Dynamic NMR Relaxometry Highlights Drying-Induced Heterogeneity and Structural Reconfiguration in Colloidal Gels.
In this work, we introduce a dynamic NMR relaxometry approach to monitor gel drying not as a function of time, but through the evolution of the transverse relaxation time (T2) as a function of gel saturation. This formulation enables us to track, with high temporal resolution and in a noninvasive manner, how homogeneit...
