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 ...
The electrogeneration of hydroxyl radicals for water disinfection
(University of the Western Cape, 2006)
This study has shown that OHË radicals can be generated in an Fe/O2 cell from the electrode products via Fenton’s reaction and used for water disinfection. The cell system in which the experiments were carried out ...
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 ...
Hydrogen selective properties of cesium-hydrogensulphate membranes
(University of the Western Cape, 2006)
Over the past 40 years, research pertaining to membrane technology has lead to the development of a wide range of applications including beverage production, water purification and the separation of dairy products. For the ...
Synthesis and electrochemical characterisation of conducting polyaniline-fly ash matrix composites
(2005)
The aim of this study was to produce useful composite materials from fly ash, a major waste product of coal combustion from power plants. Polyaniline-fly ash (PANI-FA) composites were prepared by in situ polymerisation of ...
Composite low temperate hydrogen storage material on the basis of iron-titanium alloy ; synthesis and structure
(University of the Western Cape, 2006)
It is widely believed that hydrogen will within a few tens of years become the means of storing and transporting energy. The reason is the depletion of hydrocarbons and the
relatively facile production of hydrogen from ...
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 ...
Electrochemical studies of monosubstituted squarate ligands and its transition metal and lanthanide complexes
(University of the Western Cape, 2008)
The study introduces and puts forward Sector Policing as a model to expand community Policing and to broaden the scope of crime prevention. It also demonstrates how Sector Policing can be utilised to decentralise policing ...
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 ...
