Thiolato schiff base complexes of nickel and palladium as mesogens and molecular wires
(University of the Western Cape, 2003)
Thermal analysis data of compounds A, C, F and I established that they were nonmesogenic
while E and G were found to be mesogenic. The lack of mesogenic behaviour
of A could be attributed to hydrogen bonding. The ...
Palladium surface-modified rare earth metal-based ab5 type hydride-forming materials
(University of the Western Cape, 2008)
Driven by mounting standards of living and a growing population, South African energy consumption is expected to increase dramatically within the next decade. The increased demand for more energy will require enormous ...
Pyrazolyl palladium complexes with heterocyclic carbonyl linkers as catalyst precursors for ethylene and phenylacetylene polymerization.
(University of the Western Cape, 2003)
The pyrazolyl ligands 2,6-bis(3,5-r2p*azolylcarbonyl)pyridine {r : 'bu (l1), me (l2)),2,6-bis(3-methylpyrazolylcarbonyl)pyridine(l3)'2'6- bis(pyrazolylcarbonyl)pyridine (l4) and 2,5-bis(3,5-rzpyrazolylcarbonyl)thiophene { ...
Titanium compounds and plant growth
(University of the Western Cape, 2001)
The effect of titanium compounds on the growth of tomato plants, Lycopersicum
esculentum (cultivar Floridade), was studied under greenhouse conditions.
Aqueous suspensions (TiO2) and solutions (complexes of titanium (IV) ...
The oxidation of the lower primary alcohols ln a catalytic membrane reactor
(University of the Western Cape, 2000)
Methanol and ethanol are important chemical feedstock used in industrial chemistry, since they are the starting materials for the synthesis of various products, including hydrocarbons and mild oxidation products. For ...
ISOLATION AND CHARACTERIZATION OF ANTIMICROBIAL COMPOUNDS FROM GALENIA AFRICANA
(University of the Western Cape, 2001)
Galenia africona, commonly known as "kraalbos" or "geelbos" belonging to the family Aizoaceae, is a dominant plant throughout the Namaqualand area. It is an active invader and is especially abundant in disturbed areas ...
Chemical compositions and leaching behaviour of some South African fly ashe
(University of the Western Cape, 2008)
Fly ash is the most abundant of the waste materials generated from coal combustion in coal-fired power stations. South Africa uses more than 100 million tonnes of low grade bituminous coal annually to produce cheap electricity ...
Characterization and Chemical Speciation Modelling of Saline Effluents at Sasol Synthetic Fuels Complex-Secunda and Tutuka Power Station
(University of the Western Cape, 2009)
Chemical speciation and the evaluation of species distribution is the key to understanding the potential of brines to form scale or corrode the water circuit as well as the potential of mobility and release trends of the ...
Spectroelectrochemical determination of the antioxidant properties of carpobrotus mellei and carpobrotus quadrifidus natural products
(University of the Western Cape, 2009)
South African Carpobrotus species have been found to contain hydrolysable tannins, various tlavonoids e.g. rutin and hyperoside, phytosterols and aromatic acids which have a diverse range of pharmacological properties ...
Removal of sulphates from South African mine water using coal fly ash
(University of the Western Cape, 2009)
South African power stations generate large amounts of highly alkaline fly ash (FA). This waste product has a serious impact on the environment. Acid mine drainage (AMD) is another environmental problem associated with ...
