Silica-based functionalized composite aerogels possess the merits of high porosity and versatile properties, and can be utilized as a matrix for lots of applications including shape-stable phase change materials (SSPCMs). In-situ functionalization of silica-based aerogel, which can avoid challenges related to the dispersion of functional filler, presents a valuable but less-explored strategy. Herein, metallic copper-functionalized silica (Cu–SiO 2 ) aerogels were synthesized by co-condensing tetraethyl orthosilicate (TEOS) and 3-aminopropyltriethoxysilane (APTES) in the presence of copper acetate via an ambient pressure drying procedure followed by thermal reduction. The Cu 2+ was initially coordinated to the amino groups in APTES and in-situ anchored on the aerogel skeleton, which was then thermally reduced to metallic copper to fulfill the in-situ functionalization. Erythritol (ET) was then vacuum impregnated into the Cu–SiO 2 aerogels to obtain SSPCMs. The prepared SSPCMs exhibited a high ET loading of 86.9%, corresponding to a high latent heat of 307.5 J g −1 , and reduced supercooling. When the aerogel framework contained 3.46 wt% copper, the thermal conductivity of the SSPCM increased by 83.03% compared with that of pure ET. The SSPCM also showed a photothermal conversion efficiency of 71.82% due to the local surface plasmon resonance effect of metallic copper and the multidirectional light-scattering paths provided by the aerogel. In addition, the SSPCMs exhibited excellent thermal reliability over 100 melting/solidification cycles. Overall, this work presents a novel strategy for the preparation of functionalized silica-based composite aerogels and obtained a novel SSPCM for latent heat storage and solar thermal applications.

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.

The annotation of dietary biomarkers is crucial for nutritional epidemiology. While untargeted liquid chromatography–high-resolution mass spectrometry (LC-HRMS) is a powerful analytical approach, the annotation of dietary biomarkers is hampered by the low specificity of existing public databases, which limits annotation coverage and accuracy. To address this limitation, we developed a novel database construction strategy and a dual-annotation workflow. We first employed an automated, large language model (LLM)-based text-mining pipeline to parse 7339 scientific articles and supplementary materials, creating the Dietary Metabolite Biomarker Database (DMBDB), which contains 4983 nonredundant biomarkers. The LLMs workflow demonstrated high performance, achieving an F1 score of 0.9269 for biomarker name recognition. Subsequently, two complementary annotation strategies were designed: (i) a specialized LC-MS database derived from DMBDB, incorporating predicted retention times and experimental MS/MS spectra for high-confidence matching, and (ii) a structure-guided molecular networking strategy (SGMNS) that uses DMBDB as background knowledge to annotate dietary biomarkers and their metabolites lacking spectral evidence. The framework was validated using untargeted LC-HRMS analysis of urine samples. LC-MS database directly annotated 566 metabolites, and the integration with SGMNS expanded the total number of annotations to 2078. The LLM-driven database construction combined with the dual-strategy annotation framework provides a powerful paradigm for achieving high-coverage and high-accuracy dietary metabolomics.

Nitrate pollution in water necessitates efficient catalytic solutions for its conversion into harmless or valuable products. In this work, a molybdenum-promoted nickel–aluminum alloy (NAMCat) catalyst via alkaline leaching for the hydrogenation reduction of nitrate to N 2 and NH 3 was developed. The catalyst achieves over 99% nitrate conversion with brilliant product selectivity of N 2 /NH 3 under mild conditions. The characterization results revealed that Mo doping critically induces a sponge-like porous architecture and fosters synergistic Ni–Mo active sites, which collectively enhance mass transport, hydrogen activation and reaction kinetics. The catalyst also demonstrates remarkable stability, recyclability, and tolerance to common interfering ions. A reaction mechanism based on the porous and electronic structure of NAMCat was also proposed. This work provides a cost-effective, non-noble-metal catalyst strategy for simultaneous nitrate remediation and nitrogen resource recovery. A molybdenum-promoted Ni–Al alloy catalyst was developed for highly-efficient nitrate hydrogenation to N 2 /NH 3 . It achieved >99% conversion with remarkable stability, recyclability, and tolerance to common interfering ions.

