In this study, both nZVI and nZVI/Cu exhibited synergistic effects with anaerobic sludge on the treatment of dying wastewater. The decolorization rates in both systems were 17.04–21.97 % higher than that in the sludge alone system during the semi-continuous treatment process. The microbes could maintain their oxidation/antioxidation balance by increasing the activity of enzymes responsible for ROS elimination when nanomaterials were added. The microbial diversity analysis showed that the structure of the microbial community changed, and the dominant genuera were Ethanoligenens and Caproiciproducens. The addition of nanomaterials could help maintain the gas production efficiency of anaerobic sludge. During the last day of the treatment, 33.00 and 31.50 mL of gas could be collected from nZVI and nZVI/Cu addition system, respectively, while the gas production of “sludge alone” system had dropped to 8 mL/d. A ZVI-A/O MFC system was designed and built after optimization. During the continuous wastewater treatment process, the improved system could maintain the decolorization rate of dyes, the removal rates of COD and NH₄⁺-N above 95 %, 85 % and 86 % respectively, which were all significantly higher than those of in the traditional reactors. Moreover, the electrons generated in the MFC system were mainly used for CH₄ production.

在本研究中，nZVI和nZVI/Cu与厌氧污泥在处理垂死废水中均表现出协同效应。在半连续处理过程中，两种系统的脱色率均比污泥单独系统高17.04 ~ 21.97%。当纳米材料加入时，微生物可以通过增加活性氧消除酶的活性来维持其氧化/抗氧化平衡。微生物多样性分析表明，微生物群落结构发生了变化，优势属为寡乙醇属和产豆属。纳米材料的加入有助于维持厌氧污泥的产气效率。在处理的最后一天，nZVI和nZVI/Cu添加系统的气体收集量分别为33.00和31.50 mL，而“单独污泥”系统的产气量已降至8 mL/d。优化后，设计并搭建了ZVI-A/O MFC系统。在废水连续处理过程中，改进后的系统可保持染料的脱色率，COD和NH4+-N的去除率分别在95%、85%和86%以上，均显著高于传统反应器。MFC系统产生的电子主要用于CH4的生成。

Deep eutectic solvents (DESs) were evaluated for their role in enhancing green tea extract (GTE)-based biosynthesis of silver nanoparticles (Ag NPs). Four types of DESs with varying water contents (10–50 %) and hydrogen bond acceptor (HBA) mole fractions (0.17–0.83) were evaluated. While HBA composition had little effect on catechin and phenolic compound extraction, higher water content usually improved yields by reducing DES viscosity. Compared with water-based GTE, all DES-based GTEs produced Ag NPs with higher surface plasmon resonance intensities, smaller particle sizes, and narrower distributions. In GTEs derived from non-urea-based DESs, these enhancements were consistent regardless of the water content and HBA mole fraction, suggesting inherent beneficial effects of the DESs. However, urea-based DESs that contained ammonia as a byproduct during DES preparation, exhibited different characteristics: although the geometric sizes of the Ag NPs remained unchanged, increasing water content led to larger hydrodynamic sizes, indicating intensified surface modification of the Ag NPs. The surface modification correlated positively with antioxidant activity, negatively with catalytic activity, and exhibited no significant association with antibacterial activity. Overall, DESs generally enhance the GTE-based biosynthesis of Ag NPs without the need for precise condition optimizations. However, ammonia-generating DESs may require tailored conditions to balance synthesis and activities.

研究了深共晶溶剂（DESs）在促进绿茶提取物（GTE）为基础的银纳米粒子（Ag NPs）生物合成中的作用。评价了四种不同含水量（10 - 50%）和氢键受体（HBA）摩尔分数（0.17-0.83）的DESs。虽然HBA的组成对儿茶素和酚类化合物的提取影响不大，但较高的含水量通常通过降低DES粘度来提高收率。与水基GTE相比，所有基于des的GTE制备的银纳米粒子具有更高的表面等离子体共振强度、更小的粒径和更窄的分布。在非尿素基DESs衍生的gte中，无论含水量和HBA摩尔分数如何，这些增强都是一致的，这表明DESs具有固有的有益作用。然而，在制备过程中含有氨作为副产物的尿素基DES表现出不同的特征：尽管Ag NPs的几何尺寸保持不变，但随着水含量的增加，水动力尺寸增大，表明Ag NPs的表面改性增强。表面修饰与抗氧化活性呈正相关，与催化活性负相关，与抗菌活性无显著相关性。总体而言，DESs通常增强了基于gte的Ag NPs的生物合成，而不需要精确的条件优化。然而，产氨DESs可能需要量身定制的条件来平衡合成和活性。

