Latent and thermal energy storage enhancement of silver nanowires-nitrate molten salt for concentrated solar power
(University of Western Cape, 2020)
Phase change material (PCM) through latent heat of molten salt, is a convincing way for thermal energy storage in CSP applications due to its high volume density. Molten salt, with (60% NaNO3 and 40% KNO3) has been used ...
Nitrogen and argon treatment of titanium dioxide nanowire arrays
(University of Western Cape, 2021)
TiO2 nanoparticle films are important electron transport layers (ETLs) in photovoltaics such as dye-sensitised, perovskite and polymer hetero-junction solar cells. These films, however, have significant electron trap-sites ...
Neutral hydrogen intensity mapping on small scales using MeerKAT
(University of the Western Cape, 2021)
In the post-reionisation universe, intensity mapping (IM) with the 21 cm line of neutral hydrogen (HI) provides a potential means of probing the large-scale structure of the universe. With such a probe, a wide variety of ...
A relativistic analysis of proton-induced knockout reactions from oxygen isotopes with direct and inverse kinematics.
(University of the Western Cape, 2020)
In this study a complete set of exclusive (~p; 2p) polarization transfer observables of closed-shell oxygen
isotopes are calculated using both direct and inverse kinematics using the relativistic plane wave impulse
app ...
Application of vertically aligned arrays of metal-oxide nanowires in heterojunction photovoltaics
(University of the Western Cape, 2020)
The commercial need to improve the performance of low-cost organic solar cells has led to the idea for this research. The study discusses the synthesis of one dimensional TiO2 and ZnO nanowire arrays synthesised using a ...
Giant Magnetocaloric effect and Magnetic Properties of selected Rare-Earth compounds
(University of the Western Cape, 2021)
Rare-earth (RE) compounds have been an attractive subject, based on the unique electronic structures of the rare-earth elements. In particular, the RETX (RE = rare-earth, T = 3d/4d/5d, transition metals, and X = p – block ...
A multi-scale study of the star formation law in nearby galaxies
(University of the Western Cape, 2020)
This research aimed to evaluate the effects of changing length-scales on the star formation
laws and star formation efficiencies for our selected sample of galaxies. We have combined
high-resolution Hi data from The Hi ...
Triaxiality and rotational bands in 133ce
(University of Western Cape, 2021)
The neutron-de cient nuclei between the N = 50 and N = 82 shell closures provide
rich information on the shape and structure of the nucleus. The isotones of 133Ce
and 131Ba (N = 75) lie in this region of the nuclear ...
Probing large-scale structure with the SKAO and other cosmological surveys
(University of the Western Cape, 2022)
In recent history there have been several advances in cosmology, which has significantly
shaped our understanding of the Universe. The current leading theory is called ΛCDM,
which can successfully model the expansion of ...
A multi-wavelength study of powerful high redshift radio galaxies
(2021)
We present a new sample of distant powerful radio galaxies, in order to study their
host-galaxy properties and provide targets for future observations of Hi absorption
with new radio telescopes. We cross-match the Sydney ...
