Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Self-Reported Visual Function Index (VF-14) and Its Correlation with Best Corrected Visual Acuity in Elderly

Jurnal Sains Kesihatan Malaysia, 2017
This study was conducted to determine the score of self-reported visual function index (VF-14) and its correlation with best corrected visual acuity (BCVA) in the elderly population. Participants were elderly aged 60 years and above recruited from the on-going population-based longitudinal study on neuroprotective model for healthy longevity (TUA ...

Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

Advanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.
