Antimicrobial activity and chemical composition of coriander & galangal essential oil
Özkınalı, Sevil; Şener, Nesrin; Gür, Mahmut; Güney, Kerim; Olgun, Çağrı (Association of Pharmaceutical Teachers of India, 2017)Essential oils were obtained from Coriandrum sativum and Alpinia officinarum through steam distillation method in this study. Antimicrobial activities of the obtained essential oils were investigated by using minimum ... -
Chromate-selective electrodes prepared by using calix[4]arenes for the speciation of Cr(VI) and Cr(III)
Dalkıran, Berna; Kormalı Ertürün, H. Elif; Demirel Özel, Ayça; Canel, Esin; Özkınalı, Sevil; Kılıç, Esma (Institute for Ionics, 2017)The calix[4]arene and its mono-, di-, tri-, and tetra-acryloyl esters were used as suitable ionophores for Cr(VI) species to develop poly(vinyl chloride) (PVC) membrane electrodes. The influence of membrane contents and ... -
