Аннотация: Исследована кристаллизация переохлажденного жидкого натрия. Кристаллический фрагмент, содержащийся в исходной микрогетерогенной системе, строился в виде комбинации ОЦК- и ГЦК-решеток. Результатом кристаллизации системы с 43-атомным кристаллическим формированием была дефектная ОЦК-структура, в то время как наличие 80-атомного зародыша порождало образование поликристалла, один из блоков которого характеризовался ОЦК-, а другой ГЦК-упаковками. Границы блоков, вероятно, образованы краевыми дислокациями

HELIUM
Аннотация: The method of lifetime measurement has been used to investigate the nucleation of the vapor phase in a superheated liquid nitrogen–helium solution. Temperature dependences of the mean lifetime of a metastable solution have been obtained in experiments at pressures p = 0.5, 1.0 MPa and several values of the mixture concentration. The nucleation rate J has been calculated. It varied in experiments from 104 tо 108 s?1 m?3. The results of experiments are compared with homogeneous nucleation theory. The paper deals with the size effect on the surface tension of a nucleus and the work of its formation.

LIQUID
Аннотация: Molecular dynamics methods have been used to investigate the kinetics of the liquid-gas phase transition in a two-component Lennard-Jones system at negative pressures and elastic stretches of the liquid to values close to spinodal ones. The molecular dynamics system consists of 2048 interacting particles with parameters of the Lennard-Jones potential for argon and neon. Density dependences of pressure and internal energy have been calculated for stable and metastable states of the mixture at a temperature T*?0.7±0.01 and three values of the concentration. The location of mechanical and the diffusion spinodals has been determined. It has been established that a gas-saturated mixture retains its stability against finite variations of state variables up to stretches close to the values near the diffusion spinodal. The statistic laws of the process of destruction of the metastable state have been investigated. The lifetimes of the metastable phase have been determined. It is shown that owing to the small height of the potential barrier that separates the microheterogeneous from the homogeneous state a system of finite size has a possibility to make the reverse transition from the microheterogeneous into the homogeneous state. The lifetimes of the system in the microheterogeneous state, as well as the expectation times of the occurrence of a critical nucleus, are described by Poissonian distributions.

VAN-DER-WAALS CHAIN-MOLECULE FLUID
Аннотация: An extended version of the van der Waals capillarity theory describing the liguid-vapor interface in the temperature range from the triple to the critical point is suggested. A model functional of thermodynamic potential for a two-phase Lennard-Jones system taking into account the effect of the highest degree terms of gradient expansion has been constructed. The identity of the thermodynamic and the mechanical definition of Tolman’s length has been proved in the framework of the adopted form of functional. The properties of nuclei of the liquid and the vapor phase are described. The paper determines: the work of formation of a nucleus, density profiles, size dependences of the surface tension, and the parameter ? in the Gibbs-Tolman-Koenig-Buff equation.© 2004 American Institute of Physics.

Аннотация: Crystallization of supercooled liquid sodium containing a spheroidal bce nucleus was studied by molecular dynamics simulations. The degree of supercooling and the critical nucleus size are determined. After solidification, the system exhibits elasticity of shear. Nucleus growth is accompanied by self-sustained aperiodic temperature oscillations. The radial distribution function is computed and Voronoi polyhedra are constructed for the system immediately before and after the transition. It is shown by the projection method that the crystallized system contains structural defects and Features a long-range order

HOMOGENEOUS NUCLEATION -- OXYGEN -- KRYPTON
Аннотация: The nucleation of the vapor phase in superheated nitrogen-helium liquid solutions was studied by lifetime measurements. The temperature dependences of the mean lifetime of metastable solutions were obtained at p = 0.5 and 1.0 MPa and several concentrations. The nucleation rate J was found to vary from 10(4) to 10(8) s(-1) m(-3). The adsorption of the high-volatility component on the metastable liquid-critical bubble boundary was shown to play a determining role in decreasing the temperature of the attainable solution super-heating as the solution concentration increased. The experimental data were compared with homogeneous nucleation theory. Systematic discrepancies were obtained; these discrepancies were related to the influence of the size effect on the surface tension of a nucleus and the work of its formation

LIQUID -- SOLUTIONS -- INERTIAL FORCES
Аннотация: A theory of the spontaneous boiling-up of supersaturated liquid solutions, which allows for all major factors limiting growth of a nucleus, such as volatility of solution components, viscous and inertial forces, and diffusional supply of a substance to the bubble, is proposed. Two approaches to determining the work of critical nucleus formation, based on the Gibbs method of diving surfaces and the Van der Waals theory of capillarity, are reviewed. Experimental data on the kinetics of boiling-up of nitrogen-helium and oxygen-helium solutions are presented. The results of the experiments are compared to the theoretical approaches to the problem of nucleation in gassed liquids, developed by the authors

