DOI: 10.1002/adma.202211175
Abstract: Biological materials relied on multiple synergistic structural design elements typically exhibit excellent comprehensive mechanical properties. Hierarchical incorporation of different biostructural elements into a single artificial material is a promising approach to enhance mechanical properties, but… read more here.

DOI: 10.1016/j.ijsolstr.2018.06.004
Abstract: Abstract The Bouligand structure in some arthropods is a hierarchical composite comprised of a helicoidal arrangement of strong fibers in a weak matrix. In this study, we focus on the Bouligand structure present in the… read more here.

DOI: 10.1021/acs.biomac.3c00419
Abstract: Chitin can self-assemble into a liquid crystal phase with supramolecular chirality and Bouligand structure, which is widely found in the exoskeletons of arthropods. However, bionically replicating this structure via the self-assembly of chitin whiskers (CHWs)… read more here.
