A study of hydrogenated nanocrystalline silicon thin films deposited by hot-wire chemical vapour deposition (HWCVD)
(University of the Western Cape, 2005)
In this thesis, intrinsic hydrogenated nanocrystalline silicon thin films for solar cells application have been deposited by means of the hot – wire chemical vapour deposition (HWCVD) technique and have been characterised ...
Gamma spectroscopy of the doubly– ODD 194Tl Nucleus
(University of the Western Cape, 2006)
The odd – odd Tl nuclei with A ≥ 190 have moderate oblate nuclear deformation and show rotational bands built on different quasiparticle excitations. Several phenomena, not yet fully understood, were observed in these ...
Radon in the Cango Caves
(University of the Western Cape, 2005)
Radon is a naturally occurring radioactive element in the 238U decay series that is found in high concentrations in certain geological formations such as Caves. Exposure to high concentrations of radon has been positively ...
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 ...
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 ...
Determination of the gas-flow patterns inside the hot-wire chemical vapor deposition system, using computational fluids dynamics software (fluent)
(University of the Western Cape, 2009)
Computational Fluid Dynamics is the analysis of a system involving fluid flow, heat transfer and associated phenomena such as chemical reactions by means of a computer-based simulation. The simulations in this study are ...
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 ...
Metal oxide nanocrystalline thin films as buffer layers in organic/ hybrid solar cells
(University of Western Cape, 2019)
Without reverting to encapsulation, organic bulk - heterojunction solar cells
can be protected from the oxidation of the highly reactive low work function
cathode metal electrode, by the deposition of metal oxide buffer ...
Measuring the quasar luminosity function below the detection threshold
(University of the Western Cape, 2016)
The radio emission of radio-quiet active galactic nuclei (AGN) is thought to be from star formation and AGN related emission. I investigate these sources using 1.4 GHz radio data from FIRST and three optical quasars samples ...