Hollow carbon spheres (HCSs) have emerged as promising anode materials for lithium-ion batteries (LIBs), yet their practical application is hindered by intrinsic limitations. Excessive internal voids reduce the tapped density and volumetric energy density, while poor interparticle connectivity increases transport resistance and compromises rate capability. Here, we present a series of nitrogen-doped hollow carbon sphere clusters (HCSCs) with varying hollow diameters (20 nm, 100 nm, and 300 nm), achieved via a combined spray-drying and solution-stirring approach. The 20-HCSCs with ultra-small cavities (20 nm) markedly enhances tap density, while cluster-level interconnectivity establishes continuous pathways for efficient Li + and electron transport, thereby enabling rapid charge/discharge kinetics and high volumetric capacity. Consequently, the 20-HCSCs electrodes exhibit an exceptional reversible capacity of 447.3 mAh cm -3 after 90 cycles at 0.2 C, surpassing that of 100-HCSCs, 300-HCSCs electrodes and conventional graphite electrodes (around 372 mAh cm -3 ), and demonstrate remarkable high-rate cyclability, retaining 68.5 mAh cm -3 after 3000 cycles at 50 C. The ultrahigh volumetric capacity mitigates the volumetric penalty typically imposed by hollow structures, offering a viable strategy to reconcile high capacity, fast-charging capability, and competitive volumetric performance in carbonaceous anodes.

Triple-negative breast cancer (TNBC) remains a formidable clinical challenge characterized by its aggressive metastasis and a scarcity of effective treatment strategies. However, photodynamic therapy (PDT) is severely limited by the hypoxic tumor microenvironment, and photothermal therapy (PTT) is restricted by the low photothermal conversion efficiency of the photothermal agents. The photosensitizer IR780 has received widespread attention due to its dual potential in both PDT and PTT, but it suffers from insufficient photostability and is prone to fluorescence quenching. To overcome these challenges, this study constructed a multifunctional self-oxygen-supplying biomimetic nanoparticle platform, named CaO2@PDA-IR780@CM (CPIC). In this system, calcium peroxide (CaO2) decomposes in an acidic tumor microenvironment and releases oxygen in situ, effectively alleviating tumor hypoxia and enhancing the PDT efficacy mediated by IR780. Loading IR780 onto polydopamine significantly improved its stability and photothermal performance, achieving a photothermal conversion efficiency of 54.5%, which represents a significant enhancement compared with free IR780. The nanoparticle surface was coated with homologous tumor cell membranes, endowing it with tumor-specific targeting ability. In an orthotopic 4T1 tumor-bearing mouse model, CPIC showed significantly stronger intratumoral fluorescence signals compared with free IR780 and the control nanoparticles without cell membrane coating, thereby confirming its superior tumor targeting efficiency. Furthermore, the combination of PDT/PTT mediated by CPIC significantly suppressed primary tumor growth and effectively inhibited the formation of pulmonary metastatic nodules, highlighting its remarkable translational potential for TNBC treatment.

Spectral information, reflecting the interaction between light and matter across different wavelengths, is essential for identifying material properties and environmental changes. To meet the demand for compact spectral sensors, we constructed a type-I band-aligned MoTe 2 /Te van der Waals (vdW) heterostructure through precise band structure design, where the drain–source voltage ( V ds ) electrostatically tunes interfacial band alignment to complement gate voltage ( V gs ) modulation. By synergistically tuning the V gs and V ds , we achieved a wavelength-dependent photoresponse and constructed a spectral responsivity matrix. Integrated with an attention-guided multilayer perceptron (MLP) algorithm that incorporates the device's responsivity as prior physical information, the device functions as a miniaturized spectrometer, demonstrating narrowband spectral reconstruction with an optimal resolution of 6 nm across a broadband range from 500 to 780 nm at room temperature. The noncentrosymmetric crystal structure of Te also endows the device with the capability of simultaneous polarization discrimination. This work provides a promising approach toward multifunctional on-chip spectrometers capable of simultaneous spectral and polarization analysis.

