Synthesis of ZnO and MgO nanoparticles was done using sonochemical method.  Colloidal and powder nanoparticles were obtained using zinc sulfate hydrate and magnesium chloride as zinc and magnesium sources respectively.  Tetramethyl ammonium was employed as a surfactant.  Polyvinyl Alcohol (PVA) and Polyethileneglycol (PEG) were used as stabilizers. Characterization, following synthesis, was done using optical spectroscopy (Ultraviolet Spectroscopy), Infrared Spectroscopy (FT-IR), X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). Kinetics studies were done to further information on nucleation and growth.  These studies include changes in: reactants concentrations, sonication time and titration rate and heating time.  Optical studies show the formation of the clusters and the nanostructures. The absorption bands for the nanostructures formation were centered in 358 nm for ZnO nanoparticles and 335 nm for MgO nanoparticles.
