Development of crosslinkable, thermoplastic polyurethanes for cardiovascular prostheses
(Stellenbosch : University of Stellenbosch, 2006-12)
Existing thermoplastic polyurethanes (TPUs), used in the manufacturing of
cardiovascular devices, still have unproven long-term biostability and may be prone to
excessive plastic deformation when subjected to cyclic ...
Production of hollow fibers by co-electrospinning of cellulose acetate
(Stellenbosch : University of Stellenbosch, 2009-03)
The study concerns the use of the electrospinning technique for the formation of
cellulose acetate hollow nanofibers. These hollow fibers are used to manufacture
hollow fiber membranes. Important properties that should ...
Investigation of electrochemical combustion plant for rural water disinfection and industrial organic effluent removal
(Stellenbosch : University of Stellenbosch, 2004-04)
ENGLISH ABSTRACT: Recent years have seen the development of various treatment methods for the purification
of industrial waste waters due to the increased demand for reduced pollutant
effluents. Aqueous waste streams ...
Modified polysaccharide-based particles for strengthening paper
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: The ongoing trend in papermaking industries is to lower production costs by increasing
the low cost filler content in the sheets. However, the disruption of inter-fibre bonding is
accompanied by a ...
Poly(vinyl alcohol) / polyamide thin-film composite membranes.
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: The aim of this study was to modify the surface of polyethersulfone (PES) ultrafiltration (UF)
membranes to produce a more hydrophilic membrane by cross-linking poly(vinyl alcohol) (PVA) with
sodium ...
