Interactions between nanoparticles and bacteria. This project aims to understand how nanoparticles interfere with bacterial metabolism, and how these interactions lead to cell death, lysis and dispersal from biofilms. Intensive use of nanomaterials results in their continuously releases into the environment. While various nanoparticles have inhibitory and even toxic effects on microorganisms in ecosystems, the underlying mechanisms are not understood. This project will investigate model organism ....Interactions between nanoparticles and bacteria. This project aims to understand how nanoparticles interfere with bacterial metabolism, and how these interactions lead to cell death, lysis and dispersal from biofilms. Intensive use of nanomaterials results in their continuously releases into the environment. While various nanoparticles have inhibitory and even toxic effects on microorganisms in ecosystems, the underlying mechanisms are not understood. This project will investigate model organisms’ responses to nanoparticles at the cellular, enzymatic and gene expression levels. The findings are expected to help assess the immediate and long-term effect of nanoparticles on ecosystem health, for improved environmental management.Read moreRead less

Effective control of the quality of water supply is paramount for public health. This project aims to develop a novel photoelectrocatalysis (PEC) based bactericidal technology capable of instant inactivation and rapid decomposition of waterborne pathogens in recycled water. The PEC processes at the illuminated semiconductor photoanodes with ultraviolet (UV) and visible light activities will be innovatively utilised with the aim of in-situ generation of stable di-halide radical anions, reactive oxygen species and photoholes as effectual bactericides to achieve instant inactivation and rapid decomposition of waterborne pathogens. The success of the project is expected to provide Australian water industry with enabling technology to safeguard recycled water usage.Read moreRead less
Capturing full-spectrum of solar energy using TiO2 ordered suprastructures. The project aims to develop a titanium dioxide (TiO2) semiconductor that can use full-spectrum solar energy. Solar-driven photocatalytic processes have important applications in water decontamination and energy production. Their effectiveness is dictated by the semiconductor’s absorbance and conversion of photoenergy to chemical energy.

The project aims to develop a titanium dioxide (TiO2) semiconductor that can use full-spectrum solar energy. Solar-driven photocatalytic processes have important applications in water decontamination and energy production. Their effectiveness is dictated by the semiconductor’s absorbance and conversion of photoenergy to chemical energy. Being inexpensive, chemically and mechanically robust, TiO2 is the most promising material for the semiconductor. However, unmodified TiO2 only absorbs ultraviolet light (5 per cent of solar energy). With current progress made in visible absorbance, this project aims to significantly improve TiO2’s absorbance in near infrared by doping with upconversion lanthanides and rendering colloidal crystal suprastructures that can trap light.Read moreRead less
