| Density and Electrical Conductivity of Molten (2K, Fe)Cl 2 , (2K, Co)Cl 2 , and (2K, Ni)Cl 2 | | | | Abstract
| The density and electrical conductivity of molten (2 K, Fe) Cl 2 , (2 K, Co) Cl 2 and (2 K, Ni) Cl 2 have been investigated. The density was measured by the maximum bubble pressure and dylatometric methods, the electrical conductivity by an AC technique. The molar volume and equivalent conduc-tance were calculated. | | | |

| The Physical and Molecular Properties of New Low Melting Nematics with Negative Dielectric Anisotropy | | | | Abstract
| The paper presents some basic physical properties (static electric permittivities, refraction indices, density and viscosity) of 2-chloro-4-n'-alkylphenyl esters of 4-/r-alkylbicyclo[2,2,2] octane-1-carbox-ylic acids (n'=l, n = 5 and 7) which are, at room temperature, nematics with a negative dielectric an-isotropy. On the basis of temperature dependence of the principal static permittivities £ H (T) and e±(T) of the nematics, using the Maier-Meier equations, the angle between the dipole moment vector and the long axis of mesogenic molecules, the apparent molecular dipole moment square pl P[) {T), and the ne-matic order parameter S(T) were determined. | | | |

| Thermodynamic Measurements on Selected Liquid Crystals at Normal and Elevated Pressures | | | | Abstract
| Densities have been determined for two 5-n-alkyl-2-(4-isothiocyanatophenyl)-l,3-dioxanes (6DBT, 10DBT), 4-n-tetradecyl-4'-cyanobiphenyl (14CB), 4-n-octyl-4'-thiocyanatobiphenyl (8BT) and two laterally aryl-branched mesogens 4-cyanobenzyl 5-(4-n-octyloxybenzoyloxy)-2-undecyloxybenzoate (4CNOUB), 3-cyanobenzyl 2,5-bis(4-n-octyloxybenzoyloxy)benzoate (3CN-BOB). The densities have been measured in the isotropic, nematic (only 3CNBOB) and smectic phases with a vibrating tube densimeter. The densities decrease with increasing alkyl chain length within a homologous series. Furthermore the enthalpy changes accompanying the phase transitions have been determined by DSC. | | | |

| Silberhalogenid-Silberchalkogenidsysteme, II Dichten geschmolzener Silberhalogenid-Silberchalkogenidmischungen Silver Halide-Silver Chalcogenide Systems, II Densities of Liquid Silver Halide-Silver Chalcogenide Mixtures | | | | Abstract
| The densities of liquid mixtures in the systems AgCl-Ag2S, AgCl—Ag2Se, AgCl-Ag2Te, AgBr—Ag2Te, AgJ-Ag2Te and AgJ-Ag2S have been determined as a function of composition and temperature by a dilatometric method. The molvoluminaisotherms of the systems AgJ—Ag2S and AgJ-Ag2Te show negative deviations from ideality, the other systems behave ideally. | | | |
