The laboratory carries out research aimed at studying the reactivity of solids of different classes: ionic compounds, molecular crystals as well as supramolecular systems, in order to create new materials: ionic electrolytes, oxygen membranes and dosage forms with improved properties.

Our areas of research are:

  •  study of the effect of hydrostatic pressure and low temperatures in molecular crystals;
  •  modification of drugs properties with the help of nanotechnologies;
  •  extraction of biologically active substances from plant, using mechanochemical methods;
  •  study of the transport properties of monophase and composite solid electrolytes;
  •  development of new methods and approaches to study oxygen exchange in non-stoichiometric oxides with mixed (oxygen and electronic) conductivity;
  •  mechanochemical stimulation of solid-phase synthesis for various practical applications.
We achieved the following original results:

  •  in the field of study of molecular crystals, including with variation of temperature and pressure: new data were obtained on polymorphism of drugs (tolbutamide, metacetamol, tolazamide), on crystal structures of new salts of serine and methionine with inorganic phosphorus and organic aromatic carboxylic acids, and on the effect of high pressures in bis(DL-serinium) oxalate dihydrate;
  •  using mechanical activation we obtained composites of betulin and its ethers presenting enhanced biological activity;
  •  we developed methods of synthesis and studied new inorganic materials, including composite proton electrolytes based on acid salts of alkali metals as well as carbon materials with addition of nanosized oxide particles, promising for electrochemical devices. We also developed membranes based on nanostructured perovskite-like oxides with mixed oxygen ion and electron conductivity.
