Disentangling star formation and AGN activity in the GAMA (G23) region
(University of the Western Cape, 2021)
Observations of galaxies at di↵erent wavelengths have shaped our understanding of their
formation and evolution through time. The commonly derived parameters, such as stellar
mass and star formation rate (SFR), rely on ...
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 ...
Construction and analysis of exponential time differencing methods for the robust simulation of ecological models
(University of Western Cape, 2021)
In this thesis, we consider some interesting mathematical models arising in
ecology. Our focus is on the exploration of robust numerical solvers which are
applicable to models arising in mathematical ecology. To begin ...
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 ...
New Collective structures in the Z=76 stable odd neutron nucleus, 187Os
(University of the Western Cape, 2021)
Low- and medium-spin bands of 187Os have been studied using the AFRODITE array, following the 186W(4He,3n)187Os reaction at a beam energy of 37 MeV. The measurements of γ − γ coincidences, angular distribution ratios (RAD), ...
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 ...
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 ...
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 ...
Effect of zinc oxide nanoridge height on solar cell performance
(University of Western Cape, 2021)
Environmentally friendly photovoltaic devices make use of solar radiation as the energy source to generate electricity. Organic solar cells (OSCs) have been making headway in the last decade due to their cost-effectiveness ...
Nial and steel as matrices and tic and oxynitrides as reinforcements in metal-matrix composite fabrication
(University of Western Cape, 2021)
Metal matrix composites harness the superior attributes of their individual constituents to form high performance materials that would rather be impossible from monolithic substances. Owing to many possible combinations, ...
