This study included two projects. In the first project, a controlled drug delivery was designed for Insulin. For this purpose, initially insulin was encapsulated in the porous of MCM-41, then prepared composite was coated using titanium dioxide and in this way a nanohybride composite was prepared and was characterized with FT-IR, XRD, TGA, FE-SEM and BET analysis. The releasing of insulin from this nanohybride composite was investigated in different pH. In the second project, first Ag/ZnO nanocatalystes were synthesized with different amount of Ag in ZnO, then nanocatalystes were characteized with FT-IR, XRD, UV-Vis, FESEM-EDX, TEM, XPS and ICP analysis. The nanocatalyst were used for oxidation of aromatic and aliphatic alcohols in the best condition of temperature, time, pressure,.... GC chromatography was used to find conversion and selectivity of products.
