A speciation study of various Pt(II) and Pt(IV) complexes including hexaaquaplatinum(IV) by means of 195Pt NMR spectroscopy, in support of a preliminary study of the oxidation mechanism of various Pt(II) complexes
(Stellenbosch : Stellenbosch University, 2012-12)

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 ...
Understanding the origin of 35/37Cl and 16/18O isotope effects on 195Pt and 103Rh NMR nuclear shielding in selected Pt(IV) and Rh(III) complexes : a DFT study
(Stellenbosch : Stellenbosch University, 2013-12)
Please refer to full text to view abstract.
What is the possible origin of the 195Pt NMR shielding in the solid state? X-ray diffraction, solid-state NMR studies of deceptively simple C2[PtX6] salts (C = various cations, X = Cl- and Br-)
(Stellenbosch : Stellenbosch University, 2015-03)
ENGLISH ABSTRACT: The primary objective of the work presented in this thesis is to investigate the sensitivity and nature
of the 195Pt chemical shift in the solid-state, as a function of temperature. We have carried out ...

Analysis of vegetable oils, seeds and beans by TGA and NMR spectroscopy
(Stellenbosch : University of Stellenbosch, 2011-03)
ENGLISH ABSTRACT: Due to the commercial, nutritional and health value of vegetable oils, seeds and beans, the
analysis of their components is of much interest. In this dissertation oil-containing food
products, specifically ...
Chemical speciation of RhIII complexes in acidic, halide-rich media by means of 103Rh NMR spectroscopy : the importance of speciation in the selective separation and recovery of rhodium
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: In this thesis, the recovery of RhIII from both synthetically prepared and authentic
industrial PGM-containing solutions was systematically investigated via organic precipitation
methods using several ...