PB@MSN-CIN nanoparticles enabled CIN release with NIR-triggered photothermal conversion. • S/P-HK bilayer films combined PB@MSN-CIN-loaded P-HK inner layer with a hydrophobic SHL-QCT outer layer. • Regulating the SHL-QCT layer thickness improved moisture barrier, UV shielding, and photothermal retention of the bilayer films. • Under NIR treatment, the optimized S/P-HK film suppressed microbial growth, browning, and water loss of fresh-cut Benincasa hispida . Fresh-cut vegetables are highly susceptible to microbial growth, enzymatic browning, and moisture loss, creating a need for environmentally sustainable active packaging with effective barrier and antimicrobial functions. In this study, a multifunctional bio-based bilayer film (S/P-HK) was developed using the thickness of the hydrophobic outer layer as a key design variable. The inner active layer (P-HK) comprised a konjac glucomannan/hydroxyethyl cellulose matrix containing cinnamaldehyde (CIN)-loaded mesoporous silica nanoparticles coated with Prussian blue (PB@MSN-CIN), whereas the outer layer was composed of quercetin-containing shellac (SHL-QCT). SEM revealed a compact bilayer structure, while FT-IR, XRD, and TGA indicated intermolecular interactions and good thermal stability. Increasing the thickness of SHL-QCT layer enhanced moisture-barrier performance and heat retention under near-infrared (NIR) irradiation. Among which, the S20/P-HK film exhibited nearly complete UV shielding, strong antioxidant activity (DPPH and ABTS radical scavenging rates >80%), excellent antibacterial activity (antibacterial rates >99.99% against Escherichia coli and Staphylococcus aureus ), and controlled release of CIN. During preservation of fresh-cut Benincasa hispida , the S20/P-HK film with NIR irradiation significantly inhibited microbial growth, suppressed the browning index to 0.90 ΔOD₄₂₀·mL/g, and restricted weight loss to 0.26% over 10 days. These findings demonstrate a promising thickness-regulated bilayer design that integrates moisture-barrier protection, NIR-responsive CIN release, and photothermal antibacterial activity for active packaging. Future studies should validate the applicability of S/P-HK films to other perishable foods and evaluate their antifungal efficacy.

Sacrificial template strategy builds ZnO 2 @Hemin-ZIF-8 core-shell structure. • The seamless ZIF-8 shell prevents premature ZnO 2 leakage at physiological pH. • Hierarchical ZnO 2 @Hemin-ZIF-8@PB (ZHZHP) enables on-demand H 2 O 2 release. • ZHZHP enables dual-nanozyme cascade-based CDT and PTT to eradicate bacteria. • ZHZHP orchestrates anti-inflammation and angiogenesis to accelerate wound healing. Chemodynamic therapy (CDT) has emerged as a promising strategy for combating bacterial infections; however, the scarcity of endogenous H 2 O 2 within infection sites often bottlenecks therapeutic efficacy. Herein, a pH-responsive, H 2 O 2 self-supplying nanoplatform is meticulously engineered for spatiotemporally controlled chemodynamic–photothermal antibacterial therapy. This platform leverages ZnO 2 nanoparticles dual-role cores and sacrificial template to drive the in situ epitaxial growth of dense ZIF-8 shells (optionally encapsulated with Hemin), yielding the core–shell ZnO 2 @ZIF-8 (or ZnO 2 @Hemin-ZIF-8) intermediate. Stepwise surface engineering with hyaluronic acid (HA) and Prussian blue (PB) leads to the formation of a hierarchical core–shell structured ZnO 2 @Hemin-ZIF-8@HA@PB nanoplatform (ZHZHP). Under neutral physiological conditions, ZHZHP exhibits excellent stability as the interracially-bonded ZIF-8 shell effectively shields the ZnO 2 core from premature hydrolysis. Conversely, within the weakly acidic infection microenvironment, ZHZHP undergoes programmed disassembly, triggering the on-demand release of H 2 O 2 . Simultaneously, Hemin and PB act as peroxidase mimics to catalyze the conversion of liberated H 2 O 2 into highly toxic hydroxyl radicals (‧OH) via dual nanozyme cascades, while the PB component provides robust photothermal conversion under 808 nm NIR irradiation. This synergistic CDT/PTT approach achieves complete eradication of S. aureus and E. coli at an extremely low concentration of 50 μg mL −1 and demonstrates remarkable efficacy in disrupting both immature and mature biofilms. In vivo assays further confirm that ZHZHP significantly accelerates infected wound healing through potent antimicrobial and anti-inflammatory activities, alongside the promotion of angiogenesis. With high biocompatibility and negligible toxicity, ZHZHP represents a sophisticated strategy for the clinical management of refractory wound infections.

