In this study, we are implemented the modified Sub-ODE scheme to recover a variety of optical solitons for the (3+1)-dimensional nonlinear Schrödinger equations that have two types of self-phase modulation effects, nonlocal law nonlinearity and Kudryashov’s quintuple power law. Bright, dark, and singular soliton solutions along the dark–singular form of straddled solitons are revealed. The results show the powerful impact of system parameters on the amplitude of soliton. Graphical illustrations are presented to analyze the physical characteristics of the obtained solitons and to highlight the role of the magneto-optics waveguide transmission. The findings allow to conclude that the developed technique is accurate and consistent.
This work examined the dielectric properties of Cu-Mn-La spinel ferrites (Cu0.5Mn0.5La0.03Fe1.97O4)/x-GNPs composites synthesized by the sol-gel auto-combustion route. To modify the dielectric properties of the prepared composite materials, graphene nanoplatelets (GNPs) were introduced at different concentrations, such as 0, 1.25, 2.50, 3.75, and 5 wt
In this work, nanoporous nickel oxide nanoparticles (NiO NPs) were synthesized by the hydrothermal method with systematic variation of the precursor solution pH. X-ray diffraction (XRD) study confirmed the formation of a pure, crystalline face-centered cubic (FCC) structure of NiO NPs without secondary phases. Morphological studies using FESEM revealed that pore formation and connectivity significantly improved with increasing pH, resulting in an optimized, uniform nanoporous NiO NPs structure at pH 14. Raman spectroscopy further validated the presence of defect-rich sites and phonon-magnon interactions. The UV-vis and photoluminescence (PL) analyses demonstrated the tuning of optical properties and a reduction in bandgap energy from 4.16 eV to 3.1 eV with increasing pH. Electrochemical performance evaluation revealed excellent redox activity and high specific capacitance, highlighting the potential of the synthesized nanoporous NiO NPs for energy storage applications. The results indicate that precise pH control plays a vital role in tailoring the structural, optical, and electrochemical characteristics of NiO-based nanoporous materials. This study systematically investigates how precursor-solution pH influences the hydrothermal synthesis of nanoporous NiO NPs and establishes a clear relationship between pH-controlled structural evolution, defect formation, optical bandgap tuning, and electrochemical performance. Unlike previous reports, the present work provides a comprehensive correlation between pH-induced nanoporous architecture and multifunctional properties.
In this research ZnO/Al2O3 nanocomposites have been successfully synthesized by hydrothermal method and their potential application as electrode materials for electrochemical supercapacitors have been investigated. The synthesized ZnO/Al2O3nanocomposite was thoroughly characterized for its structural, morphological and compositional properties using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX). This study effectively manufactured ZnO/Al2O3nanocomposites using the hydrothermal process and explored their potential use as electrode materials for electrochemical supercapacitors. Furthermore, the surface chemical states and bonding configurations of the nanocomposite were ascertained utilizing X-ray photoelectron spectroscopy (XPS) in conjunction with synchrotron radiation. The electrochemical characteristics of the ZnO/Al2O3electrodes and the constructed supercapacitor apparatus were meticulously examined using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), electrochemical impedance spectroscopy (EIS), and extended cycling stability assessments in a 3 MKOH electrolyte. The ZnO/Al2O3electrode exhibited a remarkable specific capacitance of 550 F g− 1 at a current density of 1 A g− 1 and maintained 89
This research explores the physical characteristics of Tin Oxide (SnO₂) thin films prepared using a precursor solution nominally containing Fluorine and Aluminum (F + Al) co-dopants. The films were synthesized via the cost-effective Chemical Spray Pyrolysis (CSP) method on flexible DuPont Kapton polyimide (PI) substrates. A systematic investigation was conducted to determine how varying the substrate temperature (Ts) between 350 °C and 400 °C influences the films’ structural, morphological, and electrical properties. X-ray diffraction (XRD) results identified a polycrystalline tetragonal cassiterite phase, noting that crystallinity peaks at 400 °C along the preferred (110) orientation. Surface analysis through field-emission scanning electron microscopy (FE-SEM) indicated a morphological evolution toward a continuous and highly coalesced structure at 400 °C, which minimizes grain boundary effects without causing detectable macro-thermal degradation of the PI substrate. High optical quality was observed, with visible light transparency exceeding 85
