Nematic ordering in a system of rods, Physical Review A: 19 (3), 1225-1230 (1979)
Use of either sulphuric or phosphoric acid yields a chiral
nematic phase, but hydrochloric acid hydrolysis gives a viscous suspension that forms a birefringent, glassy phase after a "post-sulphation" treatment (Araki et al., 2000).
Nonetheless, for the widely used
nematic liquid crystals that his group has investigated, "nothing like this has ever been done before," Patel asserts.
The highly ordered but non-crystalline chiral
nematic state has only recently gained attention.
Using the
nematic tensor order parameter [6], we described LC orientational ordering as follows:
The chosen
nematic LC was GT3-24002 from Merck, synthesized with a wide
nematic phase temperature range and with a clearing temperature of ~173[degrees]C, which makes this LC material suitable for many practical purposes [19].
In this case, it is the electronic orbitals that enter the
nematic state as the temperature drops below a critical point.

Nematic Liquid Crystals: Theory, Simulation, and Experiment
Figures 1(a)-(c) depict three commonly occurring phases: Smectic,
Nematic and Cholesteric (chiral-Nematic).
We used the
nematic liquid crystal CL036 (LC) from Qingdao Intermodal Co., Ltd., which is a mixture of 4-cyanobiphenyls with alkyl chains of different lengths.

nematic displace, and smart phone products.
