Zinc oxide (ZnO) is a non-toxic semiconductor known for its broad optical band gap and versatility in industrial and medical applications. This study explores the electrochemical properties of pure ZnO modified by making its composite with Y₂O₃. Three composite samples were prepared by adding 2 %, 5 %, and 8 % Y₂O₃ in pure ZnO. X-ray diffraction was used to characterize each sample for phase and structural investigation. The ZnO sample is found in its pure hexagonal phase, while the composites exhibit phases of both ZnO and Y₂O₃. Crystallite size calculations from XRD indicated that all samples are bulk in nature. Galvanostatic charging and discharging (GCD) curves at varying current densities, electrochemical impedance spectroscopy (EIS), and cyclic voltammetric study (CV) at various scan rates were used to investigate the electrochemical characteristics. CV plots of all samples show clear redox peaks and changes in capacitance with scan rate. The charge storage mechanism in all samples involves a mixture of double-layer capacitance and pseudocapacitive behaviour. According to the GCD curve, composites have higher specific capacitance than pure ZnO. The specific capacitance rises from 277 F/g to 449 F/g as the Y₂O₃ concentration is increased from 2 % to 5 % at a current density of 2A/g and for 8 % Y₂O₃ it becomes 467 F/g. Lower charge transfer resistance is demonstrated by ZnO after incorporation of 5 % and 8 % Y₂O₃, suggesting improved electrochemical stability and enhanced performance for supercapacitor applications.

氧化锌（ZnO）是一种无毒半导体，以其宽光学带隙和多功能性而闻名于工业和医疗应用。研究了用Y2O3对纯ZnO进行复合改性后的电化学性能。在纯ZnO中分别添加2%、5%和8%的Y2O3制备了3种复合样品。采用x射线衍射对样品进行物相和结构表征。ZnO样品为纯六方相，而复合材料同时具有ZnO和Y2O3相。XRD计算表明，所有样品均为块状。采用不同电流密度下的恒流充放电（GCD）曲线、不同扫描速率下的电化学阻抗谱（EIS）和循环伏安法（CV）研究了其电化学特性。所有样品的CV图均显示出清晰的氧化还原峰和电容随扫描速率的变化。所有样品中的电荷存储机制都涉及双层电容和伪电容行为的混合。根据GCD曲线，复合材料比ZnO具有更高的比电容。当电流密度为2A/g时，当Y2O3浓度从2%增加到5%时，比电容从277 F/g增加到449 F/g，当Y2O3浓度为8%时，比电容变为467 F/g。在ZnO中掺入5%和8%的Y2O3后，ZnO的电荷转移电阻降低，表明其电化学稳定性得到改善，超级电容器的性能得到增强。

The reported present work, eco-friendly green synthesis of multifunctional silver nanoparticles (Ag NPs) was carried out from silver ions using the aqueous extract of fresh Muntingia calabura fruits, and their biological and photocatalytic potentials was subsequently evaluated. The aqueous extract was initially analyzed to identify the presence/absence of primary phytochemicals. Silver ions were treated with the extract, and the successful synthesis of Ag NPs shows confirmed by the appearance of a surface Plasmon resonance (SPR) peak at 428 nm, as observed through UV–Vis spectrophotometry. The secondary oxidized flavonoids that serve as the capping and reducing agent of the built Ag NPs have been identified by preliminary phytochemical and FT-IR studies. High-resolution transmission electron microscopy (HRTEM) revealed that the Ag NPs were spherical in shape, with sizes ranging from approximately 5 to 30 nm.In-vitro tests of the synthesized Ag NPs shows the anticancer, antibacterial, and antioxidant properties revealed that they may be effective against traditional medicines. Using the MTT assay, the Ag NPs also showed cytotoxicity against the human pancreatic cancer cell line PANC-1 cells. According to the MTT assay, the IC₅₀ values for Ag NPs were 189 ± 2.32 μg/ml compare with the negative control untreated cells.Ag NPs was demonstrated outstanding photocatalytic activity, degrading the environmentally degraded Basic Fuchsin dye in 30 min. This one-step, eco-friendly synthesis of Ag NPs ispresents a novel alternative to conventional chemical methods and holds potential applications in modern nanoscience and technology.

