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 ...
A baseline evaluation of the cytotoxicity of gold nanoparticles in different types of mammalian cells for future radiosensitization studies
(University of the Western Cape, 2020)
Recently nanoparticles (NPs) have been introduced and used in combination with therapeutic approaches to develop nanotechnology-enabled medicine. These nanostructures allow for the exploitation of the physiochemical ...

Green synthesis and characterization of silver nanoparticles (AgNPs) from Bulbine frutescens leaf extract and their antimicrobial effects
(University of the Western Cape, 2020)
Combating antimicrobial resistant infections caused by nosocomial pathogens poses a major public health problem globally. The widespread use of broad-spectrum antibiotics for the treatment of wound infections has led to ...

Investigation of the anti-obesity effects of citrate-capped gold nanoparticles on 3T3-L1 cells and their genetic profiling
(University of the Western Cape, 2023)
The incidence and prevalence of obesity and its related diseases has nearly tripled and is increasing at an alarming rate worldwide. Several modern methods for the management and treatment of obesity are available, with ...
Nanostructured immunosensor for low level detection of waterborne cryptosporidium
(University of the Western Cape, 2022)
A major causative agent of gastrointestinal disease is Cryptosporidium, a protozoan
waterborne parasite identified in over 70 countries. Cryptosporidium infection is a
cause of high disease morbidity in children and the ...
