Thesis (MSc)--Stellenbosch University, 2004.<br>ENGLISH ABSTRACT: Capillary electrophoresis (CE) has recently attracted considerable attention as a promising analytical technique for the separation of cations and anions in complex matrices. Determination of ions in aqueous samples using capillary electrophoresis can be accomplished with indirect UV detection. Most inorganic ions have weak absorption profiles in the UV-Vis wavelength range. These mostly non-absorbing species are commonly detected by indirect UV absorbance through addition of an absorbing co-ion (chromophore) into the ele

Abstract:

The problem with which this research is concerned is the determination of inorganic anions and cations with single injection ion chromatography. Direct detection of the separated analyte ions occurs after the analyte ions have passed through ion-exchange resins where they are separated according to their affinity for the ion-exchange resin active sites. The techniques involve the use of essentially a non-suppressed ion chromatographic system followed by a suppressed ion chromatographic system. With this system it is possible to accomplish both qualitative and quantitative determinations.

To be specific, we consider an asymmetrically charged lipid bilayer, in which only one layer is negatively charged. In particular, we study how dielectric discontinuities and charge correlations among lipid charges and condensed counterions influence the effective cha

Abstract:

The significant involvement of metal ions and complexes in biological processes and systems has, over recent times, led to the realization that considerable scope exists for the design of metal-based therapeutics. While considerable work in this area has been in the field of coordination complexes, the large diversity of structure and unique bonding modes of organometallic complexes also suggests that these systems may find use as therapeutic agents. This thesis seeks to explore this hypothesis through the in vitro / in vivo anticancer evaluation of a family of cationic organoruthenium Cp* are

Abstract:

L'objectif de cette étude est de synthétiser de nouveaux polymères aux propriétés spécifiques, en utilisant pour la première fois comme monomère un aldocétène : l'éthylcétène. La synthèse de l'éthylcétène a été entreprise en utilisant deux procédés distincts :d'une part la méthode de McCarney, qui a permis de le préparer dans un solvant par entraînement à la vapeur, et d'autre part le craquage de l'anhydride butyrique à 575°C sous 40mbar.La polymérisation ionique de l'éthylcétène a ensuite été réalisée, dans différentes conditions de solvant, de température et avec plusieurs amorceurs. La poly

Resultados de diferentes técnicas experimentais têm sugerido que esses peptídeos permeabilizam as membranas pela formação de poros. Parte dos peptídeos caracterizados apresentam especificidade de disrupção para membranas de bactérias, em detrimento das membranas dos hospedeiros. Essa carac

Abstract:

This study focuses on the development of novel two-stage esterification-transesterification synthesis of biodiesel from used cooking oil (UCO) using novel heterogeneous catalysts. The esterification of the UCO was investigated using three types of ion exchange resins catalysts including Purolite D5081, Purolite D5082 and Amberlyst 15. Of all the catalysts investigated, Purolite D5081 resin showed the best catalytic performance and was selected for further optimisation studies. From the optimisation study, it was found that the external and internal mass transfer resistance has negligible effec
