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 ...
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) ...
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 ...
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, ...
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, 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 ...
Synthesis and characterization of iron oxide nanoparticles embedded on various polymers
(University of the Western Cape, 2018)
During the course of this study iron oxide nanoparticles, which have been researched for drug-targeted delivery, were synthesised via the co-precipitation method and characterised using various methods. This study focused ...
Synthesis, characterization and anticancer effects of quantum dots in neuroblastoma and glioblastoma cell lines
(University of the Western Cape, 2018)
Introduction: Nanoparticles (NPs) are gaining increased popularity for cancer treatment,
especially the multifunctional nanoparticles like Quantum dots (QDs) which have a wide range of
applications in nanotheranostics, ...
Multi-component Platinum Group Metals for the methanol electro-oxidation process
(University of the Western Cape, 2018)
The purpose of this study was to develop a high performance-lower cost catalyst
to be applied in Direct Methanol Fuel Cells (DMFC). The study also aimed to
prepare plurimetallic supported platinum (Pt), platinum-ruthenium ...
