Application of Solid oxide proton-conducting electrolytes for amperometric analysis of hydrogen in H-2+N-2+H2O gas mixtures
(2014)Amperometric hydrogen sensors based on proton-conducting solid electrolytes of La0.95Sr0.05YO3, CaTi0.95Sc0.05O3 and CaZr0.9Sc0.1O3 compositions are prepared and investigated in the present work. The influence of the sensor ... -
Effect of wall roughness on shear viscosity and diffusion in nanochannels
(2010)The effect of wall roughness on liquid argon shear viscosity and diffusion coefficient in nanochannels is studied by non-equilibrium molecular dynamics. Diffusion coefficient results are presented in terms of average values ... -
Influence of Cu on the properties of gadolinium-doped barium cerate
(2008)In the present work the effect of copper oxide addition on the densification behavior and electrical conductivity of BaCe1-xGdxO3-delta (BCG) type ceramics is investigated. Small addition (1 mol%) of this sintering additive ... -
Novel composite solid state electrolytes on the base of BaCeO3 and CeO2 for intermediate temperature electrochemical devices
(2013)In the present work, nano-sized powders of (1-x)Ce0.8Sm0.2O2-delta-xBaCe(0.8)Sm(0.2)O(3-delta) (x = 0, 0.3, 0.5, 0.7 and 1) were obtained by solution combustion synthesis (self-combustion synthesis, SCS) method of nitrate ... -
Single phase materials based on Co-doped SrTiO3 for mixed ionic-electronic conductors applications
(2012)In the present work the effect of cobalt oxide addition on the structural and electrical properties of strontium titanate is examined. The SrTi1-xCoxO3-delta (0 <= x <= 0.4) samples were synthesized according to solid state ... -
Structural, thermomechanical and electrical properties of new (1-x) Ce0.8Nd0.2O2-delta-xBaCe(0.8)Nd(0.2)O(3-delta) composites
(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 ... -
Textured BaCe(0.5)Zr(0.3)Ln(0.2)O(3-delta) (Ln = Yb, Y, Gd, Sm, Nd and La) ceramics obtained by the aid of solid-state reactive sintering method
(2015)Dense BaCe(0.5)Zr(0.3)Ln(0.2)O(3-delta) (Ln = Yb, Y, Gd, Sm, Nd and La) proton-conducting ceramic materials are successfully prepared by solid-state reactive sintering method. The XRD analysis shows that the surface of ...
