Microheterogeneous solid polymer electrolyte (SPE) membranes for electrocatalysis
(Stellenbosch : Stellenbosch University, 2002-04)
ENGLISH ABSTRACT: The deposition of platinum catalyst on cation-exchange membranes was achieved by
a counter diffusion deposition method known as the Takenaka- Torikai method. The
morphology of the platinum catalyst on ...
Supported zeolite A membranes. Feasibility of the static transverse synthesis : a new approach
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: As there is inadequate control of the hydrothermal synthesis technique used to date in the
synthesis of zeolite A membranes, the feasibility of a new synthesis approach was investigated,
namely the ...
Propylene / 1-pentene random copolymers : preparation, characterisation and commercialisation
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: Most polypropylene copolymers commercially available have ethylene, and to a
lesser degree t-butene as comonomers. Commercially available higher a-olefins,
mostly even-numbered, are seldom used for the ...
Synthesis, characterization and testing of nano-structured particles for effective impact modification of glassy amorphous polymers
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: The synthesis of structured nanoparticles, in particular core/shells, IS of great
technological and economical importance to modem materials science. One of the
advantages of structured particles is ...
Structure/property relationship of model alkali-soluble rheology modifiers synthesised via the RAFT process
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: Alkali-soluble rheology modifiers are commercially synthesised via conventional freeradical
polymerisation processes. This results in the end product having certain
limitations; there is poor control ...
Fischer-Tropsch ionomeric waxes
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: This dissertation describes work done on Fischer- Tropsch ionomeric waxes. The
waxes are characterized with respect to the method of manufacture, the mechanism of
the oxidation process, the saponification, ...
Reversible addition-fragmentation transfer polymerization in heterogeneous aqueous media
(Stellenbosch : Stellenbosch University, 2004-04)
ENGLISH ABSTRACT: The study presented in this dissertation had as primary aim to develop pathways to
heterogeneous aqueous polymerizations that had living characteristics. To this end,
the reversible addition fragmentation ...
Real-time investigation of fouling phenomena in membrane filtrations by a non-invasive ultrasonic technique
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: Membrane fouling is universally accepted as one of the most critical problems
limiting the wider application of membranes in liquid separations. The development
and utilization of a suitable non-invasive ...
Groundwater chemistry and supplementary sources of freshwater in Arid environments : groundwater salinisation, solar desalination & fog collection
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: Freshwater is the most fundamental of all life-supporting resources that determine our
social, economic and political wellbeing. It is, however, only a small percentage of
the world's water resources ...
