Transport Of Polar And Non-polar Solvents Through a Carbon Nanotube

Transport of water through narrow pores is important in chemistry, biology and material science. In this work, we employ atomistic molecular dynamics (MD) simulations to carry out a comparative study of the transport of a polar and a non-polar solvent through a carbon nanotube (CNT). The flow of water as well as methane through the nanotube is estimated in terms of number of translocation events and is compared. Transport events occurred in bursts of unidirectional translocation pulses in both the cases. Probability density and cumulative probability distribution functions are obtained for the translocated particles and particles coming out from same side with respect to the time they spent in the nano channel.
