Environmentally responsive clean coatings. Nature makes use of a range of fascinating surface properties, such as the leaves of the Lotus plant which stay clean even in dirty environments. In this project we will explore the molecular properties of novel polymer coated surfaces that-similar to some natural surfaces-can adapt to changing environmental stimuli and be resistant to contamination. Specifically, we aim to develop self-cleaning polymer coatings which can reversibly switch from wettab ....Environmentally responsive clean coatings. Nature makes use of a range of fascinating surface properties, such as the leaves of the Lotus plant which stay clean even in dirty environments. In this project we will explore the molecular properties of novel polymer coated surfaces that-similar to some natural surfaces-can adapt to changing environmental stimuli and be resistant to contamination. Specifically, we aim to develop self-cleaning polymer coatings which can reversibly switch from wettable to non-wettable with changing temperature and humidity. These self-cleaning polymer surfaces with environmentally responsive properties will add value to pre-painted steel products and other coatings.Read moreRead less

Mathematical and computational models for agrichemical retention on plants. This project aims to build interactive software that simulates agrichemical spraying for multiple virtual plants reconstructed from scanned data. Mathematical modelling and computer simulation could offer an alternative to expensive experimental programs for agrichemical spraying of plants. This project will use contemporary fluid mechanics to build practical mathematical models for droplet impaction, spreading and evaporation on leaf surfaces, and experimentally calibrate and validate the models. The software is expected to drive the development of agrichemical products that increase retention, minimise environmental impacts, and reduce costs for end-users.Read moreRead less

Integrating microbiology and climatic drivers to determine triggers for nitrous oxide emissions from arable soils in semi-arid Western Australia. Increasing nitrous oxide emissions from soil to the atmosphere are a concern as they contribute to global warming and the destruction of the ozone layer. While 70-81% of this increase has been attributed globally to agricultural soils, the factors controlling emissions from arable soils in southern Australia are not well understood.

Increasing nitrous oxide emissions from soil to the atmosphere are a concern as they contribute to global warming and the destruction of the ozone layer. While 70-81% of this increase has been attributed globally to agricultural soils, the factors controlling emissions from arable soils in southern Australia are not well understood. We aim to characterise and model the relationship between the soil microbial community responsible for nitrous oxide emissions and soil water availability. Understanding the processes responsible for nitrous oxide emissions will enable us to change the way we manage our semi-arid soils so as to minimise nitrous oxide emissions.Read moreRead less
