Flows at the surface of solids have described by surface diffusion or a melted nanometer-thick layer, driven by capillarity or an external applied pressure. Such a flow could be in theory driven by a gradient of surface concentration. Such a phenomenon is described theoretically, and compared with the experience of gold-nanoparticle engulfing in a wafer of fused silica at high temperature.
