Caracterização estrutural de Perovskitas Lax-1AxCoO3 (x=0 e 0,2) ,dopadas com cálcio e bario, por espectroscopia de absorção de raios X (XAS).
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2013-09-09)
In this work, the structures of LaCoO3, La0,8Ba0,2CoO3 and La0,8Ca0,2CoO3 perovskites
were characterized as a function of temperature (LaCoO3 structure being analyzed only at
room temperature). The characterization of these ...
Carbon dioxide gas sensing properties of ordered oxygen deficient perovskite LnBaCo2O5+ı(Ln = La, Eu)
(Elsevier, 2015-07-21)
Polycrystalline samples of layered cobaltites LnBaCo2O5+ı(Ln = La, Eu) were synthesized by standardsolid state reaction. Structural, magnetic and carbon dioxide gas sensing properties of the samples werecarefully investigated. ...
