Paranematic
WebThe orientational order of the confined liquid crystals, quantified by the uniaxial nematic ordering parameter, evolves continuously between paranematic and nematic states, in contrast to the discontinuous isotropic-to-nematic bulk phase transitions. WebAs adjectives the difference between nematic and paranematic is that nematic is (physics chemistry of certain liquid crystals) whose molecules align in loose parallel lines …
