The cyclotron production of selected radionuclides using medium energy protons
(Stellenbosch : Stellenbosch University, 2008-03)
ENGLISH ABSTRACT: Radiochemical research involving ion exchange chromatography is of paramount
importance to the future of radionuclide production at the Radionuclide Production
Group (RPG) of iThemba LABS. It is required ...
A multinuclear magnetic resonance spectroscopy study of E/Z configurational isomers of unsymmetrical N-alkyl-N-alkyl(aryl)-N'-acylthioureas of platinum(II) complexes
(Stellenbosch : Stellenbosch University, 2006-12)
ENGLISH ABSTRACT: The partial double bond character of the carbon-nitrogen bond of the (S)C-NRR’ moiety results in unsymmetrical
dialkyl-substituted N-alkyl-N-alkyl(aryl)-N’-acylthioureas, R”C(O)NHC(S)NRR’ (HL) displaying ...
Use of the RAFT technique as an efficient method to synthesise well defined polymer-clay nanocomposites with improved properties
(Stellenbosch : University of Stellenbosch, 2009-03)
Synthesis and structural characterization of two novel cationic and three new neutral
reversible addition–fragmentation chain transfer (RAFT) agents is described. The
cationic RAFT agents bear a quaternary ammonium group: ...

(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: Please refer to full text for abstract
Environmental electrochemistry of organic compounds at metal oxide electrodes
(Stellenbosch : Stellenbosch University, 2004-12)
ENGLISH ABSTRACT: This study investigates the electrochemical oxidation of phenol. Phenol is a major toxin
and water pollutant. In addition, during water treatment it reacts with chlorine to produce
carcinogenic ...
Application of modern analytical techniques and chemometric methods to the chemical characterisation of South African wines : determination of non-volatiles
(Stellenbosch : Stellenbosch University, 2004-12)
ENGLISH ABSTRACT: The present study deals in the first instance with the improvement of current analytical
techniques for the analysis of the non-volatile content of wines. An improved sample
preparation method, using ...

(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: The sungazer, Cordylus giganteus, is an endangered lizard species belonging to the
family Cordylidae. It has been speculated that the function of semiochemical
communication is performed by two types ...
Separation of 103Pd from Ag and Rh targets for production of '103 Pd seeds' for prostate cancer brachytherapy
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: Radiochemical separation of 103Pd from natAg, usmg a 66 MeV proton-induced
reaction at iThemba LABS, was studied and a radiochemical method was developed
for the separation. For the separation, which ...
Structure elucidation of and synthetic approaches to monatin, a metabolite from Schlerochiton ilicifolius
(Stellenbosch : Stellenbosch University, 1990-12)
ENGLISH ABSTRACT: Monatin, or 4-hydroxy-4-(3-indolylmethyl) glutamic acid is a high-intensity sweet tasting
amino acid found in the root bark of the indigenous plant Schlerochiton ilicifolius. In the
thesis the isolation, ...
Electrochemical purification of hazardous organic compounds from wastewater by means of novel electrode materials and a solid-polymer-electrolyte-reactor system
(Stellenbosch : Stellenbosch University, 1999-12)
ENGLISH ABSTRACT: A novel sol-gel Ti/Sn02/Sb205 electrode material for the electro catalytic oxidation
(combustion) of hazardous organic compounds in water has been designed and characterised.
Kinetic studies revealed ...
