The broad-scale microplastic distribution in surface water and sediments along Northeastern Mediterranean shoreline
Gedik, Kenan; Eryaşar, Ahmet Raif; Öztürk, Rafet Çağrı; Mutlu, Erhan; Karaoğlu, Kaan; Şahin, Ahmet; Özvarol, Yaşar (Elsevier, 2022)Plastics manufactured to fulfil the unique demands of civilization accumulate in the sea due to their durability. Microplastics (MP) pose a greater threat than macroplastics as they can easily enter the aquatic environment ... -
Characterization of microplastic pollution in tadpoles living in small water-bodies from Rize, the northeast of Turkey
Karaoğlu, Kaan; Gül, Serkan (Pergamon-Elsevier Science Ltd, 2020)Microplastic pollution is a growing problem for Turkey and other countries, but most studies focus on the pollution in oceans and seas. To understand the relationship between microplastics, fresh water, and terrestrial ... -
Nano-sized and microporous palladium catalyst supported on modified chitosan/cigarette butt composite for treatment of environmental contaminants
Baran, Talat; Karaoğlu, Kaan; Nasrollahzadeh, Mahmoud (Elsevier, 2022)This study reports a versatile process for the fabrication of a microporous heterogeneous palladium nanocatalyst on a novel spherical, biodegradable, and chemically/physically resistant catalyst support consisting of ... -
A new fluorescent "turn-off" coumarin-based chemosensor: Synthesis, structure and Cu-selective fluorescent sensing in water samples
Karaoğlu, Kaan; Yılmaz, Fatih; Menteşe, Emre (Springer/Plenum Publishers, 2017)We report the synthesis and characterization two coumarin-based fluorescence probes, N'-{[7-(diethylamino)-2-oxo-2H-chromen-3-yl]carbonyl}pyridine-3-carbohydrazide (3) and N'-benzoyl-7-(diethylamino)-2-oxo-2H-chromene-3- ... -
Plastic occurrence in fish caught in the highly industrialized Gulf of Izmit (Eastern Sea of Marmara, Turkiye)
Aytan, Ülgen; Esensoy, Fatma Başak; Şentürk, Yasemen; Güven, Olgaç; Karaoğlu, Kaan; Erbay, Murat (Elsevier, 2023)Occurrence of micro-(<5 mm) and mesoplastics (5-25 mm) in twelve fish species caught off Gulf of Izmit in the Sea of Marmara was investigated. Plastics were found in the gastrointestinal tracks of all the analysed species: ... -
Spatiotemporal distribution of microplastics in true frogs (Ranidae: Pelophylax) populations from Turkiye
Dursun, Cantekin; Karaoğlu, Kaan; Özdemir, Nurhayat; Candan, Kamil; Kumlutaş, Yusuf; Ilgaz, Çetin; Gül, Serkan (Elsevier, 2023)Microplastics (MPs), which are of increasing concern in almost all ecosystems, continue to be an environmental threat. In the present study, the presence of MPs is investigated by using the gastrointestinal tracts (GITs) ... -
Synthesis and spectroscopic studies of homo-binuclear, alkoxo bridged homo- and hetero-tetranuclear metal complexes of a bis-N 2O 4 Schiff base ligand derived from ethanolamine and macroacyclic tetranaphthaldehyde
Karaoğlu, Kaan; Baran, Talat; Değirmencioğlu, İsmail; Serbest, Kerim (Elsevier, 2011)Three new homo-binuclear Ni(II), Cu(II), Zn(II) complexes (2-4), homo-tetranuclear Cu(II) complex (5), and hetero-tetranuclear Cu(II)-Ni(II) complex (6) of a macroacyclic potentially bis-hexadentate N 2O 4 Schiff base have ... -
