The exact manipulation of the interfacial electric field is a crucial aspect in enhancing the electromagnetic wave absorption efficiency during the manufacturing of optimized and adjustable absorbers. Furthermore, achieving superior electromagnetic wave absorption necessitates the synergistic interaction between commencing various loss mechanisms and maintaining appropriate impedance matching. This work utilizes in-situ solvothermal synthesis to deposit Ni-ferrite nano-powder onto silver nanowire surfaces with Schottky contact, while simultaneously producing Rice Husk-Derived Carbon Powder by a simple pyrolysis process, to create a novel double-layer absorber. The dual-layer absorber optimizes the interaction between various attenuation techniques and impedance matching by establishing widely used heterointerfaces and diverse energy level arrangements. The design optimization of the two-layer absorber, specifically through the modification of each layer’s thickness, yielded an absorption bandwidth encompassing the entire examined frequency range, with a minimum reflection coefficient of −50.1 dB attained at 14.6 GHz for an overall thickness of 1.2 mm. The findings reveal that the plentiful heterogeneous interfaces and multiple polarization centers in the double-layer absorber, combined with the Mott-Schottky heterointerface in Ag/Ni-ferrite nanowires, markedly accelerate electron migration, facilitating the development of built-in electric fields (BIEFs) and improving dielectric loss, polarization relaxation characteristics, and magnetic loss.

在优化可调吸波器的制造过程中，界面电场的精确控制是提高电磁波吸收效率的关键。此外，实现优异的电磁波吸收需要启动各种损耗机制和保持适当的阻抗匹配之间的协同作用。本研究利用原位溶剂热合成技术将镍铁氧体纳米粉末沉积在具有肖特基接触的银纳米线表面，同时通过简单的热解工艺生产稻壳衍生碳粉，以创建一种新型的双层吸收剂。双层吸收器通过建立广泛使用的异质界面和不同的能级排列，优化了各种衰减技术之间的相互作用和阻抗匹配。两层吸收器的设计优化，特别是通过修改每层的厚度，产生了包含整个检测频率范围的吸收带宽，在14.6 GHz时，总厚度为1.2 mm，反射系数最小为- 50.1 dB。研究结果表明，双层吸收层中丰富的非均相界面和多个极化中心，结合Ag/ ni -铁氧体纳米线中的Mott-Schottky异质界面，显著加速了电子迁移，促进了内置电场（BIEFs）的发展，改善了介电损耗、极化弛豫特性和磁损耗。

In this study, we present a microwave-assisted synthesis to produce NiO, MWCNT@NiO, and rGO@NiO hybrid nanostructures efficiently. Comprehensive characterizations, including XRD, FTIR, FESEM, TEM, EDX, and BET confirmed the formation and structural integrity of MWCNT@NiO and rGO@NiO nanostructures. The nanostructures’ electrochemical efficiency was examined in a 2 M KOH electrolyte. The specific capacitance of the rGO@NiO nanostructure is found to be the highest, with 491F/g at a current density of 1 A/g, compared to pure NiO (255F/g) and MWCNT@NiO (370F/g). This greater performance comes from the collaborative properties of the reduced graphene oxide, providing better ion diffusion, charge transfer efficiency, and active surface area with exemplary stability of capacitance of 91 % after 5000 cycles, which is much better cycling and mechanical stability than that of MWCNT@NiO and pure NiO. Furthermore, the electrochemical performance of the rGO@NiO ASC device was assessed using 1 M KOH as the electrolyte throughout a potential range of 0 to 1.2 V. At a current density of 1A/g, the device provided 31.92 Wh/kg energy density and 599.96 W/kg power density. The ASC device demonstrated good charge–discharge behavior, indicating superior capacitance properties and efficient ion transport. Thus, the rGO@NiO hybrid nanostructure can be a potential material for supercapacitor applications.

