Resumen
The experimental electron microscopy images corresponding to crystalline structures of zeolites, oxide catalysts and materials, are frequently affected by instrumental factors such as defocoussing, spherical aberration, etc. as well as by other intrinsic parameters like the simple thickness and orientation. Thus, use of a computing method is necessary in order to reproduce bidimensional images under parameters that are known which allows the correct interpretation of the structural details in the experimental images. A series of image simulations were made by means of multislice methods, corresponding to crystalline structures of zeolites and oxides type catalysts. Results are compared and discussed.
