“…A good amount of interfacial bonding is found between the Cu and ceramic reinforcements which thus accounts for an increased hardness of sample with a modest concentration of Gr.-TiC. [24][25][26] Figure 14 displays the compressive strengths of different specimens (Pure Copper and Composites) as a function of the concentration of Gr.-TiC. Specimen having 5 wt.% of Gr.-TiC shows the highest value of compressive strength, and it gradually reduces with an increase in Gr.-TiC reinforcement, as shown by the experimental data.…”

In the present paper, powder metallurgy (P/M) was employed to create copper matrix composites reinforced with Graphite (Gr.)-Titanium Carbide (TiC) [at 5, 10, and 15 wt. %]. Both Gr. and TiC was used in equal concentration as reinforcements. For this experiment, cylindrical specimens with approximate dimension of 30 mm in length and 10 mm in dia. were created by compacting milled powders under pressure of 540 MPa for 2 minutes. Green shaped cylindrical specimens were held at 900, 950, and 1000 degrees Celsius for 2 hours at the maximum temperature. Composite samples were tested for hardness and compressive strength. Specimens' microscopic structures were studied with the help of a variety of analytical tools, including an optical microscope, SEM, and EDS. In composites having copper matrix, reinforcement phase was found to be uniformly dispersed throughout the material. Compression strength in composites was increased by about 108% at 5 wt.% of Gr.-TiC reinforcement and by about 34% at 10 wt.% of reinforcements (Gr.-TiC). When Gr.-TiC reinforcement was added to a copper matrix at a weight percentage of 15 wt.%, the compression strength significantly decreased. The wear property of the produced composites was enhanced by including Gr.-TiC reinforcement into the copper matrix.

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.
