(University of the Western Cape, 2007)The overall aim of this thesis was to prepare nanostructured more processable heteronuclear sulphonated polyanyline nanocomposites with electroconductive properties suitable for applications in biosensors. The sulphonated ... -
Synthesis, optical and morphological characterization of pbse quantum dots for diagnostic studies: a model study
(University of the Western Cape, 2013)In this study PbSe quantum dots (QDs) were successfully synthesized via the organometallic and aqueous routes. Optical characterization was carried out using photoluminescence (PL) spectroscopy, structural and morphological ... -
Synthesis, spectroscopic characterization, and cyclic voltammetry studies for salicylaldehyde schiff base ligands and their copper (ii) salicylaldimine compounds
(University of the Western Cape, 2022)Schiff base compounds are a significant class of ligands in coordination chemistry which have been applied widely as they are precise and versatile towards different metal salts. These compounds could be commonly chelating ... -
Synthetic strategies for denatured cytochrome-c analogues towards analytical reporting of NOx species
(University of the Western Cape, 2019)Nitric oxide (NO) plays a key role as biological messenger in the biological system, however detection and quantification thereof has always posed significant problems. NOx is a principal constituent of air pollutants. ... -
Tellurium attenuation of kesterite band-gap for improved photovoltaic efficiency
(University of the Western Cape, 2019)Tellurium is a member of the chalcogen group in the periodic table and is known to be a better semiconductor material when compared to sulfur and selenium. By introducing tellurium into the kesterite structure there would ... -
Tellurium selenide-gadolinium tungsten oxide quantum dot material for supercapacitor
(University of Western Cape, 2022)Renewable energy has become the main alternative solution to the “energy crisis” the world is faced with. A supercapacitor is one of the energy storage devices capable of storing and releasing energy at a higher rate ... -
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 ... -
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 ... -
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) ... -
