Crack engineering for the construction of arbitrary hierarchical architectures, Li, Yu, etc., Wang, Ren, PNAS, 2019
Novelty/impact/significance:
A conventionally detrimental phenomenon, cracking (leads to material failure), is used as a beneficial aspect to develop a powerful replication technique (two curing stages for the elastomer mold) to construct bioinspired complex hierarchical structures for interesting functions and properties, ingenious and effective.
