The vibrations of carbon nanotubes under the influences of various internal and external forces have been subjects of interests for some years. These researches have not really considered the effects of surface energy and initial stress which are very important from both material and mechanical aspects of views. Therefore, the current study presents the simultaneous impacts of surface energy, initial stress and nonlocality and other various parameters on the nonlinear vibration of carbon nanotube hot fluid-conveying resting on elastic foundations in a magnetic environment. The derived equations governing the behaviours are solved using Galerkin’s decomposition-Adomian decomposition method is adopted to explore the concurrent impacts of surface elasticity, initial stress, residual surface tension and nonlocality on the nonlinear vibration of singlewalled carbon conveying nanotube resting on linear and nonlinear elastic foundation and operating in a thermo-magnetic environment

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.
