Optical and microarray silver-gold based sensors for the detection of e.coli 0157:h7 in seawater
(University of the Western Cape, 2021)
Recently researchers reported that nanoparticles functionalised through chemical methods possess risks to the environment and to the human health since they use hazardous chemicals and produce toxic waste. The increasing ...
Photovoltaic and gas sensing applications of transitional metal nanocomposites of poly(3-hexylthiophene)-titanium dioxide
(University of Western Cape, 2021)
This thesis starts with the reviewing of studies on the loading of noble metals and nanostructured metal oxides into bulk heterojunction organic solar cell device architectures. The reviews focused on the innovative ...
Synthesis of DMSO based silver nanoparticles for application in wound healing
(University of Western Cape, 2021)
Silver nanoparticles (AgNPs) apart from being chemically significant, have shown a lot of health benefits, the most studied being their anti-bacterial and anti-inflammatory properties. These biological properties can be ...
Photovoltaics of selenide kesterite doped with nanoscopic iron and cerium oxyselenides
(University of Western Cape, 2021)
As the demand for energy is constantly increasing, researchers are looking at various methods of energy production. Following the rise of solar energy becoming a major player, researchers are looking at kesterite materials, ...
Metal modified mesoporous ZSM-5 as catalysts for the oligomerization of 1- hexene
(University of Western Cape, 2021)
The use of diesel engines in vehicles and heavy machinery throughout the world has been
slowly increasing in the past few decades. This has led to high demand for diesel and
gasoline with high octane number. Diesel and ...
Hydrothermal synthesis of hierarchical ZSM-5 with different Si/Al ratio and their evaluation as catalysts in the catalytic cracking of hexane
(University of Western Cape, 2021)
Ethylene and propylene are greatly used for their importance as feedstocks for producing useful materials. Due to rise in prices and the demand of ethylene and propylene, the need to increase the selective production of ...
Microwave synthesis of the Schiff base metal-ligand complexes with Cu and Ni centres
(University of Western Cape, 2021)
Nitric oxide (NO) plays a vital role as a biological messenger in biological systems. However, NO detection and quantification have always posed significant complications. There is, therefore, a need to develop new materials ...
Isothermal and non-isothermal comparative study of Zn-sn system using real-time RBS
(2021)
Solid-state reactions of bi-metallic systems can be driven or activated by various external
stimuli like pressure, energetic photons, energetic charged particles or heat. For an example,
high pressure torsion can be ...
The role of surface modified TiO2 nanoparticles for application in 68Ge/68Ga generator systems and the use of molecular imprinted polymers for 68Ge breakthrough control
(University of Western Cape, 2021)
Titanium dioxide (TiO2) has potential as an adsorbent within the 68Ge/68Ga generator context. To function effectively, three basic requirements are required: optimum 68Ga elution efficiency, stability and removal of the ...
Polypyrrole supports for direct alcohol fuel cells.
(University of Western Cape, 2021)
Anode catalysts are one of the key components of direct alcohol fuel cells (DAFCs). They play a huge role in the alcohol oxidation reaction (AOR) that occurs on the anode side. Palladium (Pd) supported on carbon material ...
