Liquid Crystal Group
at Case in front of
Rockefeller Physics Building, April, 2008
We
investigate 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), National
Aeronautics and
Space Administration (NASA) ,
the U.S. Department
of Energy (DoE), the Petroleum
Research Fund of the American Chemical Society,
and
industry.
