Hot-wire chemical vapour deposition of carbon Nanotubes
(University of the Western Cape, 2006)In this study we report on the effect of the deposition parameters on the morphology and structural properties of CNTs, synthesized by means of the hot-wire chemical vapour deposition technique. SEM, Raman and XRD results ... -
Intense pulsed neutron generation based on the principle of Plasma Immersion Ion Implantation (PI3) technique
(University of the Western Cape, 2006)The development of a deuterium-deuterium/ tritium-deuterium (D-D/ D-T) pulsed neutron generator based on the principle of the Plasma Immersion Ion Implantation (PI3) technique is presented, in terms of investigating ... -
Emission of ³He ⁴He and ⁶He particles produce from the interaction of ¹²C with ⁹³Nb at 400 MeV incident energy
(University of the Western Cape, 2005)The inclusive double di®erential cross sections of 3He, 4He, and 6He par- ticles produced from the interaction of 12C with 93Nb at 400 MeV incident energy were extracted from the prescaled singles spectra which were ... -
Study of magnetic properties of nanostructures on self-assembled patterns
(University of the Western Cape, 2010)In the current study, we give a report when oxalic acid was used as an electrolyte to synthesize an AAO template with hexagonal pore array. Optimum parameters were observed as 0.4 M of oxalic acid, anodizing voltage of 45 ... -
Modelling and measurement of radon diffusion through soil for application on mine tailings dam
(University of the Western Cape, 2004)Radon has been identified as an important factor that could result in a health hazard by studies all around the world. The health risks can be minimised by preventive measures where radon is highly concentrated as in some ... -
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 ... -
Modeling of the dispersion of radionuclides around a nuclear power station
(University of the Western Cape, 2009)Nuclear reactors release small amounts of radioactivity during their normal operations. The most common method of calculating the dose to the public that results from such releases uses Gaussian Plume models. We are ... -
Determination of natural radioactivity concentrations in soil: a comparative study of Windows and Full Spectrum Analysis
(University of the Western Cape, 2004)In this study, two methods of analysing activity concentrations of natural radionuclides (U, Th and K) in soil are critically compared. These are the Window Analysis (WA) and Full Spectrum Analysis (FSA). In the usual WA ... -
Determination of the photopeak detection efficiency of a HPGe detector, for volume sources, via Monte Carlo simulations
(University of the Western Cape, 2005)The Environmental Radioactivity Laboratory (ERL) at iThemba LABS undertakes experimental work using a high purity germanium (HPGe) detector for laboratory measurements. In this study the Monte Carlo transport code, MCNPX, ... -
Radon in the Cango Caves
(University of the Western Cape, 2005)Radon is a naturally occurring radioactive element in the 238U decay series that is found in high concentrations in certain geological formations such as Caves. Exposure to high concentrations of radon has been positively ... -
Gamma spectroscopy of the doubly– ODD 194Tl Nucleus
(University of the Western Cape, 2006)The odd – odd Tl nuclei with A ≥ 190 have moderate oblate nuclear deformation and show rotational bands built on different quasiparticle excitations. Several phenomena, not yet fully understood, were observed in these ...
