Risk assessment modelling for corrosion affected concrete infrastructure. Aging and deterioration of physical infrastructure is a global problem that has caused widespread premature structural failures and significantly reduced its designed service life. This is an increasing problem also for Australia. For reinforced concrete infrastructure, the corrosion of the reinforcing steel within the surrounding concrete is the most significant factor. The aim of the project is to improve understanding o ....Risk assessment modelling for corrosion affected concrete infrastructure. Aging and deterioration of physical infrastructure is a global problem that has caused widespread premature structural failures and significantly reduced its designed service life. This is an increasing problem also for Australia. For reinforced concrete infrastructure, the corrosion of the reinforcing steel within the surrounding concrete is the most significant factor. The aim of the project is to improve understanding of the factors that influence corrosion mechanics in marine environments, to re-examine corrosion process in practical concrete structures and to develop a model for corrosion to enable prediction of structural deterioration and improved risk assessment.Read moreRead less
TiO2 nanoparticle design and photocatalysis applications. The aim is to design nanosized TiO2 photocatalsysts with superior photoactivity using various synthesis paths. Nanosized TiO2 particles will be prepared using sol-gel, aerosol and plasma processing, their physical and chemical properties will be closely studied and their photocatalytic ability will be assessed. Such tailor-made photocatalysts have significant commercial potential value, as they would be highly suitable for the photooxidat ....TiO2 nanoparticle design and photocatalysis applications. The aim is to design nanosized TiO2 photocatalsysts with superior photoactivity using various synthesis paths. Nanosized TiO2 particles will be prepared using sol-gel, aerosol and plasma processing, their physical and chemical properties will be closely studied and their photocatalytic ability will be assessed. Such tailor-made photocatalysts have significant commercial potential value, as they would be highly suitable for the photooxidation of organic compounds and the photoreduction of metal ions in wastewaters. Findings from this work will pave the way for a "green" technology such as photocatalysis to become more efficient and hence a competitive alternative to conventional water treatment methods.Read moreRead less

Structural and multidisciplinary optimization. Structural and multidisciplinary design optimization is an important subject in aeronautical, aerospace, automobile, offshore platforms and many other structures. This project aims to address design optimization of coupled structures, with a focus on electro-mechanical coupled structures. It is expected to coordinate an integrated effort to develop efficient and effective algorithms for optimum design of electro-mechanical coupled structures.
Stuctural analysis of RNA polymerase elongation complexes. RNA polymerase (RNAP) is an essential enzyme in all living cells. Its role is to convert the genetic information stored in genes into a message that can be converted into protein. Many additional factors are required to ensure that this enzyme functions correctly in the cell. The aim of this project is to obtain structural information on a bacterial RNAP complexed with an essential transcription factor called NusA. Using this information ....Stuctural analysis of RNA polymerase elongation complexes. RNA polymerase (RNAP) is an essential enzyme in all living cells. Its role is to convert the genetic information stored in genes into a message that can be converted into protein. Many additional factors are required to ensure that this enzyme functions correctly in the cell. The aim of this project is to obtain structural information on a bacterial RNAP complexed with an essential transcription factor called NusA. Using this information, plus data already obtained on the structure of this enzyme complexed with another essential factor called sigma, we will design small molecules to inhibit the interaction of these essential factors with polymerase. These molecules will serve as leads for the development of new antibiotics.Read moreRead less
Developing the Helium Atom Pinhole Camera. The tantalising possibility of an optical instrument that uses neutral atom beams to image surfaces, rather than light or electrons, has been a grand challenge in Physics ever since de Broglie first postulated the existence of matter waves . This project seeks to realise this seminal goal using an elegantly simple design based on the concept of a pin hole camera. The successful development of this world-first instrument would represent a significant adv ....Developing the Helium Atom Pinhole Camera. The tantalising possibility of an optical instrument that uses neutral atom beams to image surfaces, rather than light or electrons, has been a grand challenge in Physics ever since de Broglie first postulated the existence of matter waves . This project seeks to realise this seminal goal using an elegantly simple design based on the concept of a pin hole camera. The successful development of this world-first instrument would represent a significant advance in helium atom microscopy and would significantly enhance the reputation of Australian science. Moreover, this project strengthens and supports a key collaboration between the Universities of Newcastle and Cambridge and is at the core of this emerging technology.Read moreRead less

Advanced materials such as the conducting polymer and applications of these materials at the nanoscale and up is clearly a cutting edge area of international interest. Development of readily processable nano systems has been a challenge with a clear scientific and commercial benefit. This proposal will bring linkages to Australia with the world leader in the field, Professor Kaner -UCLA, on the synthesis of polyaniline nanofibres and associated photowelding processes. The opportunities to Australia and the USA will be to expand the potential utility of such systems, which without such interactions would permit others to take a stake hold in this emergent and potentially lucrative technology.Read moreRead less
