Layer-by-layer and intrinsic analysis of molecular and thermodynamic properties across soft interfaces
Interfaces are ubiquitous objects, whose thermodynamic behavior we only recently started to understand at the microscopic detail. Here, we borrow concepts from the techniques of surface identification and intrinsic analysis, to provide a complementary point of view on the density, stress, energy, and free energy distribution across liquid ("soft") interfaces by analyzing the respective contributions coming from successive layers. © 2015 AIP Publishing LLC
How Is the Surface Tension of Various Liquids Distributed along the Interface Normal?
The tangential pressure profile has been calculated across the liquid

vapor interface of
five molecular liquids, i.e., CCl

, acetone, acetonitrile, methanol, and water in mole
cular
dynamics simulations using a recently developed method. Since the value of the surface
tension is directly related to the integral of this profile, the obtained results can be interpreted
in terms of the distribution of the surface tension along the
interface normal, both as a
function of distance, either from the Gibbs dividing surface or from the capillary wave
corrugated real, intrinsic liquid surface, and also in a layerwise manner. The obtained results
show that the surface tension is distributed
in a 1

nm wide range along the interface normal,
and at least 85% of its value comes from the first molecular layer
of
the liquid in every case.
The remaining, roughly 10% contribution comes from the second layer, with the exception of
methanol, in whic
