Simulating the neutral hydrogen distribution during cosmic reionization
(University of the Western Cape, 2018)
We improve on the physical treatment of ionising source and sink populations
in the large scale semi-numerical simulations by implementing new physically
motivated parametrizations taken from high-resolution radiative ...
Post-deposition doping of silicon nanowires
(University of the Western Cape, 2018)
Silicon nanowires (Si NWs) continue to demonstrate superior properties to their bulk
counterparts, with respect to their morphological and electrical transport properties for
the use in photovoltaic (PV) applications. ...
Radon exhalation of building materials
(University of the Western Cape, 2018)
Public concern about all radiation and radon exhalation from building
materials has been highlighted recently. The purpose of this study is
to address this public concern and to investigate the contribution of
building ...
Feasibility of Nuclear Plasma Interaction studies with the Activation Technique
(University of the Western Cape, 2018)
Electron-mediated nuclear plasma interactions (NPIs), such as Nuclear Excitation
by Electron Capture (NEEC) or Transition (NEET), can have a signi cant impact
on nuclear cross sections in High Energy Density Plasmas (HEDPs). ...
Macroscopic and Microscopic surface features of Hydrogenated silicon thin films
(University of the Western Cape, 2018)
An increasing energy demand and growing environmental concerns regarding the use of fossil
fuels in South Africa has led to the challenge to explore cheap, alternative sources of energy.
The generation of electricity from ...
Nuclear structure studies in the A=136 region using transfer reactions
(University of the Western Cape, 2018)
This thesis describes research work undertaken to study neutron pairing correlations
in 136Ba via the 138Ba(p, t) pair transfer reaction and to perform
high-precision spectroscopy of low-lying states in 136Cs using the ...
Tin Catalyst preparation for Silicon Nanowire synthesis
(University of the Western Cape, 2018)
Solar cells offer SA an additional energy source. While Si cells are abundantly
available they are not at an optimal efficiency and the cost is still high. One
technology that can enhance their performance is SiNW. ...
Investigating the Gamma-ray Strength Function in 74Ge using the Ratio Method
(University of the Western Cape, 2018)
An increasing number of measurements reveal the presence of a low-energy enhancement
in the gamma-ray strength function (GSF). The GSF, which is the
ability of nuclei to absorb or emit
rays, provides insight into the ...
Neutral hydrogen in galaxies, its content and the effect of environment on its evolution
(University of the Western Cape, 2018)
Using two hydrodynamic galaxy formation simulations from the Mufasa project that I helped
develop, we aim to better understand the relationship between galaxy evolution and its cold gas
content commonly known as the ...
