 8.16 Wh/kg at a power density of 125 W/kg. This study presents a valuable approach for fabricating heteroatom co-doped hollow carbon spheres with tunable shell thicknesses, offering a potential pathway to enhance supercapacitance performance through tailored carbon shell thicknesses. Moreover, the insight into the contributions of EDLC and faradaic capacitance is pivotal for the future development of heteroatom-doped carbon materials for supercapacitors.

Polyvinylidene fluoride (PVDF) and its copolymer-based piezoelectric composites are widely used in piezoelectric sensors to facilitate efficient energy conversion due to their flexibility and high electromechanical coupling properties. In this study, we introduce a piezoelectric nanogenerator (PENG) that utilizes BaTiO 3 –Nb 2 O 5 @PDA@MWCNTs/P(VDF-TrFE) composite films (BNP-MCP) for detecting environmental mechanical stimuli and enabling wireless monitoring. Notably, adding 5 wt% BaTiO 3 –Nb 2 O 5 @PDA@MWCNTs increases the dielectric constant (εᵣ)of BNP-MCP to 21.8 from the 14.8 of pristine P(VDF-TrFE) at 100 Hz, thereby enhancing the PENG's output performance by improving the charge density. By optimizing the BaTiO 3 –Nb 2 O 5 @PDA content in the P(VDF-TrFE) matrix, the fabricated PENG is characterized by an output voltage of 7.5 V and a maximum power density of 4.52 μW cm −2 . This optimized PENG maintains stable performance after 4500 bending-releasing cycles and exhibits high sensitivity in detecting diverse mechanical stimuli, spanning from subtle perturbations (e.g., leaf fall and insect crawling) to intense impacts (e.g., water flow and human jumping). Additionally, an autonomous all-weather rainfall monitoring system leverages wirelessly received piezoelectric signals to trigger real-time precipitation alerts with three-tier warning thresholds: light rain, moderate rain, and heavy rain. This study establishes a sustainable monitoring framework for agricultural and environmental applications, advancing next-generation self-powered sensing technologies.

Revealing the multiple interactions in heterogeneous catalysts and the potential structural evolution under the reaction conditions is crucial for the rational design of catalysts. Herein, we elucidate the complex interactions within P-doped Rh catalysts supported on rutile TiO2 (r-TiO2) and anatase TiO2 (a-TiO2) as well as their structural evolution behavior during CO2 hydrogenation. Before P-doping, Rh/r-TiO2 with Rh ensemble sites primarily catalyzes CO2 methanation, while Rh/a-TiO2 with TiOx-encapsulated Rh sites originating from strong metal–support interaction (SMSI) shows high CO selectivity. P-doping into Rh/r-TiO2 transforms Rh ensemble sites into separated Rh sites, switching the catalytic selectivity from CH4 to CO at low reaction temperatures. Interestingly, the selectivity reverses from 100% CO to 95% CH4 with increasing temperature, demonstrating a dynamic structural evolution. The metastable P-doped Rh species is reconstructed into Rh ensemble and phosphate species due to electronic metal–support interaction and O* intermediate oxidation in a weakly oxidative reaction atmosphere, while it can be regenerated in a H2 atmosphere. For the a-TiO2-supported P-doped Rh catalyst, moderate TiOx encapsulation originating from SMSI contributes to stabilizing the P-doped Rh species during CO2 hydrogenation. Our study reveals that regulating metal–support interaction within TiO2-supported P-doped Rh catalysts can modulate their structural evolution behavior during the reaction, guiding the rational design of P-doped metal catalysts on reducible supports.

