Thenoyltrifluoroacetone (TTA)–Carbon Dot/Aerogel Fluorescent Sensor for Lanthanide and Actinide Ions

Magnetoresistance in actinide and lanthanide intermetallics

Magnetoresistance studies in narrow 5f band materials show that a giant drop of electrical resistance accompanies frequently field-induced reorientation of uranium magnetic moments in antiferromagnets. We show that a strong spin-dependent scattering, originating in the strong 5f hybridization with conduction electron states, is the most plausible origin of this effect, the magnitude of which by...

Relativistic Configuration Interaction Calculations for Lanthanide and Actinide Anions

Structure and Thermodynamics of Lanthanide and Actinide Complexes in Solution

Several questions of importance in the study of lanthanide and actinide coordination compounds are reviewed. There is considerable evidence that in aqueous solution the primary coordination number is nine for the ions La(ni) through Nd(m) and eight for the ions heavier than Gd(m). While it seems that some degree of covalency exists in the metal—ligand bonding a model of electrostatic bonding se...

Lattice disorder in strongly correlated lanthanide and actinide intermetallics.

Lanthanide and actinide intermetallic compounds display a wide range of correlated-electron behavior, including ferromagnetism, antiferromagnetism, nonmagnetic (Kondo) ground states, and so-called 'non-Fermi liquid' (NFL) behavior. The interaction between f electrons and the conduction band is a dominant factor in determining the ground state of a given system. However, lattice disorder can cre...

Lanthanide speciation in potential SANEX and GANEX actinide/lanthanide separations using tetra-N-donor extractants.

Lanthanide(III) complexes with N-donor extractants, which exhibit the potential for the separation of minor actinides from lanthanides in the management of spent nuclear fuel, have been directly synthesized and characterized in both solution and solid states. Crystal structures of the Pr(3+), Eu(3+), Tb(3+), and Yb(3+) complexes of 2,9-bis(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-1,2,4-benzotriaz...
