Analysis of nano-structures in soft materials by electron tomography

研究の背景 Background


For better understanding of various properties, e.g., mechanical, electrical, transport properties, in soft materials, detailed characterization of their morphologies in three-dimension (3D) is essential. We have developed electron tomography, a microscopic method to image nano-scale structures in 3D, and applied them to various self-assembling structures in soft materials. We further improved electron tomography for meso-scale imaging technique because soft materials often exhibit hierarchical structures.

研究の目標 Outcome


In addition to the 3D imaging capability of electron tomography, another “dimension”, e.g., time, temperature, wet environment etc., will be incorporated to observe 3D structures in various environmental and dynamical processes in soft materials.
