Structural features of air-processible methyl ammonium lead triiodide (MAPbI3) perovskite thin films grown on Al-doped ZnO Nanowire Arrays
(University of the Western Cape, 2023)The performance of air stable, mixed halide (MAPbI3-xClx) perovskite based solar cells is highly dependent on the quality and stability of the perovskite thin film, which in turn, is dependent on the substrate on which it ... -
Accelerating reionization simulations using machine learning
(University of the Western Cape, 2023)Epoch of Reionization (EoR) refers to the time in the history of the universe when the appearance of the first luminous sources reionized the intergalactic medium (IGM). The EoR carries a wealth of information regarding ... -
Machine learning approaches to study star formation and black hole accretion in the Meerkat/MIGHTEE survey
(University of the Western Cape, 2023)Galaxy formation and evolution are driven by two main physical processes: star formation and black hole accretion. Both processes can be traced via the synchrotron emission at radio wavelengths. However, a reliable ... -
Inclusive (p, α) and (p,³He) cross sections induced by 100 MeV protons on ⁴⁰Ca
(University of the Western Cape, 2006)Alpha clusteri ng in nuclei is studied with quasi - free knockout reactions. A beam of 100 MeV polarized protons was used in the quasi-free knockout reaction 40 ~a( p,p' a)36 Arat iThemba LABS. While the scattered protons ... -
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 ... -
Intense pulsed neutron generation based on the principle of plasma immersion ion implantation technique (PIp3s) technique
(University of the Western Cape, 2006)The development of a deuterium deuterium/ tritium-deuterium (D-D/ D-T) pulsed neutron generator based on the principle of the Plasma Immersion Ion Implantation 1Pl) technique is presented, in terms of investigating development ... -
Cross-sectional transmission electron microscopy of nickel silicide formation
(University of the Western Cape, 1993)Silicides play a significant role in modern device technology. The operation of electronic devices heavily relies on the specific properties of metal-semiconductor interfaces. Although semiconductor technology has proven ... -
Antimicrobial activity of South African red algal secondary metabolites
(UWC, 2001)Infectious diseases, for example, measles, scarlet fever, malaria, tuberculosis, and cholera have claimed many lives. These infections are caused by pathogenic viruses, bacteria, or fungi that invade the body's tissues and ... -

The influence of maternal nicotine exposure on neonatal rat trachea development and alveoli status
(University of the Western Cape, 2000)The aim of this study was to determine the effect of maternal nicotine exposure on the status of the rat tracheal development as well as the rat lung of 7 to 42 day old offspring. Wistar dams were injected subcutaneously, ... -
Pre-equilibrium cross section calculations with a realistic effective nucleon-nucleon interaction
(University of the Western Cape, 1995)The principle aim of this work is to improve the way in which pre-equilibrium double differential cross-sections are currently calculated [1, 2, 3, 4]. The theoretical basis for these calculations is the Multistep Direct ... -
(p.n.) Reactions on 59co in the intermediate energy range
(University of the Western Cape, 1992)Detailed theoretical investigations [Chi80,Mos82,Kle85] of (p,n) and (p,p') data indicate that the reaction mechanisms operative at intermediate energies and for energy losses up to several tens of MeV are predominantly ... -
Calibration of germanium detectors for applications of radiometric methods in South Africa.
(University of the Western Cape, 2001)AII materials that are radioactive emit characteristic gamma-radiation. Natural radioactivity can be used in heavy minerals exploration and processing, as well as in understanding sediment transport. processes in coastal ... -
Investigation of stains existing on fossil samples from the sterkfonfein archeaologica sites
(University of the Western Cape, 2006)It is known that fossilized bone samples excavated from the Sterkfontein archaeological sites have prominent brown stains on their surfaces. Their existence has been postulated by researchers from Transvaal museum to be ... -
