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 ... -
The fate and transport of carbon-based nanomaterials in the environment
(University of Western Cape, 2020)The interest in carbon-based nanomaterials, such as carbon-nanodots and graphene, has grown exponentially because these materials have unique properties and applications in the medical, electronic, clean energy and several ... -
Hydrothermal synthesis and optimisation of zeolite Na-P1 from South African coal fly ash
(2009)Millions of tonnes of fly ash are generated worldwide every year to satisfy the large demand for energy. Management of this fly ash has been a concern and various approaches for its beneficial use have been investigated. ... -
Hydrothermal synthesis and optimisation of zeolite Na-Pl from South African coal fly ash
(University of Western Cape, 2009)Millions of tonnes of fly ash are generated worldwide every year to satisfy the large demand for energy. Management of this fly ash has been a concern and various approaches for its beneficial use have been investigated. ... -
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 ... -
The use of synthesised USY as a dietary supplement for the removal of toxic metals (lead and cadmium) from simulated gastric juice
(University of the Western Cape, 2018)The South African economy relies heavily on mining. The residues of these activities contain harmful metals that are discharged into the environment as industrial wastes, contaminating the air, soil, surface and ground ... -
Zeolite A, X and Cancrinite from South African coal fly ash: mechanism of crystallization, routes to rapid synthesis and new morphology
(University of the Western Cape, 2012)In South Africa, almost 90 % of the country’s electricity is generated from coal combustion. This reliance on coal for energy production is projected to continue in the near and medium term due to the increasing demand for ...
