Supercapacitor electrode materials based on nanostructured conducting polymers and metal oxides
(University of the Western Cape, 2013)
Supercapacitors are charge-storage devices. Compared to batteries, they have higher power density, more excellent reversibility and longer cycle life. Therefore, supercapacitors have played an increasingly important role ...
Fabrication of type-I indium-based near-infrared emitting quantum dots for biological imaging applications
(University of the Western Cape, 2013)
Semiconductor nanocrystals or quantum dots (QDs) are fluorescent nanometer-sized particles
which have physical dimensions that are smaller than the excitonic Bohr radius, large surface
area-to-volume ratios, broad ...
Immunosensors developed on clathrate platform compounds
(University of the Western Cape, 2013)
Organic noncyclic compounds were used in the development of immunosensor for rapid fish species detection. Flourene derivatives show unique chemical and physical properties because they contain a rigid planar biphenyl unit, ...
Synthesis and characterization of pt-sn/c cathode catalysts via polyol reduction method for use in direct methanol fuel cell
(2013)
Direct methanol fuel cells (DMFCs) are attractive power sources as they offer high conversion efficiencies with low or no pollution. One of the major advantages DMFCs has over PEMFCs is that methanol is a liquid and can ...
Polyamic acid composites for multiiple sensing applications in complex sample matrices
(2013)
Polyamic acid-polypyrrole (PAA/PPy) composite films were prepared and characterised for the use as conducting platforms in the design of biosensor systems. The thin films were synthesised by electrochemical method from a ...
Synthesis, optical and morphological characterization of pbse quantum dots for diagnostic studies: a model study
(University of the Western Cape, 2013)
In this study PbSe quantum dots (QDs) were successfully synthesized via the organometallic and aqueous routes. Optical characterization was carried out using photoluminescence (PL) spectroscopy, structural and morphological ...
Graphenated polyaniline nanocomposite for the determination of polyaromatic hydrocarbons (pahs) in water
(2013)
The thesis presents a simple, sensitive, low cost and a novel graphenated polyaniline doped tungsten trioxide nanocomposite, as an electrochemical sensor for the detection and quantitative and determination of PAHs, which ...
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 ...
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 ...
Re-use of South African fly ash for CO2 capture and brine remediation.
(University of the Western Cape, 2013)
Coal combustion accounts for 95% of electricity generation in South Africa while globally coal combustion for energy generation stands at 42%. It has been predicted that coal utilization for energy generation will continue ...
