Electrode reaction of Sr1-xLaxCo0.8Fe0.2 O3-δ with x = 0.1 and 0.6 on Ce0.9Gd0.1O1.95 at 600 ≤ T ≤ 800 °C
(Elsevier Science, 2006-03)
The electrode reaction of the perovskite phases Sr1-xLaxCo0.8Fe0.2O 3-δ (x = 0.1 and 0.6) on Ce0.9Gd0.1O1.95 has been investigated by impedance spectroscopy in the temperature range 600 ≤ T ≤ 800 °C. Thick porous electrodes ...
Probing phase coexistence and stabilization of the spin-ordered ferrimagnetic state by calcium addition in the Y (Ba1-x Cax) Co2 O5.5 layered cobaltites using neutron diffraction
(American Physical Society, 2007-12)
We study the effects of a partial substitution of Ba with the smaller cation Ca in the layered cobaltites YBa Co2 O5+δ for δ≈0.5. Neutron thermodiffractograms are reported for the compounds Y Ba0.95 Ca0.05 Co2 O5.5 (xCa ...
Non-one-dimensional behavior in charge-ordered structurally quasi-one-dimensional Sr6Co5O15
(American Physical Society, 2011-05-19)
We have synthesized Sr6Co5O15, a quasi-one-dimensional oxide, measured its magnetic properties, and calculated its electronic structure by ab initio techniques. We have found strong evidence for its electronic and magnetic ...
Effects on the physical properties of cation substitution in the layered cobaltites Y (Ba1 - x Cax) Co2 O5.5
(Elsevier Science, 2007-09)
In this work we study the physical properties of the layered cobaltites YBaCo2 O5.5, focussing on the role of cationic disorder and size effects by a partial substitution of Ba by Ca. We have synthesized the polycrystalline ...
Co3(SO4)3(OH)2[enH 2]: A New S = 3/2 kagome-type layered sulfate with a unique connectivity
(American Chemical Society, 2009-09)
The versatile method of structure-directed synthesis in a sulfuric acid system for the preparation of novel metal sulfates including those with structures comprising vertex-linked M(O,F)6 octahedra with a Kagome topology ...
La/Ba-based cobaltites as IT-SOFC cathodes: a discussion about the effect of crystal structure and microstructure on the O2-reduction reaction
(Pergamon-Elsevier Science Ltd, 2016-10)
This work discusses the effect of the crystal structure and microstructure on the electrocatalytic activity of Lanthanum-Barium cobaltite (LBC), evaluatedas IT-SOFC cathode. Two systems with similar microstructures (particle ...
Rate limiting steps of the porous La0.6Sr0.4Co0.8Fe0.2O3-δ electrode material
(Elsevier Science, 2009-11)
The electrode reaction of porous La0.6Sr0.4Co0.8Fe0.2O3-δ films deposited onto Ce0.9Gd0.1O1.95 (CGO) was investigated by impedance spectroscopy within the temperature and oxygen partial pressure (pO2) ranges of 500 ≤ T ≤ ...
Carbon dioxide sensing properties of bismuth cobaltite
(2011)
Bismuth cobaltite with sillenite-type structure was prepared from Co(OH)2 and Bi(NO3)3·6H2O through solid state reaction at 600 °C. Neutron powder diffraction (NPD) data and X-ray absorption spectroscopy revealed the ...
