Characterisation of natural radioactivity in Karoo Basin groundwater prior to shale gas exploration
(University of the Western Cape, 2017)
The prospect of unconventional shale-gas development in the Karoo Basin (South Africa) has created
the need to obtain baseline data on natural radioactivity in Karoo groundwaters. The Karoo Basin
groundwater radiological ...
Plasma characterisation of an electron cyclotron resonance ion source by means of x-ray spectroscopy
(University of the Western Cape, 2012)
The ultimate aim of any multiply-charged ion source, like the Electron Cyclotron Resonance Ion Source, ECRIS, is the production of multiply-charged ions, in sufficiently large quantities. These multiplycharged ions, in the ...
The design and simulation of a new experimental set up to measure nuclear level lifetimes
(University of the Western Cape, 2016)
Measurements of nuclear level lifetimes are an important aspect of experimental nuclear physics. Such measurements determine transition matrix elements for nuclear structure research and also provide the widths of relevant ...
The curious case of offset bars : markers for a baby galaxy disk or signposts of an interaction with dark matter sub halos?
(University of the Western Cape, 2016)
We have used the Spitzer Survey of Stellar Structure in Galaxies (S⁴G) as a representative sample of the local universe (total of 2352 galaxies in S⁴G) to make a catalog of offset disk barred galaxies. Using the combined ...
Growth and characterization of FeSi nanowires by chemical vapor deposition for gas sensing applications
(University of the Western Cape, 2014)
FeSi nanowires were synthesized via a chemical vapor deposition method. Anhydrous FeCl3 powder in this case served as the Fe source and was evaporated at a temperature of 1100oC to interact with silicon substrates which ...
Effect of the additional electron acceptor in hybrid ZnO: P3HT:PCBM spin-coated films for photovoltaic application
(University of the Western Cape, 2015)
In a quest for low operational and maintenance cost solar cell devices, organic photovoltaics remain a potential source of energy worthy to be explored. In order to generate cost- effective electricity from solar energy, ...
Deposition of silicon nanostructures by thermal chemical vapour deposition
(University of the Western Cape, 2015)
In this thesis we report on the deposition of silicon nanostructures using a 3-zone thermal chemical vapour deposition process at atmospheric pressure. Nickel and gold thin films, deposited by DC sputtering on crystalline ...
An Investigation of magnetic storm effects on total electron content over South Africa for selected periods in solar cycles 23 and 24
(University of the Western Cape, 2012)
The development of regional ionospheric Total Electron Content (TEC) models has contributed to understanding the behavior of ionospheric parameters and the coupling of the ionosphere to space weather activities on both ...
Hydrogenisation of metals
(University of the Western Cape, 2013)
Transition metals are a group of metals which are light in weight and have high hydrogen solubility. Their interaction with hydrogen is exorthermic and this phenomenon makes them “ideal” candidates for various applications ...
Deposition and structural properties of silicon carbide thin films for solar cell applications.
(University of the Western Cape, 2014)
The growth of hydrogenated amorphous silicon carbide (a-SiC:H) thin films deposited by Hot- Wire Chemical Vapour Deposition (HWCVD) for solar cell applications has been studied. The films were characterized for structural ...
