Coulomb excitation of 66ge
(University of Western Cape, 2021)The Coulomb excitation of 66Ge has been performed for the rst time using \safe" bombarding energies at the HIE-ISOLDE facility at CERN in July 2017. A particle- coincidence experiment using the MINIBALL array and ... -
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 ... -
Structural and physical properties of ReN i03 (Re=Sm, N d) nanostructured films prepared by Pulsed Laser Deposition
(University of the Western Cape, 2010)Very few systems allow the study of the relationship between structural changes and physical properties in such a clear way as rare earth nickelate ReNi03 perovskites (Re (rare earth) = Pr, Nd, Sm and Gd). Synthesized for ... -
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 ... -
Development and study of a Thoron (Rn-220) standard source
(University of Western Cape, 2019)Thoron Rn-220 is a radioactive gas with a half-life of 55.6 s. It has been identified as a possible health concern in specific places such as monazite processing plants and (rare-earth) mines. The short half-life of Rn-220 ... -
Probing galaxy evolution below the noise threshold with radio observations
(University of the Western Cape, 2020)The faint radio population consisting of star forming galaxies (SFG) and radio-quiet active galactic nuclei (AGN) is important in the study of galaxy evolution. However, the bulk of the faint population is below the ... -
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 ... -
Variability and interannual trends in the climatology of radon-222 at two Southern Hemisphere coastal baseline sites
(University of the Western Cape, 2021)This thesis characterises and discusses two continuous coastal Southern Hemispheric (SH) atmospheric radon (222Rn) signals. Large-scale atmospheric circulation patterns are important components of the climate system ... -
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 ... -
Application of vertically aligned arrays of metal-oxide nanowires in heterojunction photovoltaics
(University of the Western Cape, 2020)The commercial need to improve the performance of low-cost organic solar cells has led to the idea for this research. The study discusses the synthesis of one dimensional TiO2 and ZnO nanowire arrays synthesised using a ... -
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 ...
