We study the phenomenon of migration of the small molecular weight component of a binary polymer mixture to the free surface using mean field and self-consistent field theories. By proposing a free energy functional that incorporates polymer-matrix e... Read More about Elasticity dominated surface segregation of small molecules in polymer mixtures.

Delayed self-regulation and time-dependent chemical drive leads to novel states in epigenetic landscapes (2014)
Journal Article

The epigenetic pathway of a cell as it differentiates from a stem cell state to a mature lineage-committed one has been historically understood in terms of Waddington's landscape, consisting of hills and valleys. The smooth top and valley-strewn bott... Read More about Delayed self-regulation and time-dependent chemical drive leads to novel states in epigenetic landscapes.

Monte Carlo Simulation of Geminate Pair Recombination Dynamics in Organic Photovoltaic Devices: Multi-Exponential, Field-Dependent Kinetics and Its Interpretation (2014)
Journal Article

Monte Carlo simulations are used to examine charge-transfer (CT) state recombination dynamics considering the effects of energetic disorder and bulk heterojunction morphology. Strongly biexponential recombination kinetics were observed, in agreement...
