Professor George Kaptay (BAY-NANO Research Institute, University of Miskolc, Hungary) describes the different work he has been conducting over the past few years. From the field of interfacial phenomena he will be talking on the formation of a nano-layer on the surface of immiscible alloys and on its influence on the Marangoni convection and on technologies like welding. He also will show the reasons why nano-nuclei can be stabilized during nucleation from diluted liquid solutions or vapour. From the field of chemical thermodynamics he presents a new formalism to describe temperature dependence of excess Gibbs energy to avoid calculated artefacts during phase diagram calculations. From the field of transport properties he presents his recent unified equation for the viscosity and self-diffusion coefficient in liquid metals, and also the equation, connecting the composition dependence of viscosity and heat of mixing in liquid alloys. Finally, the way in which metallic foams and emulsions can be stabilized by solid particles is described.



Professor Kaptay was invited to Swinburne under the Board of Research Visiting Professor Grant Scheme, and this lecture was presented as part of the PVC(R) Visiting Professor Lecture Series.
