Golev I. M. Thermoelectric Properties of Compacted Micro- and Nanodisperse Graphite Materials [Електронний ресурс] / I. M. Golev, V. N. Sanin // Журнал нано- та електронної фізики. - 2014. - Т. 6, № 3. - С. 03063-1-03063-2. - Режим доступу: http://nbuv.gov.ua/UJRN/jnef_2014_6_3_65 The experimental results of measuring the Seebeck coefficient S for carbon deposits containing multiwalled carbon nanotubes, compacted nanofibers, nano- and ultradisperse amorphous carbon are presented. The value of S for such kind of materials lies in the range of 7 to 60 <$Emu>V/K. It is indicated that a hopping conduction mechanism is typical of the compacted materials.

Golev I. M. Surface Activity of Graphite Nanomaterials [Електронний ресурс] / I. M. Golev, V. N. Sanin, E. A. Russkih, D. V. Russkih // Журнал нано- та електронної фізики. - 2015. - Т. 7, № 4. - С. 04015-1-04015-3. - Режим доступу: http://nbuv.gov.ua/UJRN/jnef_2015_7_4_17 Presents the results of experimental investigation of surface activity of carbon nanostructures: sensor films on the basis of amorphous nanodispersed carbon, carbon nanofibers and disrupted nanographite. The increase in the electrical resistance of such material at a concentration of vapors of acetone in air is 12000 ppm at room temperature in the order of 4 %. It is shown that the growth of the resistance associated with the change in the concentration of conduction electrons in the contacts between the structural elements of the films.
