Journal ArticleDOI
Structure-property relationships of a biological mesocrystal in the adult sea urchin spine
Jong Seto,Yurong Ma,Sean A. Davis,Fiona C. Meldrum,Aurélien Gourrier,Yi-Yeoun Kim,Uwe Schilde,Michael Sztucki,Manfred Burghammer,Sergey Maltsev,Christian Jäger,Helmut Cölfen +11 more
TL;DR: A comprehensive analysis of an adult sea urchin spine is presented, and in revealing a complex, hierarchical structure, it is shown how Nature fabricates a material which diffracts as a single crystal of calcite and yet fractures as a glassy material.
Journal ArticleDOI
An artificial biomineral formed by incorporation of copolymer micelles in calcite crystals
Yi-Yeoun Kim,Kathirvel Ganesan,Pengcheng Yang,Alexander N. Kulak,Shirly Borukhin,Sasha Pechook,Luis Ribeiro,Roland Kröger,Stephen J. Eichhorn,Stephen J. Eichhorn,Steven P. Armes,Boaz Pokroy,Fiona C. Meldrum +12 more
TL;DR: This system provides a unique model for understanding biomineral formation, giving insight into both the mechanism of occlusion of biomacromolecules within single crystals, and the relationship between the macroscopic mechanical properties of a crystal and its microscopic structure.
Journal ArticleDOI
Dehydration and crystallization of amorphous calcium carbonate in solution and in air
Johannes Ihli,Wai Ching Wong,Elizabeth H. Noel,Yi-Yeoun Kim,Alexander N. Kulak,Hugo K. Christenson,Melinda J. Duer,Fiona C. Meldrum +7 more
TL;DR: It is shown that amorphous calcium carbonate can dehydrate before crystallizing, both in solution and in air, while thermal analyses and solid-state nuclear magnetic resonance measurements reveal that its water is present in distinct environments.
Journal ArticleDOI
A new precipitation pathway for calcium sulfate dihydrate (gypsum) via amorphous and hemihydrate intermediates.
TL;DR: This work investigates the early stages of precipitation of calcium sulfate from aqueous solution at room temperature and shows for the first time that amorphous calcium sulphate (ACS) and calcium sulfates hemihydrate are sequentially precipitated prior to calcium sulfite dihydrate (gypsum).
Journal ArticleDOI
A critical analysis of calcium carbonate mesocrystals
Yi-Yeoun Kim,Anna S. Schenk,Johannes Ihli,Alexander N. Kulak,Nicola B. J. Hetherington,Chiu C. Tang,Wolfgang W. Schmahl,Erika Griesshaber,Geoffrey Hyett,Fiona C. Meldrum +9 more
TL;DR: It is demonstrated that the data commonly used to assign mesocrystal structure may be frequently misinterpreted, and that these calcite/polymer crystals do not have nanoparticle substructures.
