This study extensively focuses on analyzing the fretting wear characteristics of Aluminum-based hybrid Metal Matrix Composites (MMCs) under dry conditions, essential in understanding materials' tribological properties in mining environments. Aluminum-based MMCs offer improved wear resistance and durability, potentially enhancing mining equipment performance. The investigation targeted Aluminum 7075 alloy-based MMCs, comprising 7% fine greenish Silicon Carbide and 3% chopped E-glass fibers (2-3mm length, 10-14 micrometer diameters). Using traditional stir casting and Friction Stir Welding (FSW) techniques, composite plates meeting ASTM standards were fabricated. FSW parameters like rotation speed and tool feed rate were varied.Analyzing fretting wear on the welded zone, employing different loads through Linear Reciprocating Tribometer (LRT), provided insights into the tribological performance of these Aluminum-based hybrid MMCs. The lightweight and exceptional thermal properties of Aluminum have significantly expanded its use across various industries, enabling partial replacement of ferrous materials, especially in MMCs where Aluminum alloys offer distinct advantages over other materials.This research aids in determining the suitability of these MMCs for demanding mining conditions, where materials endure extreme stress. Understanding their tribological behavior is crucial for potential applications in mining equipment, contributing to longevity and improved performance.

The focus of recent studies has been on 3D printing technologies. Models are manufactured using magnetic resonance imaging, computed tomography, or echocardiography in three dimensions (3D printing) , and the process is also known as additive manufacturing. The debate about 3D printing's function in cardiology is the main focus of current studies . To decrease the mortality rate due to heart related diseases like cardiac arrest , which has been tremendous in recent times, 3D printed models serve as a savior of life. To illustrate, during COVID-19, the coronavirus created a global pandemic and a huge global demand for medical equipment. The shortage of time and the high level of social distancing make it difficult for the government and medical professionals to face the pandemic. In those critical times, 3D printing models were used to develop medical equipment and explore its potential by addressing the shortage of equipment. The physical models are printed using various methods like Fused Deposition Modeling, Polyjet, Stereolithography, Selective Laser Melting, and Sintering. This also enhances the practical knowledge of students and surgeons and revives confidence in the patients and their families.

“…They are the first choice of researchers and engineers because of their low density, good heat and electric conductivity, resistance to corrosion and high endurance [84][85]. Aluminium metal matrix composites play a very significant role in the modern world because of their versatile properties such as high strength to weight ratio, ductility, high recycle potential, corrosion resistance, [92][93] electrical and thermal conductivity along with that aluminium alloys have slighter tensile strength and wear property [89][90]…”

This study highlights the importance of Modern Street light control systems over traditional ones, with LED lamps emerging as the most suitable choice due to their advantagessuch as reduced heat production, lower electricity consumption, and extended lifespan. The main goal is to enhance system efficiency by minimizing unnecessary electricity loss during daylight and when lighting is not required. Automating street lights using LDR and PIR sensorsin conjunction with Arduino Uno offers a costeffective and secure solution, eliminating the drawbacks of manual switching and simplifying cost reduction and maintenance. Additionally,applying a ZnO coating to the street light casings provides effective protection against dust and moisture, resulting in efficient lighting. The process involves sol-gel deposition of ZnO nanoparticles on silica glass substrates, followed by preannealing and repeated dip coating. Annealing at temperatures between 450°C and 600°C further improves the results. The uniformand defect-free coatings are confirmed by SEM images, while transmission spectra reveal over80% penetration of visible light (400 nm to 900 nm). Lower precursor concentrations lead to better penetration of light below 300 nm wavelength.
