Activated carbon adsorption of fuel oxygenates MTBE and ETBE from water

İnal, Fikret; Yetgin, Senem; Aksu, Gülsüm T.; Şimşek, Selvi; Sofuoğlu, Aysun; Sofuoğlu, Sait Cemil (Springer, 2009-11)

The aqueous phase adsorption of fuel oxygenates methyl tertiary butyl ether (MTBE) and ethyl tertiary butyl ether (ETBE) onto commercially available granular activated carbon (GAC; Norit GAC 1240) was investigated in a ...

Calf thymus DNA characterization and its adsorption on different silica surfaces

Yetgin, Senem; Balköse, Devrim (Royal Society of Chemistry, 2015)

DNA adsorption is the initial stage of gene therapy for drug delivery systems and solid phase extraction methods of DNA purification. High pore volume and high adsorption capacity are simple requirements not only for ...

DNA adsorption on silica, alumina and hydroxyapatite and imaging of dna by atomic force microscopy

Yetgin, Senem (Izmir Institute of Technology, 2013)

The scope of the study is to investigate calf thymus DNA adsorption process on solid powders such as silica, alumina and hydroxyapatite (HAP) to improve DNA solid phase extraction efficiency and to visiulize DNA adsorption ...

Flexible PVC-Silica composites as an adsorptive material for water soluble dyes

Ulutan, Sevgi; Yetgin, Senem; Balköse, Devrim (Smithers Rapra Technology, 2013)

Methylene Blue (MB) adsorption studies were performed on flexible Polyvinyl Chloride/Silica composites which were obtained by using plastisol-plastigel technology. Change of MB concentration in aqueous phase as the adsorption ...

Investigation of fuel oxygenate adsorption on clinoptilolite rich natural zeolite

Yetgin, Senem (Izmir Institute of Technology, 2006)

The wide use of fuel oxygenates in gasoline as anti-knocking and emission reduction agent have recently led to serious environmental concerns due to their detection in groundwater and surface water. Among the various ...

Methylene blue adsorption from aqueous solutions to flexible poly(vinyl chloride) silica composites

Yetgin, Senem; Ulutan, Sevgi; Balköse, Devrim (Wiley, 2015-03)

Methylene blue (MB) adsorption studies were performed with poly(vinyl chloride)-(dioctyl phthalate)-silica composites, which were obtained by using plastisol-plastigel technology. The films were flexible, having elastic ...

Morphology of sodium salt of calf thymus DNA on mica, alumina, and silica surfaces: Effect of solvent and drying method

Yetgin, Senem; Balköse, Devrim (Taylor & Francis, 2017-06)

Investigation of morphology of deoxyribonucleotide triphosphate (DNA) dried on different surfaces by atomic force microscopy (AFM) is important in DNA research that is focused on subjects of condensation for gene therapy, ...

Optical and surface properties of zinc oxide nanoparticles dried by conventional and supercritical ethanol drying techniques

Egbuchunam, Theresa Obuajulu; Yetgin, Senem; Özmıhçı Ömürlü, Filiz; Balköse, Devrim (Research India Publications, 2014)

Zinc oxide (ZnO) nanoparticles were synthesized by conventional (ZnO-A) and supercritical ethanol drying (ZnO-B). Nitrogen adsorption/desorption analyses were performed to determine the surface areas of the powders. The ...

Preparation and characterization of flexible poly(vinyl chloride) foam films

Şahin, Erdem; Yaşar Mahlıçlı, Filiz; Yetgin, Senem; Balköse, Devrim (Wiley, 2012-07)

In this study, the effect of activator ZnO and heating time at 190°C on foaming, gelation, and dehydrochlorination of poly(vinyl chloride) (PVC) plastisol was investigated. For this purpose, a PVC plastisol was prepared ...

Preparation and characterization of flexible polyvinylchloride-copper composite films

Kurt, Emrah; Özçelik, Cenk Yağız; Yetgin, Senem; Özmıhçı Ömürlü, Filiz; Balköse, Devrim (Smithers Rapra Technology, 2013)

Flexible PVC films are statically charged due to their low electrical conductivity. This creates fire threat during its handling. Conductive materials are added to films to prevent this. In the present study it was aimed ...
