In biological architectures, material properties are optimized by the hierarchical structuring of components with a multiscaled order, from the nano‐ to the macroscales. Such designs enable, for instance, programmed yield points that maximize toughness. However, research efforts in biomimetic materials have focused on the assembly of nano‐ or macrostructures individually. In this study, high strength...
In article number 1808518, Blaise L. Tardy, Orlando J. Rojas, and co‐workers demonstrate the hierarchical assembly of chiral cellulose nanocrystals with controlled orientation of the helicoidal director. This is achieved using a complex topography, templating the construct. The obtained tiled architecture provides additional fracture propagation and energy dissipation mechanisms as well as a new means...
