Currently, stable thermal management significantly relies on the use of adaptive phase-change materials, while the photothermal regulation caused by surface structures is severely undervalued. As a result, the operating temperature window of self-adaptive material is limited by the phase-change temperature of the material, making it difficult to achieve large-scale applications. Inspired by the structure of butterfly wings, this study designs a silica-based inverse-opal structure to achieve stable thermal management. Results show porous films achieve a max. cooling of 7.3 °C vs. glass, with a 4.3 °C difference between pore sizes. Altering pore size regulates Mie scattering of light, enabling switchable temperature control (51.5–53.5 °C on sample vs. 49∼56.7 °C on glass). This provides a guideline for fabricating self-adaptive surfaces, with significant potential in bionic skin, building energy efficiency, and thermal management of electronics.

Amaranth (AM) is a widely used synthetic azo food colorant that poses severe toxicological risks upon excessive consumption, creating an urgent need for its ultra-sensitive detection. We report a high-performance electrochemical sensor based on the electrostatic co-aggregation of V 2 O 3 @NC and NHCS for the high-fidelity quantification of AM. A unique “capture-and-catalysis” synergistic mechanism governs this composite interface. Specifically, the highly porous NHCS framework provides exceptional capacity to capture and pre-concentrate target molecules while acting as a highly conductive “electronic bridge.” Subsequently, the abundant mixed-valence (V 3+ /V 5+ ) sites of the V 2 O 3 @NC serve as a robust electrocatalytic engine to drive the catalysis, significantly amplifying the AM oxidation signal. Combining electrochemical kinetic analysis with DFT calculations (including HOMO and MEP), we reveal that this electrocatalytic evolution proceeds via a directional 1 H + /2e − transfer mechanism. Under optimal conditions, the V 2 O 3 @NC/NHCS sensor exhibits a broad linear range (0.01–12 µM) and an extremely low LOD of 0.80 nM. Practical analysis of commercial beverages yielded recoveries of 95.0%–104.3%, with results perfectly matching orthogonal UV-Vis cross-validation. This work provides a robust platform for azo dye screening and profound insights into the rational design of “capture-and-catalysis” composite interfaces. Graphical abstract

Black soybean oil (BSO) is a traditional Chinese medicine (TCM) for inflammatory skin disorders, yet its active basis remains unclear. Inspired by BSO preparation's similarity to carbon dot synthesis, we isolated fluorescent carbon-based nanoparticles (BSO-CNPs) from BSO. Analyses confirmed their characteristic nanostructure and fluorescence. Functionally, BSO-CNPs showed potent antioxidant activity, scavenging reactive oxygen species (ROS) and restoring cell viability under in vitro oxidative stress. In murine models of atopic dermatitis, topical BSO-CNPs alleviated clinical symptoms, reduced epidermal hyperplasia, suppressed mast cell infiltration, and downregulated inflammatory cytokines. Mechanistically, BSO-CNPs attenuate the NOD-like receptor family pyrin domain containing 3 (NLRP3)/caspase-1/gasdermin D (GSDMD) pyroptosis pathway by suppressing mitochondrial ROS and stabilizing lysosomal function. Furthermore, BSO-CNPs demonstrated high biosafety in vitro and in vivo . These findings elucidate the material basis of BSO’s therapeutic effects and highlight BSO-CNPs as a novel nanotherapeutic candidate for atopic dermatitis, bridging traditional herbal medicine with modern nanomedicine.

