Anomaly in the specific heat and the nature of the isotropic liquid-nematic liquid crystal phase transition: Anomaly in the specific heat and the nature of the isotropic liquid-nematic liquid crystal phase transition. Anisimov, M. A.; Garber, S. R.; Esipov, V. S.; Mamnitskii, V. M.; Ovodov, G. I.; Smolenko, L. A.; Sorkin, E. L. (Vses. Nauchno-Issled. Inst. Fiz.-Tekh. Radiotekh. Izmer., Kryukovo, USSR). Zh. Eksp. Teor. Fiz., 72(5), 1983-93 (Russian) 1977. CODEN: ZETFA7. DOCUMENT TYPE: Journal CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) Section cross-reference(s): 75 The temp. dependence of heat capacity of MBBA [26227-73-6] and BMAB [11106-54-0] was investigated near the isotropic liq.-liq. crystal phase transition. The phase transition possesses properties of transitions of both the 1st and 2nd kinds. The results of previous work are distorted by a smearing out of the specific heat .delta.-function which is characteristic of transitions of the 1st kind. The main cause of the diffuseness is the presence of nonequil. impurities. An anal. of the temp. dependence of the specific heat shows that the fluctuations of the order parameter are not small at the transition point and that the Landau expansion is insufficient for a quant. description of the pretransition phenomena.

Ionic polarization effect in liquid crystal systems: Ionic polarization effect in liquid crystal systems.

DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 75, 76 The polarization of SnO2 and Al electrodes in nematic p-butyl-N-(p-methoxybenzylidene)aniline [26227-73-6] and cholesteric substances(cholesteryl nonanoate [1182-66-7]) were detd. by measurement of the time and temp. dependence of the electrode potential and elec. current. The electrode potential was measured with the aid of an electrometer. The thermoelec. effect arising during the heating of the sample is discussed. Electroerosion of the electrodes is obsd. .
