Structural and gas sensing properties of TiO₂-based (Sn, Mg) nano-structures induced by mechanical milling and annealing
(University of the Western Cape, 2015)
Titanium oxynitride has attracted research interest for the fact that it is a bioactive
non-toxic material. It is suitable for surface coating of biomaterials and in other
applications such as anti-reflective coatings, ...
Vertically aligned silicon nanowires synthesised by metal assisted chemical etching for photovoltaic applications
(University of the Western Cape, 2015)
One-dimensional silicon nanowires (SiNWs) are promising building blocks for solar cells as they provide a controlled, vectorial transport route for photo-generated charge carriers in the device as well as providing ...
Developing a sorting code for Coulomb excitation data analysis
(University of the Western Cape, 2015)
This thesis aims at developing a sorting code for Coulomb excitation studies
at iThemba LABS. In Coulomb excitation reactions, the inelastic scattering
of the projectile transfers energy to the partner nucleus (and ...
Modelling the growth of large-scale structure with interacting fluids
(University of the Western Cape, 2015)
Prevailing astronomical and astrophysical observations suggest that we live in a spatially flat cold dark matter (CDM) universe - currently going through a period of accelerated expansion possibly driven by “dark energy” ...
Effect of the additional electron acceptor in hybrid ZnO: P3HT:PCBM spin-coated films for photovoltaic application
(University of the Western Cape, 2015)
In a quest for low operational and maintenance cost solar cell devices, organic photovoltaics remain a potential source of energy worthy to be explored. In order to generate cost- effective electricity from solar energy, ...
Deposition of silicon nanostructures by thermal chemical vapour deposition
(University of the Western Cape, 2015)
In this thesis we report on the deposition of silicon nanostructures using a 3-zone thermal chemical vapour deposition process at atmospheric pressure. Nickel and gold thin films, deposited by DC sputtering on crystalline ...
The nature of the microjy source population
(University of the Western Cape, 2015)
The study of the faint radio universe and of its properties has recently become a very active field of research not only because of the much improved capabilities of the SKA pathfinders but also because of the need to ...
The impact of environment and mergers on the H I content of galaxies in hydrodynamic simulations
(University of the Western Cape, 2015)
We quantitatively examine the effects of merger and environment within a cosmological hydrodynamic simulation. We show that our simulation model broadly reproduces the observed scatter in H I at a given stellar mass as ...
Relativistic corrections to the power spectrum
(University of the Western Cape, 2015)
The matter power spectrum is key to understanding the growth of large-scale structure in the Universe. Upcoming surveys of galaxies in the optical and HI will probe increasingly large scales, approaching and even exceeding ...
