The flaxseed gum based edible film was prepared and investigated for dynamic mechanical properties and water vapor transmission rate in this study. The glass transition temperature of the films, indicated by the peak of tan delta, was significantly decreased by the increasing of the glycerol concentration. The storage modulus and the temperature at which it reached a maximum value were decreased by the increasing of the glycerol concentration. The glass transition temperature of the flaxseed gum based edible films was also increased by the increasing of the flaxseed gum concentration. The increasing of the glycerol and flaxseed gum concentration could lead to the increase of water vapor transmission rate of the flaxseed gum films.

Nanocomposites based on recycled poly(ethylene terepthalate) Tolga, Aslı; Yılmazer, Ülkü; Department of Chemical Engineering (2005) In this study, the effects of glycol type, organoclay type and concentration on the final properties of nanocomposites based on recycled poly(ethylene terephthalate) was investigated. For this purpose, first recycled PET was glycolysed and after that unsaturated polyester-montmorillonite nanocomposites were synthesized by using three different types of glycols (i.e. ethylene glycol (EG), propylene glycol (PG) and diethylene glycol (DEG)). As the first step, all the compositions were prepared by Cloisite 30B...
Microwave-Assisted Extraction of Phenolic Compounds from Caper DURMAZ, Ezgi; Şümnü, Servet Gülüm; Şahin, Serpil (2015-09-02) In this study, it was aimed to extract phenolic compounds from caper by using microwave and to compare the results with conventional extraction. For microwave-assisted extraction, power, extraction time, solid to solvent ratio, and solvent type were selected as independent variables. Dependent variables were total phenolic content (TPC), antioxidant activity, and concentration of phenolic compounds. The increase in solvent amount increased TPC. The highest TPC was obtained by using extraction conditions of ...
Nanoclay and carbon nanotubes as potential synergists of an organophosphorus flame-retardant in poly(methyl methacrylate) Isitman, Nihat Ali; Kaynak, Cevdet (2010-09-01) This study explores whether nanoparticles incorporated in polymers always act as synergists of conventional flame-retardant additives. For this purpose, two different filler nanoparticles, namely organically modified layered-silicate clay minerals or nanoclays and multi-walled carbon nanotubes, were incorporated in poly(methyl methacrylate) filled with an organophosphorus flame-retardant that acts through intumescence. Effective dispersion techniques specific to each nanoparticle were utilized and prepared ...
Comparison of microwave and ultrasound-assisted extraction techniques for leaching of phenolic compounds from nettle Ince, Alev Emine; Şahin, Serpil; Şümnü, Servet Gülüm (2014-10-01) In this study, extraction of phenolic compounds from nettle by microwave and ultrasound was studied. In both microwave and ultrasound-assisted extractions, effects of extraction time (5-20 min for microwave; 5-30 min for ultrasound) and solid to solvent ratio (1:10, 1:20, and 1:30 g/mL) on total phenolic content (TPC) were investigated. Effects of different powers (50 % and 80 %) were also studied for ultrasound-assisted extraction. In microwave-assisted extraction, the optimum TPC of the extracts (24.64 +/...
Dynamic mechanical analysis of provisional resin materials reinforced by metal oxides Korkmaz, T; Doan, A; Usanmaz, Ali (2005-01-01) In this study, several provisional resin materials were investigated by dynamic mechanical analysis (DMA). The materials were autopolymerized PMMA and PEMA, light cured PMMA. Autopolymerized PMMA has the highest T-g (131 degrees C) compared to that of the autopolymerized PEMA (102 degrees C) and light cured PMMA (120 degrees C). The storage moduli for autopolymerized PMMA, autopolymerized PEMA and light cured PMMA are 2.9, 1.8 and 2.3 GPa, respectively. The loss moduli of the same resins are 330, 300 and 35...
