Description
Summary:Thesis (M.Sc.)--Memorial University of Newfoundland, 2008. Physics and Physical Oceanography Includes bibliographical references (leaves 67-71). Pulsed field gradient nuclear magnetic resonance (NMR) experiments were performed on hard-sphere-like colloidal suspensions. We synthesized NMR-visible colloidal particles and measured spectrally resolved diffusion coefficients for monodisperse suspensions of different size particles. Results of these experiments show good agreement with theoretical expectation. We also probed a bidisperse (binary) colloidal suspension successfully and obtained the diffusion coefficients of two species simultaneously. The colloidal model system developed in this work will allow the study of colloidal phase behaviour in binary mixtures for different number and size ratios.
