Sensing the Spin of an Individual Ce Adatom

The magnetic moment of rare earth elements originates from electrons in the partially filled 4f orbitals. Accessing this moment electrically by scanning tunneling spectroscopy is hampered by shielding of outerlying orbitals. Here, we show that we can detec ...

Advanced materials characterization and modeling using synchrotron, neutron, TEM, and novel micro-mechanical techniques-A European effort to accelerate fusion materials development

Cécile Hébert

For the realization of fusion as an energy source, the development of suitable materials is one of the most critical issues. The required material properties are in many aspects unique compared to the existing solutions, particularly the need for necessary ...

Uranium redox transition pathways in acetate-amended sediments

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Daniel Scott Alessi, Malgorzata Alicja Stylo

Redox transitions of uranium [from U(VI) to U(IV)] in low-temperature sediments govern the mobility of uranium in the environment and the accumulation of uranium in ore bodies, and inform our understanding of Earth's geochemical history. The molecular-scal ...

Uranyl complexes formed with a para-t-butylcalix[4]arene bearing phosphinoyl pendant arms on the lower rim. Solid and solution studies

Jean-Claude Bünzli

The current interest in functionalized calixarenes with phosphorylated pendant arms resides in their coordination ability towards f elements and capability towards actinide/rare earth separation. Uranyl cation forms 1: 1 and 1: 2 (M : L) complexes with a t ...
