Аннотация: The phenomenon of spontaneous bubble nucleation in extremely supersaturated (superheated) polymer–solvent systems has been studied experimentally. Spontaneous boiling-up temperatures T* for polystyrene and poly(ethylene glycol) solutions in a number of solvents have been measured at different values of pressure p and weight fraction of polymer c by the pulse heating method. The heating rate Ṫ varied from 105 to 107 K/s. For all systems studied, the values of T* have been found to increase with increasing p and c. The T*(p, c) dependence is discussed with the use of the data on the degree of compatibility of components. The peculiarities of polymeric solutions manifest themselves in the region c → 1, as follows: (i) an abrupt increase (by 1–2 orders of magnitude) in the slope of the T*(c) dependence, and (ii) the appearance of the dependence of T* values on the heating rate. Our approach to the interpretation of this result assumes a change in the initial composition of a solution in the course of heating due to polymer decomposition. An example of the extended phase diagram of a polymer–solvent system including the kinetic surface of T*(p, c) is given

WATER CLUSTERS
Аннотация: The stability of water clusters containing nitrogen oxide molecules is studied by the molecular dynamics method. The composition and size of thermodynamically stable heteroclusters are determined. The inclusion of two molecules of nitrogen oxide into aggregates containing seven or more water molecule increases the cluster stability. The correlation between the stability of heteroclusters and the ratio of self-diffusion coefficients of molecules of different kinds is observed. The real part of the cluster permittivity is maximal in the vicinity of the frequency of 200 cm–1. The inclusion of nitrogen oxide molecules into water clusters increases the characteristic frequency of dielectric relaxation. In general, heteroclusters are more stable with respect to perturbations caused by an external electric field than pure clusters with the same number of water molecules. The clusterization of water vapors accompanied by absorption of polar molecules of impurity favors a decrease in the greenhouse effect.

CRYSTAL LENNARD-JONES -- ASPECT STATIC -- CRYSTAL TWO-DIMENSIONAL -- DEPENDENCE OF TEMPERATURE -- ISOTHERMS
Аннотация: The molecular dynamic method is employed to study the thermodynamic perameters of a two-dimensional Lennard-Jones crysyal at negative pressures. The calculations are performed for five isotherms. The lowest temperature approaches absolute zero, and the highest temperature is 35% lower that than of the triple point. The limits of attainable tension and the thermodynamic stability of the crystal as well as the lifetimes of the ultimately strained states and the relaxation times in a disordering in the crystal are estimated. The thermal characteristics of disordering in the crystalline state are revealed and investigated

HIGH-T C SUPERCONDUCTORS -- TRAPPED FLUX -- MAGNETIC RELAXATION
Аннотация: The creep of a magnetic flux trapped in a bulk high-temperature superconductor has been studied. It has been found that the magnetic relaxation is retarded when the superconductor is placed near a ferromagnet. The value of the retardation effect depends on the sequence of magnetization and the approach of the superconductor to a ferromagnet. The magnetic relaxation is fully suppressed when a superconducting sample first is magnetized and then is brought close to a ferromagnet. An interpretation of this effect has been discussed. Being magnetized, a ferromagnet produces its own magnetic field. While penetrating into a disk sample through its planes, the ferromagnet field induces screening currents, which circulate oppositely to the current that arises upon trapping of the magnetic flux. As a result, the stability of the magnetic structure is sharply improved since opposite driving forces can act on different sections of the vortices

Аннотация: It is found that magnetic relaxation is suppressed in a high-temperature superconductor when it approaches a ferromagnet. It is supposed that this phenomenon results from formation of a nonequilibrium magnetic structure, in which counter driving forces act in different regions

MOLECULAR-DYNAMICS SIMULATION -- LENNARD-JONES LIQUID -- LIQUID–CRYSTAL
Аннотация: Molecular-dynamics simulations have been employed to calculate the coefficients of shear and bulk viscosity of a Lennard-Jones liquid in the temperature range T∗ = 0.4–2.0 in stable and metastable states. Penetration into the region of superheated states, as distinct from supercooled ones, does not lead to any essential changes in the shear viscosity. The bulk viscosity increases at the approach to the lines of liquid–crystal and liquid–gas equilibrium and in the metastable states. The evolution of autocorrelation functions of the components of the pressure tensor and the characteristic times of the viscoelastic relaxation of both a superheated and supercooled liquids has been investigated

SUPERCONDUCTORS -- FLUX CREEP -- MAGNETIC LEVITATION
Аннотация: The effect of the magnetic flux creep on the levitation stability of high-temperature superconductors was studied. It was shown experimentally that under a unipolar magnetization the levitation force decreased at a logarithmic velocity characteristic of the creep process. If the current structure was bi- or multi-polar one, which was formed in a sample exposed to a reversing external magnetic field, the force remained unchanged during a certain period of time. The theory of relaxation of magnetization and force for a partial and full penetration of the critical state was considered. It was shown that relaxation decelerated sharply if the region with a current producing the main magnetization was far from the superconductor surface. A concept of an open and internal magnetic relaxation was introduced. The time of the internal relaxation for different reverse depths was estimated. The calculated values approached the experimental values of the levitation stabilization time

FLUCTUATION -- IRREGULAR HIGH-ENERGY -- 1 / F СПЕКТРЫ
Аннотация: Experimental investigation of fluctuation dynamics in critical and transitional modes of heat mass exchange shows existence of irregular high-energy pulsations with power spectrum inversely proportional to the frequency—so called 1/f spectrum. Such regimes are characterized by the fact that an essential part of the pulsations energy is connected with very slow processes and mean that large high-energy bursts are possible in the system. Another characteristic feature of such regimes is scale invariance of the fluctuations distribution function. According to the theory, the 1/f fluctuations can emerge in physical systems due to simultaneous phase transitions in presence of sufficiently intensive white noise. This paper is devoted to detailed investigation of relaxation processes at steadying of stationary stochastic process in non-equilibrium phase transitions in system of two nonlinear stochastic differential equation. Such an information reveals statistical patterns of particular large-scale low-frequency bursts. Discontinuous “forgetting” of the initial conditions takes place. It is shown by numerical methods that distributions of duration and maximal values of the low-frequency extreme bursts have the power-like form. Experimental investigation results of statistical characteristics of fluctuation processes at ultrasonic cavitation and flash boiling of overheated water jets are presented. Results of the experiments carried out fit conclusions of the theoretical model for interacting heterogeneous phase transitions
