In this paper, a two-in-one interfacial integrated system is constructed through in situ encapsulation of 3DOM-TiO₂/Cu₂SnS₃ composite within a polyvinylidene fluoride (PVDF) membrane. The integrated system exhibits strong broadband sunlight absorption across the UV–Vis-NIR spectrum, enabled by the narrow band gap of Cu₂SnS₃ and the three-dimensional ordered macroporous (3DOM) structure of TiO₂. This synergy delivers excellent photothermal conversion performance, accelerating interfacial water evaporation to achieve seawater desalination at the liquid-solid interface. Simultaneously, the 3DOM-TiO₂/Cu₂SnS₃ heterostructure facilitates efficient separation of photogenerated charge carriers. The holes oxidize interfacial water vapor to release protons, while the electrons reduce CO₂ with protons to CO, thereby enabling photocatalytic CO₂ reduction at the gas-solid interface. Synergistically, this photochemical-photothermal coupling achieves a CO yield of 6.84 μmol‧g⁻¹‧h⁻¹ from CO₂ reduction and an evaporation rate of 0.93 kg‧m⁻²‧h⁻¹ in seawater desalination. Furthermore, the PVDF-supported system demonstrates long-term stability and recyclability, producing no secondary pollution and reducing the reaction cost. This work offers significant potential for co-producing solar fuels and freshwater.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"83 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145247589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These biomarkers overcome limitations of traditional liquid biopsy, such as low abundance and rapid clearance of endogenous biomarkers, by enabling quantifiable detection of disease-specific targets in body fluids. Herein, we report a spherical peptide nucleic acid (PNA)-based artificial biomarker system (Gold-Peptide-PNA, GPP) for ultrasensitive analysis of tumor-associated Cathepsin B (CB). The GPP system comprises AuNP-loaded tandem peptide-PNA probes, where the peptide serves as a CB-responsive substrate and linker, while the enzymatically stable PNA acts as a shielded reporter. Upon CB-mediated cleavage in tumor tissues, PNA probes are released into circulation, excreted via urine, and detected using an Nb.<em>Bbv</em>CI-assisted DNA walker based electrochemical sensor. The sensor leverages competitive binding between PNA and a locked DNA walker to trigger methylene blue (MB) signal amplification. In vitro and in vivo studies demonstrated that GPP achieves a detection limit of 17.5 pg/ mL for CB, exhibits robust stability under enzymatic and physiological challenges, and enables tumor-specific fluorescence/electrochemical signal readouts within 2–3 h of post-injection. This work pioneers a multi-functional, enzyme-responsive nanoplatform for non-invasive tumor diagnosis, combining the programmability of PNA with the sensitivity of electrochemical sensing.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"9 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145247587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the chiral fluorinated covalent organic frameworks (PETG-COF-(Δ/Λ)) are proposed by precise condensation of (<em>R</em>/<em>S</em>)-1-phenylethylamine and 2,4,6-triformylphloroglucinol. PETG-COF-(Δ) yields a remarkable H₂O₂ production rate of 4967 μmol·g⁻¹·h⁻¹ in seawater under visible light illumination, representing a 2.3-fold enhancement compared to the achiral counterpart. Experimental results and theoretical calculations demonstrate that the Δ-configured chiral framework enhances the performance of the 2e⁻ oxygen reduction reaction (ORR) by optimizing the adsorption configurations of reactants and intermediates, and facilitating rapid charge carrier migration through the inherent asymmetric electric field of the chiral microenvironment. Notably, fluorination not only broadens light absorption but also creates hydrophobic channels and passivation layers that effectively block Cl⁻ corrosion and ensure activity retention over 66 h in a flow reactor. This work paves a new avenue for solar-driven H₂O₂ synthesis by chiral COFs and a theoretical basis for the design of seawater-adapted photocatalytic systems.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"21 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145247599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of amphiphilic antibacterial agents holds immense significance for the inhibition of microbial activity and biofilm formation in oil-water interface in aircraft fuel tanks. In this study, we developed a hydroxypropyl trimethyl ammonium-O-alkyl chitosan (TTAC), an amphiphilic polymer with hydrophilic quaternary ammonium and hydrophobic alkyl chains, as a novel targeted (fuel-water interface-active) antimicrobial agent for aviation fuel system protection. Characterization was done using FT-IR and ¹H NMR spectroscopy. The water contact angle measurement yielded a result of θ = 75.84°. Antimicrobial performance showed potent activity with MICs of 8 mg/L (<em>Acinetobacter lwoffii</em>), 32 mg/L (<em>Pseudomonas aeruginosa</em>, <em>Acinetobacter soli</em>), 128 mg/L (<em>Shewanella algae</em>) and 64 mg/L (<em>Escherichia coli</em>, <em>Staphylococcus aureus</em>); MBCs were 16, 64, 256, and 128 mg/L respectively. Scanning electron microscopy (SEM) analysis of the fuel-water interface showed the densest biofilm at the interface, which was significantly reduced by TTAC treatment. TTAC treatment enhanced engineering stress by 11.9 % (<em>Acinetobacter lwoffii</em>) and 6.4 % (<em>Pseudomonas aeruginosa</em>) compared to untreated samples after microbial exposure. These results position TTAC as a promising multifunctional additive for next-generation fuel system preservation, offering simultaneous microbial control and metallic substrate protection.

