Structural and physical properties of ReN i03 (Re=Sm, N d) nanostructured films prepared by Pulsed Laser Deposition
(University of the Western Cape, 2010)
Very few systems allow the study of the relationship between structural changes and physical properties in such a clear way as rare earth nickelate ReNi03 perovskites (Re (rare earth) = Pr, Nd, Sm and Gd). Synthesized for ...
Radio-optical analysis of extended radio sources in the first look survey field
(2010)
I combine 610 MHz Giant Metrewave Radio Telescope (GMRT) data, 1.4 GHz Very
Large Array (VLA) data and 1.4 GHz Westerbork Synthesis Radio Telescope (WSRT)
observations, encompassing a ∼ 4 square degree field (sq. deg. ...
Fabrication and characterization of a solar cell using an aluminium p-doped layer in the hot-wire chemical vapour deposition process
(2010)
When the amorphous silicon (a-Si) dangling bonds are bonded to hydrogen the concentration of the dangling bond is decreased. The resulting film is called hydrogenated amorphous silicon (a-Si:H). The reduction in the dangling ...
Infrared-bright galaxies in the millennium simulation and Sunyaev Zeldovich effect contamination
(2010)
Measuring the evolution of the abundance of galaxy clusters puts constraints on cosmological parameters like the cosmological density parameter m, σ8 and the dark energy equation of state parameter, w. Current observations ...
Modelling radio galaxies in the Millennium simulation: SKA/MeerKAT sources and CMB contaminants
(University of the Western Cape, 2010)
We investigate the modelling of radio galaxies within a semi-analytic framework in the Millennium Simulation of the Virgo Consortium. The aim is to assess the radio sources contamination of Sunyaev-Zeldovich (SZ) signatures ...

Stellar masses of star forming galaxies in clusters
(University of the Western Cape, 2010)
We determine the stellar mass of star forming galaxies in the X-ray luminous cluster MS 0451.6-0305 at z ∼ 0.54. The stellar masses are estimated from fitting model spectral energy distributions (SEDs) to deep, optical ...
Towards stimuli-responsive functional nanocomposites: smart tunable plasmonic nanostructures Au-VO2
(University of the Western Cape, 2010)
The fascinating optical properties of metallic nanostructures, dominated by collective oscillations of free electrons known as plasmons, open new opportunities for the development of devices fabrication based on noble metal ...
Luminous red galaxies in simulations
(2010)
There have been a number of attempts to measure the expansion rate of the Universe using age-dating of Luminous Red Galaxies (LRGs).Assuming stars in LRGs form at the same time, age-dating of two populations of LRGs at ...
Radon escape from water
(University of the Western Cape, 2010)
This thesis aims to measure the rate of radon loss from water in a systematic way. The dependence on surface area, temperature and concentration will be investigated. The experiments were done at UWC by creating radon using ...
