THERMODYNAMICS OF HEAVY METALS (Hg2+, Cd2+, Fe2+AND Ni2+) ADSORPTION USING BOILER FLY ASH
Abstract: The effect of temperature on the adsorption of heavy metals, Hg2+, Cd2+, Fe2+ and Ni2+ using unactivated boiler fly ash (an agricultural waste) was investigated. The results showed that Hg2+ and Cd2+ ions were mostly affected by increase in temperature because their sorption rate decreased at high temperature. At the temperature of 273 K and 383 K, the amount of Hg2+ adsorbed (mg/g) by the unactivated boiler fly ash was …

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.

Chemical Process of Diamonds and CVD Methods
Abstract: Many times, first-order kinetics can be seen in gas-phase decomposition events. However, it is now known that such reactions are actually governed by bimolecular processes. Bimolecular collisional activation to an energy sufficient for decomposition sets off the reaction. Gas-phase processes occurring in catalytic cycles are also to blame for the development of the ozone hole in the polar stratosphere in the spring, albeit heterogeneous mechanisms must also be taken into …

Review of Silicon Reactivity of Self-assembled monolayer and its Properties
Abstract: In most cases, the assumption of perfect high viscosity between silicon and silver underlies the modelization of silicene on Ag(111). According to recent reports, growth does not take place on top of the Ag(111) terraces, but rather within the first layer of them. In this article, we present the results of a study that combines scanning tunnelling microscopy and density functional theory to simulate the nucleation process and reveal the …

Mechanisms for Biological Energy Transduction
Abstract: One of the most intriguing aspects of plant metabolism is energy transduction, and a significant amount of study has gone into understanding the process by which the different activities operate. When light energy is employed in the chloroplast to create Adenosine triphosphate (ATP) from Adenosine diphosphate (ADP), transduction is taking place. This is the process of converting one form of energy into another. The reactions involved in this research are …

Study and Characterisitics of Different GVF Profile of Rectangular Channel
Abstract: This technical note presents the equation for one-dimensional gradually-varied steady flow profiles with constant discharge, in a rectangular-section prismatic channel of constant roughness and small longitudinal slope. The flow profile differential equation was transformed by means of a polynomial approximation and then, by an algebraic procedure followed by the integration of the equation, the solution was obtained. This solution was applied to a particular case which, through a comparative analysis, …

Retrofitting of Existing Building by Concrete Jacketing
Abstract: Seismic Retrofitting is engineered mitigation techniques for structural engineers. It is defined as the modification of existing structures to make them more resistant to seismic activity, ground motion or soil failures due to earthquakes. It is generally required for earthquake damaged and vulnerable buildings with no exposure to severe earthquakes. Retrofit enhances the structural capabilities of the building. In present time, there are many local and global retrofit techniques in …
