(Top) Composite SLD and (bottom) hydration profiles for the silica nanoparticle on silicon system. Solid lines represent the reconstructed profiles (σ = 15 Å) and dashed lines the profiles of the original model. Calculation of the original model reflectivity curves was performed by approximating the parabolic profile with 20 layers and by assuming a layer roughness of 10 Å under the Névot–Croce approximation (Névot & Croce, 1980). |
