According to the phase diagram of lithium niobate (LN) a decomposition of congruently melting LN with segregation of a niobium rich phase LiNb 3 O 8 (L3N) has been observed. It occurs at the surface and at defects within the LN crystals at temperatures significantly higher than 300 C. L3N crystals g

β¦ Synopsis
The simulations of NMR spectra of 93 Nb nuclei for different models of intrinsic defects in single crystal of congruent lithium niobate have been performed. It has been shown that the most probable defects in LiNbO 3 are complex (Nb Li + 3 V Li ) and isolated V Li .

The aim of this study was to analyze Na + fluxes in whole perfused hearts using Li + as a Na + congener and 7 Linuclear magnetic resonance as a detection method. Hearts were equilibrated for 32 min with 15 mM LiCl added to P 1 -free Krebs-Henseleit buffer (intracellular space (ICS) [Li + ] = 21.5 Β±
## Abstract Lasalocid metal salts were combined with 1 : 1 lithium and 2:2 potassium, rubidium, and cesium to form complexes. The nature of the lasolocid salt complexes was studied in a solid and chloroform by FTIR spectroscopy in the middle and far IR regions. The process of the complexation of li
