Abstract: Metallic foam is a type of cellular solid structure that consists of gas filled in its pores. The cell wall of pores can be opened or closed. Much development has been done in recent years to increase the applications of metallic foam in real life such as clinical, medical and engineering applications. There are various engineering applications such as aerospace, railway industries, heat exchangers, automobile industries and many more. However main emphasis is laid on automobiles. For which it is found that CaCO3 is the best suitable agent for the manufacture of Mg-foam. However, no research had been done on Dolomite for the fabrication of Mg-foam. In this paper, an attempt is made to use the Dolomite as the foaming agent.

Abstract: Kinetic of modeling data is necessary for the industrial use of adsorption. Under changed conditions, kinetic offers evidence for operational conditions for designing and optimizing effective situations for removing the pollutant. The pseudo second-order equation was used in this study in order to investigate the mechanism of adsorption of mercury by the CNTs and the potential rate-controlling steps, such as mass transport and chemical reactions. The interaction model shows how contact with different pH affects the residual concentration of the mercury at two different times. The first (contact time of 20 minutes) showcase of the removal of the mercury does not reduce much when the pH varies from pH 5 to pH 8. The second (contact time of 120 minutes) however shows that the pH affects the removal of mercury at pH 5, the residual concentration was lower compared to the residual concentration at pH 8.
