Global interest in metallic nano-crystals has recently increased dramatically as the realized applications of these structures begin to span the fields of nanotechnology and nano-biotechnology. In all these applications, control of the size and morphology of the nano-particles is critically important, as these characteristics determine their electronic, optical and catalytic properties. This requires an understanding of the underlying thermodynamic and kinetic driving forces, which govern nano-particle nucleation, growth and stability. This project will investigate the role of surface thermodynamics and growth kinetics in the nucleation, growth and stability of metallic nano-crystals in order to understand how to control their synthesis.Read moreRead less
