Inherent structure analysis reveals origin of breakdown of Stokes-Einstein relation in aqueous binary mixtures
Shubham Kumar, Sarmistha Sarkar, Biman Bagchi
We show by inherent structure (IS) analysis that the sharp composition dependent breakdown of the Stokes-Einstein relation correlates surprisingly well with an equally sharp non-mo…
Translation-Rotation Coupling in the Dynamics of Linear Molecules in Water
Anjali S Nair, Puja Banerjee, Sarmistha Sarkar +1
We study by computer simulations the coupled rotational and translational dynamics of three important linear diatomic molecules, namely, carbon monoxide (CO), nitric oxide (NO) and…
Transport in a binary mixture of non-spherical molecules: Is hydrodynamics at fault?
Sarmistha Sarkar, Tuhin Samanta, Biman Bagchi
We consider a new class of model systems to study systematically the role of molecular shape in the transport properties of dense liquids. Our model is a liquid binary mixture wher…
Nanoscale heterogeneous phase separation kinetics in binary mixtures: Multistage dynamics
Milan K. Hazra, Sarmistha Sarkar, Biman Bagchi
In order to find a measure of the dynamical features of phase separation kinetics during spinodal decomposition of a liquid binary mixture (like water and cyclohexane , water and 2…
Correlation between inherent structures and phase separation mechanism in binary mixtures
Sarmistha Sarkar, Biman Bagchi
Binary mixtures are known to phase separate via both nucleation and spinodal decomposition, depending on the initial composition and extent of the quench. Here we develop an energy…
