The morphology of the intrinsic droplet surface water molecules is characterized by computing the surface curvature and areas, using the protocol described in the methodology section. The curvature and area calculations were carried out on the largest water cluster, formed primarily by the intact water molecules. Three distinct surface curvature descriptors namely, mean curvature, Gaussian curvature, and squared curvedness of the droplet were calculated. Figure shows the distributions of instantaneous mean and Gaussian curvature of water droplet surface points at the time interval of t = 10 ns. The positive and negative values show the convex and concave facets of the surface, respectively. A mean curvature value of zero indicates balanced curva-FIG. : Intrinsic mean and Gaussian Curvature distribution of the local points on the triangulated water droplet surface in w/o and w/t/o systems after 10 ns of molecular dynamics simulations at 298 K temperature. The curvature analysis is performed on the largest water cluster which is separated from the extracted and dangling surface water molecules using the cluster analysis as described in the Material and Methods section.
