Development of novel hypervalent iodine conjugation strategies towards pneumococcal conjugate vaccines
(2013)
Invasive pneumococcal disease (IPD), which includes potentially fatal conditions such as meningitis, septicaemia and pneumonia poses a threat in children aged <5 years, pneumonia being the leading cause of child mortality ...
Metallodendrimers as catalysts for C-C coupling reactions
(2011)
In this work, we describe the synthesis of ferrocenylimine and G1 dendrimeric N,N′ ligands, and their palladium(II) complexes. The ligands L1 – L4 were synthesized following Schiff base condensation reactions. The ...
Development of a small-scale electro-chlorination system for rural water supplies
(2010)
To address the urgent need for safe potable water in South Africa’s rural areas,
sustainable systems for water disinfection at the village-scale of operation are required.In this thesis, the development of a small-scale ...
Development of electrochemical sensors containing bimerallic silver and gold nanoparticles
(University of the Western Cape, 2010)
Polyaromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants that have been shown to be teratogenic, mutagenic and carcinogenic and pose serious threats to the health of aquatic and human life. Several methods ...
Development of electrochemical ZnSe Quantam dots biosensors for low-level detection of 17β-Estradiol estrogenic endocrine disrupting compound
(University of the Western Cape, 2010)
The main thesis hub was on development of two electrochemical biosensors for the determination of 17β-estradiol-estradiol: an estrogenic endocrine disrupting compound. Endocronology have significantly shown that the endocrine ...
Boron-doped Diamond Sensors for the Determination of Organic Compounds in Aqueous Media
(University of the Western Cape, 2010)
In electrochemical oxidation treatment of wastewater, the electrode material is an important parameter in optimizing oxidative electrochemical processes, since the mechanism and products of several anodic reactions are ...
Electrolytic determination of phthalates organic pollutants with n nostructured titanium and iron oxides sensors
(University of the Western Cape, 2010)
This work reports the chemical synthesis, characterisation and electrochemical application of titanium dioxide (TiO2) and iron oxide (Fe2O3) nanoparticles in the determination of phthalates. The other part of this work ...
Electrochemical energy conversion using metal hydrides hydrogen storage materials
(University of the Western Cape, 2010)
Metal hydrides hydrogen storage materials have the ability to reversibly absorb and release large amounts of hydrogen at low temperature and pressure. In this study, metal hydride materials employed as negative electrodes ...
Synthesis, characterization and physicochemical properties of platinum naboparticles on ordered mesoporous carbon
(University of the Western Cape, 2011)
In this study SBA-15 mesoporous silica template was synthesized and used as a sacrificial template in the preparation of ordered mesoporous carbon material. A chemical vapour deposition (CVD) technique using LPG or ...
Ion track modification of polyimide film for development of palladium composite membrane for hydrogen separation and purification
(University of the Western Cape, 2011)
South Africa s coal and platinum mineral resources are crucial resources towards creating an alternative and environmentally sustainable energy system. The beneficiation of these natural resources can help to enhance a ...
