Electrolytic seawater splitting is a crucial technical direction for hydrogen energy development. However, electrode corrosion induced by high-concentration chloride (Cl − ) remains a key bottleneck restricting its large-scale application. Though cobalt‑iron layered double hydroxide (CoFe-LDH) has good intrinsic catalytic activity, it is susceptible to Cl − corrosion, leading to degraded catalytic performance. Herein, this study proposes a research strategy for synthesizing tetraborate ion (B 4 O 7 2− ) intercalation and regulated CoFe-LDH (CoFe-BLDH) via a one-step hydrothermal method. Via DFT calculation, In-situ Raman spectroscopy, and other characterization techniques, it was verified that the intercalation of cyclic B 4 O 7 2− not only endows the catalyst with excellent hydrophilicity, promotes the generation of high-valent active species and regulates electron transfer, but also effectively inhibits the competitive adsorption of Cl − through a unique charge repulsion effect. In an alkaline high-chloride environment (1.0 M KOH + 2.0 M NaCl), this material exhibits remarkable catalytic activity with dual functional properties: oxygen evolution reaction (OER): 284 mV@100 mA cm −2 ; hydrogen evolution reaction (HER): 179 mV@10 mA cm −2 , representing activity improvements of approximately 21.6% and 11.8%. The overall water splitting constructed with CoFe-BLDH delivers a current flux of 100 mA cm −2 at a working voltage of only 1.820 V in a harsh high-chloride system and can exhibit stable performance for more than 100 h. This study provides practical theoretical guidance for improving the performance of layered double hydroxides in high-chloride media.

Quantum-sized SnO2 nanoparticles (NPs) have emerged as a promising electron transport layer (ETL) in solution-processed quantum dot light-emitting diodes (QLEDs) due to their high chemical stability and excellent optical transparency. However, the intrinsically high electron mobility of SnO2 tends to cause excessive electron injection and charge transport imbalance, ultimately compromising the efficiency and operational stability of QLED devices. To address this issue, we propose an n-type fluorine-doping strategy for SnO2 NPs that simultaneously tailors both electron mobility and electrical conductivity. This approach effectively lowers the electron mobility of the SnO2 NPs to better match the hole mobility of the hole transport layer (HTL), while simultaneously enhancing electrical conductivity to promote efficient electron injection. The resulting more balanced charge transport within the QLED leads to significantly improved overall device performance. As a result, the red-emitting inverted QLED device based on 10 at% F-doped SnO2 NPs exhibits outstanding performance, achieving a maximum luminance of 129 117 cd m−2, a peak external quantum efficiency (EQE) of 16.55% and a turn-on voltage (Von) of 2.4 V.

Continuous in vivo monitoring of biomarkers remains challenging due to limited sensitivity, integration, and biocompatibility. Here, we report an integrated microneedle-based electrochemiluminescence device (MN-ECLD) for real-time detection of protein biomarkers in interstitial fluid. Leveraging hydrogen-bonded organic frameworks with ultrabright, biocompatible electrochemiluminescence, the emitters were incorporated into porous gold-coated microneedle arrays and regulated via interface-specific Y-shaped probes, enabling efficient coreactant-free signal generation. The device achieved ultrasensitive protein detection in vitro with a linear range of 100 fg/mL to 10 ng/mL, a detection limit of 21.3 fg/mL, and stability over 12 days, delivering an 87-fold sensitivity enhancement over conventional emitters. In vivo, MN-ECLD enabled real-time monitoring of cardiac biomarkers, achieving early warning of acute myocardial infarction in rats and pigs, with biomarker trends consistent with serum ELISA. This work establishes a versatile platform for continuous in vivo diagnostics of acute cardiovascular and metabolic disorders.

Nanocatalysts based on metal-organic frameworks exhibit limited catalytic activity due to their symmetrical inactive structures, thereby restricting their application in nanozyme-linked immunoassays (NLISA). This work constructed geometrically structure expanded Cu-Co bimetallic metal-organic frameworks (GS-CCBM) nanozymes through a two-step hydrothermal and alkali treatment, enabling a specific nanozyme-based immunoassay for the target alpha-fetoprotein (AFP). The constructed GS-CCBM nanozyme demonstrated excellent substrate affinity (Km = 1.79 mM) and H2O2 reaction rate (Vm = 8.569 μmol min-1). Based on this, a signal probe was constructed that enables changes in the absorbance and color of the catalytic system in the presence of the target AFP. Semi-quantitative and quantitative analyses were performed using a self-developed color value extraction system. Under optimized conditions, the constructed NLISA method demonstrated an acceptable working range (0.01–50 ng mL⁻¹) and a sensitive detection limit (LOD = 4.7 pg mL⁻¹) for AFP. This approach innovatively proposes a novel strategy for constructing highly efficient MOF-based nanozymes with catalytic activity, offering a new method for developing novel clinical detection techniques.

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.
