Structure, dynamics and thermodynamics of confined water

Water is the essence of life and various properties of water molecules have intrigued researchers from time immemorial. The speaker studies various translational and orientational dynamics of water molecules confined inside a carbon nanotube using atomistic molecular dynamics simulation and tries to understand the thermodynamics of water entering inside a hydrophobic nanotube by calculating the Helmholtz free energy of water using two-phase thermodynamic method. Based on these studies, the speaker has proposed a mechanism of water permeation in helium impermeable graphene oxide (GO) membrane using the calculation of potential of mean force (PMF). PMF calculations of the oxidized part of the GO sheets in helium and oxidized part of the GO in water will be discussed highlighting the difference in their permeation path.
