The synthesis of the cyclometallated palladium complexes and their applications in olefin oligomerization and in phenylacetylene oligomerization/polymerization
(2007)
This thesis reports the synthesis of the imine ligands from Schiff base condensation reaction of aldehyde derivatives and equimolar quantities of aniline derivatives. The imine ligands spectrometry.
Synthesis, electrodynamics and biosensor applications of novel sulphonated polyaniline nanocomposites
(University of the Western Cape, 2007)
The overall aim of this thesis was to prepare nanostructured more processable heteronuclear sulphonated polyanyline nanocomposites with electroconductive properties suitable for applications in biosensors. The sulphonated ...
Metal complexes based on monomeric and dendrimeric pyrrole-imine ligands as catalytic precursors
(University of the Western Cape, 2007)
Over the recent past, organometallic chemistry has grown and the impact of catalytic applications in various chemical technologies has rapidly evolved from the realm of academic laboratories into full-scale industrial ...
Nanostructured polypyrrole impedimetric sensors for anthropogenic organic pollutants
(University of the Western Cape, 2007)
Polypyrrole composites of polyaromatic hydrocarbon sulphonic acids (β–naphthalene sulphonic acid (NSA) and 1, 2-napthaquinone-4-sulphonic acid (NQS)), as well as those of transition metal oxides (tungsten (VI) oxide (WO3) ...
The hydrochemical characteristics of groundwater in the Incomati Estuary
(University of the Western Cape, 2007)
The focus of this work was to monitor and evaluate the hydrochemical characteristics of the groundwater in the Incomati Estuary for a period of one year. The aims of this work were to evaluate the groundwater chemistry ...
Electrochemical dynamics of cytochrome P450 (2D6) biosensors for selective serotonin re-uptake inhibitors (SSRIs)
(University of the Western Cape, 2007)
Selective serotonin re-uptake inhibitors (SSRIs) are a new class of antidepressants used mainly for the treatment of depression and other forms of related disorders. There are a number of side effects associated with these ...
Mercaptobenzothiazole-on-Gold Biosensor Systems for Organophosphate and Carbamate Pesticide Compounds
(University of the Western Cape, 2007)
This study firstly reports the development, characterisation, and application of thick-film acetylcholinesterase (AChE) biosensors based on a gold electrode modified with a mercaptobenzothiazole (MBT) self-assembled monolayer ...
Biological properties of selected flavonoids of rooibos (Aspalathus linearis)
(University of the Western Cape, 2007)
Bioactivity-guided fractionation was used to identify the most potent antioxidant and antimutagenic fractions contained in the methanol extract of unfermented rooibos (Aspalathus linearis), as well as the bioactive principles ...
The preparation of binuclear and polynuclear methyl complexes of palladium as catalyst precursors in phenylacetylene polymerization
(University of the Western Cape, 2007)
This study focused on the development of binuclear and multinuclear catalyst for use in vinylic monomer oligomerization and polymerization. The main objective was to develop new homogeneous catalysts systems with hopefully ...
Immobilized catalysts for alkene oxidation
(University of the Western Cape, 2007)
Tertiary butyl substituted and unsubstituted Schiff base systems containing N,O donor ligands (Salicylaldimines) with aminotriethoxysilane tail were synthesized and complexed to Copper and Cobalt acetate. The ligands were ...
