Jessima, S. J. Hepziba Magie; Subhashini, S.; Berisha, Avni; Oral, Ayhan; Srikandan, Subramanian Sathy (Elsevier B.V., 2021)

Disodium ethylenediaminetetraacetate salt is known for its excellent coordinating properties with the metal ions. The present study deals with the investigation of the prepared Disodium EDTA functionalized chitosan in ...

Isolation, Chemical Composition, Physicochemical Properties, and Antibacterial Activity of Cupressus sempervirens L. Essential Oil

Argui, Hayfa; Youchret-Zalleza, Oumayma Ben; Suner, Salih Can; Periz, Çagdas Deniz; Türker, Gülen; Oral, Ayhan; Coskun, Yalçin (Taylor and Francis Ltd., 2021)

This study was carried out to examine some of the biological activities and physicochemical properties of the Cupressus sempervirens L. essential oil (EO). C. sempervirens L. EO was isolated by hydrodistillation. GC-MS was ...

Synthesis of 1,2,3-triazole group-containing isomannide-based aromatic new polyurethanes

Bayrak, Fatih; Ay, Emriye; Oral, Ayhan; Karayıldırım, Tamer (Springer Science and Business Media Deutschland GmbH, 2022)

Ten new carbohydrate-based aromatic polyurethanes have been synthesized using isomannide and/or a new 1,2,3-triazole isomannide derivative, IV, as the diol source in the polymerization reactions. As the isocyanate source, ...

First record of straight-needle pteropod Creseis acicula Rang, 1828 bloom in the Canakkale Strait (NE Aegean Sea, Turkey)

Tuncer, Sezginer; Öǧretmen, Nazik; Çakır, Fikret; Öztekin, Alkan; Oral, Ayhan; Suner, Salih Can (De Gruyter Open Ltd, 2021)

Pteropods are marine pelagic calcifier mollusks sensitive to chemical changes in seawater due to their highly soluble aragonite shells. Increased acidity (reduced pH) of seawater causes difficulties in precipitating their ...

Synthesis And Characterization Of Novel 1,2,3-Triazole-Bridged Oxime Polyurethanes Obtained From An Isomannide Derivative

Bayrak, Fatih; Oral, Ayhan; Ay, Kadir (Macedonian Journal of Chemistry and Chemical Engineering, 2021)

Polyurethanes (PUs) are synthesized by the reaction of diisocyanates and diols and are widely used in furniture foams, thermal insulation, coatings, and adhesives. In this work, a 1,2,3-triazole-bridged dioxime (compound ...
