Response of Proteins to External Non-Ionising Radiation: an Experimental and Computer Modelling Investigation. The expanding use of digital technologies such as mobile phones has led to major health concerns about the effects of non-ionising pulsed radiation exposure which has been shown to produce instantaneous temperature rises undetectable by normal thermometry. The health implications of exposure are not understandable without establishing molecular mechanisms by which pulsed microwaves can ....Response of Proteins to External Non-Ionising Radiation: an Experimental and Computer Modelling Investigation. The expanding use of digital technologies such as mobile phones has led to major health concerns about the effects of non-ionising pulsed radiation exposure which has been shown to produce instantaneous temperature rises undetectable by normal thermometry. The health implications of exposure are not understandable without establishing molecular mechanisms by which pulsed microwaves can cause biological effects. We aim to establish methods for studying the molecular mechanisms of protein structural and energetic changes occurring due to non-ionising radiation. The results will help our industry partner to design specific drugs as well as formulate a scientifically based standard for microwave utilisation.Read moreRead less

Study of molecular interactions between wood pitch fixatives and components of wood pitch. Wood resins, released in pulping, agglomerate in the papermaking process to cause pitch deposits. These deposits adversely affect paper machine efficiency and product quality and limit further recycling of process water. This project aims to investigate the interactions between the components of the wood resins and different fixatives using capillary electrophoresis and other techniques. This knowledge w ....Study of molecular interactions between wood pitch fixatives and components of wood pitch. Wood resins, released in pulping, agglomerate in the papermaking process to cause pitch deposits. These deposits adversely affect paper machine efficiency and product quality and limit further recycling of process water. This project aims to investigate the interactions between the components of the wood resins and different fixatives using capillary electrophoresis and other techniques. This knowledge will provide a better understanding of the role of the physical and chemical properties of the fixatives in fixing the different compounds in wood resins. Molecular modelling will be used to design new fixatives that will be selective to a mixture of wood resins.

Reduced water usage in the Australian pulp and paper industry through novel process chemistry. Norske Skog Paper Mill operates two paper mills on major rivers in Australia. For these mills to reduce water consumption greater recycling of the process water is needed which results in a build-up of detrimental substances that will affect paper machine performance and efficiency. The knowledge gained from this project will help the paper mills to find strategies to control the build-up of the detr ....Reduced water usage in the Australian pulp and paper industry through novel process chemistry.

The Development of Computer-Aided Molecular Modelling and Drug Design Techniques for Flexible Enzyme Targets - New Anti-HIV Agents. The dynamic motion of proteins upon binding of small molecules is crucial in many cases for the function of the protein or for the function of drugs acting upon the protein. Current methods in computer-aided design of small molecules binding to proteins do not take this protein flexibility fully into account. This project intends to develop molecular dynamics simula ....The Development of Computer-Aided Molecular Modelling and Drug Design Techniques for Flexible Enzyme Targets - New Anti-HIV Agents. The dynamic motion of proteins upon binding of small molecules is crucial in many cases for the function of the protein or for the function of drugs acting upon the protein. Current methods in computer-aided design of small molecules binding to proteins do not take this protein flexibility fully into account. This project intends to develop molecular dynamics simulation techniques for this purpose, initially using the HIV reverse transcriptase enzyme as the target protein. The methods developed will, however, be universally applicable. The project further aims to design, synthesise and test novel medicinal agents specifically against drug resistance in HIV.Read moreRead less
Colloid interactions and extraction in sustainable, water efficient paper manufacture. This project will investigate the causes of wood extractive deposits on modern high-speed printing surfaces. The project will also develop alternatives to prevent their deposition in an environmentally sustainable manner, and to remove them from the paper making process allowing their utilisation as valuable natural products.

Nature makes use of a range of fascinating surface properties, such as the leaves of the Lotus plant which stay clean even in dirty environments. In this project we will explore the molecular properties of novel polymer coated surfaces that-similar to some natural surfaces-can adapt to changing environmental stimuli and be resistant to contamination. Specifically, we aim to develop self-cleaning polymer coatings which can reversibly switch from wettable to non-wettable with changing temperature and humidity. These self-cleaning polymer surfaces with environmentally responsive properties will add value to pre-painted steel products and other coatings.Read moreRead less

Controlling morphology and self-organization at a molecular level is key to advancing the performance of optoelectronic devices such as organic light-emitting diodes and organic photovoltaic cells. Current device development relies on a costly and inefficient empirical design cycle (material synthesis followed by device fabrication and testing). In addition, the active layers often involve multiple components and their nano-scale morphology is difficult to probe experimentally. Recently developed molecular simulation techniques can provide unique insight into atomic-level structural details that determine device efficiency. The project will determine if such simulations are sufficiently accurate to be industrially useful.Read moreRead less
