1. Crystal-structure determination from powder-diffraction data; Implementation and application of the newest methods in this field.
2. Application of powder diffraction methods in materials science, pharmacology, medicine, food sciences and investigations of art objects.
3. Qualitative and quantitative analysis of materials:
   • Synthesis and characterisation of polymolybdates, peroxopolymolybdates, peroxopolyvanadates and similar compounds.
   • Structural investigations of Schiff base - metal complexes.
   • Structural investigations of proton sponge (DMAN)- acid complexes.

achievments

• Successful crystal structure solution of Aza- and imine- analogs of 8-styrylxanthine the compounds which are of interest in pharmacology.
• Application of pseudo-atom method in the investigation of proton sponge (DMAN) and nitrosphenol complex.
• Application of PATSEE program to structural investigations in powder diffractometry.
• Successful crystal structure solution of vanadium and 2-hydroxy-3-methyl-2- cyclopenten-1-one complex as well as the complex of famotidine and Ni, with the use of laboratory X-ray data.
• Successful crystal structure solution of numerous structures (25-30 atoms in the asymmetric unit) on the basis of polycrystalline measurements (synchrotron and x-ray laboratory data).
• Elaboration of POWDER DIFFRACTION DATA FOR PHASE CHARACTERIZATION for more than 250 compounds.
• Elaboration of PROSZKI system for powder diffraction data analysis.

We offer for scientists working in powder diffractometry and similar disciplines (for their university research) free versions of following programs and files which were created in our group:

• PROSZKI – a System of Programs for Powder Diffraction Data Analysis.
• PC version of professor Bearlocher's XRS-82 program for Rietveld refinement.
• XTRAC program (LeBail method).
• x-ray powder diffraction files for DMAN and HMO
