TiO₂ nanotube based dye-sensitised solar cells
(University of the Western Cape, 2012)
The first report of a functioning photo-electrochemical solar cell in 1991 attracted a lot of interest from scientists and industrial groups. From an industrial point of view these so-called dye-sensitised solar cells ...
Vanadium dioxide nanocomposite thin film embedded in zinc oxide matrix as tunable transparent conductive oxide
(University of the Western Cape, 2013)
This project is aimed at fabricating a smart material. Zinc oxide and vanadium dioxide have received a great deal of attention in recent years because they are used in various applications. ZnO semiconductor in particular ...
Deposition and structural properties of silicon carbide thin films for solar cell applications.
(University of the Western Cape, 2014)
The growth of hydrogenated amorphous silicon carbide (a-SiC:H) thin films deposited by Hot- Wire Chemical Vapour Deposition (HWCVD) for solar cell applications has been studied. The films were characterized for structural ...
Physical properties of vanadium dioxide nanoparticles: application as 1-d nanobelts room temperature for hydrogen gas sensing
(University of the Western Cape, 2013)
Transition metal oxides magneli phases present crystallographic shear structure which is of great interest in multiple applications because of their wide range of valence, which is exhibited by the transition metals. The ...
The nature of the microjy source population
(University of the Western Cape, 2015)
The study of the faint radio universe and of its properties has recently become a very active field of research not only because of the much improved capabilities of the SKA pathfinders but also because of the need to ...
Magnetic substitution in CePt₂Si₂ and CeCu₅In Kondo lattice
(University of the Western Cape, 2013)
In the past few decades, the studies of f-electron materials have revealed unusual physical properties such as Fermi-liquid, non-Fermi-liquid behaviour at low temperatures, heavy- Fermion behaviour, valence fluctuation, ...
Gamma spectroscopy and lifetime measurements in the doubly-odd 194tl nucleus, revealing possible chiral symmetry breaking
(University of the Western Cape, 2013)
In the first experiment high spin states in 194Tl, excited through the 181Ta (18O, 5n) heavyion fusion evaporation reaction were studied using the AFRODITE array at iThemba LABS. The γ-γ coincidences, RAD ratios and linear ...
Electrical resistivity of the kondo systems (Ce1−xREx)In3, RE = Gd, Tb, Dy AND Ce(Pt1−xNix)Si2
(University of the Western Cape, 2008)
The present study investigates the strength of the hybridization by substituting Ce atom in Kondo lattice CeIn3 with Gd, Tb, and Dy and by changing the chemical environment around the Ce atom in substituting Pt with Ni in ...
Galaxy evolution and cosmology studies using luminous red galaxies
(University of the Western Cape, 2014)
There have been a number of attempts to measure the expansion rate of the Universe using age-dating of Luminous Red Galaxies (LRGs). Assuming that stars in LRGs form at the same time, age-dating of two populations of LRGs ...
Thermochromic properties of VO2 nano-coatings by inverted cylindrical magnetron sputtering
(University of the Western Cape, 2012)
Vanadium dioxide (VO2) films have been known as the most feasible thermochromic nano-coatings for smart windows which self control the solar radiation and heat transfer for energy saving and comfort in houses and automotives. ...
