PM2.5 BOUND ORGANIC MOLECULAR MARKER SPECIATION METHODS AND OBSERVATIONS FROM DAILY MEASUREMENTS IN ANKARA, TURKEY Koçak, Ebru; Kilavuz, Seda Aslan; İmamoğlu, İpek; Tuncel, Süleyman Gürdal (2017-01-01) In this study PM2.5 samples, for organic speciation, were collected at two location in the city of Ankara. One of these stations is a typical urban station close to the city center and the other one is a suburban station located in the Middle East Technical University campus. The two stations were approximately 15 km apart. Samples were collected onto prebaked quartz filters using a Hi-Vol sampler with a typical flow rate of 1.06-1.18 m(-3) min(-1). Mass concentration was determined gravimetrically by weigh...

PM3 (UHF) type quantum chemical treatment of the models for Ni-C state of [NiFe] hydrogenase from Desulfovibrio vulgaris Turker, L; Eroglu, I; Yucel, M; Gündüz, Ufuk (2004-03-01) Theoretical models based on the structure excerpted from the literature for Ni-C state of [NiFe] hydrogenase from Desulfovulgaris (Miyaszaki F) were considered. These models mainly possess either CO,CN and SO or CO,CO and SO ligands on the iron site. All the cysteinyl moieties of the models are in the amide form. In addition to the neutral forms, -/+1 charged forms of these models have been subjected to semiempirical quantum chemical analysis (PM3 (UHF)). After strict geometry optimization, certain quantum ...
PM10 and PM2.5 composition over the Central Black Sea: origin and seasonal variability Koçak, Mustafa; Tutsak, E.; Theodosi, C.; Zarmpas, P.; Kalegeri, P. (2015-11-01) Daily PM10 and PM2.5 samples were collected between April 2009 and July 2010 at a rural site (Sinop) situated on the coast of the Central Black Sea. The concentrations of PM10 and PM2.5 were 23.2 +/- 16.7 and 9.8 +/- 6.9 mu g m(-3), respectively. Coarse and fine filters were analyzed for Cl-, NO3 (-), SO4 (2-), C2O4 (2-), PO4 (3-), Na+, NH4 (+), K+, Mg2+, and Ca2+ by using ion chromatography. Elemental and organic carbon content in bulk quartz filters were also analyzed. The highest PM2.5 contribution to PM...
