Modification of Saharan dust size distribution during its transport over the Anatolian Plateau
Uzunpınar, Elif Sena; İmamoğlu, İpek; Rahmani, Amir; Tuncel, Süleyman Gürdal (2023-09-20)
Particle number size distribution in dust plumes and its modification as the plume travels over the Anatolia were investigated by measuring particle number size distributions at two stations: one located on the Mediterrane...
Novel catabolic pathway for 4-Nitroaniline in a Rhodococcus sp. strain JS360
Kurt, Zöhre; Qu, Yi; Spain, Jim C. (2023-07-15)
4-Nitroaniline (4NA), the starting material for the first synthesized azo dye, is a toxic compound found in industrial wastewaters. Several bacterial strains capable of 4NA biodegradation were previously reported but the d...
Seasonal monitoring of microbial activity using conventional approaches in a full-scale urban biological wastewater treatment plant
Demirbilek, Deniz; İpek, Ubeyde; Yetiş, Ülkü (2023-05-01)
Activated sludge processes contain various groups of microorganisms with different metabolic properties, which are responsible for contaminants removal. Therefore, it is important to elucidate the general structure and fun...
Preparation of chabazite based Fenton-like heterogeneous catalyst and its organic micropollutant removal performance
Ali, Mohsin; Dilek, Filiz Bengü; İpek Torun, Bahar (2023-04-01)
Natural chabazite (CHA) is used for the first time as a heterogeneous catalyst in Fenton-like oxi- dation. Pretreatment techniques (NH4+-exchange, steam treatment, and Fe-exchange) were ap- plied to natural CHA to improve ...
