Preparation and characterization of highly active nano pt/c electrocatalyst for proton exchange membrane fuel cell
(University of the Western Cape, 2006)
Catalysts play an essential role in nearly every chemical production process. Platinum supported on high surface area carbon substrates (Pt/C) is one of the promising candidates as an electrocatalyst in low temperature ...
Electrochemical impedance modelling of the reactivities of dendrimeric poly(propylene imine) DNA nanobiosensors
(University of the Western Cape, 2008)
In this thesis, I present the electrochemical studies of three dendrimeric polypropylene imine (PPI) nanomaterials and their applications as a platform in the development of a novel label free DNA nanobiosensor based on ...
The Synthesis of Biaxial Naphthoquinones and an Initial Investigation regarding their Potential as anti- Mycobacterium tuberculosis and Apoptotic Agents
(University of the Western Cape, 2009)
Tuberculosis and cancer are amongst the most devastating diseases affecting the world today, especially Africa and other less developed countries. Both diseases have the ability to develop resistance against drugs being ...
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 ...
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 ...
