National Synchrotron Light Source Seminar

"Surface Induced Order at Liquid and Polymer Interfaces"

Presented by Benjamin Ocko, Brookhaven National Laboratory

Tuesday, September 13, 2011, 9:30 am — Seminar Room, Bldg. 725

Surface freezing, the formation of a one or two molecular layers thick crystalline film on the surface of a melt, occurs in long-chain hydrocarbons such as n-alkanes and alcohols over a range of temperature where the bulk remains molten. More recently, related phenomenon has also been observed at solid interfaces and at surfactant covered surfaces of water. I will provide an overview of surface freezing in a variety of systems and provide a basis for understanding this phenomenon. I will also report recent work on the ordering of conjugated polymers at the nanostructured interfaces. Work at Brookhaven National Laboratory is supported by US Department of Energy,
