Optimum design of controlled drug delivery systems. Controlled drug delivery systems are ideal to achieve localised release of drugs at an effective rate for a prolonged period. They have the merit of optimising drug absorption by a body, relieving patients from frequent administration and high dosage of drugs which often result in drug wastage, patients' inconvenience and more importantly the side effects that can be fatal. The success of this project will (1) enhance the Australia pharmaceutic ....Optimum design of controlled drug delivery systems. Controlled drug delivery systems are ideal to achieve localised release of drugs at an effective rate for a prolonged period.

Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, whic ....Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, which appears thus to be an inherent property of the polymer, the project aims at formulating new hypotheses to explain this phenomenon, and to confirm them experimentally. The "chelation" hypothesis will be validated by modifying the structure of polymers, and the "spontaneous precipitation" hypothesis by assessing the effect of solutes on the equilibrium water content of polymers. NMR and FTIR spectrometric techniques will be used to gain further insight into the mechanism of calcification. Methods to prevent the calcification will potentially result from these experiments, however, anticalcification agents will also be incorporated into hydrogels and their effect evaluated in calcification assays.Read moreRead less

It holds one-third of the world's uranium reserves and is a major player in the development of technology for immobilizing radioactive waste. We will use computer simulation to answer a very important question which is extremely difficult to study experimentally: How does radioactive decay inside a solid change the chemistry of the material over time? Not only will our study improve nuclear waste storage, it will also reveal how in-situ chemical change creates new kinds of solids which cannot be made by conventional means. These solids can exhibit unusual and useful behaviour; this project provides the first investigation of this unexplored technological niche.Read moreRead less
