(University of Pretoria, 2018)Silicon and indium tin oxide (ITO) are the active components of the modern day devices. ITO is the most used transparent conducting material (TC) in smartphones and other touch panel devices, because the required properties ...
-
(University of Pretoria, 2016)Despite its favourability as a substrate in chemical vapour deposition (CVD), copper (Cu) substrate has a challenge of growing uniform large-area bilayer graphene films with continuous Bernal (AB) stacking. However, ...
-
(University of Pretoria, 2020-12-14)Synthesis of activated carbon from biomass waste has recently become the main focus for the majority of the scientific community. In this study, activated carbons derived from peanut shell waste and its molybdenum-based ...
-
(University of Pretoria, 2022)In this thesis, “Characterization and performance evaluation of electrodeposition synthesized cobalt-nickel layered double hydroxide and composites for high-efficiency hybrid capacitor applications”, an efficient binder-free ...
-
(University of Pretoria, 2021)Colourimetric indicators were prepared using anthocyanins, poly(vinyl alcohol) and cellulose nano-fibre by the electro-spinning technique. The indicator label containing 2000 ppm anthocyanin was found to be the optimal dye ...
-
(University of Pretoria, 2023)This Ph.D. work is based on the synthesis and characterization of activated carbon from cross-linked polymers and the enhancement of its electrochemical performance through heteroatoms and cobalt incorporation. These ...
-
(University of Pretoria, 2020)Sustainable, environmentally friendly, and renewable energy sources are urgently needed as concerns about carbon emissions and the depletion of fossil fuels are becoming worrying. It is vital to explore cost-effective ...

(University of Pretoria, 2015)The aim and objectives of this work are to optimize the synthesis of metal hydroxides - graphene foam (GF) composites using different configurations of graphene with a facile and environmentally friendly solvothermal ...
-
(University of Pretoria, 2013)Graphite and graphite composite materials are of great importance in various applications; however, they have been widely used in nuclear applications. Primarily in nuclear applications such, as a moderator where its primary ...
-
(University of Pretoria, 2012-07-16)The magnetic behavior of cubic B20 crystal structure FeSi thin film has been previously probed at macroscopic level using a magnetometer. The results revealed ferromagnetic state with significant hysteresis. This is contrary ...
-
(University of Pretoria, 2021-05-31)The study focuses on exploring ways to extract valuable metals from waste materials such as spent lithium-ion batteries (LIBs) and coal fly ash (CFA) and thus converting them into Metal-organic frameworks (MOFs) suitable ...
-
(University of Pretoria, 2018)In this study, the effect of the inclusion of a hydrothermal pre-treatment procedure and varying the mass ratios of the raw material and the activating agents on the electrochemical performance of laboratory-synthesized ...
-
(University of Pretoria, 2013)The Pebble Bed Modular Reactor (PBMR) is a high temperature graphite-moderated nuclear reactor that uses helium as a coolant. The triple coated (TRISO) particles contain enriched uranium oxide fuel which is coated with ...
-
(University of Pretoria, 2020-11-30)Vanadium disulphide/graphene foam composite samples with varying physical and electrochemical properties were synthesised through varying the mass of graphene in the composite. The optimized VS2/GF-100 mg exhibited superior ...
