Prussian blue analogues (PBAs) show potential in pollutant degradation, but are often limited by crystal structure regulation and insufficient exposure of active sites. In this study, Bi doping was used to synergistically optimize the crystal structure and electronic environment of CuFe-PBA and construct an efficient CuFe-Bi-3 catalyst for peroxymonosulfate (PMS) activated degradation of tetracycline (TC). The introduction of Bi induces crystal plane reconstruction, enhances the Cu 2+ /Cu + and Fe 3+ /Fe 2+ cycles, and increases the exposure of active sites. The TC degradation rate of CuFe-Bi-3 increased from 72.2 % to 92.1 % within 80 min, and the reaction rate constant increased from 0.01133 to 0.02631 min −1 . Mechanistic studies have shown that Bi regulation promotes the directional generation and utilization of 1 O 2 , constructing a synergistic oxidation pathway dominated by non-free radicals. A comprehensive comparison of EPR signals for various reactive oxygen species showed that the 1 O 2 signal was the strongest, significantly higher than O 2 •- , •OH and SO 4 •- . The system has good stability in various water qualities and a wide pH range, and toxicity assessment also shows that it can effectively reduce the toxicity of degradation products. This study provides theoretical support and application reference for the structure-electronic regulation of PBAs catalysts and Bi doping to construct an environmentally friendly and efficient PMS activation system in a complex water environment.

Glabridin is widely used as a whitening agent in cosmetics, but its cytotoxicity remains a key concern in safety evaluations. In typical cytotoxicity assays, glabridin is dissolved in dimethyl sulfoxide (DMSO) before being added to the cell culture medium because it is insoluble in water. However, our study revealed that when the DMSO solution of glabridin was mixed with cell culture medium, glabridin was rapidly released due to its poor solubility in the DMSO/water mixture. The released glabridin rapidly formed crystals, which failed to enter cells. Consequently, the whitening efficacy of glabridin was reduced. Moreover, the glabridin crystals produced higher cytotoxicity, possibly due to the physical damage caused by their sharp crystalline structures. However, encapsulating glabridin in cyclodextrin (CD) can address these challenges, offering a better approach for glabridin cytotoxicity assays. The CD encapsulation method, compared to the DMSO solution method, not only decreased the cytotoxicity of glabridin but also increased its whitening efficacy. By comparing the efficacy of glabridin dissolved in DMSO and encapsulated in CD, we discovered that the reported cytotoxicity of glabridin may have been overestimated in previous cytotoxicity studies which used DMSO as a solvent, while its whitening efficacy may have been underestimated. These findings not only offer new insights for in vitro studies of glabridin-like reagents, but also facilitate the development of safer and more effective whitening products.

The aviation industry's rapid development highlights aircraft metal corrosion, especially for parts like nacelle lips exposed to varying environments, greatly impacting flight safety. In this paper, we propose a “sandwich” superhydrophobic anticorrosive coating containing ZIF-7, which utilizes nanocontainer technology to achieve rapid environmental response. ZIF-7-encapsulated corrosion inhibitor releases during corrosion, preventing leakage and coating damage. In addition, a superhydrophobic coating has been added on top of the anticorrosive coating, which has been imparted with a surface water contact angle of up to 154 ± 3° and a water sliding angle of about 3°. It also has excellent physical/chemical stability, and it remains superhydrophobic even after repeated mechanical abrasion and acid/alkali immersion. The double-layer structure not only further enhances the ‘labyrinth effect’ and extends the path for corrosive media to reach the metal surface, but also successfully isolates water and oxygen from the surface of the coating, which significantly improves the coating's functionality and anticorrosion performance. The highest impedance modulus of 1.3931 × 10 11 Ω·cm 2 is 10 7 fold higher than that of the bare Al alloy sheet. After 30 days of salt spray experiments to accelerate the corrosion rate, the bare Al alloy sheet corroded significantly smaller on the fifth day, while the ZB/ZnO did not undergo significant changes, and healing occurred at the scratches. Our study introduces ZIF-7 to the field of corrosion protection by superhydrophobic coating, providing insights into practical applications and the field of aircraft lip corrosion protection.

