Electrochemiluminescence of novel polyanilino-rutheniumbipyridyl-imidazo phenanthroline and carboxy-difluoroboradiazaindacene luminophores
(University of the Western Cape, 2015)Electrochemiluminiscence, (ECL), is an electrochemically-induced process that leads to the generation of measurable luminescent signals at the electrode surface. The luminescent signals occur when electrochemically generated ... -
Electrochemistry and photophysics of carbon nanodots-decorated nigs(Ni(In, Ga)Se2) quantum dots
(university of western cape, 2020)Currently, non-renewable sources are mostly used to meet the ever-growing demand for energy. However, these sources are not sustainable. In addition to these energy sources being not sustainable, they are bad for the ... -
Electrodeposition of multi-valent metal oxides at 1-methyl-3-octylimidazolium bis(trifluoromethylsulfonyl) imide ionic liquid - carbon paste electrode
(University of the Western Cape, 2012)A study on carbon paste electrode (CPE) materials containing 1-methyl-3-octylimidazolium bis (trifluoromethylsulfonyl) imide [MOIM[Tƒ2N] – a hydrophobic room temperature ionic liquid (IL) - is reported. CPEs with (a) the ... -
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 ... -
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 ... -
Electronic nicotine delivery systems : approach to regulation in South Africa
(University of the Western Cape, 2015)Background: The explosion in the popularity and use of e- cigarettes over the last decade has raised concerns and incited intense discussions over their safety, efficacy and potential public health impact. Globally there ... -
An electrophysiological exploration into the Sertoli cell, utilizing plant extracts with a view to contraception
(University of the western cape, 2003)Certa in medicinal plant extracts have been shown to have a contraceptive effect on male rats (Rajasekaran et al. , 1988) and mice (Kong et al., 1986). A possible site for the mechanism of action has been identified as the ... -
Electropolymerization and electrochromism of poly(4,7-dithien-2-yl-2,1,3-benzothiadiazole) and its copolymer with 3-methoxythiophene in ionic liquids
(2013)This thesis is based on the study of electropolymerization and electrochromism of poly(4,7- dithien-2-yl-2,1,3-benzothiadiazole) (P(DTBT) and its copolymer with 3-methoxythiophene (MOT) in imidazolium ionic liquids (ILs) ... -
Electrospinning of porous composite materials for hydrogen storage application
(University of the Western Cape, 2016)Due to the rapid depletion of fossil fuel reserves and the production of environmentally harmful by-products such as carbon dioxide, there is an urgent need for alternate sustainable clean energy. One of the leading ... -
Elementary logic as a tool in proving mathematical statements
(University of the Western Cape, 2008)The findings of the study indicate that knowledge of logic does help to improve the ability of students to make logical connections (deductions) between and from statements.The results of the study, however, do not indicate ... -
Elementary Logic as a Tool in Proving Mathematical Statements
(University of the Western Cape, 2008)An analysis of South African school mathematics results indicates that one of the problem areas in the mathematical performance of learners is proof and proving. In an endeavour to improve the mathematical proving ability ... -
Ellection markup language (EML) based tele-voting system
(University of the Western Cape, 2009)Elections are one of the most fundamental activities of a democratic society. As is the case in any other aspect of life, developments in technology have resulted changes in the voting procedure from using the traditional ... -
Emerging farmers in water user associations cases from the Breede Water Management area
