  • Kruger, Anneke (Stellenbosch : Stellenbosch University, 2007-03)
    ENGLISH ABSTRACT: This study comprises the synthesis and characterisation of N-heterocyclic carbene complexes of group 10 metals with the main focus on such complexes with the nucleophilic N-atom in a position further ...
  • Bailly, Nathalie (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: The primary aim of this study was to investigate the feasibility of the amphiphilic block copolymer poly((vinylpyrrolidone)-b-poly(vinyl acetate)) (PVP-b-PVAc) as a vehicle for hydrophobic anti-cancer ...
  • Ganeva, Desislava Evgenieva (Stellenbosch : Stellenbosch University, 2003-12)
    ENGLISH ABSTRACT: The general objective of this research was to develop a new approach to direct templating, where the organised phases of polyelectrolyte-surfactant complexes are used as hosts for organic polymerisation ...
  • Al-Aeeb, Ahmed Z. (Stellenbosch : Stellenbosch University, 2013-03)
    ENGLISH ABSTRACT: A new class of nanocolorants is described for the use as a colorant in hot-melt ink application for ink-jet printing technology. An inverse miniemulsion polymerization process was utilized successfully ...
  • Bushula, Vuyiswa Sylvia (Stellenbosch : Stellenbosch University, 2008-12)
    The genus Fusarium contains members that are phytopathogens of a number of agricultural commodities causing severe diseases such as wilts and rots. Fusarium species also secrete mycotoxins that have devastating effects ...
  • Buthelezi, E. Z.(Edith Zinhle) (Stellenbosch : University of Stellenbosch, 2004-04)
    ENGLISH ABSTRACT: This study forms part of a larger investigation which has as a primary objective the development of a comprehensive theoretical description of all the processes which contribute to the continuum in ...
  • Greyling, Guillaume Hermanus (Stellenbosch : Stellenbosch University, 2011-03)
    ENGLISH ABSTRACT: The primary objective of the work was to investigate the negative thermal expansion of organic materials and to determine the mechanisms governing this phenomenon by using the principles of crystal ...
  • Razafindrakoto, Ando Desire (Stellenbosch : Stellenbosch University, 2013-03)
    ENGLISH ABSTRACT: While the notions of open and closed subsets in a topological space are dual to each other, they take on another meaning when points and complements are no longer available. Closure operators have ...
  • Burger, B. V.   Viviers, Marlize Z.   Le Roux, Niel J.   Morris, John   Bekker, Jan P. I.   Le Roux, Maritha (Springer New York, 2013)
    The strong bond formed between ewe and lamb shortly after parturition is an important factor in lamb survival. Evidence exists that the ewe can distinguish her lamb by its unique smell, but the constituents of such a ...
  • Baruani, Atumbe Jules (Stellenbosch : Stellenbosch University, 2007-12)
    ENGLISH ABSTRACT: We use Evolutionary Multi-Objective Optimisation (EMOO) algorithms to optimise objective functions that reflect situations in communication networks. These include functions that optimise Network ...
  • De Jongh, Albert (Stellenbosch : Stellenbosch University, 2004-04)
    ENGLISH ABSTRACT: It is possible to improve on the accuracy of a single neural network by using an ensemble of diverse and accurate networks. This thesis explores diversity in ensembles and looks at the underlying theory ...
  • Heydenrych, Greta (Stellenbosch : Stellenbosch University, 2001-03)
    ENGLISH ABSTRACT: Please refer to fulltext for abstract
  • Bytebier, Benny   Sakwa, Jane   Kurzweil, Hubert (BioOne, 2004-01)
    The orchid taxa Brachycorythis ovata subsp. schweinfurthii, Habenaria arianae and Habenaria disparilis are newly recorded for Tanzania, while Brachycorythis congoensis is newly recorded for the floral region T7. A stable, ...
  • Etmimi, Hussein Mohamed (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: New methods are described for the synthesis of polymer/graphite nanocomposites using the miniemulsion polymerization process. Natural graphite was functionalized by oxidation to produce graphite oxide ...
  • Coetzee, Jacorien (Stellenbosch : University of Stellenbosch, 2007-03)
    A comprehensive, comparative structural study of gold(I), gold(II) and gold(III) compounds with the general formula [Aux(C6F5)y(tht)z] (tht = tetrahydrothiophene) was performed. The series of compounds included the ...

  • Strasser, Christoph Erik (Stellenbosch : Stellenbosch University, 2008-12)
    Novel gold(I) trithiophosphite complexes were synthesised by utilising the ligands P(SR)3 (R = Me, Ph) and 1,2-bis(1,3,2-dithiaphospholan-2-ylthio)ethane (2L). Reaction with (tht)AuCl or (tht)AuC6F5 readily yielded the ...
  • De Vries, Andrew Robert (Stellenbosch : University of Stellenbosch, 2006-12)
    The synthesis and characterization of a new tertiary alcohol (2-octyl-2-dodecanol) and “bushy-tailed”, hydrophobic acrylic monomer (2-octyl-dodecyl acrylate) from a 1-decene dimer (2-octyl-1-dodecene) precursor that was ...
