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.
