Thermodynamics of CeSiO4: Implications for Actinide Orthosilicates

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...

Thermodynamics and Lattice Vibrations of Minerals 4. Application to Chain and Sheet Silicates and Orthosilicates

This paper is the fourth in a series relating the lattice vibrational properties to the thermodynamic properties of minerals. The temperature dependence of the harmonic lattice heat capacity is calculated from a model which uses only elastic, crystallographic, and spectroscopic data for the following minerals: calcite, zircon, forsterite, grossular, pyrope, almandine, spessartine, andradite, ky...

Toward Understanding the Thermodynamics of TALSPEAK Process -- Medium Effects on Actinide Complexation

The ingenious combination of lactate and diethylenetriamine-N,N,N’,N”,N”pentaacetic acid (DTPA) as an aqueous actinide-complexing medium forms the basis of the successful separation of americium and curium from lanthanides known as the TALSPEAK process. While numerous reports in the prior literature have focused on the optimization of this solvent extraction system, considerably less attention ...

Thermodynamics of Ligand-Protein Interactions: Implications for Molecular Design

Biologically relevant macromolecules, such as proteins, do not operate as static, isolated entities. On the contrary, they are involved in numerous interactions with other species, such as proteins, nucleic acid, membranes, small molecule ligands, and also, critically, solvent molecules. These interactions often display a remarkable degree of specificity and high affinity. Fundamentally, the bi...
