Modification of nanostructured carbon based supports for direct methanol fuel cells
(University of the Western Cape, 2022)
Palladium (Pd) and Palladium-Ruthenium (Pd-Ru) nanoparticles supported by various carbon
nanomaterials which include graphene oxide (GO), reduced graphene oxide (rGO) and multiwalled
carbon nanotubes (MWCNTs) with their ...
Supported catalysts for CO2 cycloaddition reactions
(University of the Western Cape, 2022)
Carbon dioxide (CO2) is a major greenhouse gas (GHG) released into the environment
due to increasing human activities. Cyclic carbonates on the other hand, are valuable
compounds with several functions such as, polar ...
Nanostructured europium and palladium oxide substituted lithium manganese oxide [lieu(x)pdo(y)mno3] perovskite material for li ion battery cathode
(University of the Western Cape, 2022)
The 4th Industrial revolution which is to be mainly powered by cleaner energy technologies has necessitated the scientific community to develop new high-tech energy storage materials. Furthermore, 4IR is associated with ...
Polyphenolic, tannin and chemical compositional changes in leaves of sub-tropical grasses and fynbos shrubs at elevated atmospheric CO2 concentrations
(University of the Western Cape, 2002)
The effects of elevated atmospheric CO2 concentrations on plant polyphenolic concentration, tannin concentration and chemical composition were investigated in leaves of sub-tropical grass species and fynbos shrubs. The ...
Solid phase micro extraction: an alternative technique for the determination of volatile orgnanic compounds in groundwater
(University of the Western Cape, 2004)
Standard methods for sample preparation use toxic organic solvents and can be replaced by utilizing a new sample preparation and concentration technique. One such technique, compatible with capillary gas chromatography was ...
Synthesis and evaluation of metformin derivatives for anti-diabetes
(University of the Western Cape, 2022)
Type 2 diabetes mellitus (T2DM) is a significant public health crisis and is placed amongst the top ten leading causes of death worldwide. Metformin is the first-line drug used to treat T2DM, which is mainly attributed to ...
Phytochemical synthesis and antimicrobial application of gold nanoparticles from extract of Artemisia annua
(University of the Western Cape, 2023)
Metallic nanoparticles synthesized using chemical methods and physical methods are considered toxic to the environment due to the use of toxic solvents. The biological synthesis methods such as the use of plant extracts ...
Effect of synthetic methods on the characteristics and performance of IrO2 catalysts
(University of the Western Cape, 2022)
For many years fossil fuel has been the primary source of energy worldwide though, the
environment is negatively affected because of the high carbon dioxide (CO2) emissions
associated with the use of fossil fuels. Hydrogen ...
Nanostructured materials for sustainable next generation organic solar cells
(University of the Western Cape, 2022)
Many researchers are conducting their studies that are centred on using solar energy to generate
electricity due to the developing interest in solar energy. One of the most promising options to reduce
the cost of ...
Effluent water treatment utilising a combination of hydrodynamic shear and flotation technology for the specific application of wastewater from the oil and gas industry
(University of the Western Cape, 2022)
Water plays an important role in the petrochemical production and refining processes. The
wastewaters released by these processes are often rich in petroleum pollutants, that requires
significant treatment prior to ...
