Chemical shift imaging of molecular transport in colloidal systems: Visualization and quantification of diffusion processes
Magnetic resonance imaging with chemical shift resolution is demonstrated to provide detailed information about molecular transport on the macroscopic scale in complex colloidal systems. The concentrations of species with distinct 1 H resonance lines can be quantified from spatially resolved, high-resolution, H-1 nuclear magnetic resonance spectra. The method is demonstrated by experiments on thre
