Lithium-ion conductor as Li 5 AlO 4 (LAO) with strongly temperature-dependent ionic transport behavior is selected as the representative to build the new types of high-temperature battery. • A phase-transition-mediated interfacial engineering strategy is proposed to reconstruct rigid solid-solid interfaces into adaptive solid-liquid junctions. • Cell FeS 2 ||LiCl-KCl||LAO||Li-B delivers a high discharge capacity of 648.9 mAh g −1 at 400 °C and 10 mA cm −2 . • This work establishes a general strategy for mitigating interfacial polarization and enabling high-rate operation in high-temperature batteries. High-temperature solid-state batteries are promising power sources for aerospace, defense, and extreme-environment applications because of their intrinsic safety and high-power capability. However, conventional solid electrolytes often remain ionically conductive at room temperature, might resulting in capacity degradation cause by unintended lithium-ion transport prior to battery operation. In this work, Li 5 AlO 4 (LAO) is newly selected as the representative solid electrolytes which exhibit strongly temperature-dependent ionic transport behavior, making them suitable for high-temperature batteries with reduced self-discharge risk under battery storage conditions. In addition, we also propose a phase-transition-mediated interfacial engineering strategy, to overcome the high interfacial polarization resistance under practical high-current operation, mainly originated from the rigid and non-reconfigurable solid-solid interface between the electrode and electrolyte. The result indicates that the originally discrete solid-solid interface can be reconstructed into a dynamically adaptive solid-liquid-solid ion-transport junction by introducing a thermally responsive LiCl-KCl interlayer that remains solid during battery assembly but undergoes in situ liquefaction at the operating temperature. This interface rebuilt approach significantly improves interfacial contact, reduces interfacial resistance, and facilitates more efficient ionic flux transfer across the cathode/electrolyte interface. As a result, the internal resistance is dramatically reduced from 37.26 Ω to 0.81 Ω, while the optimized FeS 2 ||LiCl-KCl||LAO||Li-B cell delivers a high specific capacity of 648.9 mAh g −1 at 400 °C and 10 mA cm −2 . This work demonstrates that phase-transition-mediated interfacial reconstruction provides an effective strategy for regulating interfacial ion transport and mitigating polarization in high-temperature solid-state batteries, offering a promising route toward safe and high-power electrochemical energy systems for extreme environments.

In Fenton-like processes, achieving rapid and efficient redox cycling of metal active centers remains a challenge. This study presents an innovative strategy that harnesses the mechanical energy of water flow to drive the redox cycling of metal active centers. Herein, Fe 3 O 4 /MoS 2 heterojunction with interfacial Mo-S-Fe bridge bonds was constructed via a one-step hydrothermal method. Under the stimulation induced by water-flow mechanical, the piezoelectric effect of MoS 2 generates charge carriers, which are rapidly directed to Fe active sites through the Mo-S-Fe bonds. This process significantly accelerates the Fe(III)/Fe(II) cycle and enhances H 2 O 2 activation, achieving 93.8% removal of sulfamethoxazole (SMX) within 60 min under water flow stimulation. The composite exhibits robust performance across a broad pH range (3.0-10.7) and in the presence of humic acid (HA) and coexisting anions, demonstrating its strong environmental adaptability. Spectroscopic evidence confirmed the formation of Mo-S-Fe bonds at the heterojunction interface. Mechanistic studies further revealed that the structure improves charge separation, promotes rapid electron transfer from MoS 2 to Fe sites, and strengthens H 2 O 2 adsorption, thereby synergistically boosting reactive oxygen species (ROSs) generation and the overall catalytic efficiency. This study proposes an innovative strategy that exploits mechanical forces generated by water flow to drive rapid redox cycling of active metal centers in Fenton-like reactions.

