In this work, SiO2, MWCNTs, MWCNTs:SiO2, MWCNTs-TiO2, and MWCNTs:TiO2:SiO2
nanomaterials were synthesized and characterized by the use of different techniques to
ascertain novelty of the nanomaterials and also to establish ...
Experimental X-ray production cross sections (i.e. probability of X-ray generation in a target by an incoming MeV ion) are useful not only for fundamental ion beam – matter interaction studies, but also for the development ...
This study addresses the use of visual aids in teaching geometry to enhance learners’ learning experience. This qualitative phenomenological study draws from Duval’s theory of semiotic representation which emphasises the ...
In the current project, GO was synthesized and functionalized with gold and iron oxide
nanoparticles. Several characterization techniques were performed to study the change
in the microstructural, electronic, electrical ...
The pharmaceutical industry continues to face challenges with properties of drugs like poor solubility, limited bioavailability and insufficient stability of active pharmaceutical ingredients (APIs), which collectively ...
We have synthesised graphene oxide (GO) using Hummer’s method which was further reduced (rGO) by hydrazine hydrate. We used the reverse micelle process to functionalise graphene oxide (GO) to synthesise P-GO and its ...
Crystalline silicon (Si) of different concentration types was implanted with Aluminium (Al) and Zinc (Zn) at the energy of 160 keV to the fluence of 1.0 1017 ions cm-2. Different material characterization techniques were ...
Vanadium oxide (VO2) is the archetype parent material for thermochromic smart window
and smart insulation for thermal control in buildings. VO2 shows a metal-insulator transition
(MIT) at a critical temperature ( cT ) ...
Using an ion implantation method, crystalline silicon (Si) of different concentration types (n-, p-, and i-types) was doped with iron (Fe) and cadmium (Cd) metals. Energy dispersive X-ray spectroscopy (EDS), X-ray diffraction ...
Experimental X-ray production cross sections (i.e. probability of X-ray generation in a target by an incoming MeV ion) are useful not only for fundamental ion beam – matter interaction studies, but also for the development ...
Chemical compounds categorised as natural products are diverse, with many classes such as terpenoids, steroids, alkaloids, peptides, and polyketides. Marine natural products encompass a wide array of chemical compounds ...
The work presented here is aimed at determining the stopping force of heavy ions in pure metallic foils using time of flight spectrometry and comparing the data obtained from experiments with data obtained from predictive ...
In this work, we have synthesized ultra-nano-crystalline diamond (UNCD) thin films with average thickness ∼200 nm on n-type mirror polished silicon (100) substrates using microwave plasma enhanced chemical vapour deposition ...
Conventional inorganic semiconductors such as silicon, germanium and gallium arsenide have been the backbone of the semiconductor industry over the past few decades. In recent years, organic electronics have attracted ...
Rutherford backscattering spectrometry and elastic recoil detection analysis measurements were used to characterize silicon material in order to establish the amount and the depth profile of niobium implanted in the bulk ...
The dissertation presents and compares the alternative methods that can be used to quantify high quality global horizontal irradiance (GHI) in areas with sparse in-situ radiometric measurements like South Africa. This was ...
In this work, Schottky diodes were fabricated on undoped and niobium-doped n-silicon (n-Si).
Niobium (Nb) doping was achieved by ion implantation at 160 keV to a fluence of 3 × 1015
ion.cm-2. The diodes were characterized ...
Poor mathematics performance is a global issue, including in South Africa, with a reported decline in skills worldwide Berisha et al. (2024). Learners struggle with understanding algebraic fractions, which are essential ...
The present work examined the occurrence of efavirenz, ibuprofen, naproxen, sulfamethoxazole, and trimethoprim in wastewater, sewage sludge, river water, estuaries, seawater, garden soil, and vegetables. This was achieved ...
Let L be a completely regular frame and RL be the ring of real-valued continuous functions
on L. In this dissertation, we will study the maximal ideals and prime ideals of the ring RL
which were described by Dube in [20] ...
