Dr Subhasis Adhikari, who will be visiting our group that day will give the following talk:

“Temperature Dependent Heterogeneous Single Molecule Dynamics in A Polymer”

In the study of glassy polymer systems, there has been a long debate about the nature of heterogeneity of the material near glass transition temperature. There exist essentially two pictures of spatial and temporal heterogeneities. In this presentation I will report results on this issue by analyzing the rotational diffusion of single perylene diimide dye molecules in glassy polymer poly (methylacrylate).
