自组装温度响应polymer膜介导的矿物固-固相变：方解石-羟基磷灰石
Morphology preserving solid-to-solid transformation of minerals mediated by a self-assembled temperature responsive polymer membrane: calcite to hydroxyapatite
摘要：
具有复杂形貌的纳米晶体的组装引起了极大的科学兴趣。控制这些自组装结构的形成已被证明是困难的。在这里，我们提出了一种新的转换反应，用于将矿物的单晶转换为具有较低溶解度的物质的纳米晶体的组装体，而不改变整体形态。本研究的重点是菱方体方解石晶体向羟基磷灰石纳米晶组装体的转化，以控制转化过程。这产生了HAP纳米颗粒的颗粒组装体，大体上保留了原始的菱形方解石形态。
英文摘要：
Assemblies of nanocrystals with complex morphologies have solicited great scientific interest. Controlling the formation of these self-assembled structures has proved difficult. Here we present a novel transformation reaction for transforming a single crystal of minerals into assemblies of nanocrystals of substances with lower solubility without changing the overall morphology. This study focusses on the transformation of rhombohedral calcite crystals to assemblies of hydroxyapatite nanocrystals to control the transformation process. This yielded particle assemblies of HAP nanoparticles grossly preserving the original rhombohedral calcite morphology.
