Determination of the gas-flow patterns inside the hot-wire chemical vapor deposition system, using computational fluids dynamics software (fluent)
(University of the Western Cape, 2009)Computational Fluid Dynamics is the analysis of a system involving fluid flow, heat transfer and associated phenomena such as chemical reactions by means of a computer-based simulation. The simulations in this study are ... -
Development of platino-iridium/ruthenium telluride nanoalloy electrode systems for possible application in ammonia fuel cell
(University of the Western Cape, 2015)South Africa is undergoing a serious consideration of hydrogen economy in an effort to develop safe clean and reliable alternative energy sources for fossil fuels. Ammonia is one of the promising candidates due to its low ... -
Electrochemical responses of novel preferentially oriented platinum (100) nanoalloys for ammonia and hydrazine catalysis
(University of the Western Cape, 2013)Ammonia has attracted attention as a possible fuel for direct fuel cells since it is easy to handle under low pressure, costs only slightly higher than methanol and can easily be cracked down into hydrogen and nitrogen. ... -
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 ... -
Neutral hydrogen in galaxies, its content and the effect of environment on its evolution
(University of the Western Cape, 2018)Using two hydrodynamic galaxy formation simulations from the Mufasa project that I helped develop, we aim to better understand the relationship between galaxy evolution and its cold gas content commonly known as the ... -
Polyacrylic acid and polyvinylpyrrolidone stabilised ternary nanoalloys of platinum group metals for the electrochemical production of hydrogen from ammonia
(University of the Western Cape, 2016)The electrochemical oxidation of ammonia has attracted much attention as an efficient green method for application in direct ammonia fuel cells (DAFCs) and the production of high purity hydrogen. However, the insufficient ... -
Synthesis and characterization of biopolymer nanoapatite composite electrospun bioactive scaffold: A potential application for guided tissue/bone regeneration
(University of the Western Cape, 2019)Search for an ideal scaffold for guided tissue/bone (GTR/GBR) regeneration continues as till now none of the commercially available GTR/GBR membrane fulfils the desired criteria. Currently, a variety of new materials and ...
