Temperature effect on drying and swelling of kappa carrageenan gels: A steady state fluorescence study
(Wiley-V C H Verlag GMBH, 2008)
A novel technique based on in situ steady state fluorescence (SSF) measurements is introduced for studying drying and swelling Of kappa(-) carrageenan (kappa carrageenan) gels at various temperatures. kappa(-) carrageenan ...
In situ fluorescence study of swelling, sorption and desorption processes in and out of PAAm gels
(Wiley-V C H Verlag GMBH, 2008-05)
Small molecule sorption and desorption in and out of polyacrylamide (PAAm) gels were studied at various temperatures. Pyranine (P(y)) dissolved in water used as a probe. Fluorescence emission intensity, I(p) from P(y) was ...
Dissolution of Al2O3-polystyrene latex composites: A fluorescence study
(Taylor & Francis Ltd, 2005)
This work reports the use of the steady state fluorescence (SSF) technique to study dissolution of a composite film formed from a mixture of Al 2O3 and polystyrene (PS) latex particles. The composite films were cast from ...
Universal behaviour of gel formation from acrylamide-carrageenan mixture around the gel point: A fluorescence study
(Taylor & Francis Group, 2006-08)
The steady state fluorescence (SSF) technique was used to study the sol-gel transition, for the solution free radical crosslinking copolymerization of acrylamide (AAm) with various carrageenan content. N, N'- methylenebis ...
Small molecule sorption and desorption in and out of iota-carrageenan gels
(Taylor & Francis Group, 2007-08)
Small molecule sorption and desorption in and out of Iota-Carrageenan was studied by using steady-state fluorescence (SSF) technique. Pyranine dissolved in water used as fluorescence probe. Fluorescence emission intensity, ...
Small molecule desorption prior to dissolution of a polymeric glass
(Wiley Subscription Services, Inc., A Wiley Company, 2006-07-15)
Poly(methyl methacrylate) (PMMA) discs in various molecular weights (M-w) were prepared by free-radical polymerization. Pyrene (Py) was introduced during polymerization as a fluorescence probe. In situ steady state ...
Films formed from polystyrene latex/clay composites: A fluorescence study
(Springer New York, 2005-07)
This study reports a steady-state fluorescence (SSF) technique for studying film formation from surractant-free polystyrene (PS) latex and Na-montmorillonite (SNaM) composites. The composite films were prepared from pyrene ...
Study on swelling of hydrogels (PAAm) at various temperatures by using fluorescence technique
(Springer US, 2007-10)
Steady-state fluorescence (SSF) technique was employed for studying swelling of polyacrylamide (PAAm) hydrogels. Disc-shaped gels were prepared by free-radical crosslinking copolymerization of acrylamide (AAm) with N, N'- ...
Poly (styrene) latex/modified na-activated bentonite nanocomposite films: a fluorescence study
(Elsevier Science BV, 2008-12)
We studied film formation of composites of surfactant-free polystyrene (PS) nanoparticles and modified Na-activated bentonite (MLB), by steady state fluorescence (SSF) technique. The films were prepared from a mixture of ...
Small molecule desorption from a swelling polymeric glass in polymer solution: Energy transfer method
(Elsevier Science Sa, 2005-07-15)
Direct energy transfer (DET) method conjunction with fast transient fluorescence (FTRF) technique were used to study small molecule desorption from a swelling poly(methyl methacrylate) (PMMA) glass in polymer solution, ...
