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) ...
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 ...
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 ...
The synthesis and evaluation of potential anti-Mycobacterium tuberculosis and apoptotic agents
(University of the Western Cape, 2007)
Tuberculosis (TB) and Cancer are among the most devastating and therapeutically challenging diseases that need to be addressed in South Africa today. The development of muti-drug resistance in TB causing bacteria, Mycobacterium ...
Development of polyaniline nanotube electrocatalysts and sesor devices for phenolic-pollutants
(University of the Western Cape, 2007)
As a source of life, water is one of the most precious commodities for all living organisms. Water resources are reported to be declining in numbers or the amount of water present and the existing onses are being polluted ...
Chemical and biological investigation into some selected African indigenous medicinal plants
(University of the Western Cape, 2009)
African medicinal plants are commonly used throughout Africa to treat a variety of ailments including wounds and ulcers, cough and chest complaints, gingivitis, fever and gonorrhoea, indication all related to infection and ...
Development of new dendritic ligands for copper mediated Atom Transfer Radical Polymerization (ATRP) of methyl methacrylate
(University of the Western Cape, 2007)
A variety of nitrogen based dendritic ligands have been synthesized and used in copper mediated Atom Transfer Radical Polymerization (ATRP) of MMA. These ligands were derived from the commercially available Generation 1 ...
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 ...
The development of inorganic and organic/inorganic membranes for DMFC application
(University of the Western Cape, 2004)
A fuel cell is an energy device that converts chemical energy to electrical energy. Low temperature fuel cells, namely the hydrogen fuel cell and the direct methanol fuel cell are preferred amongst other fuel cell types ...
The catalytic membrane reactor for the conversion of methane to methanol and formaldehyde under mild conditions
(University of the Western Cape, 2005)
This thesis described the development of new catalytic system for the conversion of natural gas (methane) to liquid products such as methanol and formaldehyde. This technology can allow the exploitation of small and medium ...
