Amorphous samples are obtained by molecular beam deposition under vacuum conditions on the substrate cooled with liquid nitrogen. The vitrification and crystallization temperatures are determined from the changes in the dielectric properties of the condensates upon heating. The kinetics of crystallization of amorphous water layers is studied by differential thermal analysis. The temperature conditions for the growth of thick methane crystalline hydrate layers during the low-temperature condensation of molecular water-gas mixture beams are found |

Рубрики: ФИЗИКА Кл.слова (ненормированные): NMR -- RELAXATION TIMES -- SOLID HELIUM Аннотация: The phase structure of the rapidly quenched solid helium samples is studied by the NMR technique in dilute 3He-4He mixtures at 1.35-1.8 K. The pulse NMR method is used to measure the spin-lattice and spin-spin relaxation times for all coexisting phases. An additional spin-lattice relaxation process is found just before vitrification of the liquid inclusions in hcp matrix. The relaxation rate of the new process coincides with that of bcc solid. It has been found that the new relaxation process is observed only in the temperature region of the phase diagram where an equilibrium bcc phase exists. After the liquid inclusions vitrification has been completed, the contribution from the bcc phase is not detected. The spin-lattice relaxation times in all of coexisting phases are discussed \\\\expert2\\nbo\\Journal of Low Temperature Physics\\2014, v.175, p. 154-159.pdf |

Рубрики: ФИЗИКА Кл.слова (ненормированные): AMORPHOUS ICE -- CRYSTALLIZATION -- VITRIFICATION Аннотация: Layers of ethane-saturated amorphous ice were prepared by depositing molecular beams of water and gas on a substrate cooled with liquid nitrogen. The heating of the layers was accompanied by vitrification (softening) followed by spontaneous crystallization. Crystallization of condensates under the conditions of deep metastability proceeded with gas hydrate formation. The vitrification and crystallization temperatures of the condensates were determined from the changes in their dielectric properties on heating. The thermal effects of transformations were recorded by differential thermal analysis. The crystallization of the amorphous water layers was studied by electron diffraction. Formation of a metastable packing with elements of a cubic diamond-like structure was noted \\\\expert2\\nbo\\Russian Journal of Physical Chemistry A, Focus on Chemistry\\2014, V.88, N 10, p.1706.pdf |
