ASLF lasers are portable and are transported between participating laboratories according to need and research priorities. Funds are sought to expand the ASLF by 3 laser systems and 2 research groups. The requested lasers provide mid-IR and deep UV wavelengths, spectral regions inaccessible with existing ASLF lasers. Access to these wavelengths is essential for Australian research to remain at the forefront of international physical chemistry research. ASLF laboratories support a wide range of chemical research including spectroscopy, environmental chemistry, astrochemistry, and exploration of nanostructured materials.Read moreRead less
Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silic ....Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silicon electrodes where irradiating with light causes an increase in conductivity at the illumination spot. The project will explore the variables that influence the spatial resolution and apply the ideas to making soft connects for nanoelectronics and making high density electrode arrays for electroanalysis.Read moreRead less

This project seeks to gain quantitative understanding of the role of electrostatics over chemical processes. Chemical transformations of organic compounds at interfaces underpin some of the most important processes, from the production of fine chemicals for pharmaceuticals to assisting bio-degradation of pollutants in clean technologies. Recent computational studies suggest that by applying oriented electric fields at interfaces, the rate and the selectivity of chemical processes can be altered at will. The project intends to test these theoretical findings. The knowledge generated by this research may translate into new technologies for the fine-chemical and biotechnology industries.Read moreRead less

The aim is to design nanosized TiO2 photocatalsysts with superior photoactivity using various synthesis paths. Nanosized TiO2 particles will be prepared using sol-gel, aerosol and plasma processing, their physical and chemical properties will be closely studied and their photocatalytic ability will be assessed. Such tailor-made photocatalysts have significant commercial potential value, as they would be highly suitable for the photooxidation of organic compounds and the photoreduction of metal ions in wastewaters. Findings from this work will pave the way for a "green" technology such as photocatalysis to become more efficient and hence a competitive alternative to conventional water treatment methods.Read moreRead less
Surface adsorption, repulsion and attraction: A new experimental approach to surface forces. The ability to understand and manipulate the stability of finely dispersed particles (colloids) in water is essential to modern living. It is necessary in processes as diverse as water purification, minerals separation, food and paper production. The behaviour of the colloidal system can often be understood in terms of the interaction between the dispersed particles. This project aims to improve our abil ....Surface adsorption, repulsion and attraction: A new experimental approach to surface forces. The ability to understand and manipulate the stability of finely dispersed particles (colloids) in water is essential to modern living. It is necessary in processes as diverse as water purification, minerals separation, food and paper production. The behaviour of the colloidal system can often be understood in terms of the interaction between the dispersed particles. This project aims to improve our ability to predict the nature of the interaction between dispersed particles, through an understanding of the events at a particle surface during a collision with another particle. This will enable us to better understand and control real colloidal systems.Read moreRead less

The management of greenhouse and other acid gas emissions is vital to a sustainable future of both the economy and the ecosystem. This project will develop novel nano-materials for gas separation by tethering organic functional groups to the surface of porous inorganic supports. These materials offer the promise of combining the high selectivity and high capacity of liquid phase absorption systems with the rapid transport rates of gas-solid adsorption systems. Success would open up several new possibilities for reengineering gas separation systems based on the use of these materials in solution, as solid phase adsorbents (pressure swing adsorption) and/or as permeselective gas membranes.Read moreRead less

In particular, new catalysts (i.e. agents that increase the speed and selectivity of chemical reactions) will be generated and the first steps towards process innovation will be taken, using high-throughput equipment unique in the Southern Hemisphere.

As a result the Australian chemicals industry will be more competitive.Read moreRead less

Molecules that can exist as mirror images, each with different, e.g., beneficial vs. toxic properties, underpin the pharmaceutical industry and increasingly new highly selective pesticides, and flavours/fragrances.

Molecules that can exist as mirror images, each with different, e.g., beneficial vs. toxic properties, underpin the pharmaceutical industry and increasingly new highly selective pesticides, and flavours/fragrances.
Current commercial pathways often make mixtures of the mirror images that then need to be separated laboriously. These routes are inefficient, creating waste and use resources poorly.
We aim to create solutions for these problems, using supported thin films of special, new types of salts that are liquid at room temperature, and which have other unusual chemical properties that make them ideally suited to enable efficient conversions.Read moreRead less
