Mesoporous γ-alumina because of its homogeneous pore size distribution, represents a good support for alkali metals. Controlled thermal decomposition of impregnated sodium azide on such support yields a superbasic catalyst for the double bond migrat

The Al coordination state of molecular sieve SAPO-37 has been studied by 27 Al multiple quantum (MQ) MAS NMR spectroscopy. Although the 1D 27 Al MAS NMR spectrum of the aluminum sites show a complex pattern, the 3Q MAS NMR spectra of SAPO-37, submitt

Water-extractable arabinogalactan-peptides (WE-AGP) were isolated from flour of eight different wheat cultivars (harvest year 1996). Little structural variation in WE-AGP of flour of the different wheat cultivars was observed. The arabinose-to-galact

Cross-polarization (CP) combined with magic-angle spinning (MAS) is the most popular technique used for the high-resolution solid 13 C study of occluded templates in zeolitic materials. Depending on the mobility of the incorporated templates the high

Although high-resolution NMR spectra can be obtained in solids, the use of27Al NMR to investigate the structure of aluminosilicate and aluminophosphate molecular sieves has been severely limited because anisotropic second-order quadrupolar interactio

Summary Both P and Al MAS NMR spectra of samples of excessively fertilized sandy soil provided information about the P and Al speciation. Peak deconvolution was used to interpret reliably and quantitatively the 31P NMR spectra recorded. Most of the P

In the 29 Si MAS NMR spectra of Na-exchanged FAU/EMT zeolite intergrowths, the signals from the FAU and EMT phases coincide. However, after Li ion exchange of such zeolites, an upfield shift of the FAU signals by 2-3 ppm occurs and, consequently, par
