About us

The research group under leadership of Dr. Dejan Poleti has been created at the Department for General and Inorganic Chemistry at the Faculty of Technology and Metallurgy, University of Belgrade. The scientific research is carried out in several different fields: chemistry of coordination compounds and crystal engineering, solid state chemistry, materials science, many areas of crystallography (X-ray structural analysis of single crystals, polycrystalline, polymeric and nanomaterials).

History

The research at the Faculty of Technology and Metallurgy, University of Belgrade, in the field of crystallography has been started at the Department of Metallurgy by Dr. Mileva Rogulić followed by Dr. Jelica Mišović from the Department of Analytical Chemistry (1924 − 2010). The contribution to the development of crystallography in the filed of alloys and electron microscopy was given by Dr. Velimir Radmilović from the Department of Metallurgy. However, the main crystallographic center was formed under the direction of Dr. Dejan Poleti at the Department of General and Inorganic Chemistry. Dr. Dejan Poleti contributed also to the development of the Serbian Crystallographic Society as a vice president in the period from 1995 to 2004. His first collaborator Dr. Jelena Rogan, is the current secretary of the Serbian Crystallographic Society.

The research of the group, still led with great success by Dr. Dejan Poleti, is focused on the synthesis, characterization and X-ray structural analysis of transition metal complexes and organic-inorganic hybrids. The oxide systems of the spinel-type, doped bismuth oxides, and ferrites with nanoscale particles are also investigated. The nanomaterials for very different purposes based on the oxides of zinc, titanium, cerium, and some other metals are synthesized by mechanochemical and hydrothermal processes.
