Sorption and slow release kinetics of PAAM gels at various temperatures
(Freund Publishing House Ltd, 2007-11)
Small molecule sorption and slow release in and out of polyacrylamide (PAAm) gels were studied by using steady state fluorescence (SSF) technique. Pyranine (P-y) dissolved in water used as a probe. Fluorescence emission ...
Cementation characteristics and age of beachrocks in a fresh-water environment, Lake Iznik, NW Turkey
(Elsevier Science BV, 2012-12-01)
This paper focuses on the cement characteristics and optical luminescence age of late Pleistocene-Holocene beachrock, exposed on the southeast shore of freshwater Lake Iznik in northwest Turkey, based on field observations, ...
Universality of sol-gel phase transition of kappa-carrageenan in various salts: a steady state fluorescence study
(Taylor & Francis Ltd, 2007-08)
Thermal phase transitions of kappa-carrageenan in NaCl, KCl and CaCl2 solutions were studied using steady state fluorescence (SSF) technique. Pyranine was introduced as a fluorescence probe for studying sol-gel phase ...
Differential uplift along the northern margin of the Central Anatolian Plateau: inferences from marine terraces
(Pergamon-Elsevier Science LTD, 2013-12-01)
Emerged marine terraces and paleoshorelines along plate margins are prominent geomorphic markers that can be used to quantify the rates and patterns of crustal deformation. The northern margin of the Central Anatolian ...
Critical behavior of thermal phase transitions of iota-carrageenan in CaCl2 solution
(Elsevier B.V., 2006-07-15)
In situ photon transmission method was applied to study thermal phase transitions of ?-carrageenan in CaCl2 solution. Coil-to-helix (c-h) and helix-to-dimer (h-d) transitions were detected upon cooling. An extra dimer-to-dimer ...
A phase diagram near the NAC point in liquid crystals
(Elsevier Science SA, 2002-07-28)
In this study using a mean field model we obtain the phase line equations for the NA. NC and AC transitions near the NAC point in a mixture of liquid crystals. We then fit these phase line equations to the experimental ...
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 ...
Effects of annealing on morphology of polymer/polymer (PS/PMMA) blend; a fluorescence study
(John Wiley& Sons Inc, 2006-05-05)
Steady state fluorescence (SSF) technique conjunction with optical microscopy were used to study the morphology of polystyrene (PS)/poly(methyl methacrylate) (PMMA) blend upon annealing above glass transition in elevated ...
Aeolian imprints of multiple Mediterranean invasions of the Black Sea during Pleistocene
(Elsevier B.V., 2022-03-04)
Climate changes determined the repeated connections between the Black Sea, Caspian Sea and Mediterranean Sea. The landlocked anoxic Black Sea basin was exposed to several transgressions throughout Quaternary by the ...
Vapor-induced film formation from low-T-g particles for different solvent compositions
(Elsevier Inc, 2006-05-15)
The photon transmission method was used to study latex film formation from poly(vinyl acetate) (PVAc) particles induced by two different solvents. Films with the same latex content were prepared from PVAc particles and ...
