A fluorescence spectroscopic study of a coagulating protein extracted from Moringa oleifera seeds
Kwaambwa, H.M.; Maikorera, R. (Elsevier B.V. www.elsevier.com/locate/colsurfb, 2007)The fluorescence studies of coagulating protein extracted from Moringa oleifera seeds have been studied using steady-state intrinsic fluorescence. The fluorescence spectra are dominated by tryptophan emission and the ... -
The phase separation behaviour and the viscoelastic properties of particles with non-adsorbing polymers: Part I - Experimental study
Goodwin, J.W.; Hughes, R.W.; Kwaambwa, H.M.; Reynolds, P.A. (Elseview Science B.V. www.elsevier.nl/locate/colsurfa, 2000)A series of well characterised cis-polyisoprene polymers have been added to dispersions of PHS coated PMMA particles in dodecane. At a molecular weight of 8000 g mol−1 and above, these systems showed phase separation at ... -
A study of the removal of heavy metals from aqueous solutions by Moringa oleifera seeds and amine-based ligand 1,4-bis[N,N-bis(2-picoyl)amino]butane
Obuseng, V.; Nareetsile, F.; Kwaambwa, H.M. (Elsevier Science Ltd, www.elsevier.com/locate/aca, 2012)Uptake for lead, copper, cadmium, nickel and manganese from aqueous solution using the Moringa oleifera seeds biomass (MOSB) and amine-based ligand (ABL) was investigated. Experiments on two synthetic multi-solute systems ... -
Viscosity behaviour of particles with non-adsorbing polymers Part III—experimental study
Goodwin, J.W.; Hughes, R.W.; Reynolds, P.A.; Kwaambwa, H.M. (Elsevier B.V. www.elsevier.com/locate/colsurfa, 2004)A series of well characterised cis-poly(isoprene) (PIP) polymers (Mw = 1180, 8000, 28 300, 31 500, 86 000, 115 000 and 130 000) have been added to dispersions of poly(12-hydroxystearic acid) (PHS) coated poly(methylmethacrylate) ... -
Viscosity, molecular weight and concentration relationships at 298K of low molecular weight cis-polyisoprene in a good solvent
Kwaambwa, H.M.; Goodwin, J.W.; Hughes, R.W.; Reynolds, P.A. (Elsevier B.V. www.elsevier.com/locate/colsurfa, 2007)Aseries of six well characterised homopolymers of cis-polyisoprene (PIP) ranging from 1180 to 115,000 molecular weight were utilised to explore viscosity and the scaling relationship between viscosity and concentration ...
