Background
Catherine Whitby is a physical chemist with expertise in surface and interfacial chemistry. Her PhD project was an atomic force microscope and electrokinetic study of the molecular structure of inorganic, surfactant and polymeric adsorbed layers on inorganic substrates and the function of the adsorbed layers in particle interactions. At the University of Hull (2001-2005), she investigated the formation, structure and flow behaviour of emulsions stabilized by nanoparticles. At the University of Sydney, she worked as a Gritton Postdoctoral Fellow (2005-2006) studying emulsions using electroacoustic and neutron scattering techniques. Catherine joined the Ian Wark Research Institute at
UniSA in late 2006.
Research Interests
Her current research interests are related to the interactions between particles and fluid interfaces, including the formation, stability, structure and flow behaviour of particle-stabilised emulsions and foams, the selective attachment of particles to fluid interfaces, nanoparticle encapsulation, the diffusion of nanoparticles to fluid interfaces and the charging behaviour of nanoparticles adsorbed at fluid interfaces.
Current Projects
Controlled attachment of very small particles and bubbles to interfaces (AMSRI 4.1)
Selective coagulation of fine particles (AMSRI 4.2)
Role of Brownian diffusion in flotation (AMSRI 3.3)
