    Abstract: We synthesize pure and (Ni, Al) co-doped Zinc Oxide (ZnO) nanoparticles by chemical co-precipitation method at room temperature successfully using poly ethylene glycol (PEG) as stabilizing agent. In the preparation, we kept one dopant element aluminum at constant concentration, 5 mol% by varying the other dopant concentration from one to three mol%... Show More

    Abstract: Lithium ion batteries are the most commonly used batteries at present, and because of the large number of people using and manufacturing them, the serious environmental problems caused by the final disposal of waste lithium batteries are worth discussing. In this study, lithium ion batteries were crushed with a crusher, and the obtained powder was ... Show More

    Abstract: AISI 4340 is known as super strength steel and widely applied in military equipment, aircraft components, automotive components, drilling device and so on because of its excellent behavior in wear, corrosion, fatigue, high temperature, and high-speed operating conditions. However, due to continuing work which reduced the performance of that compone... Show More

    Abstract: Plasma nitriding (also known as ion nitriding, plasma ion nitriding, or glow-discharge nitriding) is a method of surface hardening using glow-discharge technology to introduce nascent (elemental) nitrogen to the surface of a metal part subsequent diffusion into the material. Because of the formation of high compressive residual stresses in the case... Show More

    Abstract: The presence of quartz particle size (> 45 µm) has a deleterious effect on physio-mechanical properties of porcelain tiles. The effect is due to various factors including microstructure (pore) after sintering. This study aims at investigating the effect of quartz particle size (QPS) on sintering behavior and flexural strength of porcelain tiles mad... Show More
