Dr Maciej Zubko from the Institute of Materials Science and Engineering of the University of Silesia was selected, as the only Pole, as a member of the Commission on Electron Crystallography. The commission operates within the framework of the International Union of Crystallography (IUCr-International Union of Crystallography). 

Electron crystallography is a branch of science that studies the structure of materials using an electron beam. It is currently one of the most dynamically developed branches of crystallography. The applied research methods allow for imaging the structure of materials using electron microscopy and determining the crystal structure of objects by electron diffraction.

The International Union of Crystallography is an international organization which aims to standardize symbolism and nomenclature, promote crystallography, organize international congresses and conferences on crystallography.
