Effect of Tween 20 on the Electrochemical Synthesis and Properties of Nickel Hydroxide Nanoparticles Nickel (II) hydroxide (Ni(OH)₂) nanoparticles have attracted significant research interest due to their potential in applications such as supercapacitors, batteries, and electrocatalysis. However, conventional synthesis methods often face challenges related to high costs and complex instrumentation. This study presents a simple, low-cost, and controllable approach for synthesizing Ni(OH)₂ nanoparticles using a surfactant-assisted electrochemical method. The synthesis was conducted through electrolysis at 100°C in an aqueous solution containing sodium citrate, with Tween 20 employed as a structure-directing agent, Tween 20 was effective in producing smaller, dispersed, quasi-spherical particles while preventing severe agglomeration. The resulting nanoparticles were characterized using various analytical techniques, including UV-Vis and FTIR spectroscopy, X-ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA), and electron microscopy (TEM/SEM). UV-Vis analysis showed a characteristic absorption peak at 387 nm, confirming nanoparticle formation. XRD analysis validated the synthesis of a nanocrystalline hexagonal Ni(OH)₂ phase. Electron microscopy revealed a hierarchical, flower-like morphology composed of nanosheets and demonstrated that Tween 20 was effective in producing smaller, dispersed, quasi-spherical particles while preventing severe agglomeration. Furthermore, the thermal decomposition of Ni(OH)₂ into highly crystalline cubic, NiO via calcination was confirmed by TGA, XRD, and FTIR analyses, with the main decomposition occurring at approximately 335°C. This research demonstrates an effective and economical route for producing Ni(OH)₂ nanoparticles with controlled morphology, enhancing their potential for practical applications.

Python Based Property Evaluation of Co-Zn Ferrite: Using results of XRD and FTIR The study focuses on making a new material by mixing different combinations of cobalt, zinc, and iron with sodium hydroxide. These formed materials are known as ferrite. The main goal of this study is to investigate how the properties of synthesized ferrite change as we change the composition. These types of ferrites have practical uses in industries like electronics, magnets, nuclear energy sector, and healthcare. By understanding how various variations in material's composition affect the properties of material researchers can design materials which have higher efficiency and greater longevity. Based on the result of the above study this research presents a further investigation into the analysis of Co-Zn substituted ferrite nanoparticles by applying advanced data analytics using Python. Python allows for statistical evaluation, processing and modeling, as well as visualization of XRD for structural analysis of material and FTIR data for functional group analysis of material. Different aspects of XRD analysis cover the intensity vs. 2Theta spectrum visualization which gives various information about composition of material, identification of peaks, Scherrer methodbased crystallite size estimation, and determination of lattice parameters. FTIR techniques involve spectral peaks identification, functional groups assignment, and an estimation of the material’s band gap. The integration of these technologies provides an improved understanding of spinel phase formation, nanoparticle size distribution, and other structural changes in material. By integrating FTIR analysis, peak detection, functional group identification, and FWHM-based crystallite size estimation, we can obtain better interpretation of experimental data, which leads to enhanced insights into material properties. This procedure contributes significantly to advancing research in nanoscience and the thorough characterization of synthesized materials.

Polymeric bio-based nanodispersed admixtures for the production of hydrophobic Portland cement mortars A current trend in the construction industry involves the development and employment of eco-friendly, durable, and sustainable materials. Numerous admixtures, including various polymers, are used to modify the properties of cement. Nonetheless, their effectiveness and environmental impacts are still a matter of discussion. In this context, this work was focused on the application of innovative vegetable oil-based polymeric nanodispersed admixtures, synthesized following green chemistry principles, such as using water as a solvent. The synthesized bio-based latex admixtures were incorporated with 30 wt% of vegetable oil-based monomers derived from camelina, linseed, and rapeseed oils. The produced ordinary Portland cement fine-grained mortars, containing 0.1 wt% of each bio-based latex admixture, were thoroughly examined using several instrumental methods, such as isothermal calorimetry and scanning electron microscopy, to gain a comprehensive understanding of the roles of bio-based latex admixtures on the physical, mechanical, and microstructural properties of the examined specimens. It was found that the addition of bio-based latex admixtures led to changes in the hydration process, mineralogical composition, and liquid water transport. For example, the water absorption coefficient was found to be approximately 40% lower compared to cement mortars produced using a reference latex additive without the vegetable oil-based component. Moreover, cement mortars with a bio-based latex admixture containing camelina oil exhibited comparable compressive strength to those produced solely from ordinary Portland cement. Thus, the newly developed bio-based polymeric nanodispersion represents a new class of environmentally friendly admixtures that may be effectively utilized for water-loaded structures.

