的方解石棱柱的Pinna nobilis（Pinnidae，Linnaeus 1758）被证明是介晶材料的完美的例子。基于它们的超微结构和在棱柱形成的早期阶段出现的无定形瞬态前体，我们为濑户等人（2012）提出的介晶化途径提供了证据，其不是通过结晶纳米砖的自组织定向附着进行的，而是通过最初无定形纳米颗粒的聚集进行的，所述纳米颗粒随后通过外延成核转变为三-良好排列的纳米晶体的三维阵列。我们进一步了解了液体无定形碳酸钙在生物矿化过程中的作用，并提供了强有力的证据，在棱镜形成过程中发生的PILP样中间体。我们开发了一个新的方案的棱镜形成的基础上提出的研究结果提出的研究结果，并讨论了在体内的投机液体无定形碳酸钙（LACC）中间体的影响。
The calcitic prisms of Pinna nobilis (Pinnidae, Linnaeus 1758) are shown to be perfect examples of a mesocrystalline material. Based on their ultrastructure and on the occurrence of an amorphous transient precursor during the early stages of prism formation, we provide evidence for the pathway of mesocrystallisation proposed by Seto et al. (2012), which proceeds not by self-organized oriented attachment of crystalline nano-bricks but by aggregation of initially amorphous nanogranules which later transform by epitaxial nucleation to a three-dimensional array of well aligned nanocrystals. We further fathom the role of a liquid amorphous calcium carbonate in biomineralisation processes and provide strong evidence for the occurrence of PILP-like intermediates during prism formation. We develop a new scenario of prism formation based on the presented findings presented findings and discuss the implications of a speculative liquid amorphous calcium carbonate (LACC) intermediate in vivo.
