Hydrogen selective properties of cesium-hydrogensulphate membranes
(University of the Western Cape, 2006)
The production procedure of a CsHS04-Si02 composite membrane was optimized in order to obtain the highest possible H2:C02 and H2:C~ Idea selectivity permeance. The optimized membrane preparation procedure led to the ...
Oxidative fixation of dinitrogen by photocatalysis
(University of Western Cape, 2000)
The heterogeneous photocatalytic oxidation of dinitrogen to nitrate, NO3 and/or nitrite, no2 using peroxy species of titanium (IV) in aqueous suspensions has been investigated. The photocatalysts used were titanium peroxide ...
The synthesis of the cyclometallated palladium complexes and their applications in olefin oligomerization and in phenylacetylene oligomerization/polymerization
(2007)
This thesis reports the synthesis of the imine ligands from Schiff base condensation reaction of aldehyde derivatives and equimolar quantities of aniline derivatives. The imine ligands spectrometry.
Hydrothermal synthesis and optimisation of zeolite Na-P1 from South African coal fly ash
(2009)
Millions of tonnes of fly ash are generated worldwide every year to satisfy the large demand for energy. Management of this fly ash has been a concern and various approaches for its beneficial use have been investigated. ...
Geological modeling of the offshore Orange Basin, west coast of South Africa
(UWC, 2009)
Separation between the South American and African plate’s occurred along the present day Atlantic margin during the Middle to Late Jurassic leading to
the formation of a passive margin along the west coast of Southern ...
Pyridine carboxamide and pyrazole palladium(II) complexes as catalyst precursors for phenylacetylene polymerization
(University of the Western Cape, 2005)
The objectives of this project were to synthesize and characterise pyridine carboxamide ligands and their palladium complexes and investigate their catalytic activity in the polymerization process of phenylactylene.
Homogeneity of nanophase electrocatalysts supported on mesoporous materials
(University of the Western Cape, 2006)
Synthesis and characterisation of proton conducting membranes for direct methanol fuel cell (DMFC) applications
(University of the Western Cape, 2005)
For a direct methanol fuel cell (DMFC), the proton exchange membrane must conduct protons and be a good methanol barrier. In addition to the high methanol permeability achieved by these membranes, they are very expensive ...
Metal complexes based on monomeric and dendrimeric pyrrole-imine ligands as catalytic precursors
(University of the Western Cape, 2007)
Over the recent past, organometallic chemistry has grown and the impact of catalytic applications in various chemical technologies has rapidly evolved from the realm of academic laboratories into full-scale industrial ...
Phytochemical studies of Helichrysum patulum
(University of the Western Cape, 2006)
Since Helichrysum is known by the indigenous people of Africa for therapeutic properties, such as against colds, flu and wounds, the aim of this study was to focus on the patulum species found predominantly in the Western ...
