Prof., PhD, Head of laboratory

Link to:

Scientific interests:

Synthesis and
structural studies of inorganic materials and composites with interesting
optical, mechanical, electrical, magnetic, sensing and catalytic properties.

▪ Development of
non-classical methods for the production of materials with special interest in
the methods of soft chemistry, synthesis by solution combustion and
sonochemical synthesis.

▪ Detailed
structural and morphological characterization of materials with special
emphasis on X-ray diffraction methods, including qualitative and quantitative
phase analysis, analysis of diffraction line broadening (crystallite size and
micro-deformation) and refinement of crystal structures by the Rietveld method.
