Advanced photoresists for 3D laser lithography

Some estimates state that 30% of all manufactured goods will be 3D printed in 2030. A particular type of 3D printing is 3D laser lithography, where micro- and nano-sized structures can be prepared. These structures find wide-ranging applications in meta-materials, functioning as invisibility cloaks or scaffolds for single (stem) cell interrogation. Today’s inks for 3D printing, however, are limited in their functionality, resolution and the obtainable material properties.This project will develop – in close collaboration with team members QUT's Soft …

Plasma printing – a new 3D manufacturing platform

Plasma printing technology is a rapidly emerging multidisciplinary research and development topic focused on the development of novel advanced technologies for additive manufacturing and 3D surface modification (3D printing) and roll-to-roll fabrication (2D printing) assisted by atmospheric-pressure low-temperature plasmas.

Spider silk: structure, mechanics and processing

Spider silks possess a range of qualities that are rarely found simultaneously in one material, and it is no surprise that an enormous effort has been made to replicate or learn from them.1,2 Toughness, extensibility and strength are only a few of the desirable traits that make spider silk of such interest. Silk is biodegradable and, unlike synthetic high-performance fibres such as Kevlar, it is extremely lightweight.3,4 A further advantage lies in its processing conditions and requirements. Whereas production of …

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 …

A golden approach to nanomedicine. Gold-polymer hybrid nanoparticles

Gold, a precious metal, is also highly valued for the production of highly functional nanoparticles.Gold nanoparticles interact with light and microwaves to generate heat and light, which can be used in nanomedicine for therapy or imaging. This project will look at developing polymer-gold hybrid nanoparticles to improve disease delivery and therapy. This project involves:polymer synthesismaterials formulation characterisation. …

Molecular Lego: building new materials piece-by-piece on surfaces

Single-atom thick materials represent the ultimate spatial limit for thin films.  At single-atom thickness, new physical properties can emerge along with new opportunities for reducing the size and operating power of devices made from these ultrathin materials.One of the main challenges in contemporary materials science lies in synthesising and characterising new single-atom thick materials.

Epitaxial growth of 2D heterostructures on SiC for electronics and gas sensing

Graphene has attracted a great deal of interest due to its remarkable electronic, optical and mechanical properties, however the absence of a bandgap limits its use in many applications. Future applications in nanoelectronics and gas sensing will depend critically on the development of novel approaches to introduce a bandgap while preserving carrier mobility, for example by creating heterostructures of graphene with other two dimensional (2D) materials with complementary properties.This project will explore the heteroepitaxial growth of new 2D materials to …

Computational design of 2D materials and surface functionalisation for catalytic application

Functionalised two-dimensional nanomaterials have attracted immense interest in materials design by combining the merits of large surface ratio and nano-size functionalisation, and have been able to meet the requirement of a variety of applications, including electronic devices, fuel cell, and catalytic application.Except for their tunable physical properties, of particular interest is their chemical reactivity and surface catalytic applications, because they can be more easily chemically modified by nano-size functionalisation. In this respect, numerous studies have been dedicated to exploring the …

Surgery with rockets

Self-propelled nano/microscale rockets have been developed that consume locally supplied chemical fuels to generate thrust, analogous to how large rocket engines ignite onboard propellants. Such rockets offer tremendous advantages as nano/microdevices. They can be designed for low or high velocities (up to 1000 body lengths/sec), can tow large loads, have remarkable design flexibility, and allow surface functionalisation with nanomaterials and biomolecules.1,2Unlike their macroscale counterparts, these rockets have the advantage of harvesting their chemical fuel directly from their surrounding environment. In …

Understanding and exploiting the phenomenal properties of collagen

Collagen is the most abundant protein in the human body and, as one of its principal building blocks, plays a dominant role in the function of many tissues. As such, the structure-property-function relationships in collagen are central to understanding health and disease, and developing materials-based strategies for regenerative medicine. A better understanding of these relationships further provides a biomimetic target for high-performance, multifunctional fibre-based materials in applications outside of biomedicine. The defining feature of collagen is an elegant structural motif …
