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: ... -
Preparation and characterization of the highly efficient tetraphenylimidazole substituted Phthalocyanine/ZnO composite and investigation of its effect on the photocatalytic degradation of Rhodamine B and 2,4,6-trichlorophenol
Karaoğlu, Kaan; Yüzüak, Gizem Durak; Yüzüak, Ercüment; Turan, Hanife; Akçay, Hakkı Türker (Elsevier, 2024)Growing concerns about industrial waste-induced environmental degradation have driven research towards sustainable solutions.
