Dynamic surface tension control in molten aluminum shows a controllable 15–30% fluctuation under extreme loads, paving the way for better wetting and interface management in engineering processes.

By combining high-resolution electrostatic mapping with molecular dynamics simulations, we investigated the behavior of these surface-trapped ionic charges. We found that they spread across the surface with remarkable mobility. Their two-dimensional diffusion exceeds that of ions in bulk water, with the limiting factor being the friction between the ionic solvation shell and the solid.
