It is important to improve the quality of their Talcom body powder, baby powder and other cosmetic products involving talc. The areas that can and need to be improved are shining characteristics, assessing the slip properties as well as developing the cosmetic chemistry of talc and other additives. The proposed project will generate: a) simple but reliable test methods for measuring slip and shine, b) methods for control of the physical and chemical characteristics of talc blends, c) mathematical model(s) for property and process control, which is useful to improvement of the final talc properties and in-use service.Read moreRead less
Polymers for Novel Surfactants. The aim of the proposed research is to develop novel surface-active polymers with complex architectures and more efficient strategies for the synthesis of surface-active polymers in general. We will exploit the polymerization characteristics of the novel catalytic chain transfer and radical addition-fragmentation transfer polymerization techniques to achieve polymerization control that has been virtually impossible hitherto. The proposed research will thus make ....Polymers for Novel Surfactants. The aim of the proposed research is to develop novel surface-active polymers with complex architectures and more efficient strategies for the synthesis of surface-active polymers in general. We will exploit the polymerization characteristics of the novel catalytic chain transfer and radical addition-fragmentation transfer polymerization techniques to achieve polymerization control that has been virtually impossible hitherto. The proposed research will thus make accessible a wide range of novel surface-active polymers that have been impossible to synthesise to date, and which we expect to be more efficient and hence leads to greener technologies.

Water at Hydrophobic Surfaces. The properties of water define the nature of life on this planet. When water encounters a hydrophobic surface - at the air/water interface, in contact with unreactive solids such as Teflon, or at an oil drop, our recent experiments indicate that the water dissociates more readily into protons and hydroxide ions - undergoes autolysis - than in bulk water. Furthermore, the hydroxide ions are preferentially adsorbed at the surface, giving it a negative charge. This pr ....Water at Hydrophobic Surfaces.

When water encounters a hydrophobic surface - at the air/water interface, in contact with unreactive solids such as Teflon, or at an oil drop, our recent experiments indicate that the water dissociates more readily into protons and hydroxide ions - undergoes autolysis - than in bulk water. Furthermore, the hydroxide ions are preferentially adsorbed at the surface, giving it a negative charge. This project will test the generality and implications of this novel concept. The results will range across physics, chemistry, biology and their associated technologies, a consequence of the ubiquitous importance of water. Read moreRead less
Sustainable surfactants from Australian oilseeds. This project aims to develop a new generation of sustainable surfactants utilising Australian-grown oilseed feedstocks. These molecules are designed to replace current materials made from petroleum and palm oil, to fulfil a key role as the next generation of bio-resourced detergents and emulsifiers.

This project aims to develop a new generation of sustainable surfactants utilising Australian-grown oilseed feedstocks. These molecules are designed to replace current materials made from petroleum and palm oil, to fulfil a key role as the next generation of bio-resourced detergents and emulsifiers. The work seek to develop a library of new molecules to better understand the relationship between molecular structure and performance, through cutting edge lab testing and utilising national infrastructure, guiding the use of new components in formulating new products. It is anticipated that the surfactants generated will find uses in household cleaning and personal care products, providing high value chemicals from key Australian crops.Read moreRead less

Understanding and Controlling Wall Deposition in Spray Dryers via Experimental and Computational Fluid Dynamics (CFD) Studies. A key problem in operating spray dryers for producing milk powders and other consumer products, such as detergents, is the occurrence of internal wall deposits of powder, leading to thermal degradation of the products and potential fire hazards. However, no fundamental theory has been applied in spray dryers to allow this process to be controlled. The proposed project wi ....Understanding and Controlling Wall Deposition in Spray Dryers via Experimental and Computational Fluid Dynamics (CFD) Studies. A key problem in operating spray dryers for producing milk powders and other consumer products, such as detergents, is the occurrence of internal wall deposits of powder, leading to thermal degradation of the products and potential fire hazards. However, no fundamental theory has been applied in spray dryers to allow this process to be controlled. The proposed project will use state-of-the-art experimental and computational techniques to gain a fundamental understanding of this phenomenon and will develop a validated wall deposition model to predict when and to what extent this process occurs, to give higher throughputs and/or more efficient systems.Read moreRead less
Synthesis of stimuli-responsive star polymers for controlled drug delivery. The project aims to prepare novel star polymers suitable for drug delivery via controlled radical polymerization techniques. Such star polymers can be employed to release drugs within the human body in a controlled manner over time and are thus able to target specific sites, i.e. a tumor. The release characterisitics are be influenced by the structure and the size of the star polymer, which can easily be altered via cont ....Synthesis of stimuli-responsive star polymers for controlled drug delivery.

The release characterisitics are be influenced by the structure and the size of the star polymer, which can easily be altered via controlled radical polymerization techniques. These novel stars are expected to improve the release kinetics of the drug comparing to similar structured micelles due to their higher stability upon injection.Read moreRead less

De-risking new surfactant and polymer classes in personal care formulations. Personal care products are almost completely reliant on palm oil feedstocks for the surfactants or soaps that provide cleansing and conditioning. Yet, there is considerable risk in moving to alternative feedstocks for new surfactant formulations, where the design rules based in fundamental colloid science do not yet exist. In collaboration with world leading formulation expertise, this project aims to use a combination ....De-risking new surfactant and polymer classes in personal care formulations. Personal care products are almost completely reliant on palm oil feedstocks for the surfactants or soaps that provide cleansing and conditioning. Yet, there is considerable risk in moving to alternative feedstocks for new surfactant formulations, where the design rules based in fundamental colloid science do not yet exist. In collaboration with world leading formulation expertise, this project aims to use a combination of high-throughput microfluidic platforms to direct more detailed colloidal, surface and scattering techniques to drive mechanistic studies to link microstructure to formulation properties. This will lead to the design rules needed to control the synergistic interactions between surfactants and polymers in these formulations.Read moreRead less
