This paper deals with the morphology, constitutive phases and fine microstructures of some EBPVD processed yttria partially stabilized zirconia thermal barrier coatings. This study has been performed by X-ray diffraction and scanning and transmission electron microscopy. It was shown that the coatings studied were constituted of a single metastable tetragonal t' phase, as expected if one refers...

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...

This study investigates the catalytic activity for soot combustion of Ag nanoparticles dispersed on various supports showing different redox properties. Temperature programmed oxidation and isotopic exchange experiments were performed to assess impact soot/catalyst contact, oxygen partial pressure ageing toward activity. Three contact modes have been used clearly highlight performances: loose, ...

Atomic force microscopy and electron microscopy with energy dispersive X-ray analysis was used to characterize changes in teh structure and composition of La0.8Sr0.2MnO3 (LSM) nanoparticles supported on single crystal YSZ (100) (yttria-stabilized zirconia) and SrTiO3(100) surfaces as a function of temperature and exposure to oxidizing and reducing environments. On YSZ(100), LSM particles were f...

• The NLO capacity of YSZ is comparable to YSZ. 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...

Diierent bounds on the conductivity of a composite material may improve on each other in diierent conductivity regimes. If so, the question arises of how to eeciently interpolate between the bounds. In this paper we show how to do an interpolation with a two-point Pad e approximation method. For bounds on two-component composites the interpolation method is shown to be, in a sense, the best pos...

Hydroxyapatite (HA) coatings on metallic implants have been extensively used in orthopedic applications to improve tissue-implant interactions, enhance their biocompatibility, and functionality. However, the expensive synthetic HA is most widely bioceramic for implant coatings, leading high costs. Hence, this research explored potential of an inexpensive biogenic derived from fish scales FsHA/y...

a r t i c l e i n f o Using first-principles calculations, we have carried out a systematic comparative study of the microscopic atomic defect configurations in cubic and tetragonal yttria-stabilized zirconia (YSZ) and their correlation with the macroscopic lattice parameters and relative phase stability, as a function of Y concentration. We found that Y atoms sit at the second-nearest-neighbor...
