| Popis: | Tribocharging increases due to deformation and penetration of surface asperities, enlarging the real contact area. These experimental results translate into a theoretical description of particle charging that resolves the surface topology. Based on these findings, we propose a model that predicts the dependence of the particles' saturation charge on the impact velocity and surface roughness. Comment: 5 pages, 4 figures |
