The preparation and characterization of multinuclear catalysts based on novel dendrimers : application in the oligomerization and polymerization of unsaturated hydrocarbons
(Stellenbosch : University of Stellenbosch, 2011-03)
In this thesis we describe the application of novel salicylaldimine and iminopyridyl
nickel metallodendrimer complexes as catalysts in the transformation of á-olefins as well as
in the polymerization of norbornene.
New ...
Controlled polymerization of amino acid derivatives
(Stellenbosch : University of Stellenbosch, 2008-03)
This dissertation can be broken into two parts comprising different strategies to synthesise novel poly-amino acid based polymers.
The use of recently developed nickel(0) and cobalt(0) metal catalysts for the living ...
New ligands for gold : bonding mode and structural complex characterisation
(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 ...
Interactions of quinoline antimalarial drugs with ferrihaem : structural and kinetic insights into the inhibition of malaria pigment formation
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: The work in this dissertation provides structural and kinetic insight into the mechanism of
action of quinoline antimalarial drugs which may aid rational drug design. Quinoline
antimalarial drug-ferrihaem ...
Synthesis and characterization of multiphase copolymers
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: Multiphase copolymers generally consist of copolymers where the disparate natures of each
of the segments results in complex phase-segregated morphologies in the solid state. The
outstanding properties ...
Comprehensive multidimensional gas chromatography for the analysis of Fischer-Tropsch products
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: The analysis of Fischer–Tropsch–derived (FT–derived) synthetic crude and derived products
is very challenging because of the highly complex nature of these products. In this study, the
use of comprehensive ...
Novel transition metal complexes based on N,N and N,P ligands as catalysts for ethylene transformation reactions
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: see full text for abstract.
Electrospinning of polyacrylonitrile nanofibres with additives : study of orientation and crystallinity
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT:
Polyacrylonitrile, (PAN), polymers are of interest due to their many unique characteristics in comparison
to most other fibre forming polymers. The focus of this study was the effect of electrospinning ...
Photoelectrochemical detection of inorganic mercury in aqueous solutions
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Due to the adverse human health effects associated with mercury (Hg) toxicity, an
innovative method for inorganic mercury (Hg2+) determination in aqueous solutions
was investigated. The method of Hg2+ ...
Development of novel supramolecular framework materials based on organic salts
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: The aim of the work presented in this thesis was to design ionic organic framework materials based on carboxylate salts with the intention of engineering interesting properties, such as porosity, into ...