The hydrodesulfurization (HDS) of heavy gas oil was investigated using NiMo/Al₂O₃ catalysts prepared via two different methods: (i) the conventional impregnation (loading) method, followed by calcination at 500 °C (NiMo-500L), and (ii) an in-situ synthesis approach, with calcination at 500 °C (NiMo-500I) and 700 °C (NiMo-700I). The physicochemical properties of the catalysts were characterized using XRD, BET, TEM, FT-IR, Raman, TGA, H₂-TPR, NH₃-TPD, and XPS techniques. Among the synthesized catalysts, NiMo-500I exhibited the highest HDS activity, achieving 98 % sulfur removal under optimal reaction conditions of 360 °C, LHSV of 1.5 h⁻¹, and a pressure of 4.5 MPa. The superior catalytic performance of NiMo-500I is attributed to its enhanced textural and structural properties, which facilitated the dispersion of active species and improved accessibility of reactants to catalytic sites. A kinetic study of the HDS process revealed activation energy of 26.67 kJ mol⁻¹, with a correlation coefficient (R²) of 0.930, indicating a moderate fit to the kinetic model. The NiMo-500I catalyst shows high stability over 70 h, maintaining approximately 90.8 % HDS efficiency and yielding about 90.3 % heavy gas oil (HGO). These results highlight the potential of in situ-prepared NiMo catalysts, particularly NiMo-500I, as efficient materials for deep desulfurization of heavy gas oil, paving the way for cleaner fuel production.

采用两种不同的方法制备了NiMo/Al2O3催化剂，分别为：(i)传统的浸渍（加载）法，500℃焙烧（NiMo- 500l）和（ii）原位合成法，500℃（NiMo- 500i）和700℃焙烧（NiMo- 700i），研究了重质煤气加氢脱硫（HDS）。采用XRD、BET、TEM、FT-IR、Raman、TGA、H2-TPR、NH3-TPD和XPS等技术对催化剂的理化性质进行了表征。在所合成的催化剂中，NiMo-500I的HDS活性最高，在360°C、1.5 h−1 LHSV、4.5 MPa压力的最佳反应条件下，达到98%的脱硫效果。NiMo-500I优异的催化性能是由于其增强的结构和结构特性，促进了活性物质的分散，提高了反应物对催化位点的接近性。动力学研究表明，HDS过程的活化能为26.67 kJ mol−1，相关系数（R2）为0.930，符合动力学模型。NiMo-500I催化剂在70小时内表现出很高的稳定性，保持约90.8%的HDS效率，产率约90.3%的重质气（HGO）。这些结果突出了原位制备的NiMo催化剂，特别是NiMo- 500i，作为重质柴油深度脱硫的高效材料的潜力，为清洁燃料生产铺平了道路。

Environmental sustainability has become a critical concern in the modern era, necessitating the development of innovative materials for effective water pollution remediation. The introduction of porous materials with high surface area, stability, and tailored properties has become an emerging era in this scenario. This study explores the synthesis of a quercetin-based novel porous organic polymer (QPOP) via Friedel-Crafts alkylation reaction for efficient Rhodamine B dye adsorption. Thus, synthesized QPOP exhibited a high surface area of 1172 m²/g with a pore volume of 1.024 cm³/g and unveiled an exceptional adsorption capacity of 499.52 mg/g for Rhodamine B dye removal. The adsorption process was fitted with the Freundlich isotherm, and the pseudo-second order kinetics model indicates a multilayer chemisorption nature of adsorption. The thermodynamics studies revealed that the adsorption process is spontaneous and endothermic. The mechanism of adsorption was explained by H-bonding, electrostatic and π-π interactions. Furthermore, recyclability studies were assessed for six consecutive cycles with excellent reusability up to 85 % efficiency. The phytotoxicity assessments using mung bean seeds confirmed low toxicity of the treated dye solution. This research contributes to the ongoing efforts to develop advanced materials for environmental remediation and aligns with the global need for clean water solutions.