An environmentally stable Vibrio parahaemolyticus phage 475s1 was isolated. • Phage 475s1 was stably immobilized onto biodegradable PCL films. • The films displayed strong antibacterial efficacy in vitro and in salmon. Vibrio parahaemolyticus ( V. parahaemolyticus ) is recognized as a major foodborne pathogen with global prevalence. The overuse of traditional antibiotics has not only induced the emergence of drug-resistant strains, but also posed a potential threat to human health through the food chain. Therefore, the development of green and precisely targeted antibacterial agents is urgent. In this study, a V. parahaemolyticus phage 475s1 was isolated and exhibited remarkable stability over a broad temperature range (0-70 °C), pH range (4–11) and ultraviolet (UV) irradiation durations (0-60 min). It was capable of lysing 12 out of 23 tested V. parahaemolyticus strains, with a burst size of 110 plaque-forming units (PFU) per infected cell. The phage 475s1 was immobilized onto the surface of biodegradable polycaprolactone (PCL) films. The results showed that the binding density of phage on the PCL films reached 0.04 phages/μm 2 , while the host-capturing density was approximately 0.05 cells/μm 2 . After ultrasonic treatment for 20 min, 35% of the phages remained stably adsorbed on the PCL films. The phage-functionalized PCL films were further applied to artificially contaminated salmon samples. At an incubation temperature of 37 °C, the phage-functionalized PCL films exhibited significant antibacterial efficacy. Compared with the control group, the bacterial concentration decreased by 1.72 log CFU/mL at 2 h and 1.60 log CFU/mL at 3 h, respectively. Therefore, these findings indicate that the V. parahaemolyticus phage-functionalized PCL films hold great promise as a novel and effective antibacterial packaging material. This work provides a feasible green antibacterial strategy against seafood-borne V. parahaemolyticus , offering valuable theoretical support for the development of biodegradable active packaging for industrial aquatic preservation.

Eight post-synthesis acid treatments were systematically compared under identical polyol-derived Pt/C preparation conditions. • Citric acid treatment at pH 2 achieved 99% Pt loading efficiency and an ECSA of 106.2 m 2 gPt −1 . • The citric acid-treated catalyst delivered an ORR mass activity of 0.279 A mgPt −1 , exceeding that of commercial Pt/C. • After 30,000 potential cycles, the citric acid-treated catalyst showed a lower ECSA loss than commercial Pt/C (25.3% vs. 42.3%). Proton exchange membrane fuel cells (PEMFCs) are promising electrochemical energy-conversion devices, but their performance is limited by the sluggish kinetics of the oxygen reduction reaction (ORR). In this study, the effects of post-synthesis acid treatment on polyol-derived Pt/C catalysts supported on Vulcan XC-72 were systematically investigated. Eight chemically distinct acids, including citric, sulfuric, phosphoric, tartaric, oxalic, nitric, acetic, and hydrochloric acids, were compared under otherwise identical preparation conditions, followed by a separate citric-acid dosage series corresponding to final pH values of 2–5. The influences of acid chemistry and post-treatment pH on Pt retention, nanoparticle size and dispersion, Pt surface oxidation state, electrochemically active surface area (ECSA), ORR activity, and durability were evaluated. Thermogravimetric analysis showed that the citric-acid-treated catalyst exhibited a residual Pt fraction of 29.68 wt%, corresponding to approximately 99% of the nominal Pt loading. XRD and TEM analyses revealed Pt crystallite and particle sizes in the range of approximately 2.2–3.8 nm, with the citric-acid-treated catalyst showing relatively small and uniformly dispersed Pt nanoparticles. At pH 2, the citric-acid-treated catalyst achieved the highest ECSA of 106.2 m 2 gPt −1 and an ORR mass activity of 0.279 A mgPt −1 at 0.9 V vs. RHE, exceeding the values measured for commercial Johnson Matthey HiSPEC™ 3000 Pt/C (91.1 m 2 gPt −1 and 0.216 A mgPt −1 , respectively). XPS further showed that the citric-acid-treated catalyst retained a relatively high fraction of metallic Pt, consistent with its favorable electrochemical accessibility and surface state. After 30,000 potential cycles, the citric-acid-treated catalyst exhibited a lower ECSA loss than the commercial reference (25.3% vs. 42.3%) and less XRD-detectable crystallite coarsening. Single-cell measurements under matched cathode Pt loading also showed higher cell voltages for the citric-acid-treated catalyst over the investigated current-density range. These results indicate that post-synthesis citric acid treatment can improve Pt retention, nanoparticle dispersion, electrochemical accessibility, ORR activity, and structural durability through acid-dependent surface and Pt–carbon interfacial effects. The present protocol was demonstrated at a laboratory scale, yielding approximately 80 mg of catalyst per batch.

