Corrosion Protection of Copper Metal by Nanocoating in Nitrogen dioxide Environment
Abstract: Nitrogen dioxide is an acidic gas. It absorbs moisture to produce nitric acid. It creates corrosive medium for copper metal. It forms corrosion cell on the surface of copper and accelerate corrosion reactions. The corrosion cell formation is written as: Cu|Cu2+||H+|H2 thus corrosion reactions start and copper is oxidized into Cu2+surface and it is oxidized into Cu2+ whereas H+ ion is reduced into H2. Nitric acid environment copper exhibits galvanic, …

Analysis of various thicknesses of Shear Wall with Opening and without Opening and their Percentage Reinforcement
Abstract: Due to increase in population spacing in India is needed, especially in urban areas. Structural engineers in the seismic regions across the world often face the pressure to design high rise buildings with stiffness irregularities, even though they know these buildings are vulnerable under seismic loading. Today’s tall buildings are becoming more and more slender, leading to the possibility of more sway in comparison with earlier high rise buildings. Improving …
