Laboratory has obtained 6 patents of Russian Federation during last 6 years.  

Main results:

• Matrix isolation method has been developed and cryochemical reactions of atoms and clusters of magnesium and samarium with some small molecules were studied. The higher activity of metal clusters in comparison with their atoms was shown. Spectral data were confirmed by the results of quantum chemistry calculations.

• The methods of formation and stabilisation of metal nanoparticles of 5-10 nm in size have been developed using polyxylylene monomers polymerized at low temperatures and  acrylic monomers. The inclusion of silver nanoparticles, obtained by cryosynthesis and by chemical reduction in reversed micelles was made. 

• The cryoformation of silver and copper nanoparticles including in liquid crystalline matrix has been performed. It was shown the possibility of unusual chemical transformations of metal nanoparticles at low temperatures and of new sensor systems obtaining.

• The main problem for developing  investigations is the connection between the reactive specie size and their reactivity. The new research directions have been established during last 5 years– cryonanochemistry and metal  nanochemistry.
