Catalyst Coated Membranes (CCMs) for polymerelectrolyte Membrane (PEM) fuel cells
(University of the Western Cape, 2010)The main objective of this work it to produce membrane electrode assemblies (MEAs) that have improved performance over MEAs produced by the conventional manner, by producing highly efficient, electroactive, uniform catalyst ... -
The catalytic membrane reactor for the conversion of methane to methanol and formaldehyde under mild conditions
(University of the Western Cape, 2005)This thesis described the development of new catalytic system for the conversion of natural gas (methane) to liquid products such as methanol and formaldehyde. This technology can allow the exploitation of small and medium ... -
A categorical study of persistent homology for closure space
(University of the Western Cape, 2023)We begin with the concept of closure space and show how it relates to other objects like graphs and metric spaces in categorical terms. We also study the notion of simplicial sets and show that there is an adjunction between ... -
Cation-exchanged zeolites-A prepared from South African fly ash feedstock for CO2 adsorption
(University of the Western Cape, 2015)In South Africa coal combustion constitutes up to 90 % of the country’s energy need. This coal combustion activity is known to contribute to the amount of about 40 % of the total CO2 atmospheric emissions worldwide that ... -
Cell culture biomarkers for monitoring of wastewater pollutants
(University of the Western Cape, 2021)Wastewater is normally composed of a mixture of pollutants. The type and composition of pollutants in a particular wastewater depend on the source of origin. The source and characteristics of a particular wastewater determine ... -
Cesium hydrogen sulphate and cesium dihydrogen phosphate based solid composite electrolyte for fuel cell application
(University of the Western Cape, 2004)A new high temperature solid electrolyte composite was developed, with CsHSO4 and CsH2PO4 as the proton conducting material in composition with PTFE and SiO2 to enhance the solid electrolyte composites mechanical strength ... -
Chalcone and curcumin hybrids of indole propargylamines as multifunctional neuroprotective agents
(University of the Western Cape, 2020)Neurodegenerative disorders (NDs) are a range of chronic brain disorders that includes amongst others motor function loss. Parkinson’s disease (PD) is one of the common NDs that has an insidious onset and diagnosed when ... -
The challenge of implementing integrated water resources management (IWRM) in the Lower Okavango River Basin, Ngamiland district, Botswana
(University of the Western Cape, 2005)Water resources management practice has undergone changes in management approaches and principles over time. It was previously characterised by what scholars refer to as the hydraulic mission where ‘extreme engineering’ ... -
Challenges facing researchers conducting clinical trials in HIV prevention in South Africa: a focus on adherence
(University of the Western Cape, 2014)In clinical trials, adherence of the participants to the dosing instructions is a major challenge. Many researchers have identified medication adherence as a topic to further explore in order to obtain good, usable and ... -
Challenges of postgraduate students at the University of the Western Cape 2009 - 2013
(University of the Western Cape, 2019)In South Africa, postgraduate education is a catalyst in national development and poverty alleviation that is widely acknowledged by the state and higher education institutions, such as the University of the Western Cape ... -
Change Management in a Biopharmaceutical Company
(University of the Western Cape, 2020)This study aimed to review the change management implemented in a Biopharmaceutical company in Cape Town in the light of existing literature on change management theory. Three main constructs were identified: process of ... -

Character tables of some selected groups of extension type using Fischer-Clifford matrices
(University of the Western Cape, 2015)The aim of this dissertation is to calculate character tables of group extensions. There are several well developed methods for calculating the character tables of some selected group extensions. The method we study in ... -
Characterisation of a DNA ligase from an Antarctic metagenomic library
(University of the Western Cape, 2011)A metagenomic gene library prepared from soil found beneath a mummified seal carcass in the Miers Valley, Antarctica, suggests an environment rich in uncharacterised biodiversity including enzymes with possible application ... -
Characterisation of a lignocellulosic degrading bacillus strain isolated from thermophilic compost
(University of the Western Cape, 2011)The negative environmental impact of fossil fuels and growing concerns about petroleum supplies has driven the search for alternative, renewable transportation fuels. An 'ideal' fuel replacement would be a biofuel produced ... -
Characterisation of a novel soybean candidate glutathione peroxidase/thioredoxin-dependent peroxidase in soybean exposed to osmotic/drought stress
(University of the Western Cape, 2012)Drought stress is a major contributor to reduced soybean crop yield and quality, this can however be mitigated by the plant’s antioxidant defence mechanisms. One group of antioxidant enzymes that are active in these defence ... -
Characterisation of AtPNP-A - a novel arabidopsis thaliana gene with role in water and salt homeostasis
(University of the Western Cape, 2009)Plant natriuretic peptides (PNPs) are a novel class of extracellular, systemically mobile molecules that elicit a number of plant responses important in homeostasis and growth. Natriuretic peptides were first identified ...
