Optimisation of biodiesel production via different catalytic and process systems
(University of the Western Cape, 2011)
The production of biodiesel (methyl esters) from vegetable oils represents analternative means of producing liquid fuels from biomass, and one which is growing rapidly in commercial importance and relevance due to increase ...
Phytochemical and antimicrobial studies on Rhus natalensis
(University of the Western Cape, 2011)
Extracts from the root bark, stem bark, and leaves of R. natalensis were screened for antibacterial activity against standard bacterial strains; Staphylococcus aureas, Escherichia coli and Pseudomonas aureginosa, and fungi; ...
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 ...
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 ...
Nanoparticulate of silver-modified poly (8-anilino-1-naphthalene sulphonic acid) nanobiosensor systems for the determination of Tuberculosis treatment drugs
(University of the Western Cape, 2011)
This study firstly reports the development and characterization of PVP-AgNPs, PANSA and PVPAgNPs/ PANSA nanocomposite on gold. AFM and TEM analyses revealed highly electroactive nanocomposites whose morphogy and properties ...
Synthesis and characterization of micro- and mesoporous materials for low temperature selective catalytic reduction of nitrogen oxides
(University of the Western Cape, 2011)
In summary, it has been shown during this study that bimetallic Fe and Mn containing catalysts can be prepared by wet impregnation and not by ion exchange because of the competition between two different metals at different ...
Polymeric tyrosinase nanobiosensor system for the determination of endocrine disrupting bisphenol A
(University of the Western Cape, 2011)
The main objective of this work was to develop simple and sensitive electrochemical sensors for the detection of bisphenol A. To investigate the electrochemical behavior of BPA on a bare glassy carbon electrode. To apply ...
Determination of fumonisins in maize by High Performance Liquid Chromatography with fluorescence and ultraviolet detection of o-phthaldialdehyde, naphthalene-2,3-dicarboxaldehyde and dansyl chloride derivatives
(University of the Western Cape, 2011)
Fumonisins, carcinogenic mycotoxins produced by various Fusarium species, occur naturally in maize and maize-based food products. They are hazards for animal and human health as they cause cancer in rodents and have been ...
Cytochrome C biosensor for the determination of trace level arsenic and cyanide compounds
(University of the Western Cape, 2011)
In this work, an electrochemical method based on a cyt c biosensor has been developed, for the detection of selected arsenic and cyanide compounds. Boron Doped Diamond (BDD) electrode was used as a transducer, onto which ...
