Synthesis and characterization of rhenium (vii) and rhuthenium (ii) dendritic catalysts: oxidative cleavage and epoxidation of alkenes
(2012)
Herein we report the successful synthesis of a class of stable and flexible Schiff-base chelators capable of coordinating both ruthenium (II) and rhenium (VII) and which would be catalytically active for oxo-transfer ...
Electrochemical characterization of platinum based catalysts for fuel cell applications
(University of the Western Cape, 2012)
Fuel cells convert chemical energy from a fuel into electricity through chemical reaction with oxygen. This possesses some challenges like slow oxygen reduction reaction (ORR),
overpotential, and methanol fuel cross over ...
Polyamic acid composites for multiiple sensing applications in complex sample matrices
(2013)
Polyamic acid-polypyrrole (PAA/PPy) composite films were prepared and characterised for the use as conducting platforms in the design of biosensor systems. The thin films were synthesised by electrochemical method from a ...
Polyanilino-graphene oxide intercalated with platinum group metal nanocomposites, for application as novel supercapacitor materials
(University of the Western Cape, 2014)
Supercapacitors are one of the important subjects concerning energy storage which has proven to be a challenge in this country. Currently, the electrodes of most commercial supercapacitor are made of carbon which is known ...
Metal nanoparticle modified polysulfone membrane for water treatment
(University of the Western Cape, 2013)
Membrane separation processes have been widely applied in the treatment of wastewater with polysulfone (PSF) polymer membrane being the most frequently used in ultrafiltration of wastewater due to its chemical and structural ...
Optimisation of a microfluidic device for the pre-concentration and size separation of cell free foetal DNA from maternal plasma by capillary electrophoresis
(University of the Western Cape, 2012)
The discovery of cell free foetal DNA (cffDNA) in 1997 allows for the combination of accuracy as well as non-invasiveness for prenatal diagnosis. This non-invasive genetic test requires only a maternal blood sample from ...
Electrodeposition of multi-valent metal oxides at 1-methyl-3-octylimidazolium bis(trifluoromethylsulfonyl) imide ionic liquid - carbon paste electrode
(University of the Western Cape, 2012)
A study on carbon paste electrode (CPE) materials containing 1-methyl-3-octylimidazolium bis (trifluoromethylsulfonyl) imide [MOIM[Tƒ2N] – a hydrophobic room temperature ionic liquid (IL) - is reported. CPEs with (a) the ...
Electrochemical immunosensor based on cyclodextrin supramolecular interactions for the detection of human chorionic gonadotropin
(University of the Western Cape, 2012)
Glucose oxidase (GOx) and horseradish peroxidase (HRP) are important enzymes for the development of amperometric enzyme linked immunosensors. The selectivity of each enzyme towards its analyte deepens its importance in ...
Liquid-liquid interface ion-transfer amperometric sensors for tenofovir as a model nucleoside/nucleotide anti-retroviral drug
(University of the Western Cape, 2014)
Amperometric sensors for Tenofovir, a model nucleotide/ nucleoside reverse transcriptase inhibitor ARV drug, were studied based on the principle of ion-transfer electrochemistry at the membrane-stabilized oil/ water interface ...
