Phase Transitions in Pure and Hybrid Hydrogels: A Fluorescence Study
(Wiley, 2009)
Recent observations on phase transitions around the critical point showed that the critical exponents differed drastically from percolation results and classical results for pure hydrogel systems depending on monomer ...
Critical Exponents of Thermal Phase Transitions of kappa-Carrageenan in Various Salt Solutions
(Wiley-VCH Verlag GmbH, 2009)
The steady state fluorescence (SSF) technique was employed to study the phase transitions Of kappa-carrageenan in NaCl and KCl solutions. Pyranine was used as a fluorescence probe for monitoring these transitions. Scattered ...
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 ...
