B.I. Verkin Institute for Low Temperature Physics and Engineering of the NAS of Ukraine

Department of thermal properties and structure of solids and nanosystems

Head of the department: Doctor of Science, Professor Alexander Vitoldovich DOLBIN

The department was reorganized in 2018 by incorporation of two departments: Thermal properties of molecular crystals and Department of Structural studies of solids at low temperatures.

Department (laboratory) of thermal properties of molecular crystals was founded in 1962. Department was headed by Academician of NAS of Ukraine Manzhelii V.G. (1933-2013) from 1970 to 2007. From 2007 to 2016, the Department was headed by Doctor of Science Konstantinov V.A.

The main directions of the scientific activity of the Department:

Studied properties: heat capacity, heat of phase transitions, thermal expansion, compressibility, isochoric and isobaric thermal conductivity, dielectric penetration, conversion, quantum diffusion (configuration relaxation), sorption and thermally stimulated desorption.

Investigations carried out in the temperature interval from 0.4 to 300 K and pressures up to 8000 atm.

Experimental-methodical capabilities of the department:

There are a lot of experimental equipment in the Department:

  • helium cryostat for X-ray diffraction studies of powder samples with an operating temperature range from 2 K to room temperature;
  • helium cryostat for electron diffraction studies with an operating temperature range from 2 K to room temperature;
  • set-up for investigating the spectral-luminescent properties of objects with a small quantum emission of luminescence in a wide temperature range (10-300 K);
  • set-up for measuring the integral and time-resolved luminescence spectra and the relative quantum yield of molecular emission.
  • Some principal results obtained in the department:

    - detection of quantum diffusion in solid deuterium,

    - detection of a strong decreasing in helium transfer by a superfluid film on the surface of solid para-hydrogen

    - detection of glass-like behavior of weak solutions of cryocrystals,

    - detection of new mechanisms of strong influence of impurities on the thermal properties of crystals at low temperatures,

    - detection of negative thermal expansion of fullerite C60 at helium temperatures,

    - detection of the spin-nuclear conversion of deuteromethane in a solid solution of CD4-Kr at helium temperatures,

    - detection of the existence and mutual conversion of different orientation glasses in fullerite C60 doped with gases,

    - detection of the glass-like behavior of the thermal conductivity of clathrate gas hydrates in a wide temperature range (2–200 K);

    - detection of quantum diffusion of He, H2, Ne impurities in fullerite C60 at low temperatures (T <80 K);

    - it was first measured the coefficient of radial thermal expansion of nanotubes and the processes of spatial redistribution of impurity particles on the surface and inside the nanotube bundles were studied.;

    - it was first experimentally investigated the heat capacity of one-dimensional (1D) atomic chains obtained by adsorption of gases in the grooves of carbon nanotube bundles

    - it was obtained priority results of plastic characteristics of many cryocrystals, including a quantum hydrogen crystal and solid nitrogen;

    - it was obtained the proof of spontaneous phase separation in precipitated solid mixtures of hydrogen and deuterium

    - joint structural and luminescent research of fullerite saturated with gases were performed, which made it possible not only to detect a strong effect of the displacement of the point of orientational vitrification of Tg, but also to explain the nature of the sharp change in the integrated luminescence intensity during the passage of the Tg point;

    - X-ray and electron diffraction studies of the structure of various cryoalloy systems, incl. solid mixtures of the simplest molecular components with inert gases to study them as molecular glasses;

    - it was explained anomalous (106 times) acceleration of conversion in solid hydrogen at very high pressures

    - two polymorphs of para- bromobenzophenone crystals were obtained and a comparative study of the dynamics of triplet excitons in them was carried out.
