In article number 1700159, Eugen Rabkin and co‐workers observe the self‐healing and shape memory effects in single crystalline faceted gold particles of sub‐micrometer dimensions. Particles indented with a sharp diamond tip restored their original asymmetric shape after annealing at 600 °C. Atomistic and mesoscopic models demonstrate how a combination of plastic deformation and diffusion, which are classical examples of irreversible processes, can lead to a reversible shape recovery of the deformed particles.

形状记忆：通过缺陷介导的扩散在金微粒中的自我修复和形状记忆效应（Adv。Sci。8/2017）

在文章1700159中，Eugen Rabkin及其同事观察了亚微米尺寸的单晶多面金颗粒中的自愈和形状记忆效应。在600°C退火后，带有尖锐金刚石尖端的锯齿状颗粒恢复了其原始的不对称形状。原子模型和介观模型表明，塑性变形和扩散的结合是不可逆过程的经典示例，它们如何导致变形颗粒的可逆形状恢复。
