Magnetic resonance imaging has enabled the development of a completely novel type of viscometer. This technique is based on the capacity of MRI to accurately measure velocity profiles in opaque liquids. Its potential applications include many systems of industrial relevance, such as polymer melts and slurries. The data presented here clearly show that a wide range of fluid behaviors can be measured.

The underlying physical principles of NMR have been established and are well understood.8 Applications of both solid- and solution-state NMR spectroscopy can be found in many different disciplines. It is routinely used in structural elucidation of organic and inorganic compounds, polymers, and biomolecules (e.g., proteins, nucleic acids, and carbohydrates). Additionally, NMR can be used to study molecular interactions (e.g., protein-protein and protein-ligand), molecular dynamics, and chemical reactions. It has also been used extensively in medical research and imaging (magnetic resonance imaging).

Magnetic resonance imaging (MRI) has been applied to the study of the distribution of fluid components (i.e., water or a polymer used as consolidant) in a porous material such as stone or waterlogged wood by a direct visualization of the water or fluid confined in the opaque porous medium [13].

NMR studies of polymers, and magnetic resonance imaging (MRI). In an interesting study, the solid state CPMAS NMR data sets for a pharmaceutical compound were analyzed using DECRA. In these experiments the exponential decay of the signal intensity in the data matrix D decayed as a result of H spin lattice T relaxation. The DECRA results allowed the resolution of two distinct crystalline polymorphs within the compound. DECRA has also used to analyze the C MAS NMR spectra of irradiated cross-linked polyolefin cable insulation. In this study, the two proportional data...
