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.

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, ...
Pt Nanophase supported catalysts and electrode systems for water electrolysis
(University of the Western Cape, 2008)
In this study novel composite electrodes were developed, in which the catalytic components were deposited in nanoparticulate form. The efficiency of the nanophase catalysts and membrane electrodes were tested in an important ...
Synthesis of multi-metallic catalysts for fuel cell applications
(University of the Western Cape, 2008)
The direct methanol fuel cell or DMFC is emerging as a promising alternative energy source for many applications. Developed and developing countries, through research, are fast seeking a cheap and stable supply of energy ...
Electrochemical impedance modelling of the reactivities of dendrimeric poly(propylene imine) DNA nanobiosensors
(University of the Western Cape, 2008)
In this thesis, I present the electrochemical studies of three dendrimeric polypropylene imine (PPI) nanomaterials and their applications as a platform in the development of a novel label free DNA nanobiosensor based on ...
Palladium surface-modified rare earth metal-based ab5 type hydride-forming materials
(University of the Western Cape, 2008)
Driven by mounting standards of living and a growing population, South African energy consumption is expected to increase dramatically within the next decade. The increased demand for more energy will require enormous ...