Efficient and clean utilization of coal resources is critical to achieving carbon emission reduction and sustainable energy development. In this study, a series of amphiphilic nitrogen-doped coal-based carbon dots (C 12 ∼ C 18 -NCDs) were synthesized from bituminous coal through a green oxidation-depolymerization process mediated by formic acid and hydrogen peroxide, followed by hydrothermal nitrogen doping, alkylation, and sulfonation. The resulting NCDs exhibited tunable amphiphilicity, as confirmed by comprehensive structural and interfacial characterizations. Increasing the alkyl chain length from C12 to C18 significantly reduced the critical micelle concentration (from 802 to 121 mg/L at 25 °C) and lowered the surface tension at CMC (from 28.13 to 25.31 mN/m). Notably, C 18 -NCDs achieved ultra-low oil-water interfacial tension (0.00119 mN/m) under 10 wt% NaCl and exhibited excellent wettability on hydrophobic paraffin surfaces (contact angle: 44.63°). Furthermore, the amphiphilic NCDs demonstrated outstanding dispersibility for multi-walled carbon nanotubes (MWCNTs), effectively suppressing aggregation due to the synergistic effects of π–π stacking interactions, hydrophobic anchoring from alkyl chains, and electrostatic repulsion induced by sulfonate groups. This work presents a scalable and sustainable approach for converting coal into advanced carbon nanomaterials with multifunctional properties, showing promising potential for applications in petroleum interfacial engineering, fuel emulsification, and nanomaterial dispersion.

Baicalein, which exhibits antioxidant activity and wogonin, with anticancer activity, can be extracted from Scutellaria baicalensis Georgi. Their similar structures pose a challenge to further isolation. Supercritical Fluid-Simulated Moving Bed (SF-SMB) can function as a large-scale green separation process based on the adsorptive difference between them. The adsorption data of baicalein and wogonin on ZorBax SB-CN column in supercritical carbon dioxide/methanol were determined using the Elution by Characteristic Points method and could be well fitted by Langmuir model. At lower temperature or lower density of mobile phase, the adsorption capacity increased, with the maximum being 70.10 kg/m 3 for baicalein and 45.25 kg/m 3 for wogonin. The diffusion coefficients of the baicalein and wogonin were determined by the Taylor-Aris peak broadening method. They decreased with higher pressure, lower temperature, or higher density of the mobile phase. This work offers basic data support for the design of SF-SMB systems and industrial platform technology.

The prevalence of antibiotics in natural aquatic environment has become an emerging class of organic pollutants, impacting both aquatic ecosystems and human health. Herein, spherical mesoporous covalent organic frameworks (SMCOF) was successfully synthesized and employed in the immobilization of OXA-48 β-lactamase through pore adsorption, in which 1,3,5-tris(4-aminophenyl)benzene and 2,5-dimethoxyterephthalaldehyde were utilized as the node and linker, respectively. Structural characterization demonstrated that OXA-48 was successfully adsorbed into the pores of SMCOF, achieving a loading capacity of 546.81 mg/g. Meanwhile, OXA-48@SMCOF maintained the catalytic activity of 62.08 % and 104.98 % after the treatment at 50 °C (pH of 7.4) and 37 °C (pH of 11) for 30 min, respectively. Further, all the catalytic activities of OXA-48@SMCOF remained above 88 % after the incubation in the presence of various organic solvents or proteinase K for 1 h. Moreover, OXA-48@SMCOF retained 53.78 % and 41.18 % of original activity after 15 cycles of reuse and 10 days of storage, respectively, indicating its favorable reusability and storage stability. In the application of degrading antibiotics in lake water samples, OXA-48@SMCOF demonstrated superior degradation performance compared to free OXA-48, attributing to the protective effect of SMCOF. Overall, the present study provides a promising technique to construct high performance immobilized enzymes, which is beneficial for the future application of OXA-48@SMCOF in the degradation of antibiotics during water treatment process.