This study developed a pH-responsive multifunctional film using an integrated “stable indicator–antibacterial–antioxidant–indication” strategy. First, unstable cyanidin cation (CC) was loaded into zeolitic imidazolate framework-8 (ZIF-8). Then, ZIF-8-loaded CC (ZIF-8@CC) was combined with gallic acid (GA) and incorporated into a polyvinyl alcohol (PVA) and chitosan (CS) matrix via electrospinning. The multifunctional film was characterized for its morphology, pH response, antibacterial and antioxidant properties, and biocompatibility, then applied in beef preservation. The results showed that the incorporation of CS and ZIF-8@CC significantly improved the hydrophobicity and mechanical strength of the film. The film exhibited broad-spectrum pH-responsive behavior, with color gradually changing from pink to brown within the pH range of 1–12, and high sensitivity toward NH₃·H₂O, along with good color stability. Antibacterial tests demonstrated an inhibition rate of over 95% against common foodborne pathogens, and whole-genome transcriptome analysis revealed the synergistic antibacterial mechanism among ZIF-8/Zn²⁺, CS, and GA. Meanwhile, the film also exhibited excellent antioxidant performance, with a free radical scavenging rate exceeding 86%. When applied in beef preservation, the film not only visually indicated the spoilage process through color changes but also extended the shelf life by 3–4 days. Furthermore, by integrating smartphone RGB analysis technology, real-time and quantitative monitoring of beef freshness was achieved. This study provides a new strategy for developing multifunctional films for intelligent packaging, with potential applications in quality monitoring of fresh foods.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"85 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145247670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, present a sustainable strategy to transform vanadium industry waste—neutralization slag (Ns) into calcium-rich hydroxyapatite (Ns-HAP) for ultrahigh-capacity lead sequestration. Leveraging the abundant calcium sulfate matrix in Ns, Ns-HAP was synthesized via phosphate modification and hydrothermal crystallization, achieving a Ca/P ratio of 1.90 to enhance ion-exchange sites and reduce phosphorus consumption. Multi-technique characterization (XRD, SEM-EDS, XPS, Raman) revealed that Pb²⁺ immobilization by Ns-HAP operates via synergistic mechanisms: rapid surface complexation with hydroxyl/phosphate groups, ion exchange (Ca²⁺ and Pb²⁺), and covalent Pb–O–P bonding via lattice substitution, culminating in the formation of stable hydroxypyromorphite (Pb₁₀(PO₄)₆(OH)₂). The adsorbent exhibited an exceptional maximum Langmuir capacity of 2165.12 mg·g⁻¹, surpassing most reported hydroxyapatite-based materials, while maintaining a relatively high Pb²⁺ selectivity in multi-ion systems (Cd²⁺, Ni²⁺). Thermodynamic analyses confirmed spontaneous (ΔG° = −9.88 kJ·mol⁻¹) and endothermic (ΔH° = 50.92 kJ·mol⁻¹) chemisorption, with kinetics governed by reaction-controlled lattice diffusion. Crucially, Ns-HAP demonstrated robust performance in high-concentration wastewater (6000 mg·L⁻¹ Pb²⁺), achieving &gt;99 % removal efficiency at an optimal dosage of 4 g·L⁻¹.
