Optical and microarray silver-gold based sensors for the detection of e.coli 0157:h7 in seawater
(University of the Western Cape, 2021)
Recently researchers reported that nanoparticles functionalised through chemical methods possess risks to the environment and to the human health since they use hazardous chemicals and produce toxic waste. The increasing ...
Photovoltaic and gas sensing applications of transitional metal nanocomposites of poly(3-hexylthiophene)-titanium dioxide
(University of Western Cape, 2021)
This thesis starts with the reviewing of studies on the loading of noble metals and nanostructured metal oxides into bulk heterojunction organic solar cell device architectures. The reviews focused on the innovative ...
A modified Adams fusion method for the synthesis of binary metal oxide catalysts for the oxygen evolution reaction
(University of Western Cape, 2020)
The majority of the global energy is sourced from conventional fossil fuels. The high demand for energy is accelerating along with the depletion of these fossil fuels. Hence, the shift to renewable energy sources and ...
Graphene modified Salen ligands for the electrochemical determination of heavy metal ions
(University of Western Cape, 2020)
Environmental pollution is a major threat to all life, which needs to be addressed. Heavy metals are well-known environmental pollutants due to their toxicity and, persistence in the environment toxicity for living organisms ...
Aluminium and gold functionalized graphene quantum dots as electron acceptors for inverted Schottky junction type rainbow solar cells
(University of Western Cape, 2020)
The main aim of this study was to prepare band gap-engineered graphene quantum dot (GQD) structures which match the different energies of the visible region in the solar spectrum. These band gap-engineered graphene quantum ...
Graphene based materials for carbon capture
(University of Western Cape, 2020)
The adverse effects of CO2 and greenhouse gas emissions into the atmosphere is
believed to be one of the causes of climate change. The seriousness of global warming
is encouraging the development of technologies designed ...
Synthesis and characterisation of sulphonated polyethersulphone membrane materials
(University of Western Cape, 2020)
With current climate change, growing population, and rapid industrialization of developing countries, water is increasingly becoming a scare resource. Within a power plant, processes that consume most water are demineralized ...
The nature of geochemical anomalies associated with the PGE mineralization in the Stella layered intrusion, North West province, South Africa
(University of the Western Cape, 2020)
The redistribution patterns of trace elements related to ore mineralisation in the secondary environment are the foundation of regolith exploration geochemistry. Understanding the controls of these element patterns is ...
Development of capacitive deionisation electrodes: optimization of fabrication methods and composition
(University of the Western Cape, 2020)
Membrane Capacitive Deionisation (MCDI) is a technology used to desalinate water where a potential is applied to an electrode made of carbonaceous materials resulting in ion adsorption. Processes and materials for the ...
Encapsulating of humic acid in hydrogel matrix for the complexation of heavy metals in aqueous solutions
(University of Western Cape, 2020)
Rapid industrialization growth without appropriate emission standards for discharging
environmental pollutants had exposed the ecosystem to detrimental effect. Due to their
bioaccumulation propensity in organisms, toxicity ...
