tures at a surface point. A Gaussian curvature nearing zero can be predominantly attributed to either κ 1 or κ 2 being zero at a specific local point on the droplet surface. The range of mean and Gaussian curvatures, from positive to negative, reflects a noticeable deformation of the nanodroplet surface, primarily due to the formation of surface protrusions driven by the self-assembled tbp on the surface of the nanodroplet.
