Tin-oxide thin films by thermal oxidation
(University of Western Cape, 2021)Tin dioxide (SnO2) thin films are a worthy candidate for an electron transport layer (ETL) in perovskite solar cells, due to its suitable energy level, high electron mobility of 240 cm2 v-1 s- 1, desirable band gap of ... -
An investigation into the morphology of radio sources
(University of Western Cape, 2021)Radio galaxies are some of the most unusual and powerful objects in the Universe and are therefore vital for so many reasons. Studies of Radio-Loud Active Galactic Nuclei (AGN) gives us the potential to enhance our ... -
A relativistic analysis of proton-induced knockout reactions from oxygen isotopes with direct and inverse kinematics.
(University of the Western Cape, 2020)In this study a complete set of exclusive (~p; 2p) polarization transfer observables of closed-shell oxygen isotopes are calculated using both direct and inverse kinematics using the relativistic plane wave impulse app ... -
Nitrogen and argon treatment of titanium dioxide nanowire arrays
(University of Western Cape, 2021)TiO2 nanoparticle films are important electron transport layers (ETLs) in photovoltaics such as dye-sensitised, perovskite and polymer hetero-junction solar cells. These films, however, have significant electron trap-sites ... -
Latent and thermal energy storage enhancement of silver nanowires-nitrate molten salt for concentrated solar power
(University of Western Cape, 2020)Phase change material (PCM) through latent heat of molten salt, is a convincing way for thermal energy storage in CSP applications due to its high volume density. Molten salt, with (60% NaNO3 and 40% KNO3) has been used ... -
Neutral hydrogen intensity mapping on small scales using MeerKAT
(University of the Western Cape, 2021)In the post-reionisation universe, intensity mapping (IM) with the 21 cm line of neutral hydrogen (HI) provides a potential means of probing the large-scale structure of the universe. With such a probe, a wide variety of ... -
Photo-physical properties of lead-tin binary Perovskite thin films
(University of Western Cape, 2021)Organic-inorganic lead-based perovskite has exhibited great performance in the past few years. However, the lead (Pb) embedded in those compounds is a significant drawback to further progress, due to its environmental ... -

Giant Magnetocaloric effect and Magnetic Properties of selected Rare-Earth compounds
(University of the Western Cape, 2021)Rare-earth (RE) compounds have been an attractive subject, based on the unique electronic structures of the rare-earth elements. In particular, the RETX (RE = rare-earth, T = 3d/4d/5d, transition metals, and X = p – block ... -
A multi-scale study of the star formation law in nearby galaxies
(University of the Western Cape, 2020)This research aimed to evaluate the effects of changing length-scales on the star formation laws and star formation efficiencies for our selected sample of galaxies. We have combined high-resolution Hi data from The Hi ... -
Gas sensing properties of Ceo2 nanostructures
(University of the Western Cape, 2020)The industrial safety requirements and environmental pollution have created a high demand to develop gas sensors to monitor combustible and toxic gases. As per specifications of World Health Organization (WHO) and Occupational ... -
Testing Gravity with MeerKAT and the SKA
(University of the Western Cape, 2020)The new 64-dish radio telescope array MeerKAT will be absorbed into the international Square Kilometre Array (SKA) in late 2020s. These two telescope arrays will produce three-dimensional maps of the integrated intensity ... -
Carbon, magnesium implantation and proton irradiation on pulsed laser deposited thermochromic thin film of VO2
(University of Western Cape, 2020)When the spacecrafts orbit in space, it is subjected to significant thermal cycling variation. Thermal regulation of the spacecraft temperature is required to ensure a good operation of the small crafts such as CubeSats ... -
A study of the nearby interacting galaxy pair NGC 1512/1510
(University of Western Cape, 2020)This work focuses on generating a new dynamical model of the nearby (9.5 Mpc) interacting galaxy system NGC 1512/1510. Neutral hydrogen (H i ) observations from the Australia Telescope Compact Array (ATCA) are used to ... -
Hydrogen storage capacity of the Ti-Pd multilayer systems
(University of the Western Cape, 2020)Hydrogen has high energy density and it is regarded as the future energy carrier. Hydrogen can be stored as a gas in high-pressure cylinders, as a liquid in cryogenic tanks and as a solid in metal hydrides. The storage of ... -
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 ... -
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 ... -
Mock HI spectral line stacking experiments for large galaxy surveys
(University of Western Cape, 2019)The study of neutral atomic hydrogen (HI) plays a vital role in improving the knowledge about galaxy evolution since HI serves as the raw fuel for star formation. However, the current knowledge about it is limited to the ... -
Modelling and measurement of radon diffusion through soil application on mine tailings dams.
(University of Western Cape, 2004)Radon (222Rn) has been identified as an important factor that could result in a health hazard by studies all around the world. The health risks can be minimised by preventive measures where radon is highly concentrated as ... -
