Wide Temperature Range Blue Phases
In 2005, researchers from the Centre of Molecular Materials for Photonics and Electronics at the University of Cambridge reported their discovery of a class of blue-phase liquid crystals that remain stable over a range of temperatures as wide as 16-60 °C. The researchers showed that their ultrastable blue phases could be used to switch the color of the reflected light by applying an electric field to the material, and that this could eventually be used to produce three-color (red, green, and blue) pixels for full-color displays. The new blue phases are made from molecules in which two stiff, rod-like segments are linked by a flexible chain, and are believed to be stabilized due to flexoelectricity.
Furthermore, electro-optical switching with response times of the order of 10−4 s for the stabilized blue phases at room temperature has been shown.

Famous quotes containing the words wide, temperature, range, blue and/or phases:
“The beasts, the fishes, and the winged fowls
Are their males’ subjects and at their controls:
Man, more divine, the master of all these,
Lord of the wide world and wild watery seas,
Indued with intellectual sense and souls,
Of more pre-eminence than fish and fowls,
Are masters to their females, and their lords:
Then let your will attend on their accords.”
—William Shakespeare (1564–1616)
“The bourgeois treasures nothing more highly than the self.... And so at the cost of intensity he achieves his own preservation and security. His harvest is a quiet mind which he prefers to being possessed by God, as he prefers comfort to pleasure, convenience to liberty, and a pleasant temperature to that deathly inner consuming fire.”
—Hermann Hesse (1877–1962)
“No doubt, the short distance to which you can see in the woods, and the general twilight, would at length react on the inhabitants, and make them savages. The lakes also reveal the mountains, and give ample scope and range to our thought.”
—Henry David Thoreau (1817–1862)
““... Can poet’s thought
That springs from body and in body falls
Like this pure jet, now lost amid blue sky,
Now bathing lily leaf and fish’s scale,
Be mimicry?””
—William Butler Yeats (1865–1939)
“That man is to be pitied who cannot enjoy social intercourse without eating and drinking. The lowest orders, it is true, cannot imagine a cheerful assembly without the attractions of the table, and this reflection alone should induce all who aim at intellectual culture to endeavor to avoid placing the choicest phases of social life on such a basis.”
—Mrs. H. O. Ward (1824–1899)
