  • Dynamics of He atoms adsorbed on a carbon nanotube 
    Strzhemechny, M.A.; Legchenkova, I.V. (Физика низких температур, 2011)
    The spectrum of a helium atom adsorbed on an armchair single-walled carbon nanotube is calculated. It is shown that a helium adatom tunnels over the surface of the nanotube within a band 10 K (for ⁴He) to 14 K (for ³He) ...
  • Hysteretic phenomena in Xe-doped C₆₀ from x-ray diffraction 
    Prokhvatilov, A.I.; Galtsov, N.N.; Legchenkova, I.V.; Strzhemechny, M.A.; Cassidy, D.; Gadd, G.E.; Moricca, S.; Sundqvist, B.; Aksenova, N.A. (Физика низких температур, 2005)
    Polycrystalline fullerite С₆₀ intercalated with Xe atoms at 575 K and a pressure of 200 MPa was studied by powder x-ray diffraction. The integrated intensities of a few brighter reflections have been utilized to evaluate ...
  • Novel mechanism of the negative thermal expansion of doped fullerite C₆₀ 
    Strzhemechny, M.A.; Legchenkova, I.V. (Физика низких температур, 2010)
    A model for an atomic impurity in an octahedral void of fullerite C₆₀ is suggested. The problem is solved in the spherical oscillator approximation, which is appropriate for the larger rare gas atoms. It is shown that such ...
  • Process of intercalation of C₆₀ with molecular hydrogen from XRD data 
    Yagotintsev, K.A.; Stetsenko, Yu.E.; Legchenkova, I.V.; Prokhvatilov, A.I.; Strzhemechny, M.A.; Schafler, E.; Zehetbauer, M. (Физика низких температур, 2009)
    The process of normal hydrogen infusion into a C₆₀ powder at 1 bar and room temperature was monitored using x-ray diffraction. The effect of the intercalation on the lattice proved to be rather weak: the volume expansion ...
  • Structure and photoluminescence of helium-intercalated fullerite C₆₀ 
    Legchenkova, I.V.; Prokhvatilov, A.I.; Stetsenko, Yu.E.; Strzhemechny, M.A.; Yagotintsev, K.A.; Avdeenko, A.A.; Eremenko, V.V.; Zinoviev, P.V.; Zoryansky, V.N.; Silaeva, N.B.; Ruoff, R.S. (Физика низких температур, 2002)
    Intercalation of C₆₀ single crystals with helium was studied by powder x-ray diffractometry. It was established that the intercalation is a two-stage process, octahedral cavities are filled first and then tetrahedral ones, ...
  • The effect of the thermal reduction on the kinetics of low-temperature ⁴He sorption and the structural characteristics of graphene oxide 
    Dolbin, A.V.; Khlistuck, M.V.; Esel’son, V.B.; Gavrilko, V.G.; Vinnikov, N.A.; Basnukaeva, R.M.; Prokhvatilov, A.I.; Legchenkova, I.V.; Meleshko, V.V.; Maser, A.M.; Benito, W.K. (Физика низких температур, 2017)
    The kinetics of the sorption and the subsequent desorption of ⁴He by the starting graphite oxide (GtO) and the thermally reduced graphene oxide samples (TRGO, T reduction = 200, 300, 500, 700 and 900 °C) have been investigated ...
