In this thesis the main capillary electrodriven chromatographic techniques (i.e. Capillary Electrochromatography CEC, Micellar Electrokinetic Chromatography MEKC and Microemulsion Electrokinetic Chromatography MEEKC) ...
The supramolecular chemistry of novel synthetic biomacromolecular assemblies
(Stellenbosch : Stellenbosch University, 2004-04)
ENGLISH ABSTRACT: Over the past decade peptide bola-amphiphiles have been the subject of much attention because of their role as potential models of functionalised membranes and as new generation surfactants. In the quest ...
The development of analytical techniques for studying degradation in impact polypropylene copolymers
(Stellenbosch : University of Stellenbosch, 2009-03)
Unstabilised polyolefins are susceptible to degradation when exposed to molecular oxygen, heat, irradiation as well as chemical and mechanical stimuli. Oxidation leads to changes in molecular properties such as molecular ...
