The effects of capping agents on the synthesis of magnetic-luminescent Fe₃O₄ -InP/ZnSe nanocomposite material
(University of the Western Cape, 2015)
Magnetic luminescent nanoparticles of an iron oxide (Fe₃O₄) superparamagnetic core and an indium phosphide/zinc selenide (InP/ZnSe) quantum dot shell are reported. The magnetic nanoparticles (MNP’s) and quantum dots (QD’s) ...
Durability studies of membrane electrode assemblies for high temperature polymer electrolyte membrane fuel cells
(University of the Western Cape, 2011)
Polymer electrolyte membrane fuel cells (PEMFCs) among other fuel cells are considered the best candidate for commercialization of portable and transportation applications because of their high energy conversion and low ...
Photocatalytic degradation of organic pollutants using Ag-Fe₃O₄/SiO₂/TiO₂ nanocomposite
(University of the Western Cape, 2015)
The global lack of clean water for human sanitation and other purposes has become an emerging dilemma for human beings. The presence of organic pollutants in wastewater produced by textile industries, leather manufacturing ...
Synthesis of ZSM-5 zeolite from South African fly ash and its application as solid catalyst
(University of the Western cape, 2016)
Zeolites are widely used as environmentally friendly solid catalysts or catalyst supports in the refining and petrochemical industries. ZSM-5 zeolite is composed of a three-dimensional medium pore structure (openings of ...
Advanced Ti – based AB and AB2 hydride forming materials
(University of the Western Cape, 2011)
Ti – based AB and AB₂ hydride forming materials have shown to be very promising hydrogen storage alloys due to their reasonable reversible hydrogen storage capacity at near ambient conditions, abundance and low cost. ...
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 ...
Designing next generation high energy density lithium-ion battery with manganese orthosilicate-capped alumina nanofilm
(University of the Western Cape, 2015)
In the wide search for advanced materials for next generation lithium-ion batteries, lithium manganese orthosilicate, Li₂MnSiO₄ is increasingly gaining attention as a potential cathode material by virtue of its ability to ...
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, ...
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 ...
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 ...
