A comparative energy storage efficiency study of multiple cation doped LiMxMn2-xO4/MWCNT cathodes for advanced Li-ion batteries
(University of the Western Cape, 2022)The current lithium-ion battery which is used in most technological applications is the LiCoO2 (LCO) battery. This battery offers a high theoretical capacity of 274 mAh.g-1. Scientists have however deemed this battery ... -
Dehydrogenation of alkanes using sulfided metal catalysts
(University of Western Cape, 2021)Light olefins are some of the main raw materials for the petrochemical industry. With the rise in oil prices and increasing demand for olefins, there is an increasing interest in finding cheaper alternatives for processes ... -
Effluent water treatment utilising a combination of hydrodynamic shear and flotation technology for the specific application of wastewater from the oil and gas industry
(University of the Western Cape, 2022)Water plays an important role in the petrochemical production and refining processes. The wastewaters released by these processes are often rich in petroleum pollutants, that requires significant treatment prior to ... -
Green synthesis of novel nanostructured silicon semiconductor thin film material from sugarcane bagasse ash for solar energy materials
(University of the Western Cape, 2022)The sun is considered the most abundant source of renewable and clean energy. With silicon being the most common element used for the direct conversion of solar energy into electrical energy, solar cells have, over the ... -
Identification, separation and quantification of persistent organic pollutants using capillary electrophoresis
(University of the Western Cape, 2022)Water quality deterioration and scarcity can be attributed to natural causes and anthropogenic activities which include climate change and an incessant industrialisation, yet with lack of functional and reliable wastewater ... -
Modification of nanostructured carbon based supports for direct methanol fuel cells
(University of the Western Cape, 2022)Palladium (Pd) and Palladium-Ruthenium (Pd-Ru) nanoparticles supported by various carbon nanomaterials which include graphene oxide (GO), reduced graphene oxide (rGO) and multiwalled carbon nanotubes (MWCNTs) with their ... -
Synthesis of new biguanide derivatives as potential antidiabetic drugs
(University of the Western Cape, 2022)The main purpose of this study was to synthesize biguanide compounds with potential as antidiabetic drugs. All biguanide compounds possess antidiabetic properties by decreasing the blood glucose level. Hence, we embarked ...
