Lithium manganese oxide modified with copper-gold nanocomposite cladding- a potential novel cathode material for spinel type lithium-ion batteries
(University of the Western Cape, 2014)
Spinel lithium manganese oxide (LiMn2O4), for its low cost, easy preparation and nontoxicity, is regarded as a promising cathode material for lithium-ion batteries. However, a key problem prohibiting it from large scale ...
Development of high performance composite lithium ion battery cathode systems with carbon nanotubes functionalised with bimetallic inorganic nanocrystal alloys
(University of Western Cape, 2011)
Lithium ion cathode systems based on composites of lithium iron phosphate (LiFePO₄), iron-cobalt-derivatised carbon nanotubes (FeCo-CNT) and polyaniline (PA) nanomaterials were developed. The FeCo-functionalised CNTs were ...
One-Dimensional nanostructured polymeric materials for solar cell applications
(University of the Western Cape, 2010)
This work entails the preparation of various polyanilines with different morphologies and their application in photovoltaic solar cells. Zinc oxide (ZnO) with one-dimensional and flower-like morphology was also prepared ...
Preparation and physico-chemical properties of nickel nanostructured materials deposited in etched ion-track membrane
(University of the Western Cape, 2005)
The development of finely dispersed powders and superfine-grained materials intended for application in various areas of science and engineering is one of the challenges facing modern nanotechnology. Thus, specific fundamental ...
Synthesis of DMSO based silver nanoparticles for application in wound healing
(University of Western Cape, 2021)
Silver nanoparticles (AgNPs) apart from being chemically significant, have shown a lot of health benefits, the most studied being their anti-bacterial and anti-inflammatory properties. These biological properties can be ...
Synthesis and characterization of cathode catalysts for use in direct methanol fuels cells
(University of the Western Cape, 2010)
In this work a modified polyol method was developed to synthesize in-house
catalysts. The method was modified for maximum delivery of product and proved to be quick and efficient as well as cost effective. The series of ...
Characterization of platinum-group metal nanophase electrocatalysts employed in the direct methanol fuel cell and solid-polymer electrolyte electrolyser
(University of the Western Cape, 2005)
Characterization of nanophase electrocatalysts, which are an essential part in the direct methanol fuel cell (DMFC) and solid-polymer electrolyte (SPE) electrolyser, have been studied in this work. Their nanoparticulate ...
Catalyst Coated Membranes (CCMs) for polymerelectrolyte Membrane (PEM) fuel cells
(University of the Western Cape, 2010)
The main objective of this work it to produce membrane electrode assemblies (MEAs) that have improved performance over MEAs produced by the conventional manner, by producing highly efficient, electroactive, uniform catalyst ...
Synthesis and characterizations of nanostructured MnO2 electrodes for supercapacitors applications
(University of the Western Cape, 2010)
The objective of this research was to develop highly efficient and yet effective MnO2 electrode materials for supercapacitors applications. Most attention had focussed on MnO2 as a candidate for pseudo-capacitor, due to ...
