1. X-ray absorption spectroscopy with application to rare earths

Philippe SAINCTAVIT (SOLEIL)

Lanthanides et actinides

Conférence Invitée

In this presentation we shall give an introduction to the technique of X-ray absorption spectroscopy (XAS).
In a first step, we shall focus on the basic theoretical description of XAS with a specific attention dedicated to the selection rules and we shall also review the theoretical framework necessary for the description of the electronic structures of the rare earths in the context of XAS....

14. From Swichable Nanomagnets to Magnetic Dendrimers

Valérie MARVAUD (CNRS - IPCM)

Lanthanides et actinides

Oral

High spin molecules and photomagnetic compounds are attracting increasing attention due to their potential interest in memory devices or optical switches. On the one hand, lanthanides have been recognized as viable building blocks for single molecule magnets (SMM) due to their strong single-ion anisotropy. On the other hand, octacyanometalates could be considered as interesting precursors not...

19. NMR paramagnetic effects of lanthanide complexes under high hydrostatic pressure to probe the structure of proteins and contrast agents.

Lanthanides et actinides

Oral

The application of hydrostatic high-pressure (HP) is now a recognized tool to modify biomolecular conformational landscapes in a mild and largely reversible manner. HP combined with NMR spectroscopy (HP-NMR) has been extensively used over the years to characterize the folding properties and the dynamics of soluble proteins by stabilizing conformational states that are lowly populated at...

24. Is radiochemistry real coordination chemistry?

Lanthanides et actinides

Oral

Since the discovery and early developments of radiochemistry by P. and M. Curie at the beginning of the XXth century, the chemistry of radioactive nuclides has undergone spectacular progresses during the first half of the century. Since then the term radiochemistry broadly covers the chemistry at tracer scale from early Curie’s methodologies1 and the chemistry of radionuclides. The IUPAC gold...
