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 ...
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) ...
Advanced oxidative water treatment process using an electrohydraulic discharge reactor and TiO2 immobilised on nanofibres
(University of Western Cape, 2013)
The aim of this study was to design and build an electrohydraulic discharge reactor in such a way that the synthetic immobilized TiO2 nanophotocatalytic components could be integrated, for the production of active species ...
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 ...
