Prussian blue analogues have attracted significant attention as low-cost electrochromic materials with facile synthesis and stable redox behavior. However, their ion transport limitation impact practical application. To overcome the limitation, in this work a hydrothermal ion exchange strategy is proposed, in which carbon dots are employed as ion carriers. During the hydrothermal process, metal ions carried by the carbon dots in situ replace Fe ions in the Prussian blue films, leading to the formation of Prussian blue analogues films. As the hydrothermal reaction proceeds, carbon dots grow on the surface of the Prussian blue analogues films, yielding a new type of carbon dots/ Prussian blue analogues electrochromic hybrid film. This strategy significantly enhances the electrochromic performance of the film, including rapid response and long-term cycle stability. The constructed device exhibits excellent operational stability, maintaining more than 80% of the initial optical modulation amplitude after 3000 switching cycles over 80,000 s. Achieving the multiple colors (red, green, and yellow) through voltage control holds promising potential for application in the field of multi-color electrochromic displays. The hybrid film shows superior multicolor response, ion diffusion capability, and structural stability. The film opens up promising opportunities in information encryption, and advanced optoelectronic integration.

To develop high-performance electrode materials for potassium-ion hybrid supercapacitors (PICs), a bimetallic metalorganic framework (MOF) CuNi-KHP (Potassium Hydrogen Phthalate) was prepared via a solvothermal method. The material features a 3D architecture constructed by stacking 2D nanosheets, with Cu/Ni bimetallic nodes and a multi-layered structure. Potassium ions were pre-inserted into the MOF using potassium hydrogen phthalate as the ligand, which regulates interlayer interactions and creates hierarchical pores for ion transport. Electrochemical characterizations show that CuNi-KHP exhibits a high specific capacitance of 1568.58 F/g at 0.5 A/g, accompanied by an energy density of 50.52 Wh/kg and a power density of 676.12 W/kg. It also maintains 90.1% capacity retention after 10,000 cycles. The assembled CuNi-KHP//AC hybrid PIC delivers an energy density of 76 Wh/kg and a power density of 812 W/kg at 0.5 A/g, with a Coulombic efficiency of 75% after 10,000 cycles at 1 A/g. These results demonstrate that CuNi-KHP is a promising cathode material for high-performance PICs, owing to its synergistic bimetallic effect and K+-regulated porous structure.

The design and preparation of adsorbents are crucial in the field of wastewater treatment. The composite adsorbents with chitosan (CTS) and metal organic framework (MOF) were fabricated to enhance the diffusion degree of MOF and acid stability of CTS by heating reflux method and effect of ratio of CTS, Cu 2+ and 2-aminoterephthalic acid of the composite adsorbents on adsorption was investigated. The diffusion degree of MOF on the composite adsorbent (CTS-MOF) was enhanced on the basis of FESEM images. The acid instability of CTS on the CTS-MOF was improved as CTS can partly dissolve in solution with pH lower than 4.0, while the composite was stable. The composite material was used to remove anionic dye methyl orange (MO) from contaminated aquatic environments. The adsorption kinetics showed that the adsorption capacities of CTS-MOF, CTS and MOF for MO with concentration of 200 mg/L were 135.49, 34.84 and 58.95 mg/g, respectively, and the adsorption capacity of CTS-MOF increased to 3.89 and 2.30 times, accordingly, compared to that of CTS and the MOF, due to synergetic effect of CTS and MOF. The adsorption process of CTS-MOF followed pseudo-second-order kinetic model and Langmuir model. In addition, the adsorption was endothermic. For CTS-MOF, the solution pH exhibited slightly small fluctuation on MO adsorption. The presence of NaCl exhibited positive effect for MO adsorption onto the MOF while negative effect for MO onto CTS-MOF, and the influence on the CTS-MOF was much less than that onto the MOF, indicating the salt tolerance of CTS-MOF was better. Adsorption mechanism was analyzed by the FTIR spectra before and after adsorption and quantum chemical calculation by means of independent gradient model based on Hirshfeld partition (IGMH) analysis. And IGMH analysis showed the relative magnitude of coordination effect, hydrogen bonding and π-π stacking involved in the adsorption process. This study provided a valuable method to design and prepare adsorbents with high adsorption efficiencies for organic dyes from aqueous solution.

Hydrogenated nitrile butadiene rubber (HNBR) is a crucial material for high-performance sealing applications; however, conventional solution hydrogenation is often limited by high noble-metal consumption and the challenges in simultaneously achieving high activity, selectivity and stability. Herein, a synergistic design strategy integrating mass transfer enhancement, bimetallic electronic synergy, and support interface stabilization is proposed for efficient NBR hydrogenation. A Pd-Ni bimetallic-doped TiO 2 -Al 2 O 3 porous composite catalyst was synthesized through a sol–gel method, in which the pore size distribution was tuned to 15–18 nm by using an F127 template to facilitate macromolecular diffusion. Partial substitution of Pd with Ni modulates the electronic structure of Pd sites, promoting H 2 dissociation and selective C=C bond hydrogenation, while the TiO 2 -Al 2 O 3 composite support provides Lewis acid–base sites and oxygen vacancies that enhance metal dispersion and catalyst stability. The optimized Pd–1Ni catalyst achieves a hydrogenation degree of 92% at 120 °C and 4 MPa, and retains over 80% of its activity after five consecutive cycles. This work demonstrates an effective strategy for balancing catalytic activity, noble-metal utilization, and operational stability in heterogeneous NBR hydrogenation systems, providing a practical reference for catalyst design in polymer hydrogenation processes.

