3D-printed cellular structures for bone biomimetic implants

Bone implants have been increasingly used to repair and replace the host bones. One promising approach is creating three-dimensional (3D) porous cellular structures that provide suitable microenvironments to achieve the required integration and support under loading conditions.Both porosity and pore size have a direct influence on their functionalities for biomedical applications. Besides the intrinsic material properties of the polymers, the internal architecture of a cellular structure has a significant effect on its mechanical and biological behaviour.Improved specific mechanical properties have …

Glassy 2D molecular materials

Modern semiconductor technologies are based on crystalline materials with well-defined physical and electronic structures.However, molecular materials, such as organic semiconductors, may present interesting opportunities through disordered structures.The focus of this project will be on conjugated 2D materials without long-range order: molecular glasses. Through control of the chemical composition, atomic bonding motifs, and lateral size, we will be able to modify the properties of these materials.Our focus will be on synthesising and studying these new materials to better understand the relationship …

New 2D heterostructures on silicon carbide for two dimensional electronics

Graphene has attracted a great deal of interest due to its remarkable electronic, optical and mechanical properties. However the absence of a bandgap limits its use in many applications.Future applications in nanoelectronics will depend critically on the development of novel approaches to introduce a bandgap while preserving carrier mobility. An example includes stacking graphene with other two-dimensional (2D) materials with complementary properties.This project will look at systematically refining the integration of different 2D materials with graphene grown epitaxially on silicon …

Materials discovery and design from quantum mechanics-based computational approaches

Understanding novel physics in nanoscale materials is critical for the development of modern electronics technology.However, such delicate materials are difficult to manipulate and characterize experimentally because of their tiny size. This raises the conundrum of how to proceed forward quickly with exploration and subsequently design of properties.In principle, materials properties are determined by the electronic structure. Quantum mechanics based computational approaches are able to address fundamental electronic, optical and magnetic properties in such materials.This provides a powerful complement to the …

2D heterostructures for future electronics

The traditional approach to the miniaturisation of electronic devices is coming to a halt. Experts agree that the Moore’s law prediction of doubling the number of transistors per chip every two years will cease to be fulfilled in 2020, as the heat produced in small structures cannot be cooled down quickly enough.However, by reducing the size of the device, the quantum nature of atoms and solids can be turned into an asset. By exploiting the phenomena occurring at these scales, …

Tailoring 2D materials via interface engineering

2D materials are crystalline materials with only a single layer thickness. The best known 2D materials is graphene, but it also encompasses a large family of materials , such as transition metal dichalcogenides (TMDCs).2D materials are set for breakthroughs in fundamental research and transformative technologies. They have few surface dangling bonds and unique atomic-level uniformity which make them very appealing for developing optical, electronic and energy applications.These materials also bring a new degree of freedom to combine highly distinct materials, …

Mitigating vehicular crashes into masonry structures using innovative damping technologies at wall edges

With population increases in major cities accompanied by increase in vehicles on road and waterways, structures such as columns in buildings and bridges as well as walls in buildings that are adjacent to the roads or waterways become vulnerable to vehicular crashes. These impacts cause damage or failure to the structure and injuries/deaths to passengers and users of the structure.This project will evaluate the vulnerability of one of those structures to credible vehicular crash and the effects of controlling parameters. …

Mitigating vehicular crashes into masonry structures using innovative materials technologies at impact zone

Our structures are normally not designed for random and extreme loadings such a vehicular impacts. Buildings and their columns at road frontages and bridge piers are vulnerable to vehicular impacts which result in extensive property damage, harm to people and disruption of normal lives.This project will consider the use of new materials technology and advanced modelling techniques to design critical members of buildings and bridges, or to retrofit existing vulnerable walls and columns in order to mitigate the adverse effects …

Adaptive evolution of anaerobic methanotrophic (ANME) archaea mediating methane oxidation in freshwater environments

The as-yet-uncultured archaeal lineage Methanoperedenaceae are anaerobic methanotrophs with a key role in mitigating the atmospheric release of methane in freshwater environments. The metabolic diversity of these microorganisms directly links methane with several key biochemical cycles and suggests a remarkable ability of these microorganisms to adapt to diverse environmental conditions. The overall aim of this PhD project will be to uncover the metabolic diversity of the Methanoperedenaceae and to understand the evolutionary mechanisms responsible for these adaptations.Approaches/skills and techniquesThe project …

Understanding fundamental differences in novel Yarrowia lipolytica strains and their ability to utilise lipid-rich wastewaters

Yarrowia lipolytica is a yeast that is capable of using a host of lipids as a carbon source. The yeast is used for equine and pet food supplements and holds great promise a probiotic and nutritional supplement.We have six unique Australian strains that need to be characterised and compared using various omics platforms. Additionally, growth in various lipid-rich aqueous wastewaters will be compared. Wild type strains will also be genetically altered to develop strains with improved growth and substrate utilisation …
