Cover Picture: Harnessing Colloidal Crack Formation by Flow-Enabled Self-Assembly (Angew. Chem. Int. Ed. 16/2017)

Crack formation in a colloidal nanoparticle film can be harnessed by restricting the drying of the colloidal suspension using a flow-enabled self-assembly (FESA) strategy to yield large-area periodic cracks (i.e., microchannels) with tunable spacing. In their Communication on page 4554 ff., Z. Lin and co-workers also show that these uniform microchannels can be utilized as a template to guide the assembly of Au nanoparticles, forming intriguing nanoparticle threads.
