    Some aspects of nonisothermal crystallization of polymers. III. Crystallization during melt spinning (1974)

    Notes: Crystallization during melt spinning is studied as an example of the nonisothermal crystallization of polymers. The following equation is derived, taking the temperature distribution within a filament into consideration: \documentclass{article}\pagestyle{empty}\begin{document}$$ \kappa \nabla ^2 T = {\rm V} \cdot {\rm grad } \ T - \frac{{\Delta H}}{{C_p }}{\rm V} \cdot {\rm grad } \ X $$\end{document} where T = temperature, X = crystallinity, κ = thermal diffusivity, V = velocity, ΔH = heat of crystallization, and Cp = specific heat at constant pressure. The assumptions and the procedure for a numerical calculation of crystallinity and temperature within a running filament are described, and some results of calculation are illustrated. The results are compared with those obtained by a simpler calculation in which the radial temperature distribution is neglected. The simpler method proved useful in connection with x-ray measurements.

    Some aspects of nonisothermal crystallization of polymers. I. Relationship between crystallization temperature, crystallinity, and cooling conditions (1972)

    Notes: The changes in temperature and crystallinity of polymer during nonisothermal crystallization were theoretically analyzed assuming a cooling condition under which heat transfer occurs at a rate proportional to the difference in temperature between polymer and the environment. When a plateau appears in the temperature change during crystallization, crystallization temperature can be predicted by a simple method. This method gives nearly the same value as that obtained by successive calculations of temperature and crystallinity throughout the whole process. In addition, a graphic method is presented to predict crystallization temperature. By using the plateau temperature observed in melt-spinning experiments, the crystallization rate under molecular orientation is evaluated. Furthermore, a method applicable to estimating the ultimate crystallinity is proposed. A rough estimation of the increase in the rate of crystallization under molecular orientation was carried out for very high-speed spinning of poly(ethylene terephthalate).

    Some aspects of nonisothermal crystallization of polymers. II. Consideration of the isokinetic condition (1973)

    Notes: In the previous paper a practical method has been applied for an analysis of non-isothermal crystallization in terms of data of isothermal crystallization. The fundamental equation was written on the assumption of the isokinetic conditions in the following form: \documentclass{article}\pagestyle{empty}\begin{document}$ X\left( {\rm t} \right) = 1 - \exp \left[ { - \left( {\int_0^t {K\left( T \right)d\tau } } \right)^n } \right] $\end{document} where X(t) is the degree of phase transformation at time t, and n is the Avrami index determined in the isothermal experiments; K(T) is connected with the crystallization rate constant of the isothermal crystallization, k(T), through the relation K(T) = k(T)1/n. The equation is derived on the basis of the well-known theory of phase transformation. Experiments of nonisothermal crystallization of high-density polyethylene were carried out under various cooling conditions. The change in crystallinity during the process was followed by using the above equation in the course of the primary crystallization. A procedure of the analysis of the whole, including both the primary and secondary processes, is suggested as an eminently practical one on a more general assumption.

    Electrogenesis in mouse neuroblastoma cells In vitro (1971)

    Notes: Intracellular microelectrode studies of passive membrane properties and action potential generation were carried out on cloned and uncloned mouse neuroblastoma cells in tissue culture. The cloned cells were studied between the eighth and tenth months and the uncloned cells between the third and fifth weeks after primary dissociation. Electrophysiologic measurements of cell membrane properties were made by passing stimulating current pulses across the cell membrane from an intracellular microelectrode and recording simultaneously from the same electrode, by means of a bridge circuit, the changes in membrane potential. The range of responses to electrical stimulation varied from passive increases in membrane potential to repetitive firing of action potentials. A 20 fold range in spike generating capability was found. Passive membrane properties (membrane potential, specific membrane resistivity, and specific membrane capacitance) were similar to those of sympathetic neurons in intact preparations. Seventy-nine percent of the cloned cell line compared to 94% of the uncloned line were capable of generating action potentials. Less than 2% of the cloned cells showed repetitive firing whereas 23% of the uncloned cells had this property. As in several types of normal neurons, the action potential mechanism was largely, although not completely, blocked by iontophoretic and bath applied tetrodotoxin.

    Responses of neuroblastoma cells to iontophoretically applied acetylcholine (1971)

    Notes: Dissociated mouse neuroblastoma cells were studied in vitro by using intracellular microelectrodes for electrical stimulation and recording. Some, but not all cells, which exhibited well developed action potentials to electrical stimulation also showed changes in membrane potential to iontophoretically applied acetylcholine (ACh). The types of responses to ACh varied. Short latency depolarizing responses to pulses of ACh (similar to those obtained with skeletal muscle) as well as sustained depolarization to steady ACh application (D response) occurred. A longer latency prolonged hyperpolarizing response (H response) and bi- and triphasic combinations of H and D responses were also seen.Pairs of cells showing morphologic contact were tested for the occurrence of effective synaptic coupling by placing intracellular microelectrodes in each cell. In none of 95 cases tested did spike activity produced by direct electrical stimulation of one cell elicit a synaptic potential of 200 μv or more in the other.
