Discovery and design of novel catalysts from computational chemistry

The discovery and design of novel materials as efficient catalysts are critical for the development of innovative clean energy and environmental technology. For example, hydrogen production involves hydrogen evolution and oxygen evolution reactions - oxygen reduction/evolution reactions are important in fuel cell and air battery technology, carbon dioxide reduction is related to the mitigation of carbon emission, and nitrogen fixation is linked to the fertiliser production process.In principle, the catalytic properties of a material are completely determined by its electronic …

Use of depth sensing technology in radiotherapy and medical imaging

Consumer-grade depth sensing technology has in recent years become widely available. A number of vendors have developed similar technologies.Some examples of these technologies include:Intel’s RealSense™Asus Xtion depth sensorQualcomm Spectra ISP platform, now in its second generation.The systems make use of camera technology that measures the distance to a surface. Rapid image acquisition can then enable real time motion detection of location of the surface. The infra-red transmitter and sensor use a time-of-flight method to construct a depth map, in millimetres, …

Development of 3D tumour models for radiobiology applications

There is increasing interest in developing 3D tumour models for use in cancer research. The models have been used to investigate and test novel therapies in a model that is closer to the in-vivo tumour micro-environment. So far there has been little investigation of their use for therapeutic interventions that include ionising radiation. This research will investigate how they may be used for studying the fundamental radiobiology of radiotherapy treatments for cancer.

Topological control over cell behaviour for robust additive tissue biomanufacturing

Hospital departments are adopting medical imaging, modelling, and 3D printing to automate personalised implant manufacture and avoid malpractice related to surgical handcrafting. Although several 3D printed implants are approved for medical use, their therapeutic value remains limited as acellular devices with coarse resolution. The ability to print scaffold implants with cell microenvironment precision has been achieved using melt electrowriting (MEW), an emerging technique frequently applied to produce cell culture scaffolds.In contemporary MEW studies, the effect of materials or pore sizes …

Estimation and control of networked cyberphysical systems

Cyberphysical systems (CPS) integrate sensors, communication networks, controllers, dynamic processes and actuators. CPS play an increasingly important role in modern society, in areas such as:energytransportationmanufacturinghealthcare.Due to the interplay between control systems, communications and computations, the design of CPS requires novel approaches, which bridge disciplinary boundaries.We're interested in developing engineering science and methods for the analysis and design of CPS operating in closed loop. Our research brings together elements of control systems engineering, as well as telecommunications and reinforcement learning.The current …

The use of PET-MRI in radiotherapy treatment planning

PET/CT is frequently used to assist in the planning of radiotherapy treatments. The PET information can help with determining the extent and function of the tumour as well as possible involvement of lymph nodes. This could result in improved targeting of the radiation to the disease.PET/MRI offers a number of advantages over PET/CT for head and neck cancer radiotherapy treatment planning. The MRI offers superior soft tissue contrast and no ionising radiation dose compared to the current standard of care, …

Fighting slime with nitroxides and polymers

Biofilms, more commonly recognised as slime, are complex communities of microorganisms, which provide these creatures with a niche where they are able to flourish in conditions where they might not normally survive.Because of this enhanced survivability, bacterial biofilms show enhanced resistance to disinfectant and antibiotic treatment, and are the cause of nearly three quarters of hospital-acquired infections. Nitroxides, molecules that possess a stabilised free radical, are able to disperse these biofilms and make them susceptible to treatment.Our research group is …

Hearing colour and seeing sound – switchable optoacoustic imaging agents

Optoacoustic imaging is a new medical imaging technique. It utilises laser light to excite an imaging agent, which in turn converts this light energy into heat. This heat is dissipated as a sound wave, which can be detected with an ultrasound receiver. This technique aims to overcome the minimal penetration depth of fluorescence imaging, and the lack of molecular specificity of ultrasound.In this project we are aiming to develop and synthesize intelligent imaging agents for optoacoustics, which are able to …

Highly fluorescent and brighter emitters for next generation flexible OLEDs and displays

Display devices are composed of an array of organic light emitting diodes (OLED) in the form of pixels (red, blue, green). Such devices are present in various electronic appliances, including:mobile phonestabletstelevisionssmart packaging productswearable productsautomobile dashing boards.Currently, inorganic light emitting diodes (LEDs) control the display market, but this technology has some limitations such as:high fabrication costlarger area processinglimited to rigid products.The next generation of devices are expected to be flexible and stretchable so they can be used for future rollable televisions …
