Aqueous solutions of calcium chloride (CaCl2.2H(2)O) and zirconium oxychloride (ZrOCl2.8H(2)O), in appropriate volumetric amounts, were used as the starting chemicals in the synthesis of phase-pure CaZrO3 powders. Rare earth element dopings (up to 25 at%) were performed by using the aqueous chloride solutions of gadolinium (Gd). Formation of CaZrO3 powders were achieved by two different chemical synthesis techniques: (i) self-propagating combustion synthesis, and (ii) precipitation in the presence of EDTA by the technique of acid-base titration. Sample characterization was performed by powder XRD (Xray diffraction) and SEM (scanning electron microscope).

Spectroelectrochemical investigation of the anodic oxidation of dibenzo-18-crown-6 Cihaner, A; Önal, Ahmet Muhtar (Elsevier BV, 2004-10-01) Poly(dibenzo-18-crown-6) (poly-DB18C6) was synthesized by electrochemical oxidation of dibenzo-18-crown-6 (DB18C6) using a mixture of acetonitrile and dichloromethane as the solvent and tetrabutylammonium tetrafluoroborate (TBABF(4)) or tetrabutylammonium hexafluorophosphate (TBAPF(6)) as supporting electrolyte. The anodic polymerization of DB18C6 was investigated using in situ ESR and in situ UV-Vis spectroscopic techniques. Spectroelectrochemical (SPEL), properties and thermal analysis of the resulting po...
Surfactant modified zinc borate synthesis and its effect on the properties of PET Baltaci, Berk; ÇAKAL, GAYE ÖZGÜR; Bayram, Göknur; Eroglu, Inci; Özkar, Saim (Elsevier BV, 2013-08-01) Zinc borate was prepared from the reaction of zinc oxide and boric acid in the absence or presence of cumene terminated poly(styrene-co-maleic anhydride), PSMA, added as a surfactant at varying concentrations (0.1-1 wt.% of water) to the reaction medium to investigate its effect on the growth and agglomeration of particles during reaction. Synthesized zinc borates were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA) in comparison to unmodifie...
Electrochemical polymerization of 9-fluorenecarboxylic acid and its electrochromic device application Bezgin, Buket; CİHANER, ATİLLA; Önal, Ahmet Muhtar (Elsevier BV, 2008-09-01) Poly(9-fluorenecarboxylic acid) (PFCA) was synthesized by electrochemical oxidation of 9-fluorenecarboxylic acid (FCA) using a mixture of nitromethane and boron trifluoride diethyl etherate as the solvent and tetrabutylammonium tetrafluoroborate as the supporting electrolyte. An insoluble and conducting brownish-orange film was deposited on the electrode surface, both during repetitive cycling and constant potential electrolysis at 1.15 V. Characterization of the polymer film has been carried out using Four...
