Abstract The paper presents results of investigation on synthesis and characterization of cerium-dysprosium oxide. The input powders - dysprosium oxide Dy2O3 and cerium oxide CeO2 - were mixed so as to obtain equimolar ratio of cations, milled in alcohol and synthesized via solid state reaction process at 1350°C under 15MPa in vacuum for 2h. The microstructure, phase composition and thermal properties were analyzed. The obtained material was multiphase. Non-stoichiometric compounds were identified. Thermal diffusivity of investigated material decreased in the temperature range of 25-1000°C from 0,71 to 0,45 mm2/s.

Synthesis and characterization of a novel hexabenzocoronene (HBC) derivative attached with four alkyl swallow-tailed chains and two sulfur-containing chains are described. The designed peripheral decoration with dove tails as solubilizer and sulfur-containing groups as functionalizer is expected to improve the solubility of molecules, change the columnar spacing stacks and make for its orientation on matrix surface. Its UV−vis absorption spectra appeared in 350-400 nm region as same as typical that of this kind of compounds. The thermal properties as discotic liquid crystal and its orientation on matrix are being studied.