Micro quantum-dots light-emitting diodes (Micro-QLEDs) is a pivotal evolution in QLEDs displays. Inheriting the advantages of conventional QLEDs, such as wide color gamut, narrow emission bandwidth, and self-emissive properties while achieving ultra-small size. However, current fabrication methods for Micro-QLEDs are limited by complex processing, efficiency degradation, and high manufacturing costs, which hinder their commercialization. In this study, we employ an all inkjet-printing (AIJP) approach to overcome the compatibility limitations of conventional inkjet processes. In particular, A self-emissive red Micro-QLEDs with the structure ITO/PEDOT:PSS/TFB/QD/ZnO/Ag by stacking 5-soluble layers without intermixing. Its size has been scaled down to 30 μm—the smallest light-emitting area QLEDs for AIJP reported to date. The red Micro-QLEDs achieves the maximum external quantum efficiency (EQE) of 7.35% and a current efficiency of 11.19 Cd/A and the highest brightness of 61,377.41 Cd/m 2 . Accurate printing and uniform film formation were realized through systematic ink formulation optimization. The AIJP process offers significant advantages, including simplified fabrication, high material utilization, and independence from photolithography. This work represents a critical step toward the industrial production of full-color Micro-QLEDs displays and demonstrates strong potential for applications.

SiO 2 -based ceramic aerogels have been extensively employed in thermal protection systems due to their lightweight and excellent thermal stability characteristics. However, their inherent brittleness and relatively high infrared transparency severely restrict their applications under extreme service conditions. In this study, the synergistic integration of anti-infrared property and 3D deformability was first achieved, and an anti-infrared ceramic aerogel composite metastructure (anti-infrared CAM) with an origami structure was designed and fabricated. To address the infrared transparency issue of SiO₂, potassium titanate whiskers (PTW) with high infrared reflective properties were introduced into the SiO₂ aerogel, while a TiO₂ coating was deposited on the fiber surfaces to construct a dual infrared barrier system. The results showed that the prepared anti-infrared CAM exhibited a high uniaxial tensile strain exceeding 80 % and excellent cyclic tensile fatigue resistance. Notably, the introduction of PTW enhanced the anti-infrared capability, making anti-infrared CAM possessed highly efficient high-temperature thermal insulation performance. Although the TiO 2 -coated fibers as the structural framework reduced the tensile strain, they improved the compressive strength. Therefore, the anti-infrared CAM broke through the limitations of brittleness and high infrared transparency in traditional SiO₂-based ceramic aerogels, significantly expanding the application in harsh and complex extreme environments.

Early detection of Bactrocera dorsalis ( B. dorsalis ) infestation in citrus is challenging due to the asymptomatic nature of initial larval stages. Colorimetric sensor arrays (CSAs) are promising for non-destructive detection of B. dorsalis infestations in citrus, yet they still face limitations in reliably identifying the key volatile organic compounds (VOCs) released by infested citrus. In this study, we developed a MOF-enhanced colorimetric sensor array integrating pH-sensitive dyes into ZIF-7 nanoparticles for non-invasive detection. The array detected VOCs associated with early infestation, including D -limonene, decanal, and linalool, identified via GC-MS. The dye/ZIF-7 composite CSA exhibited enhanced sensitivity compared to the pure dye sensor array. Furthermore, across the 4-day test period, infested samples registered a progressive rise in total Euclidean distance (ED) of color change, reaching a 171.7-unit increase over healthy controls on day 4. To enhance the accuracy and efficiency of infestation detection, we implemented a machine-learning pipeline using Dung Beetle Optimizer (DBO) for feature selection and Tree-structured Parzen Estimator (TPE) for hyperparameter tuning. Consequently, the XGBoost classifier achieved a peak test accuracy of 97.15 %, enabling reliable detection during the early stage of infestation. Overall, this study offers a non-destructive and cost-effective approach for batch-mode early detection of B. dorsalis infestation in citrus, advancing the potential for enhanced postharvest monitoring and pest management strategies.

