Journal ArticleDOI
Ceria based mixed conductors with adjusted electronic conductivity in the bulk and/or along grain boundaries
Duncan P. Fagg,Domingo Pérez-Coll,Pedro Núñez,Jorge R. Frade,Aliaksandr L. Shaula,Aleksey A. Yaremchenko,Vladislav V. Kharton +6 more
TL;DR: In this article, the authors used de-convolution of impedance spectra to identify changes in grain boundary properties, which can be used to tune preferential electronic conductivity at bulk or grain boundary level.
Journal ArticleDOI
Electrical Conductivity, Thermal Expansion and Electrochemical Properties of Perovskites PrBaFe2–xNi x O5 + δ
TL;DR: In this article, the authors evaluated the applicability of mixed-conducting PrBaFe2−xNi perovskites for cathodes of solid oxide fuel cells (SOFCs), their crystal structure, thermal and chemical expansion, electrical conductivity and electrochemical behavior were studied.
Journal ArticleDOI
Processing and oxygen permeability of asymmetric ferrite-based ceramic membranes
Andrei V. Kovalevsky,Vladislav V. Kharton,Frans Snijkers,J.F.C. Cooymans,Jan Luyten,Jorge R. Frade +5 more
TL;DR: In this paper, a series of planar ceramic membranes with dense layers made of the dual-phase (SrFeO 3−− δ ) 0.3 composite were appraised at 1023-1223 K under oxidizing conditions.
Journal ArticleDOI
Defect formation, ordering, and transport in SrFe 1–x Si x O 3–δ ( x = 0.05–0.20)
O.V. Merkulov,Eugene N. Naumovich,Mikhail V. Patrakeev,Alexey A. Markov,E. V. Shalaeva,Vladislav V. Kharton,Ekaterina V. Tsipis,João C. Waerenborgh,I. A. Leonidov,V.L. Kozhevnikov +9 more
TL;DR: In this paper, a model accounting for anion site-exclusion effects near highly stable SiO4 tetrahedra and energetic favorability of the defect clusters formed by two tetrahedral sharing one oxygen vacancy was proposed.
Journal ArticleDOI
Oxygen nonstoichiometry of Bi2V0.9Cu0.1O5.5−δ solid electrolyte by coulometric titration technique
V.N. Tikhonovich,E.N. Naumovich,Vladislav V. Kharton,Vladislav V. Kharton,Aleksey A. Yaremchenko,Aleksey A. Yaremchenko,Andrei V. Kovalevsky,A.A. Vecher +7 more
TL;DR: In this article, the authors used the coulometric titration technique and thermogravimetric analysis at oxygen partial pressures from 1×10 −7 to 0.5 atm (atmospheric air) in the temperature range 650-1050 K.
