The Derivation of Crystal Orientation Matrix for Triclinic System on Two-circle Diffractometer

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
 The limited availability of the two-circle diffractometer to collect intensity measurements down to the monoclinic system has been extended in a novel procedure to collect intensities for the triclinic system.

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 ...

Interlayer‐Sliding‐Enabled Multiferroicity and Giant Switchable Anomalous Hall Conductivity in RuO2Zn2F2 Bilayer

Advanced Science, EarlyView.
Interlayer sliding in the RuO2Zn2F2 bilayer induces ferroelectricity and enables reversible valley polarization switching. The electric dipole and valley‐resolved band edges are intimately coupled, revealing sliding ferroelectricity as a powerful mechanism for electrical control of valley degrees of freedom in 2D materials.

Microstructure Optimization of Na3SbS4/Na3Zr2Si2PO12 Composite Solid Electrolytes for Improving Cycling Stability in All‐Solid‐State Sodium Batteries

Advanced Science, EarlyView.
This research demonstrates that incorporating 10 wt.% NASICON‐type Na3Zr2Si2PO12 into Na3SbS4 sulfide electrolytes mitigates interfacial instability and structural defects. The resulting composite enhances ionic conductivity to 3.97 * 10−4 S cm−1 and reduces activation energy.
