In article 1901300, Edwin Fohtung and co‐workers demonstrate an X‐ray Bragg coherent diffractive imaging technique to spatially resolve the evolution of nanoscopic ferroelastic needle‐like domains in individual BaTiO3 nanocrystals under external pressure. This provides a new paradigm for domain‐boundary engineering and potential for nanoscale functional devices aided by pressure‐induce structural phase transitions and ferroelectric phase transformation.

X射线衍射成像：单个铁电纳米粒子中的类似针的铁弹性域（Adv。Electron。Mater。5/2020）

在文章1901300中，Edwin Fohtung及其同事演示了X射线布拉格相干衍射成像技术，可在空间上解析外部压力下单个BaTiO3纳米晶体中纳米铁弹性针状畴的演化。这通过压力诱导结构相变和铁电相变，为域边界工程和纳米功能器件的潜力提供了新的范例。
