“…This is similar to our findings on yttria stabilized zirconia thin films [26]. The conductivities of the GDC thin films are fairly close to reports on the total (DC) conductivity of microcrystalline GDC extrapolated to lower temperatures [36], indicating that an electronic contribution is negligible [37]. The cross-plane conductivity of gadolinia doped ceria and yttria stabilized zirconia bi-layers was also investigated.…”

Furthermore, deposition at such low temperatures is promising for processing of thin film assemblies.The preparation of bi‐layer electrolytes of yttria stabilized zirconia and gadolinia doped ceria thin films by aerosol assisted chemical vapor deposition is demonstrated. Gadolinia doped ceria films as thin as 150 nm are applied as barrier layers between yttria stabilized zirconia electrolyte and La0.6Sr0.4CoO3–δ cathode in anode supported solid oxide fuel cells. High power densities above 850 mW cm–2 at 650 °C are only obtained with these barrier layers, indicating that the GDC thin films effectively inhibit the formation of unwanted interface reactions.

“…Most notable are the efforts of Shuk, Greenblatt et al who synthesized ceria particles doped with samarium, calcium, terbium, bismuth, europium, and various other metals. [136][137][138][139][140][141][142] The soft solution synthesis by Li et al 125 is also capable to produce ceria particles doped with zinc oxide or calcia, while the microwave-assisted synthesis can be used for a CeO 2 -SiO 2 composite material. 132 Azeotropic distillation, a somewhat unusual reaction type for the formation of nanoparticles, was used by Zha et al 129 In this reaction, cerium hydroxide is first precipitated along with a possible dopant metal hydroxide and then distilled in an alcoholic medium to facilitate the condensation reaction and to remove water from the system.…”

Inorganic nanoparticles with UV-absorbing properties are an important class of UV filters. They can be used in various applications and in a variety of forms, including suspensions, nanocomposites, and solid thin films. In this review, an overview of the synthetic methods and their respective products is given for the most popular UV-absorbing nanomaterials, including zinc oxide, titanium dioxide, cerium dioxide and ferrous oxides, and oxyhydroxides.

Sm 3+-doped ceria (SDC) nanopowders were prepared via a citrate co-precipitation route. The thermal decomposition of the precursor, SDC structure and morphology were investigated by thermochemical techniques (TGA/DSC), X-ray diffraction (XRD), energy dispersive spectrometer (EDS), surface area analyzer (SAA), scan electron microscopy (SEM) and transmission electron microscopy (TEM), respectively. The average crystallite size was observed to be ³7 nm when calcined at 450°C for 4 h. The effect of the ball milling treatment and relative density for the dense sintered-body were also studied. Meanwhile, dense SDC ceramics were successfully prepared by using milled powder under 1250°C and holding for 4 h. The relative density of the obtained SDC ceramics is ³99% with homogeneous microstructure and grain size is ³0.3¯m.
