Investigation of roughness and wettability model of nanostructured surfaces for biomedical devices

All nanostructured surfaces have unique surface roughness which mathematically describes by the surface architecture or the geometry. Moreover, the nanostructured surfaces may have variable water contact angle values due to the combination of surface roughness and surface composition. The correlation of surface roughness and wettability of nanostructured surfaces to the antibacterial activity becomes significant in designing a numerical model for biomedical devices.

Surface engineering of Ga2O3 for nanoelectronic devices

Ga2O3 is an emerging wide-bandgap semiconducting material that has received enormous attention in recent years due to its potential application in power devices, UV detectors and military applications that are unattainable by conventional semiconductors such as silicon.The operation and performance of these type of electronic devices rely critically on the surface quality and properties of the semiconducting materials. However, the surface atomic structures and electronic structures of Ga2O3 single crystals are not yet fully understood.The principal aim of this project …

Energy Storage Supercapacitors

Supercapacitors, also called electrochemical capacitors, are a type of energy storage system that are complimentary to batteries; enabling fast energy release (high power density) and over ten thousands cycles.Our research is trying to enhance the energy density of the supercapacitors by designing new electrode materials with tailored nanostructure and composition. This is achieved by taking advantage of the Faradaic charge transfer of transition metal compound or composites or by anionic chemistry in solution.

Diamond optoelectronic devices: switching diamond by light

Beyond its allure as a precious gemstone, diamond is regarded as an excellent material for electronic and optical applications, owing to a range of extraordinary material properties. Although diamond is highly insulating in its bulk, its surface, once terminated by hydrogen, can develop an intriguing p-type surface conductivity which can be rationally tailored by interfacing diamond with other materials. The two-dimensional hole gas (2DHG) on diamond surface, which supports the surface conductivity, also exhibits many interesting quantum properties that can …

Complex networks as computational devices

Inside each living cell is a tiny universe unto itself: vast interconnected communication networks of signaling molecules (mostly proteins, including enzymes, scaffolds and small molecules ('second messengers'), that dynamically assemble and disassemble in order to interpret stimuli and signals generated both outside and within the cell.We are now beginning to decipher the extraordinary mathematical properties of cellular signalling networks. The remarkable characteristics of these complex networks enable them to represent a kind of 'brain for the cell - allowing the …

One coating to rule them all: preventing infections to medical devices

Infections to medical devices are still a major complication. This project investigates a new antimicrobial coating that could be readily applied on all surfaces to prevent bacterial attachment and growth. The project is in collaborations with leading device R&D companies and manufacturers both in Australia and overseas and thus would give students opportunities for industry exposure.

Micro-scale manufacturing of medical devices

Biofabrication research is enabling a transition in medical manufacturing from generic, mass-produced implants to patient-specific solutions with customised external shape and internal porous architecture that mimic natural tissues to improve the healing process.Melt electro-writing is a rapidly emerging manufacturing technique allowing the production of incredibly small polymer and composite devices. Medical applications are of particular importance using this technique as fine porous microstructures can be manufactured that mimic those of natural tissues, improving tissue integration and biological response.A significant problem …

3D printing of urethral dilators

The urethra is a tube that drains urine from the bladder and can sometimes narrow due to injury and infection, known as urethral strictures. Passing increasing sized metal urethral sound dilators through male urethral strictures was the classical treatment for strictures. Although success rates are around 65%, these procedures are surgeon dependant and carry the risk of inadverted trauma to the delicate urethral membrane.Most surgeons now use a Seldinger technique, with the Cook S-curve© dilators. These offer a safe, effective …
