Interaction Mechanism between Cellobiose and Imidazolium Halide-based Ionic Liquids
BioResources, 2023 Ionic liquids (ILs) are excellent solvents for cellulose, but the dissolution mechanism is not deeply understood. In the present study, cellobiose was used as a model of cellulose, and the imidazolium halide-based ILs with the same cation of 1-butyl-3 ...

NMR chemical shift imaging [PDF]
Computerized Medical Imaging and Graphics, 1989 Chemical shift imaging combines the spatial information provided by a conventional nuclear magnetic resonance (NMR) image with the chemical shift spectral information provided by NMR spectroscopy. In order to preserve the chemical shift information and provide a spatial map simultaneously, new NMR imaging methods have been developed.
