The phase-pure nanocrystalline FeWO₄ ferberite structure was synthesized through hydrothermal method. The prepared FeWO₄ nanorod was characterized through X-ray diffraction (XRD) with Rietveld refinement, Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), UV-Vis diffuse reflectance spectroscopy, dynamic light scattering (DLS), and scanning electron microscopy (SEM). XRD analysis indicated the formation of monoclinic ferberite FeWO₄ nanocrystals with most intense peak (

Different size and strain broadening method was utilized to know crystallite size. An average crystallite size of 22.20 nm was obtained from Debye-Scherrer equation. Rietveld refinement confirms 100 % monoclinic ferberite phase purity with 49.27 % crystallinity. The prepared FeWO₄ exhibited a lattice volume of 134.281 Å³ with a minor crystal strain of 0.04 %, indicating good structural stability. SEM image revealed uniform nanorod morphology with an average diameter of 33.29 nm. Reflectance spectra showed strong light absorption (82–88 %) over 300–850 nm and the Kubelka-Munk plot demonstrated a band gap of 2.27 eV. Despite a near-neutral zeta potential (−0.9 mV), a monodispersed colloidal system was observed. The synthesized FeWO₄ exhibited excellent removal efficiency, achieving 95.46 ± 0.41 % Methylene Blue(MB) adsorption in 60 min. The observations demonstrate that the synthesized ferberite FeWO₄ possesses optimized structural stability, optical, and surface properties that make it a strong candidate for environmental remediation and advanced materials applications.

Transparent conductors based on silver nanowires (AgNWs) combine high transmittance with low sheet resistance. These properties, however, depend strongly on the fabrication method, which determines the films structural and morphological features. Here we comparatively analyze AgNW transparent conductors fabricated by ultrasonic spray coating and spin coating for use in thin transparent heaters. We assess heater homogeneity via the average temperature, the fraction of the area within a narrow band of the maximum temperature, and a weighted uniformity coefficient (UC^w). For a spray-coated heater with a transmittance of ∼80 % and a sheet resistance of 11 Ω/sq, the maximum temperature reached 173 °C at 9 V, whereas the spin-coated counterpart was limited to 122 °C. We also demonstrate de-icing using a highly transparent flexible spray-coated conductor. These results highlight the critical role of the fabrication route for AgNW-based (and other nanomaterial-based) transparent conductors in flexible electronics.

基于银纳米线（AgNWs）的透明导体结合了高透射率和低片电阻。然而，这些性能在很大程度上取决于制备方法，这决定了薄膜的结构和形态特征。本文比较分析了超声波喷涂和旋转喷涂制备的AgNW透明导体在薄透明加热器中的应用。我们通过平均温度、最高温度窄带内面积的比例和加权均匀系数（UCw）来评估加热器的均匀性。对于透过率为~ 80 %，片电阻为11 Ω/sq的喷涂加热器，在9 V时最高温度可达173°C，而旋转涂层加热器的最高温度限制在122°C。我们还演示了使用高度透明的柔性喷涂导体除冰。这些结果突出了基于agnw（和其他基于纳米材料）的透明导体在柔性电子产品中的制造路线的关键作用。

Beyond skincare, the expanding roles of nanomaterials in oral care, haircare (washing, treatment, and dyeing), decorative cosmetics, and nail care are discussed to highlight their versatility. The advantages of nanotechnology, including solubilization of poorly soluble actives, improved chemical stability, and reduced production time, are carefully weighed against pressing challenges such as toxicity concerns, environmental release, ethical implications, and regulatory limitations. The review emphasizes the importance of safe-by-design strategies, risk assessment frameworks, and consumer trust in advancing the responsible adoption of nanocosmetics. Looking ahead, future directions point toward the integration of sustainable practices, eco-friendly nanomaterials, and circular economy approaches to address environmental and societal expectations. Collectively, this review article provides an updated perspective on the potential, limitations, and sustainable pathways of nanotechnology in shaping next-generation cosmetic innovations.

Energy production and storage systems are of prime importance for both scientific research and end-users, given the urgent need to reduce environmental and climatic impacts associated with conventional energy technologies. Energy storage plays a key role in managing the balance between supply and demand, while mitigating the intermittency of renewable energy sources. The development of these systems is therefore essential if we are to meet today’s energy challenges. With this in mind, advanced materials stand out as promising solutions for applications in solar cells and storage systems. These materials offer significant advantages, such as lower production costs and enhanced efficiency. Their abundance in Earth’s crust and their non-toxicity reinforce their relevance for sustainable and environmentally friendly solutions. This review provides a comprehensive analysis of solar cell technologies and the fundamentals of energy storage systems, with a particular focus on the convergence of materials engineering and storage strategies. Special attention is devoted to thin films, including two-dimensional transition metal dichalcogenides, metal oxides, and emerging alternative thin films, highlighting their roles in improving charge transport, stability, and overall device performance. The integration of these materials into alternative energy storage systems is also discussed, underscoring their capacity to combine high efficiency with environmental compatibility. The findings reveal both the opportunities and limitations of thin films in advancing solar energy conversion and energy storage. While remarkable progress has been achieved in terms of efficiency and stability, challenges such as large-scale integration, cost reduction, and long-term durability remain critical. Finally, the review emphasizes future directions, pointing to the need for multidisciplinary approaches and the exploration of novel material combinations to enable the next generation of sustainable energy systems.

