Nanoparticulate of silver-modified poly (8-anilino-1-naphthalene sulphonic acid) nanobiosensor systems for the determination of Tuberculosis treatment drugs
(University of the Western Cape, 2011)
This study firstly reports the development and characterization of PVP-AgNPs, PANSA and PVPAgNPs/ PANSA nanocomposite on gold. AFM and TEM analyses revealed highly electroactive nanocomposites whose morphogy and properties ...
Photocatalytic activity of supported TiO2 nanocrystals
(2013)
In recent times, the occurrence and presence of complex recalcitrant toxic contaminants in water and wastewater is increasing and consequently contributes to the non-availability of clean and safe drinking water. Water ...
Advanced oxidative water treatment process using an electrohydraulic discharge reactor and TiO2 immobilised on nanofibres
(University of Western Cape, 2013)
The aim of this study was to design and build an electrohydraulic discharge reactor in such a way that the synthetic immobilized TiO2 nanophotocatalytic components could be integrated, for the production of active species ...
Nanocomposite-graphene based platform for heavy metal detection
(University of the Western Cape, 2010)
This study reports the synthesis of graphene by oxidizing graphite to graphite oxide using H2SO4 and KMnO4 and reducing graphene oxide to graphene by using NaBH4. Graphene was then characterized using FT-IR, TEM, AFM, XRD, ...
Functionalisation of polymer nanofibres and track-etched membrane removal of organic and and inorganic pollutants from water
(University of the Western Cape, 2017)
Organic and inorganic pollutants are two broad classes of pollutants in the
environment with their main sources from waste waters that are indiscriminately
dumped from chemical related industries. Among the organic ...
Platinum based catalysts for the cathode of proton exchange membrane fuel cells
(University of the Western Cape, 2018)
Oxygen reduction reaction (ORR) is carried out in the cathode of the proton exchange membrane fuel cell (PEMFC) and it is known for its sluggish kinetics and the existence of two-pathway mechanism, related with the production ...
The effect of flow field design on the degradation mechanisms and long term stability of HT-PEM fuel cell
(University of the Western Cape, 2018)
Fuel cells are long term solution for global energy needs. In current fuel cell
technologies, Proton Exchange Membrane (PEM) fuel cells are known for quick start-up
and ease of operation compared to other types of fuel ...
Development of capacitive deionisation electrodes: optimization of fabrication methods and composition
(University of the Western Cape, 2017)
The objective of this research was to optimize the fabrication methods for and compositions of
electrodes for the Membrane Capacitive Deionisation (MCDI) system. Two electrode
fabrication methods were developed, namely a ...
Hydrogel encapsulated biosensors for the detection of biologically significant vanadium and selenium
(University of the Western Cape, 2017)
Vanadium and selenium salts are toxic in large amounts, but trace amounts are
necessary for cellular function in many organisms. Exposure to high level of selenium
has been linked to delays in early childhood development ...
Nanoparticles for use in imaging, catalysis and phthalocyanine synthesis
(University of the Western Cape, 2018)
Nanoscience and nanotechnology are known to be interdisciplinary, crossing and combining
various fields and disciplines in pursuit of desirable outcomes. This has brought about
applications of nanoscience and nanotechnology ...
