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 ...
Pyridine carboxamide and pyrazole palladium(II) complexes as catalyst precursors for phenylacetylene polymerization
(University of the Western Cape, 2005)
The objectives of this project were to synthesize and characterise pyridine carboxamide ligands and their palladium complexes and investigate their catalytic activity in the polymerization process of phenylactylene.
Synthesis and characterisation of proton conducting membranes for direct methanol fuel cell (DMFC) applications
(University of the Western Cape, 2005)
For a direct methanol fuel cell (DMFC), the proton exchange membrane must conduct protons and be a good methanol barrier. In addition to the high methanol permeability achieved by these membranes, they are very expensive ...
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 ...
Studies on some biologically active natural products from Tulbaghia Alliacea
(University of the Western Cape, 2005)
It is believed that early humans had knowledge of how to use traditional medicinal plants, but the knowledge has been partially lost as society underwent various changes leading to new civilizations. The aim of this study ...
Fabrication and kinetic modeling of cytochrome P4502D6 amperometric biosensors for serotonin reuptake inhibitors
(University of the Western Cape, 2005)
An amperometric biosensor was prepared by in situ deposition of cytochrome P4502D6 (CYP2D6, P4502D6) enzyme on a polyaniline (PANI)-doped glassy carbon electrode. The PANI film was electrochemically deposited on the electrode ...
The application of high capacity ion exchange absorbent material, synthesized from fly ash and acid mine drainage, for the removal of heavy and trace metals from secondary co-disposed process waters
(University of the Western Cape, 2005)
The objective of this study was to investigate the feasibility of the application of low cost high capacity inorganic ion exchange material, synthesized form collected fly ash and acid mine drainage solid residues, for the ...
Polymer/nano-organic composite proton exchange membranes for direct methanol fuel cell application
(University of the Western Cape, 2005)
The proton exchange membrane is one key component of direct methanol fuel cells, which has double functions of conducting protons, separating fuels and oxidant. At present, the performance and price of sulfonic acid proton ...
Characterization of platinum-group metal nanophase electrocatalysts employed in the direct methanol fuel cell and solid-polymer electrolyte electrolyser
(University of the Western Cape, 2005)
Characterization of nanophase electrocatalysts, which are an essential part in the direct methanol fuel cell (DMFC) and solid-polymer electrolyte (SPE) electrolyser, have been studied in this work. Their nanoparticulate ...
The synthesis of 3-allyl-4-ethyl-2- (1'-hydroxyethyl)-1-methoxynaphthalene and its behaviour towards base- and palladium-promoted cyclisation under aerobic and anaerobic conditions
(University of the Western Cape, 2005)
Over the years, Giles and co-workers have established that, upon treatment with potassium tert-butoxide, tetra-substituted naphthalenes undergo cyclisations to afford naphthopyrans. It was suggested that these base-induced ...
