Read moreThe Chinese puzzle ball is an ornate decorative artwork consisting of several concentric shells that move independently of each other. In the past decade, scientists provided a universal method for the fabrication of a conceptually similar micronanoscale structure, called the hollow multishell structure. New work proposes a novel concept of temporal-spatial ordering and dynamic smart behavior in these structures.
