The information from Human Genome Project is being used to generate molecules with a variety of therapeutic and diagnostic applications. The capability to design, synthesise and manipulate functional molecules that mimic biological processes will underpin many emerging applications. In this project, macrocyclic metal complexes that catalyse the cleavage of phosphate ester bonds in biological molecules will be developed. Active complexes will be incorporated into nanosized peptide nucleic acid (PNA) - metal complex hybrids and applied as artificial enzymes in the sequence specific cleavage of RNA and DNA. Novel applications of these ?artificial enzymes? in biotechnology are anticipated.Read moreRead less

Summary
National magnetochemical facility. New magnetic materials of the molecular or biological types are quite different to traditional metal oxide magnets widely used, for example, in recording devices. They are very important from the perspective of understanding fundamental properties at low temperatures, in high magnetic fields, or when irradiated by light, but they are also showing promise in a range of applications, such as memory devices and smart cards and in the new area of spintronics and m ....National magnetochemical facility. New magnetic materials of the molecular or biological types are quite different to traditional metal oxide magnets widely used, for example, in recording devices. They are very important from the perspective of understanding fundamental properties at low temperatures, in high magnetic fields, or when irradiated by light, but they are also showing promise in a range of applications, such as memory devices and smart cards and in the new area of spintronics and molecular computers. The magnetochemical projects described here, that require the new equipment being sought, are fundamental in nature but will provide the underpinning of future nanomagnetic materials.Read moreRead less

Hydrogen fuel production from electricity and water sources, such as sea water, represents the ultimate goal for the research described here. This is part of an overall scheme, called "Artificial Photosynthesis", to generate clean renewable energy. The present project is an important step in this ambitious program and directly addresses a key hurdle which must be overcome to make artificial photosynthesis feasible. This hurdle is the efficient electrical conversion of water into hydrogen and oxygen, a two part process of which the latter is the most chemically difficult. The project aims to 'steal nature's secrets', by deciphering and then technologically mimicking the highly efficient means by which plants carry out these processes.Read moreRead less
Bio-inspired Catalysts for Water Oxidation. Successful completion of the project will result in the development of devices that utilise redox active manganese clusters to catalyse the oxidation of water. This achievement would place us at the forefront of international efforts to develop devices that can split water into hydrogen and oxygen, an endeavour which has the potential to solve pressing energy demands. As an added benefit, these devices can be adapted for the purposes of carrying out th ....Bio-inspired Catalysts for Water Oxidation.

This achievement would place us at the forefront of international efforts to develop devices that can split water into hydrogen and oxygen, an endeavour which has the potential to solve pressing energy demands. As an added benefit, these devices can be adapted for the purposes of carrying out the catalytic oxidation of organic substrates, for which a variety of industrial and environmental applications can be envisaged.

Redox initiated chemistry of hydrogenase H-cluster model compounds: Biologically inspired hydrogen activation catalysts? High efficiency, low temperature, cheap hydrogen activation catalysts suitable for fuel cell applications would provide the basis for the development of environmentally benign technologies suitable for transportation and some power applications.

High efficiency, low temperature, cheap hydrogen activation catalysts suitable for fuel cell applications would provide the basis for the development of environmentally benign technologies suitable for transportation and some power applications. Hydrogenase enzymes are high efficiency, low temperature, hydrogen activation catalysts and the active site of the all-iron version of the enzyme has recently been revealed to be a remarkable, weakly protein bound, iron-sulfur-carbonyl-cyanide complex. Research into the reactions of redox activated abiological model compounds will provide insights into the molecular basis of the enzymatic reaction, potentially leading to the discovery of highly efficient, biologically inspired hydrogen activation catalysts.Read moreRead less

One coordinate carbon and boron: Universal progenitor ligands. Compounds with bonds between metals and carbon (organometallic chemistry) underpin innumerable important industrial processes from fine chemicals to bulk agrochemical and polymer synthesis. Yet the simplest example, a single atom of carbon bound to a metal has only recently been discovered and is poorly understood. Australia's fledgling boron fine chemicals industry similarly benefits from metal-based processes. However, compounds wi ....One coordinate carbon and boron: Universal progenitor ligands. Compounds with bonds between metals and carbon (organometallic chemistry) underpin innumerable important industrial processes from fine chemicals to bulk agrochemical and polymer synthesis. Yet the simplest example, a single atom of carbon bound to a metal has only recently been discovered and is poorly understood. Australia's fledgling boron fine chemicals industry similarly benefits from metal-based processes. However, compounds with a single boron atom bound to a metal remain unknown. This proposal addresses metal-carbon and metal-boron chemistry from the most basic perspective, that of a single atom of boron or carbon, including the development of novel synthetic approaches and skills for the characterisation of such curious species.Read moreRead less
