Understanding of structure development in drying droplets through the stickiness paradigm. The aims of this research are to develop a new model for multicomponent droplet drying. This model will provide predictions of conditions where composition variation exists in the drying particles. Validation of the model will be made using a novel instrument to measure the in-situ development of surface stickiness during drying.

The aims of this research are to develop a new model for multicomponent droplet drying. This model will provide predictions of conditions where composition variation exists in the drying particles. Validation of the model will be made using a novel instrument to measure the in-situ development of surface stickiness during drying. Stickiness is an important issue encountered during drying and handling of some key food and consumer materials. Currently, there is no technique to measure the evolution of stickiness during drying. Key outputs will include the model, the instrument, and the development of efficient methods to generate the multicomponent data.Read moreRead less
Evolution of Contact Damage in Layer Structures. Brittle layer structures (eg brittle coating on ceramic substrate) can be much more damage tolerant than their constituent material components - cracks tend to remain contained within the coating. Very little is known about the factors that control this behaviour. This project will exploit unique local expertise in modelling damage evolution to fill a niche in a large study being carried out at the National Institute of Standards (NIST) in the U ....Evolution of Contact Damage in Layer Structures. Brittle layer structures (eg brittle coating on ceramic substrate) can be much more damage tolerant than their constituent material components - cracks tend to remain contained within the coating. Very little is known about the factors that control this behaviour. This project will exploit unique local expertise in modelling damage evolution to fill a niche in a large study being carried out at the National Institute of Standards (NIST) in the U.S.A. An understanding of the factors that maximise the containment of cracks is essential to the design and development of the next generation of advanced layer composites for many biomechanical and other engineering applications.Read moreRead less

Mechanisms of Ammonium Nitrate Decomposition and Stability of Industrial Explosives in Reactive Mining Grounds. This project is designed to probe reaction mechanisms of ammonium nitrate based explosives with pyritic shales commonly found in overburdens of mineral deposits, and to study the influence of various factors, such as mineralogical characteristics, carbonaceous materials, weathering, pH values and application of various inhibition agents, on the decomposition and stability of ammonium n ....Mechanisms of Ammonium Nitrate Decomposition and Stability of Industrial Explosives in Reactive Mining Grounds. This project is designed to probe reaction mechanisms of ammonium nitrate based explosives with pyritic shales commonly found in overburdens of mineral deposits, and to study the influence of various factors, such as mineralogical characteristics, carbonaceous materials, weathering, pH values and application of various inhibition agents, on the decomposition and stability of ammonium nitrate. Ammonium nitrate crystallisation, which significantly reduces the stability of emulsion explosives, will be examined using both chemical and microscopic tools. The outcomes of this research will provide a scientific basis that underpins the development of safe and cost-effective explosives for applications in dangerous reactive mining grounds.Read moreRead less

The proposed grant aims to establish an integrated facility for characterising and researching fine and ultrafine particles. It will serve various research groups of three collaborating universities. Current facilities are limited to characterisation of liquid-borne particles down to 10 nm size. To extend the groups research interests into aerosols and nanoparticles the facilities requested in this grant are essential. Equipment critical for research into catalytic processes is also requested. Integration of the groups will create a force that institutions and industries,nation-wide, can turn to when the need for competent analytical and research solutions for particles and catalysis arises.Read moreRead less
Predicting cell wall mechanics from structure in a materials engineering approach to plant growth. The project fosters a novel, interdisciplinary approach to understanding how the structure of plant cell walls determines their mechanical properties.

The project fosters a novel, interdisciplinary approach to understanding how the structure of plant cell walls determines their mechanical properties. Such understanding requires combining biological and engineering approaches and will illuminate how plants grow and produce cells and organs with particular shapes. This is scientifically important but is also important for industries depending on specialised cell shapes such as those of cotton and wood fibres. Our work will improve our understanding of how wall structure determines fibre and other cell shapes and give us tools which can be used to understand how final wall structure determines the fibre mechanics on which industrial users depend.
