Ab Initio Study on 3D Anisotropic Ferroelectric Switching Mechanism and Coercive Field in HfO2 and ZrO2
Advanced Functional Materials, EarlyView.This study uncovers a new switching mechanism in HfO2 and ZrO2, where the absence of a non‐polar layer along the a‐direction induces interaction between polar layers. Consequently, the switching barriers for growth are lower than those for nucleation in this direction, leading to a size‐dependent coercive field that matches experimental observations ...Kun Hee Ye, Taeyoung Jeong, Seungjae Yoon, Dohyun Kim, Yunjae Kim, Cheol Seong Hwang, Jung‐Hae Choi +6 morewiley +1 more sourceLocal genetic adaptation to habitat in wild chimpanzees.

Advanced Functional Materials, EarlyView.This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.Laura Spies, Marcos Eduardo G.