Matrix materials with high desorption and ionization efficiency are crucial for the sensitive and accurate metabolite profiling in matrix‐assisted laser desorption ionization mass spectrometry (MALDI‐MS). Herein, we develop an efficient detection platform based on Au nanoparticles decorated mesoporous Cr 2 O 3 (Au@mCr 2 O 3 ) particles with a single primitive continuous structure (i.e., Schwarz P surface) as the matrix. Owing to the low‐tortuosity mesoporous pathways and customized chemical composition, the Au@mCr 2 O 3 exhibits high‐efficiency light absorption and electron transfer, showing great potential for sensitive, reproducible, and selective metabolite detection. Therefore, it is considered as a high‐performance and reliable matrix material for metabolic biomarkers screening. As a proof of concept, the Au@mCr 2 O 3 ‐based detection platform decodes the saliva metabolic fingerprints. With the assistance of machine learning, the platform achieves high diagnostic performance for periodontitis, with the areas under the curve of 0.875–0.934. Furthermore, a simplified biomarker panel is established, which provides a deeper mechanism understanding of the metabolic alternation of periodontitis and offers new insights into its diagnosis and pathogenesis. A non‐invasive periodontitis diagnosis platform was developed using Au nanoparticles‐decorated mesoporous Cr 2 O 3 (Au@mCr 2 O 3 ) particles with Schwarz P surface as matrix for saliva metabolic fingerprinting (SMFs) analysis via MALDI‐MS. With the assistance of machine learning of SMFs, this platform enables efficient diagnosis and the screening of potential biomarkers, thus establishing a simplified diagnostic model and elucidating the possible mechanism about periodontitis pathogenesis.

Electrolyte additive engineering has been demonstrated as an effective strategy to improve electrochemical performance in lithium-ion batteries. However, some additives may induce battery failure during long-term cycling. We found that methyl 2,2-difluoro-2-(fluorosulfonyl)acetate (MDFSA) as an additive induces side reactions due to the coordination interaction between its ester carbonyl group and Cu current collectors. To address this issue, trimethylsilyl 2-(fluorosulfonyl)difluoroacetate (TMS-MDFSA) is designed by trimethylsilyl functionalization to regulate the molecular electron distribution. The introduction of the trimethylsilyl group weakens the p–π conjugation within the ester moiety, leading to electron redistribution around the carbonyl oxygen and a reduced tendency for coordination with the Cu surface. Moreover, the weakened Si–O bond facilitates the self-decomposition of TMS-MDFSA in the electrolyte, eliminating the Cu coordination pathway and generating active species for SEI formation. Notably, the TMS-MDFSA additive promotes the formation of an inorganic-rich solid electrolyte interphase, reducing interfacial impedance and enhancing Li + transport kinetics at low temperatures. After 220 cycles, the cell achieves a capacity retention of 84.8% at −40 °C and 0.1 C. This work provides new insights into the rational design of multifunctional electrolyte additives and the suppression of battery failure under harsh operating conditions. The coordination between methyl 2,2-difluoro-2-(fluorosulfonyl)acetate and Cu triggers Cu dissolution. Trimethylsilyl functionalization modulates p–π conjugation to facilitate the self-decomposition of trimethylsilyl 2-(fluorosulfonyl)difluoroacetate for SEI formation while suppressing Cu dissolution.

The gut-liver axis is a central conduit through which intestinal immunity and metabolism regulate liver health. Although gut probiotics such as Parabacteroides distasonis ( P. distasonis ) and their postbiotics show promise for treating related disorders, safety and stability concerns and inconsistent efficacy limit their further application. Here, outer membrane vesicles (OMVs) derived from P. distasonis are engineered (termed POTA) for enhanced oral delivery. Specifically, biomineralization with tannic acid and encapsulation within calcium alginate microbeads boost their anti-inflammatory properties and enable targeted intestinal release. In mouse models of inflammatory bowel disease, POTA restores intestinal barrier integrity and suppresses inflammation by driving macrophage polarization from an M1 to M2 phenotype via fine-tuned STING signaling. Furthermore, POTA reprograms intestinal immune homeostasis, particularly by rebalancing regulatory T (Treg) and T helper 17 (Th17) cell populations. These changes are supported by a restored microbiota and elevated levels of immunomodulatory bile acids, including isoallolithocholic acid (isoalloLCA). Notably, this localized gut intervention elicits systemic benefits, alleviating hepatic steatosis, inflammation, and insulin resistance in metabolic liver disease. Collectively, engineered bacterial OMVs represent a safe and effective oral platform for ameliorating gut-liver axis disorders.

