Development of platino-iridium/ruthenium telluride nanoalloy electrode systems for possible application in ammonia fuel cell
(University of the Western Cape, 2015)
South Africa is undergoing a serious consideration of hydrogen economy in an effort to develop safe clean and reliable alternative energy sources for fossil fuels. Ammonia is one of the promising candidates due to its low ...
Chemistry and speciation of potentially toxic and radioactive elements during mine water treatment
(University of the Western Cape, 2012)
Mine water poses a serious environmental challenge and contains elements such as Fe, Al, and Mn in potentially toxic concentrations. The major anion in mine water is sulphate. The complexity and diversity of mine water ...
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, ...
Synthesis and characterization of new adsorbents for CO2 capturing
(University of the Western Cape, 2014)
Carbon dioxide emissions have become a major concern as they are one of the contributing factors to the “green-house” effect. Recently, much effort has been put into separating carbon dioxide (CO2) from flue gases linked ...
Production and evaluation of a TiO2 based 68Ge/68Ga generator
(University of the Western Cape, 2014)
68Ge/68Ga generators rely on metal oxide, inorganic and organic sorbents in order to prepare radionuclides useful for clinical applications. The requirements for 68Ge/68Ga generators are that the 68Ga obtained from the ...
Nanostructured light weight hydrogen storage materials
(University of the Western Cape, 2012)
The main objective of this study was to advance kinetic performances of formation and decomposition of magnesium hydride by design strategies which include high energy ball milling in hydrogen (HRBM), in combination with ...
Structural investigation of the natural products composition of selected South African seaweeds.
(University of the Western Cape, 2014)
Recently, a great deal of interest has developed towards the isolation of bioactive compounds from marine sources due to their numerous health benefits. Furthermore, marine algae are valuable sources ...
Ionophoric and aptameric recognition-modulated electroactive polyaniline films for the determination of tetrodotoxin
(University of the Western Cape, 2014)
Tetrodotoxin (TTX) is a nonpeptidic neurotoxin with a high rate of food poisoning mortality (60%) that has been associated with the consumption of diets from puffer fish and mud snails harbouring TTX-producing bacteria. ...
Quantum dots genosensor for Her2/Neu oncogene - a breast cancer biomarker
(University of the Western Cape, 2014)
The human epidermal growth factor receptor (HER)-family of receptor tyrosine kinases; human epidermal growth factor receptor 1, human epidermal growth factor receptor 2, human epidermal growth factor receptor 3 and human ...
Novel 3-mercaptopropionic acid capped iridium selenide quantum dots modified electrochemical immunosensor for the detection of fish toxin, nodularin
(University of the Western Cape, 2012)
A novel 3-mercaptopropionic acid capped iridium selenide quantum dots based label free impedimetric immunosensor was successfully constructed. The 3-mercaptopropionic acid capped iridium selenide quantum dots synthesized ...
