(University of the Western Cape, 2022)With the rapid rise in energy demand and ever-escalating environmental hazards, the need for transition from fossil fuel to renewable energy sources is of paramount importance, requiring better and efficient energy storage ... -
Hydrothermal conversion of agricultural and food waste
(University of Western Cape, 2022)The global dependence on non-renewable fossil fuels to meet energy needs cannot be sustained for a long time and it is already evident in the escalation of fuel prices over the past decade. This research was performed ... -
Polydopamine coated platinum catalysts to improve fuel cells durability
(University of Western Cape, 2022)Polymer electrolyte membrane fuel cells (PEMFC) are in the forefront of energy production and have drawn a great deal of attention in both fundamental and application in recent years. It is a promising energy system used ... -
Hydrogen generation by hydrolysis of magnesium and aluminium alloys and their hydrides
(University of the Western Cape, 2021)This study presents the successful characterization and hydrolysis of magnesium hydride (MgH2) for hydrogen generation. The as-received MgH2 served as a precursor in most of the hydrolysis experiments for H2 generation. ... -
Secondary metabolites of the uromycladium tepperianum macalpine epiphytic fungus
(University of the Western Cape, 2021)Research on natural products and medicinal plants has been conducted more with each passing year due to the great interest in isolating bioactive compounds and secondary metabolites from natural products such as plants, ... -
Polypyrrole supports for direct alcohol fuel cells.
(University of Western Cape, 2021)Anode catalysts are one of the key components of direct alcohol fuel cells (DAFCs). They play a huge role in the alcohol oxidation reaction (AOR) that occurs on the anode side. Palladium (Pd) supported on carbon material ... -
The role of surface modified TiO2 nanoparticles for application in 68Ge/68Ga generator systems and the use of molecular imprinted polymers for 68Ge breakthrough control
(University of Western Cape, 2021)Titanium dioxide (TiO2) has potential as an adsorbent within the 68Ge/68Ga generator context. To function effectively, three basic requirements are required: optimum 68Ga elution efficiency, stability and removal of the ... -
Isothermal and non-isothermal comparative study of Zn-sn system using real-time RBS
(2021)Solid-state reactions of bi-metallic systems can be driven or activated by various external stimuli like pressure, energetic photons, energetic charged particles or heat. For an example, high pressure torsion can be ... -
Extraction, fractionation, nanoparticles formulation, and antimicrobial activity of lipids from black soldier fly larvae
(University of Western Cape, 2021)Hermetia illucens (Diptera: Stratiomyidae) known as the black soldier fly (BSF) is an efficient ecological organic waste decomposer. Its larvae grow through six larval instars on a variety of decomposing organic substrates ... -
Active neutralisation and amelioration of acid mine drainage with fly ash
(University of the Western Cape, 2009)Due to the constraints being placed on water resources and a drive for major industries to recycle waste water, improved and cheaper water treatment technologies are being investigated. During mining, pyrite (FeS2), a ... -
Treatment of brines using commercial zeolites and zeolites synthesized from fly ash derivative
(University of the Western Cape, 2008)South Africa is one of the countries that have scarce natural resources that they have to preserve what is available at their disposal. South Africa is also fast becoming one of the countries with major industrial development. ... -
Method development for selective recovery of rare earths elements from phosphogypsum waste
(University of Western Cape, 2021)The need for rare earth elements (REEs) in current technologies has motivated countries with high imports dependency to search for alternatives sources. Several studies have been carried out to investigate the feasibility ... -
