From Nature to Engineering: Bio-mimetic and Bio inspired Materials

There is a growing need for the development of new light-weight structural materials with high strength and durability that are low-cost and recyclable. Nature has evolved efficient strategies, exemplified in the crys-tallized tissues of numerous species, to synthesize materials that often exhibit exceptional mechanical prop-erties. These biological systems demonstrate the ability to control nano- and microstructural features that significantly improve the mechanical performance of otherwise brittle materials. In this work, we investi-gate a variety of organisms, specifically, the hyper-mineralized combative dactyl club of the stomatopods (Figure 1), a group of highly aggressive marine crustaceans[1], and the heavily crystallized radular teeth (Figure 2) of the chitons, a group of elongated mollusks that graze on hard substrates for algae[2,3]. In addi-tion, we will discuss developments in multifunctional biological structures. From the investigation of struc-ture-property relationships in these unique organisms using modern chemical, morphological, and mechani-cal characterization techniques, we are now developing and fabricating cost-effective and environmentally friendly engineering composites with impact resistance and synthesizing biologically inspired nanomaterials for energy conversion and storage.
