Abstract:
The anion exchange membranes (AEM) are generally simulated using ab initio or reactive molecular dynamics (MD) simulation approach. However, the applicability’s of these methods are still limited by computational cost, availability of force-field, transferability, etc. Empirical force-field based MD simulation can predict structure and dynamics at a lower computational cost. Considering polarizable models for hydroxide ion and water in combination with a non-polarizable model of AEM polymer, we simulate hydrated AEM. The simulated solvation structure and non-reactive dynamics are in reasonable agreement with literature. A detailed study has revealed that the diffusion of the hydroxide ion and water approximately follow hydrodynamics.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
