Summary
The nanostructure of aerogels is most impressive. We present some microscopic pictures to illustrate the variety of structures observed in inorganic and organic aerogels. The pictures are accompanied with a brief discussion of the techniques used for imaging and gives several practical hints to achieve excellent pictures in transmission or scanning electron microscopy.
