Molecular sensors for evaluating substandard anti-retroviral medication using surface-enhanced raman spectroscopy.
(2023)Africa has the highest number of people living with HIV and AIDS, with South Africa housing the largest Anti-retroviral treatment (ART) program in the world. In addition, the continent is troubled by the continuing ... -
Some topics in modelling South African COVID-19 epidemiological data.
(2023)The ongoing COVID-19 epidemic produces a wide variety of quality data, which can be analyzed using simple mathematical models inspired by statistical physics. We explore some underlying methods and apply them to the ... -
Application of machine learning techniques to the description of open quantum systems.
(2023)This work focuses on using classical machine learning (ML) models to study the quantum dynamics of excitation energy transfer (EET) within strongly coupled open quantum systems relevant to light harvesting complexes ... -
Avoidance of trappings in continual collapse of spherical stars.
(2019)In this dissertation we study the physical process of a spherically symmetric perfect uid experiencing a continuous gravitational collapse in concurrence with continuous radiating energy in an outward spacetime. Trapped ... -
The effects of traveling ionospheric disturbances on SuperDARN near range echoes.
(2022)Traveling Ionospheric Disturbances (TIDs) and Near Range Echoes (NREs) are both natural phenomena observed by SuperDARN High Frequency (HF) radars. This study presents for the first time observations of NREs in the lower ... -
The effect of metal nano-composites on the performance of thin film organic solar cells.
(2021)This thesis examines the role of plasmonic nano-particles in the fabrication of thin film organic solar cells (OSCs). Organic solar cells are made up of conducting polymers blend that are formed as ultrathin layers (a few ... -
Plasmon as a mechanism to improve performance of bulk-heterojunction organic solar cells.
(2022)Narrow optical absorption band of fullerene based organic photovoltaics (OPVs) is one of the challenges to produce efficient polymer based solar panels that compete with inorganic counter part. There have been efforts ... -
Pulsed laser ablation synthesis of silver nanoparticles with rapid ionophore derivatives for antivirus activities.
(2022)The world woke up to a deadly pandemic SARS Covid-19 that broke out of Wuhan, China in December 2019. Many drugs were proposed to help in treating this disease. However, at the time, few drugs showed potential effectiveness ... -
High-resolution geophysical imaging and characterization of severe landslides vicinities at South-Eastern Nigeria for uni-vario-seasonal degradation monitoring and civil engineering remediation.
(2021)This research work used high-resolution geophysical methods to explore the near surface of severe gully-erosion sites. The erosion that mesmerized the environment as landslides is the major landscaping challenge facing ... -
The synthesis and characterization of magnetic α-Fe₂O₃ and ϵ-Fe₂O₃ nanoparticles.
(2021)Abstract available in PDF. -
Biochemical-physical mechanisms of light-tissue interactions.
(2021)Optical tissue phantom samples simulating the optical properties of the human prostates and brain tissues were fabricated. The experimental set-up was designed to be cost-effective but reliable, allowing for convenience ... -
An investigation into the radioprotective potential of Costus afer and Drymaria cordata extracts on whole-body irradiated mice.
(2021)The need for effective and non-toxic radioprotectors has shifted researchers' attention to plants and natural products as an alternative to synthetic compounds. This study investigated the radioprotective potential of ... -
Development of a mathematical model to enable optimal efficiency of the indabuko lithium-ion battery.
(2020)Cathode materials are the foremost primary challenge for the vast scale application of lithium-ion batteries in electric vehicles and the stockpiles of power. Foreseeing the properties of cathode materials is one of the ... -
The effect of metal nano-composites on the performance of thin film organic solar cells.
(2021)This thesis examines the role of plasmonic nano-particles in the fabrication of thin film organic solar cells (OSCs). Organic solar cells are made up of conducting polymers blend that are formed as ultrathin layers (a few ... -
Investigation of IBMQ quantum device hardware calibration with Markovian master equation.
(2022)In the design of quantum technology, it is crucial to account for the quantum system interacting with its environment to understand the influence of thermal processes and design the devices to avoid e↵ects of relaxation ...
