Interfacial engineering in heterostructure photocatalysts is crucial for efficient charge migration, yet achieving rational and controllable interface design remains a major challenge. In this work, SnIn 4 S 8 nanosheets were in situ grown on the octahedral surface of MIL-101(Cr) to leverage the Lewis acid-base properties of Cr and S, thereby enabling the controlled construction of an ion-coordinated interface. The resulting MIL-101(Cr)@SnIn 4 S 8 heterojunction enabled efficient capture and conversion of CO 2 and H 2 O. Furthermore, the Lewis acid-base coordination induces interfacial electron density redistribution, generating a built-in electric field that drives the formation of an S-scheme heterojunction between MIL-101(Cr) and SnIn 4 S 8 , while simultaneously preserving high‑energy photogenerated electron-hole pairs. Consequently, MIL-101(Cr)@SnIn 4 S 8 exhibited superior CO 2 photoreduction performance with H 2 O in the gas-solid phase, delivering a CO evolution rate of 26.9 μmol·g −1 ·h −1 . This work provides a viable strategy for interfacial engineering and demonstrates the application potential of S-scheme heterojunctions in photocatalytic reactions.

The precise detection of microRNAs (miRNAs) in tumor tissue is vital for the early diagnosis of cancer. In this work, we propose an electrochemiluminescence (ECL) aptasensing strategy for the sensitive detection of miRNA-122 in living cancer cells. To tremendously amplify the ECL response, a zinc-porphyrin-organic framework embraced with ZnO nanoparticles (NPs), which was synthesized through solvothermal synthesis using 5,10,15,20-tetra(4-pyridyl)porphyrin (TPyP) as linking ligand and zinc nitrate as precursor (represented by Zn-TPyP@ZnO), simultaneously served as bioplatform and ECL emitter in the presence of the coreactant K 2 S 2 O 8 . The generation of a microinterface between Zn-TPyP and ZnO NPs endowed fast electron transfer, improved catalytic performance, and superior biocompatibility. These advantages of the Zn-TPyP@ZnO heterojunction confers the system with strong reduction capability toward S 2 O 8 2− to generate SO 4 •− and toward O 2 to produce O 2 •− or •OH, as well as excellent anchoring capability for the miRNA-122-targeted aptamer. Therefore, the developed Zn-TPyP@ZnO-based ECL aptasensor demonstrated a wide linear detection range from 10 fM to 10 nM with an ultralow detection limit of 0.77 fM, accompanied with high selectivity, good stability, and excellent reproducibility. The constructed ECL aptasensor also showed promising application for the detection of miRNA-122 in living cancer cells. Thereby, the present work not only provides a new ECL aptasensing strategy for the sensitive detection of miRNA in living cancer cells but also puts forward the advancement of the early diagnosis of tumors.

Metal-organic frameworks (MOFs), such as Cu-MOF, have emerged as highly efficient tumor drug carriers due to their tunable particle size, adequate adsorption property, and good biocompatibility. In this work, Cu-MOFs with different sizes were synthesized by employing a micelle-confined strategy via controlling the concentration of the polyvinylpyrrolidone (PVP) template. At a PVP concentration of 400 mM, the X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS) results jointly confirmed that Cu-MOF nanoparticles (named as Cu-MOF- 400 ) with an average grain size of 167 nm were successfully synthesized. The Cu-MOF -400 exhibited a good crystal structure with the regular octahedral morphology, and possessed a pore diameter of about 1.83 nm with the elements (Cu, C, and O) distributed evenly on the surfaces. In vitro co-culturing experiments revealed that the Cu-MOF -400 exhibited low cytotoxicity to 293T cells, while achieving antibacterial inhibition rates of 58.3% and 69.1% against Gram-negative bacteria ( Escherichia coli ) and Gram-positive bacteria ( Staphylococcus aureus ), respectively. With the aid of the pore structure, Cu-MOF- 400 had a drug loading efficiency (DLE) of 78.3% for doxorubicin (DOX) within 24 h, and the DOX-loaded system (named as Cu-MOF -400 @DOX) demonstrated significant pH-responsive drug release properties in the tumor microenvironment (pH 5.2), with a cumulative release rate of 54.75% over 72 h, which is 6.3 times higher compared to that under the physiological conditions (pH 7.4), fitting well to the Korsmeyer-Peppas model. In addition, Cu-MOF -400 @DOX inhibited the survival of HeLa tumor cells to 42.2% (a killing rate of 57.8%) at a concentration of 9 μg·mL -1 , which might be due to the good cellular-uptake effect of the drug-loaded system; as the Cu-MOF -400 @DOX achieved complete intracellular localization within 6 h, which significantly facilitated the acid-triggered DOX release. With good cytocompatibility and bactericidal effect, and after DOX loading, the nanosystem displays excellent pH-responsive drug release to efficiently suppress tumor-cell growth in vitro, offering a new strategy for the development of new-type drugs in clinic for tumor treatment and bacterial resistance prevention.

