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 ...
Evidence of improvement in gas sensing properties of nanostructured bismuth cobaltite prepared by solution-polymerization method
(2007)
Polycrystalline powders of bismuth cobaltite, Bi10Co16O38, with sillenite-type structure were prepared by solid-state reaction, solution and solution-polymerization methods, followed by calcination at 600 °C. By the ...
Low-temperature magnetic behavior of the rare-earth cobaltites GdCoO 3 and SmCoO3
(2007)
The temperature and magnetic field dependences of the static magnetization of the polycrystalline rare-earth cobaltites GdCoO3 and SmCoO 3 have been measured. It is shown that, below room temperature, the magnetization of ...
The Soft Chemical Route Improving IT-SOFC Cathode Performance: The Lanthanum Barium Cobaltite Case
(Electrochemical Society, 2013-10)
In this work we studied the oxygen reduction mechanism in three cathodes: cubic La0.5Ba0.5CoO3-δ obtained by Solid State Reaction (SSR) in air at 1100 ºC; a phase with cationic order, laminar structure and tetragonal ...
Catalytic Properties of Double Substituted Lanthanum Cobaltite Nanostructured Coatings Prepared by Reactive Magnetron Sputtering
(Multidisciplinary Digital Publishing Institute, 2019-04)
Lanthanum perovskites are promising candidates to replace platinum group metal (PGM), especially regarding catalytic oxidation reactions. We have prepared thin catalytic coatings of Sr and Ag doped lanthanum perovskite by ...
Transport mechanism through metal-cobaltite interfaces
(American Institute of Physics, 2016-07)
The resistive switching (RS) properties as a function of temperature were studied for Ag/La(1−x)SrxCoO3 (LSCO) interfaces. The LSCO is a fully relaxed 100 nm film grown by metal organic deposition on a LaAlO3 substrate. ...
Effect of Nb5 + content on the high temperature properties of the mixed conductors system La1 − xBaxCo1 − yNbyO3 − δ with 0.6 ≤ x ≤ 1.0 and 0 ≤ y ≤ 0.4
(Elsevier Science, 2017-02)
The replacement of Co by Nb in the La1 − xBaxCo1 − yNbyO3 − δ (0.6 ≤ x ≤ 1.0) system and its effects on phase stability and high temperature properties of the cubic perovskite phase were investigated by X-ray diffraction, ...
Structural, electrical and magnetic properties of epitaxial La 0.7 Sr 0.3 CoO 3 thin films grown on SrTiO 3 and LaAlO 3 substrates
(Elsevier Science, 2014-03)
La 0.7 Sr 0.3 CoO 3 (LSCO) thin films have been epitaxially grown on SrTiO 3 (STO) and LaAlO 3 (LAO) substrates by metal organic deposition. The effects of the strain - induced by clamping - on the structural and physical ...
