Specific Volume and Ultrasonic Velocity Studies of the Liquid Crystal N-(p-n-hexyloxybenzylidene)-p-n-butylaniline (HXBBA)
Specific volume and ultrasonic velocity measurements have been carried out on the liquid crystal N-(p-n-hexyloxybenzylidene)-p-n-butylaniline in the isotropic, nematic, smectic A, smectic B and smectic G phases. The variation of the specific volume with temperature shows that the corresponding transitions are of first order. Thermal expansion coefficients have been calculated for all the mesoph...
متن کاملOpto-optical modulation in N-(p-methoxybenzylidene)-p-butylaniline.
A method of opto-optical modulation in liquid crystals is reported. An Ar(+) laser beam is employed to modulate a second He-Ne laser. The highest frequency achieved was 1.5 x 10(3) pulses per second with input modulating powers smaller than 10 mW. A homeotropic N-(p-methoxybenzylidene)-p-butylaniline liquid-crystal cell was employed as the nonlinear medium.
متن کاملHigh pressure measurements of the refractive indices of two nematic liquid crystals
2014 The refractive indices of two nematogens, 4-methoxy-benzylidene-4’-n-butylaniline (MBBA) and 4-n-pentyl-4’-cyanobiphenyl (5CB), have been measured throughout their nematic ranges at pressures up to 2 kbar and temperatures up to 70 °C in the first substance and up to 5 kbar and 145 °C in the second. Measurements were made at 03BB = 5 890 Å, using a sensitive interference fringe technique. R...
متن کاملTheoretical studies on corrosion inhibition of N-aroyl-N’-aryl thiourea derivatives using conceptual DFT approach
In this paper, quantum chemical parameters at density functional theory (DFT) B3LYP/6-31G** (d,p) level of theory were calculated for three organic corrosion inhibitors [N-benzoyl-N-(p-aminophenyl) thiourea, N-benzoyl-N-(thiazole) thiourea and N-acetyl-N-(dibenzyl) thiourea. The calculated molecular descriptors such as the HOMO, LUMO, dipole moment, chemical potential (μ), chemical hardness (ղ)...
متن کاملDielectric Relaxations and Intermolecular Interaction in Several Binary Nematic Mixtures of P-methoxybenzylidene - P'-n-butylaniline and Non-mesogenic Compound
Anisotropic dielectric relaxations in several binary nematic mixtures of MBBA and non-mesogenic compound oriented by magnetic field were measured in the frequency range of 300 Hz to 3 MHz. Viscosity measurements were also made in the isotropic state. Non-mesogenic compounds used were non-linear shaped molecules such as chloroform, m-xylene, and 1,3,5-trimethylbenzene, and nearly linear shaped m...
