Mechanical properties of graphene oxide-polyacrylamide composites before and after swelling in water 

Evingür, Gülşen Akin; Pekcan, Önder (Springer, 2018)
Polyacrylamide (PAAm) hydrogels have been proposed for use as promising biomaterials in biomedical and tissue engineering but their poor mechanical and water-retention properties have hindered their development. Graphene ...

Effect of LCST on the swelling of PAAm-NIPA copolymers: a fluorescence study 

Evingür, Gülşen Akin; Pekcan, Önder (Springer, 2012)
Temperature sensitive copolymers were prepared by free radical crosslinking copolymerization in aqueous solution with different molar percentage of N-isopropylacrylamide (NIPA) and acrylamide (AAm) monomers. NN'-methylenebis ...

Effect of temperature and graphene oxide on the swelling of PAAm-GO composite gels 

Osma, Büşra; Akın Evingür, Gülşen; Pekcan, Önder (Avestia Publishing, 2019)
Graphene oxide (GO) is a two dimensional carbon material with similar one-atom thickness, and is a light material having extremely high strength and thermal stability [1]. Thus, GO is an efficient filler for the enhancement ...

Elastic Properties of a Swollen PAAm-NIPA Copolymer with Various NIPA Contents 

Evingür, Gülşen Akin; Pekcan, Önder (Taylor & Francis, 2014)
Copolymer based on cross-linked polyacrylamide (PAAm) having N-isopropylacrylamide (NIPA) was prepared and their elastic properties were studied as a function of NIPA contents. NIPA content dependency of the shear modulus ...

Kinetic models for the dynamical behavior of polyacrylamide (PAAm)-kappa-carrageenan (kappa C) composite gels 

Evingür, Gülşen Akın; Pekcan, Önder (Springer, 2015)
A fluorescence method was employed for studying the drying and swelling of PAAm-kappa C composite gels which were formed from acrylamide (AAm) and N N'- methylenebisacrylamide (BIS) with various kappa-carrageenan (kappa ...

Effect of multiwalled carbon nanotube (MWNT) on the behavior of swelling of polyacrylamide-MWNT composites 

Evingür, Gülşen Akin; Pekcan, Önder (Sage Publications Ltd, 2014)
The purpose of this paper is to discuss the role of multiwalled carbon nanotube in the swelling of polyacrylamide-multiwalled carbon nanotube composites. Swelling experiments were performed in water at various temperatures ...

Group behaviour in physical chemical and biological systems 

Saçlıoğlu, Cihan; Pekcan, Önder; Nanjundiah, Vidyanand (Indıan Acad Scıences, 2014)
Groups exhibit properties that either are not perceived to exist or perhaps cannot exist at the individual level. Such 'emergent' properties depend on how individuals interact both among themselves and with their surroundings. ...

Temperature effect on the swelling of PAAm-kappa-carrageenan composites 

Evingür, Gülşen Akin; Pekcan, Önder (Wiley-Blackwell, 2012)
The steady-state fluorescence (SSF) technique was used for studying swelling of disc-shaped polyacrylamide (PAAm)-kappa-carrageenan (kappa C) composites which were prepared by free-radical crosslinking copolymerization at ...

Swelling Kinetics of PAAm-kappa-Carrageenan Composites: A Fluorescence Technique 

Evingür, Gülşen Akın; Pekcan, Önder (Taylor & Francis Inc, 2011)
The steady-state fluorescence (SSF) technique was introduced for studying swelling of disc-shaped polyacrylamide (PAAm) gels containing various amount of kappa-carrageenan (kappa C). They were prepared by free-radical ...

Modelling of Swelling by the Fluorescence Technique in Kappa Carrageenan Gels 

Tari, Özlem; Pekcan, Önder (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 ...
