Zeolite A, X and Cancrinite from South African coal fly ash: mechanism of crystallization, routes to rapid synthesis and new morphology
(University of the Western Cape, 2012)
In South Africa, almost 90 % of the country’s electricity is generated from coal combustion. This reliance on coal for energy production is projected to continue in the near and medium term due to the increasing demand for ...
Synthesis & characterization of yttria-stabilised zirconia (YSZ) hollow fibre support for Pd based membrane
(University of the Western Cape, 2013)
Inorganic based membranes which have a symmetric/asymmetric structure have been produced using an immersion induced phase inversion and sintering method. An organic binder solution (dope) containing yttria-stabilised ...
Electrochemical dynamics of cytochrome P450-3A4 isoenzyme biosensor for protease inhibitor antiretroviral drug
(2010)
This thesis firstly reports on the development and characterization of reagent-less and cobalt(III) sepulchrate[Co(Sep)³⁺] mediated biosensor platforms (biosensor platform 1 and biosensor platform 2), with human recombinant ...
Novel adamantane derivatives as multifunctional neuroprotective agents
(University of the Western Cape, 2013)
The pathology of neurodegenerative disorders involves multiple steps, and it is probably for
this reason that targeting one particular step in a multi-step process has only yielded limited
results. Nitric oxide (NO) is ...
Multilayer graphene modified metal film electrodes for the determination of trace metals by anodic stripping voltammetry
(2013)
In this study multilayer graphene nanosheets was synthesize by oxidizing graphite to graphene oxide using H2SO4 and KMnO4 followed by reduction of graphene oxide to graphene using NaBH4. The graphene nanosheets were ...
Coordination polymers as heterogeneous catalysts for oxidation reactions
(University of the Western Cape, 2014)
This study describes the synthesis and characterisation of coordination polymers
complexes of Cu(II) and VO(IV) with two polymeric ligands N,Nʹ -1,2-phenylene bis(5-methylenesalicylidenamine)(L1) and N,Nʹ -1,4-butylene ...
Iridium based mixed oxides as efficient anode catalysts for Solid Polymer Electrolyte (SPE) electrolysers
(2010)
The objective of the thesis is to develop highly efficient catalysts for solid polymer
electrolyte (SPE) electrolyser anodes.The anode is the primary cause of the large overpotential of SPE electrolysers and also adds ...
The design of ultrasensitive immunosensors based on a new multi-signal amplification gold nanoparticles-dotted 4-nitrophenylazo functionalised graphene sensing platform for the determination of deoxynivalenol
(University of Western Cape, 2014)
A highly dispersive gold nanoparticle-dotted 4-nitrophenylazo functionalised graphene
nanocomposite (AuNp/G/PhNO2) was successfully synthesised and applied in enhancing
sensing platform signals. Three label-free ...
The synthesis and electrochemical studies of chalcones and flavanones: an investigation of their antioxidant activity
(University of Western Cape, 2013)
Flavonoids, one of the biggest classes of secondary metabolites, are found abundantly in
nature in a broad range of fruits, vegetables and beverages such as tea, coffee, beer, wine and fruit drinks. Flavonoids have been ...
