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 ...
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 ...
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 ...
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 ...
In this work, we study synchronisation in power grids using a classical phase oscillator
model that can be thought of as a variant of the famous Kuramoto model for coupled
phase oscillators. In the recent literature, the ...
Mental synthesis is the human ability to purposefully form novel mental imagery by
combining memories of different modalities. The neuronal mechanisms that facilitate
this process remain poorly understood. Mental synthesis ...
The 2D crystal lattice graphene has attracted tremendous research interest due to its exceptional properties that provide interesting opportunities for many applications, including energy storage technologies. Graphene has ...
We report on first-principles density functional theory (DFT) calculations of interactions between extrinsic defects and intrinsic structural defects in silicene. Specifically, we investigate the stability, structural, ...
The understanding of the nuclear breakup dynamics at sub-barrier incident energies,
remains a hot subject in Nuclear Physics. In this dissertation, the breakup of the weaklybound
neutron-halo 11Be nucleus impinging on a ...
The structure, morphology, optical, and electrical characteristics of rare earth (RE) metal ions, few-walled carbon nanotubes (FWCNT) and zinc oxide (ZnO) nanocomposite for possible applications such as electron acceptor ...
