Determination of the Spectroscopic Quadrupole moment of the first 2+ excited state in 32S
(University of the Western Cape, 2019)
In this work we have determined the spectroscopic or static quadrupole moment
of the rst excited state (QS (2+1) lying at 2230.6 keV in 32S using the reorientation
e ect. The Coulomb-excitation experiment at safe ...
Synthesis and characterization of silver nanoparticles for photovoltaic application
(2013)
With an increase in the amount of harmful carbon emissions in the atmosphere as well as a decrease in the availability of fossil fuels, there is a relatively high demand for alternate energy devices. Solar cells have become ...
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 ...
Macroscopic and Microscopic surface features of Hydrogenated silicon thin films
(University of the Western Cape, 2018)
An increasing energy demand and growing environmental concerns regarding the use of fossil
fuels in South Africa has led to the challenge to explore cheap, alternative sources of energy.
The generation of electricity from ...
Radiometric characterisation of vineyard soils, Western Cape, South Africa
(University of the Western Cape, 2010)
This study is aimed at investigating the feasibility of using the radiometric technique as an alternative to traditional methods for determining soil physico-chemical parameters which are important for terroir characterization. ...
Nuclear structure studies in the A=136 region using transfer reactions
(University of the Western Cape, 2018)
This thesis describes research work undertaken to study neutron pairing correlations
in 136Ba via the 138Ba(p, t) pair transfer reaction and to perform
high-precision spectroscopy of low-lying states in 136Cs using the ...
Testing gravity with redshift-space distortions, using MeerKAT and the SKA
(University of the Western Cape, 2019)
The growth rate of large-scale structure is a key probe of gravity in the accelerating
Universe. Standard models of Dark Energy within General Relativity predict essentially
the same growth rate, whereas Modified Gravity ...
Proton conductivity stability studies by modelling
(University of the Western Cape, 2016)
In this thesis, some of the challenges experienced by high temperature polymer electrolyte
membrane fuel cells are explored through material modelling techniques. A very important
aspect for a fuel cell is that it should ...
Synthesis of zinc oxide nanoparticles by a green process and the investigation of their physical properties
(University of the Western Cape, 2017)
Zinc oxide (ZnO) is a wide and direct semiconductor with a wurtzite crystal structure. Its
multifunctionality as the ideal candidate in applications such as blue-UV light emitting
diodes, transparent conducting oxide, ...
Tin Catalyst preparation for Silicon Nanowire synthesis
(University of the Western Cape, 2018)
Solar cells offer SA an additional energy source. While Si cells are abundantly
available they are not at an optimal efficiency and the cost is still high. One
technology that can enhance their performance is SiNW. ...
