AND NAGAPPA %J International Journal of Machine Intelligence %D 2011 %I Bioinfo Publications %X The binary mixture of Cholesteryl ethyl corbonate (CEC) and Terephthal-bis-p-n-Tetradecylaniline (TB14A) exhibits a twisted grain boundary (TGB) phase and smectic polymorphic phases. The mixture exhibits TGB-A and TGB-C phases in different concentrations and at different temperatures. Mixtures with higher concentrations of TB14A exhibit I ¨C Ch - TGB-A - TGB-C - Sm A - Sm I - Sm F phases sequentially when the specimen is cooled from its isotropic melt. The existence of different TGB phases and polymorphic smectic phases are confirmed by DSC and optical microscopic studies. %K Optical textures %K Renn and Lubbensky model %K Smectic and Cholesteric mixture %K TGB phase %U http://www.bioinfo.in/uploadfiles/13252345393_3_6_IJMI.pdf
