  • Ternary and Multicomponent Complexes of Some Transition Elements – Synthesis, Characterization and Analytical Application
    Ternary and multicomponent complexes of some metal ions (vanadium(IV,V), molybdenum(VI), tungsten(VI), niobium(V), tantalum(V)) are obtained and studied from a point of view their analytical application.

  • Inorganic chemistry and materials
    The scientific field can be subdivided in the following groups: i) Thermodynamic optimization of phase diagrams; ii) Experimental studies of phase diagrams and thermochemical determinations; iii) synthetic inorganic chemistry – synthesis of new materials (e.g. lead-free solders). The THERMOCALC and BINGSS software packages can be used for the optimization of phase diagrams. X-ray, thermal analyses, scanning electron microscopy are used for the phase equilibria studies. Participation in joint European projects: COST 531 and COST 599 MP0602 HISOLD (Advanced Solder Materials for High-Temperature Application- their nature, design, process and control in a multiscale domain).

  • Methodology of Chemistry Education Increasing of the quality of modern Chemistry education and of the professional preparation of the students who are future Chemistry teachers
    The attention of the working group is focused on the development of approaches, methods, means, and organizational forms helping the forming and the development of skills specifically connected with Chemistry, of life-management skills, and skills of life-long learning in both school students and undergraduate students. Great attention is paid to the creation of textbooks and supplementary working materials for Chemistry education at secondary schools and also of materials used for the preparation of the future Chemistry teachers. There is certain scientific interest in the problems occurring during the education of adults from the disadvantaged groups of society who also have significant educational deficiencies.
