Abstract:

After acquiring the nanoindenter Hysitron Triboindenter TI-950, we have been largely successful in obtaining high quality, high-resolution mechanical i.e., modulus and hardness maps of multiple biological composites. This includes the mechanical properties of the nacreous region from the California red abalone, the hard and luminescing shell Hinea brasiliana, in collaboration with Dr. Dimitri Deheyn, the ultrahard and abrasion resistant teeth from the giant mollusk, Cryptochiton stelleri, and the dactyl club from the stomatopod Odontodactylus scyllarus.
