Crystalline yttria-stabilized zirconia (YSZ) gate dielectrics have been successfully fabricated on silicon wafers. By carefully controlling the annealing condition, the crystalline YSZ gate dielectrics show promising performances following the rapid thermal annealing process. The equivalent electrical oxide thickness only increases about 2.0 Å after annealing in O2 gas, while the leakage curren...

We use spatially resolved photoelectron spectroscopy performed in operando to identify the reaction intermediates of the hydrogen electro-oxidation reaction on yttria-stabilized zirconia (YSZ) electrolytes with Pt electrodes. We find that hydroxyl on the zirconia electrolyte is a reaction intermediate in the hydrogen oxidation reaction and that it participates in the rate-determining step. In c...

Gadolinia-doped ceria (GDC) is widely used as an interlayer for preventing the formation of SrZrO3 between yttria-stabilized zirconia (YSZ) electrolyte and lanthanum strontium cobalt iron oxides (LSCF) cathode solid oxide fuel cells (SOFCs). However, diffusion Gd ions to YSZ results in decrease ionic conductivity due Gd2(Zr, Ce)2O7. In present work, we focus on lanthanum-doped (LDC) LSCF cathod...

Biaxially-textured epitaxial thin-film hetero-structures of ceria and 8 mol% yttria-stabilized zirconia (8YSZ) were grown using Pulsed Laser Deposition (PLD) with the aim to unravel the effect of the interfacial conductivity on the charge transport properties. Five different samples were fabricated keeping the total thickness constant (300 nm) but with a different number of hetero-interfaces (b...

The effect of zirconia surface treatment by mesoporous zirconia coating on the microtensile bond strength (MTBS) between zirconia and resin cement was investigated in this work. 160 zirconia specimens were prepared and divided into four groups according to surface treatments: (1) airborne-particle-abrasion treatment (APA); (2) glass infiltration and hydrofluoric acid treatment (GI+HF); (3) meso...

In this study, the effect of a thermal barrier coating with yttria-stabilized zirconia (YSZ) and aluminum silicate (Al2O3·SiO2) alongside an NiCrAl bond coat on engine performance emission analysis was evaluated by using conventional diesel pure palm oil biodiesel. These materials were coated piston alloy via plasma spray coating. The findings demonstrated that YSZ presented better performances...

Abstract High-entropy alloys (HEAs) represent a relatively new group of multicomponent that have shown great potential for applications requiring tribological and oxidation resistant properties. Consequently, thermally sprayed coatings different HEA chemistries received increasing research attention. In this paper, atomized equimolar CrFeCoNi AlCrFeCoNi feedstocks were used high velocity air-fu...

Zirconia is a widely used oxide ceramic in various high performance applications due to its attractive mechanical, electrical and thermal properties. In particular, the material 3 mol% yttria stabilized tetragonal zirconia (3YTZ) has been shown to undergo superplastic deformation [1]. One crucial step in the understanding of processes like superplasticity involves the knowledge of appropriate c...
