Optical and electronic properties of methylammonium lead halide perovskite solar cells
(University of the Western Cape, 2017)
Organic-inorganic hybrid perovskite solar cells have emerged as promising materials for next-generation
photovoltaics with certified efficiency of 22.1%. Despite rapid developments, achieving precise control
over the ...
Synthesis and characterisation of high silica zeolites with MOR and MFI framework type from South African coal fly ash.
(University of the Western Cape, 2019)
High-silica zeolites are porous, aluminosilicate materials known for high thermal stability;
making these materials favourable for application in various industrial processes involving
elevated temperatures. The synthesis ...
Sustainable synthesis of BEA zeolite from fly ash-based amorphous silica
(University of Western Cape, 2019)
Power generation in South Africa depends majorly on the combustion of coal and the
increasing demand for energy due to industrialisation and population growth signifies the
continuous consumption of coal. During this ...
Electrochemical ochratoxin a immunosensors based on polyaniline nanocomposites templated with amine- and sulphate-functionalised polystyrene latex beads
(University of the Western Cape, 2010)
Polyaniline nanocomposites doped with poly(vinylsulphonate) (PV-SO3) and nanostructured polystyrene (PSNP) latex beads functionalized with amine (PSNP-NH2) and sulphate ((PSNP-OSO3) were prepared and characterised for use ...
Degradation of persistent organic pollutants (pharmaceuticals & dyes) by combined dielectric barrier electrohydraulic discharge system and photo catalysts
(University of the Western Cape, 2019)
Water pollution problems have continued to increase not only in South Africa but worldwide due to human activities. The presence of organic toxins and bacteria in water sources is mostly due to population growth, industrial ...
Chromium and Titanium based Stannum Nanocomposites materials as electron acceptors for next generation bulk Heterojunction photovoltaic cells
(University of the Western Cape, 2018)
Renewable energy has become the centrepiece of research in resolving the energy
crisis. One of the forms of renewable energy is solar energy. This form of energy is
costly to develop. Organic molecules are promising materials ...

(University of the Western Cape, 2011)
To meet a fast-growing market demand for next generation portable electronic devices with higher performance and increased device functionalities, efficient electrical energy devices with substantially higher energy, power ...
Highly selective mesoporous sorbents for mercury removal from industrial wastewater
(University of the Western Cape, 2011)
The results of this study show that novel mesoporous carbons were obtained as inverse replica of SBA-15, HMS and MCM-41 silica templates, with a large pore diameter (2-4 nm), a BET surface area of 1867, 874 and 910 m2g–1 ...
Synthesis and electrochemistry of novel conducting dendrimeric star copolymers on poly(propylene imine) dendrimer
(University of the Western Cape, 2011)
One of the most powerful aspects of conducting polymers is their ability to be nanostructured through innovative, synthetically manipulated, transformations, such as to tailor-make the polymers for specialized applications. ...
Investigation of anti-cancer potential of Pleiocarpa pycnantha leaves
(University of the Western Cape, 2013)
The Apocynaceae family is well known for its potential anticancer activity. Pleiocarpamine isolated from the Apocynaceae family and a constituent of Pleiocarpa pycnantha has been reported for anti-cancer activity. Prompted ...
