Abstract

The diatom shell is an example of complex siliceous structure which is a suitable model to demonstrate the process of digging into the third dimension using modern visualization techniques. This paper demonstrates importance of a comprehensive multi-length scale approach to the bio-structures/materials with the usage of state-of-the-art imaging techniques. Imaging of diatoms applying visible light, electron and X-ray microscopy provide a deeper insight into the morphology of their frustules.

摘要

硅藻壳是复杂的硅质结构的一个例子,它是一个合适的模型,可以用现代可视化技术来演示向三维空间挖掘的过程。本文展示了使用最先进的成像技术,对生物结构/材料进行全面的多尺度方法的重要性。应用可见光、电子和 X 射线显微镜对硅藻进行成像,使我们能够更深入地了解它们的外壳形态。
