    Effect of Hydrostatic Pressure on the Electrical Conductivity of Ag2HgI4 and Cu2HgI4
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1974, 70 (07), 1974) Shibata, Shuichi; Hoshino, Hideoki; Shimoji, Mitsuo
    The electrical conductivity of the a and ft phases of Ag2HgI4 and Cu2HgI4 has been measured as a function of hydrostatic pressure up to 3xlO8Nm~2 in the temperature range between 283 and 363 K. The activation volumes determined from the data are temperature-dependent. The results are discussed on the basis of the continuum model for the atomic transport process.

    Lithium + Methylamine Solutions: Part 3.—Vapour Pressures
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1974, 70 (07), 1974) Nakamura, Yoshio; Horie, Yutaka; Shimoji, Mitsuo
    The vapour pressures of the lithium+methylamine system have been determined as a function of metal concentration between —55 and + 5°C. The activity of methylamine deviates positively from Raoult’s law at low metal concentrations and then negatively with increasing metal concentrations, in a similar way to that in metal + ammonia solutions. The results obtained are discussed using a simple model, in which solutions arc considered as consisting of metal atoms solvated by several methylamine molecules and free methylamine molecules.

    Lithium+Methylamine Solutions: Part 2.—Viscosities
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1972, 68 (1), 1972) Yamamoto, Mikio; Nakamura, Yoshio; Shimoji, Mitsuo
    The viscosities of solutions of Li and LiCl in methylamine have been measured with an Ubbelohde-type viscometer from –50 to –6.7°C as a function of concentration of the solutes. The observed viscosities increase with increase of solute concentration in both systems. These concentration dependences are discussed from the theoretical expression proposed previously on the basis of the kinetic theory of transport for liquids and liquid mixtures. The calculated viscosities are in qualitative agreement with the experimental data.
