Hydrogen storage in Ti-based coatings and Ti6Al4V alloy
(University of the Western Cape, 2016)
Hydrogen has been regarded as an ideal energy carrier for future, it can be stored as a liquid in cryogenic tanks, a gas in high pressure cylinders and as solid in metal hydrides. Hydrogen storage in metal hydrides is of ...
In-situ measurements and calculation of radon gas concentration and exhalation from a tailings mine dump
(University of the Western Cape, 2013)
In Africa as well as in the world, South Africa plays an important role in the mining industry which dates back almost 120 years. Mining activities in South Africa mainly take place in Gauteng Province. Every year millions ...
Probing the large-scale structure of the universe with correlation functions
(University of the Western Cape, 2014)
In this project we explore a new statistical package called KSTAT that computes the 2PCF and higher order correlation functions, such as the 3PCF, on BOSS, making use of high performance computing facilities to improve ...
Synthesis and characterisation of 114Cd targets
(2011)
To study nuclear reactions and nuclear structures, target materials are bombarded with high-energy particles. The target material can either be in a form of a metal film or gas. A target material designed to study certain ...
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 ...
Galaxy Evolution and Cosmology using Supercomputer Simulations by Daniel Cunnama
(University of the Western Cape, 2013)
Numerical simulations play a crucial role in testing current cosmological models of
the formation and evolution of the cosmic structure observed in the modern Universe.
Simulations of the collapse of both baryonic and ...
A study of the angular momentum content of early-type galaxies
(University of the Western Cape, 2019)
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 ...
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 ...
