A Relation for Nanodroplet Diffusion on Smooth Surfaces

A Relation for Nanodroplet Diffusion on Smooth Surfaces

In this work, we study the diffusion of nanodroplets on smooth surfaces through molecular dynamics (MD) simulations and theoretical analyses. Molecular dynamics simulations show that nanodroplet surface diffusion is different from that of single molecules and solid particles. The dependence of nanodroplet diffusion coefficient on temperature undergoes a transition from linear to nonlinear as th...

Geodesic Bifurcation on Smooth Surfaces

Within Riemannian geometry the geodesic exponential map is an essential tool for various distance related investigations and computations. Several natural questions can be formulated in terms of its preimages, usually leading to quite challenging nonlinear problems. In this context we recently proposed an approach for computing multiple geodesics connecting two arbitrary points on two-dimension...

Molecular dynamics simulations of nanodroplet spreading on solid surfaces, effect of droplet size

Abstract Molecular dynamics simulations were performed to study the spreading characteristics of nano-sized droplets on solid surfaces. The spreading behavior was analyzed in terms of the temporal evolution of the dynamic contact angle and spreading diameter for wettable, partially wettable and nonwettable surfaces. The computational model was validated through qualitative comparison with the m...