Advanced oxidation process of inorganic peroxide activation is regarded as an effective and reliable method for antibiotics removal. In this paper, we report on the development of Fe-O-coordinated porous honeycomb carbon nanofiber (Fe-O-HCNF) as a high-performance catalyst for rapid degradation of tetracycline (TC) by activation of peroxymonosulfate (PMS). The effects of Fe-O-HCNF dose, PMS concentration, and initial pH were systematically investigated. The results showed that such Fe-O-HCNF achieved a high TC degradation efficiency of 84.7% within 15 minutes. Notably, complete TC degradation (100%) was achieved within 8 minutes at an low catalyst dosage of 0.08 g/L. The Fe-O-HCNF possessing exceptionally high specific surface area of 691.501 m²g-1 provides abundant adsorption and activation sites for the degradation reaction, while the introduction of iron is essential for the continuous activation of PMS. The electron paramagnetic resonance and quenching experiments results indicated that, in addition to sulfate (•SO4−) and hydroxyl (•OH), both singlet oxygen (1O2) and superoxide (•O2−) contribute to the degradation of TC. More interestingly, the Fe-O-HCNF /PMS system showed almost no interference in the real water matrices and various initial pH conditions. Importantly, no metal ion leaching was detected in the treated effluent, indicating minimal secondary environmental contamination risks from heavy metal leaching.

We propose a dual-defect engineering approach for boosting the oxygen evolution reaction (OER) performance of CoOOH, implemented through the simultaneous incorporation of sulfur dopants and cobalt vacancies to tailor its electronic structure. First-principles calculations indicate that this synergistic interaction efficiently refines the binding geometry of key intermediates, leading to a substantial decrease in the energy barrier associated with the rate-determining step. Electrochemical characterization confirms the optimized catalyst's exceptional performance, delivering a low overpotential of 251.4 mV to reach 10 mA cm−2 and a Tafel slope of 51.8 mV dec−1 in 1 M KOH.

Seed-mediated vivianite crystallization offers a sustainable route for recovering phosphorus (P) from wastewater while producing a value-added ferrous-phosphate product. However, fines formation and the absence of mechanism-based design strategies still constrain its application. Herein, a seed-mediated approach was developed to control the crystallization process and simultaneously elucidate the coupled nucleation–growth mechanism. At a supersaturation index (SI) of 10.83 with 0–50 μm seeds at 6 g/L, P recovery efficiency reached 96.32%, and the mean particle size increased 4.6-fold to 65.83 μm. A low-hydration amorphous ferrous phosphate (AM-FP) initially forms on seed surfaces, and then undergoes solid-state transformation into crystalline vivianite driven by hydration. As crystalline facets develop, solution-mediated ion attachment dominates, promoting crystal coarsening while suppressing new nucleation. This multi-stage process explains the marked reduction of fines and the generation of large, well-ordered crystals suitable for efficient P recovery and separation. The estimated reagent cost of $3.41 per cubic meter is considerably lower than that of struvite recovery ($11.14 per cubic meter), underscoring the economic and technical feasibility of seed-mediated vivianite crystallization for scalable circular-P applications.

Chitosan, as one of the most sustainable biomaterials in green and renewable resources, has been widely practised because of its good biocompatibility and biodegradability. However, the challenge of limited solubility of chitosan in neutral or alkaline media (pH ≥ 6.5) has been clearly pinpointed. In this study , a novel water-soluble and fiber-reactive O -[(2‑hydroxy-3-trimethylammonium)propyl] chloride oxidized chitosan ( O HACOC) was prepared with a view to developing the antibacterial finishing agent of textile fibers. The resulted O HACOC contained dicationic groups of quaternary ammonium salt groups at C6 site and amino groups at C2 position in chitosan backbone, which offered good water solubility and antibacterial activity in the wider pH ranges. The water solubility of O HACOC prepared under the optimized process can reach 23.7 g/100 mL, and its minimum inhibitory concentrations were lower than 0.0625 mg/mL against Escherichia coli and 0.125 mg/mL against Staphylococcus aureus , respectively. Meanwhile, O HACOC also showed the high antioxygenic property. This work provides ideas for the design and development of novel functional chitosan derivatives.

β-Glucosidase (BGL) plays a key role in wine aroma enhancement by hydrolyzing glycosidic precursors; however, its application is limited by instability under harsh winemaking conditions. To address this, we developed an integrated biocatalytic system by immobilizing an acid-tolerant BGL onto functionalized magnetic oak chips (NFOak) via oriented Ni 2+ -histidine coordination. Comprehensive characterization confirmed the fabrication of a porous, magnetic cellulose scaffold. The immobilized BGL exhibited significantly enhanced stability against winemaking stresses (low pH, high ethanol) compared to the free enzyme. Furthermore, magnetic actuation of the biocomposite improved its hydrolytic performance, likely attributed to enhanced mass transfer. When applied to Chardonnay and Marselan wines, the magnetically actuated system effectively hydrolyzed glycosidic precursors, markedly increasing the concentrations of key volatile compounds-such as linalool and ethyl benzoate associated with fruity and floral aroma profiles. The treatment also induced subtle modulations in wine color and phenolic composition. Safety assessments confirmed no nickel leaching and oenologically acceptable iron levels. This work provides a sustainable and efficient strategy for controllable aroma modulation, combining the oenological benefits of a natural oak carrier with the operational controllability of magnetic actuation.