Currently, the repair of bone defects faces multiple challenges, including insufficient angiogenesis and limited osteogenic differentiation capacity, which pose significant obstacles to treatment. In this study, a ternary composite scaffold composed of PCL-nHA-nMgO (PHM) was fabricated using 3D printing technology. After surface modification with a photothermal polydopamine (PDA) coating, a PHM@PDA composite scaffold was obtained. Metformin (Met) and PDA were loaded into GelMA hydrogels to produce GPM hydrogels. The GPM hydrogels were then packed into the PHM@PDA composite scaffolds, resulting in near-infrared region-I (NIR-I)-responsive PHM@PDA/GPM composite scaffolds. The outer GPM layer serves as a three-dimensional in vivo-like microenvironment, providing physical transport channels for cellular nutrient exchange. Upon stimulation by NIR-I, the scaffold enables the dynamic release of Mg 2+ and Met, upregulates the expression of the VEGF and KDR, accelerates vascular network reconstruction, and creates a mild microenvironment conducive to cell proliferation. Furthermore, by activating the PI3K/AKT signaling pathway, it promotes the expression of osteogenesis-related factors (such as transcription factor Sp7, alkaline phosphatase, and osteocalcin), thereby accelerating the osteogenic differentiation process. In vivo animal experiments, micro-CT and tissue staining confirmed that, under near-infrared light (NIR-I) stimulation, this scaffold significantly increased bone mineral density, trabecular bone thickness, and trabecular bone count and demonstrated excellent angiogenic effects. In summary, this NIR-I-responsive composite scaffold can meet the dual requirements of reconstructing the vascular network and promoting osteogenic differentiation, enabling personalized precision therapy and offering a promising new treatment strategy for complex bone defects where vascular regeneration and osteogenic differentiation are challenging.

A novel in situ self-sulfidation approach was devised to fabricate ZnO/ZnS/C ternary nanocomposites as highly stable anodes for alkaline Zn–Ni batteries. Zinc sulfate acted as a dual-purpose precursor, providing both zinc and sulfur, whereas acrylamide served as the carbon source and in situ reductant. In a single-step carbothermal pyrolysis at 800 °C, the carbon matrix converted sulfate ions to sulfide, facilitating the simultaneous generation of electrochemically active ZnO, a protective ZnS layer, and a conductive carbon network during a single thermal treatment. The optimized ZnO/ZnS/C-2 electrode exhibited a discharge capacity of 576.8 mAh g −1 after 600 cycles at 1 C and maintained 513.2 mAh g −1 at 15 C. Under identical conditions at 10C, the ZnO/ZnS/C-2 electrode delivered a capacity of 545.3 mAh g −1 , which is 41.5% higher than that of commercial ZnO (385.4 mAh g −1 ). Upon the current density reverting to 0.2 C, it regained 96.6% of its original capacity, indicating remarkable reversibility. Post-cycling scanning electron microscopy images validated the successful inhibition of zinc dendrite proliferation. The performance improvements arise from the synergistic combination of the protective ZnS layer, the interconnected conductive carbon framework, and the advantageous ZnO/ZnS heterointerface, which collectively boost structural stability and charge transfer kinetics.

Microwave absorption materials play a vital role in electromagnetic compatibility applications, where electromagnetic coupling between dielectric and magnetic components is crucial. However, in most reported systems, the magnetic loss capability is generally weaker than dielectric loss. To address this issue and achieve ultra-high loading of magnetic particles, concave SiC fibers were designed and fabricated via electrospinning, providing abundant active sites and enhanced surface curvature for effective deposition of magnetic components.Fe 3 O 4 nanoparticles were in situ grown on SiC fibers via a hydrothermal method to prepare lightweight Fe 3 O 4 /SiC composite fiber microwave absorbers. Systematic investigations reveal that an appropriate Fe 3 O 4 loading uniformly covers the fiber surface, forming abundant heterointerfaces and enhancing dielectric and magnetic loss.Query A high Fe 3 O 4 loading of up to 90 wt% was successfully achieved in the composite system.The Fe 3 O 4 -1:2 sample achieves a minimum reflection loss (RLmin) of−40.62 dB at 6.95 GHz with a 4.0 mm thickness, effectively absorbing over 99.99% of incident electromagnetic waves and exhibiting a wide absorption bandwidth. These results indicate that the synergistic dielectric–magnetic loss and multi-interface polarization mechanisms significantly improve electromagnetic wave absorption, providing a promising strategy for designing lightweight, high-performance ceramic-based absorbers.

