High Pressure Light Scattering Studies of Dense Fluids (Collision, Induced, Lineshape)
… the density dependence of both molecular motion and intermolecular interactions. This thesis describes high pressure light scattering studies of the vibrational relaxation of the nitrate ion in aqueous solutions of sodium nitrate and of collision induced light scattering in methane, sulfur …

Smart-phone-based electrochemical sensor for environmental applications
… with integrated plug-n-play microelectronic ionic sensor that performs electrochemical measurement by using audio jack of a smart phone. This platform was used to measure nitrate concentration using a few microliter liquid samples on field along with providing geospatial map locations through …

The nitrate deposits of rock crevices in the Upper Mississippi Valley
… report of caves containing saltpeter (potassium nitrate) along the Minnesota shore of Lake Pepin, this study located what are thought to be the original caves and revealed a hitherto unsuspected widespread district of cave nitrate deposits in the Upper Mississippi Valley (UMV). Of the 103 caves …

Mineralogical and ion-exchange leaching study of a Rare Earth Element (REE) bearing ion-adsorption clay deposit
… total REE output. This has prompted the evaluation of ion-adsorption clay (IAC) deposits in tropical regions outside China, namely Madagascar. Clay minerals such as kaolinite are part of the phyllosilicate class, containing structures of shared octahedral aluminium and tetrahedral silicon …

Understanding Liquid-Air Interface Corrosion of Steel in Simplified Liquid Nuclear Waste Solutions
… to the liquid-air interface (LAI) corrosion in liquid nuclear waste and in simulants, but a precise understanding of the mechanism is still missing. This work aimed to expand the understanding of the LAI corrosion mechanism.LAI corrosion was found to initiate at the very top of the …

Development of Novel Methodologies for the Electrodeposition of Polypyrrole-based Films in Controlled Morphologies with Potential Application in Nitrate Sensing.
In this thesis the novel electrochemical deposition of poly[N-(2-cyanoethyl)pyrrole] (PPyEtCN) into nanowire and microtube morphologies is reported. Cyclic and pulsed electrochemical techniques were employed to electrodeposit copper micro and nano particles at PPyEtCN and polypyrrole (PPy) …

Development and Characterisation of a Carbon Based pH Microsensor and Studies on Polypyrrole Nanowires
In this thesis the electrochemical deposition of polypyrrole (PPy) into nanowire and bulk morphologies is reported. The electrochemical properties of the different conformations of PPy were examined in order to ascertain their conductivities and surface areas. This could determine the optimisation …
