recommendations! Published in 2018 at "Ceramics International"

DOI: 10.1016/j.ceramint.2018.04.210

Abstract: Abstract Doped CeGdO and codoped CeGdOSmO compositions were synthesized, giving rise to nanoparticulate powders. Ionic conductivities at bulk and grain boundaries of the sintered samples were determined, exhibiting increased conductivity in the samaria-codoped samples. Scanning… read more here.

DOI: 10.1016/j.jpowsour.2020.229118

Abstract: Abstract Fluorite-doped Gd0.1Ce0.9O1.95 (GDC) polycrystalline electrolytes (Gd0.1Ce0.9-xCaxF2xO1.95-2x, x = 0.00–0.10) have been synthesized for the first time, which have the same concentration of oxygen vacancies as GDC but show extraordinarily enhanced oxide ionic conductivities, along with suppressed… read more here.

DOI: 10.3938/jkps.75.293

Abstract: The ionic conductivities of yttria-doped ceria (YDC) and yttria-stabilized zirconia (YSZ), are investigatied using statistical moment method including the anharmonicity effects of thermal lattice vibrations. The expressions for the lattice constant and the vacancy activation… read more here.
