Composite materials frequently allow the drawbacks of single components to be overcome thanks to a synergistic combination of material- and structure-specific features, leading to enhanced and also new properties. This is the case of a metallic-ceramic composite, a nickel-chromium-aluminum (NiCrAl) foam impregnated with La-doped Strontium...

Transport and structural properties of heavily doped ceria can reveal subtle details of the interplay between conductivity and defects aggregation in this material, widely studied as solid electrolyte in solid oxide fuel cells. The ionic conductivity of heavily Gd-doped ceria samples (Ce1−xGdxO2−x/2 with x ranging between 0.31 and 0.49) was...

The structural and electrochemical properties of Sr1-xNaxSiO3were studied. Powders with different compositions (0.1 ≤ x ≤ 0.45) were prepared by solid state reaction. Mixing of SrCO3, Na2CO3and SiO2was carried out in different media in order to explore the effect of solvents on the formation of secondary phases. X-ray diffraction was employed...

An experimental investigation of the crystallographic, Raman and transport properties of the Ce1−x(Nd0.74Tm0.26)xO2−x/2 (0.1 ≤ x ≤ 0.6) doped ceria system was performed with the aim of setting out correlations between structural features and ionic conductivity of the material. The chosen composition ensures that the average size of the Nd3+ and...
