      abstract     = {Understanding of thermal effects on ion transport in porous
                      media is very important for environmental applications. The
                      movement of ions along a temperature gradient is named
                      thermophoresis or thermodiffusion. In nanoporous media,
                      where the interaction of ions with solid–liquid interfaces
                      has a significant influence on their migration, the
                      theoretical understanding of thermodiffusion is still
                      incomplete. Herein, we present experimental results for the
                      thermodiffusion of cations in saturated nanoporous silica by
                      the through-diffusion method. Both the experimental data and
                      theoretical analysis indicate that the temperature-induced
                      polarization of surface charges strongly influences ionic
                      transport. Stated simply, the electric field in a liquid
                      electrolyte confined in nanopores changes when the applied
                      temperature gradients are altered, thereby affecting the
                      motion of the nanoconfined ionic species. By applying an
                      external temperature field, the gradient of the surface
                      charge density leads to the charged aqueous species
                      exhibiting strong temperature gradient-dependent
                      electrophoretic mobility. When the thickness of the
                      electrical double layer is comparable to the size of the
                      nanopores, the theory used herein indicates that this kind
                      of nonisothermal ionic mobility is up to one order of
                      magnitude larger than classical thermophoretic mobility.
                      This study improves the understanding of the underlying
                      mechanisms that govern the transport of ions in nanoporous
                      media, which could set the stage for diffusional
                      metamaterials induced by specific thermal fields.},
