Application of Molecular Simulation to Coatings Design, G. Yiapanis, D. J. Henry, E. J. Evans and I. Yarovsky, in "Nanotechnology in Australia: Showcasing Early Career Research", Eds. D. M. Kane, A. P. Micolich and J. R. Rabeau, ISBN: 9789814310024, Pan Stanford Publishing, 2010
Our research team is responsible for the theoretical modelling project aiming to optimise the molecular design of coatings for resistance to biological contamination (bio-fouling).
Bio-fouling is one of the top priorities amongst the market driven product innovations in coating technologies. We employ advanced computational modelling techniques to understand the molecular mechanisms of the interactions of biomolecules with engineered surfaces and assess the antifouling ability of various functional grafted chains.
These studies will help design surface treatments to prevent microbial and fungal adhesion which is an issue of paramount importance for manufacturers of industrial and biomedical coatings and materials. We use the latest techniques in computational modelling of atomic structure of biomolecules and surfaces to explore the molecular mechanisms of their interactions.
We work with our collaborating experimental research teams and BlueScope Steel, a world class steel manufacturing company.

Grants and funding
Funded by the ARC Research Hub for Australian Steel Manufacturing (IH130100017) 2014-2019. The ARC Research Hub for Australian Steel Manufacturing, headquartered at the University of Wollongong, was officially launched at Parliament House by Minister for Industry, the Hon. Ian Macfarlane MP on 4 September 2014.
The Hub is supported by industry and university investment of more than $17 million and ARC funding of $5 million over five years. The ARC Research Hub is engaged in developing breakthrough process and product innovations to solve complex challenges confronting the Australian steel industry.
