Our research work focuses on structure and dynamics of soft condensed matter such as room-temperature ionic liquids, electrolyte solutions, room-temperature polar & non-polar liquids, deep-eutectic solvents and lipid-membranes. We use state-of-the-art computer simulations, including all-atom, coarse-grained and ab-initio molecular dynamics, and apply various theoretical techniques to elucidate the physicochemical properties of these systems.
1. Bulk and Interfacial Properties of Ionic Liquids: Modern ionic liquids (ILs) are novel materials that are being scrutinized for their uses in energy efficient devices e.g. electrochemical cell, super capacitors etc. Our group uses the means of molecular dynamics simulations and concepts of statistical thermodynamics to understand the microscopic structure of ionic liquids in bulk and at interface. We also focus on the study of IL+co-solvent mixtures and effect of external stimuli such as pressure, temperature and electric potential on the structure of ionic liquids.
2. Structure and Dynamics of Deep Eutectic Solvents: Deep eutectic solvents (DESs) are an emerging class of multicomponentliquids, sharing several physicochemical properties with ionic liquids. In our group, we focus on exploring the structural and dynamic aspects of various DESs by using MD simulation techniques. Appreciating the behaviour of these solvents in neutral and charged confinement is also a part of our research.
3. Structure and Dynamics of Biological Membranes: We carry out multiscale molecular dynamics simulations to examine the effects of small drugs, amphiphilic compounds, ILs and DESs on the structure and stability of biomimmetic homogeneous and heterogeneous lipid membranes.
4. Quantum Chemical Studies: We study the effects of internal and external donors on the performance of Ziegler-Natta catalyst for polymerisation of olefin using ab-initio methods. We also carry out quantum chemical computational studies to study their catalytic activity.
