In this research paper, the Finite Element Analysis is used for the investigation. The modal of polycarbonate bullet proof glass and the abrasive particle is prepared to study the effect of machining mechanism. Through analysis, it concludes that hard abrasive gives the large stressed zone, which increases the material removal rate. In this experimental study, Boron carbide abrasive gives better material removal rate as compared to Silicon carbide and Alumina Abrasive. It also observed from the analysis, higher material removal rate also encourage the tool wear rate. Boron carbide gives higher tool wear rate as compare to other abrasive. The results are verified with the experimentation, it gives the approximately same results of Finite Element Analysis.

Electro-anodization of thin Ti film deposited on glass substrate by RF sputtering technique was employed to fabricate TiO2 Nanotubes (TNTs) annealed from 350°C to 650°C. The morphological analysis were done using Scanning Electron Microscopy (SEM), which showed the change in the surface morphology with increase in annealing temperature. The structural analysis was performed using X-ray Diffraction (XRD) and Raman spectroscopy. XRD revealed the presence of anatase phase TiO2 with most intense anatase peak found at 550°C, at 2θ of 28, 9° (101). Raman revealed the presence of only anatase phase of TiO2, and showed well-improved crystallinity of the TNTs upon increasing in annealing temperature.

Pure and Cu+2/Fe+3 codoped ZnO nanoparticles were synthesized by polyol method. X-rays diffraction, scanning electron microscopy, dispersion X-rays spectroscopy; UV-Vis spectroscopy and photoluminescence were used for the characterization of the as synthesized nanoparticles. X-ray diffraction study of as synthesized nanoparticles presented the hexagonal wurtzite phase of ZnO structure. Optical studies revealed a blue shift in the absorption spectrum when ZnO was doped with Cu+2/Fe+3. The degradation rate of disperse blue dye using ZnO and codoped ZnO nanoparticles were considered under the solar region. ZnO and codoped ZnO degrade dye under consideration however, codoped ZnO nanoparticles proved to be extra efficient catalyst as compared to ZnO nanoparticles. The kinetic study of the dye was also calculated and it was observed that degradation of the respective dye followed pseudo first-order kinetics. The as-synthesized nanoparticles prove to be environment-friendly and active and can be vastly used for the purification of water polluted by different dyes that are carcinogenic in nature.

Very recently, new exact analytical solutions of the Fourier heat equation have been proposed by Zhukovsky. Since the Zhukovsky solutions are very powerful we applied the Zhukovsky formalism to a specific experimental situation, i.e. to a one dimensional (1D) lattice composed of Au nanoparticles of radius 20 nm in water media, under 20 ns laser pulse irradiation. In addition, we calculated the thermal field in the 2D spatial dimensions case for a single Au nanoparticle in water irradiated under the same conditions but with a different fluence. These results exemplify how the new Zhukovsky formalism contributes to the real physical view of such laser thermalized processes. This new theoretical approach could be easily extended to laser processing in general, and laser additive manufacturing in special.

The new thermal treatment of subcritical annealing and water quenching, applied to boron steels (30MnB5), which we propose in our research, achieve excellent variability in mechanical properties, as a result of obtaining a very versatile dual structure. In addition, there is a significant reduction in energy consumption and process time, which results in the Life Cycle Analysis (LCA) and process costs. The presence of boron favours the success of the thermal treatment. The explanation of the process has been investigated by means of a metallographic study, mechanical characterization and in this work the results obtained by means of the study of the treated and untreated samples by means of X-Ray diffraction are presented. The presence of very small FeB crystals in the structure are the cause of the dual structure and its good characteristics. They have only been detected by X-Ray Diffraction, although we have also tried Transmission Electron Microscopy with unclear results.

In recent years Al2024 alloy had increasing applications in all the areas due to its good formability, excellent properties and etc. By using nano size B4C as size and graphite as reinforcements the fabrication process are done by Powder metallurgy process with overall 12 compositions primary and secondary specimens. Nano B4C are used as reinforcements from 3-15% with step of 3% as primary specimen and with addition of graphite of 3% in every reinforcements same manufactured. All specimens are manufactured by powder metallurgy technique and had a wide application. Hardness values are taken and each specimen is subjected to aging process. In aging process are subjected to 495°C and soaking for 2 to 10 hours. The cooling process can done by in three medium water. In each case hardness values are taken with micro Vickers tests. All results are taken shows that increase in hardness with aging process. FESEM analysis is conducted to know the microstructure of composites.
