Nonlinear optical properties of natural dyes based on optical resonance
(University of the Western Cape, 2012)
Recent research shows that the study of optical properties of organic material natural dyes has gained much consideration. The specific functional groups in several natural dyes remain essential for the large nonlinear ...
Hot-wire chemical vapour deposition of nanocrystalline silicon and silicon nitride : growth mechanisms and filament stability
(University of the Western Cape, 2012)
Nanocrystalline silicon (nc-Si:H) is an interesting type of silicon with superior
electrical properties that are more stable compared to amorphous silicon (a-Si:H).
Silicon nitride (SiNₓ) thin films are currently the ...
Plasma characterisation of an electron cyclotron resonance ion source by means of x-ray spectroscopy
(University of the Western Cape, 2012)
The ultimate aim of any multiply-charged ion source, like the Electron Cyclotron Resonance Ion Source, ECRIS, is the production of multiply-charged ions, in sufficiently large quantities. These multiplycharged ions, in the ...
An Investigation of magnetic storm effects on total electron content over South Africa for selected periods in solar cycles 23 and 24
(University of the Western Cape, 2012)
The development of regional ionospheric Total Electron Content (TEC) models has contributed to understanding the behavior of ionospheric parameters and the coupling of the ionosphere to space weather activities on both ...
TiO₂ nanotube based dye-sensitised solar cells
(University of the Western Cape, 2012)
The first report of a functioning photo-electrochemical solar cell in 1991 attracted a lot of interest from scientists and industrial groups. From an industrial point of view these so-called dye-sensitised solar cells ...
Thermochromic properties of VO2 nano-coatings by inverted cylindrical magnetron sputtering
(University of the Western Cape, 2012)
Vanadium dioxide (VO2) films have been known as the most feasible thermochromic nano-coatings for smart windows which self control the solar radiation and heat transfer for energy saving and comfort in houses and automotives. ...
TiO2 nanotube based dye- sensitised solar cells
(University of Western Cape, 2012)
This work investigated the synthesis of Al2O3-coated TiO2 nanotubes via the anodisation technique for application in DSCs. TiO2 nanotube arrays with
an average length of 15 μm, diameter of 50 nm and wall thickness of 15 ...
Perturbations of dark energy models
(University of Western Cape, 2012)
The growth of structure in the Universe proceeds via the collapse of dark matter
and baryons. This process is retarded by dark energy which drives an accelerated
expansion of the late Universe. In this thesis we use ...
