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 ...
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 ...
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 ...
Determination of the Spectroscopic Quadrupole moment of the first 2+ excited state in 32S
(University of the Western Cape, 2019)
In this work we have determined the spectroscopic or static quadrupole moment
of the rst excited state (QS (2+1) lying at 2230.6 keV in 32S using the reorientation
e ect. The Coulomb-excitation experiment at safe ...
Synthesis and characterization of silver nanoparticles for photovoltaic application
(2013)
With an increase in the amount of harmful carbon emissions in the atmosphere as well as a decrease in the availability of fossil fuels, there is a relatively high demand for alternate energy devices. Solar cells have become ...
Macroscopic and Microscopic surface features of Hydrogenated silicon thin films
(University of the Western Cape, 2018)
An increasing energy demand and growing environmental concerns regarding the use of fossil
fuels in South Africa has led to the challenge to explore cheap, alternative sources of energy.
The generation of electricity from ...