Solvent extraction is considered as an eco-friendly and efficient technology to extract manganese from an industrial leaching solution based on ores or post-consumer products. However, it is imperative to propose a novel extractant capable of independently and selectively extracting manganese ions from impurities since the separation efficiency of a single extractant is limited. We introduced a novel extractant di-neodecyl ethanedione monoxime (DEM) to extract manganese ions and conducted a comparative extraction analysis with neocapric acid (Versatic 10). The maximum extraction efficiencies of DEM and Versatic 10 separately achieved at 97.34% and 87.62%. And the selectivity tests for the extraction and separation of Mn 2+ and Mg 2+ suggested that DEM exhibited superior selectivity towards manganese ions than Versatic 10. FTIR spectrum analysis, saturation capacity experiments and mass spectrometry suggest that DEM can form a dual-ligand six-membered ring metal complex with manganese or magnesium ions through the formation of coordination bonds of N−O−M and C−O−M (M=Mn 2+ or Mg 2+ ). EDA-NOCV analysis illustrated that the π-backbonding between manganese atoms and extractant ligands contributes to the selectivity separation of manganese and magnesium ions. And the π-backbonding bond between the oxime group (–C=N–OH) and the manganese ion is stronger than that of the carbonyl group (–(C=O)–OH), confirming that DEM demonstrated superior selectivity compared to Versatic 10 in extracting manganese ions from magnesium ions.

Nitro-functionalized NO 2 -MIL-53(Fe) was synthesized by modifying MIL-53(Fe) to enhance persulfate activation for the degradation of tetracycline (TCN). Comparative studies with NH 2 -MIL-53(Fe) and pristine MIL-53(Fe), it was found that NO 2 -MIL-53(Fe) is categorized as an ideal type I isotherm, without observable hysteresis loop. The introduction of nitro-group incorporation significantly increased specific surface area clocking in at 298.3 m 2 /g and an average pore diameter of 3.3 nm, created uniform micropores, and improved adsorption capacity. Structural characterization confirmed Fe(II) generation and electron transfer in NO 2 -MIL-53(Fe), enabling 82.1% TCN removal within 30 min. Radical (SO 4 ·− , ·OH, O 2 ·⁻ ) and non-radical ( 1 O 2 , charge transfer) pathways synergistically drove degradation, as evidenced by quenching experiments and EPR analysis. ESI-Q-TOF MS identified key intermediates, proposing plausible TCN degradation pathways. This study highlights the potential of nitro-functionalized metal-organic frameworks (MOFs) in advanced oxidation processes, emphasizing their enhanced catalytic activity and performance mechanisms, and provides new ideas for the remediation of pollutants in water bodies.

The synergistic integration of redox reactions in the photocatalyst poses a significant challenge for CO 2 photoreduction. Addressing this issue requires the design of spatially proximate redox sites while effectively suppressing charge recombination at these sites. This work offers a pioneering tactic that exploits synergistic redox reactions in close atomic proximity. The deliberate incorporation of palladium and indium into TiO 2 , where the Pd site assists in hole accumulation, accelerates water dissociation, and generates highly active H* species. Meanwhile, adjacent In sites capture photogenerated electrons from TiO 2 , producing reactive intermediates by activating CO 2 . The synergistic incorporation of Pd and In accelerates redox functionality, boosts charge carrier separation, and mitigates recombination at closely situated redox sites. Comprehensive characterizations, including in-situ XPS and FTIR, strengthen these innovative outcomes. The optimized Pd 0.5 -In 1 /TiO 2 photocatalyst achieves nearly 100 % selectivity of CH 4 with a production rate of 30.5 µmol g -1 h −1 without the use of any sacrificial reagent, demonstrating a 25-fold improvement compared to pristine TiO 2 . In-situ infrared spectroscopy further validates that the synergistic doping of metal ions promotes the formation of *CH 3 O and *CHO, key intermediates in the production of CH 4 . This investigation provides valuable insight into the intricate design of coupled redox active sites.

