Dolbin Alexander Vitoldovich is head of the group for dilatometric studies at the Department for thermal properties of molecular crystals of B. I. Verkin Institute for Low Temperature Physics and Engineering, Ph.D. in Engineering, senior researcher. Born 1967. He is an author and co-author of over 20 scientific articles and inventions.

The dilatometric group has been engaged in studies at low temperatures since 1972. The group includes two Drs: Victor Gavrilko, Valentin Esel'son and the young researcher Nicolay Vinnikov. Till 2004 the group was headed by the Dr Anatolii N. Aleksandrovskii (Deceased).

The researchers possessing high qualifications and unique modern technical equipment have succeeded in solving a number of scientific problems of crystal lattice dynamics, nuclear spin conversion and rotational motion of molecules in the crystal lattice.

The dilatometric investigations are made using two low temperature high-sensitivity capacitance dilatometers capable of detecting an atomic-spacing change in the sample size. One of the dilatometers is used to investigate the thermal expansion of solid gases in the temperature range of their existence. The other is intended for thermal expansion of any solid samples of arbitrary shapes in the temperature interval 1.5 — 300 K.

The researchers of this group have studied the thermal expansion of solidified gases Ar, Kr, Ne, H2, HD, D2, CH4 CHD3, CD4, N2, CO2, CO, N2O, NH3, CCl4, CBr4, SF6 and some of their solid solutions. Also, the thermal expansion of fullerite, various structural materials and crystal for low temperature and space applications has been investigated. The negative thermal expansion and the phenomenon of the orientational polyamorphism of the fullerite C60 have been found out at temperatures of liquid helium at last years. Low temperature dilatometric investigations of the thermal expansion were performed for the first time on samples of pure and doped with various gases single-walled carbon nanotube bundles (SWNTs) in the direction perpendicular to the bundle axes. Most of the experimental results have been included into the handbooks and monographs published in the USSR, Ukraine and the USA.

The group maintains a continuous scientific information exchange with researchers in different countries. On cooperation bases with the Department of Experimental Physics Umeå University (Sweden), Australian Nuclear Science and Technology Organization (Australia), National Kharkov Physico-Technical Institute Scientific Center (Ukraine) complex investigations have been performed on fullerite C60 (pure and doped with various gases). Joint studies are also carried out with the Institute of Physics of Solids, Russian Academy of Sciences (Russia). A programme has been developed to investigate the physical properties of C60 jointly with the National Mirzo Ulugbek University of Uzbekistan. The investigations of the thermal properties of SWNTs have been performed with E. L. Andronikashvili Institute of Physics Georgian Academy of Sciences, Tbilisi (Georgia).
