DOI: 10.1002/adfm.200801907 Multiferroic heterostructures of Fe3O4/PZT (lead zirconium titanate), Fe3O4/ PMN-PT (lead magnesium niobate-lead titanate) and Fe3O4/PZN-PT (lead zinc niobate-lead titanate) are prepared by spin-spray depositing Fe3O4 ferrite film on ferroelectric PZT, PMN-PT and PZN-PT substrates at a low temperature of 90 8C.

Spherulitic crystallisation is a mode of growth of crystals from the melt. Considerable attention has been given to spheroidal graphite formation, providing detailed information about the internal microstructure of the spherulites in spheroidal (SG irons) and compacted graphite irons (CG irons) (Stefanescu, D., 1990. Cast Irons. ASM Handbook, 10th ed., vol.(More)
We used 7Li NMR spin-lattice (T1) and spin-spin (T2) relaxation time measurements to investigate the binding of Li+ in human red blood cell (RBC) suspensions. In RBCs containing 1.4 mM Li+, the intracellular 7Li NMR T2 relaxation value (0.30 +/- 0.03 s) was much smaller than the corresponding T1 value (6.0 +/- 0.1 s), yielding a ratio of T1 to T2 of 20.

A reproducible 7Li nuclear magnetic resonance (NMR) method, based on a modified inversion recovery (MIR) pulse sequence, was used to discriminate between intra- and extracellular lithium concentrations in red blood cell (RBC) suspensions. The rates of Na(+)-Li+ countertransport determined by the 7Li NMR method were significantly correlated with the(More)
