Liquid Crystals

Organic light-emitting diode technologies (OLEDs), a key technological feature in the display of many models of mobile phones and televisions already provide great image quality and high-resolution. But are they as efficient as they can be? Inspired by methods used in liquid-crystal technology, Kent State University researchers in the College of Arts and Sciences have developed new ways to improve OLED efficiency even more.

Congratulations to physics graduate student Shaikh Shamid, whose paper entitled "Theory of polar blue phases" has been highlighted in Liquid Crystals Today, the magazine of the International Liquid Crystal Society. This publication is co-authored by Shaikh's PhD advisors, Profs. David Allender (Physics) and Jonathan Selinger (Chemical Physics). 

What does it take to become great in your field?  Certainly motivation, dedication and creativity are important, but what about inspiration?  For young scientists that inspiration can come from a variety of places, including interactions with colleagues and especially the top scientists in their field.

A team of researchers at Kent State University have discovered a new version of a widely used scientific technique. The technique is electrophoresis — in which an applied electric field is used to move particles dispersed in a fluid — and the new idea is to use a liquid crystal as the carrier fluid. The result is increased versatility, which may lead to new uses in display technologies, microfluidic devices and other applications.