Mg-based Zintl-phase thermoelectrics are competitive candidates for commercial applications, but the performance of p-type Mg-based AB2X2 Zintl materials still lags behind that of their n-type counterparts. Here, we demonstrate that Li–IV (IV = Si, Ge, Sn) dual doping in the Mg2ZnSb2 lattice effectively decouples the optimization of the electronic and thermal transport properties. With Mg2.06Zn1–xLixSb2-yGey as an illustration, within a certain total dopant content, the electrical transport properties show little sensitivity to the Li:Ge ratio, while the thermal conductivity can be significantly modulated. Specifically, the samples dual-doped with Li and Ge exhibit carrier concentration behavior and valence band structure similar to those doped with Li alone, whereas their thermal conductivity is dramatically reduced due to Ge introduction. Furthermore, the codoping strategy restrains the bipolar effect in samples doped solely with Ge at intermediate temperatures by increasing the carrier concentration. By combining a relatively low thermal conductivity with a power factor comparable to that of the Li-doped samples, an optimized composition of Mg2.06Zn1.995Li0.005Sb1.975Ge0.025 achieves a peak dimensionless figure of merit (ZT) of 1.14 at 625 K. This work provides an effective approach to selectively reduce thermal conductivity while preserving favorable electrical conductivity and Seebeck coefficient.

Herein, nitrogen, phosphorus, and fluorine codoped MXene (N,P,F-MXene) was synthesized via thermal treatment using 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF6]) as the doping precursor. Comprehensive characterization confirmed the effective incorporation of nitrogen, phosphorus, and fluorine into the MXene lattice. Tribological testing revealed that N,P,F-MXene demonstrated excellent performance as an additive in lubrication, showing significantly reduced friction and wear. Specifically, it achieved an average COF of 0.109 and reduced wear volume by 62.5% versus the base oil. Furthermore, the N,P,F-MXene-based lubricant exhibited good adaptability under extreme operating conditions, sustaining stable tribological behavior over a broad load, frequency, and temperature range. Notably, its load capacity reached 500 N. Mechanistic analysis indicates that its superior performance originates from the synergistic effects of the physical filling and adsorption of N,P,F-MXene, coupled with the formation of a tribo-chemical film with low shear strength enriched with nitrogen/phosphorus/fluorine compounds and metal oxides in the friction process. This study provides an effective strategy for heteroatom doping of MXene and offers a promising pathway toward high-performance oil-based lubricant additives.

The construction of a p–n semiconductor heterostructure has been recognized as an effective strategy to achieve high-performance gas sensing. However, the opposite resistance change (signal transducer function) behaviors of p-type and n-type sensing materials in response to the same target gas significantly limit the overall transducer function within the p–n heterostructure. In this study, we designed p-NiO/n-ZnO Janus hollow nanofibers that feature an ordered built-in electric field, enabling directed charge separation and confinement of the conduction path to the ZnO outer layer. The design of the Janus architecture effectively mitigates the conflicting electrical responses of p-NiO and n-ZnO to acetone gas. Therefore, the sensors exhibit a response that is threefold higher than mixed NiO/ZnO nanofibers and sevenfold higher than pristine ZnO nanofibers, illustrating the pronounced transducer enhancement enabled by the Janus configuration. Furthermore, by precisely controlling the ZnO shell thickness, we demonstrate a Debye-length-regulated gas-sensing amplification mechanism. This work establishes a general strategy for nanoscale heterostructure engineering, paving the way for the development of high-performance MOS gas sensors with superior signal transducer function.

Abstract Hydrodeoxygenation (HDO) of lignin derivatives is a promising strategy for biomass utilization, but its catalytic performance is often unsatisfactory for non-noble metal catalysts. This hinders the industrialization process of biomass utilization. Herein, we obtained a FeNi-Cop catalyst with a tightly coupled interface between FeNi alloy and NiO by a hydrotalcite-derived strategy. The effect of this interface on the p-cresol HDO was studied by XRD, HRTEM, H2-TPR, NH3-TPD, XPS, in situ FTIR, and DFT calculations. FeNi-Cop catalyst facilitates hydrogen activation and can promote the dehydration reaction of methylcyclohexanol, a key intermediate, through the electronic regulation of the interface and acid sites. High space-time yield (STY) of methylcyclohexane was obtained, and good catalytic performance could be maintained after 10 cycles. This tightly coupled alloy/oxide interface provides a feasible approach for the design of non-noble metal catalysts.

