Summary
800 MHz NMR spectrometer for biomolecular structure-function analysis. An understanding of how organisms function at the molecular level is central to developing the ability to fight many diseases in a rational way. This equipment will provide the capability for many different laboratories around NSW and the ACT to advance our knowledge at this fundamental level, primarily by examining the structures and functions of biomolecules such as proteins.

Realistic models of permeation in ion channels. Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes.

Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes. Recent determination of the crystal structure of channel proteins has enabled construction of models that can relate channel function to its structure--necessary for understanding their operation and seeking cures for diseases caused by their malfunction. This project aims to develop accurate ion-protein-water interactions for permeation models based on stochastic and molecular dynamics simulations using both classical and quantum mechanical methods.Read moreRead less
Intermolecular interactions revisited-Flaws in the fabric and applications to lower-dimensional structures. This project aims to capitalise on recent developments, that have shown that previously accepted theories are deeply flawed, in various applications in fundamental physics and in unsolved problems in biology that involve electromagnetic fields.

by electromagnetic fluctuation forces, and real photon exchange, between molecules will be investigated.

This project aims to capitalise on recent developments, that have shown that previously accepted theories are deeply flawed, in various applications in fundamental physics and in unsolved problems in biology that involve electromagnetic fields. Interactions driven
by electromagnetic fluctuation forces, and real photon exchange, between molecules will be investigated. The project will investigate how dispersion interactions change in mesoscopic pores, in electrolytes, and at finite temperatures. Applications involve
catalysis, molecular formation, and quantum logic. The project also aims to develop a unified theory for energy and charge transfer, relevant for photosynthesis and the way biological molecules transfer information.Read moreRead less
Disorder as a novel determinant of photosynthetic structure and function: an experimental study. Australia enjoys a world reputation in photosynthesis research, typified by hosting the 2001 International Photosynthesis Congress. It also has a claim to fame for theoretical work in non-equilibrium thermodynamics concerning production of disorder or entropy, yielding new insights into planetary climates.

Australia enjoys a world reputation in photosynthesis research, typified by hosting the 2001 International Photosynthesis Congress. It also has a claim to fame for theoretical work in non-equilibrium thermodynamics concerning production of disorder or entropy, yielding new insights into planetary climates. This experimental project investigates the novel relation between entropy/entropy production and the structure/function of the solar powerhouse of plants (chloroplasts), and addresses fundamental questions at the interface of biology and physics. The research explores chloroplasts as a manifestation of the all-pervading Second Law of Thermodynamics, advancing Australia's contribution to basic science and helping to train researchers.Read moreRead less
New Methods for Structural Biology in Solution. This project aims to expand the range of applications of nuclear magnetic resonance (NMR) spectroscopy in pharmaceutical research, where NMR spectroscopy is already used routinely for the identification of chemical compounds that bind to protein targets.

This project aims to expand the range of applications of nuclear magnetic resonance (NMR) spectroscopy in pharmaceutical research, where NMR spectroscopy is already used routinely for the identification of chemical compounds that bind to protein targets. The techniques developed aim at providing rapid and broadly applicable tools for 3D structure determinations of chemical compounds bound to their protein target, identification of protein-protein interaction sites and characterization of protein motions. The limits of NMR spectroscopy will be pushed to analyse systems of significantly increased molecular weights. The project includes applications to drug targets such as the dengue virus NS2B/NS3 protease.Read moreRead less

The Atomic Force Microscope presents a unique view of the microscopic and molecular world, for it is sensitive to force alone. This instrument can accurately map force over a surface at the molecular scale; picoNewtons at nanometre resolution. The host of intermolecular forces which cause phenomena such as self-assembly, colloid stability, cell interactions and friction are only directly measurable with this technique. In this field of force measurement Australian researchers are leaders. The proposed instrument expands the capabilities of this effort, and develops exciting new directions including the direct manipulation of molecules through a novel feedback and control (haptic) interface.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
