The project aims at advancing the synthetic limits and broadening the synthetic scope of living free radical polymerization and thus enhancing the library of polymer structures available for applications ranging from drug delivery to opto-electronics. Current material design for these applications is yet to reach its full potential through innovative synthetic approaches. The proposal critically underpins and further advances Australia's leading position in both breakthrough science as well as advanced materials. Due to its significant scientific breadth and large coverage of both synthetic and physical aspects of polymer science, the project also provides a significant platform for research training at both honours and PhD level.Read moreRead less
Catalytic conversion of Australia's natural gas to value added products. While natural gas (of which methane is the primary component) is an abundant source of energy, it is normally found in remote areas and for its successful exploitation it needs to be processed. The processing usually requires significant energy and resources input. In this project we will develop a fundamental understanding to a single step catalytic process that can utilise natural gas and nitrous oxide (both potent greenh ....Catalytic conversion of Australia's natural gas to value added products. While natural gas (of which methane is the primary component) is an abundant source of energy, it is normally found in remote areas and for its successful exploitation it needs to be processed. The processing usually requires significant energy and resources input. In this project we will develop a fundamental understanding to a single step catalytic process that can utilise natural gas and nitrous oxide (both potent greenhouse gases) and oxygen to produce selectively methanol and hydrocarbons from a natural gas feedstream in a controlled manner. A single step process for natural gas conversion utilising waste green-house gases is expected to be of great benefit to the Australian economy, environment and energy securityRead moreRead less
Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper bound ....Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper boundary conditions for viscoelastic flow at interfaces between a flowing fluid and a solid surface. This vital area has not been thoroughly studied theoretically and computationally, and we seek to clarify the mechanisms by using molecular dynamics.Read moreRead less
Polymerization Mechanism and Kinetics of 1,1-Disubstituted Monomers. This project focuses on two exciting research areas: (I) we have found that an oxygen atom b to the double bond activates radical polymerization, making a whole new family of polymeric structures accessible, and (II) we have strong preliminary data that demonstrates a very large solvent effect on propagation and termination reactions for acrylic monomers with an a-CH2OH functionality, suggesting that significant control can be ....Polymerization Mechanism and Kinetics of 1,1-Disubstituted Monomers. This project focuses on two exciting research areas: (I) we have found that an oxygen atom b to the double bond activates radical polymerization, making a whole new family of polymeric structures accessible, and (II) we have strong preliminary data that demonstrates a very large solvent effect on propagation and termination reactions for acrylic monomers with an a-CH2OH functionality, suggesting that significant control can be exerted over the polymerization process using additives. Additionally, we demonstrate that polymers containing repeat units with an a-CH2OH functionality can undergo reversible cyclization, enabling a whole range of novel functional materials.Read moreRead less

The proposed project combines two exciting research areas, namely the chain length dependencies of kinetic coefficients and reversible addition fragmentation chain transfer (RAFT) polymerisations. The starting point of the project will be a novel technique recently invented by our team for termination rate measurement utilizing the RAFT process. Detailed knowledge of chain length dependent rate coefficients in both homo- and copolymerisations is essential from both an academic and industrial perspective, because polymerisation kinetics not only govern the reaction rates but influence directly the polymeric material properties.Read moreRead less
