(University of Limpopo (Turfloop Campus), 2004)This thesis explores the important issues associated with the insertion of Mg2+ and Li+ into the solid materials: molybdenum sulphide and titanium disulphide. This process, which is also known as intercalation, is driven ...
-
(2005)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 ...
-
Ab initio study of cohesive, electronic and elastic properties of ordered cubic-based Mg-Li alloys (University of Limpopo (Turfloop Campus), 2005)Self-consistent electronic structure calculations have been performed on ordered cubic-based magnesium-lithium (Mgx-Li1−x) alloys spanning the concentration range 0 ≤ x ≤ 1, using an ab initio plane wave pseudopotential ...
-
(University of Limpopo (Turfloop Campus), 2005)We have derived a potential model for °uorapatite Ca10(PO4)6F2, ¯tted to structure, elastic constants and vibrational frequencies of the phosphate groups, which is compatible with existing calcite and °uorite potential ...
-
(2005)Electrolytic Manganese Dioxide (EMD) is an important material for manufacturing alkaline electrolyte in commercial batteries. The structure of this material, which tends to be an intergrowth of pyrolusite and ramsdellite ...
-
(2006)The structural, electronic and optical properties of titanium dioxide (TiO2) in anatase phase have been studied by first-principle self-consistent local density approximation. Norm-conserving pseudopotentials were utilized ...
-
(University of Limpopo (Turfloop Campus), 2007)Molecular dynamics simulations have been carried out in order to examine the mechanism of diffusion of molecules in amorphous polymer matrix. PDMS model was folded in to a periodic cell, generated by rotational isomeric ...
-
(2007)The aim of this thesis is to study the structure and reactivity of FeS2 (pyrite).The transition metal sulphide, FeS2 crystallizes into cubic (pyrite) and orthorhombic (marcasite), is an important member of the sulphides ...
-
(2009)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 ...
-
(2009)Calculations were carried out on transition-metal sulphides (TMS) and transitionmetal arsenides (TMA), in both pyrite- and marcasite-type structures, using planewave (PW) pseudopotential methods within density functional ...
-
(University of Limpopo (Medunsa Campus), 2009)Magnetic nanoparticles have been proposed for use as biomedical purposes to a large extent for several years. In recent years, nanotechnology has developed to a stage that makes it possible to produce, characterize and ...
-
(University of Limpopo (Medunsa Campus), 2009)Rhus leptodictya is a member of the Anacardiaceae (mango family) and is used for treating bacteria related disease by indigenous cultures in South Africa. Domestic animals feed on the tree during times of drought and ...
-
(University of Limpopo (Medunsa Campus), 2010)Key words: Monte Carlo simulation, MCNP5 code, Beta irradiation, Teflon-encased eye applicator, Dosimetry, Strontium-90 (Sr-90) Introduction: The treatment of various superficial lesions of the eye and skin has been conducted ...
-
(University of Limpopo (Medunsa Campus), 2010., 2010)Key words: Diagnostic reference levels (DRL), entrance surface dose (ESD), thermoluminescence dosimetry (TLD) Introduction: Diagnostic reference levels (DRL‟s) are defined as a dose level set for standard sized patients ...

(University of Limpopo (Medunsa Campus), 2010)Summary not available
-
(University of Limpopo (Medunsa Campus), 2011)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 ...
-
(University of Limpopo (Turfloop Campus), 2011)Planewave pseudopotential calculations were conducted to predict the energetics and phase stability of Pt-Cr and Ru-Cr binary alloys. Validation of appropriate number of k-points and planewave energy cut-off was carried out ...
-
(University of Limpopo (Medunsa Campus), 2011)Isolation and characterization of antibacterial and antioxidant compounds present in Combretum collinum Sub specie Suluense Leaf extracts of six different plants, many of which are used by traditional healers, were ...
-
(University of Limpopo (Turfloop Campus), 2011)The importance of gold for scientific uses is of fundamental importance to research and technology developments. The bulk gold shows reluctance to participate in chemical reactions, the effect which has been corrected by ...