This study successfully synthesized and characterized CuS, ZnS, and CuS/ZnS composite nanoparticles with varying component ratios. EDX analysis and elemental mapping confirmed the formation of the CuS/ZnS composite, showing characteristic peaks for copper (Cu), zinc (Zn), and sulfur (S). The resulting heterostructures, particularly the 1:1 CuS:ZnS composite, exhibited significantly enhanced visible-light photocatalytic activity. This composite achieved a 90 % degradation efficiency of methylene blue dye in 85 min, with a pseudo-first-order rate constant (K_app) of 0.02173 min^-1, which is substantially higher than that of the individual CuS and ZnS components. CuS nanoparticles demonstrated superior visible-light photocatalytic activity compared to ZnS, which was expected given their respective bandgaps. Scavenger experiments identified holes (h⁺) as the dominant reactive species. The catalyst's reusability was confirmed over three cycles, demonstrating its stability for potential wastewater treatment applications.

Triazole-based Metal-Organic Frameworks (Tz-MOFs) are a special type of material that combines the triazole ligands with the MOFs. These frameworks are made by linking metal ions or clusters with nitrogen-rich triazole derivatives that can bind in different ways. They work better for storing and separating gases, especially for capturing CO₂ and storing hydrogen, because they have a larger surface area and can selectively adsorb. Triazole ligands work well with metal centers, which makes them better at catalyzing reactions. This makes them useful for electrocatalysis, photocatalysis, and organic transformations. These MOFs are good chemical sensors because they can easily and accurately find biomolecules, heavy metals, and toxic gases. Tz-MOF's controlled release property and biocompatibility make them promising for drug delivery in biomedical applications. Their potential in healthcare is further enhanced by their antimicrobial activity. The focus of recent advancements is on improving their operational stability, scalability, and functionalization for practical applications. These materials offer a cutting-edge platform for tackling significant issues in environmental sustainability, medicine, and energy storage. This review presents a comprehensive analysis of Tz-MOFs, emphasizing their structural diversity and applications. These MOFs are ideal for a range of applications due to their structures, adjustable porosity, and excellent thermal stability.

三唑基金属有机骨架（Tz-MOFs）是一种结合了三唑配体和mfs的特殊材料。这些框架是通过将金属离子或簇与可以以不同方式结合的富氮三唑衍生物连接而成的。它们更适合储存和分离气体，特别是捕获二氧化碳和储存氢气，因为它们有更大的表面积，可以选择性地吸附。三唑配体能很好地与金属中心配合，这使得它们能更好地催化反应。这使得它们对电催化、光催化和有机转化很有用。这些mof是很好的化学传感器，因为它们可以轻松准确地发现生物分子、重金属和有毒气体。z- mof的控释特性和生物相容性使其在生物医学领域具有广阔的应用前景。它们的抗菌活性进一步增强了它们在医疗保健方面的潜力。最近进展的重点是提高它们的操作稳定性、可伸缩性和实际应用的功能化。这些材料为解决环境可持续性、医学和能源储存方面的重大问题提供了一个前沿平台。本文对tz - mof进行了全面的分析，重点介绍了它们的结构多样性和应用。由于其结构，可调节的孔隙率和优异的热稳定性，这些mof是一系列应用的理想选择。

Novel crystallographic investigation of sol-gel-derived anatase TiO₂ nanocrystals synthesized using tetra isopropyl orthotitanate (TIOT) as a precursor at pH 9.0 for hydrolysis promoter. Unlike conventional methods integrated whole powder pattern fitting (WPPF) based Rietveld refinement to quantitatively analyze the crystal structure, phase purity and microstructural features of the synthesized nanoparticles (NPs). The refinement confirmed the formation of 100 % pure anatase phase with a tetragonal structural shape [a=b= 3.7893 Å, c= 9.492 Å]. Notably, the study employed seven different crystallite size determination identical models where Scherrer method estimating an average size of 8.87 nm. The calculated unit cell volume (136.287 Å³), lattice strain (0.76 %), microstrain (0.00312), crystallinity (61.399 %), crystallinity index (1.44) and dislocation density (0.0127 nm⁻²) indicated lattice expansion and high defect tolerance critical features for catalytic and electronic applications. Peak profiling showed highest preferred orientation along the (101) plane at 2θ= 25.289°, with a d-spacing of 0.35190 nm and an intensity of 6542 cps. SEM confirmed uniformly dispersed, non-agglomerated NPs, while EDS analysis validated elemental purity with 60 % Ti and 40 % O. This comprehensive structural and surface morphological analysis, combining simple synthesis with advanced refinement, provides a reliable framework for optimizing TiO₂ nanocrystals in functional applications.

