This project aims to develop innovative metaconcrete for structural protection by utilising the concept of phononic crystals and metamaterials which has been recently developed by physicists. Traditional construction materials are used in new structural forms to mitigate dynamic loading effects by exploiting the unique characteristics of the proposed metaconcrete. Theoretical, numerical and experimental methods will be used to derive the best performing metaconcrete and verify its static and dynamic load resistant capacities. The expected outcomes of the project will lead to innovative extreme-loading resistant designs and provide significant benefit to the Australian construction industry, general public and economy.Read moreRead less
Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little ....Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little is known about the technology. This project will model the behaviour of rubber soil in order to introduce it as an environmentally sustainable, cost-effective and technically sound choice of geomaterial for both standard and non-standard geotechnical structures.Read moreRead less

This project aims to efficiently separate helium from methane and nitrogen via the layered two dimensional materials. This project will seek to understand the assembling behaviour of these nano-sized Mxene flakes and their molecular sieving properties. Australia is playing a leading role in the global liquefied natural gas (LNG) production and trade.

Are two processes one too many? An investigation of the viability of the dual-process model of recognition memory. Memory is the glue that holds together our lives and personal identities. While psychologists are developing better and more sophisticated accounts of how it works, many deep questions remain. The present research examines some of these questions in relation to how memory can be decomposed into its component processes and how we are to understand these processes. An appropriate unde ....Are two processes one too many? An investigation of the viability of the dual-process model of recognition memory. Memory is the glue that holds together our lives and personal identities. While psychologists are developing better and more sophisticated accounts of how it works, many deep questions remain. The present research examines some of these questions in relation to how memory can be decomposed into its component processes and how we are to understand these processes. An appropriate understanding of these questions is vital to the development of interventions (both psychological and pharmacological) designed to halt or even reverse memory decline associated with normal aging and age-associated brain disease (such as Alzheimer disease).Read moreRead less

Reducing geotechnical design conservatism to secure floating wind energy. The next frontier for offshore wind energy is moving further out to sea to avail of stronger and more consistent wind speeds. In these water depths, wind turbines are installed on floaters tethered to anchors in the seabed.

The next frontier for offshore wind energy is moving further out to sea to avail of stronger and more consistent wind speeds. In these water depths, wind turbines are installed on floaters tethered to anchors in the seabed. Geotechnical design of anchors is inherently conservative, having been shaped by technical and economic considerations of oil and gas facilities. The offshore wind energy industry cannot afford to adopt such conservatism if floating wind is to become commercially viable. This project will, through numerical developments, geotechnical centrifuge modelling and field testing, develop the science that will lead to a reliability-based geotechnical design approach to make floating offshore wind energy economic and viable.Read moreRead less
