Multifunctional and Photocatalytic Properties of DyFeO₃/Dy₃Fe₅O₁₂ Biphasic Nanoparticles
Abstract: Rare-earth orthoferrites constitute a class of compounds that exhibit remarkable magnetic, optical, and electronic properties across a wide temperature range. In the present study, a dysprosium-based orthoferrite containing dual phases of DyFeO₃ perovskite and Dy₃Fe₅O₁₂ garnet was successfully synthesized via the co-precipitation technique. X-ray diffraction (XRD) analysis was employed to investigate the structural configuration of the synthesized material. The diffraction pattern confirmed the formation of a biphasic composite comprising orthorhombic …

Comparative Analysis of Polymer-Enhanced and Conventional Magnetorheological Fluids in E-Bicycle Semi-Active Suspension
Abstract: In light of the increased use of electric bicycles as a sustainable transport means, various mechanical challenges emerge which were absent in traditional bicycles, primarily concerning vibration isolation and riding comfort. Indeed, hub motors, batteries and the entire drivetrain system produce dynamic excitations which passive suspension cannot handle effectively. This paper presents a comparison of conventional magnetorheological (MR) fluid and the polymer-based MR nanocomposite fluid within the context of semi-active …

Green Synthesis and Evaluation of Electronic and Optical Properties of CdS/CdTe Quantum Dots
Abstract: The CdS/CdTe quantum dots (QDs), with altered concentrations of CdS, were synthesized using straightforward precursors through an environmentally friendly green method. The synthesized quantum dots were characterization by UV–visible absorption spectroscopy, Photoluminescence (PL), and Fourier Transform Infrared Spectroscopy (FTIR) to understand their electronic and structural properties. The average particle size is nearly consistent with the values derived from Brus's formula. The UV–visible spectra show a blueshift compared with pure sample, …

Investigations into the Mechanical and Thermal Properties of Fe3C Compound: A Comprehensive Analysis
Abstract: Exploration of mechanical properties of Fe3C powder using Williamson-Hall analysis by using Mechanical alloying technique. The primary objective of this study is to investigate the lattice strain (LS) and nanocrystalline size (CS) in an Fe3C produced from powder using the Mechanical Alloying Method (MAM). By the repeated mechanical crushing, the LS created by MAM is expected to decrease while the CS is anticipated to reduce the particle size. To accomplish …

Comparative Study of Parabolic Leaf Spring and Different Materials
Abstract: AbstractSprings are used in automobile applications as they expand in size when loaded and regain its original shape when removed. They also absorb vibrations, shocks and loads utilizing damping, they absorb the energy in the form of potential energy. Springs’ capacity to absorb and store more strain energy makes the suspension system more comfortable. Conventional spring and parabolic springs are widely utilized springs and are currently the topic of research …

Feature Extraction and Analysis of Bearing Faults: A Review
Abstract: One of the most important steps in identifying bearing problems is feature extraction. In order to provide a more meaningful dataset, it entails locating and extracting pertinent features from raw bearing vibration signals. Tasks involving categorization and prediction can then make use of these attributes. In many practical applications, such as monitoring rotating machinery or electronic components, the raw signals collected (e.g., vibration, current, temperature) are often complex, high-dimensional, and …
