Fig. 6

Absolute difference between the pressure calculated in the nanoparticle or in the vicinity of the cavity, and the Laplace pressure as a function of the nanoparticle/cavity diameter, with no extra applied pressure. Top (bottom) graphs show results for nanoparticles (cavities). The Laplace pressure is computed using either surface energy γ (left graphs) or surface stress Γ (right graphs). Full lines with symbols show results obtained with γ or Γ values corresponding to each diameter, while values at diameters equal to 20 nm are used to obtain data associated with dashed lines
