Development and characterization of bioceramic coatings for medicall and dental applications
(University of the Western Cape, 2007)
Hydroxyapatite (HA), which is a natural component of bone tissue, is already being marketed as a coating for the metal shafts of hip implants as well as dental screws and other endoprostheses with the expectation of improved ...
An exploration of learning by women in the clothing and textile industry within the context of the National Skills Development Strategy
(University of the Western Cape, 2008)
This study explored the learning experiences of black working class women in the context of the National Skills Development Strategy. The research focused firstly, on how the National Skills Development Strategy facilitated ...
Directional correlation from oriented states and linear poralization measurements of Gamma Rays from 190T1
(University of the Western Cape, 2008)
High-spin states in the oblate deformed odd-odd thallium nucleus ( ) 109 190 81 Tl have been investigated through the reaction 175Lu(20Ne, 5n)190Tl at a beam energy of 115 MeV. The gamma rays emitted from 190Tl nucleus ...
Manufacturing of synthetic soda ash
(University of the Western Cape, 2009)
The aim of the project was to study the manufacturing of synthetic soda ash (sodium carbonate, Na2CO3) on an industrial scale. Currently all Soda ash that is used in South Africa for manufacturing glass is imported at a ...
Charge transfer efficiency and optical properties of P3HT/PCBM spin coated thin films
(UWC, 2009)
The efficiency of organic photovoltaics is influenced by the structure of the polymer, the morphology of the film, the interfaces between the layers, the choice of electron acceptor material and the ratio between the ...
The effects of reverse bias on the efficiency of dye solar cells
(University of the Western Cape, 2009)
Dye-sensitised solar cells (DSC) have attracted much attention during the last few years due to their high efficiencies and their potentially low production costs. The technology is based on a thin layer of nano sized, ...
An investigation into the role of hydrogen embrittlement in the formation of split bodies in two-piece food cans
(2009)
Nampak packages millions of cans a year and a very small percentage of these cans fail due to many reasons. One of the main reasons that cause 2- piece food cans to fail is split flanges. Split Flanges arises due to a ...
Optical emission spectroscopy of laser induced plasmas containing carbon and transitional metals
(University of the Western Cape, 2008)
The spectroscopic, SEM and Raman measurements on carbon nanotubes under the exact conditions of which OES analysis were made showed that at a pressure of 400 Torr and a flow rate of 200 sccm, the quality and quantity of ...
Monte carlo simulations of complex germanium escape suppression spectrometers with MCNPX a case study
(University of the Western Cape, 2009)
Gamma ray spectroscopy has provided enormous amounts of information on the behaviour and structure of atomic nuclei [SHA88, BEA92, EBE08]. Most of the major discoveries in experimental nuclear physics over the last five ...
The use of FLUENT for heat flow studies of the hot-wire chemical vapor deposition system to determine the temperatures reached at the growing layer surface
(University of the Western Cape, 2009)
The overall aim of this project is to study the heat transfer inside the reaction chamber of the Hot-Wire Chemical Vapor Deposition (HWCVD) system with a commercial software package FLUENT6.3; it is one of the most popular ...