The development of lightweight, flexible, and multifunctional shielding materials is crucial for mitigating the complex radiation environment in space, comprising high-energy X-rays, protons, and secondary neutrons. In this study, we present a porous composite consisting of polydimethylsiloxane (PDMS), pyridine-functionalized boron nitride nanosheets (Py-BNN), and bismuth iodide (BiI₃) for enhanced multi-radiation shielding. Pyridine functionalization improves BNN dispersion in PDMS by enhancing interfacial compatibility, yielding a more uniform filler network. The porous architecture facilitates uniform BiI₃ adsorption throughout the matrix, thereby enhancing the attenuation of X-rays. Thermal analysis shows an elevated decomposition onset temperature of 504.3 °C for Py-BNN/PDMS, compared to 475.8 °C for BNN/PDMS and 445.7 °C for pure PDMS, indicating enhanced thermal stability from improved filler dispersion. Infrared thermography further confirms improved thermal conductivity. X-ray shielding results reveal the Py-BNN/PDMS/BiI₃ composite exhibits the highest linear attenuation coefficient (4.26 cm⁻¹) and the lowest half-value layer (0.163 cm), outperforming BNN/PDMS/BiI₃ and PDMS/BiI₃. Proton beam tests also show superior attenuation in Py-BNN/PDMS/BiI₃, attributed to the uniform dispersion of Py-BNN in the PDMS porous structures. Overall, the proposed composite achieves lightweight structure, thermal robustness, and effective shielding against multiple radiation types, demonstrating strong potential for next-generation aerospace radiation protection.

开发轻质、灵活和多功能的屏蔽材料对于减轻空间中复杂的辐射环境至关重要，该环境由高能x射线、质子和次级中子组成。在这项研究中，我们提出了一种由聚二甲基硅氧烷（PDMS）、吡啶功能化氮化硼纳米片（Py-BNN）和碘化铋（BiI3）组成的多孔复合材料，用于增强多辐射屏蔽。吡啶功能化通过增强界面相容性改善了BNN在PDMS中的分散，产生了更均匀的填料网络。多孔结构促进了BiI3在整个基体中的均匀吸附，从而增强了x射线的衰减。热分析表明，与BNN/PDMS的475.8°C和纯PDMS的445.7°C相比，Py-BNN/PDMS的分解起始温度提高了504.3°C，这表明填料分散性的改善提高了热稳定性。红外热成像进一步证实了导热性能的改善。x射线屏蔽结果表明，Py-BNN/PDMS/BiI3复合材料的线性衰减系数最高（4.26 cm−1），半值层最低（0.163 cm），优于BNN/PDMS/BiI3和PDMS/BiI3。质子束测试也显示了Py-BNN/PDMS/BiI3中优异的衰减，这归因于Py-BNN在PDMS多孔结构中的均匀分散。总体而言，所提出的复合材料实现了轻量化结构、热稳定性和对多种辐射类型的有效屏蔽，显示出下一代航空航天辐射防护的强大潜力。

Resin-based hard carbon has become an ideal choice for the anode material of sodium-ion batteries due to its tunable microstructure and high sodium storage capacity. However, rational structural modulation to optimize its sodium-ion transport capability and improve its rate performance remains a critical challenge. In this study, a resorcinol–formaldehyde resin precursor was innovatively employed to construct a 3D interconnected spherical hard carbon framework. This structure establishes continuous conductive pathways, significantly enhancing charge transfer kinetics. And particle size variation was achieved through a solvent regulation strategy. Systematic investigations reveal that reducing particle size effectively shortens sodium-ion diffusion distances, leading to enhanced rate capability.

This work presents the removal of arsenic(V) ions from synthetic produced water via hollow fiber supported liquid membrane (HFSLM). The liquid membrane contains N-methyl-N,N,N-trioctylammoniumchloride (Aliquat 336, extractant) and corn oil (solvent). Four stripping solutions i.e. NaOH, HCl, thiourea, and HCl + thiourea are investigated. Optimum conditions found proved to be pH 12 of feed solution, 0.54 M Aliquat 336 in corn oil, and flow rates of 100 mL min-1 for both feed and stripping solution, via response surface methodology (RSM) combined with face centered central composite design (FCCD). Percentages of arsenic extraction and stripping reached 99 % and 100 %, respectively, at 323.2 K. Kinetic studies, thermodynamic parameters, extraction and stripping mechanisms, and mass transfer resistance are analyzed. To enhance liquid membrane stability, the properties of corn oil and the optimal pH demonstrate water resistance capability. New mathematical models, using an integrating factor method, developed to predict the mass transfer of arsenic ions during extraction and stripping, are seen to fit in well with the experimental data and reveal deviations of 6.2 % and 2.8 %, respectively.

