    Notes: Nano-cell-elements of chalcogenide random access memory (C-RAM) based onGe2Sb2Te5 films have been successively fabricated by using the focused ion beammethod. The minimum contact size between the Ge2Sb2Te5 phase change film andbottom electrode film in the nano-cell-element is in diameter of 90nm. Thecurrent-voltage characteristics of the C-RAM cell element are studied using thehome-made current-voltage tester in our laboratory. The minimum SET current ofabout 0.3mA is obtained

    Notes: In order to study the strength and deformation properties of rock joint under differentshear velocities, normal stresses and undulation angles, series testes are conducted by a RMT-150Ctesting machines with artificial concrete rock joint samples in the present paper. Base on theexperimental results, it can be found that the peak shear strengths decrease with the increment ofshear velocity, and the decreasing rates tend to decrease with the increasing shear velocity. Theshear strength of rock joints increase with the increasing undulation angles, and linearly increasewith the increment of normal stress. It is also indicated that the shear stiffness increase with theincreasing normal stress, undulation angle as well as the shear velocity with a decreasing tendency

    Notes: This paper starts with a discussion on the theory of finite deformation and various typesstrain energy functions of rubber like material, the material parameter of elastic law of Gao[3] isestimated by experiment and numerical simulation. Because there are various types of strain energyfunctions, a user subroutine is programmed to implement the strain energy function of Gao[3] intothe program of MSC.Marc, which offers a convenient method to analyze the stress and strain ofrubber-like material with the strain energy function that is needed. Two examples will be presentedin this paper to demonstrate the use of the framework for rubber like materials. One is to simulate afoam tube in compression. The other one is to simulate a rectangle board with a circular hole. Afternumerical analysis, it is proved the numerical results based on Gao model are in perfect agreementwith the results based on Mooney model and the estimated material parameters are valid

    Surface enrichment effect on the morphological transitions induced by directional quenching for binary mixtures (2000)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 113 (2000), S. 719-727

    Notes: The morphological transitions during directional quenching-induced spinodal decomposition in binary mixtures are investigated by computer simulation. By setting the quenching front between the stable and unstable phases, and shifting the front with a constant velocity, the evolution of the domain morphologies is examined numerically on the basis of the time-dependent Ginzburg–Landau (TDGL) equation. Three different types of morphologies are found for the critical quenching. One is irregular morphology (IM), which is essentially equivalent to that produced by homogeneous quenching. The other two are regular, representing the characteristics of the directional quenching process. One is regular lamellar morphology (RLM) and the other is regular column morphology (RCM). By varying the shifting velocity of the cooling front, two morphological transition velocities, va from IM to RLM, and vi from RLM to RCM, are observed. In contrast to that, for the case of off-critical quenching, a new transition velocity vb from RCM back to RLM can be found if the cooling front is further shifted slower. This characteristic morphological transition is attributed to the surface enrichment effect appearing in the nonequal volume fraction system, which competes with linear instability triggered by initial thermal fluctuation in the early stage of spinodal decomposition. Detailed studies reveal that RLM can be easily formed and thus the region of RCM is reduced when the surface enrichment effect is stronger. On the other hand, RCM will be preferred if the initial thermal fluctuation is stronger. The quantitative relation between lamella width and shifting velocity of the cooling front is also presented. © 2000 American Institute of Physics.

    Crystallization and preliminary X-ray analyses of insect neurotoxins with analgesic effect from the scorpion Buthus martensii Karsch (2000)

    Notes: Three insect neurotoxins from the scorpion Buthus martensii Karsch, named BmK I1, BmK I4 and BmK I6, have been purified and crystallized. BmK I1 and BmK I4 show strong toxicity to insects, while BmK I6 is relatively weaker. They all exhibit an evident analgesic effect on mice; this is a novel biological function for scorpion insect toxins. Their crystals diffract to at least 3.5 (BmK I1), 2.8 (BmK I4), 2.8 (BmK I6 crystal form I) and 2.2 Å (of BmK I6 crystal form II) resolution on an ordinary X-ray source. Crystals of BmK I1 belong to space group P6, with unit-cell parameters a = b = 66.2, c = 176.7 Å. BmK I4 crystallized in the tetragonal space group I4, with unit-cell parameters a = b = 134.5, c = 60.6 Å. BmK I6 has been crystallized in two forms: form I belongs to space group C2, with unit-cell parameters a = 46.5, b = 85.2, c = 32.6 Å, β = 110.5°; form II belongs to space group R3, with the hexagonal unit-cell parameters a = b = 44.5, c = 164.7 Å.

    Electrical interaction energy between two charged entities (1999)

    Notes: A systematic approach is proposed for the derivation of the electrical interaction energy between two charged entities under a general surface condition. The analysis provides necessary information which facilitates the description of various phenomena of practical significance such as the adsorption of particles to surfaces, boundary effect on the electrophoretic behavior of a colloidal particle, and the behavior of a dispersed phase, e.g., its stability and phase transition. Four examples are provided to justify the applicability of the present method: a sphere and a planar surface, a sphere in a planar slit, a sphere in a spherical pore, and a sphere in a cylindrical pore. © 1999 American Institute of Physics.

    Nonisothermal dissolution and crystallization of ellipsoidal particles in liquid solutions (1995)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The kinetic behavior of both crystallization and dissolution of solid particles in liquid solutions is investigated. The effect of heat on the phenomena under consideration is taken into account. Although the present analysis is based on ellipsoidal particles, it can be extended to particles of various geometries by choosing an appropriate transformation. We show that the rate of dissolution increases with the decrease in particle size, and the greater the curvature of a surface, the faster the rate. On the other hand, the rate of growth of a crystal decreases with the increase of its size. For both dissolution and crystallization, the greater the curvature of a surface, the faster the rate of change in the particle size. In the analysis of the effect of the heat of dissolution/crystallization, we conclude that the rate of variation in the size of a particle for dissolution follows the order exothermic(approximately-greater-than)isothermal(approximately-greater-than)endothermic. No general rule is found for crystallization. The experimental data for the growth of ferrite allotriomorphs in Fe–C alloys reported in the literature is analyzed to justify the applicability of the present model. © 1995 American Institute of Physics.
