    Defect structure of zirconium oxide nanosized powders with Y2O3, Sc2O3, Cr2O3 impurities
    (Видавництво Львівської політехніки, 2012) Yurchenko, L.; Bykov, I.; Vasylyev, A.; Vereshchak, V.; Suchaneck, G.; Jastrabik, L.; Dejneka, A.
    Formation mechanisms of paramagnetic centers originating from Zr3+ and Cr3+ ions as well as the influence of composition of nanoparticles on thermogeneration processes of these paramagnetic centers in ZrO2 structure were studied. A set of nanosized powders of zirconium oxide was investigated by electron paramagnetic resonance method: nominally pure ZrO2; ZrO2 with Y2O3 and Sc2O3; ZrO2 with Cr2O3; ZrO2 with Y2O3 and Cr2O3. It is observed that the influence of annealing on EPR lines of Zr3+ and Cr3+ions is different. Nuclear magnetic resonance data have shown that zirconium dioxide nanoparticles with Sc and Y impurities include two types of water molecules and two types of hydroxyl groups.

    Fractal analysis of surface topography of solid oxide fuel cell materials
    (Видавництво Львівської політехніки, 2012) Suchaneck, G.; Ponomareva, A. A.; Brychevskyi, M.; Brodnikovskyi, I.; Vasylyev, O.; Gerlach, G.
    In this work, we investigate the hierarchical surface topography of solid oxide fuel cell electrolytes consisting of zirconia stabilized with 10% Sc2O3 and 1% CeO2 (1Ce10ScSZ) synthesized at 1300-1400 °C and anodes of 60 wt% 1Ce10ScSZ and 40 wt% NiO synthesized at 1250 to 1550 °C. The fractal dimension of AFM images of the films was determined by the cube counting method, the triangulation method and by means of the PSD slope at large wavenumbers. RMS roughness and correlation lengths were derived from the fit to the model PSD.