MOLECULAR-DYNAMICS SIMULATION -- LENNARD-JONES FLUID -- NUCLEUS-LIQUID INTERFACE
Аннотация: We present the results of molecular dynamics simulations of the crystal nucleation rate in a supercooled Lennard-Jones liquid. The nucleation rate as a function of the pressure has been calculated by the method of determining the expectation time for liquid crystallization at temperatures higher than that of the triple point (T∗ = 0.865), close to the temperature of the terminal critical point of the metastable extension of the melting curve (T∗ = 0.55) and below this temperature (T∗ = 0.4). In computer experiments the nucleation rate varied from 1032 to 1035 s−1 m−3. The dimensions of critical nuclei and the pressure inside them, the surface free energy at a critical crystal nucleus-liquid interface, the height of the nucleation barrier, and the Zeldovich factor have been determined from the results of molecular dynamics simulations and their comparison with classical homogeneous nucleation theory. It is shown that the surface free energy at a curved crystal-liquid interface, as distinct from a flat interface, has also been determined at temperatures lower than the temperature of the terminal critical point of the melting curve and is a monotonically increasing function of the temperature

BOILING-UP -- CRYOGENIC LIQUIDS -- KRAMERS-ZELDOVICH METHOD
Аннотация: The kinetics of spontaneous boiling-up of superheated binary solutions of cryogenic liquids is studied. Within the framework of the Kramers-Zeldovich method, an expression is obtained for the steady state rate of homogeneous nucleation in a solution that takes into account free-molecular and diffusion regimes of the substance supply to a growing bubble. Viscous and inertial forces are also taken into account in the study of the nucleus growth dynamics. The work of critical nucleus formation is determined within the framework of the Gibbs and van der Waals capillarity theories. The dependence of the surface tension of critical bubbles in the solution on their size is investigated. The temperature of attainable superheating and nucleation rates in superheated solutions of cryogenic liquids with complete or partial solubility of the components are determined by a method of lifetime measurement. The experiments were conducted in a wide range of pressures and solution concentrations. The measurement results are compared with the theory of homogeneous nucleation taking or not taking into account the size effect in nucleation. It has been found that, by taking into account the size dependence of the surface tension of a nucleus, better agreement between the theory and experiment is obtained. The boundary of essential instability of the solution, that is, the diffusion spinodal, is computed

HOMOGENEOUS NUCLEATION -- DORING−VOLMER−FRENKEL−ZELDOVICH−KAGAN THEORY -- TOLMAN LENGTH
Аннотация: An alternative theory of homogeneous nucleation based on the theorem on surges has been formulated. This theory gives a steeper temperature dependence of the homogeneous nucleation rate along isobars than that given by the classical Doring−Volmer−Frenkel−Zeldovich−Kagan theory. By the alternative theory, lines of attainable superheat lie much higher than classical ones and are close to the spinodal. Taking into account the dependence of the surface tension on r, i.e., the nucleus radius of curvature, assuming the power dependence of the Tolman length, δ = const/rn, from the theories for different liquids the boundary of attainable superheats moves toward lower temperatures

RANDOM SYSTEMS -- NUCLEATION -- FLUCTUATION
Аннотация: A nucleation theory has been advanced, in which a metastable system is considered as the sum of statistically independent subsystems. This theory provides a flexible scheme taking into account actually all initiating factors, including even a separate “weak” point in a system. In the case of a homogeneous nucleation, the difference between the classical and alternative approaches consists in the expression for the preexponential. Depending on the diameter of the critical nucleus, numerical estimates of this preexponential by the two theories differ by 0–4 orders of magnitude for a supersaturated steam and 1–5 orders of magnitude for a superheated liquid

LENNARD-JONES FLUID -- CRYSTAL NUCLEATION -- METASTABLE SYSTEMS
Аннотация: We present the results of molecular dynamics simulation of crystal nucleation in a supercooled Lennard–Jones liquid. Temperature and baric dependences of the nucleation rate, the Zeldovich factor, nucleus size diffusion coefficient, the radius, and the pressure in a critical crystal nucleus are defined in computer simulation. The data obtained have been used in the framework of classical nucleation theory to calculate the effective surface energy of crystal nuclei γe. It is shown that the value of γe at T = const exceeds the value of the interfacial free energy at a flat crystal–liquid interface γ∞ and γe < γ∞ at p = const.

Аннотация: Vapor bubble nucleation on a microrough surface wetted by a volatile, incompressible liquid has been analyzed. The work of formation of a critical nucleus in a surface cavity has been evaluated. Concave sites of a surface with negative curvature can decrease the height of the activation barrier for the formation of a critical nucleus. The average density of the nucleation sites has been evaluated for a surface whose (small) deviation from a plane is specified by a Gaussian random function
