RESEARCH ACTIVITIES

• Synthesis and characterization of different metal oxides. Special attention is focused on the mechanisms of the metal oxides formation, such as ZrO₂, HfO₂, SnO₂, TiO₂, WO₃, V₂O₅, Nb₂O₅, as well as metal oxides of platinum group.
• Investigation of the metal oxide nanostructured particles with possible applications in advanced technologies, as well as for biomedical applications.
• Development of new synthesis methods of ferrites and investigation of their chemical, physical and magnetic properties.
• Investigation of various host materials for the immobilization of radioactive wastes.
• Investigation of the doping mechanism and its effect to mullite when doped with some transition metals, the effect to SnO₂ when doped with Sb, and the effect to In₂O₃ when doped with Sn. Crystal structure of the doped powder samples will be solved by means of the Rietveld method. Thermal and electrical properties of the doped samples are correlated with the structure.
• Study of the influence of the chemical composition on basic processes of zeolite nucleation and crystal growth – "memory" effect of the gel.
• Zeolites syntheses from "clear" solutions via hydrothermal crystallization following the changes of structural, chemical and particulate properties.
• Thermal and mechanochemical transformations of zeolites in the solid state.
• Modeling of the fundamental processes of zeolite nucleation and crystal growth at molecular level and its experimental testing.
• Study of processes of heavy metal ions removal from solutions by ion-exchange on zeolites and their use in waste water treatment.
