Interfacial Engineering and Performance Optimization of Jute-Fiber-Reinforced Epoxy Laminates
Abstract: The increasing environmental concerns associated with synthetic fiber reinforced polymer composites have driven substantial research interest toward naturally derived, biodegradable fiber alternatives. This study presents a comprehensive mechanical and thermal characterization of jute fiber reinforced epoxy composites fabricated via hand lay-up followed by compression molding. Jute fibers were subjected to alkali treatment using 5 wt% sodium hydroxide (NaOH) solution for 4 hours at ambient temperature to enhance fiber–matrix interfacial bonding …

Synthesis, Spectral Study, SEM Analysis and Antibacterial Study of New Indole Azo Ligand and Complexes
Abstract: Azo ligands have developed significantly in recent decades due to their fundamental role in the coordination chemistry of transition elements. Their rapid response to coordination bonding in ligand and complex chemistry, particularly with divalent ions, is a key factor. The azo-bridged bond has played a well-established role in the formation of cobalt, nickel, and copper complexes. In this study, we prepared a novel ligand, an indole derivative bonded to an …

Analytical Modeling and Simulation of Helical Gear Systems for Improved Load Distribution
Abstract: An analytical modeling and simulation methodology to improving load distribution in helical gear systems is presented in this research study. Fundamental parts of many mechanical systems, helical gears provide the benefits of smooth engagement, lower noise levels, and increased weight bearing capability. However, retaining lifespan and dependability in gear systems requires establishing regular load distribution throughout the gear teeth. This work explores the parameters influencing load distribution and suggests strategies …

Experimental Investigation of MRR and Surface Finish Using Abrasive Jet Machining of Aluminum Alloy 7475
Abstract: In this thesis, different experiments are performed on aluminum alloy 7475 by varying various parameters such as pressure, sand feed, transverse speed and standoff distance, i.e. nozzle-to-work-piece distance to determine material removal rates and surface finish. Optimization is done using L9 orthogonal array by Taguchi technique to determine better parameters to obtain maximum removal rates and minimum surface roughness. The parameters considered are transverse speed 50, 100, 150 mm/min; standoff …

Facile Fabrication of Durable Superhydrophobic Coatings on SS 304 for biomedical applications
Abstract: A simple and effective method to fabricate durable superhydrophobic coatings by combining shot-blasting and depositing sol-gel nanocomposite coatings on stainless steel SS 304 substrates has been investigated. Shot-blasting was used for two purposes; 1) as a method of physical modification for creating microscale roughness on the substrate and 2) for improving the adhesion of the nanocomposite coatings deposited thereafter. Organic-inorganic hybrid hydrophobic silica sol was synthesized where silica nanoparticles were …
