摘要:
Molecular dynamics simulations are used to investigate the behaviour of liquid acetonitrile confined within [GRAPHICS] nm diameter silica pores. Different approaches for characterising the liquid structure in the pores are examined and compared. The effect of surface chemistry on the liquid layering at the pore interface is discussed based on simulations in pores with modified interactions. Finally, the dynamical properties, specifically acetonitrile reorientation, are also considered and their dependence on molecule position is probed.
