Аннотация: Method of measuring the lifetime of the superheated liquid was used to determine temperatures of the limit superheating of the solution of oxygen-nitrogen-helium. The method of calculating the properties of this solution (temperature of limit superheating, saturated vapor pressure, and density) based on the data on the properties of solutions of oxygen-helium and nitrogen-helium was proposed. The surface tension of the solution of oxygen-nitrogen-helium was determined in a special experimen

Ключевые слова (''Своб.индексиров.''): amorphous ice --gas hydrates --carbon dioxide
Аннотация: Layers of amorphous ice saturated with methane, ethane, propane and carbon dioxide were obtained by condensation of molecular beams of rarefied vapor and gas on a substrate cooled with liquid nitrogen. The amorphous state of such objects at low temperatures is stabilized by the high viscosity and the small value of the stationary nucleation rate of the crystal phase. Their heating in condition of high metastability is accompanied by spontaneous explosive crystallization, which leads to the formation of gas hydrates. Glass-transition and crystallization temperatures were determined by changes in their dielectric properties under heating. An increase in the gas content in layers of amorphous ice causes an increase in the crystallization temperature without any significant changes in the glass transition temperature. At atmospheric pressure in a liquid n-pentane medium the retention of gas hydrates was observed up to temperatures close to 273. K. Self-preservation ensured the retention of hydrates in a metastable state at temperatures exceeding considerably their equilibrium dissociation temperatures. Samples of gas hydrates obtained at a maximum gas flow rate during the deposition contained up to 15 mass % of methane, 12 mass % of ethane, 13 mass % of propane, and 23 mass % of carbon dioxide

Ключевые слова (''Своб.индексиров.''): classical nucleation theory --method of lifetime measurement--ethane-nitrogen solution
Аннотация: The method of lifetime measurement is used to investigate the kinetics of spontaneous boiling-up of ethane-nitrogen solutions. Superheating temperatures Tn of solutions have been determined in experiments at pressure p = 1.0, 1.6 MPa and nitrogen concentration in ethane x = 0.5, 1.5 mol% in the nucleation rate range J = 1 × 104-2 × 108 s-1 m-3. At J 3 × 106 s-1 m-3 one can observe a satisfactory agreement between experimental data and homogeneous nucleation theory with respect to the temperature dependence of the nucleation rate and a systematic disagreement in the superheating temperature. At x = 0.5 mol% attainable superheating temperatures achieved by experiment coincide within the experimental error with theoretical values, and at x = 1.5 mol% exceed them by approximately 1.7 K. It is shown that one possible reason of such "excess superheating" of a solution beyond the theoretical value of Tn may be the absence of adsorption equilibrium at the critical bubble-ambient solution interface

Ключевые слова (''Своб.индексиров.''): nucleation --method of continuous pressure lowering--heterogeneous nucleation --superheating
Аннотация: The method of continuous pressure decrease has been used to investigate limiting (attainable) stretches of ethane–nitrogen solutions. Experiments were conducted at temperatures of 260, 266, 270, and 276 K and at nitrogen concentrations in the solution of 0.5 and 1.5 mol%. Pressure decrease rates were taken in the range 0.01–0.1 MPa/s. Distribution functions of liquid boiling-up events in dependence on pressure have been obtained allowing one to determine the most probable (attainable) pressures of liquid boiling-up and the nucleation rate. The results are interpreted in terms of nucleation thermodynamics and kinetics in liquids on a solid surface containing inclusions that initiate the boiling-up processes. It is shown that for realizing homogeneous nucleation it is not necessarily required that the wettability is close to the ideal one. The reasons for the discrepancy between experimental data and predictions of homogeneous nucleation theory at nucleation rates J 3 × 106 s−1 m−3 are discussed.

Ключевые слова (''Своб.индексиров.''): glass-transition --amorphous solids--aqueous-solutions
Аннотация: Low-temperature crystallization of amorphous materials has been analyzed theoretically taking into account nonstationary nucleation. The kinetics of crystallization of amorphous water layers, formed by depositing molecular beams on a substrate cooled by liquid nitrogen, has been investigated by differential thermal analysis. The conditions of gas hydrate formation in low-temperature amorphous-ice layers saturated with carbon dioxide have been studied. The glass-transition and crystallization temperatures of the gas hydrates have been determined from the change in dielectric properties upon heating. Under the deep-metastability conditions, crystallization of water-gas layers leads to the formation of crystallohydrates. Gas molecules are captured by the avalanche-like nucleation of crystallization centers and, therefore, are not displaced by the moving crystal-melt interface. Gas-hydrate samples formed in nonequilibrium water-gas layers are convenient for studying their thermophysical properties

Ключевые слова (''Своб.индексиров.''): 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
