Abstract
Thermodynamical and acoustical studies have been carried out in nematic liquid crystal (8CB) and zinc oxide (ZnO) nanoparticle doped 8CB mixtures. The effect of nanoparticle concentration on the ultrasonic velocity and density has been studied using density and sound velocity analyzer. Adiabatic compressibility, molar compressibility, sound velocity, acoustic impedance and intermolecular free length have been estimated. Density and sound velocity decrease with the increase of the temperature and ZnO concentration, however intermolecular free length increases with increasing the temperature and ZnO concentration. The results have been compared with pure nematic liquid crystal mixture.
