    • Conductivity of Gd-doped BaCeO3 protonic conductor in H-2-H2O-O-2 atmospheres 

      Medvedev, D. A.; Gorbova, E. V.; Demin, A. K.; Tsiakaras, P. (2014)
      In the present investigation, a radically new and simple method of evaluation of the proton conductivity is proposed. This method is based on the conductivity measurement of ceramic materials depending on the oxygen partial ...

    • Regulatory volume decrease of rat kidney principal cells after successive hypo-osmotic shocks 

      Zarogiannis, S. G.; Ilyaskin, A. V.; Baturina, G. S.; Katkova, L. E.; Medvedev, D. A.; Karpov, D. I.; Ershov, A. P.; Solenov, E. I. (2013)
      Outer Medullary Collecting Duct (OMCD) principal cells are exposed to significant changes of the extracellular osmolarity and thus the analysis of their regulatory volume decrease (RVD) function is of great importance in ...

    • 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 ...
