Development of Metal Nanoparticle-Doped Polyanilino-Graphene Oxide High Performance Supercapacitor Cells
(University of the Western Cape, 2018)
Supercapacitors, also known as ultracapacitors or electrochemical capacitors, are considered
one of the most important subjects concerning electricity or energy storage which has proven
to be problematic for South Africa. ...
Novel aromatic dendritic-co-poly(3-hexylthiophene) composites for photovoltaic cell application
(University of Western Cape, 2021)
Fossil fuels are part of fuels that are formed from natural processes and they are called non-renewable sources of energy. These include natural gas, coal and oil. They have been used for decades to produce energy globally. ...
Microwave synthesized ruthenium antimony oxide-graphene nanocomposite materials for asymmetric supercapacitors
(University of the Western Cape, 2022)
With the rapid rise in energy demand and ever-escalating environmental hazards, the need for transition from fossil fuel to renewable energy sources is of paramount importance, requiring better and efficient energy storage ...
Electro-analytical protocols for quantitative assessment of phenols in South African rooibos, green and black tea samples
(University of Western Cape, 2022)
The worldwide tea market was estimated at almost 200 billion U.S. dollars in 2020. It is perceived to rise to 318 billion dollars by 2025. Tea has a long history of prominence around the world. Increases in tea production ...
Identification, separation and quantification of persistent organic pollutants using capillary electrophoresis
(University of the Western Cape, 2022)
Water quality deterioration and scarcity can be attributed to natural causes and anthropogenic activities which include climate change and an incessant industrialisation, yet with lack of functional and reliable wastewater ...
Phytochemical and biological studies of extracts from selected South African indigenous medicinal plants: Bulbine and helichrysum species
(University of the Western Cape, 2022)
Medicinal plants from the Asteraceae and Asphodelaceae families are among the most widely recognized in South African traditional medicine for managing diabetes mellitus. Diabetes mellitus is a universal epidemic, yet there ...
Phytochemical studies on extracts of selected South African indigenous medicinal plants
(University of the Western Cape, 2022)
Nature has been identified as a rich source of potentially useful chemicals. Throughout the years, phytochemical studies have led to the unearthing of a huge number of natural products, their chemical diversity is unique ...
A comparative energy storage efficiency study of multiple cation doped LiMxMn2-xO4/MWCNT cathodes for advanced Li-ion batteries
(University of the Western Cape, 2022)
The current lithium-ion battery which is used in most technological applications is the LiCoO2
(LCO) battery. This battery offers a high theoretical capacity of 274 mAh.g-1. Scientists have
however deemed this battery ...
Synthesis of new biguanide derivatives as potential antidiabetic drugs
(University of the Western Cape, 2022)
The main purpose of this study was to synthesize biguanide compounds with potential as
antidiabetic drugs. All biguanide compounds possess antidiabetic properties by decreasing the
blood glucose level. Hence, we embarked ...
The Synthesis of Biaxial Naphthoquinones and an Initial Investigation regarding their Potential as anti- Mycobacterium tuberculosis and Apoptotic Agents
(University of the Western Cape, 2009)
Tuberculosis and cancer are amongst the most devastating diseases affecting the world today, especially Africa and other less developed countries. Both diseases have the ability to develop resistance against drugs being ...
