Investigation of dynamic and structural properties in various materials using nuclear magnetic resonance
EMSL Project ID

Abstract
The dynamic properties of molecules (gases/fluids) confined in the pores are closely correlated with the pore parameters, such as pore size, surface-to-volume ratio, and tortuosity. Then the pore geometries can be revealed from the translational and rotational dynamics of the confined molecules. While pulsed-field gradient (PFG) NMR and nuclear relaxations (T1, T2, T1rho, etc.) are used to obtain the translational and rotational mobilities of molecules, respectively, the relaxations also can be used to estimate the translational mobility of confined molecules when PFG-NMR is not available due to the surface interactions that enhancing relaxations. To examine the pore structure of host porous materials like polymers and MOFs, the dynamic properties of confined molecules will be studied by using PFG-NMR and relaxation measurements. Also PFG-NMR and relaxation measurements will be performed to elucidate the solvation structure of electrolytes in the bulk and on the electrolyte-electrode interfaces.
