King, Andrew2023-06-072023-06-072007https://unbscholar.lib.unb.ca/handle/1882/34398In this project I have measured the molecular self-diffusion coefficient of water in order to quantify the effects of dissolved gas concentration upon self-diffusion. It has been shown that degassing water samples has enhanced the stability of oil-in- water emulsions formed without the aid of stabilizers such as surfactants and polymers 1. Degassing enhances water's ability to work as a solvent of non-polar molecules. There are electrical conductivity changes in the water when it is completely degassed; such a change demonstrates that there is a change in molecular structure. This leads to an interest in the self-diffusion behaviour of the water under these conditions2. The project began with optimization of the phase cycling scheme for the NMR Cotts-13 interval sequence, which measures self-diffusion in the presence of local magnetic field inhomogeneity. This technique development allowed us to measure the self-diffusion coefficient of the water samples that are degassed and non-degassed.ii, 36 pageselectronicen-CAhttp://purl.org/coar/access_right/c_16ecsenior reportPhysics
