Ferromagnetism in II-VI Diluted Magnetic Semiconductor, Zn0.96Mn0.04O Nanostructures by Green’s Theorem
Abstract: Ferromagnetism in II-VI diluted magnetic semiconductor, Zn0.96Mn0.04O is studied. Using the Heisenberg principle, the spin exchange between the neighboring spin is discussed. Heisenberg’s model describes the Hamiltonian of the system in terms of spin density and excitons. Mathematically, magnetic parameters such as magnetizations and magnetic susceptibility are determined by Green’s function. Ferromagnetism is expected from sp-d exchange interactions (RKKY), point defects such as oxygen vacancies, and Zn interstitial and quantum …

Empirical Modelling of Metal Corrosion in Loamy Soil and Saltwater Environment
Abstract: The corrosion rate of metal in loamy soil and saltwater environment was monitored, predicted, and simulated using empirical modeling. The metal under investigation is carbon steel, which is found in a loamy soil and saltwater environments. The carbon steel sample immersed in a saltwater medium exhibited a higher corrosion rate compared to the loamy soil sample. The rise in corrosion of carbon steel can be attributed to the physiochemical characteristics …

Development of PVC Flute and Acoustic Testing for Commercial Production
Abstract: Flute is a musical instrument generally made of bamboo. Bamboo flute has less life and high price. Thus more durable material can be used which cannot be affected by environment. The PVC is most popular material which possesses these qualities and also cost effective. However, it should produce same pitch quality. This work focused on an idea to develop a high quality PVC pipe flute. A simple drill is used …

The Curvature Effect consideration in Euler beam theory
Abstract: The purpose of this paper is to improve the results of Euler beam theory. Euler beam theory can be used to determine the deflection of beam. But in some cases cross section of beam is not flat-ended, and Euler beam theory only consider the vertical loading, so the effect of curvature is occurred due to normal loading. The method to determine the curvature effect has been developed in this paper, …

Thermal Management Of Cylindrical Lithium-Ion Battery Using A Wavy Tube
Abstract: To maintain a proper temperature range and eliminate local temperature disparities, thermal management is required for lithium-ion batteries in electric vehicles. A wavy tube is presented for a liquid cooling cylindrical lithium-ion battery module in this research. On the suggested battery module, three-dimensional transient simulations were run, and numerical improvements were made by changing the wavy contact angle of the wavy tube. The heat dissipation efficiency and temperature field homogeneity …
