Cover Feature: A Self-Growing Strategy for Large-Scale Crystal Assembly Tubes (Chem. Asian J. 7/2018)

A self-growing strategy to prepare large-scale crystal assembly tubes is reported. Addition of a template and the need for sophisticated equipment can be avoided. The sidewall of the tubes is composed of a layer of polyhedral crystals that are connected together through grain coalescence. The formation mechanism of the assembled tubular structure is ascribed to a synergetic effect of the passivation layer and the dissolution–recrystallization process. This facile one-step strategy and the mechanism offer guidance for the fabrication of new superstructures.
