Abstract
Fundamental knowledge of an influence of structural inhomogeneity on transport properties
of nanostructured systems in a broad range of length scales between hundreds of
nanometers and tens of microns can be obtained by using a pulsed field gradient (PFG) NMR
technique that combines advantages of high field (17.6 T) NMR and high magnetic field
gradients (up to 30 T/m). This technique has been recently introduced at the University of
Florida in collaboration with the National Magnet Lab. Several examples of diffusion studies
using this technique will be discussed in detail. These examples include uncovering transport-structure
relationship in room temperature ionic liquids and their mixtures with water and
carbon dioxide as well as in multicomponent lipid bilayers containing membrane domains. In
addition to a more conventional 1H PFG NMR, also 13C PFG NMR was used.
