Description:

investigate fundamental properties of nematic and smectic liquid crystals, as well as mixtures of surfactant molecules in aqueous solutions. Projects include symmetry effects and polarizations, ferroelectric and antiferroelectric liquid crystals, liquid crystalline order in confined geometries, interfacial effects, phase transitions and critical phenomena, nonlinear behavior, nanoscopic behavior, and liquid crystals in a microgravity environment. Additionally, we are engaged in the study of the statics and dynamics of liquids in a controllable gravitational environment. We develop liquid crystal devices, including displays, electrically-controlled optical gratings, and laser beam steering devices, and consult for numerous companies on LCD product development and intellectual property issues. We use a variety of experimental tools, including: electro and magnetooptic tools such as dynamic light scattering, ellipsometry, and optical activity; polarizing optical microscopy; differential scanning calorimetry and modulated DSC; dielectric probes; synchrotron x-ray scattering at the National Synchrotron Light Source; scanning tunneling and atomic force microscopy (AFM); and near field scanning optical microscopy (NSOM). We are funded by the National Science Foundation (NSF), the U.S. Department of Energy (DoE), the U.S. Department of Education, the PartnerUniversity Fund adminstered by the French Foreign Ministry, the US-Israel Binational Science Foundation, and industry. microphotograph of unaligned nematic liquid crystal.
