Hydrogen selective properties of cesium-hydrogensulphate membranes
(University of the Western Cape, 2006)
The production procedure of a CsHS04-Si02 composite membrane was optimized in order to obtain the highest possible H2:C02 and H2:C~ Idea selectivity permeance. The optimized membrane preparation procedure led to the ...
Oxidative fixation of dinitrogen by photocatalysis
(University of Western Cape, 2000)
The heterogeneous photocatalytic oxidation of dinitrogen to nitrate, NO3 and/or nitrite, no2 using peroxy species of titanium (IV) in aqueous suspensions has been investigated. The photocatalysts used were titanium peroxide ...
The synthesis of the cyclometallated palladium complexes and their applications in olefin oligomerization and in phenylacetylene oligomerization/polymerization
(2007)
This thesis reports the synthesis of the imine ligands from Schiff base condensation reaction of aldehyde derivatives and equimolar quantities of aniline derivatives. The imine ligands spectrometry.
Mononuclear and multinuclear salicylaldimine metal complexes as catalysts precursors in the oxidation of phenol and cyclohexene
(2009)
In this thesis typical homogeneous and dendritic immobilized catalysts derived from
salicylaldimines were investigated as catalysts for the oxidation of hydrocarbons using
hydrogen peroxide as oxidant under aerobic ...
Hydrothermal synthesis and optimisation of zeolite Na-P1 from South African coal fly ash
(2009)
Millions of tonnes of fly ash are generated worldwide every year to satisfy the large demand for energy. Management of this fly ash has been a concern and various approaches for its beneficial use have been investigated. ...
Frequency and voltage-modulated electrochemical aflatoxin b1immunosensor systems prepared on electroactive organic polymer platforms
(2008)
In the presented work, immunosensors for detection of Aflatoxin B1 based on
different immobilization platforms were studied. Synthesis of an electroactive
hydrogel was also carried out. Aflatoxins are a group of mycotoxins ...
Proton conducting polymer composite membrane development for Direct Methanol Fuel Cell applications
(University of Western Cape, 2008)
The objective of this study was thus to prepare highly proton condictivity membranes that are cheap to manufacture and have low methanol permeability.
Geological modeling of the offshore Orange Basin, west coast of South Africa
(UWC, 2009)
Separation between the South American and African plate’s occurred along the present day Atlantic margin during the Middle to Late Jurassic leading to
the formation of a passive margin along the west coast of Southern ...
Evaluation of the leachate chemistry and contaminants attenuation in acid mine drainage by fly ash and its derivatives
(University of the Western Cape, 2006)
The mining industry in South Africa has a huge potential to impact negatively on the environment. Negative impacts include generation of reactive tailings and acid mine drainage (AMD). AMD is highly acidic (pH 2-4), ...
Synthesis, electrodynamics and biosensor applications of novel sulphonated polyaniline nanocomposites
(University of the Western Cape, 2007)
The overall aim of this thesis was to prepare nanostructured more processable heteronuclear sulphonated polyanyline nanocomposites with electroconductive properties suitable for applications in biosensors. The sulphonated ...
