In article number 1908218, Willem L. Noorduin and co‐workers present self‐assembled, microscopic BaCO₃/SiO₂ double helices, which integrate directional emission and enantiomorph‐specific circular retardance. This optical response emerges from the arrangement of nanoscopic mineral crystallites in the microscopic helix, and demonstrates how bottom‐up assembly can achieve ordering across multiple length scales to form complex functional materials [Image by Stefan Diller – Scientific Photography – Wuerzburg].

自组装微螺旋：自组装微螺旋的定向发射（Adv。Funct。Mater。26/2020）

Willem L. Noorduin和他的同事们在编号1908218中提出了自组装的微观BaCO ₃ / SiO ₂双螺旋，它们集成了定向发射和对映体特定的圆形延迟。这种光学响应来自微观螺旋结构中纳米矿物微晶的排列，并演示了自下而上的组装如何实现多种长度尺度上的有序排列，从而形成复杂的功能材料[Stefan Diller – Scientific Photography –维尔茨堡摄影]。
