Magnetostructural phase separation and giant isotope effect in R0.5Sr0.5MnO3

Electrochemical isotope effect and lithium isotope separation.

A large electrochemical isotopic effect is observed upon the electrodeposition of lithium from solutions of propylene carbonate producing isotopically light metal deposits. The magnitude of fractionation is controlled by the applied overpotential and is largest close to equilibrium. Calculated partition function ratios for tetrahedrally coordinated lithium complexes and metallic lithium predict...

Isotope Effects, Isotope Separation and Isotope Fractionation

Effect of flavonoids on the phase separation in giant unilamellar vesicles formed from binary lipid mixtures.

Confocal fluorescence microscopy have been employed to investigate phase separation in giant unilamellar vesicles prepared from binary mixtures of unsaturated dioleoylphosphocholine with saturated phosphocholines or brain sphingomyelin in the absence and presence of the flavonoids, biochanin A, phloretin, and myricetin. It has been demonstrated that biochanin A and phloretin make uncolored doma...

Phase separation and a tendency to form inhomogeneous structures seems to be a generic property of systems with strongly correlated electrons. After shortly summarising the existing theoretical results in this direction, I concentrate on the phenomena in doped manganites. I discuss general theoretical results on the phase separation at small doping and close to the doping x = 0.5. The " global ...

Molten Salts and Isotope Separation

The work on molten salts and isotope separation performed over the years at Université Pierre et Marie Curie and at Collège de France is critically reviewed. This research, closely related to A. Klemm’s pioneering contributions, leads among other things to the discovery of the effect now called the ‘Chemla effect’, after the late Professor Marius Chemla. These studies of ionic motions in melts,...
