Modelling of Swelling by the Fluorescence Technique in Kappa Carrageenan Gels
(Amer Inst Physics, 2011)
Kappa (-kappa) carrageenan gels prepared with various carrageenan concentrations in pure water were completely dried and then swelled in water vapor. Steady state fluorescence measurements were performed using a spectrometer ...
Oxygen Diffusion into Polymer-Clay Composite Films as a Function of Clay Content and Temperature
(Wiley-VCH Verlag GmbH, 2009)
A simple fluorescence technique is proposed for the measurement of the diffusion coefficient of oxygen into polystyrene-clay composite films as a function of clay content and temperature. The composite films were prepared ...
Gelation electrical conductivity and elasticity of PAM- MWNT
(Cambridge Univ Press, 2011)
Polyacrylamide- Multiwalled carbonnanotube (PAM- MWNT) composites were prepared via free radical crosslinking copolymerization with different amounts of MWNT varying in the range between 0.1 and 15 wt. %. PAM- MWNT composite ...
