Synthesis and characterization of zinc-doped magnetic nanoparticles for diagnostic studies
(University of the Western Cape, 2015)
In the present study we report the synthesis and characterization of iron oxide magnetic nanoparticles doped with zinc in an attempt to enhance the magnetic properties. The nanoparticles were prepared via the co-precipitation ...
Synthesis, characterization and physicochemical properties of platinum naboparticles on ordered mesoporous carbon
(University of the Western Cape, 2011)
In this study SBA-15 mesoporous silica template was synthesized and used as a sacrificial template in the preparation of ordered mesoporous carbon material. A chemical vapour deposition (CVD) technique using LPG or ...
The assessment of the bactericidal effect of green synthesized silver nanoparticles against a panel of infectious microorganisms
(University of the Western Cape, 2016)
The emergence of multiple drug resistant microorganisms poses a major threat to human life. These microorganisms have made the currently used antibiotics ineffective and therefore continue to thrive. Therefore, there is a ...
The interaction between 6 MV X-rays and p(66)/Be neutrons with spherical gold nanoparticles to induce cellular damage
(University of the Western Cape, 2016)
Despite the advances in therapies such as chemotherapy and radiotherapy, tumours have been shown to be resistant to the treatments. Gold nanoparticles (AuNPs) have been recognized as effective radiosensitizers of low energy ...
The effects of capping agents on the synthesis of magnetic-luminescent Fe₃O₄ -InP/ZnSe nanocomposite material
(University of the Western Cape, 2015)
Magnetic luminescent nanoparticles of an iron oxide (Fe₃O₄) superparamagnetic core and an indium phosphide/zinc selenide (InP/ZnSe) quantum dot shell are reported. The magnetic nanoparticles (MNP’s) and quantum dots (QD’s) ...
Development of a bismuth-silver nanofilm sensor for the determination of platinum group metals in environmental samples.
(University of the Western Cape, 2015)
Nowadays, the pollution of surface waters with chemical contaminants is one of the most crucial environmental problems. These chemical contaminants enter rivers and streams resulting in tremendous amount of destruction, ...
Graphene supported antimony nanoparticles on carbon electrodes for stripping analysis of environmental samples
(University of the Western Cape, 2015)
Platinum Group Metals (PGMs), particularly palladium (Pd), platinum (Pt) and rhodium (Rh) have been identified as pollutants in the environment due to their increased use in catalytic converters and mining in South Africa ...
Heavy and precious metal toxicity evaluation using a horseradish peroxidase immobilised biosensor
(University of the Western Cape, 2012)
Environmental pollution is always the hottest topic in public conversation and one of the most concerned aspects of human health. The thin film sputtered microelectrode devices have been developed to improve the quality ...
Synthesis of zinc oxide nanoparticles by a green process and the investigation of their physical properties
(University of the Western Cape, 2017)
Zinc oxide (ZnO) is a wide and direct semiconductor with a wurtzite crystal structure. Its
multifunctionality as the ideal candidate in applications such as blue-UV light emitting
diodes, transparent conducting oxide, ...
Synthesis and characterization of nanofluids for cooling applications
(University of the Western Cape, 2006)
Low thermal conductivity is a primary limitation in the development of energy-efficient heat transfer fluids that are required in numerous industrial sectors. Recently submicron and high aspect ratio particles (nanoparticles ...
