TiO2 nanotube based dye- sensitised solar cells
(University of Western Cape, 2012)
This work investigated the synthesis of Al2O3-coated TiO2 nanotubes via the anodisation technique for application in DSCs. TiO2 nanotube arrays with
an average length of 15 μm, diameter of 50 nm and wall thickness of 15 ...
The ecology of the world's smallest tortoise, homopus signatus signatus: effects of rainfall
(2008)
Tortoises appear to be successful in arid ecosystems, where they depend on primary production for their predominantly herbivorous diets. The low primary production of arid regions is exacerbated by priodic droughts, so ...
Phylogeography and speciation in the genus arthroleptella
(2009)
Moss frogs are restricted to permanently moist terrestrial habitats in the south-western Cape Fold Mountains. There is a very close association between Arthroleptella distribution and Table Mountain Sandstone. Suitable ...
Dynamic variation of hydrogen dilution during hot-wire chemical vapour deposition of silicon thin films
(University of the Western Cape, 2013)
This study reports on the effects of hydrogen dilution and deposition time on six silicon thin films deposited at six specific deposition regimes. The thin film properties are investigated via X-Ray diffraction analysis, ...
Spectrally selective AlXOY/Pt/AlXOY solar absorber coatings for high temprature solar-thermal applications
(University of Western Cape, 2014)
The limited supply of fossil hydrocarbon resources and the negative impact of CO2 emission on the global environment dictate the increasing usage of renewable energy sources. Concentrating solar power (CSP) systems are the ...
Evaluation of antihistamines for in vitro antimalarial activity against Plasmodium falciparum
(2010)
The declining efficacy of antimalarial drugs against resistant Plasmodium falciparum strains in several endemic regions has amplified the world’s burden of neglected diseases. This has highlighted the need for alternate ...
Filament carburization during the hot-wire chemical vapour deposition of carbon nanotubes
(University of the Western Cape, 2008)
This study reports on the changes in the structural properties of a tungsten-filament when exposed to a methane / hydrogen ambient for different durations at various filament-temperatures.
Intra- and inter-population variation in the bladder grasshopper Bullacris unicolor
(University of the Western Cape, 2014)
Although the processes that promote biodiversity and speciation remain poorly understood, ecological factors are thought to be one of the causal agents responsible for promoting variation. Bladder grasshoppers (Orthoptera; ...
Structure property relationship and thermal stability of organic photovoltaic cells
(University of the Western Cape, 2010)
In this thesis, regioregularpoly( 3-hexylthiophene) (rr-P3HT) polymer was used as a light absorption and electron donating material, while the C60 fullerene and its derivative [6,6]-phenyl C61-butyric acid methyl ester ...
An investigation into the morphology of radio sources
(University of Western Cape, 2021)
Radio galaxies are some of the most unusual and powerful objects in the Universe
and are therefore vital for so many reasons. Studies of Radio-Loud Active
Galactic Nuclei (AGN) gives us the potential to enhance our ...
