We here present a comprehensive analysis of an adult sea urchin spine, and in revealing a complex, hierarchical structure, show how Nature fabricates a material which diffracts as a single crystal of calcite and yet fractures as a glassy material. Each spine comprises a highly oriented array of Mg-calcite nanocrystals in which amorphous regions and macromolecules are embedded. It is postulated that this mesocrystalline structure forms via the crystallization of a dense array of amorphous calcium carbonate (ACC) precursor particles. A residual surface layer of ACC and/or macromolecules remains around the nanoparticle units which creates the mesocrystal structure and contributes to the conchoidal fracture behavior. Nature's demonstration of how crystallization of an amorphous precursor phase can create a crystalline material with remarkable properties therefore provides inspiration for a novel approach to the design and synthesis of synthetic composite materials.</dcterms:abstract> <dcterms:issued>2012-03-06</dcterms:issued> <dc:creator>Gourrier, Aurelien</dc:creator> <dc:contributor>Seto, Jong</dc:contributor> <dc:creator>Davis, Sean A.</dc:creator> <dc:creator>Sztucki, Michael</dc:creator> <dcterms:bibliographicCitation>Proceedings of the National Academy of Sciences of the United States of America : PNAS ; 109 (2012), 10. - S. 3699-3704</dcterms:bibliographicCitation> <dc:contributor>Schilde, Uwe</dc:contributor> <dc:contributor>Cölfen, Helmut</dc:contributor> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/22782"/> <dc:creator>Ma, Yurong</dc:creator> <dcterms:title>Structure-property relationships of a biological mesocrystal in the adult sea urchin spine</dcterms:title> <dc:creator>Burghammer, Manfred</dc:creator> <dc:creator>Schilde, Uwe</dc:creator> <dc:creator>Jäger, Christian</dc:creator> <dc:contributor>Meldrum, Fiona</dc:contributor> </rdf:Description> </rdf:RDF>
