As a result of our experiment the following outcomes are to be made: If c > 0.6 (x > 0.2) no spontaneous crystallization occurs and if c < 0.4 (x < 0.12) only the maximum of density is detected and for this concentration range crystalsization occurs always at temperatures higher than − 40°C. The replacement of 12 % water molecules by glycerol molecules seems sufficient for destroying the...
The conduction band energy Vo and the electron mobility u in n-, isobutane (n-C4, i-C4), n- and isopentane (n-C5, i-C5) fluids were measured as a function of density N in order to examine the effect of molecular structure on the electronic behaviour in nonpolar fluids. Vo values were determined by photoelectric work function measurements. u values were determined by a time-of-flight methods. The apparatus...
The liquid crystal cholesteryl oleate (ChO) has been studied through the measured electric permittivity (ε′) and loss (ε″) over a vide range of temperature extending from its crystal phase to isotropic phase and at different spot frequencies in the range 1.25 to 200 MHz. The dipole moment, dielectric relaxation time and other related parameters have been evaluated and interpreted in terms of molecular...
