Mononuclear and multinuclear salicylaldimine metal complexes as catalysts precursors in the oxidation of phenol and cyclohexene
(2009)
In this thesis typical homogeneous and dendritic immobilized catalysts derived from
salicylaldimines were investigated as catalysts for the oxidation of hydrocarbons using
hydrogen peroxide as oxidant under aerobic ...
Frequency and voltage-modulated electrochemical aflatoxin b1immunosensor systems prepared on electroactive organic polymer platforms
(2008)
In the presented work, immunosensors for detection of Aflatoxin B1 based on
different immobilization platforms were studied. Synthesis of an electroactive
hydrogel was also carried out. Aflatoxins are a group of mycotoxins ...
Proton conducting polymer composite membrane development for Direct Methanol Fuel Cell applications
(University of Western Cape, 2008)
The objective of this study was thus to prepare highly proton condictivity membranes that are cheap to manufacture and have low methanol permeability.
Evaluation of the leachate chemistry and contaminants attenuation in acid mine drainage by fly ash and its derivatives
(University of the Western Cape, 2006)
The mining industry in South Africa has a huge potential to impact negatively on the environment. Negative impacts include generation of reactive tailings and acid mine drainage (AMD). AMD is highly acidic (pH 2-4), ...
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 ...
Preparation and physico-chemical properties of nickel nanostructured materials deposited in etched ion-track membrane
(University of the Western Cape, 2005)
The development of finely dispersed powders and superfine-grained materials intended for application in various areas of science and engineering is one of the challenges facing modern nanotechnology. Thus, specific fundamental ...
An investigation into the synthesis, characterisation and some applications of novel metal-containing polymers and dendrimers of transition metals
(University of the Western Cape, 2003)
metal-containing complexes, that exhibit enhanced chemical and physical properties. This thesis describes the synthesis of new metal-containing linear polymers and dendritic molecules.
Chapter 1 presents an overview of ...

Composite poly(dimethoxyaniline) electrochemical nanobiosensor for glufosinate and glyphosate herbicides
(University of the Western Cape, 2008)
In this thesis, I present a simple, sensitive and low cost electrochemical nanobiosensor for quantitative determination of the herbicides glufosinate, glyphosate and its metabolite aminomethylphosphonic acid (AMPA). Firstly, ...
Synthesis and characterization of nanofluids for cooling applications
(University of the Western Cape, 2006)
Low thermal conductivity is a primary limitation in the development of energy-efficient heat transfer fluids that are required in numerous industrial sectors. Recently submicron and high aspect ratio particles (nanoparticles ...
