COMPUTER-SIMULATION STUDY OF THE WETTING BEHAVIOR AND LINE TENSIONS OF NANOMETER-SIZE PARTICULATES AT A LIQUID-VAPOR INTERFACE

We study the behavior of nanometer size particulates at a liquid-vapor interface by means of molecular dynamics simulations. We propose a me thodology for computing the line tension using computer simulations, a nd present new data for the wetting of particulates at a planar liquid -vapor interface, as a function of particulate size. For the sizes con sidered in this work the line tension is negative and influences the w etting behavior of particulates at the liquid-vapor interface.