The development of three-dimensional nanowire structures made from magnetic materials is a promising area of research for next-generation information storage technologies. Advanced synthetic methodologies have enabled the fabrication of highly ordered arrays of magnetic nanowires, significantly enhancing data recording densities. The fundamental mechanism of writing and reading data in such devices relies on the magnetization reversal process. However, magnetostatic interactions between individual nanowires can present challenges for reliable data storage. This study investigates how geometric parameters influence the magnetic properties of nanowires. Specifically, it examines segmented configurations with alternating magnetic/nonmagnetic layers, as well as non-segmented structures composed solely of magnetic material. Using first-order reversal curve analysis, we systematically explore how varying the aspect ratio (diameter-to-length ratio) of identical magnetic materials affects magnetostatic interactions during magnetization. Our findings demonstrate that precise tuning of the nanowire aspect ratio enables the magnetic properties to be modified as required, with this modification directly correlating with the magnitude and nature of internal magnetic interactions. These results provide valuable insights for optimizing the design of magnetic nanowire-based storage devices, paving the way for enhanced performance in future data storage applications.

磁性材料三维纳米线结构的发展是下一代信息存储技术的一个有前途的研究领域。先进的合成方法使磁性纳米线的高度有序阵列的制造成为可能，显著提高了数据记录密度。在这种设备中写入和读取数据的基本机制依赖于磁化反转过程。然而，单个纳米线之间的静磁相互作用对可靠的数据存储提出了挑战。研究了几何参数对纳米线磁性能的影响。具体来说，它检查了具有交替磁/非磁层的分段结构，以及仅由磁性材料组成的非分段结构。利用一阶反转曲线分析，我们系统地探讨了在磁化过程中改变相同磁性材料的纵横比（直径与长度比）如何影响静磁相互作用。我们的研究结果表明，精确调整纳米线的宽高比可以根据需要修改磁性，这种修改与内部磁相互作用的大小和性质直接相关。这些结果为优化磁性纳米线存储器件的设计提供了有价值的见解，为提高未来数据存储应用的性能铺平了道路。

This study presents an analysis of the Sutterby multi-diffusive nanoliquid flow over an expanding cylinder, incorporating an oscillatory magnetic field and activation energy, through the application of numerical simulation and artificial neural networks. Recently, artificial neural networks have attracted considerable interest owing to their applications in diverse fields, such as robotics, image processing, fluid mechanics, and beyond. This research aims to explore the transfer of heat and mass by employing numerical methods and artificial neural networks. The system consists of complex fluid-flow partial differential equations that are converted into ordinary differential equations by utilizing similarity variables. In the present problem, Buongiorno two-phase model is used, in the said model, slip due to nanoparticles at the wall is studied through two major slip mechanisms, namely, thermophoresis and Brownian diffusion. Further, by using MATLAB software, the reference data produced by the artificial neural network, which utilizes a Levenberg–Marquardt intelligent network, is allocated through three distinct characteristics: training, testing, and validation. The study involves calculating the mean squared error, analyzing histograms, and conducting regression analyses to demonstrate and assess the effects of the drag force and Nusselt number. The matrix laboratory function, utilized in addressing a boundary value problem through a 5th order method, enables the simulation of graphs and tables that clearly depict the various physical influences numerically represented in fluid flow profiles and gradients. The periodic magnetic field's intensity diminishes the energy transfer rate, concurrently leading to an elevation in the liquid's temperature, with the periodic characteristics of the magnetic field being distinctly evident. Furthermore, in the neural network simulation, 211 and 619 data points obtained from the numerical solutions of the velocity and temperature equations function as the databases throughout the training phase. In the training phase, the dataset is systematically partitioned into three subsets: 70 % is allocated for training purposes, 15 % is assigned for validation, and the final 15 % is set aside for testing, significantly.

This study investigates the random lasing characteristics of core-shell nano scatterers composed of Au@Cu and Cu@Au at different shell thicknesses (600, 1200, and 1800 pulses) in conjunction with Rhodamine 6 G (Rh6G) dye. The core-shell nanostructures were synthesized via laser ablation by precise control over the shell thickness and composition. The optical properties of these structures were analyzed under varying temperature conditions (30 °C, 35 À, 40 °C, and 45 °C) under a fixed pumping energy of 4.62 mJ to assess their impact on the random laser threshold, full-width at half-maximum (FWHM), and peak intensity. The experimental results demonstrate a strong correlation between the shell thickness and temperature-dependent lasing performance. Cu@Au nanoparticles with (1200 p) exhibit enhanced scattering efficiency and plasmonic coupling at room temperatures. The impact of temperature on random laser parameters is more pronounced in Au@Cu nanoparticles, with increasing copper shell thickness leading to enhanced lasing intensity and reduced FWHM. Specifically, at (1800 p), a transition from non-coherent to coherent random lasing was observed at elevated temperatures, indicating increased multiple scattering events. In contrast, Cu@Au nanoparticles exhibited improved thermal stability compared to Au@Cu nanoparticles, maintaining consistent lasing behavior across different temperatures, particularly at (1200 and 1800 p). These results highlight the potential of core-shell nanostructures for temperature-tunable random lasers, paving the way for applications in optoelectronics and temperature-responsive photonic devices.

