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 ...
Development of heterostructured tin oxide nanocatalysts for the synthesis of bio-based maleic acid
(University of Western Cape, 2021)
Maleic acid (MA) is a key intermediate for the synthesis of polyester resins, surface coatings, lubricant additives, plasticizers, copolymers, pharmaceuticals and agricultural chemicals. The current industrial production ...
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 ...
Method development for selective recovery of rare earths elements from phosphogypsum waste
(University of Western Cape, 2021)
The need for rare earth elements (REEs) in current technologies has motivated countries with high imports dependency to search for alternatives sources. Several studies have been carried out to investigate the feasibility ...
Extraction, fractionation, nanoparticles formulation, and antimicrobial activity of lipids from black soldier fly larvae
(University of Western Cape, 2021)
Hermetia illucens (Diptera: Stratiomyidae) known as the black soldier fly (BSF) is an efficient ecological organic waste decomposer. Its larvae grow through six larval instars on a variety of decomposing organic substrates ...
Dehydrogenation of alkanes using sulfided metal catalysts
(University of Western Cape, 2021)
Light olefins are some of the main raw materials for the petrochemical industry. With the rise in oil prices and increasing demand for olefins, there is an increasing interest in finding cheaper alternatives for processes ...
