Nanochemistry Research Institute - Research. The study of nanochemistry demands a multidisciplinary approach, and projects can involve bulk synthetic techniques, advanced microscopy techniques, computational molecular modelling and/or organic synthesis of new molecules designed to control nanoparticle formation, or spontaneously assemble into complex architectures. The broad range of research in the Institute is captured in the Program Areas. These are the particular areas of strength that the Institute can bring to bear on any problem. A particular project is likely to span two or more of these areas, and current activities in each of the areas are summarised on the appropriate pages. Bio- nano. Enhanced cell growth induced by the controlled released vascular endothelia growth factors (VEGF) from polymer microspheres. Calcification studies of implantable polymer hydrogels. Adequate porous structure is critical for tissue and cells to grow in a polymer scaffold. Biocompatibility studies aim to understand the cell and protein responses to the surface of polymer implants. Bio- nano represents one of the major program areas at NRI, and involves many researchers within the institute, synergising their expertise in the fields of computer simulation, crystallisation, solid state chemistry, synthetic chemistry (macromolecules and polymers) and nano- characterisation. The research activities are particularly focused on biomaterials (including implantable materials, tissue scaffolding materials and biocompatibility studies), controlled drug delivery, computer simulation of biochips and molecular dynamics of biological molecules, ferrihydrite as a nano- material, biomineralisation, biosensors and the property control of the biomolecule lactose. Current Activities. Listed below are a few research projects that are currently underway. More details can be obtained from the indicated web links.

Prime Minister Tony Abbott and Federal Member for Curtin and Foreign Minister Julie Bishop yesterday met with researchers and staff at the Telethon Kids Institute to see firsthand the work being done to improve the health and. Property Development and valuation is suited to people who are interested in residential and commercial property, enjoy networking and want to work in a varied, dynamic and international profession. Ultimately, its aim is to control the precipitation process to the desired outcome (control of particle size and/or shape, mitigation of scale etc.). It remains one of our primary areas of expertise that is utilised in many of the NRI projects. Current Activities. The projects cover a broad spectrum of fields; ranging from mineral systems of iron, silica, barium sulfate and calcium carbonate to organic molecules such as lactose. The involvement of the group within the Parker CRC for Integrated Hydrometallurgy Solutions means that much work is relevant to hydrometallurgical processes. There is also a substantial crossover with the macrocyclic organic area that is used to great effect to develop new additives for various systems. Additionally, there are also two ARC funded projects in this area. Below are further details. Iron and silica precipitation. Investigation of the effect of additives on silica precipitation in Bayer liquors. Franca Jones. 2. Bio- inspired Crystal Growth. Fundamentals of crystallisation. Nanoparticle formation and molecular recognition. One- on- one industry projects. In all of these projects there is an emphasis on understanding the fundamental mechanisms of crystallization and using state of the art techniques such as AFM and computer modelling. Funding. Research in this area began with funding from CRCs and industry, and now. ARC funding. Functional Molecules. The Functional Molecules program area is focused on the design, synthesis and study of molecules with targeted functionality for specific applications. Projects within the area involve both fundamental and applied research. The Functional Molecules group also provides the NRI with the capability to synthesize new and known molecules for other research programs within the Insitute. Current Activities. The lead researchers of the Functional Molecules program area are AProf Mark Ogden, AProf Mauro Mocerino and Max Massi. Listed below are a few current research projects. More details can be obtained from the links to the individual researchers. Current Activities. A range of research activities are currently underway, many of which overlap with the crystallization and solid state chemistry programs. Control and inhibition of scale formation.

Barite. a: A theoretical AFM style surface plot. A representation of the molecular surface that has been colour coded with the calculated electrostatic potential. When working at the nanoscale, interpreting experimental information can be a complex process. The aim of the theoretical and computational nanochemistry program is to provide detailed understanding of the processes occuring at the atomic and electronic level in order to both rationalise experiments and to make predictions. The theoretical and computational group with in the Nanochemistry Research Institute is involved in the development of new methodologies and software, as well as the application of the techniques to current scientific problems. Current Activities. The projects being investigated span many areas of science from nanochemistry, through nanotechnology to materials science.

Our research involves the use of atomistic simulation based on either force- field method or quantum mechanics. Both lattice dynamics and molecular dynamics are utilized according to the nature of the problem. In addition to using standard implementations, we are also involved in the development of new methods and their implementation into software. Force- field methods are developed and distributed through the program GULP which is freely available to academics around the world. Linear- scaling density functional theory for periodic systems is also being developed through the program SIESTA in collaboration with other members of the development team. Funding. Our research is supported by funding from the Australian Research Council under the Discovery, Linkage and LIEF programs. Computing resources are provided through the Western Australian supercomputer centre, i. VEC, and the National Computational Infrastructure (NCI) program.
