A study of neutron pairing correlations using the 136Ba(p, t) reaction
(University of Western Cape, 2020)Observation of neutrinoless double beta decay (0 ) is currently the only means by which one could establish the Majorana nature of neutrinos. Additionally, such an observation would determine the absolute neutrino ... -
A study of SiC thin film layers for electrically conductive diffusion barrier application in Si thin film solar cells.
(University of the Western Cape, 2019)Semiconductor silicon carbide (SiC) thin films of different thicknesses were deposited by electron beam physical vapour deposition (EBPVD) for application as diffusion barrier application to guard against metal contaminants ... -
A study of the angular momentum content of early-type galaxies
(University of the Western Cape, 2019) -
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 ... -
Study of the use of Electret Ion chambers as radom dosimeters in South Africa
(University of the Western Cape, 2002)Radon is a naturally occuring radioactive gas which has been shown to be a major contribution to background dose. The underground mines in South Africa present a major occupational hazard. A need for cheap personal monitoring ... -
Studying chirality in a ~ 100, 130 and 190 mass regions
(University of the Western Cape, 2011)Chirality is a nuclear symmetry which is suggested to occur in nuclei when the total angular momentum of the system has an aplanar orientation [Fra97, Fra01]. It can occur for nuclei with triaxial shape, which have valence ... -
Supervised machine learning techniques for radio source classification
(University of the Western Cape, 2023)Classification is one of the most fundamental aspects of scientific investigation. Astronomers have thus developed several classification schemes to try and make sense of the evolving properties of planets, stars and ... -
Synthesis and characterisation of 114Cd targets
(2011)To study nuclear reactions and nuclear structures, target materials are bombarded with high-energy particles. The target material can either be in a form of a metal film or gas. A target material designed to study certain ... -
Synthesis and characterization of Ceria with an optimal oxygen storage capacity as potential medium to remove SO2 from flue gas emissions
(University of Western Cape, 2013)Due to an increasing demand for energy, alternative renewable energy sources are investigated globally. However fossil fuels are still one of the main energy sources. The combustion of these fuels produces by-products such ... -
Synthesis and characterization of ion implanted Pd/Ti/V/Pd/Ti based multilayer thin films using rutherford backscattering spectrometry (rbs) and elastic recoil detection analysis (erda) for hydrogen storage application
(University of the Western Cape, 2022)Hydrogen is regarded as an attractive, pollution-free energy carrier for future energy systems, supported by its efficient energy conversion. Still, the challenge is its storage and transportation. Hydrogen can either ... -
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 ... -
Synthesis of bimetallic immiscible alloy nanoparticles through green and gamma radiolysis approaches for environmental remediation applications
(University of the Western Cape, 2022)The synthesis of bimetallic immiscible alloy nanoparticles (NPs) using versatile routes, is a major concern since physio-chemical methods are not environmentally benign. Breaking down the immiscibility would generate NPs ... -

Synthesis of the metallocenes for the production of exotic high energy ion beams
(University of the Western Cape, 2019)The Subatomic Physics Department of iThemba Laboratory for Accelerated Based Sciences (iThemba LABS) conducts experiments that require a variety of particle beams in order to study nuclear properties (reaction, structure, ... -
Synthesis of zinc oxide nanoparticles by a green process and the investigation of their physical properties
(University of the Western Cape, 2017)Zinc oxide (ZnO) is a wide and direct semiconductor with a wurtzite crystal structure. Its multifunctionality as the ideal candidate in applications such as blue-UV light emitting diodes, transparent conducting oxide, ... -
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 ... -
Test of traditional vibrational wisdom by 2 proton stripping onto targets of 108;110Pd,114Cd,115In
(University of the Western Cape, 2018)The cadmium nuclei have traditionally been regarded as among the best examples of spherical vibrational nuclei. However, advances in nuclear spectroscopy have begun to detail the properties of these nuclei at the two and ... -
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 ... -
Testing gravity with redshift-space distortions, using MeerKAT and the SKA
(University of the Western Cape, 2019)The growth rate of large-scale structure is a key probe of gravity in the accelerating Universe. Standard models of Dark Energy within General Relativity predict essentially the same growth rate, whereas Modified Gravity ... -
Testing the statistical isotropy of the universe using radio survey data
(University of the Western Cape, 2019)The Cosmological Principle forms part of one of the most fundamental hypotheses of modern Cosmology. So it is very important to assess whether it holds true using observational data, or whether it consists of a mathematical ...
