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'- ...
Film formation from TiO2-polystyrene latex composite: a fluorescence study
(Taylor & Francis Group, 2007-03-01)
This work reports the use of the steady state fluorescence (SSF) technique for studying film formation from TiO2 covered polystyrene (PS) latex particles. The composite films were prepared from pyrene (P)-labeled PS particles ...
Swelling activation energy of kappa-carrageenan in its gel state: A fluorescence study
(John Wiley & Sons Inc, 2007-12-15)
A steady-state fluorescence technique was employed to study the swelling Of K-carrageenan gels at various temperatures. Pyranine was used as a fluorescence probe. The fluorescence intensity of pyranine was measured during ...
Studying on the small molecule diffusion into hydrogels: a fluorescence study
(Amer Inst Physics, 2007)
In situ steady state fluorescence experiments (SSF) were reported during the diffusion of water molecules into PAAm in gels at various temperatures. The fluorescence emission intensities, Ip increased continuously as water ...
