Thermochemical Storage and Lithium Ion Capacitors Efficiency of Manganese-Graphene Framework
(University of the Western Cape, 2018)Lithium ion capacitors are new and promising class of energy storage devices formed from a combination of lithium-ion battery electrode materials with those of supercapacitors. They exhibit better electrochemical properties ... -
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. ... -
Thiolato schiff base complexes of nickel and palladium as mesogens and molecular wires
(University of the Western Cape, 2003)Thermal analysis data of compounds A, C, F and I established that they were nonmesogenic while E and G were found to be mesogenic. The lack of mesogenic behaviour of A could be attributed to hydrogen bonding. The ... -
Three dimensional thermal modelling of high temperature proton exchange membrane fuel cells in a serpentine design
(University of the Western Cape, 2010)The aim of my work is to model a segment of a unit cell of a fuel cell stack using numerical methods which is classified as computational fluid dynamics and implementing the work in a commercial computational fluid dynamics ... -
Three-dimensional structure of a type III glutamine synthetase by single particle reconstruction
(University of the Western Cape, 2007)This study represents the first structural investigation of any type III glutamine synthetase (GS). The GS, GlnA, from the medically important opportunistic human pathogen Bacteroides fragilis was studied with a view to ... -
Throughput of UWC students who did at least one semester of third-year statistics
(University of the Western Cape, 2005)This study explored the completion rates (the number of years a student takes to complete a degree) of graduates at the University of the Western Cape. Differences between students who finished their studies in the prescribed ... -
Throughput of UWC students who did at least one semester of third-year Statistics
(University of the Western Cape, 2005)The study explores the completion rates (the number of years a student takes to complete a degree) of graduates at the University of the Western Cape (UWC) in South Africa. The graduates in the study all did at least one ... -
Tin Catalyst preparation for Silicon Nanowire synthesis
(University of the Western Cape, 2018)Solar cells offer SA an additional energy source. While Si cells are abundantly available they are not at an optimal efficiency and the cost is still high. One technology that can enhance their performance is SiNW. ... -
Tin-oxide thin films by thermal oxidation
(University of Western Cape, 2021)Tin dioxide (SnO2) thin films are a worthy candidate for an electron transport layer (ETL) in perovskite solar cells, due to its suitable energy level, high electron mobility of 240 cm2 v-1 s- 1, desirable band gap of ... -
TiO2 nanotube based dye- sensitised solar cells
(University of Western Cape, 2012)This work investigated the synthesis of Al2O3-coated TiO2 nanotubes via the anodisation technique for application in DSCs. TiO2 nanotube arrays with an average length of 15 μm, diameter of 50 nm and wall thickness of 15 ... -
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 ... -
Titanium compounds and plant growth
(University of the Western Cape, 2001)The effect of titanium compounds on the growth of tomato plants, Lycopersicum esculentum (cultivar Floridade), was studied under greenhouse conditions. Aqueous suspensions (TiO2) and solutions (complexes of titanium (IV) ... -
Tonic immobility in two species of Southern African catsharks
(University of Western Cape, 2020)Tonic immobility (TI) can be defined as an unlearned behavioural response described by a physical state of immobility. This behaviour can last from a few seconds up to several hours. Tonic immobility in sharks has not been ... -
Topogenous orders and their applications on lattices
(University of the Western Cape, 2024)In his influential book, [Cs´a63] A. Cs´asz´ar developed the well-known theory of syntopogenous ´ structures on a set. His intention was to create a comprehensive framework that simultaneously encompasses the study of ... -
Topogenous Structures on Categories
(University of the Western Cape, 2016)Although the interior operators correspond to a special class of neighbourhood operators, the closure operators are not nicely related to the latter. We introduce and study the notion of topogenous orders on a category ... -

Toward Authentication Mechanisms for Wi-Fi Mesh Networks
(University of the Western Cape, 2011)Wi-Fi authentication mechanisms include central authentication, dynamic and distributed authentication and some encryption methods. Most of the existing authentication methods were designed for single-hop networks, as ... -
Toward best management practices for the growth of the abalone Haliotis midae Linnaeus on a commercial South African abalone farm
(University of the Western Cape, 2008) -
Towards a chereme based dynamic South African sign language gesture recognition system
(University of the Western Cape, 2007)Hand gestures are a natural and intuitive way of human to human communication. Motivated by the achievements made towards automatic speech recognition, and by the ease with which people sign, many researchers started ... -
Towards a classification system of significant water resources with a case study of the Thukela river
(University of the Western Cape, 2005)The increasing demand for water to provide for South Africa's growing population has resulted in increasing pressure being placed on the country's limited water resources. Water developments however cannot be undertaken ...
