Designer Surfactants for Creation of Emulsion Properties. We propose new approaches to the design of surfactants for stabilising water in oil emulsions. New block copolymer surfactants may be "tailored" for head group structure and a pre-chosen hydrophilic/lipophilic balance at the oil-water interface using the Australian developed RAFT polymer synthesis method and polymeric inorganic species. The proposers have an extensive background in these areas.

The proposers have an extensive background in these areas.
X-ray and neutron scattering techniques, developed by us, allow the interfacial structure of the surfactant to be found and the intellectual "loop" closed in the design process. Preliminary screening will be done using the surface balance and bulk emulsion synthesis.Read moreRead less
High Internal Phase Emulsions - Structure and Rheology Control. Our first SPIRT Grant with ORICA Australia Ltd has successfully identified nanostructures in high internal phase emulsions which confer useful stability and robustness on these industrially important systems. The aim now is to ramify those discoveries both scientifically and technologically in the design of emulsion structure using our, now established, techniques. In particular, the objective is to control both nanoscale and mes ....High Internal Phase Emulsions - Structure and Rheology Control. Our first SPIRT Grant with ORICA Australia Ltd has successfully identified nanostructures in high internal phase emulsions which confer useful stability and robustness on these industrially important systems. The aim now is to ramify those discoveries both scientifically and technologically in the design of emulsion structure using our, now established, techniques. In particular, the objective is to control both nanoscale and mesoscale structure in emulsion formulation, as well as the rheology and stability of emulsion preparations. To do this we plan to use mixed surfactant systems and to study intersurfactant synergic effects on the structure and fluidity of the interfacial material. We believe that the proposed work is unique and that the outcomes will be scientifically novel and also valuable for Australian industry.Read moreRead less
Characterisation of nanobubbles. Surprisingly, nano-sized bubbles have recently been found to exist in aqueous solutions. Classical theory tells us they should rapidly dissolve, yet they are stable for several days, a phenomenon which has only recently been explained. Despite this, nanobubbles are already used in cleaning processes and appear to have significant health benefits. They are being investigated in treatments for asthma and neurodegenerative diseases. In collaboration with a pharmaceu ....Characterisation of nanobubbles. Surprisingly, nano-sized bubbles have recently been found to exist in aqueous solutions. Classical theory tells us they should rapidly dissolve, yet they are stable for several days, a phenomenon which has only recently been explained. Despite this, nanobubbles are already used in cleaning processes and appear to have significant health benefits. They are being investigated in treatments for asthma and neurodegenerative diseases. In collaboration with a pharmaceutical company, the best means to produce and characterise nanobubbles will be investigated, as well as the conditions governing their stability. The project also aims to determine how the nanobubbles interact with surfaces in order to better control their properties and achieve a better understanding of these bubbles.Read moreRead less

Chemical Synthesis and Biological Evaluation of Analogues of Platencin, a New-generation Antibiotic. The just discovered natural product platencin displays potent and broad spectrum anti-bacterial activity. It may represent the precursor of a new class of drugs to replace current anti-infective agents which are becoming alarmingly less effective as bacterial resistance increases dramatically. For this reason, platencin has been described as a once in a generation discovery. This study will explo ....Chemical Synthesis and Biological Evaluation of Analogues of Platencin, a New-generation Antibiotic. The just discovered natural product platencin displays potent and broad spectrum anti-bacterial activity. It may represent the precursor of a new class of drugs to replace current anti-infective agents which are becoming alarmingly less effective as bacterial resistance increases dramatically. For this reason, platencin has been described as a once in a generation discovery. This study will exploit two sophisticated new synthetic techniques for the purposes of making analogues of platencin that will be screened by the industry partner, Biota, for anti-bacterial properties. New drug candidates capable of treating especially dangerous infections such as methicillin resistant staphyllococcus aureus (MRSA) should thus emerge.Read moreRead less

Next-generation latent fingermark detection using functional nanomaterials. This project aims to develop a nanotechnology-based fingermark detection technique applicable in standard police laboratories and crime scenes. Current methods only detect half the fingermarks on an object, so many criminals are not identified. This project will use silicon oxide nanoparticles with a luminescent dye to target fingermark secretion components and address interference from substrate chemistries and background luminescence. Moving away from traditional detection methods is expected to improve law enforcement outcomes, as fingermarks that current technologies cannot detect will be visualised for the first time.Read moreRead less
Oxidation product generation during heating and storage of bio-fuels and alternative fuels assessed by multidimensional gas chromatography. Renewable bio-fuels offer much promise as a replacement for fossil fuels. However, they have a tendency to oxidise when prepared and used, potentially forming gums and solid deposits in engines. The objective of this project is the identification of these deposits and subsequent prevention during engine operation.