Intensive attempts are made to separate sulfur and nitrogen compounds from fossil fuels. Relevantly, phosphonium-based deep eutectic solvents (DESs) have attracted much attention. This study presents results of using an acidic phosphonium-based DES, for desulfurization and denitrogenation from gasoline. The DES components were methyl triphenylphosphonium bromide and para-aminobenzoic acid, molar ratio of 2:3, utilized for extracting thiophene and pyridine from synthetic gasoline, made up of n-hexane, n-heptane, and iso-octane. The liquid–liquid equilibrium was studied at different temperatures, and the crucial distribution coefficient and the separation factor were within (5.9041–11.7793) and (884.61–7285.54) for thiophene; and (9.1867–18.6605) and (939.18–12995.99) for pyridine, respectively. Interestingly, the capability of the DES for thiophene was revealed with more than tenfold enhancement in the separation factor and sevenfold in the distribution coefficient compared with a previously used DES. The NRTL and UNIQUAC thermodynamic models were precisely utilized to simulate the tie-lines and obtain the parameters. Accordingly, a method based on group contributions was employed for determining the thermodynamic parameters. To extend findings to real conditions, Euro 1 gasoline was examined, and the effects of temperature, stirring speed, number of extraction stages and solvent regeneration were evaluated in extracting total sulfur and nitrogen contents.

为了从化石燃料中分离出硫和氮化合物，人们进行了大量的尝试。因此，磷基深共晶溶剂（DESs）受到了广泛的关注。介绍了用酸性磷基DES对汽油进行脱硫脱氮的实验结果。DES组分为甲基三苯基溴化磷和对氨基苯甲酸，摩尔比为2:3，用于从正己烷、正庚烷和异辛烷组成的合成汽油中提取噻吩和吡啶。研究了不同温度下的液液平衡，噻吩的临界分布系数和分离系数分别在5.9041 ~ 11.7793和884.61 ~ 7285.54之间；吡啶为（9.1867 ~ 18.6605）和（939.18 ~ 12995.99）。有趣的是，与以前使用的DES相比，DES对噻吩的分离系数提高了10倍以上，分配系数提高了7倍。利用NRTL和UNIQUAC热力学模型精确地模拟了连接线并获得了参数。因此，采用基于基团贡献的方法确定热力学参数。为了将研究结果推广到实际条件下，研究了欧1汽油，并评估了温度、搅拌速度、提取阶段数和溶剂再生对提取总硫和总氮含量的影响。

An ice-phobic polyurethane (PU) coating from castor oil, modified with 3-aminopropyltriethoxysilane, has been developed. The castor oil-derived silanized polyurethane prepolymer (PreCOPU-Si) was synthesized using controlled reactions and characterized through advanced techniques, in comparison to the unsilanized prepolymer (PreCOPU). Moisture-cured coatings (COPU-Si and COPU) showed successful silane group incorporation. Ice adhesion tests revealed significantly reduced adhesion strength for COPU-Si: 0.2 MPa (normal tension) and 0.05 MPa (shear tension), compared to unmodified COPU (1.2 MPa and 0.17 MPa). Enhanced hydrophobicity was confirmed via water contact angle measurements and freezing studies, demonstrating reduced ice adhesion and stable droplet shapes. COPU-Si exhibited improved mechanical properties and strong adhesion (>10 MPa) to fiberglass (FG), positioning this castor oil-derived silanized polyurethane coating as a sustainable, high-performance solution for ice-phobic applications.

以蓖麻油为原料，经3-氨基丙基三乙氧基硅烷改性，制备了一种疏冰聚氨酯（PU）涂料。通过控制反应合成了蓖麻油基硅化聚氨酯预聚物（PreCOPU- si），并通过先进的技术对其进行了表征，与非硅化预聚物（PreCOPU）进行了比较。湿固化涂层（COPU- si和COPU）成功地加入了硅烷基团。冰粘附试验显示，与未改性COPU （1.2 MPa和0.17 MPa）相比，COPU- si的粘附强度显著降低，分别为0.2 MPa（正张力）和0.05 MPa（剪切张力）。通过水接触角测量和冷冻研究证实了疏水性的增强，表明冰粘附性降低，液滴形状稳定。COPU-Si表现出更好的机械性能和与玻璃纤维（FG）的强附着力（>10 MPa），将这种蓖麻油衍生的硅烷化聚氨酯涂层定位为一种可持续的、高性能的疏冰应用解决方案。
