Synthesis, characterization and catalytic application of carbonyl complexes of molybdenum and tungsten in epoxidation of some alkenes
(University of the Western Cape, 2010)
In this thesis we describe the synthesis of several carbonyl complexes of molybdenum and tungsten, compounds (Cl-ClO). The compounds Cl- C4 are zero valent carbonyl complexes containing N-base ligands prepared by following ...
L-Cysteine-Capped Indium Telluriselenide Quantum Dot Aptasensor for Interferon-Gamma TB Biomarker
(University of the Western Cape, 2018)
Tuberculosis (TB) is one of the major infectious diseases that affect the health of people all
over the world. South Africa is one of the countries that account for most of the TB cases; it
is the leading cause of death ...
Synthesis and characterisation of high silica zeolites with MOR and MFI framework type from South African coal fly ash.
(University of the Western Cape, 2019)
High-silica zeolites are porous, aluminosilicate materials known for high thermal stability;
making these materials favourable for application in various industrial processes involving
elevated temperatures. The synthesis ...
Hydrogeomorphic controls on the longitudinal distribution and dynamics of reed beds in non-perennial river systems, Western Cape, South Africa.
(University of the Western Cape, 2019)
There has been a growing interest in the role of interactions between vegetation and
geomorphology in shaping fluvial environments, from evolutionary to modern-process
timescales. However, much of this work has mainly ...
Supercapacitor development from transition metal-integrated spinel manganese oxide-carbon nanotubes composite materials
(University of the Western Cape, 2019)
Supercapacitors are electrochemical energy storage devices, much like Li-ion batteries, that
have expeditiously been improved over the years through extensive research conducted in
material sciences and nanotechnology. ...
Microfluidic paper based electrochemical sensing devices
(University of the Western Cape, 2019)
Microfluidic paper based electrochemical sensing devices (μPEDs) provides a new way for
point of care testing (POCT). μPEDs offer an inexpensive, portable, easy to use technology too
monitor the environment and diagnose ...
Sustainable synthesis of BEA zeolite from fly ash-based amorphous silica
(University of Western Cape, 2019)
Power generation in South Africa depends majorly on the combustion of coal and the
increasing demand for energy due to industrialisation and population growth signifies the
continuous consumption of coal. During this ...
Electrochemical ochratoxin a immunosensors based on polyaniline nanocomposites templated with amine- and sulphate-functionalised polystyrene latex beads
(University of the Western Cape, 2010)
Polyaniline nanocomposites doped with poly(vinylsulphonate) (PV-SO3) and nanostructured polystyrene (PSNP) latex beads functionalized with amine (PSNP-NH2) and sulphate ((PSNP-OSO3) were prepared and characterised for use ...
Synthesis and characterization of micro- and mesoporous materials for low temperature selective catalytic reduction of nitrogen oxides
(University of the Western Cape, 2011)
In summary, it has been shown during this study that bimetallic Fe and Mn containing catalysts can be prepared by wet impregnation and not by ion exchange because of the competition between two different metals at different ...
Electrochemical characterization of nanostructured SnO2 and TiO2 for potential application as dielectric materials in sulfonated-polyaniline based supercapacitors
(University of the Western Cape, 2010)
In this research project, nanostructured composites based on Tin dioxide (SnO2) and Titanium dioxide (TiO2) with poly-4-styrene sulfonic acid (PSSA) doped polyaniline (PANI) conducting polymer has been investigated based ...