在这项研究中，我们提出了一种微波辅助合成方法来高效地制备NiO， MWCNT@NiO和rGO@NiO杂化纳米结构。通过XRD、FTIR、FESEM、TEM、EDX和BET等综合表征，证实了MWCNT@NiO和rGO@NiO纳米结构的形成和结构完整性。在2 M KOH电解液中考察了纳米结构的电化学效率。与纯NiO （255F/g）和MWCNT@NiO （370F/g）相比，rGO@NiO纳米结构的比电容最高，在电流密度为1 a /g时为491F/g。这种更好的性能来自于还原氧化石墨烯的协同特性，提供更好的离子扩散、电荷转移效率和活性表面积，在5000次循环后电容稳定性为91%，这比MWCNT@NiO和纯NiO的循环和机械稳定性要好得多。此外，在0 ~ 1.2 V电位范围内，以1 M KOH作为电解液，对rGO@NiO ASC器件的电化学性能进行了评估。在1A/g电流密度下，器件的能量密度为31.92 Wh/kg，功率密度为599.96 W/kg。ASC器件表现出良好的充放电性能，显示出优越的电容性能和高效的离子传输。因此，rGO@NiO混合纳米结构可以成为超级电容器应用的潜在材料。

This study develops a NiFe-LDH@ZIF-67 composite for efficient co-adsorption of methyl green (MG, 239.05 mg/g) and oxytetracycline (OTC, 147.39 mg/g) in various water matrices. Comprehensive characterization (FTIR, SEM-EDS, XRD, XPS, TGA) confirmed the material’s structural integrity. Adsorption followed pseudo-second-order kinetics (R² > 0.98) and Langmuir isotherms, with MG showing higher affinity due to stronger electrostatic and π-π interactions. Real-water tests demonstrated superior performance in tap water (231.34 mg/g) versus lake water (209.61 mg/g), with faster kinetics (α = 899.501 vs 485.279). The composite exhibited excellent reusability (>95 % efficiency after 5 cycles) and stability post-regeneration. Computational studies revealed binding energies of −1.54 eV (MG) and −1.21 eV (OTC), with hydrogen bonding (N/OH···O) driving preferential adsorption of MG. An optimized ANN model predicted optimal conditions (pH 6, 40 °C) with < 5 % error, facilitating industrial scale-up. The work combines experimental validation with multiscale simulations (DFT/Monte Carlo) to establish structure–property relationships, while machine learning enables process optimization. This integrated approach advances the design of hybrid adsorbents for practical water treatment applications, addressing key challenges of selectivity and stability in complex wastewater systems. The study provides both fundamental insights into adsorption mechanisms and a practical framework for developing efficient, reusable materials for multi-pollutant removal.

本研究开发了一种NiFe-LDH@ZIF-67复合材料，用于在各种水基质中高效共吸附甲基绿（MG, 239.05 MG /g）和土霉素（OTC, 147.39 MG /g）。综合表征（FTIR, SEM-EDS， XRD， XPS， TGA）证实了材料的结构完整性。吸附遵循拟二级动力学（R2 > 0.98）和Langmuir等温线，MG由于更强的静电和π-π相互作用而表现出更高的亲和力。自来水（231.34 mg/g）比湖水（209.61 mg/g）具有更好的性能，且动力学更快（α = 899.501 vs 485.279）。复合材料具有良好的可重复使用性（5次循环后效率达95%）和再生后的稳定性。计算结果表明，MG的结合能为- 1.54 eV （MG）和- 1.21 eV (OTC)，氢键（N/OH··O）驱动MG的优先吸附。优化的人工神经网络模型预测了最佳条件（pH值6,40°C），误差为<； 5%，有利于工业规模扩大。这项工作将实验验证与多尺度模拟（DFT/蒙特卡罗）相结合，以建立结构-属性关系，而机器学习可以实现过程优化。这种综合方法推进了混合吸附剂在实际水处理应用中的设计，解决了复杂废水系统中选择性和稳定性的关键挑战。该研究提供了对吸附机制的基本见解，并为开发高效、可重复使用的多污染物去除材料提供了实用框架。

