Lindner et al. carried out detailed studies on the use of the sol-gel procedure to obtain new materials as suitable matrices [45]. A co-condensation of Si(OR)4, Si(OR)3-spacer-Si(OR)3 and Si(OR)3-spacer-ligand resulted in new hybrid materials, the properties of which strongly depended upon the spacer and the ratio of the different components used. Most of these materials were characterised with IR, EXAFS, and EDX spectroscopy, scanning electron microscopy and solid state NMR spectroscopy. Solid state 31P NMR was used to quantify the mobility of the interphases the changes in line-...

As stated earlier, after the catalytic transformation was over, a black gummy precipitate was observed. This black solid was filtered and washed with excess of benzene. The solid was characterized by scanning electron microscopy (SEM), FT-IR spectroscopy, and solid state Si NMR spectroscopy. Solid state Si NMR spectra showed signals corresponding to Si-H ( 36.15), Si-OCOR (—64.74), Si-OH... 

Solid-State NMR spectroscopy of protein complexes has been reviewed by Sun el al The article considers protein-protein interactions, which often result in the formation of protein assemblies that are large in size, insoluble, and difficult to crystallize, and therefore are challenging to study by structural biology techniques, such as single crystal X-ray diffraction and solution NMR spectroscopy. Solid-state NMR spectroscopy is shown to be...

An extensive and systematic study on cationic and anionic substitution in hydroxyapatite structures was carried out. Lead and vanadium were chosen for the exchange, due to their known effects on the redox and catalytic properties of hydroxypatites. Hydroxyapatites with variable Pb and V contents, were synthesized and characterized by multinuclear, including the unusual " Ca, NMR spectroscopy. Solid-state NMR allowed an analysis of the chemical environment of every ion after substitution into the hydroxyapatite network. ...

A second field in structural biology, where solid-state NMR has proven to be useful, is the study of membrane proteins. As lipid bilayers - the natural environment of membrane proteins - tend to form liposomes or vesicles with rotatiOTial correlation times too large for solution-state NMR spectroscopy, solid-state NMR spectroscopy has been demonstrated to be a viable method to gain insight into complex membrane protein systems. In the following section we give a brief overview over selected systems where solid-state NMR could provide useful information. For a more comprehensive overview we refer to recent review articles [4,146,156,157].
