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 Isolation and Electrochemical Studies of Flavanoids from Galenia africana and Elytropapus rhinocerotis from the North Western Cape
(University of the Western Cape, 2010)
In this study two medicinal plant species, namely Galenia africana and Elytropapus rhinocerotis, the former belonging to the family Aizoceae and the latter belonging to the family Asteraceae, have been investigated and ...
Development of a small-scale electro-chlorination system for rural water supplies
(2010)
To address the urgent need for safe potable water in South Africa’s rural areas,
sustainable systems for water disinfection at the village-scale of operation are required.In this thesis, the development of a small-scale ...
Development of electrochemical sensors containing bimerallic silver and gold nanoparticles
(University of the Western Cape, 2010)
Polyaromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants that have been shown to be teratogenic, mutagenic and carcinogenic and pose serious threats to the health of aquatic and human life. Several methods ...
Development of electrochemical ZnSe Quantam dots biosensors for low-level detection of 17β-Estradiol estrogenic endocrine disrupting compound
(University of the Western Cape, 2010)
The main thesis hub was on development of two electrochemical biosensors for the determination of 17β-estradiol-estradiol: an estrogenic endocrine disrupting compound. Endocronology have significantly shown that the endocrine ...
Boron-doped Diamond Sensors for the Determination of Organic Compounds in Aqueous Media
(University of the Western Cape, 2010)
In electrochemical oxidation treatment of wastewater, the electrode material is an important parameter in optimizing oxidative electrochemical processes, since the mechanism and products of several anodic reactions are ...
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 ...
Nanocomposite-graphene based platform for heavy metal detection
(University of the Western Cape, 2010)
This study reports the synthesis of graphene by oxidizing graphite to graphite oxide using H2SO4 and KMnO4 and reducing graphene oxide to graphene by using NaBH4. Graphene was then characterized using FT-IR, TEM, AFM, XRD, ...
Synthesis, characterization and catalytic application of carbonyl complexes of molybdenum and tungsten in epoxidation of some alkenes
(University of the Western Cape, 2010)
In this thesis we describe the synthesis of several carbonyl complexes of molybdenum and tungsten, compounds (Cl-ClO). The compounds Cl- C4 are zero valent carbonyl complexes containing N-base ligands prepared by following ...
Electrochemical characterization of nanostructured SnO2 and TiO2 for potential application as dielectric materials in sulfonated-polyaniline based supercapacitors
(University of the Western Cape, 2010)
In this research project, nanostructured composites based on Tin dioxide (SnO2) and Titanium dioxide (TiO2) with poly-4-styrene sulfonic acid (PSSA) doped polyaniline (PANI) conducting polymer has been investigated based ...
