Rotational Degrees Of Freedom In Modelling Of Materials With Intrinsic Length Scale. In many applications, from nanotechnology to construction and mining, the modelled objects are not large enough as compared to the material constituents for classical continuum modelling to be adequate, but yet encompass too many elements for comfortable particle-type computer simulation. Generalised continua would offer a viable option if a rational method of their construction for each intrinsic material struc ....Rotational Degrees Of Freedom In Modelling Of Materials With Intrinsic Length Scale. In many applications, from nanotechnology to construction and mining, the modelled objects are not large enough as compared to the material constituents for classical continuum modelling to be adequate, but yet encompass too many elements for comfortable particle-type computer simulation. Generalised continua would offer a viable option if a rational method of their construction for each intrinsic material structure were at hand. The project aims at developing the necessary homogenisation procedure and constructing generalised (Cosserat) continuum models of deformation, wave propagation and impact fracture in particulate and layered materials such as multi-wall nanotubes, fullerenes, particulate composites and layered rock masses.Read moreRead less

Summary
Nanoengineering of low-CO2 geopolymer cements. With increasing pressure for Australia to use environmentally-conscious building materials, geopolymer concrete is an important emerging alternative to traditional concretes. This project will enhance use of this new material by discovering how to control performance and durability through nanoscale experiments and atom-based simulations.
Aerodynamic enhancement of the capture of fine particle emissions and gaseous pollutants by sorbents. Fine particulate emissions alone, and just within Australia's four largest cities, are estimated to be responsible for some 1600 deaths annually, and are a leading cause of asthma and other lung disease. Hence the economic and social benefits of greatly reducing fine particulate emissions is enormous. Similar benefits can be expected to arise from the enhanced capture of SOx, NOx and heavy metal ....Aerodynamic enhancement of the capture of fine particle emissions and gaseous pollutants by sorbents. Fine particulate emissions alone, and just within Australia's four largest cities, are estimated to be responsible for some 1600 deaths annually, and are a leading cause of asthma and other lung disease. Hence the economic and social benefits of greatly reducing fine particulate emissions is enormous. Similar benefits can be expected to arise from the enhanced capture of SOx, NOx and heavy metals. Many of these pollutants also contribute to the greenhouse effect, so the international exploitation of the technology will also help to mitigate climate change. Should suitable sorbents be developed for CO2 capture, the technology will also enhance carbon capture and storage.Read moreRead less

Interface Engineering of Multilayer Nanostructures. Nanostructured multilayers can outperform coatings of their constituent layers in both hardness and strength. It is believed that the nature of interfaces in these materials is critical since they mediate dislocation motion and crack propagation. This project will use advanced synthesis, microanalysis and theoretical methods to investigate multilayer coatings with sharp, diffuse and rough interfaces in order to reveal their failure mechanisms u ....Interface Engineering of Multilayer Nanostructures. Nanostructured multilayers can outperform coatings of their constituent layers in both hardness and strength. It is believed that the nature of interfaces in these materials is critical since they mediate dislocation motion and crack propagation. This project will use advanced synthesis, microanalysis and theoretical methods to investigate multilayer coatings with sharp, diffuse and rough interfaces in order to reveal their failure mechanisms under stress. This will enable us to understand the principles required to design the strongest structures and facilitate the selection of materials and deposition parameters in order to produce coatings optimised for a range of demanding applications.Read moreRead less
