Fluid-structure interaction plays an important role in the performance of various Microsystems. In many micro-devices such as micropumps, microvalves and micromixers, the fluid flow is driven by a vibrating solid membrane. Since the fluid also plays a role in resistance to the solid vibration and deformation, the solid vibration and the fluid flow are always coupled and a full fluid-structure interaction (FSI) analysis is required in order to investigate the performance characteristics of these devices. Since the frequency of the solid vibration is normally high in micro-devices, the time step size required for the finite element analysis of the fluid-structure interaction in these devices... 

Gas pollutants are included volatile inorganic compositions and odorous materials, which are harmful and dangerous for environment and human health. There are several methods for removing gas pollutants such as physical, chemical and biological methods. In this work, we discuss about ethyl-mercaptan adsorption in LPG by ZSM-5 zeolite and in use of micro systems (micro channels). This work is also concerned about micro channel coating by ZSM-5 and NaY zeolites on glass and the method of coating with (3-Chloropropyl) trimethoxysilane linker. After selecting the appropriate method for zeolite coating, we proceed to micro channel coating. In this research, four different designs of micro channel... 

During the past years, microtechnologies have been extensively used in Chemical reactions. In these systems, using an optimal system for separation, and purification of Chemical Products is of great importance. In this study, we have focused on the separation of organic-phase and aqueous-phase Products in 26 fabricated microsystems. The fabrication method of the glass microseparators consists of Lithography, Acidization, and Glass-to-Glass Thermal Connection. We have also studied key parameters of organic and aqueous phase separation in continuous capillary microseparators like the width of the capillary channel, length of the capillary channel, number of the capillary channels, and flow of...
