(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, 2002)Solar radiation is the main energy source for the Earth's climate system and determination of the amount of solar radiation that reaches the surface is extremely important. The solar spectrum is most intense in the ... -
(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, 2008)Dissolved organic matter (DOM) is the most dynamic and least understood part of the global oceanic carbon cycle. Furthermore the molecular composition of DOM is largely unknown. This study focused on the distribution ...

(Thesis, Master of Science, 1946)
-
(Thesis, Doctor of Philosophy, 2012)A series of pyrimidine-hydrazone (pym-hyz) molecular strands have been modified with terminal hydroxymethyl and acryloyl functional groups in order to allow their incorporation into co-polymer gels. This thesis describes ...
-
(Thesis, Master of Science, 2012)This thesis investigates the use of Raman spectroscopic techniques for analysing paint and dairy samples (milk powder and model cheese systems). Several samples of paint from a painting called ‘Hope’ by Edward Burne-Jones ... -
(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)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)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)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, 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)This thesis has identified a suite of hydrocarbon diagnostic indices to be applied in the forensic fingerprinting of diesel oil characterisation and source identification using compound-specific isotope analysis (CSIA). ...
-
(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 ...
