New type of liquid crystal identified; Holds promise of faster, lower priced liquid crystal displays

15.06.2004


A new type of liquid crystal - recently discovered by a research team that includes a Kent State University professor - holds the promise of faster liquid crystal displays at a lower price.



A new liquid crystal phase – the biaxial nematic liquid crystal - which is likely to revolutionize the liquid crystal display technology, has been discovered by three researchers, Dr. Satyendra Kumar, professor of physics at Kent State; Dr. Bharat R. Acharya, of Platytus Technologies, Madison, WI; and Dr. Andrew Primak, of Pacific Northwest National Lab, Richland, WA.

Currently, the liquid crystal displays used in most laptops and televisions make use of the uniaxial nematic liquid crystal. It is predicted that the use of biaxial nematic liquid crystals will make these products more than 10 times faster and will allow for cost-saving measures.


The existence of the biaxial nematic liquid crystal was predicted 34 years ago by IBM’s Thomas J. Watson Research Center in Yorktown Heights, N.Y.

However, according to Acharya, "There was no evidence of the existence of biaxial nematic liquid crystals made of single molecules until recently. Other types of more complex micellar biaxial liquid crystals were found previously by Kent State researchers, but, until now, none had the right optical properties for use in displays and photonics devices."

A paper reporting how the researchers used small-angle X-ray diffraction technique to discover the biaxial nematic liquid crystal appeared in the April 9 issue of the prestigious Physical Review Letters. Kent State researchers also presented their initial evidence in 2000 at the March meeting of the American Physical Society. This research will be presented by Kumar in an invited talk at the International Liquid Crystal Conference in Slovenia on July 6, 2004.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
