The Isolation and Electrochemical Studies of Flavanoids from Galenia africana and Elytropapus rhinocerotis from the North Western Cape
(University of the Western Cape, 2010)
In this study two medicinal plant species, namely Galenia africana and Elytropapus rhinocerotis, the former belonging to the family Aizoceae and the latter belonging to the family Asteraceae, have been investigated and ...
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 ...
Electrochemical characterization of nanostructured SnO2 and TiO2 for potential application as dielectric materials in sulfonated-polyaniline based supercapacitors
(University of the Western Cape, 2010)
In this research project, nanostructured composites based on Tin dioxide (SnO2) and Titanium dioxide (TiO2) with poly-4-styrene sulfonic acid (PSSA) doped polyaniline (PANI) conducting polymer has been investigated based ...
Polymeric tyrosinase nanobiosensor system for the determination of endocrine disrupting bisphenol A
(University of the Western Cape, 2011)
The main objective of this work was to develop simple and sensitive electrochemical sensors for the detection of bisphenol A. To investigate the electrochemical behavior of BPA on a bare glassy carbon electrode. To apply ...
Synthesis of sulphonated and transition metal oxide doped polymeric nanocomposites for application in design of supercapacitors

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. ...
The development of l-phenylalanine biosensor using boron-doped diamond (bdd) electrode modified with poly aniline-polyvinyl sulphonate composite film
(University of the Western Cape, 2010)
The aim of this project was to develop a biosensor on a modified boron-doped diamond (BDD)
platform in order to determine L-phenylalanine (L-Phe) levels in the aqueous media and real
samples. A BDD electrode modified ...
Electrochemical responses of novel preferentially oriented platinum (100) nanoalloys for ammonia and hydrazine catalysis
(University of the Western Cape, 2013)
Ammonia has attracted attention as a possible fuel for direct fuel cells since it is easy to handle under low pressure, costs only slightly higher than methanol and can easily be cracked down into hydrogen and nitrogen. ...
