Ab initio molecular dynamics simulations proved to be a powerful tool for following the flipping between a liquid metal and electrolyte with atomistic resolution at a femtosecond timescale, the validity of which has been supported by an agreement between simulated and experimental photoelectron spectra of these systems. Direct measurements of the flipping phenomena may prove difficult due to the very small nanometer size of the metallic and electrolyte domains. Nevertheless, a feasible strategy to probe the flipping time indirectly may be a pumpprobe experiment where one would follow the relaxation of the photoexcited system back to equilibrium. In order to attain the temporal as well as the spatial resolution ultrafast (attosecond) X-ray diffraction -a technology that is now becoming within reach -is likely to be a game changer.