Photocatalytic CO 2 reduction into value-added fuels is an appealing route to store solar energy while mitigating carbon emissions, yet achieving efficient and highly selective hydrocarbon formation in pure water remains challenging. Herein, we report a dopant co-engineering strategy by constructing Ni-doped Bi 2 MoO 6 with abundant oxygen vacancies (Ni x BMO-O V ). An ethylene glycol-mediated synthesis enables vacancy-rich Bi O environments and exposes abundant active sites, thereby strengthening CO 2 adsorption and accelerating interfacial charge transfer to facilitate hydrogenation toward CH 4 . Under simulated solar irradiation using pure H 2 O as the sole proton source, the optimized Ni 0.15 BMO delivers a CH 4 evolution rate of 45.0 μmol·g −1 ·h −1 with an exceptional CH 4 selectivity of 99.1%. Ni incorporation and O V modulate the local electronic structure and charge distribution, thereby affecting the adsorption and activation of CO 2 and intermediates toward the target CH 4 product. This work provides an effective synergistic strategy involving Ni incorporation and oxygen vacancies for regulating electronic structure and reaction pathways toward efficient photocatalytic CO 2 reduction.

Glyphosate is a persistent herbicide that contaminates water and poses health risks, yet conventional removal methods remain limited. Photocatalysis offers a promising alternative but is hindered by issues such as charge recombination, poor light utilization, and the formation of phosphate (PO 4 3- ) by-products. In this study, a coupled system is constructed, comprising ZnIn 2 S 4 nanocage (ZIS-HNCs)/BiOCl mesoporous single-crystal nanosheet (BiOCl MSCN) heterojunction–photocatalytic optical and Fe-modified zeolite fibers, to completely remove glyphosate from aqueous environments. Light radiated from the hollow optical fibers excites the ZIS-HNCs/BiOCl MSCN photocatalyst to generate electron–hole pairs. The formation of a heterojunction between ZIS-HNCs and BiOCl MSCN accelerates interfacial charge transfer, increases the production of holes and electrons, and consequently enhances their performance in degrading glyphosate. PO 4 3- produced from photocatalytic degradation is removed in situ by the Fe-modified zeolite fibers through Fe–O–P coordination and electrostatic adsorption. This suppresses the quenching of photogenerated electron–hole pairs by PO 4 3- , further enhancing the efficiency of glyphosate degradation and inhibiting the formation of phosphate by-products. The photocatalysis–ion adsorption coupling strategy provides a novel and effective approach for the simultaneous removal of pesticide residues from aquatic environments.

Precise atomic-scale interface engineering across the entire pH range remains a formidable challenge for photocatalytic H 2 evolution. Herein, hexamethylenetetramine (HMT) is introduced as a bifunctional surface modifier that spontaneously constructs Pd-N coordination bridges on g-C 3 N 4 . The interfacial Pd-N bonds collectively down-shift the N-p-band center away from the Fermi level, break intrinsic surface charge symmetry of C/N atoms, and fully expose the originally buried N active sites, thereby steering the hydrogen adsorption free energy (|ΔG H* |) toward thermoneutral. Simultaneously, the Pd-N bond confines Pd cluster growth to ∼5 nm, doubling specific surface area and enriching edge active sites that serve as primary proton reduction centers. Transient photoelectric voltage results reveal that the Pd-N electron transfer channel shortens the carrier transfer path and prolongs photoelectron lifetime, enabling quantitative electron delivery under acidic, neutral, and alkaline environments. As a result, the Pd-CN-HMT sample presents an efficient H 2 evolution rate across the entire pH window. This work advances the field by providing a versatile ligand-based strategy to precisely tailor the interfacial electronic structure via strong chemical bonding, offering a distinct and scalable solution for constructing high-performance pH-universal photocatalysts.

The poor bleachability of eucalyptus chemi-mechanical pulp (CMP) is widely recognized as a major challenge in the industry. In order to overcome these challenges, a novel and eco-friendly Hydro-Brightening Pretreatment (HBP) strategy is proposed, with the objective of enhancing the brightness of eucalyptus through the removal of bioactive lumen extractives (LEs) using hot water. The majority compositions of LEs are characterised as ellagic acid, taxifolin and caffeic acid. The disruption of chromophore formation is evidenced by the removal of these LEs. During the bleaching reaction, ellagic acid is converted into quinonoid rings via elimination reactions, and taxifolin is oxidised to form trihydroxy benzoic acid and dicarboxylic acids, while caffeic acid undergoes esterification. In comparison with the LEs retained strategy, the implementation of HBP resulted in an enhancement of the brightness of 2.53% ISO for Eucalyptus grandis CMP, and reached a brightness of 80.85% ISO for Acacia crassicarpa Benth. CMP. Concurrently, the LEs of Eucalyptus grandis manifest notable antioxidative capacity (IC 50 =36.13 for DPPH radical). Consequently, this work provides a strategy that simultaneously enhances CMP bleachability and explores the possibility of extracting high-value antioxidant products from LEs, offering new insights on improving CMP bleachability and potential added-value co-products.

