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 ... -
