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 ... -
Nonlinear optical properties of natural dyes based on optical resonance
(University of the Western Cape, 2012)Recent research shows that the study of optical properties of organic material natural dyes has gained much consideration. The specific functional groups in several natural dyes remain essential for the large nonlinear ... -
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 ... -
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 ... -
Thermochromic properties of VO2 nano-coatings by inverted cylindrical magnetron sputtering
(University of the Western Cape, 2012)Vanadium dioxide (VO2) films have been known as the most feasible thermochromic nano-coatings for smart windows which self control the solar radiation and heat transfer for energy saving and comfort in houses and automotives. ... -

Laser drilling of metals and glass using zero-order bessel beams
(University of the Western Cape, 2013)This dissertation consists of two main sections. The first section focuses on generating zero order Bessel beams using axicons. An axicon with an opening angle y = 5⁰ was illuminated with a Gaussian beam of width ω₀ = 1.67 ... -
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 ... -
Magnetic substitution in CePt₂Si₂ and CeCu₅In Kondo lattice
(University of the Western Cape, 2013)In the past few decades, the studies of f-electron materials have revealed unusual physical properties such as Fermi-liquid, non-Fermi-liquid behaviour at low temperatures, heavy- Fermion behaviour, valence fluctuation, ... -
Dynamic variation of hydrogen dilution during hot-wire chemical vapour deposition of silicon thin films
(University of the Western Cape, 2013)This study reports on the effects of hydrogen dilution and deposition time on six silicon thin films deposited at six specific deposition regimes. The thin film properties are investigated via X-Ray diffraction analysis, ... -
Hot-wire chemical vapor deposition of silicon nitride thin films
(2013)Amorphous silicon nitride (a-SiN:H) thin films has a multitude of applications, stemming from the tunability of the material properties. Plasma enhanced chemical vapour deposition (PECVD) is the industrial workhorse for ... -
Teenage mothers’ reflections of their unintended, repeat pregnancies
(2013)Globally, teenage pregnancy remains a disturbing phenomenon which impacts on the lives of teenagers, their families and society as a whole. Numerous attempts at addressing the problem have seen a decline in fertility rates ... -
Optical properties of annealed hydrogenated amorphous silicon nitride (a-SiNx:H) thin films for photovoltaic application
(2013)Technological advancement has created a market for large area electronics such as solar cells and thin film transistors (TFT’s). Such devices now play an important role in modern society. Various types of conducting, ... -
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 ... -
Comparison of neutron fluence spectra measured with NE213 proton recoil spectrometer and NE230 deuteron recoil spectrometer
(University of the Western Cape, 2014)A (5 cm × 5 cm) cylindrical NE213 liquid organic scintillator and a (2.5 cm × 2.5 cm)cylindrical NE230 liquid organic scintillator were used as spectrometers. A series of measurements was made with both the NE213 and NE230 ... -
Growth and characterization of FeSi nanowires by chemical vapor deposition for gas sensing applications