A RE-doped Bi 4 Ti 3 O 12 perovskite-based luminescence material is developed. • Dual NIR-II emissions of Ho 3+ /Er 3+ are achieved under 980 nm excitation. • High performance (Sr=1.3% K-1) phonon-assisted ratiometric thermometer is constructed. High-performance optical thermometers operating in the second near-infrared (NIR-II) window hold great promise for biomedical applications due to their tissue penetration depth and minimal autofluorescence. However, developing reliable NIR-II thermometers with high sensitivity and robust performance across a wide temperature range remains a challenge. Herein, the luminescence properties and NIR-II ratiometric thermometric performance of Er 3+ , Ho 3+ , Yb 3+ co-doped Bi 4 Ti 3 O 12 (BTO) perovskite oxide were investigated. Upon 980 nm excitation, NIR-II emission from Er 3+ at 1560 nm ( 4 I 13/2 → 4 I 15/2 ) and Ho 3+ at 1200 nm ( 5 I 6 → 5 I 8 ) was achieved. A ratiometric thermometer was constructed using the temperature-dependent intensity ratio, I Er /I Ho . Relying on the thermal dependence of this ratio, the BTO system exhibits a relative sensitivity (S r ) of 1.3% at 333 K. Furthermore, the results suggest that phonon characteristics of the BTO host influence energy-transfer processes and NIR-II thermometric performance, highlighting importance of host properties in designing rare-earth-doped NIR-II thermometric materials.

The detection of hazardous contaminants such as heavy metal ions and pesticide residues in water is essential for safeguarding environmental safety and public health. In this study, boron and nitrogen co-doped carbon dots (B,N-CDs) were synthesized via a one-step hydrothermal method using sodium citrate, urea, and boric acid as precursors. The as-prepared B,N-CDs demonstrated good water solubility, uniform dispersion, a maximum fluorescence emission at 445 nm, and reasonable stability. A fluorescence sensing platform based on B,N-CDs was developed for the sequential detection of Fe 3+ and phoxim using an “on-off-on” mode. The fluorescence of B,N-CDs is efficiently quenched by Fe 3+ through a static quenching mechanism (SQE); subsequent addition of phoxim restores the fluorescence due to competitive binding of phoxim with Fe 3+ . The detection limits for Fe 3+ and phoxim are 3.46 μM and 0.5 mg/L, respectively. In spiked environmental water samples, satisfactory recoveries of 82.7%–95.2% for Fe 3+ and 97.5%–112.0% for phoxim were obtained, with relative standard deviations (RSDs) below 15% ( n = 5). This study presents a promising platform for monitoring Fe 3+ and phoxim in aqueous environments.

Reliable dielectric performance and long-term service stability of polymer insulating coatings under humid environments remain significant challenges, as moisture ingress often induces polarization, accelerates property deterioration, and compromises coating reliability. Herein, a dual-templating strategy is developed to fabricate hierarchical porous polyimide (PI) coatings with enhanced moisture resistance and mechanical integrity. By combining breath figure-induced microporous arrays with polyethylene glycol (PEG)-assisted nanoscale templating, a well-defined multiscale porous architecture is constructed, consisting of ordered honeycomb-like micropores and abundant nanopores distributed within the pore walls. The hierarchical porous structure effectively regulates moisture transport and suppresses water uptake, leading to significantly improved environmental stability under humid conditions. The optimized m-PI-15 coating exhibits a low water absorption of 0.905% and maintains excellent stability after moisture exposure, with only minor increases in dielectric constant (Δκ = 0.156) and dielectric loss (Δtanδ = 0.004). Meanwhile, the coating demonstrates enhanced mechanical performance, achieving a tensile strength of 117.42 MPa, an elongation at break of 70.35%, and a tensile modulus of 1.915 GPa. The superior performance is attributed to the synergistic effect of ordered micropores and interconnected nanopores, which increase moisture diffusion tortuosity while promoting efficient stress redistribution. In addition, the porous coating can be reversibly constructed and removed, enabling repeated structural reconfiguration without significant deterioration in moisture resistance or mechanical properties. This work establishes a clear structure–property relationship for hierarchical porous PI coatings and provides a simple, scalable approach for designing moisture-resistant functional coatings for applications in humid and demanding service environments.