The rapid advancement of renewable energy applications has driven a significant increase in the integration of battery energy storage systems within the construction sector. However, the conversion of electrical energy into heat during charging and discharging cycles can adversely affect battery performance. As building-integrated energy storage systems advance, capturing and reusing waste heat are increasingly recognized as valuable strategies for enhancing building energy efficiency. This study developed a novel flexible composite phase change material (ZES@PW) with a high enthalpy of 162.93 J/g. A battery thermal management model was also established to evaluate the potential of waste heat utilization under varying ambient temperatures and assessed the temperature control and waste heat recovery effectiveness. During the heating season, waste heat recovery led to a 19.61 % to 24.88 % reduction in heating water make-up energy consumption. While in the non-heating season, it reduced domestic hot water heating energy consumption by 2.03 % to 2.42 %. The results confirm that the integration of ZES@PW in thermal management systems not only stabilizes battery temperature but also provides significant energy savings for building heating and domestic hot water systems through the efficient reuse of waste heat.

Pitaya ( Hylocereus polyrhizus ) is one of the subtropical and tropical fruits, has gained global cultivation interest due to its nutritional, medicinal, and economic value. To improve the adaptability of pitaya on islands or soil salinization, it is of great significance to explore the salt tolerance mechanisms of pitaya. While oxalate has been conventionally characterized as an antinutrient metabolite, emerging evidence underscores its dual role as a stress signaling molecule through homeostatic regulation. Here, we demonstrate that dynamic control of oxalate catabolism is essential for pitaya's salt adaptation. Transcriptomic profiling revealed coordinated upregulation of the oxalate-degrading gene HuAAE 3 under salt stress, accompanied by enhanced oxalate accumulation. Notably, the transcription factor HubHLH36 emerged as a central regulator responding to both ionic stress and exogenous oxalate. Molecular validation through yeast one-hybrid and dual-luciferase assays unveiled confirmed that HubHLH36 directly activates HuAAE3 transcription by binding to its promoter. Transient overexpression of HuAAE3 or HubHLH36 in pitaya plants significantly reduced oxalate levels, enhanced salt/oxalate tolerance, and alleviated reactive oxygen species (ROS) accumulation. Conversely, virus-induced gene silencing (VIGS) of these genes elevated oxalate content, compromised stress tolerance, and exacerbated ROS production. Heterologous expression in Arabidopsis further validated the conserved function of HubHLH36-HuAAE3 module in conferring salt/oxalate tolerance with ROS mitigation. Our findings establish a novel transcriptional regulatory module where HubHLH36 modulates oxalate homeostasis via HuAAE3 activation, thereby mitigating oxidative stress under salt stress. These mechanistic insights provide genetic targets and theoretical frameworks for developing salt-tolerant pitaya cultivars, offering promising solutions for sustainable agriculture in saline environments.

Malachite green (MG) is a toxic contaminant commonly found in aquaculture, making its effective removal and detection crucially important. In this study, MIL-100(Fe) was synthesized via a microwave-assisted hydrothermal method under optimized conditions (150 °C, 200 W, 30 min; FeCl₃·6H 2 O:H₃BTC = 2:3). The resulting material exhibited excellent structural stability, a high specific surface area (1169.9 m 2 /g), and a remarkable MG adsorption capacity of 714.29 mg/g. To enable practical application and reusability, MIL-100(Fe) was immobilized onto a melamine sponge (MeS) using polyvinylidene fluoride (PVDF) as binding agent, forming a recyclable MeS/PVDF/MOF composite. When applied for solid-phase extraction of MG in conjunction with UV detection, the composite demonstrated high recovery rates (92.1–99.4 %), a low detection limit (2.29 μg/L), and consistent performance with over 80 % recovery after six reuse cycles in both real fish and wastewater samples. This study presents a simple, efficient and sustainable strategy for the adsorption and detection of MG in aquatic food matrices.
