abstract = "This paper presents an experimental investigation of water droplet interaction with laser-textured superheated silicon surfaces featuring distinct micro- and nanostructures, depending on the Weber number and surface temperature. The results demonstrate that surface morphology significantly affects droplet dynamics. A comparative analysis shows that bare Si predominantly exhibits droplet breakup regimes, whereas the hierarchical topography of BlackSi promotes jet formation. Although all textured substrates display the film boiling regime, their Leidenfrost transition temperatures differ: BlackSi+HF exhibits a higher threshold associated with its purely microstructured morphology, while nanostructured BlackSi and BlackSi+ZnO demonstrate reduced thresholds due to superhydrophilicity and enhanced wicking capability. Thus, both micro- and nanosize features of the surface are key parameters governing heat and mass transfer processes during droplet impact on a superheated substrate.",
