This project aims to develop a novel hierarchical multi-scale modelling framework to understand factors that influence the mechanical deformation behaviour of the extracellular matrix (ECM) such as cartilage, whose mechanical performance is critical to human wellbeing. Modelling ECM presents significant challenges due to the need to incorporate effects at scales from atomic interactions up to the fibre network in a continuum model. The proposed framework follows ECM's natural hierarchical structure and integrates efficient models for each key structural scale based on rigorous experimental validations. It is expected to provide a powerful tool for designing successful artificial ECM materials and understanding the mechanisms of the ECM degradation.Read moreRead less

Aims: The project aims to comprehensively study heat and mass coupling in liquid alloys by describing it mathematically, measuring it experimentally and calculating it by simulation. Significance: When a liquid alloy exists at different temperatures, the coupling of heat and mass flows causes rapid segregation of its components. This is a major complication in controlling solidification from liquid alloys in manufacturing and in the design of liquid alloy coolants for efficient heat transfer. It has never been addressed. Expected outcomes: This research is expected to be the pioneering foundation of the area. Benefits: It is anticipated that the research would provide the means to properly control the engineering use of liquid alloys. Read moreRead less

The cryo-FIBSEM will be the first instrument of this type in Australia able to operate in a low temperature cryogenic mode. This will enable the imaging of vitrified biological materials in a near native state and of non-biological material to allow imaging of, for example, fluids, emulsions, gels and interfaces between biological and non-biological materials. Synergistic workflows incorporating unique high-end microscopes will enable the study of complex biological structures in their native context and atomic scale imaging of beam sensitive materials.Read moreRead less
