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 , 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 .
In this case, it is the electronic orbitals that enter the nematic
state as the temperature drops below a critical point.
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.
can be used on but not limited to LED room lighting, LED TV, laptop-illuminated keyboard, LED laptop, luminescence identification, super-twisted nematic
displace, and smart phone products.
