Composites of yttria-stabilized zirconia (YSZ) with Sr-doped LaCrO3 (LSC) and Sr-doped LaMnO3 (LSM) were prepared by impregnation of a porous YSZ matrix with aqueous solutions of the appropriate metal salts, followed by sintering to various temperatures. XRD measurements showed that perovskite phases formed after sintering at 1073 K, a temperature well below that at which solid-state reactions ...

Nanocrystalline partially stabilised zirconia (PSZ) and yttria-fully stabilised zirconia (YSZ) powders were prepared by solution combustion process. Nanocrystalline nature of the powders was confirmed by XRD and TEM. Nanocomposite Ni/PSZ and Ni/YSZ films were electrodeposited from a suspension of nanoparticles in nickel sulfamate solution. The strengthening of the nanocomposite due to nanoparti...

Solid oxide fuel cells are promising hydrogen energy devices. The goal of this research was to create ceramic layers for SOFCs based on yttria-stabilized zirconia (YSZ) and investigate their parameters. YSZ with a thickness 5.14 ?m porous NiO–YSZ substrate 7 pyrolytic graphite were obtained by electrophoretic deposition. X-ray diffraction electron microscopy used determine the composition, stru...

Without sensing any physical force, a neutral object in an ion conducting solid can move in a uniform electrochemical fi eld by coupling a global ion wind with localized counterion diffusion at the interface. This happens to pores and gas bubbles at 840 ° C in a fast O 2– conductor, yttria-stabilized zirconia (YSZ), despite having cations that are essentially frozen with lattice diffusivities 1...

Cathodic and anodic overpotentials were measured using current interruption and AC impedance spectroscopy for two separate solid oxide fuel cells (SOFCs). The fuel cells used yttria-stabilized zirconia (YSZ) as the electrolyte, strontium-doped lanthanum manganite (LSM) as the cathode, and a porous YSZ layer impregnated with copper and ceria as the anode. The Cu/CeO2/YSZ anode is active for the ...

Evidence significant vibrational contributions the optical third order nonlinearities Yttria stabilized hafnia are reported. electronic properties YSH do not constitute subjects strong spin orbit coupling effects. This work reports for first time theoretical nonlinear susceptibilities bulk phases which key telecommunication technologies and integr...

Firstly, the yttria-stabilized zirconia (YSZ) coating and gadolinium zirconate (GZO) with quasi-columnar structure were manufactured by plasma spray physical vapor deposition. At same time, a novel three-dimensional geometrical model was established that could satisfactorily reflect such structural characteristics. Then, based on this model, spatial distribution of pores porosity coatings therm...

In order to apply high-Tc material to a real accelerator cavity, it may be indispensable that the material is deposited on metal substrate. It is now possible to align the c axis of YBa2Cu3Oy (YBCO) film perpendicular to a metal surface. Furthermore, the constituent crystals can be in-plane aligned with a laser ablation technique following the formation of yttria-stabilized-zirconia (YSZ) buffe...

In this work, we show the epitaxial growth of (111)-oriented EuTiO3 thin films on (001)-oriented silicon with an in situ grown yttria-stabilized zirconia (YSZ) buffer layer by pulsed laser deposition. X-ray diffraction measurements revealed a homogeneously strained film strain dependency fluence during growth. From magnetization vs temperature measurements, confirmed that have antiferromagnetic...
