    Chemical equilibrium in argon: Anomaly of density dependence of dimerization reaction in the medium density region (1989)

    Notes: We studied the dimerization equilibrium of 2-methyl-2-nitrosopropane in argon at 25.0 °C from about 500 to 1200 kg m−3. It is clarified that in the simplest solvent, argon, there exists a definite difference in the density dependence of the equilibrium constant between the high and medium density regions. In the high density region, the equilibrium constant shows a sizable increase with the solvent density as in the liquid phase. Near the critical density, however, the equilibrium constant shows little density dependence.

    Chemical reaction in medium density fluid. Solvent density effects on the dimerization equilibrium of 2-methyl-2-nitrosopropane in carbon dioxide (1989)

    Notes: The dimerization equilibrium of 2-methyl-2-nitrosopropane in carbon dioxide was studied in a wide range of solvent density from 200 to 1100 kg m−3 at 25.0 and 35.0 °C. We found an inversion of the density dependence of the equilibrium constant. The configurational volume change for the dimerization has a large positive value in the medium density region, although it is negative in the high density region as usually observed for the bond formation reactions in the liquid state. This anomaly is reproduced by the cavity distribution function calculated from the integral equation based on the HNC or PY approximation for the Lennard-Jones fluid model. The large positive value in the medium density region is interpreted in terms of desolvation effect due to the dimerization. The long-range correlation between molecules due to attractive forces is suggested to play an important role in determining the reaction volume in the medium density region.

    Irreversible behavior of the transport critical current in polycrystalline YBa2Cu3Oy (1989)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 55 (1989), S. 2342-2344

    Topics: Physics
    Notes: Temperature and magnetic field dependence of the critical current density Jc and magnetization of the polycrystalline high Tc oxide superconductor YBa2Cu3Oy have been measured. At low temperature, Jc shows a different temperature dependence between field cooling and zero-field cooling, that is, the Jc value measured when the sample was cooled in a fixed magnetic field was larger than that measured when the sample was cooled in zero magnetic field and then a magnetic field was applied. This irreversible behavior of Jc disappeared at a reduced temperature difference 1–t proportional to H2/3 (H is the magnetic field). Moreover, we have observed that the slope dV/dJ just above Jc began to increase rapidly with increasing temperature above 70 K. These experimental results can be attributed to the effects of grain boundaries.

    Investigation of the fabrication process of hot-worked stainless-steel and Mo sheathed PbMo6 S8 wires (1988)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Stainless-steel and Mo sheathed PbMo6 S8 wires have been fabricated by hot working from modified PbS, Mo, and MoS2 mixed powders which were prepared by reacting Pb, Mo, and S at 530 °C. Critical current densities were investigated for different preparation conditions, and it is revealed that obtaining continuous current path between PbMo6 S8 grains is the most important factor to achieve high critical current density. The Jc value of 2.8×104 A/cm2 (8 T), 7.8×103 A/cm2 (15 T), and 1.3×103 A/cm2 (23 T) was observed for the PbMo6 S7.0 wire heat treated at 700 °C.

    Compositional distribution in the cross section of chemical-vapor-deposited Nb3Ge tape conductors and its correlation with superconducting properties (1987)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Chemical-vapor-deposited Nb3Ge tapes 2.5 mm wide with Nb3Ge layer thickness of 5–60 μm were prepared under various processing conditions. Though the depth profile of the Nb concentration in the Nb3Ge tapes determined by x-ray microanalysis was fairly uniform, with a variation less than 4 at. % for many Nb3Ge tapes, the distribution of the Nb concentration over the whole cross section of the Nb3Ge layer varied considerably, with a variation of 10–18 at. % for various Nb3Ge tapes. In this distribution, Nb concentrations at the tape edges were found to be higher than those on its sides for all of the Nb3Ge tapes prepared. The origin of this singular distribution of the composition is discussed. The Tc values for narrower tapes cut out lengthwise from the 2.5-mm-wide tapes were measured resistively. They correlated closely with the compositional distribution in the cross section of the Nb3Ge tapes. The Tc values (midpoints) of Nb3Ge tapes incorporating compositions within the Nb concentration range of 70–75 at. % were found to be near or above 20 K.
