In order to meet this critical demand, it is crucial to devise ways to transform light energy into chemical fuels. This project aims to create novel nanostructures that directly couple light energy into chemical reactions. This will be achieved by the creation of metallic nanoparticles that can transform light energy into hot electrons: entities that can efficiently drive the production of chemical fuels in a process similar to that of photosynthesis.Read moreRead less

Summary
The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells ....The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells use epigenetic changes to help control how they grow and develop. Evidence suggests a direct link between diet and environmental influences on our epigenetic profile. Recent research has traced the origins of many of the health problems of adult life back to the earliest periods of development _ to the time spent in the womb and the first few years of life. If we are born with a low birth weight, we are more likely to get sick later in life. Overwhelming evidence exists that the environment in the womb is critical for a healthy birth weight (and health in later life) and it is thought that epigenetics may be the missing link between this environment, low birth weight, and therefore health in later life. In addition, mounting evidence supports a general link between epigenetic de-regulation and predisposition to disease. However, the timing and the overall contribution of environmental- genetic influences to the establishment of faulty epigenetic markings remain largely unknown. Twins are the best model to study this link as they share similar (but not identical environments) and some share identical genetic makeup. Using twins, Dr Jeffrey Craig and his team will investigate the factors in the prenatal environment that modify specific cells, leading to low birth weight and increase disease risk later in life. They predict that this occurs via specific changes in gene activity caused by epigenetic disruption.Read moreRead less
Nanofabrication of Metamaterials for Next Generation Optical Devices. The dream of invisibility cloaks dates back to ancient times but recent advances in nanotechnology have made this a reality through the use of metamaterials. Metamaterials are artificially-made materials that have optical properties not found in nature. This field is still in its infancy and significant challenges remain and need to be solved before practical applications can be realised.

The dream of invisibility cloaks dates back to ancient times but recent advances in nanotechnology have made this a reality through the use of metamaterials. Metamaterials are artificially-made materials that have optical properties not found in nature. This field is still in its infancy and significant challenges remain and need to be solved before practical applications can be realised. This project builds on Australia’s strategic investment in nanofabrication capabilities to fabricate functional metamaterials and uncover the underlying physical phenomena. It will revolutionise the field of nanophotonics for a variety of novel applications ranging from defence, renewable energy, imaging, sensing to optical communications.Read moreRead less

Hematite (iron oxide) is a promising electrode material for photoelectrochemical hydrogen generation from water. It has low cost, good long-term stability and absorbs light efficiently. However, its use is limited by its poor electrical conductivity. This project aims to develop a novel host-guest nanostructure that exploits the beneficial light-absorption properties of hematite (the guest) but shifts the charge transport function to a nanostructured transparent conductive oxide host. The project aims to produce nanostructured hematite electrodes for efficient hydrogen production from water and sunlight, thus making a significant contribution to the goal of commercially-viable storage of solar energy in the form of hydrogen.Read moreRead less
