Silver-coated polyethene terephthalate membrane for detection of pharmaceuticals using surface-enhanced Raman spectroscopy
(University of the Western Cape, 2017)Surface-enhanced Raman spectroscopy (SERS) has emerged as one of the analytical tools for detection of micro pollutants in the aquatic environment. The SERS technique is touted to have fingerprinting capability, specificity, ... -
Development of capacitive deionisation electrodes: optimization of fabrication methods and composition
(University of the Western Cape, 2017)The objective of this research was to optimize the fabrication methods for and compositions of electrodes for the Membrane Capacitive Deionisation (MCDI) system. Two electrode fabrication methods were developed, namely a ... -
Carbon supported aluminium trifluoride nanoparticles functionalized lithium manganese oxide for the development of advanced lithium ion battery system
(University of the Western Cape, 2017)A novel lithium ion (Li-ion) battery cathode material has been investigated for potential mobile technology energy storage applications. I have successfully synthesized Lithium Manganese oxide (LMO), reduced Graphene Oxide ... -
Synthesis of metal modified Mesoporous Zeolites catalysts: application in conversion of Olefins to Valuable liquid products
(University of the Western Cape, 2016)The effects of temperature, synthesis duration and silica source were studied to obtain suitable conditions for our laboratory experiment concerned with the synthesis of MCM-41 catalyst. The transformation of 1-hexene was ... -
Graphenated electrode protocol for electrochemical nanosensing of 17β- estradiol as an environmental estrogeneous endocrine disruptor
(University of the Western Cape, 2016)17β-Estradiol can be defined as an endocrine disruptor chemical with estrogenic activity, which can bind to the estrogen receptor in the body and potentially alter the normal physiological function of the endocrine ... -
Functionalisation of polymer nanofibres and track-etched membrane removal of organic and and inorganic pollutants from water
(University of the Western Cape, 2017)Organic and inorganic pollutants are two broad classes of pollutants in the environment with their main sources from waste waters that are indiscriminately dumped from chemical related industries. Among the organic ... -
Porous metal complexes for CO2 capturing
(University of the Western Cape, 2017)The need in energy has resulted in the burning of fossil fuels at an increasingly high level. The consequence is a release of high volumes of carbon dioxide gas (CO2) in the atmosphere. This gas is a major greenhouse gas ... -
Detection of selective Tyrosinase inhibitors from some South African plant extracts of Lamiaceae family
(University of the Western Cape, 2016)Various dermatological disorders, such as formation of black pigmented patches on the surface of the skin arise from the over-activity of tyrosinase enzyme's degenerative action. This enzyme is further implicated in the ... -
Fabrication of luminescent nanocomposites for diagnosis of breast cancer
(University of the Western Cape, 2016)In this study we were able to synthesize separately iron oxide magnetic nanoparticles, InP/ZnSe and CdTe/ZnS quantum dots. The iron oxide nanoparticles were coupled with InP/ZnSe QDs to form the luminescent magnetic ... -
Synthesis, characterization, and molecular docking of novel 4-Aminoquinolines and Salicylaldimine complexes: evaluation as antimalarial and antitumor agents
(University of the Western Cape, 2016)Malaria remains a major global health problem and to date, hundreds of thousands of people die as a result of this disease every year. Malaria has been able to adapt and rebound despite various efforts made to combat the ... -
Electrospinning of porous composite materials for hydrogen storage application
(University of the Western Cape, 2016)Due to the rapid depletion of fossil fuel reserves and the production of environmentally harmful by-products such as carbon dioxide, there is an urgent need for alternate sustainable clean energy. One of the leading ... -
Recovery of SiO₂ and Al₂O₃ from coal fly ash
(University of the Western Cape, 2016)Most of the world's energy production is still mainly achieved by the combustion of coal in power stations. Coal fly ash is the inevitable waste product that accumulates to metric ton volumes each year. These vast volumes ... -
Microfluidic graphenised-paper electroanalytical devices (μGPED) for adsorptive cathodic stripping voltammetric detection of metal contaminants
(University of the Western Cape, 2017)The need for clean, non-toxic drinking water supplies, free of pollutants and metal contamination is vital in impoverished areas and the developing world alike. With this in mind, the development of accurate, inexpensive, ... -
Electrochemical poly(ProDOT) dendritic DNA aptamer biosensor for signalling interferon gamma (IFN-ɣ) TB biomarker
(University of the Western Cape, 2017)Tuberculosis (TB) is an infectious disease that, despite all efforts devoted towards its eradication, remains a threat to many countries including South Africa. Current diagnostic assays do offer better performance than ... -
Development of Schiff base electrochemical sensors for the evaluation of polycyclic aromatic hydrocarbons in aqueous medium
(University of the Western Cape, 2017)A novel monomer (N,N'-Bis-(1H-pyrrol-2-ylmethylene)-benzene-1,2-diamine-BPPD) was derived from the condensation reaction between o-phenylenediamine and a pyrrole derivative. The monomer was polymerized electrochemically ... -
Quantum dots-amplified electrochemical cytochrome P450 phenotype sensor for tamoxifen, a breast cancer drug
(University of the Western Cape, 2017)Breast cancer is regarded as the most common cancer in South Africa and its rate of occurrence is increasing. About one in every 31 South African women are at the risk of developing breast cancer and early diagnosis and ... -
The development of graphene oxide sheet- and polyanilino-immunosensor systems for lipoarabinomannan (LAM) tuberculosis biomarker
(University of the Western Cape, 2017)Tuberculosis (TB) is an infectious disease with adverse effect on a global scale. The disease is one of the major causes of death in sub-Saharan Africa. Nearly 70% of TB-infected persons are co-infected by the human ... -
Electrochemical in-situ polymerization of graphene oxide/conducting star copolymer nanocomposite as supercapacitor electrode
(University of the Western Cape, 2017)These days there are deep concerns over the environmental consequences of the rate of consumption of energy from non-renewable sources because of the accelerated increase in greenhouse effect. There is, therefore, increasing ... -
