Optical modeling of amorphous and metal induced crystallized silicon with an effective medium approximation
Muller, Theophillus Frederic George (University of the Western Cape, 2009)In this thesis we report on the metal-mediated-thermally induced changes of the structural and optical properties of hydrogenated amorphous silicon deposited by hot-wire CVD, where aluminium and nickel were used to induce ... -
Proton conductivity stability studies by modelling
Square, Lynndle Caroline (University of the Western Cape, 2016)In this thesis, some of the challenges experienced by high temperature polymer electrolyte membrane fuel cells are explored through material modelling techniques. A very important aspect for a fuel cell is that it should ... -
Spectrally selective AlXOY/Pt/AlXOY solar absorber coatings for high temprature solar-thermal applications
Nuru, Zebib Yenus (University of Western Cape, 2014)The limited supply of fossil hydrocarbon resources and the negative impact of CO2 emission on the global environment dictate the increasing usage of renewable energy sources. Concentrating solar power (CSP) systems are the ... -
Structural and gas sensing properties of TiO₂-based (Sn, Mg) nano-structures induced by mechanical milling and annealing
Bolokang, Amogelang Sylvester (University of the Western Cape, 2015)Titanium oxynitride has attracted research interest for the fact that it is a bioactive non-toxic material. It is suitable for surface coating of biomaterials and in other applications such as anti-reflective coatings, ... -
Structure property relationship and thermal stability of organic photovoltaic cells
Motaung, David Edmond (University of the Western Cape, 2010)In this thesis, regioregularpoly( 3-hexylthiophene) (rr-P3HT) polymer was used as a light absorption and electron donating material, while the C60 fullerene and its derivative [6,6]-phenyl C61-butyric acid methyl ester ... -
Synthesis of bimetallic immiscible alloy nanoparticles through green and gamma radiolysis approaches for environmental remediation applications
Noukelag, Sandrine Kamdoum (University of the Western Cape, 2022)The synthesis of bimetallic immiscible alloy nanoparticles (NPs) using versatile routes, is a major concern since physio-chemical methods are not environmentally benign. Breaking down the immiscibility would generate NPs ...