Chronic diabetic wounds heal poorly due to a persistently imbalanced microenvironment involving inflammation and bacterial infection. Notably, oxidative stress, driven by mitochondrial damage, perpetuates inflammation and hinders repair. Existing therapeutic materials struggle to simultaneously address infection, inflammation, and oxidative stress through combined drug delivery and targeted activation of mitophagy. To tackle these intertwined challenges, we designed a bee ovum-inspired hydrogel (BOV) that mimics the parasitic wasp egg strategy, firm host adhesion and staged bioactive secretion, to programmatically remodel the wound microenvironment. The BOV consists of a borate-ester-crosslinked hyaluronic acid network providing robust wet adhesion and self-healing properties. It encapsulates gelatin-coated ZIF-8@Myricetin (Myr) nanoparticles and polyhexamethylene biguanide (PHMB), which are released sequentially in response to the wound’s acidic, high-reactive oxygen species (ROS), and high-matrix metalloproteinase-9 (MMP-9) microenvironment: PHMB first exerts antibacterial action to control infection, followed by Myricetin release to scavenge ROS and suppress inflammation. Beyond antioxidant effects, BOV further activates the SIRT1/FOXO3a/BNIP3 pathway to promote mitophagy, clearing damaged mitochondria and thereby mitigating oxidative stress at its source. In vivo , BOV reduced bacterial burden, alleviated inflammatory response, and enhanced collagen deposition, and re-epithelialization. This study translates a natural parasitic strategy into a programmable drug-delivery platform, offering a promising approach for refractory diabetic wound therapy through microenvironment-responsive sequential treatment and upstream mitochondrial homeostasis restoration.

Deep hydrocarbon resources are recognized as a critical replacement domain for global oil and gas reserves. However, wellbore instability during the application of water-based drilling fluids represents a critical risk for cores, which severely constrains drilling efficiency and operational safety. Herein, a double-walled self-healing microparticles (MPSD) encapsulating epoxy monomer of bisphenol A and luteolin diglycidyl ether composite (BL-DGE) for wellbore stabilization was innovatively proposed and developed. MPSD exhibited a regular spherical morphology with a compact, dense surface, coupled with excellent thermal resistance and mechanical performance. After being immersed in an aqueous environment at 160–200 °C for 16 h, the shale slices treated with MPSD exhibit a shear strength of 634–707 kPa. Furthermore, under high-temperature immersion conditions, the shale cuttings are bonded into an integral structure by MPSD. The permeability of the artificial core treated with MPSD was reduced from 0.95 to 0.162 mD, with a plugging rate of 82.95%. The shell of the microparticles fracture under high-temperature conditions, releasing BL-DGE. By plugging the pores of the rock debris, the loose and fragmented rock is bonded into a dense and stable monolithic structure, significantly improving its mechanical properties and stability. This work provides an important theoretical foundation and technical solution for wellbore stabilization using water-based drilling fluids in deep fractured formations.

A CoMn 2 O 4 /MXene hybrid catalyst was rationally constructed to overcome the sluggish redox kinetics and inefficient interfacial electron transfer. • MXene functions not only as a conductive scaffold but also as an interfacial electronic modulator. • MXene-mediated electronic coupling promotes high-valent metal-oxo species as the dominant reactive intermediates. • Toxicity evaluation confirmed substantially reduced ecotoxicity of the treated BPA-containing water. Selective nonradical oxidation via high-valent metal-oxo (HVMO) species represents a promising yet mechanistically underexplored pathway for eliminating emerging contaminants. Here, a CoMn 2 O 4 /MXene (CMM) hybrid catalyst was rationally constructed to overcome the sluggish redox kinetics and inefficient interfacial electron transfer, which constrain HVMO species generation in spinel oxide/peroxymonosulfate (PMS) systems. MXene acts as both a conductive scaffold and interfacial electronic modulator, accelerating CoMn 2 O 4 -PMS charge transfer and steering PMS activation toward selective nonradical oxidation. The optimized CMM catalyst achieves complete bisphenol A removal within 5 min ( k = 0.98 min −1 ), nearly double the rate of pristine CoMn 2 O 4 . In addition, this system exhibited broad pollutant degradation, high PMS utilization efficiency, wide pH adaptability, and robust tolerance to complex water matrices. Combined experimental and theoretical analyses reveal that MXene-mediated electronic coupling promotes HVMO species as the dominant reactive intermediates. Toxicity evaluation using three-dimensional excitation-emission matrix (3D-EEM) fluorescence spectroscopy and mung bean germination assays confirmed substantially reduced ecotoxicity of the treated BPA-containing water. Continuous flow operation further demonstrated near-complete BPA removal over 6 h, underscoring practical scalability. This work highlights interfacial electronic regulation as an effective strategy for engineering HVMO-mediated routes in advanced water purification.

