Magnetische Suszeptibilität der flüssigen B-Elemente

From experimental data of the magnetic susceptibilityχ for various B-elements (Tab. 2 and 3) the contributionχ _e from electrons of the outer shell has been derived. Theχ _e-values of theliquid B-elements are found to be distributed systematically in the periodic table (Tab. 4). Most of these values can readily be interpreted by simplified theories (Larmor-Langevin-term for non-metallic, Pauli-Landau-term offree electrons for metallic melts). Some complicated cases (e.g. liquid Te) can be explained by considering the chemical bond. Besidesχ _e, the temperature dependency of the susceptibility and its change by melting are discussed in detail (Tab. 6 and 7).     

Über die Gleichstromleitfähigkeit flüssiger Kohlenwasserstoffe

The steady-state current-voltage characteristic of the d.c. conductivity was measured for several liquid hydrocarbons, as well as its dependence on electrode spacing and — material. A hopping model is proposed in order to interpret the results. The temperature dependence of the conductivity of every hydrocarbon obeys the law

$$\sigma = \sigma _1 + \sigma _2 = \sigma _{01} \exp ( - E_1 /kT) + \sigma _{02} \exp ( - E_2 /kT)$$
