Modeling of micro- and nanodroplets

In this review, a formula that determines the curvature-dependent surface tension in a droplet with two phases has been discussed. Taking into account the dependence of the surface tension on the system size, nonlinear differential equations describing the droplet profile have been derived. It has been shown that, if the droplet size is not too large compared with the thickness of the surface layer (micro- or nanodroplets), the dependence of the surface tension on the curvature is extremely important.