以正钛酸四异丙酯（TIOT）为前驱体，pH为9.0，水解促进剂合成溶胶-凝胶型锐钛矿型TiO2纳米晶的晶体学研究。与传统方法不同，采用基于Rietveld精细化的全粉末模式拟合（WPPF）方法对合成的纳米颗粒（NPs）的晶体结构、相纯度和微观结构特征进行了定量分析。细化证实形成100%纯锐钛矿相，结构形状为四方[a=b= 3.7893 Å， c= 9.492 Å]。值得注意的是，该研究采用了7种不同的晶体尺寸测定相同的模型，其中Scherrer法估计的平均尺寸为8.87 nm。计算得到的晶胞体积（136.287 Å3）、晶格应变（0.76%）、微应变（0.00312）、结晶度（61.399 %）、结晶度指数（1.44）和位错密度（0.0127 nm−2）表明晶格膨胀和高缺陷容错性是催化和电子应用的关键特征。峰谱分析显示，在（101）面2θ= 25.289°处，光强为6542 cps， d-间距为0.35190 nm。SEM证实了纳米TiO2均匀分散、无团聚，而EDS分析证实了元素纯度分别为60% Ti和40% o。这种综合的结构和表面形态分析，结合了简单的合成和先进的细化，为优化功能应用中的TiO2纳米晶体提供了可靠的框架。

This study is focused on the design and photovoltaic performance analysis of lead (Pb) based perovskite solar cell using Solar Cell Capacitance Simulator (SCAPS). Perovskite materials display high power conversion efficiency and cheap manufacturing costs. This makes them an exciting candidate for the application in renewable energy technology. This work is focused on the construction and design of perovskite solar cell by introducing TiO₂ as electron transporting layer (ETL) and PEDOT:PSS as hole transporting layer (HTL). The device structure for the simulation is Au/PEDOT:PSS/CH₃NH₃PbI₃/TiO₂/ITO. Numerical simulation on photovoltaic parameters such as open circuit voltage (V_OC), short circuit current density (J_SC), fill factor (FF), and power conversion efficiency (PCE), as well as short-circuit current density versus voltage (J-V) characteristics, have been studied. The consequences of doping concentration, absorber layer thickness, electron affinity of absorber layer, thickness of ETL, and HTL on photovoltaic performance have been investigated. The simulated perovskite solar cell offers an efficiency of 23.10%, an open circuit voltage (V_OC) of 1.093 V, and a short-circuit current density (J_SC) of 24.634 mA/cm². The optimum thickness of the absorber layer, HTL, and ETL layer has also been calculated for better power conversion efficiency of the device.

Rare earth-doped ferrites stems from their unique and tuneable properties, leading to a wide range of potential applications. Synthesis of CoFe_2-xNd_xO₄:SiO₂ nanocomposites at various concentrations of Nd³⁺ ions doping is carried out by sol-gel method and structural as well as thermal parameters have been evaluated by using XRD, FTIR, TEM, and TGA- DTG analysis techniques. Enhancement in XRD peak intensity may be due to an increase in crystallite size which could be attributed to the larger ionic radius of Nd³⁺ (0.995 Å) replacing Fe³⁺ ions (0.67 Å). TEM results are also reported in good agreement for particle size 26 nm, 35 nm, 39 nm, and 47 nm at Nd³⁺ ions concentrations 0.00, 0.050, 0.075, and 0.1 respectively, supporting the XRD results. TGA- DTG curve indicates a maximum weight loss for all the samples in the temperature range of 20 °C–350 °C due to maximum water evaporation and decomposition of precursors. At high temperatures, spherical particles with aggregation can be viewed from the TEM images. These explored physicochemical and morphological parameters may be insightful to optimise novel functionalities for advance high-tech fields.

稀土掺杂铁氧体由于其独特的可调谐特性，具有广泛的潜在应用前景。采用溶胶-凝胶法合成了不同浓度掺杂Nd3+离子的CoFe2-xNdxO4:SiO2纳米复合材料，并利用XRD、FTIR、TEM和TGA- DTG分析技术对其结构和热参数进行了评价。XRD峰强度的增强可能是由于晶体尺寸的增大，这可能是由于Nd3+ （0.995 Å）取代Fe3+离子（0.67 Å）的离子半径增大所致。在Nd3+浓度分别为0.00、0.050、0.075和0.1时，TEM结果与XRD结果一致，表明粒径分别为26 nm、35 nm、39 nm和47 nm。TGA- DTG曲线表明，在20°C - 350°C温度范围内，由于前驱体的最大水分蒸发和分解，所有样品的重量损失最大。在高温下，透射电镜图像可以观察到球状颗粒聚集。这些探索的物理化学和形态参数可能有助于优化先进高科技领域的新功能。
