27Al and 29Si MAS NMR investigations of cordierite glass, mu- and alpha-cordierite.

27Al and 29Si Magic-Angle Spinning NMR results are reported for conventionally prepared glass of cordierite stoichiometry (2MgO.2Al2O3.5SiO2), the metastable high-quartz solid solution (mu-cordierite) and the high-temperature polymorph of cordierite (alpha-cordierite).

[P-31 NMR studies of in vivo regeneration of preservative-induced changes in 2,3-diphosphoglycerate content of erythrocytes].

In this study, we analyzed the regeneration kinetics and the reversibility of the 2.3-DPG reduction in stored red cells after transfusion. Within 3 h after transfusion the 2.