Vacancy-ordered double perovskites have emerged as promising candidates for single-component white light-emitting diodes (WLEDs) owing to their intrinsic broadband emission, dopant-induced color tunability, and stable optoelectronic properties. However, their practical application is limited by the difficulty of obtaining high-quality crystals, as the typically rapid and poorly controlled crystallization processes tend to induce lattice disorder and defect formation. In this work, we report a 4-mercaptobenzoic acid (4MBA)-assisted coprecipitation strategy to synthesize high-quality 3%Sb 3+ -doped Cs 2 ZrCl 6 (CZC:3%Sb (4MBA)) microcrystals (MCs). Despite its non-coordinating nature with the crystal surface, 4MBA functions as an effective kinetic regulator that retards crystallization and enhances growth control, thereby suppressing lattice disorder and defect formation to improve crystal quality. As a result, the optimized CZC:3%Sb (4MBA) MCs achieve a photoluminescence quantum yield (PLQY) of 88%, twice that of the unmodified MCs, while concurrently ensuring excellent ambient and thermal stability. Fabricated WLEDs based on CZC:3%Sb (4MBA) MCs exhibit warm white emission with a high color rendering index (CRI) of 94 and maintain stable operation over 14 h. This work presents an effective strategy for regulating crystal growth to enhance the optical performance of lead-free vacancy-ordered double perovskites, paving the way for high-performance, single-component WLEDs.

Agarwood is a resinous heartwood valued as both a fragrance and a medicinal resource. Here, agarwood samples from four major producing regions (Hainan, China; Vietnam; Indonesia; and Malaysia) were systematically compared using headspace solid-phase microextraction coupled with comprehensive two-dimensional gas chromatography–time-of-flight mass spectrometry (HS-SPME–GC×GC–TOFMS). Tentative identifications were assigned against NIST 2020 with retention indices (RI) calculated from a C7-C30 n-alkane series. After de-duplication across 12 samples, 1990 non-redundant volatile features were obtained. Hydrocarbons (22.0–36.1%) and alcohols (6.5–15.0%) predominated, followed by aldehydes, ketones and esters. Principal component analysis and OPLS-DA achieved clear origin-based discrimination. Relative odor activity value (ROAV) analysis highlighted vanillin, ( E )-2-nonenal, heptanal, 2-undecanone, 2,3-butanedione and 2-ethylhexanol (ROAV ≥ 1) as key aroma-impact volatiles underpinning sweet, fruity and woody notes. These results establish a volatile–aroma linkage for agarwood and provide a chemical basis for origin authentication, industrial quality grading, and standardization of agarwood-derived ingredients.

Mini/Micro-LED backlight systems require color conversion layers that combine submicron size with high absorption efficiency. However, commercial phosphors are difficult to meet this demand due to their relatively large particle size. The Cs 2 MnF 6 system demonstrates a unique advantage due to its intrinsic high absorption efficiency. In this study, submicron-sized Cs 2 MnF 6 was successfully prepared via anti-solvent synthesis method. Furthermore, a Si 4+ reverse doping strategy was employed (Cs 2 MnF 6 :Si 4+ ) to effectively suppress concentration quenching. At the optimal doping concentration, the emission intensity reaches 3523 times that of the undoped Cs 2 MnF 6 host. Subsequently, surface passivation treatment was applied with a Mn 4+ -free Cs 2 SiF 6 coating. This treatment not only suppressed surface quenching, further increasing the luminescence intensity, but also significantly improved the material's moisture resistance. The finally obtained Cs 2 MnF 6 :Si 4+ @Cs 2 SiF 6 phosphor has an average particle size of approximately 800-900 nm and a high absorption efficiency of 48.4%. Its luminescence intensity is 4.25 times that of the un-passivated sample. And this material retained 75% of its initial luminescence intensity after 240 minutes of immersion in deionized water. In contrast, the untreated sample remained only 16.4%. These advancements highlight the significant potential of this material in mini/micro-LED backlight systems, offering new possibilities for the development of next-generation display technologies.

As a bridge between innate sensing and adaptive immunity, the functional state of dendritic cells (DCs) is a critical determinant of protective immune responses. Inflammasome activation can induce a “hyperactive” state characterized by highly activated DCs with preserved viability, enhanced antigen presentation, migration capacity, and IL-1β secretion, representing an ideal condition for eliciting robust cytotoxic T lymphocyte (CTL) responses. However, attempts to apply this state in cancer vaccines face constraints including safety concerns, formulation complexity, and limited control over stimulation strength. Here, we develop a lipid nanoparticle (LNP) platform that combines plasmid DNA (pDNA) with fatty acids to optimize the inflammasome activity and direct DCs toward hyperactivation. Following the establishment and screening of the fatty acid-incorporated plasmid lipid nanoparticle (FA-pLNP) library, a palmitic acid formulation designated PA15 is identified as the lead candidate to induce DC hyperactivation. Mechanistic studies reveal that pDNA provides nuclear factor kappa B (NF-κB)-mediated priming, while palmitic acid promotes NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome assembly, enabling effective interleukin-1β (IL-1β) release and subsequent immune activation. Therapeutic vaccination with PA15 demonstrated significant antitumor efficacy in mouse tumor models. Collectively, this work provides a practical strategy for inducing hyperactive DCs and establishes a general design principle for next-generation cancer vaccines.
