Structural Characterization of Meso-structured Materials.

二氧化硅介孔晶体具有有序的介孔结构，孔径为几个纳米。我们用电子显微镜研究了它们的结构，并发展了三维(3D)重建方法，如电子断层扫描。研究结果如下：(I)我们表征了球形二氧化硅介孔材料中的三维介孔网络，(Ii)我们在笼型二氧化硅介孔材料中观察到了新的四面体密排结构。

Silica mesoporous crystals have well-ordered meso-structures with the pore size of several nanometers. We have investigated their structures by electron microscopy and developed three dimensional (3D) reconstruction methods such as electron tomography. The results were as follows ; (i) we characterized 3D networks of mesopores in spherical silica mesoporous materials, (ii) we observed new tetrahedrally close-packed structures in cage-type silica mesoporous materials.
