Computer simulation studies of a few representative Platinum-Group- Minerals (PGM), which are of industrial importance to the mining industry in South Africa were carried out. The electronic, structural and optical ...

Since the rechargeable battery performance involving TiO2 anode strongly depends on its structural, transport and electrochemical properties, it is important to explore different TiO2 nanostructures in order to improve its ...

The dissertation describes the use of 2-benzenesulfonyloxyquinoxaline as a good coupling partner for different amine substrates. The palladium-mediated cross- coupling of aryl electrophiles and amines has become a widely ...

In this study, antioxidant activity methodologies were evaluated in terms of analytical performances. The total antioxidant activity from Athrixia phylicoides leaves (Bush tea) determined using 2,2-diphenyl-1-picrylhydrazyl ...

Bilayer graphene and single-walled carbon nanotubes were studied through classical molecular dynamics using Tersoff potential. The Tersoff potential has been the most successful model to replicate much of the semiconducting ...

Beyond conventional intercalation chemistry, reaction of lithium with sulphur and oxygen (so-called “Li-air” batteries) have the potential to provide 2 to 5 times the energy density of current Li-ion battery systems. ...

The aim of the project was to synthesize quinoline-1,2,3-triazole Schiff base hybrids as promising anti-cancer agents. A laboratory prepared 2-Amino-3,5dibromoactophenone was subjected to Claisen-Schmidt aldol-condensation ...

Breast cancer is a malignant tumour that starts in the cells of the breast. Many studies revealed aromatase (CYP19A1) and cyclin-dependent kinase 2 (CDK2) as possible therapeutic targets regarding breast cancer treatment, ...

Surveys indicate that most South African origin women want long and straight hair (Mamabolo and Summers, 2006). Such women will therefore use a relaxer to straighten their hair. Many such preparations cause damage to the ...

The structural and energetic properties of the Ti-Al and Pt-Ti alloys have been carried out using first-principles total energy calculation of the density functional theory. We found a good correlation between VASP and ...
