(Thesis, Doctor of Philosophy, 2013)Diphenylamine-2,2’-dicarboxaldehyde (1a) was prepared in three steps from ethyl-2-iodobenzoate and ethyl-2-aminobenzoate (38% overall yield) following the literature synthesis. The intermediate diphenylamine-2,2’-ethylbenzoate ...
-
(Thesis, Doctor of Philosophy, 2013)Phosphorus (P) compounds play a vital rule in living processes and are essential not only for hereditary processes, but for the growth, development, and maintenance of all plants and animals. Current biogeochemical models ... -
(Thesis, Master of Science, 2013)Nitrogen (N) is a major element in protein synthesis and is often the limiting nutrient in aquatic environments. As N availability is tightly coupled with carbon (C) uptake, it also has the potential to impact on species ... -
(Thesis, Doctor of Philosophy, 2013)Cysteine dioxygenase (CDO) is a non-heme mono-iron enzyme that catalyses the oxidation of cysteine to cysteine sulfinic acid (CSA) by the addition of the two oxygen atoms from dioxygen to the thiol group of cysteine. In ...
-
(Thesis, Doctor of Philosophy, 2012)Organic contaminants have become widespread in the environment due to the high consumption of materials in the modern lifestyle. The contamination of surface aquatic systems can be particularly crucial because pollutants ...
-
(Thesis, Doctor of Philosophy, 2012)The project detailed in this thesis was a successful attempt to prepare diphenylamine- and carbazole-based dialdehyde units; a handful of metal-free [2+2] macrocycles; and a selection of complexes which represent a first ...
-
(Thesis, Doctor of Philosophy, 2012)Oceanographic studies in the last three decades have provided insights on the correlation between cadmium (Cd) and phosphate (PO43-) in seawater. That the concentrations of these two are closely related ...
-
(Thesis, Doctor of Philosophy, 2012)Semi-volatile organic contaminants (SOCs) have the ability to undergo long-range atmospheric transport to remote ecosystems like Antarctica. Very little is known about current SOC trends in fish from the McMurdo Sound ...
-
(Thesis, Master of Science, 2012)The aim of this work is to improve the swelling response of redox active hydrogel actuators. At the moment, complete swelling of our quinone based actuators takes about 150 minutes and that of our 2,2,6,6-tetramethylpipe ... -
(Thesis, Doctor of Philosophy, 2012)Seawaters associated with the Subtropical Frontal Zone located off the eastern coast of New Zealand are of particular interest for studies of the global marine carbon cycle. The Southland Front represents the near-coastal ... -
(Thesis, Doctor of Philosophy, 2012)This thesis details a study of Re(I) and Cu(I) metal polypyridyl complexes based on different polypyridyl ligand systems, with the aim of understanding the nature of their excited state properties. This project is focussed ...
-
(Thesis, Master of Science, 2012)This thesis describes the investigation of the supramolecular chemistry of two closely related bent ligands 4,4'–dipyridyl ketone (L1) and 4,4'–dipyridyl ketoxime (L2) with a range of Ag(I), Cu(I) and Cu(II) salts. ...
-
(Thesis, Doctor of Philosophy, 2012)A number of polypyridyl complexes based on d6 metals have been investigated using a range of spectroscopic and computational techniques. Interest in these systems stems from potential applications in molecule based devices, ...
-
(Thesis, Doctor of Philosophy, 2012)The effect of head group modification on the solubility and antimicrobial potency of some quaternary nitrogen surfactants (QNSs) was investigated. Using high yielding Menshutkin reactions, a homologous series of monomeric, ...
-
(Thesis, Master of Science, 2012)Supramolecular chemistry has attracted a lot of attention due to a diversity of applications based on the aggregation of molecules through non-covalent interactions. One molecule enveloping another molecule through these ...
-
(Thesis, Doctor of Philosophy, 2012)The work presented in this thesis encompasses an investigation into a number of porphyrin species. All of this work has a central focus on analysis of the porphyrin electronic structure and within the context of photovoltaics. ... -
(Thesis, Doctor of Philosophy, 2012)Atmospheric monitoring and the determination of geographic sources of semi-volatile organic contaminants (SOC) are becoming increasingly important given the ability of SOCs to volatilise, undergo long-range atmospheric ...
-
(Thesis, Master of Science, 2012)
-
(Thesis, Doctor of Philosophy, 2012)The aim of the present work was to contribute to an understanding of the reactivity of hydroxylated zirconia surfaces towards hydration and anion adsorption. IR spectroscopy was used to characterise the structure and bonding ...
-
(Thesis, Doctor of Philosophy, 2012)Two fully lipidated phosphatidylinositol dimannosides (Ac2PIM2s), (16:0, 16:0)(16:0/16:0)-PIM2 1 containing four palmitoyl residues and (16:0, 18:0)(19:0/16:0)-PIM2 2 containing three different acyl residues were synthesised. ...
