Summary
Interaction between silver ions, silver nanoparticles and reactive oxygen species: implication to toxicity. The project investigates the ability of various different (supported and stabilised) types of nanosized silver particles (SNPs) to oxidatively degrade selected contaminants and or kill microorganism. The project also aims to determine the effect of solution condition (for example pH) and light on SNP longevity and hence their oxidative capacity.
SYNTHESIS OF A NANO-STRUCTURED TITANIA SURFACE AND ITS APPLICATION IN PHOTOCATALYTIC OXIDATION FOR WATER TREATMENT. Australia is facing severe freshwater crisis. Although there is an increasing public awareness of saving and using water efficiently, re-using water/wastewater has been neglected. In Australia, 97% of city runoff and 86% of effluent water is unproductive. How to recycle and re-use them becomes an urgent issue.

Australia is facing severe freshwater crisis. Although there is an increasing public awareness of saving and using water efficiently, re-using water/wastewater has been neglected. In Australia, 97% of city runoff and 86% of effluent water is unproductive. How to recycle and re-use them becomes an urgent issue. This project attempts to develop novel titania based photocatalysts to convert organic contaminated water into reusable/potable freshwater. The project's innovation lies in the synthesis of highly reactive nano-structured titania surfaces in fixed form to solve downstream separation problem. Successful development of such photocatalysts will show significant environmental and socio-economic benefits to Australia.Read moreRead less

Bacterial cell behaviour in micro/nano-confined environments. The project aims to progress the understanding of the mechanisms of marine bacteria biofilm formation and surface-modulated metabolic response. We will adjust the surface characteristics of photopolymers (as ?model? surfaces) and probe the bacterial response to surfaces, passively with micro/nano-fabricated structures and Atomic Force Microscopy; and actively with optical manipulation of single cells.

We will adjust the surface characteristics of photopolymers (as ?model? surfaces) and probe the bacterial response to surfaces, passively with micro/nano-fabricated structures and Atomic Force Microscopy; and actively with optical manipulation of single cells. The results will contribute to the fundamental knowledge regarding central biological phenomena -down to single-cell processes- as well as on applied knowledge regarding the manufacturing of antimicrobial surfaces that mimic natural bactericide processes, with larger implications on biomedical practice, and environmental, civil, mining and manufacturing industrial applications.Read moreRead less
Advanced lanthanide-doped nanomaterials for new-generation security inks. Current security labelling technologies using pattern coding (“barcoding”) and/or UV-excited phosphorescent inks are relatively easily counterfeited. The project aims to identify optimal design, fabrication and surface treatment of infrared-excited lanthanide nanoparticles for use as pigments in UV-curable polymer inks.

Current security labelling technologies using pattern coding (“barcoding”) and/or UV-excited phosphorescent inks are relatively easily counterfeited. The project aims to identify optimal design, fabrication and surface treatment of infrared-excited lanthanide nanoparticles for use as pigments in UV-curable polymer inks. This is expected to result in a new-generation of jet-printable security inks with ultimate capability for multidimensional coding (using multiple luminescence wavelengths and lifetimes) and robust readability. Expected outcomes are world leadership in codable inks for secure labelling against counterfeiting, greatly enhancing both global ink-product sales and the value of Australian exports subject to product substitution.Read moreRead less

Nanostructured multilayers can outperform coatings of their constituent layers in both hardness and strength. It is believed that the nature of interfaces in these materials is critical since they mediate dislocation motion and crack propagation. This project will use advanced synthesis, microanalysis and theoretical methods to investigate multilayer coatings with sharp, diffuse and rough interfaces in order to reveal their failure mechanisms under stress. This will enable us to understand the principles required to design the strongest structures and facilitate the selection of materials and deposition parameters in order to produce coatings optimised for a range of demanding applications.Read moreRead less

The conventional process involves the manufacture of copper-plated, chrome-coated cylinders into which the desired image is engraved. The cylinders have high manufacturing and operating costs. The chemicals used in the process are highly toxic and therefore pose major threats to humans and environment. This proposal outlines the first attempts to develop a new and innovative hybrid organic-inorganic nanocomposite material to replace the copper plating and chrome coating. The success of the project will offer high quality, affordable and environmentally friendly printing service to both local and international clientele.
