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.
Photonic crystals: The key to breaking the silicon-solar cell efficiency barrier. This project aims to investigate solar light harvesting using light trapping by photonic crystal on an amorphous-Silicon thin-film combining passivation technologies with light trapping.

The high cost of existing desalination technology has limited its wider application. There is an urgent need for alternatives which require less energy than current methods. The proposed electrosorption process utilising porous carbon electrodes has the advantage of very low energy demand. Electrosorption therefore has the opportunity to become an alternative desalination option for application in a national and global water desalination market. Advancement in water desalination technology has the potential for a profound social, economical and environmental impact. This vital research is aligned with the National Research Priority 1, An Environmentally Sustainable Australia; Priority Goal: Water, A critical resource.Read moreRead less
Nanosilver antimicrobial resistance in target pathogens. This project aims to elucidate the important phenomena of bacterial resistance to antimicrobial nanosilver, currently one of the most developed and commercialised products of nanotechnology.

This project aims to elucidate the important phenomena of bacterial resistance to antimicrobial nanosilver, currently one of the most developed and commercialised products of nanotechnology. The integrated research approach comprises of concurrent identification of the origins and routes of nanosilver toxicity in bacteria and the arising emergence and mechanisms of bacterial defence to the toxicity. The generated knowledge is to form a base template for novel nanosilver engineering with less tendency for resistance development and to facilitate tracking of resistance and its spread amongst microorganisms. The knowledge has far-reaching implications on the better governance of nanosilver use, including its disposal.Read moreRead less

The project aims to understand how the globally significant mixed-species growth of pathogens develop resistance to silver nanoparticle, currently one of the most important alternative antimicrobials to antibiotics. The integrated research is to elucidate, for the first time, the nanoparticle multi-targeting toxicity on mixed-species bacterial community and how, in turn, the bacteria activate their cell-to-cell signalling for a synergistic defence to adapt to the nanoparticle toxicity. The pioneering knowledge is the foundation for technologies targeting the interspecies metabolite cross-talking to overcome the resistance phenomena, ensuring a long-term efficacy of the alternative antimicrobial on the difficult-to-control pathogenic growth.Read moreRead less
