FY2013 Annual Report

Nanoparticles by Design Unit

Associate Professor Mukhles Sowwan


In FY2013, the focus was primarily on studying the new creation and the growth mechanisms of size selected nanoparticles using magnetron sputter inert gas condensation method. The nanoparticles were characterized using different nanotechnology tools such as the X-Ray Diffractometer (XRD), X-ray Photoelectron Spectrocospy (XPS) system, and the Environmental Transmission Electron Microscope (ETEM), in addition to molecular dynamics simulations and modeling.
