Multiple-pulse (m.p.) sequences for high-resolution nuclear magnetic resonance (NMR) in solids were introduced in 1968 by the MIT NMR group (Waugh et al., 1968). At that time the idea was to apply the m.p. sequences to strongly coupled spin 5 systems, in practice, to samples with abundant nuclei or protons and no other nuclei with nonzero spin. The...

Spectral studies such as Fourier transform infrared/attenuated total reflectance (FTIR/ATR) analysis, solid-state or pulse field gradient (PFG) nuclear magnetic resonance (NMR), x-ray diffraction (XRD) or small angle x-ray scattering (SAXS) analysis, and Raman study are basically the characterization methods for hybrid/ composite membranes. Sometimes, the multiple spectral analyses are necessary to better understand the structure-property relationship for a kind of composite polyelectrolytes.
