To characterize the structure of silk, various techniques, namely X-ray diffraction (XRD), vibrational spectroscopy, and cross-polarization magic-angle spinning nuclear magnetic resonance, and so on, have been adopted. Hu et al. reported a study of self-assembled yS-pleated sheets in Bombyx mori silk fibroin films using... [Pg.212]

CROSSED POLARIZATION AND MAGIC ANGLE SPINNING NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY (CP/MAS NMR)... [Pg.46]

Both of these methods have been used for DOM isolation from major rivers and the surface ocean, and the general characteristics of these fractions of DOM are presented in Table I. The major C functional groups of humic substances and ultrafiltered DOM (UDOM) have been characterized by solid-state, cross-polarization magic angle spinning 13C nuclear magnetic resonance (NMR) spectroscopy. The samples of humic substances that were characterized by NMR spectroscopy were collected from the Amazon River... [Pg.125]
