| Abstract Scope |
Biological materials exhibit unique structural, compositional, and crystallographic variabilities, which result in emergent mechanical properties and serve as a fascinating source of inspiration for the development of novel material designs. This study reveals the unique functional structural, composition and crystallographic heterogeneities of the Mg-calcite of the sea urchin endoskeleton (test). In this light, Micro-CT scan, Scanning Electron Microscopy, Energy Dispersive Spectroscopy, Transmission Electron Microscopy, Image Analysis, Nanoindentation and Finite Element Analysis were employed to analyse the ultrastructure in of the Paracentrotus lividus test and understand their function in relation to regional micromechanical needs. The results provide significant insights into the mechanical design of the echinoid skeleton and suggest promising biomimetic applications for the development of high-performance structured materials. |
