(University of Pretoria, 2022)Metal organic frameworks (MOFs) have been used as electrochemical sensors owing to their high surface area and porosity. Unfortunately, the low conductivity and redox activity of MOFs limit their application in electrochemical ...
-
(University of Pretoria, 2022-02-25)The detection and quantification of cannabinoids within biological matrices are still required, despite the legalisation of cannabis use in South Africa. The development of a fit-for-purpose analytical method for the ...
-
(University of Pretoria, 2022)The ionization potential and electron attachment energy are fundamental properties of molecules and is core to a range of physical processes such as those in photovoltaics, electrochemistry, spectroscopy, etc. Ionization ...
-
(University of Pretoria, 2021)Molecular orbitals (MOs) are one of the most useful tools available for explaining and describing the electronic structure of a chemical system. These MOs are obtainable through different means, which falls under two ...
-
(University of Pretoria, 2021)Tautomeric and anionic forms of nucleic acids are potentially involved in mutations and replication and translational errors; however, research into the chemistry of deprotonated nucleobases is limited. This research focused ...
-
(University of Pretoria, 2022-07-11)Computational-based strategies have become of great significance in drug discovery, owing to their key contributions towards the development of new therapeutics. In various diseases, the overall lack of response to ...
-
(University of Pretoria, 2021)This dissertation details the investigation of the synthetic pathway of the antiretroviral drug, tenofovir, and its prodrug forms tenofovir disoproxil and tenofovir alafenamide, in attempt to develop a more efficient route ...
-
(University of Pretoria, 2021)Diesel exhaust emissions from vehicles have been receiving global attention, due to the potential human health and negative environmental effects associated with exposure to emitted pollutants. Air pollutants emitted by ...
-
(University of Pretoria, 2014-10)Please read abstract in article.
-
(University of Pretoria, 2022)Self-regulated learning (SRL), also defined as metacognitive, motivational, and behavioural active participation of students in their own learning process, has an influence on their academic success. This paper reports an ...
-
(University of Pretoria, 2021)Malaria continues to be a major infectious disease with 229 million cases reported in 2019 of which 94% occurred in the African region. Problems such as poor aqueous solubility, instability, toxicity and drug resistance ...
-
(University of Pretoria, 2021)In this project, a comprehensive review of existing and emerging technologies for the mitigation of PAH pollution in water was conducted. Furthermore, the status of antiretroviral drugs in African surface water, toxicological ...
-
(University of Pretoria, 2021)Hybrid halide perovskites have received much attention over the past two decades due to their realisation in optoelectronic applications. In this study, hybrid halide alkali metal perovskites that contained either piperazinium ...
-
(University of Pretoria, 2021)Spectroscopes are practical tools that show the quantization of emitted light from excited elements and compounds, as well as helping students understand modern models of the atom and appreciate the unique identifying power ...
-
(University of Pretoria, 2020)Electron (de)localization is notoriously difficult to study. However, it is critically important for fundamental understanding of various photophysical and photochemical processes, including those that occur during ...
-
The origin of electron density accumulation within CH,HC contacts in biphenyl : a theoretical study (University of Pretoria, 2021)The primary focus of this work is the investigation into the nature and origin of the electron density between the ortho-hydrogens in the higher energy, planar transition state of biphenyl. This interaction has been the ...
-
(University of Pretoria, 2014)Phosphogypsum is a waste generated during the production of wet phosphoric acid from phosphate rocks. Numerous studies have attempted to find applications for phosphogypsum, but its composition is generally limiting its ...
-
(University of Pretoria, 2013)This dissertation describes the electrochemical properties of nanocarbons (multiwalled carbon nanotubes (MWCNTs) and graphene oxide (GO)) incorporated with manganese dioxide (MnO2) and metallotetrapyrazinoporphyrazines ...
-
(University of Pretoria, 2014)Mycolic Acids (MAs) are long chain α-alkyl-β-hydroxy fatty acids that form part of the cell wall of Mycobacterium species and a few other genera. They play an important role in steering the host-pathogen relationship to ...
-
(University of Pretoria, 2013)Palladium-based nano-alloys are well-known for their unique electrocatalytic properties for direct alcohol alkaline fuel cells (DAAFCs). This dissertation describes, for the first time, the synthesis of a novel ternary ...