Three structurally distinct modifiers serving as pendant chains were incorporated into a DOPO-functionalized carbon dot (P-CDs)-cured epoxy vitrimer system, effectively regulating its network topology, intermolecular interactions, and transesterification behavior. • The BnVIm[Cl] pendant chain introduced synergistic cation-π and π-π intermolecular interactions, which significantly strengthened intermolecular forces and endowed the composite with excellent mechanical performances (tensile strength of 64.3 MPa, elongation at break of 15.6%, and toughness of 6.1 MJ/m 3 ). • The imidazole ring in the modifier promoted the carbonization of the EP/CDs/BnVIm[Cl] composite during combustion. The optimized composite achieved superior flame retardancy with a high LOI of 32.6% and UL-94 V-0 rating, accompanied by reduced pHRR, THR, and TSP values. • The EP/CDs/BnVIm[Cl]/CF carbon fiber composite exhibited efficient matrix degradation and outstanding recyclability of carbon fibers, realizing effective fiber recycling. Dynamic epoxy vitrimers feature outstanding reprocessability, self-healing performance, and recyclability. Nevertheless, the improved chain mobility derived from dynamic networks typically deteriorates their mechanical properties. Moreover, achieving high flame retardancy without compromising mechanical performance remains a formidable challenge. Herein, three structurally different pendant chains, namely BnVIm[Cl], VIm[Cl], and Bn, were incorporated into a DOPO-functionalized carbon dot (P-CDs)-cured epoxy vitrimer system to modulate its network topology, intermolecular interactions, and transesterification behavior. The results demonstrated that the EP/CDs/BnVIm[Cl]-7 composite delivered optimal comprehensive performance, with a tensile strength of 64.3 MPa, an elongation at break of 15.6%, and a toughness of 6.1 MJ/m 3 . Meanwhile, it exhibited superior flame retardancy, achieving a limiting oxygen index (LOI) of 32.6% and a UL-94 V-0 rating. The peak heat release rate (pHRR), total heat release (THR), and total smoke production (TSP) were reduced by 30.1%, 13.9%, and 18.9%, respectively. Furthermore, EP/CDs/BnVIm[Cl]-7 exhibited rapid stress relaxation, a crack-closure efficiency of 95.23%, a reprocessing efficiency of 93.39%, and effective solvent-mediated degradability, which enabled efficient resin removal and carbon fiber recovery. The structure-property relationship analysis indicates that the synergistic cation-π and π-π interactions introduced by BnVIm[Cl] strengthen intermolecular forces and increase the effective crosslinking density. Combined with the dynamic β-hydroxyl ester network, a favorable balance between network stability and chain mobility is realized, thereby simultaneously improving the mechanical properties, flame retardancy, and dynamic adaptability of the epoxy vitrimer.

Acaudiolide ameliorates liver fibrosis in mice • Acaudiolide inhibits TGF-β1/SMAD signaling in HSCs • Acaudiolide inhibits the nuclear translocation of p-SMAD2/3 • Acaudiolide weakens the interaction between SMAD4 and p-SMAD2/3 • SMAD4 is a candidate covalent target of acaudiolide Hepatic stellate cell (HSC) activation is a central driver of fibrosis progression in metabolic dysfunction-associated steatohepatitis (MASH), yet effective antifibrotic pharmacotherapies remain limited. Here, we identify acaudiolide, a sulfur-bridged symmetric dimeric macrodiolide isolated from the fungus Acaulium sp. H-JQSF, as a natural-product lead that suppresses HSC activation and experimental liver fibrosis. In a Western diet (WD)/CCl 4 murine model of MASH, acaudiolide reduced collagen deposition, alpha-smooth muscle actin (α-SMA) expression and fibrogenic gene expression. Transcriptomic profiling of HSCs showed that acaudiolide antagonized transforming growth factor-β1 (TGF-β1)-driven profibrotic programs. Mechanistically, acaudiolide did not measurably alter SMAD2/3 phosphorylation but markedly reduced the nuclear accumulation of phosphorylated SMAD2/3 (p-SMAD2/3). Integration of Connectivity Map (CMap) analysis with isotopic tandem orthogonal proteolysis-activity-based protein profiling (isoTOP-ABPP) chemical proteomics nominated SMAD4 as a candidate covalent target of acaudiolide. Covalent docking suggested Cys363 as a potential engagement site, and co-immunoprecipitation showed that acaudiolide weakened the association of SMAD4 with p-SMAD2/3. These findings support a model in which acaudiolide interferes with SMAD complex assembly, thereby attenuating TGF-β-dependent profibrotic transcription and HSC activation. Collectively, our data nominate acaudiolide as a preclinical antifibrotic lead and SMAD4 as a potentially tractable downstream node for pharmacological modulation of TGF-β signaling in MASH-related fibrosis.
