Applied Physics Division Committee
Plasma propulsion: Feasibility of a new type of electric propulsion system.
Activities include experimental investigations and construction of mathematical and computational models to determine efficiencies, physical principles and space mission parameters. The aim is the inclusion of such a propulsion system on a functional CubeSat.
Renewable energy: We work on improvements on a receiver for a solar trough systems. Improvements include hyper-concentration of solar beams, cavity type receiver geometries and inclusion of a hot mirror to increase solar to heat efficiencies. Performance is modelled theoretically, experimentally and computationally.

MSc topic: Optimization of processing parameters in the preparation of hematite thin films for PEC device
Supervisor: Prof Mmantsae Diale
Research project is on the influence that various processing parameters have on hematite thin films, for applications in photoelectrochemical water splitting.
Interests in Applied Physics include research using computational methods applied to HIV-AIDS epidemiology, as well as research in bibliometrics, solar energy, and solar radiometry.
