Engineering of Crystal and Domain Structures in Epitaxial Y:HfO2 Thin Films by YSZ Substrate Miscut

Advanced Science, EarlyView.
We investigate how YSZ substrate miscut influences crystal structure and domain formation in epitaxial Y‐doped HfO2 thin films. Using magnetron sputtering, high‐resolution X‐ray diffraction, atomic‐resolution scanning transmission electron microscopy, and first‐principles calculations, we systematically examine the characteristics of thickness‐ and ...

Sheet‐Size‐Dependent Mosaicity of 2D Phyllosilicate Membranes

Advanced Science, EarlyView.
This study explores how the size of 2D vermiculite sheets affects the structure of laminar membranes. High‐resolution x‐ray diffraction reveals how sheet size governs structural disorder and crystallinity. These changes directly impact ion permeability.

Preparation and application of yttrium oxide with a large specific surface area through moderate carbonation in the presence of carbon dioxide

Journal of Materials Research and Technology, 2023
Yttrium oxide with a large specific surface area (SSA) (hereafter called LSSA Y2O3) has high-porosity structure, relatively large interface, and relatively abundant active surface sites, and its optical, chemical and thermal stability properties are ...

Defect‐Engineered LiYO2 Interlayers Enabling Fast Interfacial Li+ Transport in All‐Solid‐State Batteries

Advanced Science, EarlyView.
Defect‐engineered LiYO2 interlayers are designed through aliovalent Zn2+ and Zr4+ substitution to regulate Li+ point‐defect chemistry in Ni‐rich cathodes. Compared with Li‐excess‐type LYZnO, Li‐vacancy‐type LYZrO enables faster Li+ transport, suppresses Li6PS5Cl decomposition, lowers interfacial resistance, and mitigates polarization growth, thereby ...

Influence of Y doping on high temperature oxidation resistance of titanium diboride coatings

Journal of Materials Research and Technology
In this study, DC magnetron sputtering was employed to deposit TiB2 coatings with varying yttrium content. The XPS results revealed that yttrium was identified in the TiB2 coating as yttrium oxide (Y2O3) due to the presence of residual oxygen.

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

Advanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...
