Major- and trace-element composition of olivine, perovskite, clinopyroxene, Cr-Fe-Ti oxides, phlogopite and host kamafugites and kimberlites, Alto Paranaiba, Brazil
(MINERALOGICAL ASSOC CANADA, 2008)
An integrated whole-rock petrographic and geochemical study has been carried out on kamafugites and kimberlites of the Late Cretaceous Alto Paranaiba igneous province, in Brazil, and their main minerals, olivine, clinopyroxene, ...
Study of Water-Gas-Shift Reaction over La((1-y))Sr(y)Ni(x)Co((1-x))O(3) Perovskite as Precursors
(SPRINGER/PLENUM PUBLISHERS, 2011)
The performance of La((1-y))Sr(y)Ni(x)Co((1-x))O(3) perovskites for the water gas shift reaction (WGSR) was investigated. The samples were prepared by the co- precipitation method and were performed by the BET method, XRD, ...
Study of phase stability of SrTi0.3Fe0.7O3−δ perovskite in reducing atmosphere: Effect of microstructure
(Elsevier Science, 2019-12-01)
Increasing SOFC electrode's surface area by modification of its microstructure is a well-known technique to reduce electrode polarization resistance. This is because reduced grain size and increased porosity promote diffusion ...
Influence of Cu(II) in the SrSnO3 crystallization
(Springer, 2011-11-01)
Perovskite type oxides have been intensively studied due to their interesting optical, electrical, and catalytic properties. Among perovskites the alkaline earth stannates stand out, being strontium stannates (SrSnO3) the ...

Desenvolvimento de compósitos poliméricos flexíveis com alta constante dielétrica obtidos a partir de polímeros baseados em pvdf e da perovskita ncbcto
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2018-12-19)
The objective of this thesis was to produce polymer/perovskite based composites to be used as supercapacitors; the composites were made by incorporating an specified type of perovskite (Na1/3Ca1/3Bi1/3Cu3Ti4O12, NCBCTO) ...
Lanthanum-based perovskites obtained by the polymeric precursor method
(Springer, 2008-01-01)
Cobalt oxides, specially the ones with perovskite structure, are of a high technological interest, due to their interesting optical, electrical and magnetic properties. La(1 -x)Ca(x)CoO(3) powder samples were synthesized ...
