Opis:: The Investigations of Twist Grain Boundary (TGB) phases in liquid crystals exhibits in different types of structural groups. In this study, these new findings present in the binary mixture of highly chiral liquid crystal, Cholesteric Nonanoate (CN) and nematic liquid crystal, N-(4-Ethoxy benzylidine)-4-butyle aniline (EBBA). The Differential Scanning Calorimeter (DSC) has shown the thermodynamic phase transition of binary mixture at different scanning rate. At the other hand Optical studies of Twist grain boundary phases has also shown different type of textures. The domain of existence of TGB has exhibited with the weight percentage of EBBA is increased in highly chiral liquid crystals. This is very excited fact that the temperature range of type of TGB (TGBA*) phase is different at the different scanning rate. In the optical investigation we found new phases in cooling cycle as compare to the heating cycle.

Opis:: The acoustical parameters for the binary liquid mixtures containing Pyrazoline derivatives in DMF have been estimated at 303.15 K, from the measured values of ultrasonic velocity (U), density (ρ) and viscosity (η). From these data some of acoustical parameters such as adiabatic compressibility (β), free length (Lf), acoustic impedance (Z), Rao’s constant (R), molar compressibility (W), relaxation time (τ), free volume (Vf) and internal pressure (πi), etc., have been computed using the standard relations. The results have been discussed in terms of molecular interactions.
