Syntheses, electrochemistry and spectroscopic studies of metallocene-containing porphyrin complexes with biomedical applications
(University of the Free State, 2010-05)
In this study, a series of carboxylic acid functionalised pyrrole derivatives and ferrocene- and ruthenocene-containing dipyrromethanes were synthesised. Porphyrin complexes bearing a mono-carboxylic acid functional group ...
Comparison of injection moulded, natural fibre reinforced composites with PP and PLA as matrices
(University of the Free State (Qwaqwa Campus), 2010-12-07)
Poly(lactic acid) (PLA) and polypropylene (PP) were comparatively investigated as matrices for injection moulded composites containing small (1-3 wt.%) amounts of short sisal fibre. The polymers and fibres were mechanically ...
