Detailed EBSD Study of a Bivalve Shell
An in-depth look at the structures of a mussel shell, characterised using Symmetry. Both calcite and nanostructured aragonite nacre are measured with an unprecedented level of detail and speed.

基于光纤板耦合CMOS技术的最新一代EBSD探测器，灵敏度提升显著，使得EBSD分析生物材料变得更容易。许多生物材料，如贝壳结构，对电子束辐照非常敏感，结构易破坏，其小尺度的结构需要高分辨率的分析。高速、高分辨率的EBSD面分布图能够有效地表征这些复杂的结构，从而提高我们对其形成和物理特性的理解。EBSD已广泛地应用于生物材料，包括：
右图展示了在普通贻贝壳中，方解石（顶部）—文石（底部）界面的EBSD面分布图。方解石采用晶粒相对取向（GROD）着色方案，文石采用标准反极图着色方案。