Facile one-step fabrication of a multifunctional coating on Zn implants under mild conditions. • Gradient coating controls Zn 2 ⁺ release and prevents excessive ion cytotoxicity. • Zn/Ca/Sr synergy enhances dual osteogenic and antibacterial activities. Biodegradable zinc (Zn)-based implants are emerging as one of the leading candidate materials for orthopedic applications owing to their favorable degradation behavior and mechanical properties; however, their clinical translation is delayed by insufficient surface bioactivity. In this study, a multifunctional composite coating incorporating strontium (Sr) and calcium (Ca) was fabricated on Zn implants via a redox-assisted co-deposition strategy. This method harnesses the strong oxidizing power of permanganate to controllably dissolve the Zn substrate, facilitating the gradient incorporation of Ca 2 ⁺ and Sr 2 ⁺ through hydroxyl-mediated cross-linking and resulting in a composite structure with a concentration gradient. The process is completed within 30 min under mild temperature and atmospheric pressure without the need for specialized equipment. The coating operates through a dual mechanism: it regulates the degradation behavior of the Zn substrate and modulates Zn 2 ⁺ release kinetics to mitigate cytotoxicity from excessive local ion concentrations, while simultaneously leveraging the synergistic effects of Ca 2 ⁺ and Sr 2 ⁺ to enhance hemocompatibility and long-term cytocompatibility. Moreover, the coating promotes osteogenic activity by activating osteogenesis-related signaling pathways and stimulating cell adhesion, spreading, migration, and differentiation, alongside conferring antibacterial properties, thus achieving a balanced osteogenic–antimicrobial functionality. This surface modification strategy offers a novel and scalable approach for engineering biodegradable Zn-based implants, demonstrating strong potential for clinical translation in orthopedics.

Three-level ET cascade relieves bottleneck. • TMB: 5.8x act., 24.2x eff.. • GSH sensing + redox disruption (depletion/ROS). Nanozyme efficiency is fundamentally constrained by interfacial electron transfer (ET) bottlenecks, yet most strategies overlook the rational design of ET pathways. Herein, a ternary NiMo 6 @MIL-100(Fe)/g-C 3 N 4 nanozyme featuring a hierarchical three-level ET cascade was reported: TMB substrates are preconcentrated onto g-C 3 N 4 via π–π stacking (Level I); electrons transfer from g-C 3 N 4 to Fe 3+ nodes of MIL-100(Fe) through interfacial Fe O C bonds (Level II); and finally cascade into the encapsulated NiMo 6 cluster for H 2 O 2 activation and •OH generation (Level III). This design yields higher activity than binary (1.8-fold) and pristine counterparts (5.8-fold), with a 24.2-fold enhancement in catalytic efficiency for TMB. By leveraging glutathione (GSH) as a specific electron cascade interceptor, a colorimetric assay achieves a detection limit of 0.36 μM with excellent selectivity over structurally similar thiols. Beyond sensing, the same cascade efficiently depletes GSH and induces intracellular ROS bursts in HepG2 cells, disrupting tumor redox homeostasis and highlighting its therapeutic potential and establishing a mechanism-driven paradigm for biosensing and cancer therapy. A hierarchical three-level ET cascade transforms electron bottlenecks into a superhighway for GSH sensing and tumor redox therapy.
