A liquid crystalline compound, 4-(tetradecyloxy)-N-(4-hexyloxyphenyl)-2-hydroxybenzalimine (THPHBI) has been synthesized and characterised. Phase transition temperatures of 4-(tetradecyloxy)-N-(4-hexyloxyphenyl)-2- hydroxybenzalimine were determined by polarizing microscopy, differential scanning calorimetry and inverse gas chromatography technique (IGC). The retention diagrams of n-butyl acetate (nBA), iso-butyl acetate (IBA), benzene (B), toluene (T) and ethylbenzene (EB) were plotted between 40 and 160 o C by IGC. Specific retention volume, 0 Vg , weight fraction activity coefficient, ∞ Ω1 , Flory Huggins polymer-solvent interaction parameter, ∞ 12 χ , equation of state polymer-solvent interaction parameter, ∗ 12 χ and effective exchange energy parameter, Xeff were determined for studied solvents. Then, the exchange enthalpy parameter, X12 and entropy parameter Q12 were determined by using a relation for the enthalpy interaction parameter, ∗ h χ of the equation of state theory, which was arranged for the IGC.

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.