Surface-enhanced Raman scattering (SERS) is a powerful tool for rapid on-site detection of pesticide residues, but its performance heavily relies on the substrate. Herein, a gelatin‑silver nanocube (Ag NC) composite hydrogel SERS substrate was developed via mild EDC-NHS crosslinking coupled with low-temperature gelation. The three-dimensional porous hydrogel efficiently enriches target molecules, while the sharp edges of Ag NCs generate abundant electromagnetic hotspots. Using rhodamine 6G as a probe, the optimized substrate (20% gelatin, Ag NC/gelatin volume ratio 3:1) exhibited good uniformity, reproducibility, and stability. For thiram detection, a linear response was obtained from 10 −4 to 10 −7 M with a limit of detection (LOD) of 4.45 × 10 −8 M in standard solution. Practical applicability was demonstrated in orange juice, where thiram was detected down to 1.0 × 10 −6 M (LOD = 4.78 × 10 −7 M) with recoveries of 96.9–97.9%. This work provides a gelatin-based, stable and sensitive SERS platform for food safety monitoring.

Integrating pollutant detection and degradation into a single material platform is highly desirable for the efficient treatment of dye-contaminated wastewater. However, simultaneously achieving sensitive detection and efficient photocatalytic activity remains challenging because these functions involve distinct interfacial processes. In this work, an Ag NPs@Cu-V 2 O 5 hybrid was prepared through wet-chemical synthesis and calcination of Cu-V 2 O 5 , followed by ultrasonic coupling with preformed Ag nanoparticles. Cu incorporation modulated the local electronic environment of V 2 O 5 , while the supported Ag nanoparticles provided plasmonic SERS-active sites. XPS binding-energy shifts were consistent with interfacial electronic redistribution, FDTD simulations revealed pronounced local-field amplification around the Ag nanoparticles, and energy-level analysis indicated accessible interfacial charge-transfer pathways under 532 nm excitation. Using colorless, non-resonant 4-MBA as a control probe, the hybrid produced a higher Raman response than the Ag NP reference under equivalent Ag loading, indicating that the enhancement was not solely dependent on the molecular pre-resonance behavior of MB. The hybrid enabled MB detection down to 1 × 10⁻⁹ mol L⁻¹ , with good spatial uniformity and approximately 80% signal retention after 28 days. After correction for dark adsorption, it achieved an MB degradation efficiency of 82.3% after 60 min of visible-light irradiation and exhibited higher photocatalytic activity than pristine V 2 O 5 and Cu-V 2 O 5 . These results demonstrate a plasmonic–semiconductor platform that integrates SERS sensing and photocatalytic remediation through Ag-induced local-field amplification, Cu-related electronic modulation, and Ag/Cu-V 2 O 5 interfacial interactions.

Collagen is an ideal raw material for biological fibers, yet achieving long-range structural order and the resultant high-strength fibers without toxic crosslinkers remains a major challenge. This work integrates ultrasonic fragmentation with dialysis concentration to induce a stable lyotropic liquid crystalline (LC) collagen dope at a concentration as low as 3.3%, which is significantly lower than previously reported. Ultrasonic treatment reduced collagen fragment length to 10–30 nm, lowering steric hindrance and enhancing molecular mobility, thereby promoting nematic LC formation. Rheological analysis revealed that at 3.7%, the spinning dope exhibited a characteristic viscosity plateau in the low shear rate range of 1–5 s −1 , indicating shear-induced alignment of nematic LC domains, which defines the optimal spinning window. Using 4.0% LC dope and an optimized ethanol flow rate of 0.30 mL/min in microfluidic spinning process, the resultant collagen fibers achieved a high tensile strength of 2.21 cN/dtex and a thermal denaturation temperature of 120.8 °C. Increasing the spinning dope concentration progressively reduced lateral molecular packing distance, transformed the fiber surface from grooved to smooth, and enhanced thermal stability. This study establishes a rational, crosslinker-free strategy to fabricate high-performance pure collagen fibers with superior mechanical and thermal properties, providing critical theoretical and technical support for their application in absorbable surgical sutures and regenerative medicine.