本文研究了不同壳层厚度（600、1200和1800脉冲）下由Au@Cu和Cu@Au组成的核壳纳米散射体与罗丹明6 G （Rh6G）染料的随机激光特性。通过激光烧蚀技术，精确控制壳层厚度和组成，合成了核壳纳米结构。在固定泵浦能量为4.62 mJ的条件下，分析了不同温度条件（30°C、35 À、40°C和45°C）下这些结构的光学性质，以评估它们对随机激光阈值、半最大值全宽度（FWHM）和峰值强度的影响。实验结果表明，壳体厚度与温度相关的激光性能有很强的相关性。Cu@Au纳米粒子（1200p）在室温下表现出增强的散射效率和等离子体耦合。温度对随机激光参数的影响在Au@Cu纳米颗粒中更为明显，铜壳厚度的增加导致激光强度的增强和FWHM的降低。具体来说，在（1800 p）处，在高温下观察到从非相干到相干随机激光的转变，表明多重散射事件增加。相比之下，Cu@Au纳米颗粒比Au@Cu纳米颗粒表现出更好的热稳定性，在不同温度下保持一致的激光行为，特别是在（1200和1800 p）。这些结果突出了核壳纳米结构在温度可调随机激光器中的潜力，为光电子和温度响应光子器件的应用铺平了道路。

The primary cause of cancer-related mortality globally is still lung cancer, and existing treatment modalities, including radiation, chemotherapy, and targeted medications, are restricted in their effectiveness, toxicity, and high recurrence rates. Nanophytomedicine is a novel approach that combines nanotechnology and phytotherapy to enhance the pharmacological properties of bioactive compounds derived from plants. To differentiate this review from previous generalised cancer studies, it focuses exclusively on nano-engineered phytomedicines intended for the treatment of lung cancer. By enhancing the solubility, stability, bioavailability, and targeted delivery of phytoconstituents, nanocarriers enable traditional medicines to overcome significant constraints. The study identifies the molecular targets of specific phytochemicals within key lung cancer pathways, including immunological modulation, cell cycle arrest, apoptosis regulation, and angiogenesis inhibition, and systematically maps these phytochemicals to their corresponding nanocarrier systems. It highlights the fundamental principles that support precision medicine techniques in this way. In this rapidly evolving field, the review also critically assesses recent developments, translational challenges, and clinical perspectives. It also identifies knowledge gaps and potential future paths, including maximising carrier design, guaranteeing scalable production, and easing regulatory approval. With its multidisciplinary perspective at the intersection of nanomaterial engineering, phytochemistry, and lung cancer biology, this work offers a forward-looking framework for the development of safe, efficient, and tailored lung cancer treatments.

This work focuses on the synthesis, characterization, and applications of bare MgO nanoparticles (NPs) and CaO-MgO nanocomposite (NCs) thick films. The materials were prepared using the sol-gel method, with the thick films subsequently applied to glass substrates via screen printing. Comprehensive structural and optical analyses were conducted using FE-SEM, EDX, HRTEM, XRD, FTIR, and UV-DRS. The study explores the dual functionality of these films, evaluating their performance in both gas sensing and photocatalytic dye degradation. In gas sensing, the films were tested under a static system against various oxidizing and reducing gases, including H₂S, NO₂, CO₂, NH₃, CH₄, and LPG. The CaO-MgO NCs films demonstrated superior CO₂ sensing performance, achieving a high sensitivity of 94.29 % at a significantly low operating temperature of 80 °C and a low concentration of 500 ppm. This represents a significant improvement over bare MgO films, which exhibited a maximum sensitivity of 73.96 % at 160 °C with 1000 ppm CO₂, underscoring the enhanced sensing capabilities of the NCs. Furthermore, the photocatalytic efficiency of MgO NPs and CaO-MgO NCs was investigated for the degradation of Crystal Violet (CV) dye under simulated sunlight conditions. The NPs and NCs achieved impressive dye degradation efficiencies of 96.54 % and 99.72 % in 70 and 50 min, respectively, with the reaction kinetics following a pseudo-first-order model. Both catalysts also demonstrated excellent reusability and stability, retaining over 90 % of their efficiency after five consecutive cycles. This study concludes that the synthesized MgO NPs and CaO-MgO NCs thick films are a promising, multifunctional material with high efficiency for both low-temperature CO₂ gas sensing and photocatalytic environmental remediation, making them highly suitable for various practical applications.
