The dielectric relaxation and anisotropy properties of 4-cyano-4'-pentylbiphenyl and salicylaldimine compound (LC1) liquid crystals have been investigated. The polarizing microscopy and differential scanning calorimetry results show that the chiral salicylaldimine compound (LC1) exhibits enantiotropic SmC* mesophases. The dielectric anisotropy of the liquid crystals changes from positive type to negative type. The critical frequency values of dielectrical anisotropy for 4-cyano-4'- pentylbiphenyl and salicylaldimine compound (LC1) were found to be 693.84 and 577.61 kHz, respectively. The dielectric anisotropy value of 5CB/LC1 liquid crystal composite is lower than 5CB liquid crystal. It is evaluated that the 5CB/LC1 composite liquid crystal gives new dielectrical anisotropy and electrical properties.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