Increasing carbon dioxide (CO₂) emissions on a global scale necessitate the development of effective and sustainable solutions to combat climate change. This study examined in detail the CO₂ adsorption capacity and regeneration performance of the nanographene@zinc oxide (NG@ZnO-green) nanocomposite, produced using an environmentally friendly green synthesis method. While pure water was used as the solvent in the impregnation stage of the conventional production of the NG@ZnO nanocomposite, hemp stalk bio-extract was used instead in the green synthesis process. This bio-extract enabled more effective binding of ZnO to the NG surface, thus maximizing the interaction between NG and ZnO, resulting in a more homogeneous modification. SEM and TEM analyses revealed that the ZnO particles were densely and uniformly distributed on the NG surface. According to BET results, the NG@ZnO-green nanocomposite has a specific surface area of 705 m²/g, a total pore volume of 0.51 cm³/g, and a mean pore diameter of 4.97 nm. CO₂ adsorption tests were conducted at 298 K and 273 K under 1 bar pressure, and NG, NG@ZnO, and NG@ZnO-green exhibited CO₂ uptake capacities of 2.07–2.59 mmol/g, 4.56–5.43 mmol/g, and 5.95–6.99 mmol/g, respectively. This comparison revealed that the NG@ZnO-green nanocomposite exhibited significantly superior performance compared to both pure NG and conventionally synthesized NG@ZnO, confirming the effectiveness of the proposed green synthesis strategy. The isosteric heat of adsorption (Q_st), calculated using the Clausius–Clapeyron equation, indicated strong physical interactions between NG@ZnO-green and CO₂. Ten-cycle reuse tests revealed a high regeneration capacity for this nanocomposite, with a reuse efficiency of up to 95 %. All findings demonstrate that the environmentally friendly synthesis method developed using hemp-based bio-extract offers advantages not only in terms of sustainability but also in terms of CO₂ capture performance. Furthermore, this capacity exceeds that reported for many advanced adsorbents under similar conditions, demonstrating the material’s technical and environmental superiority. The NG@ZnO-green nanocomposite stands out as a promising candidate for carbon capture technologies.

全球范围内二氧化碳排放量的增加要求制定有效和可持续的解决方案来应对气候变化。本研究详细考察了采用环保绿色合成方法制备的nanographene@zinc氧化物（NG@ZnO-green）纳米复合材料的CO2吸附能力和再生性能。传统生产NG@ZnO纳米复合材料的浸渍阶段采用纯水作为溶剂，绿色合成过程中采用大麻茎生物提取物代替。该生物提取物能够更有效地将ZnO结合到NG表面，从而使NG和ZnO之间的相互作用最大化，从而获得更均匀的修饰。SEM和TEM分析表明，ZnO颗粒密集均匀地分布在NG表面。BET结果表明，NG@ZnO-green纳米复合材料的比表面积为705 m2/g，总孔容为0.51 cm3/g，平均孔径为4.97 nm。在298 K和273 K、1 bar压力下进行CO2吸附实验，结果表明，NG、NG@ZnO和NG@ZnO-green对CO2的吸收能力分别为2.07 ~ 2.59 mmol/g、4.56 ~ 5.43 mmol/g和5.95 ~ 6.99 mmol/g。通过比较发现，NG@ZnO-green纳米复合材料的性能明显优于纯NG和常规合成NG@ZnO，证实了所提出的绿色合成策略的有效性。利用Clausius-Clapeyron方程计算的等等吸附热（Qst）表明NG@ZnO-green与CO2之间存在很强的物理相互作用。十循环重复使用试验表明，这种纳米复合材料具有很高的再生能力，重复使用效率高达95%。所有研究结果都表明，使用基于大麻的生物提取物开发的环境友好型合成方法不仅在可持续性方面具有优势，而且在二氧化碳捕获性能方面也具有优势。此外，在类似条件下，这种能力超过了许多先进吸附剂的报道，证明了该材料的技术和环境优势。NG@ZnO-green纳米复合材料作为碳捕获技术的一个有前途的候选者脱颖而出。

Study on the combustion characteristics of lithium-ion battery vent gases are vital to prevent and mitigate lithium-ion battery thermal runaway incidents. A skeletal mechanism is developed for the combustion of lithium-ion battery vent gases, in order to increase accuracy and reduce computational time of Computational Fluid Dynamics simulation. Initially, a detailed chemical kinetic model covering C₀-C₂ small-molecule gases, hydrofluorocarbons, and four typical electrolytes in lithium-ion battery discharge gases was developed. The accuracy of the detailed chemical reaction mechanism is validated by the experimental data of laminar flame velocities and ignition delay time of lithium-ion battery vent gases. Subsequently, the detailed mechanism (226 species, 1656 reactions) was reduced to a minimal skeletal mechanism (66 species, 507 reactions). The minimal skeletal mechanism is validated by the ignition delay time, laminar burning velocity, key species concentrations and extinction limits of three typical lithium-ion battery vent gases in varied conditions.

