Lastly, the skin supersolidity matters the performance and functionality of water droplets. Fig. and show the linear dependence of the ωH and the TN supercooling of the sized droplets or molecular clusters. The TN depression is measured using differential scanning calorimetry (DSC) and nuclear magnetron resonance spectroscopy (NMR) . The inset shows the freezing delay of a droplet deposited on a nanostructured Al surface having a higher surface curvature took 70 sec longer to freeze at 269 K than the contrast deposited on a smooth Al surface . The trends of the ωH blueshift, electron lift τ variation, and the TN depression depend linearly on the skin volume ratio, ∆ωH(N) ∝ ∆τ(N) ∝ -∆TN(N) ∝ F(R), which indicate their molecular undercoordination and the supersolid skin dominance.
