Efficiency of glucose oxidase immobilized on tannin modified NiFe2O4 nanoparticles on decolorization of dye in the Fenton and photo-biocatalytic processes

Immobilized enzymes are significantly studied both environmental and textile industries. In this work, glucose oxidase was immobilized on the tannin coated NiFe2O4 magnetic nanoparticles for decolorization of indigo carmin. The as-synthesized all magnetic nanoparticles were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, UV–vis spectroscopy, Thermogravimetric analysis, Vibrating sample magnetometer and Scanning electron microscopy. The activity of the free and immobilized glucose oxidase in various temperature and pH values was investigated. Finally, the produced immobilized glucose oxidase was applied for decolorization of indigo carmine due to production of H2O2. The decolorization yields of indigo carmine are 98.6% and 37.6% of the glucose oxidase immobilized on tannin modified NiFe2O4 in presence of the both of UV-light and iron(II)chloride for 90 min, respectively. The results exude that the obtained photocatalysts exhibit excellent both photocatalytic efficiency and easy separation from dye solution by an external magnet. © 2019 Elsevier B.V.Firat University Scientific Research Projects Management Unit Türkiye Bilimler AkademisiFinancial support for this work has been provided by the Scientific Research Projects Commission of Sakarya University (Project number: 2018-3-12-79).

Turkish foreign terrorist fighters and the emergence of a new kind of radicalization

This article is an attempt to answer a number of questions asked in the literature on radicalization and extremism: What motivates foreign terrorist fighters (FTFs) from Turkey to join the Islamic State of Iraq and Syria (ISIS)? In what kind of environment does violent extremism become the choice for Turkish nationals to join ISIS in Syria and Iraq? How can Turkish nationals who join ISIS be profiled in terms of their socio-economic and cultural traits and how do these traits compare people from other nations who join and fight in terrorist organizations? Though their numbers remained minimal compared to the overall population, how can we explain the case of Turkish FTFs, when a peaceful and tolerant Anatolian/Sufi Islam' has reigned in the country and Muslims are well integrated in the social, economic, and political life of the country under the 13-year long rule of Islamic-oriented Justice and Development Party (AK Party)? What do these answers to these questions mean for Turkish Islam and possible de-radicalization programs? These questions will be addressed by semi-structured interviews conducted both with Turkish FTFs who have joined ISIS and with family members of some of those who have returned from fighting with ISIS
