(a) The specific heat capacity c_p(T) of water confined in the narrowest SiO₂ pore reported in Nagoe et al.45 (b) By integrating the latter function c_p(T), the energy of nanoconfinement is evaluated as . (c) The inverse function T=f⁻¹(Δh) provides the temperature corresponding to a given energy Δh; hence, it can be used in combination with the experimental results from Chen et al.1 where the diffusion coefficient (in narrow SiO₂ pores) is given as a function of T. (d) The ratio between the diffusion D_c of fully confined water and the bulk diffusion D_b of water, D_C/D_B=g(Δh), is reported and the corresponding values for all the considered configurations are shown, where g(Δh)<0.15.
