Nitrogen and argon treatment of titanium dioxide nanowire arrays
(University of the 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 ...
Photo-physical properties of lead-tin binary Perovskite thin films
(University of Western Cape, 2021)
Organic-inorganic lead-based perovskite has exhibited great performance in the past few years.
However, the lead (Pb) embedded in those compounds is a significant drawback to further
progress, due to its environmental ...
The use of remote sensing data for assessing water quality in wetlands within the Limpopo River Basin
(University of the Western Cape, 2021)
Wetlands are unique ecosystems that are acknowledged among the world’s most productive and valuable ecosystems. They are recognized as being essential to sustainable development and human welfare due to their unique ...
Selected antiretroviral and anti-tuberculosis drug combinations by non-covalent bonding
(University of Western Cape, 2021)
Treatment of the human immunodeficiency virus (HIV) and tuberculosis (TB) infections have become very complicated due to the advent of drug resistance. Drug combinations offer an alternative approach to reducing the emergence ...
Silicon nanowires by metal-assisted chemical etching and its incorporation into hybrid solar cells
(University of Western Cape, 2021)
The rapid increase in global energy demand in recent decades coupled with the adverse environmental impact of conventional fuels has led to a high demand for alternative energy sources that are sustainable and efficient. ...
Remote sensing drought impacts on wetland vegetation productivity at the Soetendalsvlei in the Heuningnes Catchment, South Africa
(University of Western Cape, 2021)
This work aimed at assessing the response of wetland vegetation productivity to the 2014-2017 climate-induced drought at the Soetendalsvlei wetland system in the Western Cape province of South Africa. To achieve this ...
Carbon sequestration in cultivated and uncultivated Vachellia karroo sites in Tankwa Karoo National Park
(University of Western Cape, 2021)
The Succulent Karoo Biome (SKB) in South Africa is widely reputed to house Earth’s greatest diversity of succulent plants. It is also famous for spectacular displays of annual flowers after good rains. The area experiences ...
The use of well log data in the creation of 3D geological maps
(University of the Western Cape, 2021)
Three-dimensional (3D) graphic representations of geographic environments have become
commonplace in a range of elds. These representations are often an attempt to
represent both geographic forms, as well as the ...
Exploring the factors influencing the sustainability of mobile clinics for the delivery of the expanded programme on immunisation to the rural areas of the Northern Cape.
(University of Western Cape, 2021)
The Northern Cape province has not been able to achieve the 90% immunization target recommended for South Africa’s expanded programme on immunisation (EPI). The situation has been attributed to the lack of access to EPI ...
Hydrothermal synthesis of hierarchical ZSM-5 with different Si/Al ratio and their evaluation as catalysts in the catalytic cracking of hexane
(University of Western Cape, 2021)
Ethylene and propylene are greatly used for their importance as feedstocks for producing useful materials. Due to rise in prices and the demand of ethylene and propylene, the need to increase the selective production of ...
