Production and nano-characterisation of II-VI semiconductor quantum dots from plant cell cultures. Nanocrystallites with semiconductor properties have potential applications in medicine, microelectronics and waste treatment. Cheap, reliable methods for producing large quantities of monodisperse nanoparticles are required. Solution techniques have been used most commonly; however, production of stable, high-quality particles remains difficult.

Nanocrystallites with semiconductor properties have potential applications in medicine, microelectronics and waste treatment. Cheap, reliable methods for producing large quantities of monodisperse nanoparticles are required. Solution techniques have been used most commonly; however, production of stable, high-quality particles remains difficult. Biological synthesis using plant cell culture offers several important advantages. As peptide capping is incorporated into the biological assembly process, the nanoparticles are restricted in size, their stability is improved, and their surfaces are passivated. Application of plant cultures for nanocrystallite production is a novel approach with the potential to yield significant improvements in the quality of manufactured quantum dots.Read moreRead less
Photoelectrochemical control transport across a photoactive inorganic membrane fabricated by an in situ vapour phase hydrothermal method. Serious global fresh water shortage problems force us to recycle/reuse water. In Australia, this is an urgent issue due to our limited fresh water resources. Complete removal of biohazards (e.g., waterborne pathogens) from treated water is one of the most important aspects of safeguarding water recycling and has been the biggest obstacle for public acceptance. ....Photoelectrochemical control transport across a photoactive inorganic membrane fabricated by an in situ vapour phase hydrothermal method. Serious global fresh water shortage problems force us to recycle/reuse water. In Australia, this is an urgent issue due to our limited fresh water resources. Complete removal of biohazards (e.g., waterborne pathogens) from treated water is one of the most important aspects of safeguarding water recycling and has been the biggest obstacle for public acceptance. This project aims to tackle the issue by developing a highly efficient and effective new membrane technology that is capable of not just separating the biohazards from the source water but also in situ destroying them at the same time with low energy consumption and self cleaning features.Read moreRead less
