A NMR investigation of adsorption/desorption hysteresis in porous silica gels

The purpose of this study is to investigate possible differences in geometry and connectivity of the liquid phase in a partially water-satured porous medium between the adsorption and the desorption branches, using a series of silica gels. This was done by comparing the T 1 and T 2 relaxation times...
