TLDR
The fabrication of hollow ceramic scaffolds that mimic the length scales and hierarchy of biological materials are reported, suggesting that the hierarchical design principles offered by hard biological organisms can be applied to create damage-tolerant lightweight engineering materials.Abstract:
Creating lightweight, mechanically robust materials has long
been an engineering pursuit. Many siliceous skeleton species—
such as diatoms, sea sponges and radiolarians—have remarkably
high strengths when compared with man-made materials
of the same composition, yet are able to remain lightweight
and porous1–7. It has been suggested that these properties
arise from the hierarchical arrangement of different structural
elements at their relevant length scales8,9. Here, we report the
fabrication of hollow ceramic scaffolds that mimic the length
scales and hierarchy of biological materials. The constituent
solids attain tensile strengths of 1.75 GPa without failure
even after multiple deformation cycles, as revealed by in situ
nanomechanical experiments and finite-element analysis. We
discuss the high strength and lack of failure in terms of stress
concentrators at surface imperfections and of local stresses
within the microstructural landscape. Our findings suggest that
the hierarchical design principles offered by hard biological organisms
can be applied to create damage-tolerant lightweight
engineering materials.read more

TL;DR: Th thin, patterned layers with well-defined residual stresses influence the process of 2D to 3D geometric transformation and elucidate the ability of these stressed layers to alter the energy landscape associated with the transformation process and, specifically, the energy barriers that separate different stable modes in the final 3D configurations.
