Brief description of the research topic:

Our research group:

  • develops new methods of quantum crystallography, in particular the refinement of the Hirshfeld atom method with respect to X-ray and electron data and validates the usefulness of these methods;
  • performs structural studies (and electron density studies) of crystals of organic, inorganic and macromolecular compounds;
  • we study pharmaceuticals and potential drug molecules as well as their interactions with proteins and their complexes with DNA;
  • we also use electron diffraction in structural studies of nanocrystals;
  • we study crystals of compounds of pharmaceutical importance, important biological or biochemical compounds, minerals and inorganic compounds, etc.;
  • we study the polymorphism of ice and hydrates and search for new polymorphic varieties of ice;
  • we study thermal movements of atoms and molecules, as well as crystallization processes;
  • we study the molecular and electronic structure of crystals under pressure and in variable temperature conditions;
  • we study the nature of phase transitions in crystals (especially in minerals) under high pressure and in variable temperature conditions;

We perform most of our research within the framework of the grants we have. We perform a lot of research in large centers of mammoth physics such as synchrotrons (ESRF, DESY, APS, Soleil, SLS, Diamond, Elettra, Spring8) and neutron centers (ISIS, ILL, ORNL). We also provide services in all of the above-mentioned areas of crystallographic research of small molecules and macromolecules, but also in the field of biochemical and biophysical research.
