[LA-SiGMA] LASiGMA Seminar - Dr. Andrey Dobrynin, Wednesday April 3, 3:30 p.m.

Dear All,

Dr. Andrey Dobrynin, of the University of Connecticut will be giving a  
seminar Wednesday, April 3rd, at 3:30 p.m. in Johnston Hall, room 338  
at Louisiana State University. The title of his talk is "Electrostatic  
Interactions in Polymers and Soft Matter".

Abstract:
Electrostatic interactions between macroions play an important role in  
different areas ranging from materials science to biophysics.  They  
are main driving forces behind layer-by-layer assembly technique that  
allows fabrication of multilayer films from synthetic  
polyelectrolytes, DNA, proteins and nanoparticles. They are  
responsible for the extremely low fiction coefficient between  
biological surfaces such as articular cartilage coatings. In this  
talk, using results of the molecular dynamics simulations and scaling  
analysis, I will show what effect electrostatic interactions have on a  
collapse of polyelectrolyte chain in a poor solvent conditions for the  
polymer backbone, on a layer-by-layer assembly of charged  
nanoparticles and polymers on porous substrates, and on friction and  
lubrication between brush covered surfaces.

ANDREY DOBRYNIN is Professor of Physics at the Institute of Materials  
Science and Department of Physics at the University of Connecticut in  
Storrs, CT. He received his B.S. (1987) and Ph.D. (1991) degrees in  
Polymer Physics from the Moscow Institute of Physics and Technology,  
Moscow, Russia.  He joined the faculty at the University of  
Connecticut in 2001. His research focuses on polyelectrolyte solutions  
and gels, charged polymers at surfaces and interfaces, electrostatic  
interactions in biological systems, soft-matter physics and  
biophysics.  For his work on charged polymers Prof. Dobrynin was  
elected a Fellow of the American Physical Society. More information is  
available from his research group web page: www.ims.uconn.edu/~avd

The seminar will be a live broadcast from Louisiana State University,
