Plasma treatment is a relatively new technique and its applications are still being explored. Already, benefits in medicine and agriculture have been observed, such as increased healing rate of wounds, deactivation of cancer cells and enhanced/reduced germination rates.
While the complete process of plasma treatment is a global challenge, involving physics, biochemistry, medicine and engineering, the foundations of the microscopic processes are not well understood. This project aims to consider the behaviour of low-energy electrons in these plasmas and how they behave when impinging on liquid interfaces.
This project will model the scattering from and into a gas/liquid interface using simulations which include the collective effects that occur in liquids. These calculations will pave the way for analysis of an experiment that has recently been granted ARC funding at Flinders University.
As part of this project you will:
- Develop a simulation of electrons in gases and liquids using Monte-Carlo track code.
- Explore interfacial shape profiles and see how they affect the reflection or transmission rates.
- Create a useful simplified model from the complex microscopic dynamics.
The aims and goals of this project can be adjusted to suit the time available to the student.