The corrosion continues to be a pervasive and acute challenge across industries, triggering severe economic leverages exceeding US $2.5 trillion annually. In the quest to cope up with the sustainable goals there has been active research delving into high-performance, and eco-conscious corrosion mitigation strategies. In this regard, graphitic carbon nitride (g-C₃N₄)-based coordinated composites have emerged as a transformative class of materials. To unravel the state-of-the-art for g-C₃N₄-based coordinated composites, this review expounds upon the multifaceted advancements in these g-C₃N₄-coordinated systems tailored for corrosion inhibition applications. Through an integrated and in-depth analysis, the review addresses the g-C₃N₄′s unique electronic configuration, tunable nitrogen-rich framework and its ability to coordinate with metal ions, nanostructures, and functional moieties to yield superior protective coatings. Electrochemical and gravimetric analyses reveal the corrosion mitigation efficacies surpassing over 95 % with the R_ct values of over 10⁶ Ω.cm². The discussion further delineates the role of g-C₃N₄ in altering the charge-transfer dynamics and interfacial electron behaviour, specifically under light-assisted or photoelectrochemical ambient. This review culminates with a pioneering perspective on contemporary challenges, scalability bottlenecks, along with futuristic trends shaping the industrial transition of g-C₃N₄-based corrosion inhibitors, underscoring their potential as next-generation intelligent coating materials in corrosion science.

The composition and properties of raw materials significantly influence the preparation of spinnable mesophase pitch. This study examined the effects of varying anthracene oil (AN-oil) proportions on mesophase pitch produced through preliminary and advanced polymerization, and the resultant carbon fibers. Results showed that an optimal AN-oil addition promoted pitch dehydrogenation and polymerization, enhancing the ordered stacking of polycyclic aromatic hydrocarbons. Advanced polymerization led to a progressive increase in pitch’s C/H ratio (from 1.84 to 1.96), thermal stability, f_a, mesophase content (from 79 to 98 %), and mesophase domain size, while the hydrogen content in aliphatic and cyclic structures gradually decreased. In carbon fibers derived from preliminary polymerization, spherical protrusions and depressions were observed on the cross-section due to stress-induced detachment of mesocarbon microbeads. Appropriate AN-oil addition improved the ordered crystalline structure of mesophase pitch, optimizing the microstructure and properties of the as-prepared carbon fibers. With increasing AN-oil content in advanced polymerization, the cross-sectional morphology of carbon fibers evolved from a “skin-core” or “turbulent layer” structure to a more ordered “radial” arrangement. Notably, carbon fibers produced via advanced polymerization with 20 wt% AN-oil exhibited superior tensile strength (1209 MPa) and modulus (193 GPa).

原料的组成和性能对可纺中间相沥青的制备有重要影响。本研究考察了不同比例的蒽油（AN-oil）对初级聚合和高级聚合中间相沥青以及所得碳纤维的影响。结果表明，最佳an -oil的加入促进了沥青的脱氢和聚合，增强了多环芳烃的有序堆积。超前聚合导致沥青的C/H比（从1.84增加到1.96）、热稳定性、fa、中间相含量（从79增加到98%）和中间相畴尺寸逐渐增加，而脂肪族和环结构中的氢含量逐渐减少。在初步聚合得到的碳纤维中，由于应力诱导的中碳微珠脱落，在截面上观察到球形突起和凹陷。适量AN-oil的加入改善了中间相沥青的有序结晶结构，优化了碳纤维的微观结构和性能。随着高级聚合中AN-oil含量的增加，碳纤维的横截面形态从“皮核”或“湍流层”结构演变为更有序的“径向”结构。值得注意的是，通过添加20 wt% AN-oil的高级聚合生产的碳纤维具有优异的抗拉强度（1209 MPa）和模量（193 GPa）。
