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 ...
Amperometric biosensor systems prepared on poly (aniline-ferrocenium hexafluorophosphate) composites doped with poly(vinyl sulfonic acid sodium salt)
(University of the Western Cape, 2008)
The main hypothesis in this study is the development of a nanocomposite mediated amperometric biosensor for detection of hydrogen peroxide. The aim is to combine the electrochemical properties of both polyaniline and ...
Electrochemical Characterization of Platinum based anode catalysts for Polymer Exchange Membrane Fuel Cell
(University of the Western Cape, 2008)
In this study, the main objective was to investigate the tolerance of platinum based binary anode catalysts for CO poisoning from 10ppm up to1000ppm and to identify the best anode catalysts for PEMFCs that tolerates the ...
Treatment of brines using commercial zeolites and zeolites synthesized from fly ash derivative
(University of the Western Cape, 2008)
The objectives of this project was to ameroliate two waste materials, namely Acid Mine Drainage and Fly Ash and recover the solid residues for conversion into an adsorbent to treat brine. The solid residues were then ...
Synthesis and electrochemical modulation of the actuator properties of poly(phenazine-2,3-diimino (pyrrol-2-yl))
(University of the Western Cape, 2008)
The focus of this study is to synthesize a novel hinged polymer actuator. The linking molecule (hinge) is phenazine with interconnected dipyrrole units.
Phytochemical study of Rhoicissus tomentosa
(University of the Western Cape, 2008)
This investigation focused on Rhoicissus tomentosa, belonging to the family, Vitaceae in an attempt to assess the phytochemistry of this plant which is widely used by traditional healers in South Africa to ensure the safe ...
Treatment of brines using commercial zeolites and zeolites synthesized from fly ash derivative
(University of the Western Cape, 2008)
South Africa is one of the countries that have scarce natural resources that they have to preserve what is available at their disposal. South Africa is also fast becoming one of the countries with major industrial development. ...
Chemical compositions and leaching behaviour of some South African fly ashe
(University of the Western Cape, 2008)
Fly ash is the most abundant of the waste materials generated from coal combustion in coal-fired power stations. South Africa uses more than 100 million tonnes of low grade bituminous coal annually to produce cheap electricity ...