Lithium oxalate (Li 2 C 2 O 4 ) is a promising cathode prelithiation reagent but suffers from a high activation voltage (>4.6 V). Herein, we establish a component–electronic structure–activity correlation by constructing a series of transition metal-loaded N,S co-doped carbon catalysts (M/NSC, M = Fe, Co, Ni, Ru, Rh, Ir). Distinct catalytic behaviors originate from metal-dependent electronic structures and their interactions with N/S co-doped carbon. Interestingly, the Fe-group metals exhibit stronger electronic coupling and higher redox flexibility than 4d/5d noble metals, resulting in more effective activation of Li 2 C 2 O 4 . The Co/NSC achieves the lowest decomposition voltage (4.17 V), attributed to uniform Co dispersion, optimized Co–N/S coordination, and defect-induced charge-transfer enhancement. The Co/NSC–Li 2 C 2 O 4 composite ensures nearly complete decomposition and delivers superior prelithiation performance. When applied to commercial LFP and NCM9055 cathodes, the Gr|| LiFePO 4 system shows a 22% capacity increase, meanwhile the Gr/SiC||NCM9055 cell achieves an initial coulombic efficiency (ICE) enhancement from 77% to 85.6%. This work highlights electronic–structure engineering as an effective strategy for enabling practical lithium compensation in high-energy lithium-ion batteries. Graphical Unlocking the structure–activity relationship of Li 2 C 2 O 4 prelithiation: uniformly dispersed Co nanoparticles on N,S co-doped carbon creates abundant active sites, Co–N/Co–S coordination modulates electronic structure, and defect-rich carbon ensures fast charge transfer. These structural advantages reduce decomposition voltage to 4.17 V and exhibit a capacity enhancement of 22%.

Visible-light-driven photocatalysis offers a sustainable strategy to eliminate indoor volatile organic compounds (VOCs) like acetaldehyde (AA), thereby improving indoor air quality. Although heterojunctions based on MoS 2 quantum dots (MQDs) attract attention for oxidation reactions, MQDs/WO 3 composites for VOC removal remain largely underexplored. In this study, MQDs/WO 3 heterojunctions were constructed by coupling MQDs with monoclinic (m-WO 3 ) and hexagonal (h-WO 3 ) phases to systematically investigate phase-dependent charge transfer, reactive oxygen species (ROS) generation, and AA degradation pathways. Comprehensive characterizations indicated that MQDs incorporation increased oxygen vacancies, promoted ROS generation, and enhanced visible-light absorption. Furthermore, PL and in situ DRIFTS analyses revealed that MQDs/m-WO 3 exhibited superior electron-hole separation and stronger surface reactivity than the h-WO 3 system. DFT calculations confirmed MQDs as the primary adsorption sites for indoor VOCs, with MQDs/m-WO 3 exhibiting stronger AA adsorption. Consequently, the optimized 0.5MQDs/m-WO 3 demonstrated enhanced AA degradation and mineralization under visible light, exhibiting excellent stability under indoor-relevant operating conditions. This work provides profound insights into interface-regulated charge transfer and offers a promising material design strategy for advanced indoor air purification.

The pyrolysis of energetic materials (EMs) directly determines their combustion performance and energy release efficiency. This study designed a potassium-doped maghemite (KF) catalyst with sea urchin-like structure. Traditional lead-based catalyst could cause serious environmental pollution, whereas KF may offer dual advantages of flame suppression and high catalytic activity. Electron paramagnetic resonance (EPR) spectroscopy demonstrate the increased defect concentration compared with commercial γ-Fe 2 O 3 and α-Fe 2 O 3 . The as-prepared KF catalyst provides more surface active sites, significantly enhancing its catalytic performance for the thermal decomposition of hexanitrohexaazaisowurtzitane (CL-20). Graphene oxide (GO) always acts as a stabilizer for EMs due to the excellent mechanical properties. Hence, K-γ-Fe 2 O 3 /reduced graphene oxide (KFG) was prepared via the one-step solvothermal method. Experimental results show that the ternary KFG composite can lower both the initial decomposition temperature and the apparent activation energy of CL-20. KFG accelerates the decomposition process of CL-20 and narrows the distribution of gaseous products. This study reveals the synergistic mechanism among potassium, γ-Fe 2 O 3 , and graphene, providing new design strategy and theoretical foundation for highly efficient combustion catalysts applied in solid propellants.

