ENGLISH ABSTRACT:
Living chains prepared by RAFT polymerization and NMP reactions using Z-carboxylate and Z-phosphate RAFT agents, and X-phosphate NMP initiators, were efficiently attached to the surface of magnetic ...
Electrospinning of polyacrylonitrile nanofibres with additives : study of orientation and crystallinity
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT:
Polyacrylonitrile, (PAN), polymers are of interest due to their many unique characteristics in comparison
to most other fibre forming polymers. The focus of this study was the effect of electrospinning ...
Photoelectrochemical detection of inorganic mercury in aqueous solutions
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Due to the adverse human health effects associated with mercury (Hg) toxicity, an
innovative method for inorganic mercury (Hg2+) determination in aqueous solutions
was investigated. The method of Hg2+ ...
