Transport and thermodynamic properties of rare earth compounds and alloys
(University of the Western Cape, 2017)
Rare-earth (RE) elements possess an incompletely lled 4f shell, which is very small compared
to typical interatomic distances. As a result of this, RE elements and compounds
exhibit characteristic properties, which deviate ...
Cosmology with next generation radio telescopes
(University of the Western Cape, 2019)
The next generation of radio telescopes will revolutionize cosmology by
providing large three-dimensional surveys of the universe. This work presents
forecasts using the technique 21cm intensity mapping (IM) combined ...
High resolution gamma-spectroscopy of environmental samples
(University of the Western Cape, 2019)
In this study, a comparison has been made between the available commercial software package
Genie 2000 developed by Canberra and Virtual Gamma Spectroscopy Laboratory (VGSL)
developed by the Radionuclide Development Unit ...
Detecting Baryon Acoustic Oscillations with HI Intensity Mapping using MeerKAT
(University of the Western Cape, 2019)
Future radio surveys as the Square Kilometer Array (SKA) and its precursor, the "Meer"
Karoo Array Telescope (MeerKAT), will map the Neutral Hydrogen (HI) in large areas of
the sky using the intensity mapping (IM). HI ...
Computational modelling of a hot-wire chemical vapour deposition reactor chamber
(University of Western Cape, 2020)
In this thesis, I explore the subjects of fluid dynamics and the Hot-Wire Chemical Vapour
Deposition (HWCVD) process. HWCVD, in its simplicity, is one of the more powerful and
elegant deposition techniques available in ...
Study of magnetic properties of nanostructures on self-assembled patterns
(University of the Western Cape, 2010)
In the current study, we give a report when oxalic acid was used as an electrolyte to synthesize an AAO template with hexagonal pore array. Optimum parameters were observed as 0.4 M of oxalic acid, anodizing voltage of 45 ...
Three dimensional thermal modelling of high temperature proton exchange membrane fuel cells in a serpentine design
(University of the Western Cape, 2010)
The aim of my work is to model a segment of a unit cell of a fuel cell stack using numerical methods which is classified as computational fluid dynamics and implementing the work in a commercial computational fluid dynamics ...
Structure property relationship and thermal stability of organic photovoltaic cells
(University of the Western Cape, 2010)
In this thesis, regioregularpoly( 3-hexylthiophene) (rr-P3HT) polymer was used as a light absorption and electron donating material, while the C60 fullerene and its derivative [6,6]-phenyl C61-butyric acid methyl ester ...
Determination of the photopeak detection efficiency of a HPGe detector, for volume sources, via Monte Carlo simulations
(University of the Western Cape, 2005)
The Environmental Radioactivity Laboratory (ERL) at iThemba LABS undertakes experimental work using a high purity germanium (HPGe) detector for laboratory measurements. In this study the Monte Carlo transport code, MCNPX, ...
A theoretical study of stellart pulsations in young brown dwarfs
(University of the Western Cape, 2011)
This thesis reports the results of a twofold study on the recently proposed phenomenon of ‘stellar pulsations’ in young brown dwarfs by the seminal study of Palla and Baraffe (2005) (PB05, thereafter). The PB05 study ...
