-
(University of Pretoria, 2019)South African-grown plants and their possible skin care benefits are increasingly gaining interest. For skin care applications, stable carrier formulations must be developed to incorporate extracts of these plants. Many ...
-
(University of Pretoria, 2019)Malaria parasite infects more than 200 million people and about 435 000 succumb to the illness annually (WHO, 2019). Victims are mostly young children and pregnant women. It is transmitted by the bite of the infected female ...
-
(University of Pretoria, 2019)Southern Africa is characterised as a region of moderate seismicity with several instances of both natural seismicity and mining-related seismicity occurring within the last century. Evaluating the performance of a structure ...

-
(University of Pretoria, 2018)Amoss is a generic equation-orientated stochastic simulation platform speci cally designed to facilitate the development and simulation of stochastic models, using Sasol's in-house MOSS methodology. In the current situation ...
-
(University of Pretoria, 2018)The Fluorochemical Expansion Initiative (FEI) program was implemented to encourage the local beneficiation of South Africa’s abundant fluorspar resources for the benefit of the economy. Fluoropolymer production was identified ...
-
(University of Pretoria, 2018)This dissertation details research aimed at the separation of Zr and Hf in the tetrafluoride form. Separation of ZrF4 and HfF4 was achieved using sublimation followed by desublimation. The separation involves the sublimation ...
-
(University of Pretoria, 2018)Rapid prototyping techniques are quickly advancing to become market leading manufacturing techniques in terms of: product availability, cost effectiveness and environmental impact. In addition, they are also rendering ...
-
(University of Pretoria, 2018)Numerous modi cations were made to simple basin solar stills with the aim to improve the performance of the stills and develop an understanding of the operation of the system. The changes were focused on reducing energy ...
-
(University of Pretoria, 2018)Finding the source of a disturbance in complex systems such as industrial chemical processing plants can be a difficult task and require a significant amount of engineering hours. In many cases, a systematic elimination ...
-
(University of Pretoria, 2019)The ability to reduce Cr(VI) to Cr(III) has been discovered in multiple species of bacteria. This ability has manifested as either a detoxification strategy to ensure survival in Cr(VI) rich environments, or as a metabolic ...
-
(University of Pretoria, 2018)Environmental sustainability has become a leading discussion in the world, coupled with a quest to minimise severe environmental pollution. The chrome mining and ferrochrome processing industrial revolution has contributed ...
-
(University of Pretoria, 2018)Alumina particles were successfully coated with silicon carbide (SiC) layers in a microwave plasma-assisted spouted bed reactor. Methyltrichlorosilane (MTS) was used as precursor for the SiC deposition reaction, and argon ...
-
(University of Pretoria, 2017)This research aimed to characterise the physico-chemical and structural properties of rectorite from a local deposit, the Beatrix Gold Mine in South Africa and to investigate its unique material properties. The ultimate ...
-
(University of Pretoria, 2017)The nature of letsoku and related clayey soils, traditionally used by indigenous Southern African communities for a wide range of purposes, was explored. Thirty-nine samples were collected from Botswana, Lesotho, Swaziland, ...
-
(University of Pretoria, 2018)The ability of a lubricating oil to reduce friction in mechanical surfaces which are in relative sliding motion depends on the base oil behaviour. Previous studies have demonstrated that temperature has a significant ...
-
(University of Pretoria, 2017)A series of fluorinated LiCoO2 compounds, LiCoO2−xFx with x = 0.05 − 0.65, were synthesised by both a sol-gel and a solid-state method. The sol-gel method utilises LiNO3 and Co(NO3)2.6H2O as Li and Co sources respectively, ...
-
(University of Pretoria, 2018)A promising energy harvesting technique involves the use of thermal nanofluids, capable of collecting solar UV/visible radiation and storing it as latent heat in phase change materials (PCM), i.e. molten salts. Carbon-based ...
-
(University of Pretoria, 2018)This report determines the influence of spectral beam splitting on the temperature, maximum power and efficiency of a polycrystalline silicon cell under concentrated light. The PV cell was exposed to wavelengths ranging ...
-
(University of Pretoria, 2016)A laboratory process exists for the extraction of kafirin protein from sorghum grain in order to form kafirin encapsulating microparticles. This laboratory process extracts approximately 2 g of protein and takes in excess ...
