Drying of PAAm hydrogels at various temperatures: A fluorescence study
Aktaş, Demet Kaya; Evingür, Gülşen Akın; Pekcan, Mehmet Önder (Taylor & Francis Group, 2007-05)The steady-state fluorescence (SSF) technique was employed for studying the drying of polyacrylamide (PAAm) hydrogels. Disc-shaped hydrogels were prepared by free-radical crosslinking copolymerization of acrylamide (AAm) ... -
In situ fluorescence study of swelling, sorption and desorption processes in and out of PAAm gels
Evingür, Gülşen Akın; Karslı, Kadir; Pekcan, Mehmet Önder (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 ... -

Study on swelling of hydrogels (PAAm) at various temperatures by using fluorescence technique
Kaya Aktaş, Demet; Evingür, Gülşen Akın; Pekcan, Mehmet Önder (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'- ... -
Studying on the small molecule diffusion into hydrogels: a fluorescence study
Evingür, Gülşen Akın; Karslı, Kadir; Pekcan, Mehmet Önder (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 ... -
