investigate properties of
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,
gratings, and laser beam steering
devices, and consult for numerous
companies on LCD product
development and intellectual property
We use a variety
of experimental tools, including:
electro and magnetooptic tools such as
dynamic light scattering, ellipsometry, and
optical activity; polarizing optical
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
Department of Education, the Partner
Fund adminstered by the French Foreign
Ministry, and industry.
