Framework determination of a polytype of zeolite beta by using electron crystallography

Fourier reconstruction is developed for high resolution transmission electron microscopy (HRTEM) images and enhancement of the atomic positions in blurred potential map obtained by the reconstruction with a support of Patterson map are presented. A Fourier reconstruction method for making a 3d-potential map for HRTEM images might be a more robust way to retrieve the crystal structure when several HRTEM images are taken with high resolution and correction is available.
