Other activities

All persons of our X-ray laboratory are members of the Czech and Slovak Crystallographic Association (CSCA). R. Kuzel is a secretary of the CSCA. The Association organizes conferences, seminars, schools and other activities in the field of X-ray and neutron diffraction in Czech and Slovak Republics. V. Valvoda is a member of the Regional Committee of International Union of Crystallography. The group took part in organization of the following conferences and seminars : X-ray meetings of the CSCA:
  • Annual Meeting of CSCA - Colloquium „Methods for study of crystal and real structures of materials", Bila, June 24- 28.

  • 232nd meeting - Use of synchrotron radiation sources