A novel fluorescent lateral flow assay (FLFA) based on a zirconium-based metal aggregation-induced emission luminogen framework (Zr-MAF) is reported for the highly sensitive detection of zearalenone (ZEN) in cereals. A carambola-like Zr-MAF with a high fluorescence quantum yield of 36.9% was synthesized via a hydrothermal method using Zr 4+ and 1,1,2,2-tetra(4-carboxylphenyl) ethylene (TCPE). The prepared Zr-MAF-labeled monoclonal antibody probe exhibited intense luminescence, robust stability, and high affinity toward ZEN, collectively contributing to a significant enhancement in detection sensitivity. Under optimal conditions, the Zr-MAF-FLFA achieved an ultralow detection limit (IC 10 = 0.014 ng/mL) and a sensitivity (IC 50 ) of 0.046 ng/mL, representing a 2.6-fold improvement over traditional gold nanoparticles-based FLFA. Notably, the assay exhibited significant cross-reactivity only with the ZEN homologues α-ZAL, β-ZAL, and β-ZOL, which shared similar electrostatic potentials and substantial 2D molecular similarities with ZEN. Furthermore, the proposed method was successfully applied to real food matrices, including flour, glutinous rice, sweet corn, and glutinous corn, yielding satisfactory recoveries ranging from 85.37% to 106.42%. With detection limits in these food samples (0.68-0.78 µg/kg) falling well below national regulatory limits, this work provides a robust analytical platform for trace mycotoxin monitoring in food safety.

Antibiotic residues have drawn global attention due to its potential risks of drug resistance, allergic reactions and cancer induction. Developing highly sensitive and efficient adsorbents for the detection and adsorption of antibiotics is significantly important. Hence, a novel quantum carbon dots-doped hydrogel (CQDs-DAH) using methacryloyloxyethyltrimethyl ammonium chloride (DMC), acrylamide (AM) and carbon quantum dots (CQDs) was prepared for simultaneous detection and adsorption of sulfisoxazole (SSX). The morphological structure and chemical composition of CQDs-DAH were thoroughly characterized. Remarkably, the hydrogel exhibited excellent selectivity and sensitivity toward SSX, achieving a low detection limit of 3.5 × 10 −4 mg/L and a linear detection range of 0–0.385 mg/L. Additionally, CQDs-DAH demonstrated exceptional adsorption performance in a solution with an initial SSX concentration of 50 mg/L, with a maximum capacity of 36.46 mg/g within just 20 min, following the Temkin isotherm and pseudo-second-order kinetic model. Thermodynamic analysis further revealed that the adsorption process was endothermic in nature. Furthermore, the mechanism underlying the adsorption and detection of SSX by CQDs-DAH was elucidated. CQDs-DAH offered a combination of rapid kinetics, high sensitivity, and dual functionality. This study provides valuable insights into the production of multifunctional adsorbents for the sensitive detection and efficient adsorption of SSX.

The development of highly sensitive and selective platforms for trace Zn 2+ detection is crucial for environmental monitoring and biomedical diagnostics. Herein, a photoelectrochemical (PEC) sensor was constructed using an L-cysteine (L-Cys)-functionalized BiOBr composite, in which surface-interface engineering was adopted to enrich available recognition sites and modulate the interfacial PEC response. Compared with pristine BiOBr, the incorporation of L-Cys introduces abundant Zn 2+ binding functional groups and modifies the local surface environment of BiOBr, thereby enhancing the photocurrent response and enabling the selective recognition of Zn 2+ . The sensor operates through a signal-off mechanism, in which the coordination of Zn 2+ with surface-bound L-Cys forms an interfacial coordination layer that partially hinders mass transport and interfacial charge transfer, resulting in a decrease in photocurrent. Under optimized conditions, the platform exhibits a wide linear response ranging from 0.5 to 40 nmol/L, with a low detection limit of 2.69 nmol/L ( S / N = 3). Furthermore, the applicability of the sensor is validated in real-world scenarios, demonstrating excellent recoveries in tap water, lake water, and complex biological matrices such as HepG2 cell lysates (recoveries, 96.3–108.5%). This work provides a robust strategy for engineering bio-semiconductor interfaces for the detection of essential metal ions in complicated samples.
