Growth and characterization of FeSi nanowires by chemical vapor deposition for gas sensing applications
(University of the Western Cape, 2014)FeSi nanowires were synthesized via a chemical vapor deposition method. Anhydrous FeCl3 powder in this case served as the Fe source and was evaporated at a temperature of 1100oC to interact with silicon substrates which ... -
An hi study of the nearby dwarf galaxy ic 4710
(University of Western Cape, 2021)This work aims to study the dark matter content of the nearby (7.38 Mpc) dwarf galaxy IC 4710 using the HI line observations from the Australia Telescope Compact Array (ATCA). We produce the rst interferometric maps of ... -
High resolution gamma-spectroscopy of environmental samples
(University of the Western Cape, 2019)In this study, a comparison has been made between the available commercial software package Genie 2000 developed by Canberra and Virtual Gamma Spectroscopy Laboratory (VGSL) developed by the Radionuclide Development Unit ... -
Hot-wire chemical vapor deposition of silicon nitride thin films
(2013)Amorphous silicon nitride (a-SiN:H) thin films has a multitude of applications, stemming from the tunability of the material properties. Plasma enhanced chemical vapour deposition (PECVD) is the industrial workhorse for ... -
Hot-wire chemical vapour deposition of carbon Nanotubes
(University of the Western Cape, 2006)In this study we report on the effect of the deposition parameters on the morphology and structural properties of CNTs, synthesized by means of the hot-wire chemical vapour deposition technique. SEM, Raman and XRD results ... -
Hydrogen storage capacity of the Ti-Pd multilayer systems
(University of the Western Cape, 2020)Hydrogen has high energy density and it is regarded as the future energy carrier. Hydrogen can be stored as a gas in high-pressure cylinders, as a liquid in cryogenic tanks and as a solid in metal hydrides. The storage of ... -
Hydrogen storage in Ti-based coatings and Ti6Al4V alloy
(University of the Western Cape, 2016)Hydrogen has been regarded as an ideal energy carrier for future, it can be stored as a liquid in cryogenic tanks, a gas in high pressure cylinders and as solid in metal hydrides. Hydrogen storage in metal hydrides is of ... -
Hydrogenisation of metals
(University of the Western Cape, 2013)Transition metals are a group of metals which are light in weight and have high hydrogen solubility. Their interaction with hydrogen is exorthermic and this phenomenon makes them “ideal” candidates for various applications ... -
Impact of different chemical synthesis techniques on the structural and photoluminescence properties of Zn4B6O13: RE3+ (where RE3+ = Sm3+, Eu3+, and Dy3+) nanophosphors
(University of the Western Cape, 2023)Different chemical synthesizing techniques, such as sol-gel, combustion, and solid-state reaction routes, offer the unique possibility of generating high-purity nanophosphors with different morphologies. In this project, ... -
The impact of environment and mergers on the H I content of galaxies in hydrodynamic simulations
(University of the Western Cape, 2015)We quantitatively examine the effects of merger and environment within a cosmological hydrodynamic simulation. We show that our simulation model broadly reproduces the observed scatter in H I at a given stellar mass as ... -
In-situ measurements of radon concentrations in soil gas at a site on the Cape Flats
(University of the Western Cape, 2007)Measurements of radon (222Rn) concentration in soil gas are routinely used to locate geological fault zones. This study was undertaken to investigate the systematic effects that influence radon soil-gas measurements, in ... -
Inclusive (p, α) and (p,³He) cross sections induced by 100 MeV protons on ⁴⁰Ca
(University of the Western Cape, 2006)Alpha clusteri ng in nuclei is studied with quasi - free knockout reactions. A beam of 100 MeV polarized protons was used in the quasi-free knockout reaction 40 ~a( p,p' a)36 Arat iThemba LABS. While the scattered protons ... -
The influence of maternal nicotine exposure on neonatal rat trachea development and alveoli status
(University of the Western Cape, 2000)The aim of this study was to determine the effect of maternal nicotine exposure on the status of the rat tracheal development as well as the rat lung of 7 to 42 day old offspring. Wistar dams were injected subcutaneously, ... -
Influence of synthesis method on structural
(Springer, 2023)This contribution reports on the development of two versatile and efcient methods, namely the green and gamma radiolysis for Fe-Ag nanoparticles (NPs) synthesis, characterization, and further their growth inhibition potential ... -
Infrared-bright galaxies in the millennium simulation and Sunyaev Zeldovich effect contamination
