"The Adsorption and Self-Organisation of Silane Surface Modifiers on Metal Oxide Surfaces"

In the spirit of this joint meeting between South Australia's two leading scientific societies, I will describe a fascinating phenomenon that has been observed while performing multi-disciplinary research at the interface between physics and chemistry. Namely, during silane-based surface modification of metal oxide surfaces so called oscillatory adsorption occurs, whereby the coverage of the silane surface coating oscillates as a function of metal oxide substrate exposure. Both chemical and physical perspectives of the system will be described but particular focus will be placed on the developments that have been made towared unravelling this enigma, through attempts to model and identify the molecular mechanisms involved.
