Academic interests

  • Inorganic chemistry and crystallography.
  • Metal oxides with fractional valences.
  • Less common combinations of properties: towards halfmetallic ferromagnet.
  • Relationship between structure and phase transitions into valence-controlled states: temperatures of valence mixing, of superconductivity.
  • Less common compositions: carbides-oxides as pseudonitrides, nitrides-fluorides as pseudooxides.
  • Oxide materials with less-common properties: high conductivity, photocatalysis.

Academic interests, methods

  • Syntheses of new compounds at less-common temperature- and redox conditions.
  • Precise valence control in solid oxides of transition metals.
  • Structure determination from synchrotron x-ray and neutron diffraction data.
  • Mössbauer spectroscopy of valence-, spin-, and coordination states (in collaboration).
  • Magnetic, electric and thermal properties of inorganic solids (in collaboration).
