An asymmetric lanthanum doped ceria (LDC) membrane was prepared by sintering process. The membrane consisted of two layers, dense LDC and porous Ni-LDC layers with a total thickness of approximately 850 μm. According to the XRD pattern, sintering process... see more

It is demonstrated that the synthesis procedure for preparing three-dimensionally ordered macroporous (3DOM) Pr-doped ceria catalysts using a polymethylmethacrylate (PMMA) template not only affects the porous structure, but also the chemistry of the ceria... see more

Ceria supported metal catalysts often exhibit high activity in the preferential oxidation (PROX) of CO in H2-rich stream and doping the ceria support with other metals proves to be rather effective in further enhancing their catalytic performance. Therefo... see more

Mono metallic and bimetallic Pd (1 wt. %)–Au (3 wt. %) catalysts were prepared using two ceria supports doped with 1 wt. % Y2O3. Yttrium was added by impregnation or co-precipitation. The catalyst synthesis was carried out by deposition–precip... see more

Lanthanum ferrite (LaFeO3) and silver doped LaFeO3 powders were synthesized by a single step microwave combustion route using nitrates as precursors and glycine as a fuel. XRD analysis indicated the formation of cubic phase with the dopant peaks at 2? val... see more

Oxygen vacancy diffusion in yttria-doped ceria (YDC) and yttria-stabilized zirconia(YSZ) are investigated using statistical moment method, including the anharmonicity effects of thermal lattice vibrations. The expressions of oxygen vacancy-dopant associat... see more

Sm0,20Ce0,80O2 powder was used for the formation of samarium doped cerium oxide (SDC) thin films using e-beam. Surface area of powder was 34.9 m2/g and particle size – 0.3-0.5 µm. Thin films were deposited using physical vapor deposition system on SiO2 an... see more

The creation of new non-toxic materials that combines high osteointegration and strength characteristics is an urgent contemporary challenge. The use of complex oxides, such as lanthanum zirconate (La2Zr2O7), as non-reservable alloplastic implant material... see more
