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 ...
Synthesis of sulphonated and transition metal oxide doped polymeric nanocomposites for application in design of supercapacitors
(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 ...
Preparation and characterization of highly active nano pt/c electrocatalyst for proton exchange membrane fuel cell
(University of the Western Cape, 2006)
Catalysts play an essential role in nearly every chemical production process. Platinum supported on high surface area carbon substrates (Pt/C) is one of the promising candidates as an electrocatalyst in low temperature ...
Electrochemical impedance modelling of the reactivities of dendrimeric poly(propylene imine) DNA nanobiosensors
(University of the Western Cape, 2008)
In this thesis, I present the electrochemical studies of three dendrimeric polypropylene imine (PPI) nanomaterials and their applications as a platform in the development of a novel label free DNA nanobiosensor based on ...
Fabrication of luminescent nanocomposites for diagnosis of breast cancer
(University of the Western Cape, 2016)
In this study we were able to synthesize separately iron oxide magnetic nanoparticles, InP/ZnSe
and CdTe/ZnS quantum dots. The iron oxide nanoparticles were coupled with InP/ZnSe QDs to
form the luminescent magnetic ...
Factors influencing fuel cell life and a method of assessment for state of health
(University of the Western Cape, 2018)
Proton exchange membrane fuel cells (PEMFC) converts chemical energy from the electrochemical reaction of oxygen and hydrogen into electrical while emitting heat, oxygen depleted air (ODA) and water as by-products. The ...
Development of heterostructured tin oxide nanocatalysts for the synthesis of bio-based maleic acid
(University of Western Cape, 2021)
Maleic acid (MA) is a key intermediate for the synthesis of polyester resins, surface coatings, lubricant additives, plasticizers, copolymers, pharmaceuticals and agricultural chemicals. The current industrial production ...
