Physical Chemistry, Polymer Physics, and Material Science

We are equipped to observe interactions between electromagnetic radiation and matter that allows the study of local temporal fluctuations on a molecular scale. The ability to measure translation, rotation, vibration, flexure, and flow in molecules has been a breakthrough in such widely separated fields as fluid dynamics, polymer physics, colloid science, molecular biology, and biophysics. Our laser light scattering laboratory is one of the best equipped in the world.

The fundamental techniques involve photon correlation spectroscopy, transient electric birefringence, fluorescence recovery after photobleaching, and holographic relaxation spectroscopy. Together with time resolved small-angle X-ray scattering (SAXS) using the Brookhaven National Synchrotron Light Source and other methods such as Raman scattering, we have been studying the behavior of thermodynamic and transport properties of polymers and colloids near phase separations and the dynamics and conformation of polymers, proteins, micelles, DNA, liquid crystals, vesicles, muscle filaments, fibers, and micro- emulsions.

With instrumentation awards from the Department of Energy and the National Science Foundation, we have established a SAXS facility at Stony Brook and an Advanced Polymers Beamline at X27C, at the National Synchrotron Light Source. Furthermore, another beamline, the ChemMat CARS, is being designed and constructed at the Advanced Photon Source, at the Argonne National Laboratory.

We have achieved the first laser light scattering characterization of Teflon since its invention more than 50 years ago, observed single-molecule coil-to-globule transition in a polymer solution at a concentration of 30 ng/mL, and measured the instantaneous electrophoretic mobility of large DNA fragments in pulsed- field gel electrophoresis by means of movements of fluorescence pattern after photobleaching (U.S. Patent #5,215,883), as well as the melt viscosity of Teflon at 380 °C.
