Trace amount of solvents such as benzene, toluene, ethylbenzene, n-propylbenzene, isopropylbenzene and chlorobenzene were passed through the gas chromatography column loaded with a new synthesized and characterized liquid crystal compound, 5-decyloxy-2-[[[4-hexyloxyphenyl]imino]methyl]phenol (DHOPIMP) which is coated on Chromosorb W. The retention diagrams of the solvents on the liquid crystal were plotted by means of specific retention volumes, Vg o at temperatures between 130 and 150 o C by inverse gas chromatography. The weight fraction activity coefficient at infinite dilution of the solvents, ∞ Ω1 , the liquid crystal-solvent interaction parameters of Flory-Huggins, ∞ 12 χ , and equation of state, ∗ 12 χ and effective exchange energy parameter, Xeff , were obtained. In addition, the partial molar heats of sorption, ΔH1,sorp and mixing, ∞ ΔH1 were determined. Phase transition temperatures of DHOPIMP were determined by polarizing microscopy and differential scanning calorimetry.

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.
