Far infrared properties of PbTe doped with cerium
(Elsevier Science Sa, Lausanne, 2007)
Single crystal samples of lead telluride doped with cerium were made using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 to 300K are presented. The experimental data were numerically ...
Influence of the indium concentration on microstructural and electrical properties of proton conducting NiO-BaCe0.9-xInxY0.1O3-delta cermet anodes for IT-SOFC application
(Elsevier Science Sa, Lausanne, 2013)
Optimization of the major properties of anodes based on proton conductors, such as microstructure, conductivity and chemical stability, is yet to be achieved. In this study we investigated the influence of indium on the ...
Mechanochemical synthesis of yttrium manganite
(Elsevier Science Sa, Lausanne, 2013)
Yttrium manganite (YMnO3) is a multiferroic material, which means that it exhibits both ferromagnetic and ferroelectric properties, so making it interesting for a variety of technological applications. In this work, ...
Sintering and electrical properties of Ce1-xBixO2-delta solid solution
(Elsevier Science Sa, Lausanne, 2014)
Solid solution Ce1-xBixO2-delta nanopowders with the composition of x = 0.1-0.5 were synthesized by using Self Propagating Room Temperature procedure (SPRT). The results obtained by XRPD show that synthesized samples were ...
Stability, characterization and functionality of proton conducting NiO-BaCe0.85-xNbxY0.15O3-delta cermet anodes for IT-SOFC application
(Elsevier Science Sa, Lausanne, 2014)
There are many of properties of anodes based on proton conductors, like microstructure, conductivity and chemical stability, which should be optimized. In this work we were dealing with the influence of niobium on the ...
Mechanochemically assisted solid-state and citric acid complex syntheses of Cu-doped sodium cobaltite ceramics
(Elsevier Science Sa, Lausanne, 2015)
In the last decade, the sodium cobaltite ceramic became a promising candidate for potential thermoelectric applications, because of its large thermopower and low resistivity. In this work, polycrystalline samples of ...
Magnetic properties of NiMn2O4-delta (nickel manganite): Multiple magnetic phase transitions and exchange bias effect
(Elsevier Science Sa, Lausanne, 2014)
We present magnetic properties of NiMn2O4-delta (nickel manganite) which was synthesized by complex polymerization synthesis method followed by successive heat treatment and final calcinations in air at 1200 degrees C. The ...
Improved electrical properties of Nb doped BaCe0.9Y0.1O2.95 electrolyte for intermediate temperature SOFCs obtained by autocombustion method
(Elsevier Science Sa, Lausanne, 2014)
Nb doped BaCe0.9Y0.1O2.95 (BCY) powders were synthesized by both solid state reaction (SSR) and autocombustion reaction (ACR) method to investigate how different synthesis routes influence the properties of the powders and ...
Influence of MgO addition on the synthesis and electrical properties of sintered zinc-titanate ceramics
(Elsevier Science Sa, Lausanne, 2009)
Starting mixtures of ZnO, TiO(2) and MgO (0, 1.25 and 2.5 wt.% MgO) powders were mechanically activated for 15 min in a planetary ball mill. The powders obtained were sintered non-isothermally to temperatures between 800 ...
Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier Science Sa, Lausanne, 2009)
Single crystal samples of PbTe and PbSnTe doped with Cr were made using the Bridgman technique. Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb(0.9)Sn(0.1)Te doped with 0.4 ...
