Penn Researchers Add Another Tool In Their Directed Assembly Toolkit
2013-11-12 12:43:22

University of Pennsylvania An interdisciplinary team of University of Pennsylvania researchers has already developed a technique for controlling liquid crystals by means of physical templates and elastic energy, rather than the electromagnetic fields that manipulate them in televisions and computer monitors. They envision using this technique to direct the assembly of other materials, such as nanoparticles. Now, the Penn team has added another tool to its directed assembly toolkit,...

Issue highlights recent advances in liquid crystal material research for photonic applications Liquid crystals (LCs), a state of matter that has properties between those of a conventional liquid and those of a solid crystal, are fast becoming a household name thanks to their widespread use in television, smartphone and computer displays. As such, research and development in the area of liquid crystal materials (LCMs) has also been rapidly progressing in recent years. To highlight...

Chemists at Vanderbilt University have created a new class of liquid crystals with unique electrical properties that could improve the performance of digital displays used on everything from digital watches to flat panel televisions. The achievement, which is the result of more than five years of effort, is described by Professor of Chemistry Piotr Kaszynski and graduate student Bryan Ringstrand in a pair of articles published online on Sept. 24 and Sept. 28 in the Journal of Materials...

In order to successfully fabricate a commercial Liquid Crystal Display, uniform orientation of the liquid crystal (LC) molecules is required. Traditionally this molecular alignment of liquid crystal is achieved by physically or chemically treating the surface. A simple method used to achieve preferred orientation is rubbing but this may produce dust, static charging and mechanical damage which deteriorates the production yield. One of the more attractive alternatives to rubbing is the...
