      Ananyev, M.; Medvedev, D.; Gavrilyuk, A.; Mitri, S.; Demin, A.; Malkov, V.; Tsiakaras, P. (2014)
      Segmentation algorithms for the quantitative description of the surface microstructure and the evaluation of the grain-boundary conductivity of ceramic materials surface using SEM microphotographs analysis was developed ...
    • EPR STUDY OF Ti-Si-C-N SYSTEM 

      Guskos, N.; Anagnostakis, E. A.; Zolnierkiewicz, G.; Typek, J.; Biedunkiewicz, A.; Figiel, P.; Guskos, A.; Karkas, K. A. (2010)
      Nanocrystalline (TiC(x) + SiC)/C (sample 1) and TiC(0.3)N(0.7) + SiC + Si(3)N(4) (sample 2) materials were prepared by the non-hydrolytic sol-gel method. Sample 2 was obtained from sample 1 by annealing in an NH(3) atmosphere ...
    • Structural, thermomechanical and electrical properties of new (1-x) Ce0.8Nd0.2O2-delta-xBaCe(0.8)Nd(0.2)O(3-delta) composites 

      Medvedev, D.; Pikalova, E.; Demin, A.; Podias, A.; Korzun, I.; Antonov, B.; Tsiakaras, P. (2014)
      In this work composite (1-x)Ce0.8Nd0.2O2-delta-xBaCe(0.8)Nd(0.2)O(3-delta) ceramics were prepared via the one-step citrate-nitrate combustion procedure, and characterised by TG-DSC, XRD analysis, and SEM. Their transport ...
    • Thermal expansion of materials in the barium cerate-zirconate system 

      Lyagaeva, Y. G.; Medvedev, D. A.; Demin, A. K.; Tsiakaras, P.; Reznitskikh, O. G. (2015)
      The thermal expansion of proton-conducting materials in the BaCe0.8 - x Zr (x) Y0.2O3 - delta system has been investigated in air. The influence of the zirconium concentration and the measurement mode (heating/cooling) on ...
