Breakthroughs in diamond nanothread technology
Through computer simulation, Dr Haifei Zhan and a team of researchers discovered that diamond nanothread can be made flexible, making it ideal for the creation of extremely strong three-dimensional nano-architectures. This finding enables scientists to apply both rigid and flexible properties so they can create both strong and versatile structures.
Optmising resources in the sugar milling industry
Professor Lin Ma received an ARC Linkage grant for her research project to develop methodologies for condition-based maintenance in the sugar milling industry. This work aims to help optimise industry resources and reduce the $350 million spent each year on maintenance in the sugar milling industry.
Research with real-world impact
Discipline leader Professor YuanTong Gu and Dr Noyel Thibbotuwawa are studying kangaroo shoulder cartilage as a proxy for worn out cartilage in human joints. The cartilage similarities enable the development of artificial implants which can relieve the pain of degraded shoulder joints and restore mobility.
Airports of the future
Professor Prasad Yarlagadda is leading our groundbreaking research into the future of air travel, which will help make airport experiences safer and faster. He has also been awarded a Medal of the Order of Australia for his services to engineering and the Indian community.
Turning up the heat on agricultural drying
Dr Azharul Karim received an Advance Queensland Fellowship for his research into an intelligent, microwave-assisted convective dryer for agricultural products. This drying technology significantly reduces drying time and energy usage in the fruit and vegetable industries.

"As I've gone through my degree more and more I've been able to have more and more of an influence, you know, on decisions made or even in the products that we designed here."
"I have found the masters experience academically challenging and relevant. This is my third degree and will be my second postgraduate qualification and QUT's admissions staff have been helpful in considering applications for credit in those areas where I already have qualifications. The class has a good mix of domestic and international students, which helps to create a more dynamic learning and cultural experience."
ARC Discovery Project
This project aims to develop a new multiscale model to investigate anisotropic and inhomogeneous mechanical properties of cartilage. It has been found that the mechanical properties of cartilage highly depend on its microstructures and components. The new model is proposed based on a new constitutive relation in the macroscale and a novel algorithm to obtain local stress distributions in the microscale as well as through rigorous experimental validations.
This model will be a powerful tool to understand cartilage mechanical properties. It will accelerate the design of mechanically viable artificial cartilage biomaterial, which will provide significant economic benefits and place Australia in the forefront of modelling and biomaterials.
ARC Discovery Project
This project aims to further understand the bactericidal properties of nano-pillared/textured surfaces, onto orthopaedic implants. It will do so by mimicking the nano-pillar structures derived from cicada wings by using Helium ion microscopy (HIM) and also Hydro Thermal techniques. The project also aims to study the physical mechanisms of the fracture of bacteria using numerical modelling.
This project will result in new generation implants with minimal bacterial infection that could result in cost savings to the Australian healthcare, improved quality of life in aged population, and may lead to the establishment of new implant industry sector in Australia.
ARC LIEF Grant
This project will establish a state of the art Xe-Plasma dual-beam facility providing characterisation and fabrication capabilities to Australia’s research community. The project will use two beams - one Xe, the other electrons - to mill the surface of bulk materials which are subsequently analysed by electron or ion beam techniques to determine atomic-scale microstructure(s) and compositions.
Anticipated outcomes are advanced materials engineering and new knowledge about ancient and future materials. This is expected to provide significant advances across a variety of fields including material science, engineering and geology and enhance trans-disciplinary collaborations.
ARC Discovery Project
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.
ARC Future Fellowship
This project aims to combine computational modelling, magnetic resonance imaging (MRI), mechanical measurement and pathological analysis to investigate carotid plaque progression, and quantify the critical blood flow and plaque stress/strain conditions under which plaque rupture is likely to occur.
MRI-based 3D computational models with multi-component plaque structures and their interaction with blood flow will be developed and solved numerically to identify suitable plaque rupture risk indicators. Mechanical properties of plaque components will be measured ex-vivo and fibre orientation-based constitutive rules will be developed. This project aims to lead to quantitative understandings of plaque progression and rupture.
Improving productivity and efficiency of Australian airports - A real time analytics and statistical approach
ARC Linkage Project
Aviation is a major economic driver both within Australia and overseas, but the aviation industry faces growing challenges from the increase in passengers and changing regulations. To meet these challenges, airports, airlines, government agencies and others need to maximise their efficiency and productivity; however, complex dependencies and differing operational objectives complicate this task.
This project aims to develop a real-time, whole-of-system operational performance framework that can help operators in finding and evaluating solutions to maximise throughput, reduce wait times and mitigate flow-on effects. Innovative new video analytic and Bayesian Network based tools are integrated to address the challenges of adaptability and uncertainty.
