The g-C3N4-incorporated MnO2/MoS2 nanocomposite was successfully fabricated via a two-step hydrothermal approach. Structural and morphological analyses confirmed the uniform dispersion of g-C3N4 within the MnO2/MoS2 matrix, forming a porous interconnected framework that facilitates ion transport. Electrochemical analysis indicates improved charge transfer behaviour, suggesting enhanced electron transport within the composite. Electrochemical investigation in 1 M KOH shows that the MnO2/MoS2@g-C3N4 electrode delivers a high specific capacitance of 1535 F g⁻1 at 1 A g⁻1, outperforming the pristine MnO2/MoS2 electrode. The assembled asymmetric supercapacitor (MnO2/MoS2@g-C3N4//AC) exhibits an energy density of 60.6 Wh kg⁻1 at a power density of 800 W kg⁻1, along with 94.3
The preparation of nanoparticles through sustainable chemical practices offers an eco-friendly and feasible route to advanced nanomaterials. In this study, gold nanoparticles (Au-NPs) were synthesized using Garcinia mangostana (GM) peel extract, which is rich in antioxidants and provides biomolecules acting as bio-reductants, capping, and stabilizing agents. The synthesized Au-NPs were characterized by X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV–Vis spectroscopy, scanning electron microscopy (SEM), and photoluminescence (PL) spectroscopy. XRD confirmed the face-centered cubic structure of Au-NPs, while UV–Vis spectra exhibited a characteristic absorption peak around 540 nm. TEM images revealed polydispersed nanoparticles with diverse shapes and sizes. FTIR analysis indicated the presence of phenols, flavonoids, benzophenones, and anthocyanins, suggesting their role in the reduction and stabilization of Au-NPs. The catalytic activity of Au-NPs was demonstrated by the effective degradation of Fuchsin Basic dye, achieving up to 89
Advancing supercapacitor (SC) technology demands smarter electroactive materials to achieve higher performance. Herein, we display the preparation of niobium pentoxide (Nb2O5) and its mesoporous carbon composite using a less toxic hexam- ethylenetetramine (HMTA) as structure directing agent. The prepared nanostructures were explored towards SC electrode applications in Potassium (K+) based electrolyte as an alternate for Lithium (Li) based electrolytes. The morphological investigations reveal the as prepared Nb2O5 exhibiting rod like morphology and the composite sample showing firm attachment of porous carbon. As a SC electrode material porous carbon embedded Nb2O5 nanorods showing specific capacitance of 518 Fg− 1 at a current rate of 1 Ag− 1 in 0.5 M K2SO4 electrolyte with good cyclic life (91
With the goal to protect the network's resources against various threats, network security is vital. Every system associated with the network possesses vulnerabilities. These permit unlicensed users to attempt to go on with a certain level of intended use to access and use the system resources. One of the most significant threats to security for real-life scenarios is the increased potential for Distributed Denial-of-Service (DDoS) attacks. DDoS concept is used in order to make attempts more intense and effective. This focuses on DDoS Attack prediction and visualization techniques using Matplotlib functions of Python and its libraries to create graphs of various parameters that helps us to analyze the given “CSV” file of which stores the packets captured in the real time network.
This research utilizes 30 nm alumina (Al2O3) particles and 5–15 µm short carbon nanotubes (CNT) for the production of magnesium (ZK60) alloy hybrid nanocomposites, targeting applications in lightweight structural components. Magnesium-based composites are trending for their ability to fill specific properties in automotive, structural, and aviation applications. Liquid stir casting is a prominent process for making design-free components. However, this process is limited by uneven reinforcement distribution, voids, and porosity. Furthermore, a higher ceramic particle content leads to cluster formation, which, in turn, influences the functional properties of the composites. The current research investigates the microstructural, physical, and mechanical properties of ZK60 alloy hybrid nanocomposites developed via ultrasonic treatment, featuring a semisolid stir-cast process. An effective casting process and the significance of the CNT-Al2O3 hybrid filler in ZK60 provide homogeneous reinforcement distribution, reduced porosity, and an improvement in mechanical properties, as confirmed by microstructural and functional behaviour studies.
