  • Advances in the study of gas hydrates by dielectric spectroscopy 
    Lunev I.; Kamaliev B.; Shtyrlin V.; Gusev Y.; Kiiamov A.; Zaripova Y.; Galiullin A.; Farhadian A.; Varfolomeev M.; Kelland M. (2021)
    The influence of kinetic hydrate inhibitors on the process of natural gas hydrate nucleation was studied using the method of dielectric spectroscopy. The processes of gas hydrate formation and decomposition were monitored ...
  • Dielectric response of hydrated water as a structural component of nanofibrillated cellulose (NFC) from different plant sources 
    Lunev I.; Greenbaum (Gutina) A.; Feldman Y.; Petrov V.; Kuznetsova N.; Averianova N.; Makshakova O.; Zuev Y. (2019)
    © 2019 The current work illuminates the interplay between nanofibrillated cellulose (NFC) films and hydrated water. The NFC films from three sources of technological importance, i.e. cotton, wood and flax, are compared. ...
  • Dynamic and structural properties of oxyethylated isononylphenols 
    Arkhipov V.; Bogdanova S.; Idiyatullin Z.; Lunev I.; Filippov A. (2016)
    © 2016Diffusion coefficients, dielectric relaxation times and refraction coefficients were measured, and activation energies of translational and rotational mobilities were determined for a series of oxyethylated phenols ...
  • Electrochemical Sensors for Vanadium Determination 
    Gogol E.; Denisov E.; Lunev I.; Egorova O.; Sharipova L.; Gusev Y. (2017)
    © Published under licence by IOP Publishing Ltd. This paper is dedicated to the problem of vanadium (V) determination by the means of voltammetry. The comparison of results obtained for two types of sensor: volume glassy-carbon ...
  • Photostimulated phenomena in relaxors 
    Mamin R.; Migachev S.; Sadykov M.; Lunev I.; Izotov V.; Gusev Y. (2003)
    The action of illumination on the conducting and dielectric properties of lead magnoniobate was investigated. The photostimulated currents were examined and the spectral dependence of photoconductivity in the region of ...
  • The effect of clay morphology on water relaxation 
    Lunev I.; Nigmatullin R.; Zavidonov A.; Gusev Y.; Manyurov I. (2001)
    The frequency dependence of the permittivity of water in calcium kaolinite (clay) is measured. It is shown that two mechanisms contribute to dipole relaxation of water. One refers to water in the free volume of pores in ...
  • The low-temperature dynamic crossover in the dielectric relaxation of ice I<inf>h</inf> 
    Popov I.; Lunev I.; Khamzin A.; Greenbaum A.; Gusev Y.; Feldman Y. (2017)
    © 2017 the Owner Societies. Based on the idea of defect migration as the principal mechanism in the dielectric relaxation of ice I h , the concept of low-temperature dynamic crossover was proposed. It is known that at high ...
