The project aims to address a growing problem of increasing energy consumption by storing intermittent energy from the sun in affordable and efficient flow batteries. The project expects to generate new knowledge in the areas of materials science and battery research by using innovative theoretical chemistry approaches to studying electrochemical properties of nitroxide radicals in ionic media. The project aims to develop radical organic flow batteries by utilising ionic liquids to stabilise radicals. Intended outcomes of the project include improved efficiency of flow batteries that can store energy from widely used solar panels. This should provide significant benefits to Australia’s effort to switch to renewable energy technologies. Read moreRead less
The role of hypohalous acids and related oxidants in the oxidative damage of biological systems: a computational investigation. The aim of this project is to decipher the molecular mechanisms of key reactions involved in oxidative damage to biomolecules. The study will lead to a better understanding of oxidative stress in biological systems and its role in chronic inflammatory disease, heart disease, and cancer.

The project will address a major challenge in biochemistry: how to design antioxidants that effectively scavenge harmful free radicals. This will involve the use of state-of-the-art quantum chemistry calculations to determine the molecular mechanisms of natural antioxidants and to design artificial antioxidants with higher efficacy. This project will introduce new concepts and methodologies that build on recent breakthrough research, revealing a novel mechanism of action of natural antioxidants. This will unravel the reaction mechanisms underlying defence against radical damage to key biomolecules, and will allow the design of bioinspired antioxidants for the treatment of oxidative-damage related diseases that affect millions of people.Read moreRead less

Summary
About half of all patients Treated with an operation to remove their prostate cancer have a high chance of the cancer coming back. Giving immediate radiotherapy to all patients will improve cure rates but does not benefit all men and can cause significant side effects. This study explores whether it is safe to wait and only give radiotherapy when there is a rising PSA after surgery indicating active cancer. A total of 470 men from Australasia will enter this study comparing the two approaches.

Summary
Metal ions such as iron and copper have been reproted to be present in the lesions present in diseased human arteries and it has been suggested that these metal ions contribute to the development of atherosclerosis (hardening of the arteries) via their ability to catalyse the formation of highly reactive molecualr fragments called free radicals. Though metal ions are known to catalyse such reactions in test-tube experiments, both the presence of metal ions in diseased arteries and their ability ....Metal ions such as iron and copper have been reproted to be present in the lesions present in diseased human arteries and it has been suggested that these metal ions contribute to the development of atherosclerosis (hardening of the arteries) via their ability to catalyse the formation of highly reactive molecualr fragments called free radicals. Though metal ions are known to catalyse such reactions in test-tube experiments, both the presence of metal ions in diseased arteries and their ability to generate free radicals is controversial. This study will employ a novel, minimally-invasive, technique to assess the nature and quantity of metal ions present in well-defined human and animal lesions at different stages of lesion development. The ability of these metal ions to catalyse free radical formation from components present in the artery wall will also be assessed. The release of these metal ions from the artery wall to added organic molecules will be assessed as this might minimise their potential to cause damage, and provide a possible therapeutic strategy. These studies will therefore provide valuable information as to the significance and role of reactive metal ions in the development of human artery disease and the possible prevention, or minimisation, of such processes.Read moreRead less
Electronic and Optical Properties of Doped Titanium Dioxide. Titanium dioxide, is widely used as a white pigment, owing to its high refractive index, second, only after diamond. Yellowing of rutile pigment particles, observed on prolonged exposure to sunlight, is a serious problem that pigment manufacturers would like to overcome. It is proposed that aluminium-doping of rutile limits this discolouration by altering the electronic structure of the rutile particles. This project seeks to identify ....Electronic and Optical Properties of Doped Titanium Dioxide.

Yellowing of rutile pigment particles, observed on prolonged exposure to sunlight, is a serious problem that pigment manufacturers would like to overcome. It is proposed that aluminium-doping of rutile limits this discolouration by altering the electronic structure of the rutile particles. This project seeks to identify the specific electronic cause of the yellowing process, the nature of the Al defect,it's effect on the electronic structure of rutile, and the electronic perturbations that may occur when other dopants are used.Read moreRead less

The scientific benefits would flow, in the first instance, to the large national and international communities of scientists whose research makes use of the results of X-ray diffraction experiments. Applications of the research to amino acids and peptides will benefit investigations into the structure and molecular dynamics of biological systems, including proteins and enzymes. Studies of charge densities in crystals will obtain a standard tool for improved modelling of molecular motion, resulting in physically more realistic charge density functions, and hence greater insight into the relationship between properties of crystals and their constituent molecules.Read moreRead less