Two new doping-free manufacturing processes for bread-derived carbon electrodes with control over micro- and macro-topological surface features Pyrolyzed carbon electrodes (PCEs) can provide sustainable alternatives in electric devices, but it is difficult to control their surface geometries during their semi-destructive fabrication procedure. Impressive contributions have been made to the field of PCE fabrication in terms of the nanoscale, functionalization, and separation applications; however, further progress towards an emphasis on a sustainable life cycle is the next step forward. Here, we propose two new methodologies for creating sustainable PCEs: stamping, where a user-designed, 3D printed electrode precursor (EP) imparts a shape on an organic material, and reconstitution, where the same EP acts as a mould as a mixture of agitated organic material and water dries to leave behind a rigid shape. Both methods allow for the reuse of the EP and the upcycling of biologically derived waste products as a pyrolytic input, and they do not require chemical modification. A comparison of the two methodologies is discussed as surface features of PCEs scale by a factor of 0.78 during the reconstitution process and by a factor of 0.68 during the stamping process. These PCEs maintain defined structures on the micro-scale and demonstrate previously unachievable resolution to the naked eye prior to these two novel pathways.

Effects of Green and Chemical Cerium Oxides Nanoparticles on the Blood Profile and Liver Enzymes of Cirrhinus mrigala As nanotechnology advances, minute contaminants are increasingly found in both the terrestrial and aquatic environments, raising concerns about nanoparticle pollution such as cerium oxide. They could be consumed by fish and other aquatic life, leading to poisoning, illness, and even death. The goal of the current study was to investigate how cerium oxide nanoparticles physically affected the freshwater Cirrhinus mrigala's liver and hematological markers. Fish for 28 days were exposed to two dosages of each type: 50 mg and 100 mg. The fingerlings in each experimental aquarium were twelve. Following CRD, hepatotoxicity was measured in a spectrophotometer Microlab 300® using the QCA diagnostic kit method for markers such as ALT and AST, alkaline phosphatase (ALP), and total bilirubin. Hematological parameters were evaluated by CBC tests, which included hemoglobin, hematocrit, differential RBCs, WBCs, and platelets. One-way ANOVA was used to statistically examine the data. This study showed that both chemically produced cerium oxide nanoparticles and green cerium oxide had an effect on the liver and blood profile of Cirrhinus mrigala. Histopathological analysis revealed cellular deterioration and necrosis in the liver tissue. Hematological markers like white blood cell counts and hemoglobin levels showed notable variability in the blood profile. These results suggested that both kinds of nanoparticles may have toxicological consequences on fish.

Here, a simple and fast way of surface modification of carbon cloth (CC) is proposed. The surface-modified carbon cloth (MCC) was obtained by a few minutes of simple treatment using a microwave oven. The MCC had a porous structure and was assembled with zinc sheets to form ZHSCs with an excellent surface capacity of 0.82 mAh cm-2 and outstanding rate performance. Moreover, a capacity retention of 90.15% was demonstrated by the ZHSCs following 15,000 cycles at a current density of 20 mA cm-2. This outcome offers a straightforward and cost-effective approach for the fabrication of flexible electrodes.

Novel Cu-Fe codoped NiO nanocrystalline semiconductors with superior room-temperature ferromagnetism and high dielectric performance for spintronic devices Nickel oxide (NiO) has the potential to be a p-type diluted magnetic semiconductor, but its limited room-temperature ferromagnetism (RTFM) and dielectric properties make it less useful. This study addresses these limitations by synthesizing pure NiO, Cu-doped NiO (Ni 0.95 Cu 0.05 O), and Cu-Fe codoped NiO (Ni 0.95 Cu 0.025 Fe 0.025 O) nanopowders using NaOH-assisted co-precipitation. Rietveld-refined X-ray diffraction (XRD) confirmed a cubic structure with lattice parameter changes, while scanning electron microscopy/transmission electron microscopy (SEM/TEM) revealed reduced crystallite sizes from 23 to 10 nm. X-ray photoelectron spectroscopy (XPS) confirmed Cu 2+ and Fe 3+ oxidation states and oxygen vacancies. The measurements showed that the codoped sample exhibited a colossal dielectric constant (ε′ &gt;10 5 at 50 Hz) and enhanced saturation magnetization (3.5 emu/g vs. 0.47 emu/g for pure NiO). These improvements arise from synergistic effects: Cu doping promotes oxygen vacancies for space-charge polarization, while Fe enables bound magnetic polarons (BMPs). Thus, Cu-Fe codoped NiO emerges as a prime candidate for spintronics and high-density energy storage applications.
