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 ...
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 ...
The synthesis of Ventiloquinones J and F
(University of Western Cape, 2002)
In chapter 2 the synthesis of ventiloquinone J is described, starting from vanillin, the key intermediate cis-3,4-dihydro-5,7-dimethoxy-10-
methoxymethyleneoxy-1,3-dimethyl-1H-naphtho[2.3-c]pyran-6,9-dione was prepared ...
Thiolato schiff base complexes of nickel and palladium as mesogens and molecular wires
(University of the Western Cape, 2003)
Thermal analysis data of compounds A, C, F and I established that they were nonmesogenic
while E and G were found to be mesogenic. The lack of mesogenic behaviour
of A could be attributed to hydrogen bonding. The ...
Palladium surface-modified rare earth metal-based ab5 type hydride-forming materials
(University of the Western Cape, 2008)
Driven by mounting standards of living and a growing population, South African energy consumption is expected to increase dramatically within the next decade. The increased demand for more energy will require enormous ...
Quantum dots for multiplexed biological imaging
(University of the Western Cape, 2023)
Over the past two decades, indium phosphide (InP) colloidal quantum dots (QDs) have attracted substantial interest as a possibly less hazardous alternative to cadmium-based QDs. The improvements in their colloidal synthesis ...
Investigation of ternary catalysts as anode catalysts for direct methanol fuel cell
(University of the Western Cape, 2023)
This chapter reports on various catalyst synthesis methods (impregnation, polyol, modified polyol and microwave-assisted modified polyol methods) to determine which method would result in the most electrochemically active ...
Spectroelectrochemical determination of the antioxidant properties of carpobrotus mellei and carpobrotus quadrifidus natural products
(University of the Western Cape, 2009)
South African Carpobrotus species have been found to contain hydrolysable tannins, various tlavonoids e.g. rutin and hyperoside, phytosterols and aromatic acids which have a diverse range of pharmacological properties ...
Electrochemical responses of novel preferentially oriented platinum (100) nanoalloys for ammonia and hydrazine catalysis
(University of the Western Cape, 2013)
Ammonia has attracted attention as a possible fuel for direct fuel cells since it is easy to handle under low pressure, costs only slightly higher than methanol and can easily be cracked down into hydrogen and nitrogen. ...
