Examples
-
One of the ordered phases is the "nematic" phase, in which the molecules move as if in an ordinary three-dimensional liquid, but with their axes mainly pointing the same way.
-
The magazine New Scientist reports researchers have developed a prototype of such glasses, each lens of which consists of a five-micron layer of nematic liquid crystal sandwiched between two pieces of glass.

-
Further development of this technique enabled us to synthesize helical polyacetylene that consists of clockwise or counterclockwise helical structure of fibrils, by use of chiral nematic liquid crystals.
-
We found that an equimolar mixture of nematic liquid crystals bearing a phenylcyclohexyl moiety was useful for that purpose.
-
Pierre-Gilles de Gennes developed the theory for the behavior of liquid crystals and their transitions between different ordered phases (nematic, smectic, etc).
-
One of the phases of a liquid crystal, called nematic, can be compared with a ferromagnet, where the atoms, which are themselves tiny magnets, are ordered so that they point in essentially the same direction - with slight variations.
-
De Gennes himself made his chief contributions to our knowledge of liquid crystals when he explained what is termed anomalous light scattering from nematic liquid crystals.
-
A liquid of nematic "droplets" viewed through a polarisation microscope.
-
They offer up to 10 times higher contrast ratios when viewed from an angle as compared to mainstream monitors that use twisted nematic TN technology.
