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 ...
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 ...
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 ...
Synthesis and characterization of Ceria with an optimal oxygen storage capacity as potential medium to remove SO2 from flue gas emissions
(University of Western Cape, 2013)
Due to an increasing demand for energy, alternative renewable energy sources are investigated globally. However fossil fuels are still one of the main energy sources. The combustion of these fuels produces by-products such ...
Studying chirality in a ~ 100, 130 and 190 mass regions
(University of the Western Cape, 2011)
Chirality is a nuclear symmetry which is suggested to occur in nuclei when the total angular momentum of the system has an aplanar orientation [Fra97, Fra01]. It can occur for nuclei with triaxial shape, which have valence ...
Metal oxide nanocrystalline thin films as buffer layers in organic/ hybrid solar cells
(University of Western Cape, 2019)
Without reverting to encapsulation, organic bulk - heterojunction solar cells
can be protected from the oxidation of the highly reactive low work function
cathode metal electrode, by the deposition of metal oxide buffer ...
Measuring the quasar luminosity function below the detection threshold
(University of the Western Cape, 2016)
The radio emission of radio-quiet active galactic nuclei (AGN) is thought to be from star formation and AGN related emission. I investigate these sources using 1.4 GHz radio data from FIRST and three optical quasars samples ...
