Synchrotron science is a priority area for Australia, the USA, and most first world countries. Development of new ideas and tools for X-ray investigations is the key to future opportunities and is the subject of this proposal. We will develop new techniques for crystallographic electron-density studies, X-ray Anomalous Fine Structure (XAFS) and Multiple-wavelength Anomalous Dispersion (MAD), and provide useful advances for X-ray lithography and radiography. Simultaneous investigation of form factors, absorption coefficients, anomalous dispersion and X-ray scattering will provide new experimental tests of relativistic atomic wavefunction calculations, molecular bonding and solid state coupled cluster theory. Major discrepancies will be resolved.Read moreRead less
Surface Forces in Aqueous Electrolytes. This project studies the force between two nearby colloidal particles or macromolecules in aqueous electrolyte solutions. Although such forces control the approach and binding of particles in electrolytes and hence have large practical significance they are poorly known. In recent work I established a rigorous scheme for calculation of the electrostatic contribution to the force and proved its feasibility. In order to realise practical applications, such a ....Surface Forces in Aqueous Electrolytes. This project studies the force between two nearby colloidal particles or macromolecules in aqueous electrolyte solutions. Although such forces control the approach and binding of particles in electrolytes and hence have large practical significance they are poorly known. In recent work I established a rigorous scheme for calculation of the electrostatic contribution to the force and proved its feasibility. In order to realise practical applications, such as in drug design, we must know the mean force between an ion and a surface or functional surface group. Here I propose to perform the required simulations and explore the analytical simplifications.Read moreRead less
